Description
Technical field
The utility model relates to a kind of device that waste gas is handled, and relates in particular to a kind of to waste gas adsorbs, desorption is handled absorber.
Background technology
At present, in the process to the industrial gas emission processing, adopt absorber that organic exhaust gas is adsorbed and the desorption processing more; And adsorber structure commonly used roughly comprises tank body, places the adsorbent bed in the tank body, and adsorbent bed generally is made up of charcoal layer support and the NACF that is filled on the charcoal layer support, is provided with air inlet pipe and exhaust outlet in the tank body outside; Organic exhaust gas in air inlet pipe enters into tank body after; Through adsorbent bed, organic exhaust gas carried out adsorption treatment after, waste gas is discharged by exhaust outlet; Stay the organic impurities on the adsorbent bed, behind the desorption of the steam of process air inlet pipe entering or other organic gas, discharge to carry out follow-up recycling by exhaust outlet again with steam or other organic gas.
In said structure, because adsorbent bed is individual layer, the waste gas absorption that air inlet pipe is got into and the adsorption rate and the desorption rate of desorption are lower; Required adsorption time and desorption time are longer; Operating efficiency is low, if increase work efficiency, can only adopt the form of two or more absorber parallel connections or series connection; Will certainly increase input, and strengthen floor space.
The utility model content
For solving the deficiency that exists in the prior art, the utility model provides the absorber of a kind of raising to waste gas absorption and desorption treatment effeciency, and it is simple in structure.
For realizing above-mentioned purpose; The absorber of the utility model; Comprise the tank body of hollow, the air inlet pipe that is communicated with tank interior and blast pipe; In tank body, be provided with two adsorbent beds, it is outside that described air inlet pipe is arranged on two tank bodies between the adsorbent bed, is respectively equipped with blast pipe in the tank body outside that deviates from two adsorbent beds.
As the qualification to aforesaid way, described adsorbent bed is made up of charcoal layer support that is fixed on tank interior and the activated carbon granule that is filled on the charcoal layer support.
As the further qualification to aforesaid way, described adsorbent bed laterally arranges.
As the qualification to the utility model, but described air inlet pipe is made up of the exhaust inlet pipe and the desorption gas air inlet pipe of closing control.
As the qualification to the utility model, but described blast pipe is made up of the exhaust pipe and the desorption gas delivery pipe of closing control.
The technical scheme of the utility model adopts the form of double-deck adsorbent bed that waste gas is adsorbed and desorption is handled, higher raising operating efficiency, it is simple in structure.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify:
Fig. 1 is the overall structure sketch map of the utility model.
1, tank body; 2, air inlet pipe; 21, exhaust inlet pipe; 22, desorption gas air inlet pipe; 3, blast pipe; 31, exhaust pipe; 32, desorption gas delivery pipe; 4, adsorbent bed; 41, charcoal layer support; 42, activated carbon granule.
The specific embodiment
By shown in Figure 1; The absorber that relates in the present embodiment; Comprise hollow tank body 1, with the air inlet pipe 2 and the blast pipe 3 of tank body 1 internal communication, wherein, but air inlet pipe 2 is made up of with desorption gas air inlet pipe 22 exhaust inlet pipe 21 of open and close controlling; As on exhaust inlet pipe 21 and desorption gas air inlet pipe 22, being equipped with valve; To realize that in order to make compact overall structure, exhaust inlet pipe 21 can adopt a triple valve to be connected setting with desorption gas air inlet pipe 22 to conducting, the closing control of exhaust inlet pipe 21 and desorption gas air inlet pipe 22; Blast pipe 3 is two; Be separately positioned on the top and the bottom of tank body 1, and each blast pipe 3 is by opening and closing controlled exhaust pipe 31 and desorption gas delivery pipe 32 compositions, as on the pipeline section of exhaust pipe 31 and desorption gas delivery pipe 32, being respectively equipped with valve; To realize conducting and closing control to each pipeline; In like manner, in order to be compact overall structure, exhaust pipe 31 also can adopt a triple valve to be connected setting with desorption gas delivery pipe 32.
Be provided with two adsorbent beds 4 in tank body 1 inside; These two adsorbent beds 4 along the vertical direction spacing of tank body 1, laterally arrange; And two adsorbent beds 4 split the both sides up and down in air inlet pipe 2; Like this, promptly formed between two adsorbent beds 4 and be provided with air inlet pipe 2, and tank body 1 outside that two adsorbent beds 4 deviate from direction is respectively equipped with blast pipe 3.
In use, make exhaust inlet pipe 21 conductings, close desorption gas air inlet pipe 22 and desorption gas delivery pipe 32; Waste gas enters into tank body 1 inside through exhaust inlet pipe 21; At this moment, waste gas has two trends, and the first is upwards adsorbed through the adsorbent bed 4 of top; After adsorbent bed 4 fully adsorbs, discharge by the exhaust pipe that is positioned at tank body 1 top 31; Another trend is that the adsorbent bed 4 through the below adsorbs, and, is discharged by the exhaust pipe that is positioned at tank body 1 bottom 31 fully after the absorption through adsorbent bed 4.Carry out desorption after absorption is accomplished and handle, at this moment, close exhaust inlet pipe 21 and exhaust pipe 31; Open desorption gas air inlet pipe 22 and desorption gas delivery pipe 32, desorption gas (like nitrogen or steam) enters into tank body 1 inside by desorption gas air inlet pipe 22, at this moment; Desorption gas has two trends equally, and the first is through the adsorbent bed 4 of top, adsorbent bed 4 is carried out desorption after; Desorption gas delivery pipe 32 by tank body 1 top is discharged; It two is adsorbent beds 4 through the below, and adsorbent bed 4 is carried out being discharged by the desorption gas floss hole 32 of tank body 1 bottom after desorption handles.
In addition, worth explanation is that the activated carbon granule 42 in the adsorbent bed 4 also can be substituted by the other materials with adsorption function; Like NACF; But,, all belong to the protection domain of the utility model as long as relate to the structure of waste gas being carried out two-way absorption or desorption processing no matter how it is out of shape.
