Detailed implementation manners
[0016] The following is a detailed description of the implementation manners of the present utility model. Examples of the implementation manners are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The implementation manners described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.
[0017] As Figure 1 and Figure 2 shown, an exhaust gas treatment device for an automatic spraying line specifically includes an exhaust gas discharge pipe 1, an exhaust fan 2, and an exhaust gas treatment box 3. A transfer cavity 4 is provided at the connection between the exhaust gas discharge pipe 1 and the exhaust gas treatment box 3. The exhaust fan 2 is arranged in the transfer cavity 4. The exhaust gas discharge pipe 1 is responsible for guiding the exhaust gas generated by the automatic spraying line to the exhaust gas treatment system to ensure that the exhaust gas is not directly discharged into the environment, which is the first step of exhaust gas treatment. The transfer cavity 4 serves as a transition area between the exhaust gas discharge pipe 1 and the exhaust gas treatment box 3, and the exhaust fan 2 is installed to facilitate the smooth flow of exhaust gas and the installation and maintenance of the fan. The exhaust fan 2 provides power to enable the exhaust gas to overcome the pipeline resistance and smoothly enter the exhaust gas treatment box 3 for further treatment, ensuring the continuous and stable flow of the exhaust gas. The exhaust gas flow can be controlled by adjusting the fan speed to adapt to different production requirements. In the exhaust gas treatment box 3, a filter layer 5, an adsorption layer 6, a catalytic oxidation layer 7, a washing cavity 8, and a demister 9 are provided. The filter layer 5 is arranged at the top of the exhaust gas treatment box 3 behind the transfer cavity 4. The adsorption layer 6 is immediately below the filter layer 6. The catalytic oxidation layer 7 is arranged below the filter layer 5. The washing cavity 8 is located below the catalytic oxidation layer 7. A plurality of spray heads 10 are arranged in the washing cavity 8. A demister 9 is arranged on one side of the washing cavity 8. In implementation, the filter layer 5 preliminarily filters large particles and paint mist in the exhaust gas to protect the subsequent treatment equipment from being blocked. The adsorption layer 6 uses adsorption materials such as activated carbon and molecular sieves to adsorb organic substances and odors in the exhaust gas to further purify the exhaust gas. The catalytic oxidation layer 7, under the action of a catalyst, oxidizes and decomposes some organic substances in the exhaust gas into harmless substances such as carbon dioxide and water. The washing cavity 8 contacts the exhaust gas through the sprayed water mist of the spray heads 10 to wash away soluble pollutants such as acid mist and dust in the exhaust gas. The demister 9 removes the water mist carried in the exhaust gas after washing to prevent the water mist from having an adverse impact on subsequent equipment and the environment.
[0018] As Figure 1As shown in the figure, further, a fixing frame 11 is provided outside the exhaust fan 2, and a driving motor 12 is provided on the fixing frame 11. The driving motor 12 is connected to the exhaust fan 2. The fixing frame 11 provides a stable support platform for the exhaust fan 2. Since the exhaust fan will generate certain vibrations during operation, the fixing frame 11 can effectively disperse and absorb these vibrations. A shock-absorbing seat 17 is provided between the fixing frame 11 and the driving motor 12 to ensure the stable operation of the fan, reduce noise and wear caused by vibrations; the driving motor enables the fan to generate sufficient air flow pressure to guide the waste gas from the spraying line to the waste gas treatment system. By adjusting the output power of the driving motor, the air volume and air pressure of the fan can be controlled to meet the waste gas treatment requirements under different production conditions.
[0019] As Figure 2 shown in the figure, further, the filter layer 5 adopts a paint-blocking net 13. The paint-blocking nets 13 are arranged in multiple layers, and an appropriate distance is maintained between each layer; the multiple layers of paint-blocking nets can more effectively capture paint mist, particulate matter and other impurities in the waste gas, preventing these pollutants from entering the subsequent treatment units. An appropriate distance is maintained between each layer of paint-blocking nets to ensure smooth air flow when passing through the filter layer. The appropriate distance can reduce the resistance of the air flow and prevent the paint-blocking net from losing its filtering effect due to blockage.
[0020] As Figure 1 shown in the figure, further, an adsorption material is provided on the adsorption layer 6. The adsorption material is activated carbon and molecular sieve. Activated carbon can efficiently adsorb organic solvents, harmful gases and odors in the waste gas, and the molecular sieve has selective adsorption, with higher efficiency and accuracy when treating specific types of waste gas.
[0021] As Figure 3 shown in the figure, further, one side of the washing chamber 8 is connected to a water pump 15 through a water outlet pipe 14, and one end of the water pump 15 is connected to a spray head 10 through a circulation pipe 16; under the drive of the water pump 15, the spray head 10 sprays the washing liquid (an aqueous solution containing chemical additives) into the washing chamber 8 in the form of mist. When the waste gas passes through the washing chamber, it comes into full contact with the sprayed washing liquid, and the soluble pollutants in the waste gas are absorbed or dissolved by the washing liquid, thereby realizing the washing and purification of the waste gas. The washed washing liquid flows back to the water pump 15 through the water outlet pipe 14, and is then re-transported to the spray head 10 by the water pump through the circulation pipe 16 for recycling.
[0022] As Figure 2 shown in the figure, further, a sound insulation and heat insulation board 18 is provided on the inner wall of the waste gas treatment box 3. The sound insulation and heat insulation board 18 reduces the impact of the noise and temperature inside the waste gas treatment box 3 on the external environment, improves the working environment, reduces noise pollution, and at the same time protects the equipment from high-temperature damage and extends its service life.
[0023] In the specific working process of the waste gas treatment device for the new automatic spraying line, the waste gas generated during the production process of the automatic spraying line is first guided to the waste gas treatment system through the waste gas exhaust pipe 1. The waste gas exhaust pipe 1 ensures that the waste gas is not directly discharged into the environment. After the waste gas reaches the transfer chamber 4, the exhaust fan 2 starts to work. The exhaust fan 2 is driven by the drive motor 12, stably supported by the fixing frame 11, and the vibration and noise are reduced by means of the shock absorber 17. The exhaust fan 2 provides power to enable the waste gas to overcome the pipeline resistance and smoothly enter the waste gas treatment box 3. After the waste gas enters the waste gas treatment box 3, it first passes through the filter layer 5. The filter layer 5 adopts multiple layers of paint blocking nets 13 to effectively capture impurities such as large particles and paint mist in the waste gas, prevent them from entering the subsequent treatment unit, and protect the subsequent equipment from being blocked. The filtered waste gas enters the adsorption layer 6. The adsorption layer 6 uses adsorption materials such as activated carbon and molecular sieves to adsorb organic substances, harmful gases and odors in the waste gas, and further purify the waste gas. The high adsorption capacity of activated carbon and the selective adsorption characteristics of molecular sieves work together. The waste gas after adsorption treatment continues to flow downward and enters the catalytic oxidation layer 7. Under the action of the catalyst, some organic substances in the waste gas are oxidized and decomposed into harmless substances such as carbon dioxide and water, realizing the deep purification of the waste gas. Subsequently, the waste gas enters the washing chamber 8. A plurality of spray heads 10 are provided in the washing chamber 8. Driven by the water pump 15, the washing liquid containing chemical additives is sprayed into the washing chamber in the form of mist. The waste gas is in full contact with the sprayed washing liquid, and soluble pollutants such as acid mist and dust in the waste gas are absorbed or dissolved by the washing liquid, thereby realizing the washing and purification of the waste gas. The washing liquid after washing flows back to the water pump 15 through the water outlet pipe 14 for recycling; the waste gas after washing carries a certain amount of water mist. When passing through the demister 9, the water mist is effectively removed to prevent the water mist from causing adverse effects on the subsequent equipment and the environment. After the above series of treatments, the harmful substances in the waste gas are effectively removed. After reaching the emission standard, it is safely discharged into the atmosphere through the outlet of the waste gas treatment box 3. The entire treatment process can adapt to the waste gas treatment requirements under different production demands by adjusting parameters such as the fan speed and the output power of the drive motor.
