Chemical Equipment (ChemicalEquipment), the general term for machinery and equipment used in the production of the chemical industry. In order to process raw materials into finished products of certain specifications in chemical production, a series of chemical processes such as raw material pretreatment, chemical reactions, and separation and purification of reaction products are often required. The machinery used to realize these processes are often classified as chemical equipment. . Chemical equipment is usually divided into two categories: ① Chemical dynamic equipment is chemical machinery. Refers to machinery whose main function is moving, such as various filters, crushers, centrifugal separators, rotary kilns, mixers, rotary dryers, and fluid conveying machinery. ②Chemical static equipment. Refers to machinery whose main functioning parts are stationary or have little movement, such as various containers (tanks, tanks, kettles, etc.), ordinary kilns, towers, reactors, heat exchangers, ordinary dryers, evaporators, reactors , Electrolyzer, crystallization equipment, mass transfer equipment, adsorption equipment, fluidization equipment, ordinary separation equipment and ion exchange equipment, etc. Commonly used in chemical production equipment are: compressors, fans, pumps, mixers, centrifuges, cranes, various conveyors; electric valves.
