Air compressor is a functional equipment necessary for all kinds of coal chemical processes. It has a direct effect on the volume of compressed gas in coal chemical process, improving gas purity, improving process quality and improving coal chemical production efficiency. In the new era, the coal chemical process is developing towards automation, large-scale and intelligent, which brings special requirements to the application of air compressors. It is necessary to closely follow the requirements of the coal chemical process, scientifically carry out the system design and application design of the air compressor, and obtain the deep application results of the air compressor in the coal chemical process system, through the function enhancement of the compressor, node adjustment and structural optimization. The value of the air compressor in the coalification process has been further improved. While promoting the automation and high efficiency of the coalification process, the practical application and practical production of the compressor are scientifically carried out.
Application of air compressor in coal production process
The air compressor is a key component of the coalification process. The air compressor generally includes core series units such as compression impeller, condenser, seal, rotor, casing and exchanger. It can improve the compression of gas through electric power and power. The purpose and role of gas purity, improving coal chemical production efficiency. The air compressors used in the modern coal chemical process production are generally centrifugal air compressors. The centrifugal air compressor rotors have system stability. It is modernized by effectively integrating the low vibration and smooth running performance of the air compressor. Coal chemical process and intelligent coal chemical production are the most important gas compression equipment.
The centrifugal air compressor is based on the high-efficiency and small-flow basic technology of the impeller secondary flow control technology and the impeller and returnor coupling design technology, which greatly improves the function and efficiency of the air compressor, and optimizes the basic links of the coal chemical process. The compression efficiency associated with coal chemical plants has increased by more than 4%. At the same time, the centrifugal air compressor also has a series of advantages such as high temperature resistance, corrosion resistance and low leakage, which satisfies the needs of high temperature and corrosion in the production of coal chemical process. Through the use of centrifugal air compressor, not only can the coal chemical process be optimized. The basic structure has also achieved a 40% reduction in the cost of coal chemical processes. The high-strength, high-stress-resistant corrosive impeller material and the special structure of the closed narrow-channel three-element impeller under strong confinement conditions strengthen and guarantee the function and operation of the centrifugal air compressor, satisfying the impeller material in the coal chemical process production. Strength requirements and service life requirements in a hydrogen sulfide corrosion environment. In the structure of the centrifugal air compressor, there is a nickel-base alloy material resistant to high temperature and solid particle scouring, and a boronizing technology is applied to the surface of the main compression core portion, which not only greatly improves the service life of the air compressor, but also realizes The overall technical scheme of the centrifugal air compressor unit for large-scale coal chemical plant is optimized and designed and manufactured, which improves the efficiency of the coal chemical process and further improves the output and efficiency of the coal chemical industry.
