Problems solved by technology
Since the production of each hearth of the closed combustion furnace is intermittent, the supply flow of hydrogen cannot be adjusted according to the actual number of hearths working, and then after some hearths are turned off, the excess hydrogen is discharged into the atmosphere and cannot be recycled.

The invention discloses a hydrogen recycling device. The hydrogen recycling device comprises a hydrogen recycling channel, the air inlet end of the hydrogen recycling channel is connected with the airoutlet end of a closed type furnace, the air inlet end of the closed type furnace is connected with a gas conveying channel, the air outlet end of the hydrogen recycling channel is connected to the gas conveying channel, the gas conveying channel is connected with a magnetic flow limiting valve and a gas flow monitor according to the flow direction of the gas, the hydrogen recycling channel is connected with the position, between the magnetic flow limiting valve and the gas flow monitor, of the gas conveying channel, the signal output end of the gas flow monitor is electrically connected withthe first signal input end of a PLC, a cooling liquid container, a purification device, a pressurizer, a hydrogen storage bottle and a magnetic switch are sequentially connected to the hydrogen recycling channel, and an air pressure monitor is arranged on the hydrogen storage bottle. Redundant hydrogen generated by the closed type furnace is recycled and reused, energy waste is avoided, and the modern energy-saving emission-reducing environment-friendly theory is achieved.
Description
Technical field [0001] The invention relates to a hydrogen recovery device, in particular to a hydrogen recovery and utilization equipment. Background technique [0002] Traditional closed combustion furnaces use nitrogen-hydrogen mixed gas as the protective medium. Compared with nitrogen, hydrogen has the advantages of good thermal conductivity, low density, low dynamic viscosity, and strong reducibility. It has gradually replaced the nitrogen-hydrogen mixed gas as the protective gas. The purity of the hydrogen discharged from the closed furnace is above 98%, and it can be directly used as fuel gas. If it is properly purified and treated, it can be recycled into the closed furnace. Since the production of each stove in a closed furnace is intermittent, the hydrogen supply flow cannot be adjusted according to the actual number of stoves working, which in turn causes some stoves to turn off, and the excess hydrogen is discharged into the atmosphere and cannot be recycled. Based o...
