Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, specifically to an acidic waste gas treatment device for industrial production. Background Technology

[0002] Industrial acidic waste gas mainly originates from the production processes of industries such as chemical, electronics, metallurgy, and electroplating. Its core components are hydrogen chloride (HCl), hydrogen fluoride (HF), sulfuric acid mist (H2SO4), and nitrogen oxides (NOx). x Highly corrosive gases, such as those found in chemical, electronics, metallurgy, and electroplating industries, mainly originate from production processes. Industrial acidic waste gases are complex in composition and highly corrosive, with large concentration fluctuations. Therefore, industrial acidic waste gases need to be neutralized and purified before being emitted. The purification of industrial acidic waste gases is carried out through industrial waste gas treatment equipment. The treatment methods for industrial acidic waste gases include neutralization and adsorption.

[0003] However, when using alkaline solvents to neutralize industrial acidic waste gas, the conveying pipeline needs to be immersed below the surface of the alkaline solvent. This causes the solvent to flow back along the conveying pipeline after the industrial acidic waste gas is stopped, which poses a certain hazard. Therefore, this does not meet the existing requirements. To address this, we propose an acidic waste gas treatment device for industrial production. Utility Model Content

[0004] The purpose of this utility model is to provide an acidic waste gas treatment device for industrial production, so as to solve the problems mentioned in the background art, such as the need for the conveying pipeline to be immersed below the surface of the alkaline solvent when neutralizing industrial acidic waste gas with alkaline solvent, which causes the solvent to flow back along the conveying pipeline after the industrial acidic waste gas is stopped, and the backflow of alkaline solvent poses certain hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an acidic waste gas treatment device for industrial production, comprising a treatment box, a partition fixed inside the treatment box, a neutralization chamber on one side of the partition, an adsorption chamber on the other side of the partition, an inlet pipe fixed through the top of the treatment box, the bottom end of the inlet pipe inserted into the neutralization chamber and fixed with a buffer connecting pipe at the bottom end, a guide connecting pipe fixed at the other end of the buffer connecting pipe, an outlet pipe inserted through one side of the treatment box, one end of the outlet pipe being flush with the inner wall of the adsorption chamber, and an air vent opened at the top of the partition.

[0006] Preferably, an asbestos board is fixed to the inside of the air window, and multiple adsorption filter plates are fixed inside the adsorption chamber.

[0007] Preferably, the adsorption filter plate includes a desiccant plate and an activated carbon plate, which are alternately distributed vertically.

[0008] Preferably, the buffer connecting pipe is V-shaped and has a through return port at the bottom, and a rotating sealing plate is provided below the return port.

[0009] Preferably, the length and width of the rotating sealing sheet are both greater than the length and width of the reflux port.

[0010] Preferably, a rotating connecting plate is fixed to the upper surface of the rotating sealing sheet, and a support rod is inserted through the top of the rotating connecting plate. The two ends of the support rod are rotatably inserted into the buffer connecting tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In this invention, after the industrial acidic waste gas stops being transported and purified, the internal pressure of the inlet pipe, buffer connection pipe, and guide connection pipe decreases. At this time, the alkaline solvent flows back into the inner side of the buffer connection pipe through the guide connection pipe. After entering the buffer connection pipe, the alkaline solvent impacts the rotating connection plate, causing the rotating connection plate to drive the rotating sealing plate support rod to rotate. At this time, the return port opens, and the alkaline solvent that has flowed back into the buffer connection pipe returns to the neutralization chamber, preventing the alkaline solvent from flowing back into the industrial acidic waste gas generating equipment through the pipeline, thereby avoiding damage to the equipment.

[0013] 2. This utility model uses an inlet pipe, a buffer connecting pipe, and a guide connecting pipe to transport industrial acidic waste gas into the alkaline solvent filled at the bottom of the neutralization chamber. The alkaline solvent neutralizes the acidic components in the industrial acidic waste gas, thereby purifying the industrial acidic waste gas and reducing the environmental hazards caused by its discharge.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, an acidic waste gas treatment device for industrial production includes a treatment box 1. A partition 6 is fixed inside the treatment box 1. A neutralization chamber 8 is provided on one side of the partition 6, and an adsorption chamber 9 is provided on the other side of the partition 6. An inlet pipe 3 is fixed through the top of the treatment box 1. The bottom end of the inlet pipe 3 is inserted into the neutralization chamber 8 and a buffer connecting pipe 4 is fixed at the bottom end.

[0021] The buffer connecting pipe 4 is V-shaped and has a through return port 12 at the bottom. A rotating sealing plate 11 is provided below the return port 12. The length and width of the rotating sealing plate 11 are greater than the length and width of the return port 12. The rotating sealing plate 11 is used to seal the return port 12 at the bottom of the buffer connecting pipe 4 to ensure that no acidic waste gas leaves the buffer connecting pipe 4 from the return port 12 during the transportation of industrial acidic waste gas.

[0022] A rotating connecting plate 13 is fixed on the upper surface of the rotating sealing plate 11. A support rod is inserted through the top of the rotating connecting plate 13. The two ends of the support rod are rotatably inserted into the buffer connecting pipe 4. The rotating sealing plate 11 is suspended and supported by the rotating connecting plate 13 to ensure the stability of the position of the rotating sealing plate 11.

[0023] The other end of the buffer connecting pipe 4 is fixed with a guide connecting pipe 5. A discharge pipe 2 is inserted through one side of the treatment box 1. One end of the discharge pipe 2 is flush with the inner wall of the adsorption chamber 9. An air window 7 is opened on the top of the partition 6. The industrial acidic waste gas is transported into the alkaline solvent filled at the bottom of the neutralization chamber 8 through the inlet pipe 3, the buffer connecting pipe 4, and the guide connecting pipe 5. The alkaline solvent is used to neutralize the acidic components in the industrial acidic waste gas, thereby purifying the industrial acidic waste gas and reducing the environmental hazards after the industrial acidic waste gas is discharged.

[0024] An asbestos board is fixed inside the air vent 7, and multiple adsorption filter plates 10 are fixed inside the adsorption chamber 9. The adsorption filter plates 10 include desiccant plates and activated carbon plates, which are distributed alternately. The asbestos board and desiccant plate are used to absorb moisture in the purified waste gas, and the activated carbon plate is used to adsorb residual harmful substances in the purified waste gas.

[0025] Working principle: When treating industrial acidic waste gas, firstly, alkaline solvent for purification is added into the neutralization chamber 8 until the liquid level of the alkaline solvent is close to the rotating sealing plate 11. At this time, the bottom end of the guide connecting pipe 5 is immersed in the alkaline solvent. Then, the industrial acidic waste gas to be purified is transported into the neutralization chamber 8 through the inlet pipe 3. The industrial acidic waste gas enters the alkaline solvent through the inlet pipe 3, buffer connecting pipe 4, and guide connecting pipe 5. After entering the alkaline solvent, the acidic ions of the industrial acidic waste gas react chemically with the alkaline ions in the solvent, thereby changing the acidic ion content inside the industrial acidic waste gas and changing the pH value of the industrial acidic waste gas. The purified industrial waste gas enters the adsorption chamber 9 through the air window 7. The industrial waste gas passes through the adsorption filter plate 10, which adsorbs the moisture and residual harmful substances in the industrial waste gas. Finally, the purified waste gas is discharged out through the discharge pipe 2.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
