“At present, the continuous desulfurization equipment and technology for atmospheric pressure vulcanized rubber powders has matured the industrial production process, and its promotion has also had three favorable conditions, namely, mature technology, encouragement of national policies, and strong willingness to promote enterprises. The continuous atmospheric desulfurization technology for reclaimed rubber and vulcanized rubber powders has become the best choice for the green rubber industry to achieve green development and upgrading.†August 9-10, China Rubber Industry Association waste rubber Comprehensive use of the branch held in Chengdu in the vapour rubber powder atmospheric pressure continuous desulfurization technology exchange seminar, the branch secretary Cao Qingxin said. Fan Rende, president of the China Rubber Industry Association, said that on the one hand, China is currently the world’s largest consumer of rubber and the world’s largest producer of waste rubber. The amount of used tires is increasing. This is China’s waste rubber recycling industry. Provide sufficient resources. On the other hand, China is also a country with scarce rubber resources. Raw rubber resources mainly depend on imports. Making full use of waste rubber resources is a prerequisite for ensuring the recycling of rubber recycling resources. However, the recycling of rubber should be ensured by harmless recycling and environmental protection. In this process, energy conservation and environmental protection must be ensured and secondary pollution must not occur. In traditional reclaimed rubber production, pollution is mainly generated during the desulfurization process. After the waste tires and waste rubber products are crushed into rubber powder, the desulfurization agent reacts with the desulfurization tank. This unloading process has a large amount of odor exhaust emissions, causing dissatisfaction from the surrounding masses. Xiao Guanlu, chairman of Dujiangyan New Era Industry and Trade Co., Ltd., said that any accidental production safety accidents and environmental protection issues of reclaimed rubber companies will cause other companies in the reclaimed rubber industry to fall into the shadow of public opinion and become the target of public criticism. The living environment of reclaimed rubber enterprises requires all companies to work together to achieve continuous improvement. The promotion of green and environmentally friendly reclaimed rubber production process has become a business must do. In response to the problem that traditional dynamic desulfurization produces a large amount of waste water, waste gas, and unsafe factors, many companies in the industry have spent a lot of time and effort on developing new reclaimed rubber production technology, with Dujiangyan New Era Industry and Trade Co., Ltd. and Shandong Jinshan Rubber & Plastics Co., Ltd. Equipment Technology Co., Ltd. developed on behalf of the single spiral, double spiral atmospheric pressure, frequency control, digital intelligent temperature control, continuously linked production of vulcanized rubber powder atmospheric continuous desulfurization complete sets of equipment to come to the fore. The process will vulcanize the rubber powder, activator, softener, etc. to the desulfurization machine through stirring. The desulphurization and jacket spiral cooling are used to achieve desulfurization and cooling under the sealed conveying condition in the screw device to achieve atmospheric desulfurization and reduce energy consumption. The production process has no waste water and no exhaust gas. Compared with the traditional dynamic desulfurization method, atmospheric continuous desulfurization method can save more than 20, and no waste water, exhaust emissions, but also to reduce the operating staff by 2/3, reduce the use of steel 3/4 equipment, floor space reduction by 2/3, Great savings in land. In the “National Circular Economy Technology, Process, and Equipment Catalogue (First Batch) Encouraged by the State,†published on June 1, the continuous desulfurization equipment for vulcanized rubber powder at atmospheric pressure is the only one listed in the waste rubber comprehensive utilization industry as a national encouragement and promotion. Circular economy technology, process and equipment. Xiao Guanlu told the reporter that after the mature application of atmospheric desulfurization technology and the transformation of production of environmentally friendly reclaimed rubber complying with the requirements of EU REACH, the company will bid farewell to the bad image of the past society and have enough energy to accept public opinion and the supervision of the surrounding people. . At present, the New Era Company has established cooperative relationships with 15 companies including Shandong Xindongyue Group Co., Ltd., Shandong Dongying City Lijin County Xinxing Chemical Plant, Henan Sanmenxia City Zhongying Technology Co., Ltd., and sold more than 80 sets of atmospheric pressure. Continuous desulfurization technology and equipment are in stable operation. The reporter noticed that in the process of organizing a visit to a new era during the conference, delegates cherished the opportunity to learn more about the operation and operating parameters of each equipment in the workshop and did not familiarize themselves with the site. The smell of odor was very satisfactory, and many company representatives also took samples of reclaimed rubber just coming out of the production line. However, some representatives also believe that the actual single-line production of this technology is currently small. Xiao Guanlu told reporters that the New Era Company has made active efforts to expand its single-line production capacity for new technologies. At present, the company has eliminated 5 tons of Nissan equipment that has produced nearly 20 years. At the end of 2011, it completed the development of an atmospheric continuous desulfurizer with a daily output of 10 tons and 15 tons. After several months of trial operation, it fully met the design requirements and not only ensured the normal operation of the equipment, but also the quality of reclaimed rubber products fully met the high standards. Xiao Guanlu said that at present, the company's development focus is to further transform the atmospheric continuous desulfurization equipment according to customer requirements, achieving the goal of simpler operation and longer operating time.
