The utility model discloses a
hydrogen membrane separation device, which realizes double-prevention water removal through the matching action of a water filtering
buffer tank, a U-shaped heater and a separator
buffer tank, and realizes
secondary prevention through the water absorption and compression resistance action of carbon
fiber filler in the water filtering
buffer tank. According to the overheating
protection system, when too much steam enters the U-shaped heater, the temperature of gas is too high, the overheating
protection system controls the steam adjusting valve to adjust the opening degree through the reaction of the process gas filter to reduce air, meanwhile, part of
tail gas is pressurized through the draught fan, and the
tail gas self-adjusting valve is automatically opened to be mixed with process gas to reduce the temperature; under the action of the overheating
system, the film
pipe can be better protected, and the shutdown frequency caused by melting of the film
pipe is avoided; after the starting and stopping times are reduced, the operation and maintenance cost is reduced; and the permeated gas filter filters dust and purely conveys gas to a subsequent
system, so that the dust of the membrane tube entering the subsequent
system is reduced.
