Description

Technical Field

[0001] This utility model relates to the technical field of industrial waste gas treatment and dust treatment equipment, specifically a dust separation device based on industrial waste gas treatment. Background Technology

[0002] Industrial waste gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory premises. These waste gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluorides, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead, mercury, beryllium compounds, soot, and industrial dust. When released into the atmosphere, they pollute the air. These substances enter the human body through the respiratory tract via various pathways; some cause direct harm, while others have a cumulative effect, further jeopardizing human health. Different substances have different effects.

[0003] In the process of treating industrial waste gas, dust needs to be separated. Since industrial waste gas contains a lot of harmful substances, traditional separation equipment only performs separation and does not have the function of pre-treatment of harmful dust and gases, which will affect subsequent purification processes. In addition, existing separation equipment mostly uses filter plates for simple separation, resulting in poor cleanliness and reduced efficiency. Based on this, a dust separation device for industrial waste gas treatment is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: a dust separation device based on industrial waste gas treatment, including a tank 1, with a support leg 9 fixedly installed at the bottom of the tank 1, a cyclone separator 12 fixedly installed inside the tank 1, a separator power outlet head 2 connected to the top of the cyclone separator 12, a separator inlet pipe 5 connected to the input end of the top of the cyclone separator 12, and a separator outlet pipe 6 connected to the output end of the separator power outlet head 2. Several outlets are opened inside the bottom end of the separator outlet pipe 6. The bottom end of the cyclone separator 12 is connected to a dust discharge port 14. A dust filter bag 10 is movably fitted onto the outside of the dust discharge port 14, and a clamp 11 is movably fitted onto the outside of the dust filter bag 10. Four separation baffles 18 are fixedly installed on the outside of the cyclone separator 12. The four separation baffles 18 are fixedly installed on the inner wall of the tank body 1 on the outside away from the cyclone separator 12. The tank body 1 and the opposite side of the cyclone separator 12 are separated by the separation baffles 18 to form a first separation chamber 19. A second separation chamber 20 is formed by separating the opposite sides of the cyclone separator 12 through a separation partition 18. A third separation chamber 21 is formed by separating the opposite sides of the tank body 1 and the cyclone separator 12 through a separation partition 18. A fourth separation chamber 22 is formed by separating the opposite sides of the tank body 1 and the cyclone separator 12 through a separation partition 18. The top of the first separation chamber 19 is connected to an annular connecting pipe 1 23. The top of the second separation chamber 20 is connected to an annular connecting pipe 2 15. The top of the third separation chamber 21 is connected to an annular connecting pipe 3 24. The interiors of the first separation chamber 19, the second separation chamber 20, the third separation chamber 21 and the fourth separation chamber 22 are all fixedly installed with perforated corrosion-resistant metal mesh 16. The top of the perforated corrosion-resistant metal mesh 16 is covered with a layer of quartz sand 17. The top of the tank body 1 is fixedly fitted with four connecting guide pipes 3. The top of each of the four connecting guide pipes 3 is movably fitted with a sealing cap 4. The bottom of the tank body 1 is fixedly fitted with four discharge pipes 7. The interiors of each of the four discharge pipes 7 are movably fitted with valves 8.

[0020] The working principle of the above technical solution is as follows: During use, the user connects the separator inlet pipe 5 to the exhaust gas pressurization and discharge channel. The exhaust gas enters the interior of the cyclone separator 12 through the guide of the separator inlet pipe 5. Under the cyclone separation action of the cyclone separator 12, the particulate matter is guided into the interior of the dust bag 10 by the guide of the separator dust discharge port 14. The gas is introduced into the interior of the first separation chamber 19 through the separator outlet pipe 6. It is evenly distributed in the interior of the first separation chamber 19 through the balanced guide of the outlet hole 13. The gas passes through the water in the first separation chamber 19 to intercept particulate matter and adsorb a certain amount of water-soluble exhaust gas. Then, the gas is intercepted and dispersed by the perforated corrosion-resistant metal mesh 16 and the quartz sand layer 17 and passes through the annular connecting pipe. The gas is concentrated and guided into the second separation chamber 20. Inside the second separation chamber 20, an alkaline aqueous solution adsorbs certain acidic particles and gases. Finally, it flows through the second annular connecting pipe 15 into the third separation chamber 21. Inside the third separation chamber 21, an acidic aqueous solution adsorbs certain alkaline particles and gases. Finally, it flows through the third annular connecting pipe 24 into the fourth separation chamber 22. Inside the fourth separation chamber 22, an organic solution adsorbs and intercepts certain organic particles and gases, thus improving filtration and separation, resulting in cleaner exhaust gas, increased separation and filtration efficiency, simple overall structure, convenient maintenance, easier replacement of washing liquid, and improved overall operating efficiency.

[0021] In another implementation scheme, such as Figures 1-4 As shown, the separator power outlet 2 is fixedly inserted through the tank 1 and extends to the top of the tank 1. The top of the cyclone separator 12 is sealed to the top of the inner cavity of the tank 1. The separator air inlet pipe 5 is fixedly inserted through the tank 1 and extends to the outside of the tank 1. The separator dust outlet 14 is fixedly inserted through the tank 1 and extends to the bottom of the tank 1.

[0022] The extension of the separator power outlet 2 facilitates maintenance and liquid diversion. The cyclone separator 12 and the separation baffle 18, together with the tank body 1, divide the interior of the tank body 1 into multiple compartments, which facilitates sealing and makes each separation compartment independent. The separator dust outlet 14 facilitates the discharge of dust separated by the cyclone separator 12.

[0023] In another implementation scheme, such as Figures 1-4 As shown, the tank body 1, the perforated corrosion-resistant metal mesh 16, and the cyclone separator 12 are all made of corrosion-resistant materials.

[0024] All structures in contact with the gas are made of corrosion-resistant materials, which helps to extend the service life. This solution uses airflow circulation to separate the gas in multiple separation chambers, so that the gas is separated and filtered multiple times. Most particulate matter is filtered and separated from most suspended particles and various gaseous impurities in the exhaust gas, which improves efficiency. Furthermore, under the guiding and intercepting effect of the hollowed-out corrosion-resistant metal mesh 16 and the quartz sand layer 17, the gas distribution is more uniform and the liquid and gas contact is uniform. Combined with the guiding effect of the liquid, the interception effect of particulate and microparticle matter is increased, further improving the separation and filtration efficiency.

[0025] In another implementation scheme, such as Figures 1-4 As shown, the end of the separator outlet pipe 6 away from the separator power outlet head 2 is fixedly inserted through the tank body 1 and extends to the bottom of the inner cavity of the tank body 1. The outlet holes 13 are evenly distributed in a circular linear pattern inside the separator outlet pipe 6. The end of the separator outlet pipe 6 away from the separator power outlet head 2 is connected to the inside of the first separation chamber 19. The end of the annular connecting pipe 1 23 away from the first separation chamber 19 is connected to the inside of the second separation chamber 20. The end of the annular connecting pipe 2 15 away from the second separation chamber 20 is connected to the inside of the third separation chamber 21. The end of the annular connecting pipe 3 24 away from the third separation chamber 21 is connected to the inside of the fourth separation chamber 22. The annular connecting pipe 2 15, the annular connecting pipe 1 23 and the annular connecting pipe 3 24 are all L-shaped.

[0026] The gas flows through the separator outlet pipe 6 into the first separation chamber 19, then through the annular connecting pipe 1 23 into the second separation chamber 20, then through the annular connecting pipe 2 15 into the third separation chamber 21, and finally through the annular connecting pipe 3 24 into the fourth separation chamber 22, thus forming an airflow circulation. This facilitates the relative stability of the overall structure. The L-shaped design is used to guide the mixed gas into the liquid and directs the flow to the bottom of the perforated corrosion-resistant metal mesh 16, facilitating stable airflow contact and guidance.

[0027] In another implementation scheme, such as Figures 1-4 As shown, the four connecting guide pipes 3 and the discharge pipe 7 are positioned correspondingly, and the four connecting guide pipes 3 and the discharge pipe 7 are respectively connected to the top and bottom of the first separation chamber 19, the second separation chamber 20, the third separation chamber 21 and the fourth separation chamber 22.

[0028] The connecting guide pipe 3 facilitates the addition of liquid and the discharge of gas. For example, during gas processing, gas can be discharged in a separation zone. An external air pump can be connected to the connecting guide pipe 3 to actively discharge the gas or apply air pressure to extract it, which can improve the efficiency of airflow and change the discharge position of the airflow according to the actual operation requirements, thereby increasing convenience. The discharge pipe 7 facilitates the discharge when changing liquid, making it convenient to replace and discharge liquid, thus facilitating liquid flow.

[0029] In another implementation scheme, such as Figures 1-4 As shown, the first separation chamber 19 contains water, the second separation chamber 20 contains an alkaline aqueous solution, the third separation chamber 21 contains an acidic aqueous solution, and the fourth separation chamber 22 contains an ethanol organic solution.

[0030] Aqueous solutions are the most economical and environmentally friendly, and can meet most separation needs. Other separation liquids are extended solutions to adapt to different waste gas separation and filtration, thus increasing the wider adaptability. For example, alkaline solutions are lime water or ammonia water, acidic solutions are sulfuric acid solutions, and organic solutions are ethanol or propanol. This allows for adjustment and replacement according to process requirements and the composition of waste gas, further increasing the convenience of use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
