The utility model relates to the technical field of energy conservation and environmental protection, in particular to a device for treating, recycling and reusing acidic wastewater generated in a natural gas hydrogen production device. The steam-water separator comprises a first steam-water separator, a second steam-water separator, a stripping tower and a deaerator, wherein the outlet of the first steam-water separator is connected with the middle water inlet of the stripping tower through a pipeline, the outlet of the second steam-water separator is connected with the upper water inlet of the stripping tower through a pipeline, the top of the stripping tower is provided with a gas outlet, the lower part of the stripping tower is provided with a gas inlet, and the bottom water outlet of the stripping tower is connected with the deaerator through a centrifugal pump. The waste water after the device purifies not only satisfies the direct outer environmental protection requirement of arranging of water, also satisfies the requirement of technology production water simultaneously, and the waste water after will purifying passes through the oxygen-eliminating device and gets into other systems, has not only realized carrying out effective recycle's purpose to waste water, still directly reduces the use amount of demineralized water in the system, has reduced this device production running cost, has alleviateed low reaches sewage treatment system's production pressure.
Description
Technical Field
The utility model relates to the technical field of energy conservation and environmental protection, in particular to a device for treating, recycling and reusing acidic wastewater generated in a natural gas hydrogen production device.
Background
The early natural gas hydrogen production device has low environmental protection requirement, and no special device is used for treating the acidic wastewater generated in the hydrogen production process, so that the wastewater cannot be recycled and is directly discharged to a sewage pipe network, thereby not only causing waste of water energy, but also increasing the load of downstream sewage treatment.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the problems, the utility model provides a wastewater treatment, recycling and reusing device.
The utility model is realized by the following technical scheme: the utility model provides a device is recycled in waste water treatment, its characterized in that, includes catch water separator one, catch water separator two, strip tower and oxygen-eliminating device, the middle part water inlet of pipe connection strip tower is passed through in the export of catch water separator one, and the upper portion water inlet of pipe connection strip tower is passed through in the export of catch water separator two, and the top of strip tower is equipped with the gas outlet, and the lower part of strip tower is equipped with the air inlet, and the oxygen-eliminating device is connected through the centrifugal pump in the bottom delivery port of strip tower.
Preferably, a steam pipeline is arranged at the air inlet, and a steam regulating valve is arranged on the steam pipeline.
Preferably, a water outlet valve is arranged on a pipeline connected with the centrifugal pump and the deaerator.
Preferably, a first drain valve is arranged on a pipeline of the first steam-water separator connected with the water inlet in the middle of the stripping tower, and a second drain valve is arranged on a pipeline of the second steam-water separator connected with the water inlet in the upper part of the stripping tower.
The utility model has the beneficial effects that: the device purifies waste water through the steam in the strip tower, utilizes steam to strip promptly and resolves out the dissolved carbon dioxide in the waste water to realize waste water purification's purpose.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the technical solutions of the present invention are further described below with reference to the following embodiments.
As shown in figure 1, the wastewater treatment recycling device comprises a first steam-water separator 1 and a second steam-water separator 3, strip tower 5 and oxygen-eliminating device 10, the middle part water inlet of pipe connection strip tower 5 is passed through in the export of catch water 1, be equipped with drain valve one 2 on the pipeline of strip tower 5 middle part water inlet is connected to catch water 1, the upper portion water inlet of pipe connection strip tower 5 is passed through in the export of catch water two 3, be equipped with drain valve two 4 on the pipeline of strip tower 5 upper portion water inlet is connected to catch water two 3, the top of strip tower 5 is equipped with the gas outlet, the lower part of strip tower 5 is equipped with the air inlet, air inlet department is equipped with steam conduit 6, be equipped with steam control valve 7 on steam conduit 6, the bottom delivery port of strip tower 5 passes through centrifugal pump 8 and connects oxygen-eliminating device 10, be equipped with outlet valve 9 on the pipeline that centrifugal pump 8 and oxygen-eliminating device 10 are connected.
During the operation, through steam-water separator 1, the acid waste water of two separation gets into strip tower 5 middle part and upper portion respectively through the pipeline, strip tower 5 introduces steam and carries out the strip to waste water and resolve to resolve out carbon dioxide from waste water, the titanium dioxide who resolves out discharges to the atmosphere through the gas outlet, purifies branch waste water and carries to oxygen-eliminating device 10 through centrifugal pump 8, through oxygen-eliminating device 10 entering system, thereby realizes the purpose that this device waste water recovery recycled.
Other technical features than those described in the specification are known to those skilled in the art.
