Waste gas recycling system in hydrogen production

Abstract

The invention discloses a waste gas recycling system in hydrogen production. The system includes a box body, one side of the box body is fixedly connected with an air inlet pipe, a pressure gauge is mounted at the top of the air inlet pipe; the pressure gauge runs through the box body fixedly, an isolation device is arranged above the pressure gauge, the isolation device is arranged in the box body, one side of the isolation device is fixedly connected with a winding device, the winding device is mounted on the box body, a guide rail is fixedly connected to the inner wall of the box body abovethe isolation device, a membrane separator is clamped in the guide rail in a sliding manner, a through hole is formed in the box body on one side of the membrane separator away from the guide rail, amoving device is arranged in the through hole, the moving device is mounted on the box body, so that waste gas is utilized more fully, resource waste is reduced, income is increased, use by customersis facilitated, the membrane separator can be replaced quickly, meanwhile, pollution caused by waste gas leakage is avoided, thus being more environmentally friendly, the system is easy to operate, high in creativity and convenient to use and popularize.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a waste gas recycling system in hydrogen production. Background technique [0002] A variety of waste gases are produced during hydrogen production, among which there is waste hydrogen in the waste gas. At present, waste hydrogen recovery technologies include low temperature separation, temperature swing adsorption, pressure swing adsorption separation, gas membrane separation technology and metal hydride separation technology. [0003] In the prior art, most of the waste hydrogen generated in hydrogen production is not recycled, and a few recycling equipment is complicated to operate and the recovery rate is low, which leads to waste of resources, which in turn affects revenue. Hydrogen recovery equipment through membrane separators, membrane separators The replacement steps are relatively cumbersome, and the waste gas leakage during the replacement is likely to cau...

Problems solved by technology

[0003] In the prior art, most of the waste hydrogen generated in hydrogen production is not recycled, and a few recycling equipment is complicated to operate and the recovery rate is low, which leads to waste of resources, which in turn affects revenue. Hydrogen recovery equipment through membrane separators, membrane separators The replacement steps are relatively cumbersome, and the waste gas leakage during the replacement is likely to cause pollution, which in turn pollutes the environment. In the prior art, the operation is complicated, the invention is weak, and it is not easy to popularize and use. Therefore, we propose a waste gas recovery treatment in hydrogen production The recycling system is used to solve the above problems
