Including deoxidation tower, cooling driers, four-way valve, the first cooling tower, the first drying tower, the second cooling tower and second dry connected by pipeline
Dry tower, four-way valve connection pump and surge tank access on front side of the cooling driers, the four-way valve include the first operating position and
Second operating position, when the four-way valve is located at the first operating position, the cooling driers outlet and first cooling tower and institute
The connection of the first drying tower is stated, first drying tower is separately connected finished hydrogen outlet and second cooling tower and described the
Two drying towers, second cooling tower connect the pump；When the four-way valve is located at the second operating position, the cooling driers outlet
It is connected to second cooling tower and second drying tower, second drying tower is separately connected finished hydrogen outlet and institute
The first cooling tower and first drying tower are stated, first cooling tower connects the pump.This kind of hydrogen recovery system is in four-way
When valve is located at first position, the first drying tower is used to absorb the vapor in hydrogen, and the hydrogen by the second drying tower is for blowing
Aqueous vapor is taken on front side of cooling driers and takes away aqueous vapor by cooling driers by dry second drying tower, in the first drying tower saturation or close saturation
When switching four-way valve to the second operating position, the second drying tower is used to absorb the vapor in hydrogen at this time, dry by first
Aqueous vapor is taken on front side of cooling driers for drying up the first drying tower and takes away aqueous vapor by cooling driers, in the second drying tower by the hydrogen of tower
The first operating position is switched back into again when saturation or close saturation, is so recycled, is not needed to be then exhausted from hydrogen, greatly improve hydrogen
Gas produces efficiency.
In above-mentioned technical proposal, it is preferred that be provided with first pressure inspection on rear side of the deoxidation tower of hydrogen flow direction
Survey device.Pressure at this is able to detect using the structure, prevents hypertonia.
In above-mentioned technical proposal, it is preferred that be provided with second pressure detection dress on front side of the pump of hydrogen flow direction
It sets.Pressure at this is able to detect using the structure, prevents hypertonia.
The utility model compared with prior art, has the following beneficial effects: this kind of hydrogen recovery system in four-way valve position
When first position, the first drying tower is used to absorb vapor in hydrogen, by the hydrogen of the second drying tower for drying up the
Aqueous vapor is taken on front side of cooling driers and takes away aqueous vapor by cooling driers by two drying towers, cuts in the first drying tower saturation or close saturation
Four-way valve is changed to the second operating position, the second drying tower is used to absorb the vapor in hydrogen at this time, by the first drying tower
Aqueous vapor is taken on front side of cooling driers for drying up the first drying tower and takes away aqueous vapor by cooling driers by hydrogen, is saturated in the second drying tower
Or it close to the first operating position is switched back into again when being saturated, so recycles, does not need to be then exhausted from hydrogen, greatly improve hydrogen
Produce efficiency.
