Information summary：Chemical Equipment is a general term for machines and equipment used in chemical industry production. In chemical production, in order to process raw materials into finished products of a certain specification, a series of chemical processes such as raw material pretreatment, chemical reaction, and separation and purification of reaction products are often required.
Chemical Equipment is a general term for machines and equipment used in chemical industry production. In chemical production, in order to process raw materials into finished products of a certain specification, a series of chemical processes such as raw material pretreatment, chemical reaction, and separation and purification of reaction products are often required. The machinery used to realize these processes is often classified as chemical equipment. . Chemical equipment can generally be divided into two categories.
1. Chemical machinery. Refers to the machinery whose main action parts are moving, such as various filters, crushers, centrifugal separators, rotary kilns, mixers, rotary dryers and fluid conveying machinery.
2. Chemical equipment. Refers to machinery whose main active parts are static or have only little movement, such as various containers (tanks, tanks, kettles, etc.), ordinary kilns, towers, reactors, heat exchangers, ordinary dryers, evaporators, and reaction furnaces , electrolyzer, crystallization equipment, mass transfer equipment, adsorption equipment, fluidization equipment, common separation equipment and ion exchange equipment, etc.
The division of chemical machinery is not strict, some fluid conveying machinery (such as pumps, fans and compressors, etc.) are often called chemical machinery in the chemical sector, but at the same time they are general machinery in various industrial production. The design and manufacture of modern chemical equipment, in addition to relying on the development of mechanical engineering and material engineering, is also closely related to the development of chemical technology and chemical engineering.
The quality, output and cost of chemical products depend to a large extent on the perfection of chemical equipment, and the characteristics of chemical machinery must be able to adapt to the high temperature, high pressure, high vacuum, ultra-low pressure, easy to Special conditions such as flammable, explosive and highly corrosive. The modern chemical industry requires chemical machinery: ① It has the safety and reliability of continuous operation. ②It has sufficient mechanical strength under certain operating conditions (such as temperature, pressure, etc.). ③It has excellent corrosion resistance. ④Good sealing. ⑤ High efficiency and low energy consumption.
