According to the China Association of Controlled Chemicals, the industry standard “Safety Technical Regulations for Phosphorus Trichloride†(discussion draft) drafted and drafted by the Association has been issued and solicited at the recently held annual meeting of the Phosphorus Trichloride and other Phosphorous Products Collaborative Group. The opinions were revised and reported to the Safety Production Office of the China Petroleum and Chemical Industry Federation. By the end of this year, the Ministry of Industry and Information Technology will submit a report to the Ministry of Industry and Information Technology, which is expected to be issued next year. The "Procedures" has made mandatory safety requirements for the production, storage, transportation, and use of phosphorus trichloride products, and it will also play a role in the structural adjustment of the phosphorus trichloride industry. According to Wu Jinrong, director of the China Monitoring and Control Chemicals Association, the former Ministry of Chemical Industry had ever had industry standards for phosphorus trichloride safety technology in the early 1980s, but it has increased with the requirements for safety and the environment, as well as during production and transportation. Some new issues and so on, the old standard has long been inapplicable. "There are too many small businesses in the industry. Many businesses are too unregulated and their security risks are very serious. They not only threaten social security, but also are not conducive to the implementation of the CWC's compliance work. Therefore, the industry has introduced such a safety regulation. There is a loud voice," said Wu Jinrong. Yang Linhui, head of the trading department of China Minhua Chemical (Group) Corporation, stated that the "Regulations" are of great significance. At present, the technology of phosphorus trichloride has been greatly improved compared with before. According to the national regulations, the project must be subject to the environmental impact assessment. Now, the waste water discharged from the regular phosphorus trichloride production enterprises is extremely low. Therefore, this industry does not have much problem in environmental protection. The main concern is safety. The two raw materials of phosphorus trichloride, yellow phosphorus and chlorine, are very dangerous. Chlorine gas is highly toxic, yellow phosphorus is flammable, and phosphorus trichloride is highly corrosive and reacts violently with water. As one of the main participants in the drafting of the "Procedure", Chen Yong, chief engineer of Taizhou Fushen Chemical Co., Ltd., interpreted the reporter that the "Procedures" stipulates clearly the operation of phosphorus trichloride in all aspects, such as "operational safety". "The chapter states that in the process of phosphating phosphorus, when adding yellow phosphorus to the drum, the water must be drained from the upper part of the phosphating bath, and then the yellow phosphorus drum should be placed in the phosphorus smelting tank quickly." Phosphorus trichloride is stored and transported. The “Safety†chapter stipulates that large phosphorus tanks or tanks containing phosphorus trichloride should be stored in an amount not to exceed 85% of the volume of the container, and barrel containers should not be used for recycling bins. In addition, the "Procedure" is also accompanied by an informative appendix. It has detailed provisions on how to deal with the emergencies of various types of accidents that occur in the company. It has very good reference and guidance value. The introduction of the "Regulations" can effectively avoid the occurrence of security accidents at the micro level, and at the macro level it will bring about structural adjustment within the industry. According to Yu Hao, chief engineer of the Xuzhou Jianping Chemical Co., Ltd., a unit leader of the phosphorus product collaboration group such as phosphorus trichloride, the process indicators in the "Procedure" can be achieved by ordinary companies, and small companies may have difficulties. In addition, according to the national regulations, all high-risk chemical reactions must use automated control systems that can be cut off urgently to avoid the occurrence of vicious accidents. The Regulations also specify the phosphorus trichloride production facilities in this regard, but some small businesses may Due to investment issues can not be completed. “There are more than 100 phosphorus trichloride production enterprises in China, and their SMEs account for about two-thirds of the total. Some small plants have less safety, less environmental protection, and the management system is not perfect. It is easy to have problems. After the “Regulations†were issued, the relevant The department must supervise and inspect the company in accordance with the above requirements. Some small-sized enterprises that are not in size may be eliminated if they do not meet the requirements.†Wu Jinrong thinks. According to Yu Hao, the current domestic phosphorus trichloride is in a state of overcapacity. In the domestic market, small enterprises may have a certain price advantage, which is a deterrent to enterprises with large safety and environmental protection costs. Eliminating non-standard businesses is good for the entire industry. If the industry wants to move forward, it should not focus on vicious competition in prices, but should concentrate on the development of downstream products such as water treatment agents, polymer additives, pharmaceutical intermediates, and pesticide intermediates, and extend the industrial chain. According to Wu Jinrong, the "Procedure" is in the stage of extensive solicitation, and it needs to be revised, supplemented, and perfected to make it more maneuverable. Yang Linhui also told reporters that the "Procedure" should not only consult the manufacturers, but also consult other areas. For example, in the aspect of transportation and packaging, since the division of labor is very fine, some logistics companies are actually packaging experts and may give better solutions. Now that the production safety technology in the phosphorus trichloride industry is relatively mature, transportation has become a top issue. Therefore, regulations in this area should be more professional.
EYH two-dimensional movement mixer is mainly composed of three parts such as the drum, oscillating frame and machine frame. The drum is installed on the oscillating frame, supported by four rollers and positioned axially by two catch wheels. In the four supporting rollers, the two driving wheels are pulled by the rotation power system to make the drum turn. The oscillating frame is driven by a group of crank rocker mechanism, which is installed on the machine frame. The oscillating frame is supported on the machine frame by the bearing assembly.
Features:
The drum of the EYH two-dimensional movement mixer can carry out two movements simultaneously: one is the rotation of the drum and the other is the oscillation of the drum along with the oscillating frame. While the materials to be mixed carry out rotation, turning and mixing along with the drum, they also make reciprocating mixing movement along with the oscillation of the drum. Under joint action of the two movements, the materials are sufficiently mixed within a short time. The EYH two-dimensional movement mixer is suitable for mixing all powder and granular materials.
