煤气压缩机

1. Product Overview: Gas compressor is a kind of volumetric or dynamic gas compression equipment specially used for pressurizing and transporting various industrial gases. Gas is a broad term, which generally refers to combustible gas mixture (such as coke oven gas, blast furnace gas, water gas, producer gas, biogas, etc.) produced by coal gasification, chemical process or fermentation. These gases usually have complex components (including hydrogen, carbon monoxide, methane, nitrogen, etc.), may contain impurities (tar, dust, hydrogen sulfide), and are flammable and explosive. Therefore, the gas compressor is significantly different from the ordinary air compressor in design, material and manufacturing process, and it is necessary to focus on leakage prevention, corrosion prevention, explosion prevention and safety and reliability.

2, performance characteristics:

Leak-proof design: adopt special shaft seal (such as dry gas seal and labyrinth seal), oil-free or oil-less lubrication technology and high-standard static seal to prevent toxic, flammable and explosive gas from leaking out.

Explosion-proof configuration: the motors, electrical instruments and control systems all adopt explosion-proof types that meet the requirements (such as ex d iib t4) to prevent electric sparks from igniting gas.

Anti-impurity ability: the front high-efficiency gas-liquid separator, filter, air inlet valve and other components are designed with anti-scaling and anti-tar adhesion measures. The tolerance of screw compressor to dusty gas is relatively good.

Good regulation performance: the exhaust volume and pressure can be adjusted smoothly in a large range by means of pneumatic regulation and frequency conversion speed regulation to adapt to the changes of downstream processes.

Environmental protection design: emphasize zero leakage or micro leakage to reduce environmental pollution. Some models can adopt oil-free lubrication to avoid the subsequent process or product pollution by lubricating oil. The vibration value of equipment is less than 8 mm/s.

3. Scope of application: Gas compressor is an indispensable "heart" equipment in modern industrial gas system. It is not only a simple supercharging tool, but also a key power equipment with highly specialized design to ensure safe, efficient and long-term stable operation under harsh working conditions. Gas compressor is an indispensable equipment in the field of urban gas and energy in iron and steel metallurgy, chemical industry and coal chemical industry. Its selection needs to be comprehensively decided according to the specific gas composition, pressure demand, flow scale and process characteristics.

4. Standard leakage rate (volume percentage) General model (process gas):

The dynamic leakage rate is less than 0.01% (the industry average is about 0.1%)

High-voltage/high-end models (such as M-type and chemical grade):

Dynamic leakage rate < 0.005%

Comply with ISO 15848-1 Class 3 sealing standard.

Absolute leakage (measured)

Continuous operation for 1000 hours:

External leakage < 0.1ml/h

Far below the general level of the industry (> 1 ml/h)
