“Despite the profit growth of 38 key member companies in the first seven months of this year, 14.96%, it should be soberly seen that while the economic benefits of the industry are growing, there is still a big gap between resource-saving and environment-friendly enterprises. In particular, the current environmental protection situation in the industry is grim, and the protection of the environment has become the historical mission of the comprehensive utilization of waste rubber.” China National Rubber Industry held at the “National Waste Rubber Utilization Information and Technology Exchange Seminar” held in Linyi, Shandong from September 24th to 26th. Secretary General Cao Qingxin of the Association for the Comprehensive Utilization of Waste Rubber said to the reporter.
Exhaust gas disturbs people to force industry upgrade
Waste tire processing and production reuse is a national encouraged circular economy project, but the industry is accompanied by environmental pollution problems, and rubber waste gas has become a major "public hazard" to nearby residents.
According to the reporter's understanding, on June 21 last year, after CCTV reported the environmental pollution problem of waste rubber enterprises in Yutian County, Hebei Province, the local government took measures to cut off electricity and shut down the waste rubber processing plants involved in the report. Three companies, Tianjin Jida Company, Tianyu Company and Dongchang Company, have a daily output of 310 tons of recycled rubber and were forced to shut down. The annual output of Jiangsu Haimen, which has 14 reclaimed rubber production enterprises, was 150,000 tons. Last year, the environmental protection department carried out the first round of rectification. This year, the rubber waste gas treatment and re-propulsion project was implemented. In addition, from time to time, reports of law enforcement inspections of reclaimed rubber enterprises in Hebei, Shandong and Shandong have been reported to the media. The "Environmental Protection Law of the People's Republic of China" approved by the Standing Committee of the National People's Congress will be officially implemented on January 1 next year.
The waste rubber comprehensive utilization industry faces a situation of “pre-blocking, followed by chasing troops” and not being optimistic about cross-border funds. The problem facing the industry is to solve the problem of “useful” of waste rubber tires and how to achieve “good” development and become a resource-saving and environment-friendly “two-type” development enterprise.
"The reason why this meeting was chosen to be held in Linyi, Shandong is because the three companies that arranged the visit have their own characteristics." Cao Qingxin told reporters that Linyi County Zhongtai Rubber Products Co., Ltd. is the automation of traditional enterprise clean production and rubber powder production. Representative; Jixian Dongsheng Rubber Co., Ltd. is a model for independent research and development of continuous pressure desulfurization production line, realizing automatic production, and extending the rubber powder industry chain to realize the high value-added of rubber products such as inner tube; Shandong Qihe Rubber Industry Co., Ltd. Through technological transformation, traditional enterprises have adopted the role of automated production to reduce staff and increase efficiency and achieve green production and sustainable development.
"In the past two years, the waste rubber comprehensive utilization industry has adopted a diversified approach of combining production, study and research, project establishment, and independent research and development, and has effectively innovated the three basic issues of 'secondary pollution', 'energy saving' and 'automatic control'. Liu Zengyuan, head of the expert group of the Waste Rubber Comprehensive Utilization Branch, said.
According to experts, the biggest pollutant in the recycled rubber manufacturing industry is hydrogen sulfide emissions (odor), followed by polycyclic aromatic hydrocarbons and heavy metals. The main culprit is coal tar softener, which must be withdrawn from the market and replaced with environmentally friendly softeners. Greatly solve the secondary pollution problem of recycled rubber. It is understood that in order to make the recycled rubber products meet the requirements of "product safety, safety of use", in line with the EU REACH regulations, the elimination of toxic and harmful coal tar softeners, the waste rubber utilization industry has begun to develop "environmental-type renewable rubber self-regulation specifications", will It was completed in December this year.
Significant achievements in environmental protection and energy saving equipment development
The core of recycled rubber manufacturing is desulfurization and plasticization unit. High-temperature and high-pressure dynamic desulfurization tank and atmospheric pressure continuous desulfurization machine are the two major process equipments used in the industry at this stage. “High-temperature and high-pressure dynamic desulfurization tanks have the widest application and the most mature technology, while the continuous pressure desulfurization equipment and process technology are the development direction, which is the key to promote the transformation and upgrading of the industrial reclaimed rubber desulfurization and plastic powder plasticization equipment. The major enterprises of the big genre are re-innovating process technology to solve the environmental pollution problem of the waste rubber comprehensive utilization industry." Cao Qingxin said.
“We have produced more than 1600 high-temperature and high-pressure dynamic desulfurization tanks with a market share of over 70%, 95% of which are still in use. Many new reclaimed rubber projects or technological transformation and expansion projects still use dynamic desulfurization tanks. Dynamic desulfurization tanks The problem is that a large amount of high-temperature exhaust gas containing various toxic and harmful organic substances is discharged during the process of desulfurization, pressure discharge and discharge, which is horrible and pollutes the environment.” Wang Changbin, chairman of Huainan Petrochemical Machinery Equipment Co., Ltd. said, “through the research institute We have developed an energy-saving and environmentally-friendly waste rubber regenerative tank, and passed the on-site appraisal in late May this year. Experts believe that there is no waste water, no waste gas, no odor, no pollution. It has been sold for more than three months. More than 60 units."
The main production enterprises of atmospheric continuous desulfurization plasticizers - Dujiangyan City New Times Industry and Trade Co., Ltd., Shandong Jinshan Rubber & Plastic Equipment Technology Co., Ltd., Pinglu Kangle Rubber & Plastics Technology Development Co., Ltd., etc., in addition to nearly 100 domestic products In addition to home business applications, it is also exported to Southeast Asia, India, Europe, North America and other countries and regions. Although its environmentally-friendly and safe desulfurization method has been widely recognized in the industry, the re-innovation work continues, especially the research and development of pulverization, desulfurization and calendering refining to realize the whole process of linkage research is in full swing.
“Desulfurization and plasticizer is conducive to environmental protection. In the process of equipment improvement, the focus is on process technology. It is not only concerned with the appearance. Especially the linkage of the upper and lower processes, the core is to master the positive desulfurization point of reclaimed rubber, the waste collagen material and other factors. Impact, it is not constant and needs attention.” Xiao Guanlu, chairman of Dujiangyan New Times Industry and Trade Co., Ltd. said.
“The application of Jiangyin Meisen’s new plasticizer has achieved desulfurization at the positive desulfurization point, which is not only energy-saving and environmentally friendly, but also because it is low-temperature desulfurization, no water is added during plasticization, and smokeless gas is produced during rubber mixing, completely changing the regeneration. The production appearance of the rubber enterprise has truly realized the environmentally friendly production of Qing Dynasty.” Xiao Qinlong, manager of Shanghai Xiaoyou Rubber Co., Ltd. said.
In addition to the above two desulfurization processes and equipment, the industry's old expert Dong Chengchun also introduced the ultrasonic atmospheric pressure continuous desulfurization production process and its feasibility. “This method belongs to the physical desulfurization method. It does not need to add an activator. It can be added with softeners properly, which can save energy and reduce emissions, reduce production costs, and be free from pollution.” He said that through the unremitting efforts and exploration of the industry, the ultrasonic desulfurization industry It should not be a long time.
In the "three small" aspects of the frequent occurrence of safety production accidents, the industry associations also made a strong appeal to require enterprises to implement the occupational health and safety system and adhere to the "people-oriented" safety production concept. Advanced enterprises have selected the country's recommended tire crushing and crushing equipment, and achieved industrial linkage, so that the first process of scrap tire crushing is no longer a “drag step” process, and the industry's overall production automation level and large-scale production have increased a big step. .
In Shandong Yuhe Rubber Industry Co., Ltd., the reporter saw that after the automatic feeding and discharging device was modified, the rubber powder production realized the reduction of people and efficiency. After the high starting point, the innovative and environmentally-friendly reclaimed rubber mixing machine, plasticizing machine and Dalian Baofeng Machine Manufacturing Co., Ltd. developed a new type of high-efficiency and energy-saving automatic reclaimed rubber complete sets of equipment, and increased the conveyor belt dispensing device. And the cutting device basically realizes the full automatic process.
Liu Shuling, general manager of Beijing Tianzhongfang Technology Development Co., Ltd., an exhaust gas purification equipment manufacturer, told the reporter that the company has developed environmental protection equipment such as “exhaust gas purification and treatment machine” and “waste water purification machine” for tire companies and reclaimed rubber enterprises. Yu Wanda Baotong Tire Company, Guizhou Yugao Transmission Belt Company, Shandong Xindongyue Company and other enterprises. “Nantong Huili Rubber Co., Ltd., the largest waste rubber comprehensive utilization enterprise in the country, installed two large-scale exhaust gas treatment equipments in mid-June to solve the problem of rubber exhaust gas pollution from the source. Nanhui Company will also use the wastewater purification produced by our company. Processing device." Liu Shuling said.
Industry transformation requires policy guidance
Since the beginning of the new century, the reclaimed rubber industry has achieved rapid development. While bringing economic benefits, environmental pollution problems cannot be ignored. Environmental protection forces the industry to transform, but it requires a process that requires the guidance and support of the national industrial policy.
Not long ago, the National Development and Reform Commission's second batch of resources comprehensive utilization of the "Double Hundred Project" backbone enterprises announced, Hangzhou Zhongce Rubber Cycle Technology Co., Ltd. and Shandong Laiwu Fuquan Rubber Co., Ltd. were listed. It is understood that the National Development and Reform Commission will strengthen guidance on the development of key enterprises, give priority support to key projects undertaken by key enterprises, and further study and improve policies for encouragement and support with relevant departments.
Liu Wei, deputy general manager of Hangzhou Zhongce Rubber Cycle Technology Co., Ltd., said that the company mainly carries out a series of treatments on the recycling, repair and refurbishment of used tires of Zhongce Rubber Group Co., Ltd., the largest tire manufacturer in China. The refurbished tires produced in 2012 were recognized as comprehensive resource utilization products by the Zhejiang Provincial Economic and Information Department. In late May of this year, the company entered the first batch of management enterprises that were in compliance with the "Tire Renovation Industry Access Conditions" announcement. It is understood that the first batch of announced companies have only 23 tire refurbished, recycled rubber and rubber powder enterprises.
Yin Zuopeng, general manager of Shandong Yuhe Rubber Industry Co., Ltd. introduced that during the implementation of the annual investment of 480,000 tons of green recycled rubber renovation project with a total investment of 48 million yuan, the company actively strives for national policy support and has reported 6 national, provincial and municipal projects. With the support of 14.65 million yuan, it will complete 6 new high-efficiency and energy-saving automatic reclaimed rubber complete equipment production lines, 5 sets of environmentally-friendly and efficient reclaimed rubber mixing machine and plasticizing machine. At the beginning of 2015, it will form 30,000 tons of green reclaimed rubber production capacity. . Under the premise of consolidating the scale of rubber powder, we will step out of the first step of industrial transformation and upgrading.
“As a member of the exhaust gas treatment equipment manufacturer, we are willing to provide quality products and services for the reclaimed rubber industry.” Liu Shuling said, “But some reclaimed rubber companies still have the luck to promote a move, last year’s environmental protection When it was very tight, I was ready to launch the exhaust gas treatment equipment, and this year I put the procurement plan on hold."
The waste rubber has been upgraded by the industry's energy conservation and environmental protection work, but the proposed measures have been put into practice, so that the tooling equipment is intelligent and automated, the process is energy-saving, environmental protection and clean production, safe production, occupational health, and It is a long-term and arduous task to shoulder the social responsibilities.
"The historical mission of China's waste rubber comprehensive utilization industry to undertake environmental protection and resources will not change, and the pace of structural adjustment and product upgrading of the waste rubber comprehensive utilization industry will accelerate." Cao Qingxin said.
