Description

Technical Field

[0001] This invention relates to a waste gas treatment device for pesticide production, belonging to the technical field of waste gas treatment devices. Background Technology

[0002] The pesticide production process generates a large amount of process waste gas containing dust, colloidal particles and volatile organic pollutants. This type of waste gas has a complex composition, the dust is highly sticky and easily absorbs moisture and caking. If it is directly discharged, it will seriously pollute the surrounding environment. Therefore, it must be treated by professional purification equipment before it can be discharged in compliance with standards.

[0003] Current pesticide exhaust gas treatment equipment relies solely on spray water flow to remove dust. Due to the high viscosity and strong adhesion of pesticide exhaust dust, the dust easily adheres to the inner wall of the tower, the adsorption structure, and the surface of the spray components. Over long-term operation, this dust tends to accumulate, harden, and block the airflow channels and spray holes, leading to a rapid decline in the equipment's purification efficiency. This necessitates frequent shutdowns for disassembly and manual cleaning, resulting in high maintenance requirements and failing to meet the needs of continuous production operations.

[0004] Therefore, there is an urgent need to improve a waste gas treatment device for pesticide production in order to solve the above-mentioned problems. Summary of the Invention

[0011] Preferably, a mixed medicine inlet is fixedly installed above the exhaust gas inlet pipe, a high-pressure sliding component is slidably installed inside the mixed medicine inlet pipe, a second return spring is fixedly connected to the bottom end of the high-pressure sliding component, the other end of the second return spring is fixedly connected to one end of the exhaust gas inlet pipe, a water outlet groove is opened at the top of the high-pressure sliding component, and an annular water curtain nozzle is fixedly installed on the outside of the mixed medicine inlet pipe, the annular water curtain nozzle is located below the water outlet groove.

[0012] Preferably, a baffle plate is fixedly installed on the upper end of the fixing member. The baffle plate is located outside the outlet of the annular water curtain nozzle.

[0013] Preferably, a baffle plate is fixedly installed on the upper end of the fixing member. The baffle plate is located outside the outlet of the annular water curtain nozzle.

[0014] Preferably, a waste ash storage bin is fixedly installed on the outer side of the bottom end of the exhaust gas inlet pipe, and the bottom end and outer side of the waste ash storage bin form a certain air intake gap with the internal space of the device base, so that the gas enters through the bottom end of the waste ash storage bin.

[0015] The present invention has at least the following beneficial effects: 1. This invention uses a tapered copper foil cover with dust adsorption strips to achieve efficient dust collection at the front end. It also utilizes the water pressure of the spray return water to compress the elastic element and store water. The rapid drainage and instantaneous pressure release cause the elastic element to rebound and vibrate, driving the entire tapered copper foil cover to vibrate at high frequency, automatically peeling off the attached pesticide dust. The entire process requires no motor, vibrator or additional power source. It can achieve periodic self-cleaning by relying on the equipment's own water circuit, greatly reducing the frequency of manual maintenance and ensuring that the equipment can maintain smooth flow and purification efficiency for a long time.

[0016] 2. This invention utilizes the combined buoyancy of the airbag and the thrust of the exhaust gas to drive the sliding seat upward to block the air inlet. When the water curtain has not yet formed and the equipment has not reached the purification conditions, the exhaust gas channel is automatically locked to prevent unpurified exhaust gas from overflowing directly. This completely solves the defects of traditional equipment such as gas leakage during startup, instantaneous exceeding of standards, and strong odor in the workshop. The equipment operates in an environmentally friendly and stable manner throughout the entire process.

[0017] 3. The present invention adopts a pressure-adaptive drug feeding structure composed of a high-pressure sliding component and a second reset spring. It can automatically adjust the density of the water curtain according to the exhaust gas concentration and the intake pressure. It automatically increases the spray volume when the air volume is large and automatically throttles the flow when the air volume is small, avoiding the waste of pesticides or insufficient purification caused by fixed spraying. It is suitable for the large fluctuation of pesticide production conditions and has significant energy-saving and consumption-reducing effects.

[0018] 4. The water curtain return water of this invention is divided into two paths. Highly polluted wastewater is directly discharged to avoid deterioration of the circulating water quality. Clean return water enters the water storage tank for use as a power source for vibration cleaning. This realizes graded treatment of sewage and multiple uses of water. It not only ensures the cleanliness of the purification solution, but also can continuously supply the self-cleaning structure without additional water replenishment. The water circuit structure is highly integrated and the circulation is reasonable. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-9 As shown, a waste gas treatment device for pesticide production includes a device base 1. A nozzle fixing seat 8 is fixedly installed at the upper port of the device base 1. Several evenly distributed waste gas nozzles are fixedly installed on the inner ring of the nozzle fixing seat 8. A waste gas inlet 5 is fixedly installed on the outer side of the nozzle fixing seat 8. The waste gas inlet 5 is fixedly installed on the device base 1 and extends to the outer side of the device base 1. The device body 2 is fixedly installed on the top of the device base 1. A copper foil fastener 10 is fixedly installed inside the bottom of the device body 2. A dust-collecting tapered copper foil cover 11 is fixedly installed at the bottom of the copper foil fastener 10. The nozzle fixedly installed on the nozzle mounting base 8 is aligned with the bottom of the dust-collecting tapered copper foil cover 11. Several evenly distributed dust adsorption strips 14 are fixedly installed on the side wall of the bottom of the dust-collecting tapered copper foil cover 11. A wave elastic element 12 is fixedly installed at the top of the tapered end of the dust-collecting tapered copper foil cover 11. A waste ash storage bin 7 is fixedly installed on the outer side of the bottom end of the exhaust gas inlet pipe 15, and the bottom end and outer side of the waste ash storage bin 7 form a certain air intake gap with the internal space of the device base 1, so that the gas enters through the bottom end of the waste ash storage bin 7.

[0024] Thus, pesticide production waste gas enters the device base 1 through waste gas inlet 5. Several waste gas nozzles installed inside the nozzle fixing seat 8 direct the waste gas flow towards the bottom of the dust-collecting conical copper foil cover 11. The upward waste gas first flows through the outer surface of the dust-collecting conical copper foil cover 11 and the dust adsorption strips 14 installed on the side wall of the cover. Through contact adsorption, large particles of dust in the waste gas are initially intercepted, achieving primary dust removal. The annular water curtain nozzle 16 set at the top of the device continuously sprays the purification liquid downwards. The liquid forms a continuous water curtain that comes into countercurrent contact with the upward waste gas, neutralizing and washing the harmful substances in the waste gas. Part of the liquid sprayed from the annular water curtain nozzle 16... The liquid is continuously guided and transported to the area above the wave-shaped elastic element 12 through the air inlet and water outlet holes 22 and the air inlet and water outlet square grooves 29. In the initial static state, the wave-shaped elastic element 12 completely blocks the water outlet position of the inclined drainage groove 13 on the copper foil fixing element 10, so that the drainage groove 13 is in a closed and water-blocking state, and the water cannot flow out. As the liquid is continuously injected into the area above the wave-shaped elastic element 12, the water volume and water pressure continue to accumulate. The water pressure continuously compresses the wave-shaped elastic element 12, causing the wave-shaped elastic element 12 to gradually deform downward. The space created by the deformation continuously accumulates water and plays a role in stabilizing pressure and storing energy. When the water pressure and water weight reach a threshold, the wave-shaped elastic element 12... The indentation deformation of component 2 is sufficient to break free from the obstruction and limitation of drainage channel 13. The originally closed drainage channel 13 becomes open, and the water accumulated above the corrugated elastic component 12 is quickly discharged along the inclined drainage channel 13. At the instant the water is discharged, the water pressure load above the corrugated elastic component 12 is instantly relieved. The corrugated elastic component 12 rebounds upward and resets itself instantly due to its own elastic structure, and then re-obstructs and seals the drainage channel 13 through its own corrugated structure. Since the annular water curtain nozzle 16 continuously supplies water, the corrugated elastic component 12 will continuously repeat the fully automatic cycle of sealing water accumulation → increasing water pressure and deforming downward → opening the channel for drainage and pressure relief → elastic rebound and resetting for sealing. 12 generates continuous, high-frequency, reciprocating micro-vibration. Because the bottom end of the ash-collecting tapered copper foil cover 11 is fixedly connected to the wave-elastic element 12, the high-frequency micro-vibration of the wave-elastic element 12 can synchronously drive the entire ash-collecting tapered copper foil cover 11 to vibrate at high frequency. The mechanical vibration force is used to completely shake off the sticky pesticide dust that is stubbornly attached and adhered to the bottom surface of the ash-collecting tapered copper foil cover 11 and the surface of the dust adsorption strip 14. The shaken-off dust particles fall freely under gravity and accurately fall into the waste ash storage bin 7 set on the outside of the bottom end of the exhaust gas inlet pipe 15 for centralized collection. This effectively prevents dust accumulation from clogging the pores of the ash-collecting tapered copper foil cover 11 and the exhaust gas airflow channel, ensuring the long-term smooth and stable operation of the equipment. Furthermore, such as Figures 2-4As shown; the copper foil fixing component 10 is provided with several drainage grooves 13, which are parallel to the inclined surface of the ash-collecting tapered copper foil cover 11, and one end of the drainage groove 13 is located at the bottom end of the connection between the wave-elastic component 12 and the ash-collecting tapered copper foil cover 11. Several sewage outlets 9 are provided at the bottom end of the device base 1, which are located above the copper foil fixing component 10; an exhaust gas inlet pipe 15 is fixedly installed at the center of the wave-elastic component 12, and several gas pipe side outlet grooves 30 are provided on the exhaust gas inlet pipe 15. An inner fixing member 28 is fixedly installed on the outside of the exhaust gas inlet pipe 15. Several air inlet and water outlet square grooves 29 are opened on the inner fixing member 28, and the air inlet and water outlet square grooves 29 are connected to the air outlet groove 30 on the side of the gas pipe. A sliding seat 31 is slidably installed on the outside of the inner fixing member 28. A fixing member 17 is provided on the outside of the sliding seat 31. The fixing member 17 is fixedly installed inside the device base 1. Several air inlet and water outlet holes 22 are opened on the sliding seat 31, and the air inlet and water outlet holes 22 are connected to the air inlet and water outlet square grooves 29.

[0025] Thus, pesticide production waste gas enters the equipment through the waste gas inlet pipe 15, and is discharged outward through the gas outlet groove 30 on the side wall of the waste gas inlet pipe 15. It then flows through the air inlet and water outlet groove 29 of the inner fixed component 28, and then diffuses upward through the air inlet and water outlet holes 22 on the sliding seat 31. Simultaneously, the equipment sprays and purifies the waste gas discharged from the air inlet and water outlet holes 22. Part of the pesticide liquid, which adsorbs residual pesticide in the waste gas, flows backward through the air inlet and water outlet holes 22 and the air inlet and water outlet groove 29, finally converging above the connection point between the wave-elastic component 12 and the ash-collecting tapered copper foil cover 11. The water body... The upper end of component 12 forms a pressure accumulation, which forces the wave-elastic component 12 to be compressed and deformed and temporarily store water. When the water reaches a certain flow rate, the water quickly flows into the multiple drainage channels 13 set on the parallel conical surface of the copper foil fixing component 10. The drainage channels 13 are arranged along the inclined surface of the ash-collecting conical copper foil cover 11, which can quickly and smoothly guide all the accumulated water to flow down and discharge, so that the wave-elastic component 12 can instantly depressurize and quickly rebound and deform. The sewage after flushing continues to collect along the drainage channels 13 and is finally discharged uniformly from the sewage outlet 9 at the bottom of the device base 1, realizing a continuous and automated working process of uniform air intake of exhaust gas, water pressure energy storage, elastic vibration ash cleaning, and directional sewage discharge.

[0026] Furthermore, such as Figures 5-6 As shown; a water storage tank 18 is fixedly installed on the fixing member 17, and the inner ring side of the water storage tank 18 is fixedly installed on the outer side of the sliding seat 31, with the bottom end of the water storage tank 18 located above the air inlet and water outlet holes 22; a number of guide posts 19 are fixedly installed on the sliding seat 31, and the guide posts 19 are evenly distributed on the sliding seat 31. A first return spring 21 is sleeved on the outer side of the guide post 19, and the two ends of the first return spring 21 are respectively connected to the water storage tank 18 and the sliding seat 31. An air bag 20 is fixedly installed at the top of the guide post 19, and the air bag 20 is located at the bottom of the inside of the water storage tank 18.

[0027] Thus, in the initial stage of equipment startup, the annular water curtain nozzle 16 has not yet formed a stable purified water curtain, and the exhaust gas cannot escape upward through the air inlet and water outlet 22, forcibly locking the exhaust gas from leakage. This avoids the exhaust gas being directly discharged and causing air pollution in the initial stage when the water curtain is not formed and has no purification capacity. After the water curtain is formed by the annular water curtain nozzle 16, the water flowing into the water storage tank 18 acts on the airbag 20 to generate upward buoyancy. At the same time, the exhaust gas continuously discharged from the lower end generates upward gas thrust through the air inlet and water outlet 22. The buoyancy of the airbag 20 and the gas thrust at the bottom together overcome the elasticity of the first reset spring 21, pushing the sliding seat 31 to move upward as a whole, so that the air inlet and water outlet 22 is kept above the water in the water storage tank 18, and the air inlet and water outlet 22 is reconnected with the upper water storage chamber and the lower air passage. At this time, the normal water and gas diversion working state of upward gas flow purification and downward water flow pressure storage is realized, and the normal adaptive water control and elastic vibration dust removal cycle operation is entered.

[0028] Furthermore, such as Figures 1-9 As shown; a mixed medicine inlet 4 is fixedly installed above the exhaust gas inlet pipe 15. A high-pressure sliding component 23 is slidably installed inside the mixed medicine inlet 4. A second return spring 25 is fixedly connected to the bottom end of the high-pressure sliding component 23. The other end of the second return spring 25 is fixedly connected to one end of the exhaust gas inlet pipe 15. A water outlet groove 24 is opened at the top of the high-pressure sliding component 23. An annular water curtain nozzle 16 is fixedly installed on the outside of the mixed medicine inlet 4. The annular water curtain nozzle 16 is located below the water outlet groove 24. A baffle plate 2 is fixedly installed on the upper end of the fixing component 17. 6. The baffle plate 26 is located outside the outlet of the annular water curtain nozzle 16. A water curtain outlet groove 27 is provided on the fixing member 17. The water curtain outlet groove 27 passes through the fixing member 17 and is located inside the baffle plate 26. A gas storage chamber 6 is provided inside the device base 1 above the fixing member 17. A mixed medicine inlet 4 is fixedly installed at the center of the device base 1 and extends to the outside of the device base 1. An air outlet 3 is provided at the upper end of the device base 1 and is located on one side of the mixed medicine inlet 4.

[0029] Thus, the pesticide purification solution enters the equipment through the mixed solution inlet 4, which is installed through the outside of the equipment. The mixed solution inlet 4 is connected to a booster water pump. The water pressure provided by the external water pump directly acts on the upper surface of the high-pressure sliding member 23 inside the equipment. Under the action of hydraulic thrust, the high-pressure sliding member 23 slides downward and compresses the second return spring 25 assembled at its bottom end. The greater the inlet water pressure, the greater the downward stroke of the high-pressure sliding member 23. The water passage area between the water outlet groove 24 opened at the top of the high-pressure sliding member 23 and the annular water curtain nozzle 16 below automatically increases, realizing the adaptive matching of inlet water pressure and outlet water flow. Among them, the second return spring 25 plays an elastic limiting and buffering role for the downward limit stroke of the high-pressure sliding member 23. When the inlet pressure of the external water pump reaches the set high-pressure threshold, the high-pressure sliding member 23 moves down to the maximum stroke position. At this time, the outlet tank 24 and the annular water curtain nozzle 16 always maintain maximum conduction and connection, and will not be blocked or closed as the water pressure continues to rise. This ensures that the liquid pressure and spray flow rate entering the annular water curtain nozzle 16 remain constant, forming a stable and uniform 360° fully covered sealed liquid water curtain. After the external water pump stops and the water pressure at the mixed liquid inlet 4 disappears, the second reset spring 25 pushes the high-pressure sliding member 23 upward by its own elastic rebound, causing the outlet tank 24 to be misaligned and closed, cutting off the liquid channel to the annular water curtain nozzle 16. The equipment automatically stops spraying, preventing downtime. The liquid medicine continues to flow away and be wasted; the water mist and wastewater generated by the spraying operation of the annular water curtain nozzle 16 are all gathered and blocked by the baffle plate 26 on the outside of the equipment, which effectively avoids water mist turbulence and upward air leakage, and prevents water mist overflow from affecting the stability of the equipment operation; the wastewater intercepted by the baffle plate 26 is uniformly drawn into the water curtain outlet 27 set on the inside to achieve centralized flow guidance. After the exhaust gas passes through the bottom dust adsorption and interception, the middle constant pressure liquid medicine water curtain deep purification, and water and gas washing and separation, it enters the gas storage chamber 6 at the top of the equipment to complete the airflow stabilization, uniform flow and water and gas separation operation, which can effectively balance the instantaneous airflow fluctuations during the operation of the equipment. Finally, the purified gas is stably discharged from the gas outlet 3 at the top of the device.

[0030] The principle of the pesticide production waste gas treatment device provided in this embodiment is as follows: When the pesticide production waste gas treatment device is working, the pesticide production waste gas enters the device base 1 through the waste gas inlet 5. Several waste gas nozzles installed inside the nozzle fixing seat 8 direct the waste gas flow towards the bottom end of the ash-collecting conical copper foil cover 11. The gas after initial filtration enters through the waste gas inlet pipe 15 at the bottom end of the waste ash storage bin 7. In the initial stage of equipment startup, the annular water curtain nozzle 16 has not yet formed a stable purification water curtain. The air inlet and water outlet holes 22 are completely blocked below the water body in the water storage tank 18, thereby preventing the waste gas from escaping upwards and effectively avoiding the leakage of waste gas and environmental pollution during the unpurified stage of startup. After the equipment is running stably, the upper pesticide spraying system is in operation. During normal operation, the air and water pressures in the cavity tend to balance, and the sliding seat 31 moves downward to reset under pressure. At this time, the water inside the water storage tank 18 generates an upward buoyancy force on the airbag 20, while the exhaust gas at the bottom generates an upward gas thrust through the air inlet and water outlet holes 22. The dual thrusts together overcome the elasticity of the first reset spring 21 and push the sliding seat 31 upward as a whole, so that the air inlet and water outlet holes 22 and the air inlet and water outlet square grooves 29 are reconnected, and the equipment enters the normal water and air separation working state. The external neutralizing liquid is introduced into the center of the equipment through the mixed liquid inlet 4. The liquid pressure pushes the high-pressure sliding component 23 to compress the second reset spring 25, and automatically adjusts the conduction area of ​​the water outlet groove 24 according to the liquid pressure. The liquid overflows evenly into the annular water curtain nozzle 16, forming a 360° full coverage. A sealed liquid water curtain is used to neutralize and purify organic pollutants, odors, and harmful gases by allowing upward-moving exhaust gas to pass through it. Wastewater generated by the spraying is collected by baffle plate 26 and flows into the water curtain outlet trough 27, where it is divided into two circulation paths. One path, high-polluting wastewater, flows directly downwards and is discharged from wastewater outlet 9 to prevent pollutant accumulation and maintain purification efficiency. The other path, clean return wastewater, enters the storage tank 18 for storage, continuously providing working water for the water-air linkage and pressure-accumulating dust removal structure below. During normal exhaust gas intake, the exhaust gas is first directionally sprayed through the exhaust gas nozzles of the nozzle mounting base 8, impacting the bottom of the dust-collecting conical copper foil cover 11. The dust-collecting conical copper foil cover 11 and the dust adsorption strips 14 evenly arranged on the sidewalls complete the initial interception and adsorption of large dust particles. After adsorption, the exhaust gas... The exhaust gas enters from the bottom of the exhaust pipe 15 and spreads outward and upward evenly through the exhaust pipe side outlet groove 30, the air inlet and water outlet square groove 29, and the air inlet and water outlet hole 22. At the same time, the water in the water storage tank 18 flows backward through the air inlet and water outlet hole 22 and the air inlet and water outlet square groove 29 to accumulate above the wave elastic element 12, causing the wave elastic element 12 to be compressed and deformed and store water and energy. When the accumulated water reaches a certain flow rate, the water flows out quickly and releases pressure instantly along the multiple drainage grooves 13 arranged parallel to the conical surface on the copper foil fixing part 10. The wave elastic element 12 rebounds instantly and drives the dust collection cone copper foil cover 11 to vibrate at high frequency, which completely shakes off the sticky pesticide dust that is adhered to the surface. The dust falls by gravity and is collected in the waste ash storage bin 7 for unified collection.All flushing wastewater and circulating return water are guided and collected through drainage trough 13, and finally discharged from wastewater outlet 9 at the bottom of the device base 1, forming a complete closed-loop water circuit. Clean gas, after undergoing bottom dust removal, middle water washing self-cleaning, and upper liquid neutralization and multi-layer purification, enters gas storage chamber 6 for pressure stabilization, uniform flow, and buffering of airflow pulse fluctuations. Finally, it is discharged stably, continuously, and in compliance with standards from gas outlet 3 at the top of the device, achieving fully automatic, continuous, efficient, and self-cleaning treatment of pesticide waste gas.
