Abstract
The utility model relates to a hydrogen producer, concretely relates to device of coking dry gas hydrogen manufacturing, including well change gas storage device (1) and PSA reactor (4), its characterized in that: well change gas storage device (1) and PSA reactor (4) through well changes gas conveying line (2) connection, be provided with control valve (3) on the well change gas conveying line (2), PSA reactor (4) on be provided with hydrogen pipeline (5) and circulation pipeline (6), circulation pipeline (6) be connected with gas circulation device (9). The device has cancelled the cabinet of setting fire among the prior art, has set up gas circulation device on the PSA reactor, has realized that the PSA reactor steps up fast for the speed of production of qualified hydrogen, effective material consumption that reduces when going into operation has reduced environmental pollution and has wasted with the energy.
Description
Technical field
The utility model relates to a kind of hydrogen producer, is specifically related to a kind of device of coking dry gas hydrogen manufacturing.
Background technology
Main containing hydrogen in coking dry gas, carbon monoxide, carbonic acid gas, methane, ethane, ethene, the mixed gass such as propane, and be the prevailing technology that unstripped gas prepares that hydrogen is current hydrogen manufacturing with coking dry gas.First carry out circulation when dry gas hydrogen manufacturing device goes into operation in prior art to heat up, heat up to become in terminating to need after charging to wait gas qualified after just can enter PSA PSA Technology, then the hydrogen of PSA output delivers to hydrogenation use at qualified laggard hydrogen pipe net, the middle change gas that period produces and the hydrogen torch that needs to set fire carrys out exchange system, causes that dry gas hydrogen manufacturing device on-stream time is longer and material waste is serious.
Summary of the invention
Many weak points that the utility model exists for existing coking dry gas device for producing hydrogen, provide a kind of brand-new coking dry gas device for producing hydrogen, this device eliminates cabinet of setting fire of the prior art, PSA reactor is provided with gas-recycling plant, after adopting this device, become that gas is qualified just can enter PSA reactor in not needing to wait for, directly can control to become gas during intake valve draws when going into operation and enter PSA reactor, ON cycle device uses as fuel gas after the gas mixture making reaction produce is collected by gas-recycling plant simultaneously, achieve PSA reactor rapid pressure, accelerate the production rate of qualified hydrogen, when effective reduction goes into operation, supplies consumption reduces environmental pollution and energy dissipation.
Concrete technical scheme of the present utility model is:
A kind of device of coking dry gas hydrogen manufacturing, this device comprises middle change gas storing unit and PSA reactor, described middle change gas storing unit is connected by middle change letter shoot road with PSA reactor, described middle change letter shoot road is provided with control valve, described PSA reactor is provided with hydrogen pipeline and circulation line, and described circulation line is connected with gas-recycling plant.
Described gas-recycling plant is also provided with burning pipeline and blowdown piping.
Device due to whole coking dry gas hydrogen manufacturing needs to pass into nitrogen and carries out gas displacement before going into operation, air in whole equipment is discharged, become in when therefore going into operation in gas storing unit and be in fact full of nitrogen, in prior art, this part nitrogen can directly be discharged from cabinet of setting fire, and after adopting this structure of the utility model, direct opening controlling valve can be produced with middle change gas during use and make the air inlet of PSA reactor, close the hydrogen pipeline on PSA reactor simultaneously, open circulation line, become now nitrogen in gas storing unit with harsh become middle change gas enter PSA reactor by middle change letter shoot road, because reactor pressure does not also reach standard, therefore hydrogen partial is only had to generate, thus formation hydrogen, the mixed gas of middle change gas and nitrogen, now these mixed gass continue to enter into gas-recycling plant through circulation line and are stored, due to not outer row, whole equipment internal pressure equilibrium can realize the rapid pressure in PSA reactor, after the hydrogen of PSA reactor output is qualified, hydrogen pipeline can be opened PSA reactor is normally produced hydrogen sent into hydrogenation technique to use, close circulation line simultaneously, the gas mixture collected in gas-recycling plant is sent in roasting kiln and uses as fuel gas, so just for roasting kiln provides certain fuel, achieve the combustible gas part recycling in gas mixture, decrease energy consumption, avoid this part gas mixture directly to burn the environmental pollution and the wasting of resources that bring at cabinet of setting fire simultaneously.
Gas-recycling plant is also provided with burning pipeline and blowdown piping, described burning pipeline is connected with roasting kiln, like this, when needing the gas mixture in gas-recycling plant to discharge use, can be sent in roasting kiln by burning pipeline, reduce the waste of material;
Meanwhile, if whole system internal pressure is excessive in coking dry gas hydrogen production process, also by blowdown piping pressure release, the safe operation of assurance device.
In sum, after adopting the device of this structure, become that gas is qualified just can enter PSA reactor in not needing to wait for, directly can control to become gas during intake valve draws when going into operation and enter PSA reactor, ON cycle device uses as fuel gas after the gas mixture making reaction produce is collected by gas-recycling plant simultaneously, achieve PSA reactor rapid pressure, accelerate the production rate of qualified hydrogen, effectively reduce supplies consumption when going into operation and reduce environmental pollution and energy dissipation.
