Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment technology, specifically to an absorption device for acidic exhaust gas. Background Technology

[0002] Industrial exhaust gases are various pollutant gases emitted into the air during fuel combustion and production processes in factories. These exhaust gases contain carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid, lead, mercury, beryllium compounds, soot, and industrial dust. Therefore, they pollute the air after being released into the atmosphere. These substances can also enter the human body through various pathways, and some substances can directly cause harm, severely jeopardizing human health. In chemical production processes, acidic exhaust gases such as acetic acid and hydrochloric acid are frequently produced. If these acidic exhaust gases are directly released into the air, they will also cause environmental pollution. Therefore, acidic exhaust gases need to be absorbed and treated before emission. To improve the absorption efficiency of acidic exhaust gases, specialized acidic exhaust gas treatment and absorption devices are required to reduce environmental pollution.

[0003] Chinese patent CN217410320U discloses a production exhaust gas absorption and treatment device, relating to the technical field of exhaust gas treatment devices. It includes a housing with a concentration monitor inside. A gas collecting pipe is fixedly connected to one side of the housing, and a test tube is fixedly connected to the other side. One end of a return pipe is fixedly connected to the housing. This invention utilizes the interaction between an extension pipe inside the housing, a rotating shaft fixedly connected to the output end of a first motor, multiple stirring rods fixedly connected to the rotating shaft, and a return pipe fixedly connected to one side of the evaporator to ensure sufficient contact between acidic gas and alkaline liquid, achieving a better treatment effect. While this patent achieves the goal of sufficient contact between acidic gas and alkaline liquid, it does not consider the problem of dust or other particulate impurities in the exhaust gas. After prolonged absorption, if these dust or other particulate impurities are not blocked or treated, they will adhere to the inside of the absorption device, obstructing the air intake and affecting the absorption efficiency of the acidic exhaust gas.

[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] like Figures 1-6 As shown, this embodiment proposes an absorption device for acidic tail gas, including...

[0032] The processing box 1 and the exhaust pipe 2 are located on the top of the processing box 1;

[0033] The circulating filter assembly 5 is located outside the processing box 1.

[0034] The air intake box 3 and the air intake spray assembly 4 are installed on the top of the processing box 1. The air intake box 3 is installed in the air intake box 3 and the processing box 1.

[0035] The flow propulsion assembly 6 is disposed on both sides of the processing box 1;

[0036] The air intake spray assembly 4 includes a water pump 4-1, which is located on the top of the treatment box 1. Both sides of the air intake box 3 are equipped with a hood 4-2, and the surface of the hood 4-2 is provided with several spray holes 4-3. The hood 4-2 is connected to the output end of the water pump 4-1. The top of the treatment box 1 is provided with a dispersion mesh 4-4, which is located inside the treatment box 1. The top of the air intake box 3 is provided with a pipe 4-5, and a filter screen 4-6 is inserted and connected between the pipe 4-5 and the air intake box 3.

[0037] In this embodiment, in order to achieve the effect of filtering and adsorbing the incoming air, an air intake spray assembly 4 is designed. A pipe 4-5 is provided on the top of the air intake box 3, and a filter screen 4-6 is inserted between the pipe 4-5 and the air intake box 3. The filter screen 4-6 is used to filter the incoming dust. A cover 4-2 is provided on both sides of the top of the air intake box 3. Multiple spray holes 4-3 are opened on the surface of the cover 4-2. One side of the air intake box 3 is connected to the water outlet of the water pump 4-1. Water can be injected into the cover 4-2 by the water pump 4-1. The injected water is sprayed inward through the spray holes 4-3, which can cover the incoming gas to achieve the adsorption treatment effect and bring foreign objects into the water in the treatment box 1. A dispersion mesh 4-4 is opened on the top of the treatment box 1 to disperse the sprayed water downward and improve the treatment effect.

[0038] Furthermore, the circulating filter assembly 5 includes a collection cover 5-1, which is disposed on the side surface of the processing box 1 and is connected to the interior of the processing box 1. A circulation pump 5-2 is disposed on the outer surface of the processing box 1. A connecting pipe 5-3 is disposed between the circulation pump 5-2 and the collection cover 5-1. A separation box 5-4 is disposed on the connecting pipe 5-3. Support layers 5-5 are disposed on both sides inside the separation box 5-4. A filter cover 5-6 is inserted between the support layer 5-5 and the separation box 5-4. A sealing cover 5-7 is fixedly connected to the outside of the separation box 5-4 by bolts.

[0039] In this embodiment, in order to achieve the effect of filtering the water in the treatment tank 1, a circulating filter assembly 5 is designed. A collection cover 5-1 is set on the outside of the treatment tank 1 and communicates with the inside. The highest water level in the treatment tank 1 is maintained at the height connected to the collection cover 5-1 and flows continuously into the collection cover 5-1. A circulating pump 5-2 is installed at the bottom of the outside of the treatment tank 1. A connecting pipe 5-3 is connected between the suction end of the circulating pump 5-2 and the collection cover 5-1. The connecting pipe 5-3 guides the water in the collection cover 5-1 downward. A separation tank 5-4 is set on the connecting pipe 5-3. The guided water enters the separation tank 5-4. Support layers 5-5 are set on the upper ends of both sides of the separation tank 5-4. A filter cover 5-6 is inserted between the support layer 5-5 and the separation tank 5-4 to filter the incoming water. The water is then pumped back to the treatment tank 1 by the circulating pump 5-2. A sealing cover 5-7 is fixed to the outside of the separation tank 5-4 with bolts. The sealing cover 5-7 can be opened to clean the filter cover 5-6.

[0040] Furthermore, the propulsion assembly 6 includes a pair of drive motors 6-1, which are mounted on both sides of the processing box 1. The output end of the drive motors 6-1 is provided with a drive shaft 6-2, and one end of the drive shaft 6-2 is provided with an impeller 6-3.

[0041] In this embodiment, in order to achieve the effect of maintaining the flow of water in the treatment tank 1, a flow propulsion component 6 is designed. A drive motor 6-1 is installed on both sides of the treatment tank 1. The output end of the drive motor 6-1 is provided with a drive shaft 6-2 and an impeller 6-3, which can drive the impeller 6-3 to rotate and push the water in the treatment tank 1, so that the water keeps flowing.

[0042] Furthermore, the drive motors 6-1 are located on the outer two sides of the processing box 1, and a pair of drive motors 6-1 are located at the upper and lower ends of the outer two sides of the processing box 1, respectively.

[0043] In this embodiment, by distributing the two drive motors 6-1 vertically, the water inside can flow more effectively.

[0044] Furthermore, the inner surface of the shroud 4-2 has a certain tilt angle, and the spray holes 4-3 spray downwards at an tilt angle.

[0045] In this embodiment, by using an inclined angle, the water sprayed from both sides can be concentrated and sprayed towards the center, resulting in a better spraying effect.

[0046] Furthermore, the filter sections on both sides of the filter cover 5-6 are inclined structural surfaces.

[0047] In this embodiment, the inclined structure on both sides of the filter cover 5-6 can concentrate the filter material downwards, which can prevent the filter material from clogging one position and affecting the filtration efficiency.

[0048] Furthermore, the bottom of the collection cover 5-1 is bent downwards, and the bent part at the bottom of the collection cover 5-1 is an inclined transition structure.

[0049] In this embodiment, by bending downwards and using an inclined transition section, the collection hood 5-1 is lower than the highest water level, which allows foreign objects floating on the water surface to flow into the collection hood 5-1, thereby improving the filtration effect.

[0050] When exhaust gas needs to be treated, the exhaust gas enters through pipe 4-5, and after entering, it is first filtered through filter screen 4-6, and then enters the air intake box 3. At the same time, water pump 4-1 is started to draw water from the treatment box 1 and inject it into the hood 4-2. Then, the water is sprayed outward through spray hole 4-3 to spray the incoming exhaust gas, carrying foreign objects in the exhaust gas into the water in the treatment box 1. During the treatment process, drive motor 6-1 is kept running, and impeller 6-3 continuously pushes the water. The water at the highest level continuously moves the floating foreign objects into the collection hood 5-1, and then filters them through filter screen 5-6 and then discharges them back into the treatment box 1 through circulation pump 5-2 to form a circulation, keeping the water clean. The treated water is discharged outward through exhaust pipe 2.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
