It is as a kind of important petrochemical materials, for producing synthesis ammonia, methanol and the hydrogenation of petroleum refining process.
The production decision of hydrogen mainly has：Light hydrocarbon steam reforming hydrogen manufacturing technique, coal industries, methanol decomposition hydrogen manufacturing work
Skill and using pressure-variable adsorption method directly from all kinds of hydrogen-containing gas, including various refinery dry gas, reform hydrogen, conversion gas,
The technique such as separating-purifying hydrogen in synthesis gas etc..And hydrocarbon steam reforming hydrogen manufacturing technique, coal industries, methanol decomposition hydrogen manufacturing work
The hydrogen of the preparations such as skill needs also exist for carrying out separating-purifying hydrogen by the method for pressure-variable adsorption, obtains high-purity hydrogen, therefore, becomes
Press Adsorption Hydrogen technology quite extensive in petroleum chemical industry application.
It is the processing step that traditional PSA rinses flow hydrogen manufacturing referring to Fig. 1, the yield of hydrogen is not very high, and device
Investment and operating cost are high.
Due to the importance of hydrogen, therefore as needed, improving the yield of hydrogen in pressure swing adsorption hydrogen production technology has weight
The meaning wanted.
Utility model content
The purpose of this utility model be overcome the deficiencies in the prior art there is provided it is a kind of be more conducive to improve hydrogen yield VPSA
Hydrogen production device is carried, to solve the problem of hydrogen loss is larger in conventional flush regenerative process, it can be reduced by improving hydrogen yield
The production cost of hydrogen, realizes good benefit.
Above-mentioned purpose is realized, a kind of VPSA for improving hydrogen yield is designed and carries hydrogen production device, it is characterised in that：Some adsorption towers
Tower top branch pipe divide two-way respectively, some tower top branch pipes are parallel on product hydrogen manifold all the way；Some tower top branch pipes it is another
On the branch pipe for being parallel to product hydrogen manifold all the way；The bottom of towe of some adsorption towers divides three, the bottom of towe one of some adsorption towers respectively
Branch is parallel on charging house steward, and another branch of bottom of towe of some adsorption towers is parallel on stripping gas gathering tube, stripping gas gathering tube
Outlet be connected with stripping gas surge tank；The another branch of the bottom of towe of some adsorption towers collects the rear entrance with corresponding vavuum pump
Connection, vacuum pump outlet is connected on stripping gas house steward, and the outlet of stripping gas house steward is connected with stripping gas blending tank.
Described vavuum pump is at least provided with two.
The utility model compared with prior art, using the regeneration vacuumized, can improve hydrogen yield 5%~
10%, while the change that the change of meeting generation device investment, public work are consumed while hydrogen output is improved, this practicality is new
Type is about 0.1~0.3 yuan/Nm than the cost of the hydrogen of conventional flush flow fecund3, the cost of voluminous hydrogen will be far below biography
System rinses the hydrogen cost of flow, therefore the utility model is rational；It is new using this practicality when hydrogen-containing gas pressure is relatively low
Type, can save feed gas compressor, you can reduction plant investment and operating cost.

Connection.
Further, described vavuum pump is at least provided with two.
Referring to Fig. 2, wherein all kinds of hydrogeneous unstripped gas pass through the related program-controlled valve connected to the bottom of towe of adsorption tower and work
After skill pipeline enter adsorption tower, from adsorption tower bottom of towe by loaded in adsorption tower it is adsorbent bed after, from the tower top of adsorption tower
Discharge, by sending out battery limit (BL) after related process pipeline and related program-controlled valve and regulating valve voltage stabilizing, adsorption tower realizes all kinds of
The continuous separation of hydrogen-containing gas.
Using the present apparatus extract hydrogen yield can than traditional method for extracting hydrogen shown in Fig. 1 high income 5~10%.
