In close contact, when the dew point of hydrogen is less than -60 DEG C, produces nano-tungsten powder and be possibly realized.
Tungsten oxide can produce the substantial amounts of hydrogen for being rich in water after hydrogen reducing, and the hydrogen rich in water is needed through supercooling
The hydrogen containing a small amount of water is obtained with dividing after water.
Hydrogen now containing a small amount of water is needed to enter in dehydrating tower to be dehydrated, and molecular sieve is typically filled with dehydrating tower
Or silica gel is absorbed water, dry hydrogen is finally obtained.
Dehydrating tower needs to be regenerated after work a period of time, could absorb water once again.
Hydrogen rich in water obtains the hydrogen containing a small amount of water through supercooling and after dividing water during this, it is necessary to pass through design
Rational technological process can just effectively eliminate the impurity content in hydrogen and the steam effectively in control hydrogen, in order to avoid to follow-up
The service life of dehydrating tower impact.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment 1
Refer to Fig. 1 and 2, a kind of three-level dehydration tungsten oxide reduction tail gas predrainage system provided by the utility model, bag
Include the leaching device 1 being sequentially connected, one-level separator 2, air blower 3, one-level heat exchanger 4, two level separator 5, two level heat
Exchanger 6, three-level separator 7, the shell side of described two-stage heat exchanger 6 are connected with the cooler for supplying coolant media
Group 8, the outlet of described one-level separator 2 is connected with hydrogen make pipe 9.
In the present embodiment, described one-level heat exchanger 4 is cooled down using cooling water, therefore, described one-level heat
Cooling water inlet pipe and cooling water outlet pipe are connected with the shell side of exchanger 4.
The operation principle of the present embodiment is：The reduction furnace of peripheral hardware produces high temperature, high humidity, the hydrogen tail gas of more powder, hydrogen tail
Gas, which is first into leaching device 1, carries out dedusting and preliminary cooling, then by air blower after one-level separator 2 divides water
3 pressurizations are entered in one-level heat exchanger 4 to be cooled using cooling water, is passed through after dividing water then into two level separator 5
Crossing two-stage heat exchanger 6 used cold medium to cross cool brine as crossed cool brine cooling and produced by cooling down unit 8, by two level
Divide water into three-level after the heat exchange of heat exchanger 6, so far can reach 90% dehydrating effect, and without solid impurity in hydrogen, it is pure
Degree is high.
In the present embodiment, the bottom of described leaching device 1 is provided with tank 11, and the top of described leaching device 1 is provided with spray
