1. Product Overview: The hydrogen mixing compressor is suitable for multi-component mixed process gas pressurization of hydrogen+nitrogen/argon/carbon monoxide, and the mixed medium is flammable and explosive. The sealed explosion-proof scheme is customized according to the hydrogen content of different proportions, which is suitable for heat treatment and continuous gas supply pressurization cycle of reduction furnace.

2, performance characteristics:

Classified explosion-proof design: the hydrogen volume accounts for 0~90%, and the high-hydrogen model adopts dry gas seal+spark-free motor.

Stable ratio output: built-in pressure stabilizing buffer cavity, the components of the mixed gas will not be separated after pressurization, and the ratio fluctuation is less than 0.3%.

Hydrogen embrittlement protection: cylinder block and pipeline are made of austenitic stainless steel with hydrogen embrittlement resistance, so there is no risk of material cracking under long-term high-pressure conditions.

Waste heat recovery: the waste heat recovery of interstage cooling water is supplied to the front-end heating furnace, and the comprehensive energy consumption of the whole process is reduced by 22%.

3. Application scope: bright annealing heat treatment of metal, powder metallurgy reduction sintering, protective gas for glass hot working, gas supply for fuel cell test bench, and gas phase reduction process of special materials.
