A hydrogen recovering system with two towers comprises two regeneration towers, a raw material hydrogen collection tank, an elution gas-water separating device, a reducing furnace group, a product hydrogen collection tank, wherein the two regeneration towers are connected in series, each regeneration tower is provided with a water-containing hydrogen inlet, a hot hydrogen inlet and a dry hydrogen outlet thereon, and is provided with a molecular sieve for absorbing moisture therein. The hydrogen recovering system is simple in structure, can ensure that two regeneration towers work alternatively, thereby keeping no discontinuity in work, improves production efficiency and meets the demand of the market.
Description
Technical field
The utility model relates to the Tungsten oxide 99.999 reducing process, is specially a kind of double tower hydrogen recovery system.
Background technology
In the Tungsten oxide 99.999 reducing process, need to utilize hydrogen and Tungsten oxide 99.999 to carry out reduction reaction, and in the meantime; have unnecessary hydrogen and overflow, cause unnecessary waste, increased thus production cost; so in industrial scale is produced, very important to the reclaiming clean of excessive response hydrogen.Now, produce tungsten powder and generally use 15 pipe reduction furnaces, but managing reduction furnaces hydrogen out from 15 all is high temperature, can not be recycled directly to 15 stoves and use, thus after passing through water for cooling, the centre entered again the moisture absorption that regenerator column carries out hydrogen, but regenerator column has certain state of saturation, generally just absorption was complete through 24 hours, need to behind moisture drying, could again lead to hydrogen and work on, cause like this production efficiency very low, can not need by satisfying the market.
The utility model content
The technical problem that the utility model solves is to provide a kind of double tower hydrogen recovery system, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The double tower hydrogen recovery system, comprise regenerator column, the raw hydrogen air collector, the drip washing gas and water separator, reduction furnace group, product hydrogen air collector, the quantity of described regenerator column is two and is connected in series, described regenerator column is provided with the aqueous hydrogen gas entrance, hot hydrogen entrance and dry hydrogen outlet, be provided with the molecular sieve that absorbs moisture in the described regenerator column, described regenerator column links to each other with pressure reducer by gate valve, described pressure reducer links to each other with glass rotameter, described glass rotameter is connected on the described raw hydrogen air collector, be connected with Root's blower behind the described raw hydrogen air collector, described Root's blower links to each other with the purifying filtration unit, hydrogen enters described product hydrogen air collector after by described purifying filtration unit, be connected with described reduction furnace group behind the described product hydrogen air collector, be connected with described drip washing gas and water separator after the described reduction furnace group, hydrogen is circulated to again described raw hydrogen air collector after by described drip washing gas and water separator.
In the utility model, described two regenerator column alternations.
Beneficial effect
The utility model is simple in structure, can guarantee two regenerator column alternations, so that the work continuity is carried out, has improved production efficiency, has satisfied the market requirement.
Description of drawings
Fig. 1 is the structure iron of double tower hydrogen recovery system.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the structure iron of double tower hydrogen recovery system, the double tower hydrogen recovery system, comprise regenerator column 1, raw hydrogen air collector 4, drip washing gas and water separator 5, reduction furnace group 6, product hydrogen air collector 9, the quantity of described regenerator column 1 is two and is connected in series, described regenerator column 1 is provided with the aqueous hydrogen gas entrance, hot hydrogen entrance and dry hydrogen outlet, be provided with the molecular sieve that absorbs moisture in the described regenerator column, described regenerator column 1 links to each other with pressure reducer 2 by gate valve, described pressure reducer 2 links to each other with glass rotameter 3, described glass rotameter 3 is connected on the described raw hydrogen air collector 4, be connected with Root's blower 7 behind the described raw hydrogen air collector 4, described Root's blower 7 links to each other with purifying filtration unit 8, hydrogen enters described product hydrogen air collector 9 after by described purifying filtration unit 8, be connected with described reduction furnace group 6 behind the described product hydrogen air collector 9, be connected with described drip washing gas and water separator 5 after the described reduction furnace group 6, hydrogen is circulated to again described raw hydrogen air collector 4 after by described drip washing gas and water separator 5.
In the utility model, described two regenerator column alternations.When aqueous hydrogen gas enters one of them regenerator column, by molecular sieve the moisture in the hydrogen is absorbed, when the equimolecular sieve absorbs water saturation (regenerator column absorption state of saturation is about 24 hours), this regenerator column just stops the absorption to moisture in the hydrogen, is converted to the logical hot hydrogen of this regenerator column is dried up molecular sieve, meanwhile, another regenerator column begins to pass into the absorption that aqueous hydrogen gas carries out hydrogen moisture, alternate run guarantees working efficiency, so that production technique is uninterruptedly carried out like this.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model; the technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
