Description

Technical Field

[0001] The utility model relates to the technical field of organic waste gas treatment, in particular to an organic waste gas absorption tower. Background Art

[0002] Organic waste gas absorption towers are widely used in the field of environmental protection. They are mainly used to treat organic waste gas generated in industrial production processes. Absorption towers can be divided into various types, such as plate towers, bubbling absorption towers, and packed absorption towers. They are widely used in various fields such as electricity, medicine, chemical industry, electrical and electronics, metallurgy, brewing, etc. to treat organic waste gas generated in these industrial processes.

[0003] As disclosed in a Chinese patent: A water-soluble organic waste gas absorption tower, application number: CN202022719052.8, includes a tower body, characterized in that an air inlet pipe is provided at the lower end of the tower body, and an air outlet is provided at the top of the tower body. The tower body is provided with a water circulation device, and the water circulation device is connected to a spray device. The spray device is provided with a rotating device, and the rotating device is connected to a driving device. The absorption tower can drive the spray device to rotate, increase the coverage area of ​​the spray device, and improve the absorption effect of water-soluble organic matter.

[0004] However, in the above technical solution, the organic waste gas sometimes contains some waste gas substances that dissolve more slowly. In the above technical solution, in the process of absorbing the organic waste gas by the adsorbent, the organic waste gas will rise rapidly due to buoyancy after passing into the adsorbent, resulting in a shorter retention time of the organic waste gas in the adsorbent, so that the insoluble organic matter in the waste gas cannot be completely absorbed by the absorbent due to insufficient time. At the same time, the organic waste gas usually gathers together and floats up after passing into the adsorbent, so that the contact between the spray device and the organic waste gas is limited, thereby reducing the absorption effect. Utility Model Content

[0005] The main purpose of the present utility model is to provide an organic waste gas absorption tower, which can effectively solve the problem in the background technology that the organic waste gas sometimes contains some waste gas substances that dissolve slowly. In the above technical scheme, in the process of absorbing the organic waste gas by the adsorbent, the organic waste gas will rise rapidly due to buoyancy after passing into the adsorbent, resulting in a shorter retention time of the organic waste gas in the adsorbent, so that the insoluble organic matter in the waste gas cannot be completely absorbed by the absorbent due to insufficient time. At the same time, the organic waste gas usually gathers together and floats up after passing into the adsorbent, so that the contact between the spray device and the organic waste gas is limited, thereby reducing the absorption effect.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An organic waste gas absorption tower comprises a base, an absorption tank is provided on the base, a first partition and an activated carbon adsorption layer are provided in the absorption tank, a spray device is provided between the first partition and the activated carbon adsorption layer, a second partition is provided between the spray device and the first partition, a plurality of air valves are provided on the first partition and the second partition, a plurality of hydraulic rods are fixedly provided on one side below the first partition, an air inlet pipe and an air outlet pipe are provided on one side of the base, two water pumps are provided on the side of the base away from the air inlet pipe, and a central control screen is provided on one side of the base.

[0008] Preferably, the first partition is slidably connected to the base, the second partition is fixedly connected to the base, one side of the hydraulic rod is fixedly connected to the base, the air valve on the first partition is initially in an open state, the air valve on the second partition is initially in a closed state, and the first partition and the second partition are located between two water pumps.

[0009] Preferably, the air valve includes an air valve base, a first through slot is provided on the air valve base, a second through slot is provided above the first through slot, a baffle is provided in the second through slot, a rotating block is provided on the baffle, and a rotating column and a torsion spring are provided on the rotating block.

[0010] Preferably, the diameter of the first through-groove is smaller than the diameter of the second through-groove.

[0011] Preferably, the baffle is rotatably connected to the valve base via a rotating column.

[0012] Preferably, the elastic force of the torsion spring inside the air valve on the first partition plate is greater than the elastic force of the torsion spring inside the air valve on the second partition plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When the utility model is used, the exhaust gas is transported to the absorbent through the air inlet pipe, and then the exhaust gas rises to the first partition, and then the exhaust gas moves between the first partition and the second partition through a number of open air valves on the first partition, and is then blocked by the second partition. At this time, the air valve on the second partition is in a closed state, so the exhaust gas will automatically flatten and adhere to the outer wall surface of the bottom side of the second partition under the action of buoyancy, thereby dispersing the exhaust gas and extending the residence time of the exhaust gas in the absorbent, thereby preventing the insoluble organic matter in the exhaust gas from being completely absorbed by the absorbent due to insufficient time;

[0015] (1) When the present invention is used, as the amount of exhaust gas between the first partition and the second partition increases, the pressure between the first partition and the second partition increases, and then the exhaust gas will gradually increase the force of squeezing the baffle. Since the elastic force of the torsion spring inside the air valve on the first partition is greater than the elastic force of the torsion spring inside the air valve on the second partition, the baffle inside the air valve on the second partition will be pushed open by the exhaust gas, and then the exhaust gas between the first partition and the second partition can move to the activated carbon adsorption layer through the air valve on the second partition, and the exhaust gas flatly attached to the outer wall surface of the bottom side of the second partition is dispersed by using the several air valves on the second partition, thereby increasing the contact area between the exhaust gas and the spray device, thereby improving the absorption effect.

[0020] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2As shown, an organic waste gas absorption tower includes a base 1, an absorption tank 2 is provided on the base 1, a first partition 3 and an activated carbon adsorption layer 4 are provided in the absorption tank 2, a spray device 5 is provided between the first partition 3 and the activated carbon adsorption layer 4, a second partition 6 is provided between the spray device 5 and the first partition 3, a plurality of air valves 7 are provided on the first partition 3 and the second partition 6, a plurality of hydraulic rods 8 are fixedly provided on one side below the first partition 3, an air inlet pipe 9 and an air outlet pipe 10 are provided on one side of the base 1, two water pumps 11 are provided on the side of the base 1 away from the air inlet pipe 9, and a central control screen 12 is provided on one side of the base 1.

[0022] like Figure 3 As shown, in another embodiment of the present invention, the air valve 7 includes an air valve base 701, a first through slot 702 is provided on the air valve base 701, a second through slot 703 is provided above the first through slot 702, a baffle 704 is provided in the second through slot 703, a rotating block 705 is provided on the baffle 704, and a rotating column 706 and a torsion spring 707 are provided on the rotating block 705;

[0023] When it is necessary to open or close the air valve 7, the air or water flow squeezes the baffle 704, and the baffle 704 drives the rotating block 705 to move, so that the baffle 704 and the rotating block 705 rotate around the center of the rotating column 706, and the torsion spring 707 is deformed. When the baffle 704 no longer fits the inner wall of the second through groove 703 close to the first through groove 702, the air valve 7 is in the open state. At this time, air or water can be transported to the corresponding position through the first through groove 702 and the second through groove 703. When the baffle 704 and the second through groove 703 fit the inner wall close to the first through groove 702, the air valve 7 is in the closed state. At this time, air or water cannot be transported to the corresponding position through the first through groove 702 and the second through groove 703. When the air or water flow no longer squeezes the baffle 704, the torsion spring 707 rebounds, causing the air valve 7 to return to its original state.

[0024] The working principle of this organic waste gas absorption tower:

[0025] During use, the absorbent is first injected into the bottom of the absorption tank 2 so that the absorbent submerges the second partition 6, and then the exhaust gas is transported to the absorbent through the air inlet pipe 9, and the spray device 5 is started to spray the absorbent. Then the exhaust gas rises to the first partition 3, and then the exhaust gas moves between the first partition 3 and the second partition 6 through several open air valves 7 on the first partition 3, and is then blocked by the second partition 6. At this time, the air valve 7 on the second partition 6 is in a closed state. Therefore, the exhaust gas will automatically flatten and adhere to the outer wall surface of the bottom side of the second partition 6 under the action of buoyancy, dispersing the exhaust gas and prolonging the retention time of the exhaust gas in the absorbent to prevent the insoluble organic matter in the exhaust gas from being completely absorbed by the absorbent due to insufficient time;

[0026] As the amount of exhaust gas between the first baffle 3 and the second baffle 6 increases, the pressure between the first baffle 3 and the second baffle 6 increases, and then the exhaust gas will gradually increase the force of squeezing the baffle 704. Since the elastic force of the torsion spring 707 inside the air valve 7 on the first baffle 3 is greater than the elastic force of the torsion spring 707 inside the air valve 7 on the second baffle 6, the baffle 704 inside the air valve 7 on the second baffle 6 will be pushed open by the exhaust gas, so that the air valve 7 on the second baffle 6 is in an open state. Then the exhaust gas between the first baffle 3 and the second baffle 6 can move to the activated carbon adsorption layer 4 through the air valve 7 on the second baffle 6, and use the several air valves 7 on the second baffle 6 to disperse the exhaust gas flatly attached to the outer wall surface of the bottom side of the second baffle 6, increase the contact area between the exhaust gas and the spray device 5, thereby improving the absorption effect, and finally the exhaust gas is finally adsorbed by the activated carbon adsorption layer 4, and then the absorbed exhaust gas is discharged to the designated position through the outlet pipe 10.

[0027] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
