(Summary description)With the rapid development of the chemical industry, chemical pollution has become more and more serious, which has brought great damage to the global ecological balance and began to endanger the survival of human beings. How to comprehensively prevent and control chemical pollution has become one of the most prominent problems in today's society. The development of the chemical industry cannot be stopped because of pollution problems, nor can the pollution problems be ignored because of the achievements of the chemical industry. With the use of powder pneumatic conveying equipment in the chemical industry, the emission and pollution problems have been greatly alleviated.   Most raw materials, semi-finished products and products in the chemical industry are powders and granular materials, viscous materials and hot materials. With the automation of the production process, fully sealed pneumatic conveying equipment is the most ideal material conveying equipment. For the pneumatic conveying of chemical raw materials, it is necessary to first understand the physical and chemical properties of the materials to be conveyed, understand the process equipment and equipment performance before and after pneumatic conveying, understand the working conditions set by the factory, and then determine whether pneumatic conveying can be used, and finally determine the equipment The basic technical parameters and system layout flow chart. Advantages of pneumatic conveying Why is pneumatic conveying the most ideal equipment for material conveying in the chemical industry? Combined with the characteristics and production conditions of the materials transported in the chemical industry, pneumatic conveying has the following advantages: (1) The equipment is completely sealed and transported, no dust leakage, and the working environment is clean; (2) Avoid leakage of toxic and harmful substances and protect the health of on-site workers; (3) Various process requirements can be achieved, such as mixing, crushing, cooling, dust removal, etc.; (4) The pipeline layout is flexible and convenient, can be configured with various equipment, and does not occupy a lot of workshop area and space; (5) It adopts PLC and industrial computer control, with high degree of automation, which can realize centralized automatic control, monitoring and detection of the production process; (6) The equipment has stable performance, reliable operation, modular and detachable structure design, which saves space and is convenient for cleaning;   Problems that must be paid attention to in the design of pneumatic conveying of chemical materials: (1) Prevent impurities from mixing into contaminant materials in the pneumatic conveying system. The air needs to be purified, and the water, oil and dust content in the compressed air must be controlled within a certain range. (2) In order to prevent rusting and mixing of iron and other materials, a magnet iron remover should be installed at the feed port. The conveying pipe shall use stainless steel pipe or aluminum pipe, and the ordinary steel pipe selected under the condition of the process permit shall be subjected to surface derusting treatment. (3) Prevent crushing, abrasion and deformation during material transportation. The choice of pneumatic conveying should use low pressure continuous dense phase conveying as much as possible to ensure the performance of the material. (4) In order to ensure the transportation safety of inflammable and explosive materials, inert gas should be used for circulating transportation. For highly hygroscopic materials, a freeze dryer and air filter can be used, and an air source can be used after treatment. (5) For materials and chemicals with static electricity, attention must be paid to the pneumatic conveying of all parts during the installation process, the conveying pipes, storage hoppers, dust collectors, etc. must be grounded, and the filter material of the dust collector should be made of anti-static materials.
