Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment tower equipment, in particular to a high-efficiency and energy-saving industrial waste gas treatment tower. Background Art

[0002] The high-efficiency and energy-saving industrial waste gas treatment tower is an environmentally friendly equipment used to remove harmful gases generated in the industrial production process. Through advanced filtration and adsorption technology, the tower can effectively capture and decompose volatile organic compounds, acidic gases and odorous substances in the waste gas, reducing air pollution. In terms of design, the treatment tower usually adopts a multi-layer structure, combined with different treatment processes such as activated carbon adsorption, biological filter and spray washing to form a linkage effect, significantly improving the waste gas treatment efficiency. At the same time, the equipment is equipped with an intelligent control device that can monitor the waste gas composition and treatment effect in real time, and automatically adjust the working status to achieve optimal energy consumption and treatment effect. In addition, the energy-saving design ensures the rational use of energy in the treatment process, effectively reduces operating costs, and makes it an important solution for modern industrial environmental protection.

[0003] Existing industrial waste gas treatment towers mainly use the method of spraying treatment agents to purify waste gas. This equipment sprays specific treatment agents evenly on the waste gas flow path, prompting harmful components in the waste gas to react with the agents, thereby achieving the purpose of removing pollutants. Treatment agents usually include adsorbents, oxidants or neutralizers. The corresponding agents are selected according to different waste gas components to achieve the best purification effect. In this treatment tower, the waste gas passes through the packing layer and fully contacts the sprayed agent, which enhances the gas-liquid contact area and thus improves the decontamination efficiency. Through reasonable flow control and spraying pressure, the consumption of agents can be effectively reduced and the economy of the device can be improved. In addition, the treated gas undergoes multi-stage filtration and purification to ensure that emissions meet environmental protection standards. This spray treatment tower is widely used in the chemical, petroleum, and pharmaceutical industries, and has become an important means of controlling waste gas emissions.

[0004] However, when purifying waste gas by spraying treatment agents, in actual use, the gas passes through the spraying area at a high speed, so the treatment tower needs to be built too high so that it can be completely purified. Utility Model Content

The outer wall of the air inlet pipe 4 is provided with a heat recovery mechanism 2, which is used to recover and reuse the heat in the exhaust gas.

[0033] Specifically, the liquid treatment box 3 is filled with a large amount of water reagent for treatment. When the industrial waste gas reaches the bubble disk 5 in the liquid treatment box 3 through the air inlet pipe 4, it emerges through the bubble disk 5, thereby performing preliminary treatment on the waste gas. Then the treated waste gas enters the spray tower 9 through the conical air outlet pipe 6 and the discharge ring pipe 7, and is sprayed out through the air nozzle 8. At the same time, by starting the water pump 10, another treatment agent is sucked in through the liquid inlet pipe 11, and introduced into the spray ring pipe 13 through the liquid guide pipe 12, and finally sprayed into the interior of the spray tower 9 through the nozzle 14, so as to further treat the waste gas that has been treated for the first time, and the filtered impurities will be mixed with the sprayed agent and fall to the bottom of the spray tower 9, and finally discharged through the drain pipe 15, thereby reducing operating costs.

A conical rain shield 205 is fixedly connected to the top of the left side of the bow-shaped exhaust pipe 203. A plurality of exhaust ports 206 are opened on the left outer wall of the bow-shaped exhaust pipe 203.

[0035] Specifically, before the exhaust gas enters the liquid treatment box 3 through the air intake pipe 4, its heat will be absorbed by the heat absorption pipe 201, and the heat will be transferred to the bow exhaust pipe 203 through the heat conduction pipe 202.

The human pipe 22 can be easily entered by the staff for cleaning, and the human pipe 22 can be well covered by the pipe cover 23; the outer wall of the liquid guide pipe 12 is provided with multiple limiting rings 24, and the outer wall of the limiting ring 24 is fixedly connected with a fixing column 25, which is fixedly connected to the spray tower 9. The limiting ring 24 and the fixing column 25 can well fix the liquid guide pipe 12 to the outside of the spray tower 9; the front side of the top of the outer wall of the liquid treatment box 3 is connected to a filling port 26, and the top of the outer wall of the filling port 26 is threadedly connected to a water tank cover 27.

[0040] Working principle: Before using the device, first, the liquid treatment box 3 is filled with water reagents for treatment. When the industrial waste gas enters the bubble disk 5 in the liquid treatment box 3 through the air inlet pipe 4, the waste gas will emerge in the form of bubbles through the bubble disk 5, thereby reacting with the treated water reagent and filtering out dust and impurities in the waste gas, thereby achieving preliminary treatment. The treated waste gas then enters the spray tower 9 through the conical outlet pipe 6 and the discharge ring pipe 7, and is sprayed out through the air nozzle 8. At the same time, the water pump 10 is started to suck another treatment reagent into the liquid inlet pipe 11, and is introduced into the spray ring pipe 13 through the liquid guide pipe 12, and finally sprayed into the inside of the spray tower 9 through the nozzle 14, so as to further treat the waste gas. The filtered impurities will be mixed with the sprayed reagent and deposited at the bottom of the spray tower 9 and discharged through the drain pipe 15, thereby reducing operating costs.

[0041] And through the heat recovery mechanism 2, before the exhaust gas enters the liquid treatment box 3, its heat will be absorbed by the heat absorption pipe 201 through the air intake pipe 4, and transferred to the bow exhaust pipe 203 through the heat conduction pipe 202. The bow exhaust pipe 203 is connected to the spray tower 9 through the flange 204, which is convenient for replacement. When the treated exhaust gas enters the bow exhaust pipe 203, it will absorb the transferred heat to ensure that the moisture in the exhaust gas will not remain in the bow exhaust pipe 203 due to cooling, thereby avoiding damage to the bow exhaust pipe 203. The conical rain shield 205 can prevent rainwater from entering the bow exhaust pipe 203 on rainy days, thereby avoiding damage to the bow exhaust pipe 203. Through the heat recovery mechanism 2, energy utilization is improved.
