Description

Technical Field

[0001] This disclosure relates to the field of waste gas treatment equipment technology, and in particular to a waste gas treatment device for cattle slaughterhouses. Background Technology

[0002] In order to prevent the exhaust gases generated during the slaughtering process from drifting and causing air pollution, exhaust gas treatment equipment needs to be installed in cattle slaughterhouses to purify the exhaust gases generated during the slaughtering process and protect environmental safety.

[0003] Patent application CN201610856641.6 discloses a waste gas purification device that uses a spray method to trap particulate matter in the waste gas. This prevents a large number of solid particles from entering the purification body and adhering to the purification components, thus avoiding problems such as poor purification effect. Furthermore, removing these particles effectively improves the purification effect of the low-temperature plasma electric field and ultraviolet lamps, enhancing the purification quality. The device also features a barrier net to trap moisture in the passing waste gas, directing it back to the storage tank along surface guide channels, preventing excessive moisture absorption. The increased water vapor entering the purification unit effectively reduces damage to internal components and minimizes impact on purification quality. The left and right guide plates provide guidance, ensuring smoother gas flow and reducing internal flow resistance. Cooling fins further cool the guide plates. When exhaust gas and water vapor enter and impact the left guide plate, they are rapidly cooled, preventing the liquid from being heated during circulation. This design is perfectly suited for purifying high-temperature flue gas. The fin design increases the contact area, facilitating faster heat transfer and effectively... The increased impact area allows water mist to quickly impact and form larger water droplets, which then flow into the water storage tank, reducing the amount of water mist entering the purification unit. Patent application CN202311304945.8 discloses an ultra-low temperature exhaust gas deep treatment device, including a condensation chamber with multiple spaced condensation plates arranged from top to bottom, dividing the chamber's interior into multiple gas delivery channels for exhaust gas. Scrapers are installed on these channels, fitting snugly against the condensation plates, and have ventilation holes for exhaust gas passage. The device also includes a drive assembly connected to the scrapers. The drive scraper slides along the direction of the exhaust gas flow on the condenser plate, scraping off the sticky solvent adhering to the condenser plate. By setting multiple condenser plates and flushing the condenser plate with cooling medium, the condenser plate cools the exhaust gas, causing the exhaust gas to condense into organic solvents, which then flow to the outlet port along with the inclined condenser plate. By setting scrapers in the gas delivery channel, the scrapers slide on the condenser plate under the drive of the drive component, which can scrape off and discharge the sticky solvent adhering to the condenser plate, thereby eliminating the sticky residue formed by the sticky solvent, allowing the condenser plate to make normal contact with the exhaust gas, ensuring the cooling effect of the condenser plate, and achieving excellent exhaust gas treatment effect.

[0004] According to its publicly available technical solutions, existing waste gas treatment equipment has several drawbacks. First, the slaughtering process of cattle easily generates pollutants such as grease, down, and water mist, which can cause adhesion to filtration or other purification equipment, compromising the safety of the equipment. Second, when absorbing harmful gases from the waste gas, the concentration of the absorption solution gradually decreases, hindering the efficiency of waste gas treatment. Third, it cannot quickly separate impurities generated during waste gas treatment, further compromising the effectiveness of waste gas treatment. Summary of the Invention

[0015] Optionally, the bottom end of the nozzle is bolted to the top of the water pump, and the other end of the nozzle passes through the side wall of the air box and the guide plate in sequence and extends to the bottom of the perforated plate.

[0016] Optionally, a water pipe is welded to the other side of the bellows, one end of which extends to the inside of the bellows. The height of the water pipe is higher than the bottom of the blowpipe. A float valve is installed at the bottom of one end of the water pipe. The float valve is fixed to the inner wall of the bellows via a slide rail. The air duct is welded to the top of the other side of the bellows. The blower is bolted to the inside of the air duct. The air duct is connected to the inside of the bellows.

[0017] The technical solution provided in this disclosure may include the following beneficial effects: The air duct is bolted to the top of the cattle slaughterhouse, and the suction inlets are installed at the top of the slaughtering process where exhaust gases are most likely to be generated. A blower generates suction through the air duct into the bellows. Depending on the workload of the slaughtering process, the rotary valves inside the suction inlets at different locations are adjusted to provide greater suction for the top of processes generating more exhaust gases. Exhaust gases are drawn into the bottom of the bellows through the suction inlets and air duct. As the exhaust gases flow to the left at the bottom of the bellows, the main roller drives the mesh fabric to rotate, supported by the main and auxiliary rollers. The mesh fabric absorbs grease, water mist, and lint from the exhaust gases. During the rotation of the mesh fabric, the absorbed grease and water... The mist and lint are carried between the main roller and the pressure roller. The pressure between the main roller and the pressure roller squeezes out the grease and water, and the water and grease carry away the lint. The grease, water mist and lint adhering to the pressure roller are scraped off by the scraper to the bottom of the air box. The heating wire heats the bottom of the air box to maintain a certain temperature, ensuring that the grease has a certain fluidity so that the grease, water mist and lint can be discharged through the outlet to the inside of the discharge pipe, and then discharged outward through the discharge pipe. This prevents the grease, water mist and lint from adhering to the subsequent waste gas treatment equipment, ensuring the safe operation of the equipment and the effectiveness of waste gas treatment.

[0018] The heat generated by the heating wire raises the temperature of the exhaust gas. The exhaust gas enters the top of the air box through the left side of the guide plate, and then flows downward through the perforated plate. The water pump draws in the exhaust gas absorption liquid, which is then pumped into the nozzle through the spray pipe and atomized and sprayed out through the nozzle. As the exhaust gas flows downward, it comes into contact with the atomized exhaust gas absorption liquid, which falls onto the packing material and wets the surface of the packing. As the exhaust gas flows downward through the gaps in the packing, it comes into contact with the exhaust gas absorption liquid again, so that the exhaust gas absorption liquid can absorb the harmful gases in the exhaust gas. The exhaust gas and exhaust gas absorption liquid fall to the top of the blow plate, and then enter the inner side of the exhaust gas absorption liquid through the blow nozzle and blow pipe in sequence, so as to recover the exhaust gas absorption liquid. At the same time, the exhaust gas enters the inner side of the exhaust gas absorption liquid, which can fully absorb the exhaust gas. The system absorbs harmful gases from the waste gas absorption liquid, preventing residual gases from forming. Gas overflowing from the top of the absorption liquid flows upward through the right side of the side plate and is drawn out from the inside of the duct by the suction of the fan. The heated waste gas improves the reaction efficiency, and the heat increases the evaporation rate of water in the absorption liquid. This allows the water to evaporate while the effective components in the absorption liquid are consumed, thus maintaining the concentration of the absorption liquid. When the amount of absorption liquid decreases, it can be automatically replenished through a water pipe, and the liquid level is controlled by a float valve to prevent the blower from being exposed. This effectively improves the purification efficiency of harmful gases in the waste gas and prevents the purification effect from decreasing due to the reduced concentration of the absorption liquid.

[0019] As the waste gas absorption liquid is continuously consumed by the harmful gases in the waste gas, when the reaction produces insoluble substances, these substances fall directly from the top of the baffle through the connecting pipe to the inside of the filter cartridge. The motor, via a screw plate, scrapes the insoluble substances to the right inside the filter cartridge until they enter the inside of the cone. Then, the screw plate's compression forces the insoluble substances to push open the pressure valve and discharge them outwards. When the reaction produces soluble substances, the effective components in the waste gas absorption liquid are continuously consumed, and the water is continuously evaporated. The continuous replenishment of new waste gas absorption liquid increases the amount of soluble substances produced, leading to the precipitation of these soluble substances due to increased concentration. These precipitated soluble substances are filtered into the inside of the filter cartridge during the circulation process, then pushed to the inside of the cone by the screw plate and discharged outwards. This automatic discharge of the reaction products prevents the accumulation of large amounts of substances inside the equipment, which would affect the purification of the waste gas and thus ensure the treatment effect.

Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, this disclosure proposes an exhaust gas treatment device for a cattle slaughterhouse, comprising: a collection component, an oil removal component, and an absorption component. The collection component includes a wind box 1 and a duct 2. A suction component is installed at the bottom of the duct 2, and the suction component includes a suction port 3 and a rotary valve 4. An exhaust component is installed at the top of the wind box 1, and the exhaust component includes a duct 8 and a fan 9. A flow guiding component is installed inside the wind box 1, and the flow guiding component includes a support plate 16 and a guide plate 17. The oil removal component includes a door panel 5 and a mesh 13. A rotating component is installed inside the mesh 13, and the rotating component includes a main roller 11 and a secondary roller 12. A cleaning component is installed at the bottom of the main roller 11. The system includes a pressure roller 14 and a scraper 15. An oil discharge assembly is installed at the bottom of the door panel 5, comprising a discharge pipe 6 and a discharge port 7. The absorption assembly includes a perforated plate 19 and packing material 20. A support assembly is installed on the packing material 20, comprising a side plate 18 and a blowing plate 21. An air blowing assembly is installed on the blowing plate 21, comprising a blowing port 34 and a blowing pipe 22. A filter assembly is installed at the bottom of the blowing pipe 22, comprising a baffle plate 23 and a filter cartridge 24. A cleaning assembly is installed on the filter cartridge 24, comprising a motor 26 and a screw plate 27. A slag discharge assembly is installed on the filter cartridge 24, comprising a cone 28 and a pressure valve. A spray assembly is installed on one side, including a water pump 29 and a spray pipe 30. A filter cartridge 24 is bolted to the bottom of a partition plate 23. A connecting port is opened at the top of one end of the filter cartridge 24, and a connecting pipe 25 is welded to the top of the connecting port. The filter cartridge 24 is connected to the top of the partition plate 23 via the connecting pipe 25. A conical cylinder 28 is welded to the other end of the filter cartridge 24. The conical cylinder 28 passes through the air box 1 and extends to the outside of the air box 1. A pressure valve is installed on the inner side of the conical cylinder 28. The outer side of a screw plate 27 is respectively clamped onto the inner walls of the filter cartridge 24 and the conical cylinder 28. A motor 26 is bolted to one side of the air box 1. One end of the screw plate 27 passes through the filter cartridge 24 and the guide pipe 30 sequentially via a sealing ring. The inner wall of plate 17 and air box 1 is keyed to the output shaft of motor 26. The water pump 29 is bolted to one side of air box 1. A water pipe is installed on the water pump 29. The water pipe passes through the side wall of air box 1 and is welded to guide plate 17. The water pipe is located at the top of support plate 16. The top of support plate 16 is connected to water pump 29 through water pipe. The bottom end of nozzle 30 is bolted to the top of water pump 29. The other end of nozzle 30 passes through the side wall of air box 1 and guide plate 17 and extends to the bottom of perforated plate 19. A nozzle 31 is installed at the bottom of the other end of nozzle 30. Water pump 29 is connected to nozzle 31 through nozzle 30. Nozzle 31 is located at the top of packing 20.

[0024] Understandably, as the waste gas absorption liquid is continuously consumed by harmful gases in the waste gas, when the reaction produces insoluble substances, these insoluble substances fall directly from the top of the baffle 23 through the connecting pipe 25 into the inner side of the filter cartridge 24. The motor 26 scrapes the insoluble substances to the right inside the filter cartridge 24 via the screw plate 27 until the insoluble substances enter the inner side of the cone 28. Then, the squeezing force of the screw plate 27 causes the insoluble substances to push open the pressure valve and be discharged outwards. When the reaction produces soluble substances, due to the waste gas absorption liquid... The effective components in the solution are continuously consumed, and the water is continuously evaporated. New waste gas absorption liquid is constantly added, which increases the amount of soluble substances produced by the reaction. As a result, the soluble substances produced by the reaction precipitate due to the increased concentration. The precipitated soluble substances are filtered into the inner side of the filter cartridge 24 during the circulation process, and then pushed into the inner side of the cone 28 by the screw plate 27 and discharged outward. This can automatically discharge the substances produced by the reaction outward, avoiding the accumulation of a large amount of substances in the equipment and affecting the purification of waste gas, thereby ensuring the treatment effect of waste gas.

[0025] like Figure 6 , Figure 7 , Figure 10 , Figure 11 and Figure 12As shown, one end of the air duct 2 is installed at the bottom of one side of the air box 1, and an inlet is opened at the top of the other side of the air box 1. The other end of the air duct 2 is installed at the bottom of the other side of the air box 1 by bolts, and the other end of the air duct 2 is connected to the air box 1 through the inlet. The suction port 3 is welded to the bottom of the air duct 2, and the suction ports 3 are evenly distributed at the bottom of the air duct 2. The two ends of the rotary valve 4 are installed on the inner side of the suction port 3 through a rotating shaft. The two sides of the rotary valve 4 are arranged end to end on the inner side of the suction port 3. A driving mechanism is installed on the suction port 3, and the rotary valve 4 rotates on the inner side of the suction port 3 through the driving mechanism. The support plate 16 is welded to the inner wall of the air box 1, and the support plate 16 is located at the top of the inlet. The two ends of the main roller 11, the auxiliary roller 12, and the pressure roller 14 are all installed on the inner side of the air box 1 through rotating shafts. The auxiliary roller 12 is located at the top of the main roller 11. The mesh fabric 1 3 are set on the outer side of the main roller 11 and the auxiliary roller 12. The top of the pressure roller 14 is pressed against the bottom of the mesh fabric 13. The pressure roller 14 is located at the bottom of the main roller 11. The main roller 11, the pressure roller 14 and the auxiliary roller 12 are evenly arranged on the inner side of the wind box 1. The scraper 15 is welded to the inner wall of the bottom of the wind box 1. The top of the scraper 15 is stuck at the bottom of the pressure roller 14. The scraper 15 and the pressure roller 14 correspond one-to-one. The door panel 5 is installed on the inner side of the wind box 1 by bolts.

The outlet 7 and the scraper 15 are alternately distributed at the bottom of the wind box 1. The bottom of the wind box 1 is installed with an electric heating wire 10 by bolts.

[0026] Understandably, the air duct 2 is bolted to the top of the cattle slaughterhouse, and the suction port 3 is installed at the top of the slaughtering process where exhaust gas is easily generated. The blower 9 generates suction force on the air box 1 through the air duct 8. Depending on the workload of the slaughtering process, the rotary valve 4 in the suction port 3 at different positions is adjusted to provide greater suction force for the top of the process that generates more exhaust gas. The exhaust gas is sucked into the bottom of the air box 1 through the suction port 3 and the air duct 2. When the exhaust gas flows to the left at the bottom of the air box 1, the main roller 11 drives the mesh cloth 13 to rotate under the support of the main roller 11 and the auxiliary roller 12. The mesh cloth 13 absorbs grease, water mist, and lint in the exhaust gas. During the rotation, the mesh cloth 13 absorbs... The grease, water mist, and lint are drawn between the main roller 11 and the pressure roller 14. The pressure between the main roller 11 and the pressure roller 14 squeezes out the grease and water, and uses the water and grease to carry away the lint. The grease, water mist, and lint adhering to the pressure roller 14 are scraped off by the scraper 15 to the bottom of the air box 1. The heating wire 10 heats the bottom of the air box 1, keeping the bottom of the air box 1 at a certain temperature to ensure that the grease has a certain fluidity so that the grease, water mist, and lint can be discharged through the outlet 7 to the inside of the discharge pipe 6, and then discharged outward through the discharge pipe 6. This prevents the grease, water mist, and lint from adhering to the subsequent waste gas treatment equipment, ensuring the safe operation of the equipment and the treatment effect of the waste gas.

[0027] like Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 9As shown, the bottom of the guide plate 17 is welded to the top of one side of the support plate 16. The guide plate 17 is installed inside the air box 1 on one side. The side plate 18 is welded to the other side of the air box 1. One side of the perforated plate 19 is welded to the top of the guide plate 17, and the other side of the perforated plate 19 is welded to the side plate 18. The packing 20 is conveniently installed on both sides of the guide plate 17 and the side plate 18 by bolts. There are two packing 20s. One side of the blowing plate 21 is bolted to the guide plate 17, and the other side of the blowing plate 21 is bolted to the bottom of the side plate 18. The blowing port 34 is opened on the blowing plate 21. The top of the blowing pipe 22 is welded to the bottom of the blowing plate 21. The top of the blowing plate 21 is connected to the blowing pipe 22 through the blowing port 34. The partition plate 23... One side of the baffle plate 23 is welded to the guide plate 17, and the other side of the baffle plate 23 is welded to the inner wall of the air box 1. The baffle plate 23 is located at the bottom of the blow pipe 22. Waste gas absorption liquid is installed inside the air box 1 and is installed at the top of the support plate 16. The bottom end of the blow pipe 22 extends to the inside of the waste gas absorption liquid. A water pipe 32 is welded to the other side of the air box 1. One end of the water pipe 32 extends to the inside of the air box 1. The height of the water pipe 32 is higher than the height of the bottom end of the blow pipe 22. A float valve 33 is installed at the bottom of one end of the water pipe 32. The float valve 33 is fixed to the inner wall of the air box 1 by a slide rail. The air duct 8 is welded to the top of the other side of the air box 1. The blower 9 is installed inside the air duct 8 by bolts. The air duct 8 is connected to the inside of the air box 1.

[0028] Understandably, the heat generated by the heating wire 10 raises the temperature of the exhaust gas. The exhaust gas enters the top of the air box 1 through the left side of the guide plate 17, and then flows downward through the perforated plate 19. The water pump 29 draws in the exhaust gas absorption liquid, which is then pumped into the nozzle 31 through the spray pipe 30 and atomized and sprayed out through the nozzle 31. As the exhaust gas flows downward, it comes into contact with the atomized exhaust gas absorption liquid. The exhaust gas absorption liquid falls onto the packing 20 and wets the surface of the packing 20. As the exhaust gas flows downward through the gaps in the packing 20, it comes into contact with the exhaust gas absorption liquid again, so that the exhaust gas absorption liquid can absorb the harmful gases in the exhaust gas. The exhaust gas and exhaust gas absorption liquid fall to the top of the blow plate 21, and then enter the inner side of the exhaust gas absorption liquid through the blow nozzle 34 and the blow pipe 22 in sequence, so as to recover the exhaust gas absorption liquid. At the same time, the exhaust gas is introduced into the exhaust gas absorption. The inner side of the liquid can fully absorb harmful gases in the exhaust gas, avoiding the formation of residual harmful gases. Gas overflowing from the top of the exhaust gas absorption liquid flows upward through the right side of the side plate 18 and is drawn out from the inside of the air duct 8 under the suction of the fan 9. The heated exhaust gas can improve the reaction efficiency, and the heat can increase the evaporation rate of water in the exhaust gas absorption liquid. This allows the water to be evaporated while the effective components in the exhaust gas absorption liquid are consumed, thereby maintaining the concentration of the exhaust gas absorption liquid. When the amount of exhaust gas absorption liquid decreases, it can be automatically replenished through the water pipe 32, and the liquid level is controlled by the float valve 33 to prevent the blow pipe 22 from being exposed. This can effectively improve the purification efficiency of harmful gases in the exhaust gas and prevent the purification effect of the exhaust gas from decreasing due to the decrease in the concentration of the exhaust gas absorption liquid.
