Description

Technical Field

[0001] The present invention relates to the technical field of leather production waste gas treatment equipment, and specifically relates to a leather production waste gas treatment system. Background Art

[0002] To ensure the environmental safety during leather production, it is often necessary to treat the waste gas generated during leather production. The invention patent with the patent application number CN201710496957.3 discloses a leather-making waste gas treatment system, which partitions the inner area of the purification tower into a liquid-free treatment chamber and a liquid medicine spraying chamber, so that the treatment layer and the liquid medicine spraying area are separated, avoiding the influence of liquid medicine spraying on the treatment layer. The waste gas can be mainly treated in the treatment layer or mainly treated by liquid medicine spraying, and both can be operated according to the actual situation without interference with each other, enabling the system to have more selectivity for waste gas treatment, thus being able to achieve the comprehensive treatment of various waste gases, facilitating the reduction of pollution control costs. A secondary heat exchange tube is provided, which not only further absorbs the heat of the high-temperature waste gas, fully cools the high-temperature waste gas after passing through the two-stage heat exchange tube, but also the heat absorbed by the secondary heat exchange tube is lower than that absorbed by the primary heat exchange tube. The remaining heat of the high-temperature waste gas is recovered to heat the air in the supply pipe. When the heated spraying liquid sprays on the waste gas, it is beneficial to improve the waste gas treatment effect, achieving the temperature control of the high-temperature waste gas and reasonably utilizing the heat of the high-temperature waste gas in the liquid medicine spraying process. The invention patent with the patent application number CN202410085406.8 discloses a leather production waste gas treatment system, which can collect the waste gas generated during leather production and discharge it into the working container through the inlet pipe. The eddy current mechanism is started, and the eddy current mechanism sucks in and rotates the waste gas discharged from the inlet pipe, making the waste gas fully mix with the adsorbent in the eddy current blades. The mixed waste gas can be discharged into the next process through the outlet pipe at the top of the working container, achieving the effect of pre-treating and purifying the waste gas. After the eddy current mechanism works for a long time, the waste gas supply is stopped and steam is connected through the steam pipe. The steam is also sucked in and rotated by the eddy current mechanism and fully mixed with the adsorbent. After the adsorbent is heated, the adsorbed pollutants are discharged into the gas around the eddy current mechanism, realizing the regeneration of the adsorbent and improving the utilization rate of the adsorbent. According to the disclosed technical solutions, when the existing leather production waste gas treatment equipment is in use, on the one hand, during the purification treatment of waste gas, a large amount of solid pollutants are often generated due to the adsorption work, and then subsequent treatment of solid pollutants is required, which is likely to cause solid waste pollution; on the other hand, during the biological purification treatment, due to the high concentration of waste gas, the purification speed of microorganisms is likely to be insufficient, reducing the waste gas treatment efficiency; on the other hand, during the waste gas treatment using microorganisms, it is likely that due to the too high or too low temperature of the waste gas, it is not conducive to ensuring the purification effect of microorganisms.

[0014] Advantages of the present invention compared with the prior art:

[0015] 1. When the waste gas treatment system for leather production is in use, the waste gas generated from leather production is introduced into the tank body. The temperature is detected by the temperature sensor in the tank body and heated by the heating wire. Then, the catalyst is used to make the waste gas from leather production undergo oxidation, decomposition and other reactions through low-temperature catalysis, so that the pollutants in the waste gas react to produce substances such as carbon dioxide, water, nitrogen, etc. The remaining waste gas sequentially passes through the branch pipe, conduit, header pipe and side pipe and is introduced into the bottom of the tower barrel. When the waste gas flows upward at the bottom of the tower barrel, it is absorbed and decomposed by the microorganisms on the packing into carbon dioxide, water, sulfuric acid, nitric acid, etc. The water pump 1 sprays water on the packing through the spray pipe and nozzle to provide the necessary nutrients for the microorganisms, and at the same time takes away the decomposed sulfuric acid and nitric acid to ensure the growth safety of the microorganisms. At the same time, it can extract and utilize sulfuric acid and nitric acid, reduce the generation and pollution of solid waste, reduce the harm to the environment, ensure environmental safety, and effectively provide the equipment required for an advanced environmental protection industry.

[0016] 2. When the waste gas treatment system for leather production is in use, the high-concentration waste gas pollutants are preliminarily decomposed and oxidized by the catalyst in the tank body to reduce the concentration of the pollutants. After the low-concentration waste gas enters the branch pipe, it then enters the inner side of the tower barrel through the conduit, header pipe and side pipe, and the low-concentration waste gas pollutants are degraded by the microorganisms on the packing. The fan 3 in the outlet discharges the purified gas outward to ensure the flow rate of the waste gas, which can not only effectively improve the purification rate of the pollutants in the waste gas, but also improve the purification rate of the pollutants in the waste gas, and ensure the treatment efficiency of the waste gas from leather production.

[0017] 3. When the leather production waste gas treatment system is in use, when the waste gas that has been oxidized and decomposed has a relatively high temperature due to the heating of the heating wire and the heat generated by the reaction, when the waste gas flows inside the conduit in the air box, the first blower generates a suction force on the air box through the air duct, and the air passes through the filter plate and then cools down the conduit. The cooled waste gas enters the header. The air in the cavity is heated by the waste gas, causing the piston to squeeze the second button upward in the sliding sleeve. The second button turns on the motor, and the motor drives the movable plate to move towards the inner side of the sleeve plate through the lead screw, increasing the distance between the movable plate and the inner wall of the air box, increasing the air flow speed. At the same time, the sleeve plate and the movable plate are used to make the air flow back and forth left and right in the air box, ensuring the air flow speed on the outer side of the conduit, and improving the cooling speed of the waste gas in the conduit. If the temperature of the waste gas entering the header is still relatively high, the piston pushes the second button to compress the spring, and then the piston squeezes the first button. The second water pump pumps the water at the bottom of the water tank into the second connecting pipe, and then flows upward inside the conduit through the inner pipe, making the flow direction of the water opposite to the flow direction of the waste gas, thereby improving the cooling effect on the waste gas. The heat-absorbed water enters the top of the water tank through the bottom of the first connecting pipe, then enters the inner side of the card cover through the through holes on the partition plate, and then flows downward along the outer side of the corrugated rod. The second blower blows the air filtered through the filter screen into the inner side of the blowing cylinder through the conical cylinder, and then blows it outward through the air holes on the inner cylinder into the inner side of the water tank. The air flows upward inside the water tank, and the water flows downward along the corrugated rod. The corrugated rod is used to delay the water flow speed and increase the surface area of the water, so as to cool down through the evaporation of the water. The height of the inner cylinder is adjusted by the floating block, increasing the air flow height and preventing the water from entering the inner side of the blowing cylinder, thereby enabling the water to be quickly cooled down. The completely cooled water is pumped into the second connecting pipe again by the second water pump to cool down the waste gas in the conduit. The cooled waste gas is introduced into the tower cylinder for microbial decomposition work, ensuring that the microorganisms are at an appropriate temperature, and being able to use the heat generated by the oxidation and decomposition work of the waste gas in the tank for heat preservation work in winter with relatively low temperatures, thereby ensuring the efficient decomposition work of the microorganisms and the purification efficiency of the waste gas.

During use, the waste gas generated in leather production is introduced into the tank body 1. The temperature is detected by the temperature sensor inside the tank body 1 and heated by the heating wire. Then, the waste gas from leather production is subjected to reactions such as oxidation and decomposition through low-temperature catalysis by the catalyst 3, so that the pollutants in the waste gas react to produce substances such as carbon dioxide, water, and nitrogen. The remaining waste gas sequentially passes through the branch pipe 10, the conduit 12, the header pipe 14, and the side pipe 16 and is introduced into the bottom of the tower cylinder 5. When the waste gas flows upward at the bottom of the tower cylinder 5, it is absorbed and decomposed by the microorganisms on the packing 6 into carbon dioxide, water, sulfuric acid, nitric acid, etc. The water pump one 35 sprays water on the packing 6 through the spray pipe 36 and the spray head 39 to provide the necessary nutrients for the microorganisms and take away the decomposed sulfuric acid and nitric acid at the same time to ensure the growth safety of the microorganisms. At the same time, the sulfuric acid and nitric acid can be extracted and utilized to reduce the generation and pollution of solid waste, reduce the harm to the environment, and ensure environmental safety.It can effectively provide the equipment required for an advanced environmental protection industry.

[0029] In this embodiment, a blowing cylinder 27 is welded to the top of the bottom plate 26. An inner cylinder 28 is clamped inside the blowing cylinder 27. A floating block 29 is adhesively attached to the outer side of the inner cylinder 28. The floating block 29 is located at the top of the blowing cylinder 27. Air holes 30 are formed around the inner cylinder 28. A baffle 31 is welded to the top end of the inner cylinder 28. The bottom end of the blowing cylinder 27 passes through the bottom plate 26 and communicates with the conical cylinder 24. A corrugated rod 32 is welded to the bottom of the partition plate 22. The bottom end of the corrugated rod 32 is welded to the top of the bottom plate 26. The corrugated rod 32 and the blowing cylinder 27 are distributed in a staggered manner inside the water tank 21. A clamping cover 33 is welded to the bottom of the partition plate 22. The clamping cover 33 is sleeved outside the corrugated rod 32. A through hole 34 is formed in the partition plate 22. The top of the partition plate 22 communicates with the clamping cover 33 through the through hole 34. A cavity 41 is welded to the top of the header 14. A sliding sleeve 42 is welded to the top of the cavity 41. A piston 43 is clamped inside the sliding sleeve 42. A button one 44 is welded to the inner wall of the sliding sleeve 42. A button two 45 is installed on one side of the button one 44. The top of the button two 45 is connected to the inner wall of the sliding sleeve 42 through a spring 46. The button two 45 is located at the bottom of the button one 44. The button two 45 is connected to the motor 20 through an electric wire. The button one 44 is connected to the water pump two 40 through an electric wire. When in use, when the temperature of the exhaust gas after oxidation and decomposition is relatively high due to the heating of the heating wire and the heat generated by the reaction, when the exhaust gas flows inside the conduit 12 in the air box 4, the fan one 9 generates suction on the air box 4 through the air duct 8. The air is filtered by the filter plate 7 and then cools down the conduit 12. The cooled exhaust gas enters the header 14. The air in the cavity 41 is heated by the exhaust gas, causing the piston 43 to squeeze the button two 45 upward inside the sliding sleeve 42. The button two 45 turns on the motor 20. The motor 20 drives the movable plate 18 to move inward into the sleeve plate 17 through the lead screw 19, increasing the distance between the movable plate 18 and the inner wall of the air box 4, improving the air flow speed. At the same time, the sleeve plate 17 and the movable plate 18 are used to make the air flow back and forth left and right inside the air box 4, ensuring the air flow speed outside the conduit 12 and improving the cooling speed of the exhaust gas inside the conduit 12. If the temperature of the exhaust gas entering the header 14 is still relatively high, the piston 43 pushes the button two 45 to compress the spring 46, and then the piston 43 squeezes the button one 44. The water pump two 40 pumps the water at the bottom of the water tank 21 into the connecting pipe two 15, and then flows upward inside the conduit 12 through the inner pipe 13, making the flowing direction of the water opposite to that of the exhaust gas, thereby improving the cooling effect on the exhaust gas. The water after absorbing heat enters the top of the water tank 21 through the bottom of the connecting pipe one 11, then enters the inside of the clamping cover 33 through the through hole 34 on the partition plate 22, and then flows downward along the outer side of the corrugated rod 32. The fan two 25 blows the air filtered by the filter screen 23 into the inside of the blowing cylinder 27 through the conical cylinder 24, and then blows it out through the air holes 30 on the inner cylinder 28 into the inside of the water tank 21. The air flows upward inside the water tank 21.Water flows downward along the corrugated rod 32. The corrugated rod 32 is used to slow down the water flow speed and increase the surface area of the water, so as to cool down through the evaporation of the water. The height of the inner cylinder 28 is adjusted by the floating block 29 to increase the flow height of the air flow and prevent water from entering the inside of the blowing cylinder 27, thereby enabling the water to cool down rapidly. The completely cooled water is pumped into the connecting pipe two 15 again by the water pump two 40 to cool down the waste gas in the conduit 12. The cooled waste gas is introduced into the tower cylinder 5 for microbial decomposition work, ensuring that the microorganisms are at an appropriate temperature. And when the temperature is relatively low in winter, the heat generated by the oxidation and decomposition work of the waste gas in the tank body 1 is used for heat preservation work, thereby ensuring the efficient decomposition work of the microorganisms and the purification efficiency of the waste gas.

[0030] The leather production waste gas treatment system provides electrical energy for all electrical equipment through an external power supply. During use, the waste gas generated in leather production is introduced into tank 1. The temperature is detected by the temperature sensor in tank 1 and heated by the heating wire. Then, catalyst 3 is used to cause oxidation, decomposition and other reactions of the waste gas from leather production through low-temperature catalysis, so that the pollutants in the waste gas react to produce substances such as carbon dioxide, water, and nitrogen. The remaining waste gas is successively introduced into the bottom of the tower cylinder 5 through the branch pipe 10, the conduit 12, the header 14 and the side pipe 16. When the waste gas flows upward at the bottom of the tower cylinder 5, it is absorbed and decomposed by the microorganisms on the packing 6 into carbon dioxide, water, sulfuric acid, nitric acid, etc. The water pump 35 sprays water on the packing 6 through the spray pipe 36 and the nozzle 39 to provide the necessary nutrients for the microorganisms, and at the same time takes away the decomposed sulfuric acid and nitric acid to ensure the growth safety of the microorganisms. At the same time, sulfuric acid and nitric acid can be extracted and utilized to reduce the generation and pollution of solid waste, reduce the harm to the environment, ensure environmental safety, and can effectively provide the equipment required for an advanced environmental protection industry. The high-concentration waste gas pollutants are preliminarily decomposed and oxidized by the catalyst 3 in the tank 1 to reduce the concentration of pollutants. After the low-concentration waste gas enters the branch pipe 10, it then enters the inner side of the tower cylinder 5 through the conduit 12, the header 14 and the side pipe 16, and the low-concentration waste gas pollutants are degraded by the microorganisms on the packing 6. The fan 38 in the outlet 37 discharges the purified gas outward to ensure the flow rate of the waste gas, which can not only effectively improve the purification rate of the pollutants in the waste gas, but also improve the purification rate of the pollutants in the waste gas, and ensure the treatment efficiency of the leather production waste gas. When the waste gas after oxidation and decomposition has a high temperature due to the heating of the heating wire and the heat generated by the reaction, when the waste gas flows inside the conduit 12 in the air box 4, the fan 9 generates suction on the air box 4 through the air duct 8. The air is filtered by the filter plate 7 and then cools down the conduit 12. The cooled waste gas enters the header 14. The air in the cavity 41 is heated by the waste gas, so that the piston 43 squeezes the button 45 upward in the sliding sleeve 42. The button 45 turns on the motor 20. The motor 20 drives the movable plate 18 to move towards the inner side of the sleeve plate 17 through the lead screw 19, increasing the distance between the movable plate 18 and the inner wall of the air box 4, improving the air flow rate. At the same time, the sleeve plate 17 and the movable plate 18 are used to make the air flow back and forth left and right in the air box 4 to ensure the air flow rate on the outer side of the conduit 12 and improve the cooling rate of the waste gas in the conduit 12. If the temperature of the waste gas entering the header 14 is still high, the piston 43 pushes the button 45 to compress the spring 46, and then the piston 43 squeezes the button 44. The water pump 40 pumps the water at the bottom of the water tank 21 into the connecting pipe 15, and then flows upward inside the conduit 12 through the inner pipe 13, so that the flow direction of the water is opposite to the flow direction of the waste gas, thereby improving the cooling effect on the waste gas. The water after absorbing heat enters the top of the water tank 21 through the bottom of the connecting pipe 11.Then, the air enters the inner side of the card cover 33 through the through hole 34 on the partition plate 22, and then flows downward along the outer side of the corrugated rod 32. The fan 25 blows the air filtered by the filter screen 23 into the inner side of the blow tube 27 through the cone cylinder 24, and then blows it outward to the inner side of the water tank 21 through the air hole 30 on the inner cylinder 28. The air flows upward on the inner side of the water tank 21, and the water flows downward along the corrugated rod 32. The corrugated rod 32 is used to slow down the water flow speed and increase the surface area of the water so that the water can be cooled by evaporation. The height of the inner cylinder 28 is adjusted by the floating block 29 to increase the temperature. The high airflow height is prevented from entering the inner side of the blow tube 27, so that the water is quickly cooled down. The completely cooled water is pumped into the connecting pipe 15 again through the water pump 2 40 to cool the exhaust gas in the conduit 12. The cooled exhaust gas is passed into the tower 5 for microbial decomposition to ensure that the microorganisms are at a suitable temperature. When the temperature is low in winter, the heat generated by the oxidation and decomposition of the exhaust gas in the tank 1 can be used for heat preservation, thereby ensuring the efficient decomposition of the microorganisms and the purification efficiency of the exhaust gas.
