What is the chemical machinery
Chemical machinery. Refers to the main parts for the movement of the machine, such as all kinds of filter machine, crusher, centrifugal separator, rotary kiln, mixer, rotary drier and fluid conveying machinery, etc. Chemical equipment. Refers to the main function parts is stationary or only a small movement of the machine, such as all kinds of containers (tank, pot, kettle, etc.), ordinary kiln, a column, reactor, heat exchanger, the common dryer, evaporator, reactor, electrolytic cell, crystallization equipment, mass transfer and adsorption equipment, fluidization, ordinary separation equipment and ion exchange equipment. Chemical machinery division is not strict, and some of the fluid conveying machinery (such as pump, fan and compressor, etc.) in chemical sector is often called chemical machinery, but at the same time they are general machinery in all kinds of industrial production. Modern chemical machinery design and manufacturing, in addition to rely on the development of mechanical engineering and material engineering, is also closely related to the development of chemical technology and chemical engineering.
Chemical products of quality, yield and cost, to a large extent depends on the perfect degree of the chemical machinery, and chemical machinery itself must be able to adapt to the characteristics of chemical process often encounter high temperature and high pressure, high vacuum and low pressure, inflammable, explosive and strong corrosion resistance and other special conditions. The modern chemical industry requires chemical machinery: it has the safety and reliability of continuous operation. The mechanical strength of a certain operating condition (such as temperature, pressure, etc.) is sufficient. Excellent corrosion resistance. The sealing is good. High efficiency and low energy consumption.
Chemical machinery, the general term for machinery and equipment used in the production of chemical industry. In the chemical production in order to raw materials processed into certain specifications of the finished product, often takes raw material pretreatment, chemical reaction and separation of reaction products and refined a series of chemical process, implement these processes used in machinery, are often classified as chemical machinery.
