Description

Technical Field

[0001] This utility model relates to the field of gas filtration technology, specifically to an acid-containing gas filter. Background Technology

[0002] Acidic gases refer to mixed gases containing acidic components such as sulfuric acid mist, hydrochloric acid mist, and nitric acid mist generated during industrial production processes. They are commonly found in industries such as chemical engineering, metallurgy, electroplating, battery manufacturing, and waste incineration. These gases are highly corrosive, and if they are emitted directly without effective treatment, they will not only severely corrode production equipment and shorten its lifespan, but also pollute the atmospheric environment, causing ecological problems such as acid rain and soil acidification. At the same time, acid mist particles can easily enter the human body through the respiratory tract, and long-term exposure can damage the human respiratory system and mucous membrane tissues, threatening the health of operators.

[0003] Currently, the main technologies for treating acidic gases include wet scrubbing, adsorption filtration, and dry neutralization. Wet scrubbing neutralizes acid mist by spraying alkaline solution, but traditional spraying devices have the problem of uneven spraying range, resulting in low alkaline solution utilization and insufficient reaction, leading to inadequate acid removal. Utility Model Content

[0004] In view of the defects and deficiencies in the existing technology, this utility model provides an acid-containing gas filter.

[0005] To achieve the above objectives, this utility model provides an acid-containing gas filter, which includes a housing. Inside the housing, from left to right, are sequentially arranged an acid removal chamber, a reduction chamber, and a filter chamber. The top of the acid removal chamber is provided with a connecting pipe, which connects the acid removal chamber to the top of the reduction chamber. A partition is provided on one side of the reduction chamber, and multiple connecting ports are provided on the partition. The reduction chamber connects to the filter chamber through these connecting ports. The filter chamber contains a filtration mechanism for filtering air.

[0006] The top of the shell is fixedly connected to a liquid inlet pipe, and the bottom of the liquid inlet pipe is provided with a dispersing mechanism to disperse the acid removal solution.

[0007] One side of the housing is provided with an air inlet pipe and a liquid outlet pipe, both of which are connected to the interior of the acid removal chamber. The other side of the housing is provided with an exhaust pipe that is connected to the filter chamber for discharging gas.

[0008] Preferably, the filtration mechanism includes an alkaline adsorption plate and an activated carbon plate, which are detachably installed sequentially inside the filter chamber. The top of the housing is provided with a rotatable paddle, and there are multiple paddles, which are respectively attached to the top of the alkaline adsorption plate and the activated carbon plate for fixing.

[0009] Preferably, the deceleration chamber has multiple deceleration plates fixedly connected inside, and one end of each deceleration plate has a flange facing upwards to generate turbulence.

[0010] Preferably, the dispersing mechanism includes a connecting pipe and a sleeve. The connecting pipe is fixedly connected to the top wall inside the deacidification chamber and communicates with the liquid inlet pipe. The sleeve is sleeved on the outer surface of the connecting pipe. A nozzle is provided at the bottom of the sleeve.

[0014] Preferably, the diameter of the connecting port increases sequentially upwards along the vertical direction of the partition.

[0015] This utility model provides an acid-containing gas filter, which has the following beneficial effects:

[0016] 1. This utility model provides an acid-containing gas filter. Through the coordinated arrangement of a shell, an acid removal chamber, a reduction chamber, and a filter chamber, acid-containing gas enters from the inlet pipe on one side of the shell and passes through the acid removal chamber, the reduction chamber, and the filter chamber in sequence. The acid mist in the gas is first absorbed by the alkaline solution added in the acid removal chamber. After absorption, the gas enters the reduction chamber, which reduces the flow rate of the gas, thereby improving the absorption effect. After passing through the reduction chamber, the gas enters the filter chamber and undergoes secondary acid removal through the adsorption structure set in the filter chamber, further reducing the acid content in the gas. The overall structure is reasonably designed, and the acid removal chamber, the reduction chamber, and the filter chamber are set in the shell, resulting in a compact structure.

[0017] 2. This utility model, through the combined arrangement of the inlet pipe and the dispersion mechanism, allows the alkaline solution to be transported from the inlet pipe to the dispersion mechanism. The dispersion mechanism then distributes the alkaline solution more evenly within the deacidification chamber, increasing the contact area between the alkaline solution and the acid-containing gas, thereby improving the deacidification efficiency and removing acid mist from the air as much as possible.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Example: Figure 1 and 3 As shown, the acid gas filter of this embodiment includes a housing 1. The housing 1 has an acid removal chamber 2, a deceleration chamber 3 and a filter chamber 4 arranged from left to right inside. The top of the acid removal chamber 2 is provided with a connecting pipe 5, and the acid removal chamber 2 is connected to the top of the deceleration chamber 3 through the connecting pipe 5. A partition 6 is provided on one side of the deceleration chamber 3, and a plurality of connecting ports 7 are provided on the partition 6. The deceleration chamber 3 is connected to the filter chamber 4 through the connecting ports 7. The filter chamber 4 is provided with a filtering mechanism inside for filtering gas.

[0025] A liquid inlet pipe 8 is fixedly connected to the top of the shell 1, and a dispersion mechanism is provided at the bottom of the liquid inlet pipe 8 to disperse the acid removal liquid. An air inlet pipe 9 and a liquid outlet pipe 10 are provided on one side of the shell 1, both of which communicate with the interior of the acid removal chamber 2. The bottom of the acid removal chamber 2 is inclined towards the liquid outlet pipe 10 to facilitate liquid drainage. An exhaust pipe 11 communicating with the filter chamber 4 is provided on the other side of the shell 1 to discharge gas.

[0026] Acid-containing gas enters the housing 1 through the inlet pipe 9 on one side. The inlet pipe 9 extends upward to prevent the alkaline solution in the deacidification chamber 2 from flowing back. The liquid inlet pipe 8 introduces the alkaline solution into the deacidification chamber 2. After contacting the acid-containing air, the alkaline solution neutralizes the acid mist in the air, thus removing the acid. The sprayed alkaline solution flows back out through the drain pipe 10 at the bottom. The alkaline solution with adjusted concentration is then transported back to the liquid inlet pipe 8 by an external water pump or other equipment. The gas neutralized in the deacidification chamber 2 is then transported to the deceleration chamber 3 through the connecting pipe 5 at the top. The deceleration chamber 3 slows down the gas flow rate, allowing the gas to enter the filter chamber 4 more slowly from the connecting port 7. The diameter of the connecting port 7 increases from bottom to top to allow the gas to be more evenly distributed in the filter chamber 4. After secondary filtration by the filtration mechanism, the gas entering the filter chamber 4 is discharged from the exhaust pipe 11 to the next step.

[0027] In this embodiment, see Figure 2 and Figure 3 The filtration mechanism includes an alkaline adsorption plate 12 and an activated carbon plate 13. The alkaline adsorption plate 12 and the activated carbon plate 13 are detachably installed inside the filter chamber 4. The top of the housing 1 is provided with a rotatable lever 14. There are multiple levers 14, which are respectively attached to the top of the alkaline adsorption plate 12 and the activated carbon plate 13 for fixing.

[0028] The gas entering from the deceleration chamber 3 first comes into contact with the alkaline adsorption plate 12, further neutralizing the acidic mist in the air. After being adsorbed by the alkaline adsorption plate 12, it passes through the activated carbon plate 13, which further adsorbs the residual acid mist in the gas, reducing the acid mist content in the gas. Both the alkaline adsorption plate 12 and the activated carbon plate 13 are equipped with sealing rings on their top outer sides to prevent internal gas leakage. After rotating the lever 14 so that the lever 14 is above the alkaline adsorption plate 12 and the activated carbon plate 13, the alkaline adsorption plate 12 and the activated carbon plate 13 can be fixed in the filter chamber 4, preventing them from moving.

[0029] In this embodiment, multiple speed reduction plates 15 are fixedly connected inside the deceleration chamber 3. One end of the speed reduction plate 15 is provided with a flange facing the top to form turbulence. The multiple speed reduction plates 15 are respectively located on both sides of the deceleration chamber 3 and are arranged in an alternating manner.

[0030] Gas flows down from the top and collides with the speed reducer 15. It then moves along the speed reducer 15. The speed reducer 15 has a flange on one side. After the airflow comes into contact with the flange, it moves along the flange. The flange faces upward. The airflow passing through the flange collides with the newly flowing airflow above, thereby forming turbulence to slow down the gas flow rate.

[0031] In this embodiment, see Figure 4The dispersing mechanism includes a connecting pipe 16 and a sleeve 17. The connecting pipe 16 is fixedly connected to the top wall inside the deacidification chamber 2 and communicates with the liquid inlet pipe 8. The sleeve 17 is sleeved on the outer surface of the connecting pipe 16. A nozzle 18 is provided at the bottom of the sleeve 17. A driving mechanism is fixedly connected to the inner wall of the sleeve 17 to drive the sleeve 17 to rotate. The driving mechanism includes a connecting rod 19 and a blade 20. The connecting rod 19 is fixedly connected to the inner wall of the sleeve 17, and the blade 20 is fixedly connected to the top of the connecting rod 19 to drive the sleeve 17 to rotate.

[0032] The inlet pipe 8 delivers the alkaline solution into the connecting pipe 16, which then enters the sleeve 17. The solution is then sprayed out from the nozzle 18 at the bottom of the sleeve 17. The nozzle 18 can form the alkaline solution into a mist, increasing the contact area between the alkaline solution and the air, thereby improving the removal effect of acid mist. During the delivery of the alkaline solution, it collides with the blades 20 inside the sleeve 17, driving the blades 20 to rotate. The rotation of the blades 20 also drives the connecting rod 19 at the bottom to rotate, which in turn drives the sleeve 17 to rotate around the connecting pipe 16. The rotation of the sleeve 17 causes the nozzle 18 connected to the bottom of the sleeve 17 to move, making the area of ​​alkaline solution sprayed by the nozzle 18 more uniform.

[0033] In another preferred embodiment of the present invention, an extension tube 21 is provided inside the deacidification chamber 2. The extension tube 21 is connected to the air inlet pipe 9. The end of the extension tube 21 away from the air inlet pipe 9 is inclined downward. Multiple exhaust holes 22 are provided at the bottom of the extension tube 21.

[0034] The air inlet pipe 9 introduces gas into the extension pipe 21, which extends into the deacidification chamber 2. After passing through the air inlet pipe 9, the gas enters the extension pipe 21 and is discharged from the exhaust port 22 at the bottom of the extension pipe 21. There are multiple exhaust ports 22, which can make the gas more evenly distributed in the deacidification chamber 2.

[0035] In this embodiment, a transparent observation window 23 is provided on the top of the housing 1, and the diameter of the connecting port 7 increases sequentially upward along the vertical direction of the partition 6.

[0036] This invention incorporates an acid removal chamber, a deceleration chamber, and a filter chamber within the housing. Acid-containing gas enters through an inlet pipe on one side of the housing and passes sequentially through these chambers. The acid mist in the gas is first absorbed by the alkaline solution added in the acid removal chamber. After absorption, the gas then enters the deceleration chamber, which reduces the gas flow rate, thereby improving the absorption effect. After passing through the deceleration chamber, the gas enters the filter chamber, where it undergoes secondary acid removal through an adsorption structure, further reducing the acid content in the gas and improving the filtration effect.

[0037] The specific embodiments provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
