Description
Technical field
The utility model is related to the adsorption-desorption devices and its control method of a kind of exhaust gas.
Background technology
In general, the inlet and outlet of the adsorption-desorption device of exhaust gas are connected with various control valve, the valve of different structure
With different control modes, the valve of different location has different control actions.
Invention content
Purpose of utility model：
Adsorption-desorption efficiency can be improved by providing one kind, and that reduces the idle waiting time surmounts valve adsorption-desorption device.
Technical solution：
It is described in the utility model to surmount valve adsorption-desorption tower, there is adsorption-desorption tower A and adsorption-desorption tower B, separately have
Two groups surmount valve（Every group surmount valve with three combination control sub- valve or similar to the control with three valves
And make-break capacity）.
Every adsorption-desorption tower has exhaust gas entrance（Enter adsorption-desorption tower for exhaust gas）, stripping gas entrance（For stripping gas
Body enters adsorption-desorption tower）, also waste liquid outlet（For the waste liquid outflow formed after desorption）.
One end outlet of first group of surmount valve two sub- valve of absorption respectively connected the useless of two adsorption-desorption towers
Gas entrance, the other end outlet of this two sub- valves of absorption of both ends difference unicom of the sub- valve of another intercommunication；Second group surmounts
One end outlet of two sub- valves of desorption of valve respectively connected the stripping gas entrance of two adsorption-desorption towers, another intercommunication
The other end outlet of this two sub- valves of desorption of both ends difference unicom of sub- valve.
Also there is every tower exhaust gas concentration detecting instrument, two exhaust gas concentration detecting instruments to be connected by concentration signal line
Controller, controller, which is connected by control line and controls every group, surmounts valve, or connects and control each sub- valve.
Judge each self-operating, stopping or exchanging operation time by concentration determination.
Since absorption is to compare for a long time（Such as 11-24 hours）The processing procedure of accumulation, and it is the short time to desorb（Such as
1 hour or so）Several processing procedures.When the attached desorber of traditional double suction is an absorption, another is desorbed.Two
Only carry out in turn, two equipment can not work asynchronously, one work when, another stop it is waiting for a long time, treatment effeciency is low.
Utility model works process：
When absorption, exhaust gas surmounts valve from first group（Or one only adsorbs sub- valve）Pass through first adsorption-desorption tower
Exhaust gas entrance enter adsorption-desorption tower carry out adsorption operation, when second adsorb Analytic Tower regeneration ending when, open its mutually
Lead to sub- valve and another adsorbs sub- valve and is carried out at the same time adsorption operation into second adsorption-desorption tower.
When desorption, stripping gas surmounts valve from second group（Or one only desorbs sub- valve）Pass through first adsorption-desorption
The stripping gas entrance of tower enters adsorption-desorption tower and carries out desorption operation, at the end of the absorption that second adsorbs Analytic Tower, opens
The sub- valve of its intercommunication and another desorb sub- valve and are carried out at the same time desorption operation into second adsorption-desorption tower.
The opening and closing for adsorbing and desorbing sub- valve are after being detected by respective exhaust gas concentration detecting instrument, by controlling
Device judges opportunity, then go to control respectively by control line.
Controller controls first group of sub- valve of the absorption of surmount valve one and first works 1 hour or so, rear to open second
It adsorbs sub- valve to work at the same time again 10-23 hours, is then switched off first absorption sub- valve 1 hour or so, second absorption
Valve works on 1 hour or so；Then controller control, which lives another group of group and surmounts one of valve, desorbs sub- valve working 1 hour
Left and right is closed, and opens second desorption sub- valve working 1 hour or so at this time.And close first desorb sub- valve while or
After person closes 1 hour or so, first sub- valve of absorption starts subjob again, and so cycle carries out, and two adsorption-desorption towers are several
There is no the off-air time, acquisition, which has, to be connected in parallel and have the dual ability to work being connected in series with.
Advantageous effect：
The each tower body of the utility model makes full use of, and reduces dead period.By the design of valve and pipeline, reach one
When adsorption-desorption tower desorbs, the air inlet of the tower is automatically into another tower.When one adsorption-desorption tower absorption, the stripping gas gas of the tower
Automatically into another tower.The utilization ratio of two towers improves by about one time than the treatment effeciency of traditional parallel double tower.And it is logical
The test of over-richness switches, and high degree of automation reduces the error of manual intervention and reduces hand labor intensity.It is suitble to processing
The big Work places of exhausted air quantity use.
