(Summary description)Pneumatic conveying systems are widely used in all walks of life, especially in the chemical industry, where most of the raw materials and products are powdery and granular materials, viscous materials, etc. The fully enclosed pneumatic conveying system is an ideal material transportation method. The use of pneumatic conveying systems in the chemical industry has many advantages. For example, the pipeline arrangement can be flexibly adjusted with the plant structure; the closed conveying method can avoid the incorporation of sundries and material overflow; it can fulfill the automation requirements of various processes, such as mixing, grading, Dust removal, etc.; the workshop area and space occupied is small; the production process can be automatically controlled, monitored, and detected intelligently, etc.   So, in the chemical industry, if you want to choose a pneumatic conveying system, what problems should you pay attention to? (1) Materials and chemicals with static electricity are common in the chemical industry. For such materials, when designing a pneumatic conveying system, attention should be paid to the anti-static treatment of each part of the system. When necessary, equipment such as conveying pipes, hoppers, and dust collectors should be Grounding should be done. (2) In the chemical industry, some processes have higher requirements on the quality of materials, and should try to avoid material breakage, wear and deformation during transportation. In addition, when designing the system, the low-pressure dilute-phase pneumatic conveying system should be selected as much as possible to ensure the function of the material.   (3) In order to avoid the mixing of rust and iron and other debris, in the design, it should be considered to install an iron remover at the material inlet. In addition, the conveying pipeline is made of stainless steel pipe or aluminum pipe, or general steel pipe with rust removal treatment on the surface. (4) The transportation of common inflammable and explosive materials in the chemical industry, in order to ensure safety, it is advisable to use inert gas for circulating transportation of such materials. For materials with strong hygroscopicity, the air source can be used after being processed by filtration equipment such as refrigeration dryers and air filters. (5) In order to avoid sundries from being mixed into the polluted materials, the gas source should be cleaned, that is, the water, oil and dust content in the conveyed gas should be controlled within the specified range.   After more than ten years of reserves of large and small projects and the efforts of R&D personnel, Guangzhou Kerishi Technology Co., Ltd. has fully considered the above problems, and equipped special sun protection measures and temperature monitoring in the design of the pneumatic conveying system, and fully considered the temperature control environment of the stored materials. , dry humidity requirements, cutting, cleanliness and other performance parameters and physical and chemical requirements. During the design, a reasonable layout and load-bearing design are made for the on-site material transportation, ease of use, and site conditions.
