Chemical Equipment, a general term for machines and equipment used in the chemical industry. In chemical production, in order to process raw materials into finished products of certain specifications, a series of chemical processes such as raw material pretreatment, chemical reaction and separation and refining of reaction products are often required. The machinery used to realize these processes is often classified as chemical equipment. .
According to Yubo Zhiye Market Research Center, chemical equipment can usually be divided into two categories:
1 chemical machine. Refers to the main moving parts of the moving machinery, such as various filters, crushers, centrifugal separators, rotary kiln, mixers, rotary dryers and fluid conveying machinery.
2 chemical equipment. Refers to machines whose main active parts are stationary or have little movement, such as various containers (tanks, tanks, kettles, etc.), ordinary kiln, towers, reactors, heat exchangers, ordinary dryers, evaporators, reactors , electrolysis tank, crystallization equipment, mass transfer equipment, adsorption equipment, fluidization equipment, common separation equipment and ion exchange equipment.
The division of chemical machinery is not strict. Some fluid transport machinery (such as pumps, fans and compressors) are often referred to as chemical machinery in the chemical industry, but at the same time they are general machinery in various industrial production. In addition to relying on the development of mechanical engineering and materials engineering, the design and manufacture of modern chemical equipment is closely related to the development of chemical engineering and chemical engineering.
The quality, output and cost of chemical products depend to a large extent on the perfection of chemical equipment. The characteristics of chemical machinery itself must be able to adapt to the high temperature, high pressure, high vacuum, ultra low pressure and easy often encountered in chemical processes. Special conditions such as burning, explosive and strong corrosive. Modern chemical industry requires chemical machinery: 1 has the safety and reliability of continuous operation. 2 Under sufficient operating conditions (such as temperature, pressure, etc.) have sufficient mechanical strength. 3 has excellent corrosion resistance. 4 good sealing. 5 high efficiency and low energy consumption.
