Abstract
Description
Technical Field
[0001] This invention relates to the field of traditional Chinese medicine processing equipment, specifically to a waste gas evaporation and deodorization device and method for traditional Chinese medicine processing. Background Technology
[0002] The production process of traditional Chinese medicine includes slicing and processing herbs. During the production of traditional Chinese medicine, a large amount of waste gas and dust are generated. This waste gas and dust not only harm human health but also cause environmental pollution, requiring the use of waste gas treatment equipment. When the treatment equipment treats the exhaust gas, it usually needs to filter the dust in the exhaust gas through water filtration. After a period of use, a large amount of dust will accumulate in the filtration water, and excessive dust accumulation will make it difficult for the gas to be discharged from the water.
[0003] According to patent document CN213610269U, a waste gas evaporation and deodorization device for traditional Chinese medicine processing includes a base, an injection pipe, a first treatment box, a second treatment box, and a main body. The main body is located at the center of the top of the base, and an activated carbon adsorption mesh is installed on one side of the main body. Germicidal lamps are installed on the inner walls of both ends of the main body on the side with the activated carbon adsorption mesh. The first treatment box is located on one side of the top of the main body, and the second treatment box is located on the top of the main body on one side of the first treatment box. The bottom of the second treatment box is filled with... The device contains a degradation liquid, and an inlet is located on one side of the top of the second treatment tank. In use, the locking bolt is rotated to pass through the first and second clamping plates and screwed into the locking nut. This allows the retaining ring to be installed on both outer walls of the top of the air injection pipe to seal the connection end of the air injection pipe, thereby reducing the leakage of exhaust gas during the use of the deodorization device. However, while this solution solves the problem of exhaust gas leakage, it cannot clean the filter components while purifying the exhaust gas multiple times, which is inconvenient during use. Summary of the Invention
[0004] To address the shortcomings of existing technologies, the present invention aims to provide a waste gas evaporation and deodorization device and method for processing traditional Chinese medicine, thereby solving the problems mentioned in the background art. The present invention has a novel structure. In use, the waste gas is first purified and filtered by the liquid inside the fixed box. The purified and filtered gas is discharged through both sides of the filter conveyor belt for further filtration. High-pressure gas ejected through the jet holes at the bottom of the fixed roller actively passes through the bottom of the filter conveyor belt. When the high-pressure waste gas is sprayed towards the bottom of the filter conveyor belt, the high-pressure gas cleans the filter plate. At the same time, the gas re-enters the liquid in the fixed box for further adsorption and filtration.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste gas evaporation and deodorization device for processing traditional Chinese medicine, comprising a base, a purification box fixed on the base, a connecting seat fixed on the side of the purification box, a deodorization box fixedly installed on the connecting seat, an exhaust pipe fixed on the side of the deodorization box, a drive motor and an air inlet pipe fixedly installed on the side of the purification box respectively, a water inlet pipe fixedly installed between the air inlet pipe and the drive motor, and a filter assembly and a purification assembly fixedly installed inside the purification box. The filter assembly includes a protective plate, and a filter conveyor belt is rotatably installed between the protective plates.
[0006] Furthermore, the filter conveyor belt includes filter bags, with filter sponge layers adhered and fixed between the filter bags, and an active roller is mounted on the drive motor, the active roller being rotatably mounted between the protective plates.
[0007] Furthermore, a fixing box is installed at the bottom of the active roller. The two ends of the fixing box are fixed to the inner wall of the protective plate by reinforcing rods. One end of the fixing box is fixed to the water inlet pipe, and the side of the fixing box has a groove.
[0008] Furthermore, one end of the air inlet cylinder is fixed to the fixed box, the bottom of the air inlet cylinder is fixed with an air inlet pipe, the other end of the filter conveyor belt is fixedly installed with a fixed roller, and one end of the air inlet pipe is fixed to the fixed roller.
[0009] Furthermore, the fixed roller has an annular groove, the bottom of the annular groove has an air jet hole, the bottom of the filter conveyor belt is equipped with a water tank, the side of the water tank has a slot, one end of the water tank is fixed with a drain pipe, and the drain pipe is fixedly installed on the purification box.
[0010] Furthermore, a dispersion component is fixed inside the water tank. The dispersion component includes a fixing pipe with a through hole on its side and a fixing rod welded to the top of the fixing pipe. The fixing rod is fixed to the inner wall of the water tank.
[0011] Furthermore, the purification assembly includes a support box, a movable plate is movably installed on the top of the support box, a circulation pipe is fixedly installed on the side of the support box, a sealing seat is fixed inside the support box, a fixing hole is opened on the sealing seat, a fixing cylinder is fixed on the side of the support box, and a fixing seat is fixedly installed on the side of the purification box.
[0012] Furthermore, a jet pipe is fixed on the sealing seat, an extraction pipe is fixed at the bottom of the jet pipe, a water pump is fixedly installed on the extraction pipe, a positioning pipe is fixedly installed inside the fixing hole, and an opening is made on the positioning pipe.
[0013] Furthermore, a diversion pipe is fixed to the side of the positioning tube, an integrated pipe is fixed to one end of the diversion pipe, and a fan is fixedly installed on one side of the integrated pipe.
[0014] A method for evaporating and deodorizing waste gas used in the processing of traditional Chinese medicine specifically includes the following steps:
[0015] Step 1: Waste gas collection. Install a gas collection hood or sealed cover above the evaporation point of the Chinese medicine extraction tank, concentration pot, dryer or decoction machine to collect the waste gas containing medicinal smell, water vapor and VOCs.
[0016] Step 2: Pretreatment, dust removal of exhaust gas, including cyclone dust removal: removing large particles of powder and dust; bag or cartridge dust removal: fine filtration, dust emission ≤10mg / m³; wet dust removal: spray dust removal for wet and sticky dust.
[0017] Step 3: Main deodorization. After pretreatment, the waste gas enters the activated carbon adsorption tower to adsorb odor molecules such as volatile oils, terpenes, and aldehydes from traditional Chinese medicine. After adsorption saturation, the gas is desorbed and regenerated or the carbon material is replaced.
[0018] Step 4: Deep purification, through photocatalytic oxidation to decompose recalcitrant odors and trace amounts of VOCs, and secondary activated carbon adsorption to ensure no odor emissions;
[0019] Step 5: Mark emissions. The qualified exhaust gas is discharged through the chimney, and the height and location meet the environmental impact assessment requirements.
[0020] The beneficial effects of this invention are:
[0021] 1. In use, the waste gas is first purified and filtered by the liquid inside the fixed box. The purified and filtered gas is discharged through both sides of the filter conveyor belt for further filtration. The high-pressure gas ejected through the jet hole at the bottom of the fixed roller actively passes through the bottom of the filter conveyor belt. When the high-pressure waste gas is sprayed to the bottom of the filter conveyor belt, the high-pressure gas cleans the filter plate. At the same time, the gas re-enters the liquid in the fixed box for further adsorption and filtration.
[0022] 2. In this invention, the filter conveyor belt passes through the air jet holes in sequence under the drive of the active roller. The filter conveyor belt filters the exhaust gas through the moving cover plate. It also enables cleaning of the filter conveyor belt while it is moving without stopping the machine. When the filter conveyor belt moves on the top of the water tank, the arc groove on the top of the water tank can clean the outer wall of the filter conveyor belt by scraping.
[0023] 3. In this invention, after the gas is filtered by the filter assembly, it enters the positioning tube. The water pump drives the liquid at the bottom of the support box to move upward. The liquid flows into the fixing hole through the sealing seat and flows downward from the fixing hole to form a circular waterfall. The gas sprayed out of the positioning tube is filtered again through the waterfall, thus completing multiple filtrations. After the exhaust gas passes through the activated carbon adsorption plate inside the deodorization box, it meets the deodorization emission standards and is discharged. Attached Figure Description

Detailed Implementation
[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0037] Please see Figures 1 to 11 This invention provides a technical solution: a waste gas evaporation and deodorization device for traditional Chinese medicine processing, comprising a base 1, a purification box 2 fixed on the base 1, a connecting seat 7 fixed on the side of the purification box 2, a deodorization box 8 fixedly installed on the connecting seat 7, an exhaust pipe 9 fixedly installed on the side of the deodorization box 8, a drive motor 5 and an air inlet pipe 3 fixedly installed on the side of the purification box 2 respectively, a water inlet pipe 4 fixedly installed between the air inlet pipe 3 and the drive motor 5, a filter assembly 10 and a purification assembly 11 fixedly installed inside the purification box 2, the filter assembly 10 including a protective plate 12, and a filter conveyor belt 13 rotatably installed between the protective plates 12, so that... During use, the exhaust gas is injected into the interior of the fixed box 19 through the air inlet 3. The gas tumbles in the liquid inside the fixed box 19 under normal pressure. At the same time, the liquid adsorbs the solids in the exhaust gas. After the gas passes through the liquid for the first time, it moves upward. The gas accumulates and diffuses outward from the interior of the filter conveyor belt 13. When the air inlet 3 is inletting, a portion of the exhaust gas will enter the fixed roller 20 through the air inlet pipe 17. The exhaust gas discharged from the interior of the fixed roller 20 actively passes through the bottom of the filter conveyor belt 13. When the exhaust gas moves downward actively, it will drive the exhaust gas between the filter conveyor belts 13 to move downward through the groove 40. Driven by the airflow from the jet hole, it moves downward and accelerates the filtration.
[0038] In this embodiment, the filter conveyor belt 13 includes filter bags, with filter sponge layers adhered and fixed between the filter bags. An active roller 18 is mounted on the drive motor 5, and the active roller 18 is rotatably mounted between the protective plates 12. A fixing box 19 is installed at the bottom of the active roller 18. Both ends of the fixing box 19 are fixed to the inner wall of the protective plate 12 by reinforcing rods. One end of the fixing box 19 is fixed to the water inlet pipe 4, and a groove 40 is formed on the side of the fixing box 19. One end of the air inlet cylinder 3 is fixed to the fixed box 19, and an air inlet pipe 17 is fixed to the bottom of the air inlet cylinder 3. A fixed roller 20 is fixedly installed at the other end of the filter conveyor belt 13, and one end of the air inlet pipe 17 is fixed to the fixed roller 20. The filter conveyor belt 13 uses filter bags on both sides to clamp and fix the filter sponge layer at the center. The filter bags also provide protection for the rotation of the filter sponge layer, preventing damage from pulling forces. When cleaning the filter conveyor belt 13 later, the channel from the air inlet cylinder 3 into the fixed box 19 is closed, and high pressure is applied to the exhaust gas. The gas then enters the air inlet pipe 17 and the fixed roller 20. The high-pressure exhaust gas is sprayed downward through the jet hole. At the same time, the drive motor 5 is started to drive the active roller 18 to rotate. The active roller 18 drives the bottom of the filter conveyor belt 13 to change position. Under the blowing of the high-pressure gas, the dust adhering to the filter sponge plate and filter bag is squeezed out and collected for cleaning. The gas carries solid impurities into the fixed pipe 23. The gas inside the fixed pipe 23 is dispersed through the through hole 24. The dispersion reduces the impact force. Through the multi-point nature of the through hole 24, the gas carries the solid impurities into the liquid inside the water tank 14 for re-adsorption and filtration.
[0039] In this embodiment, the fixed roller 20 has an annular groove 21, and the bottom of the annular groove 21 has an air jet hole. A water tank 14 is installed at the bottom of the filter conveyor belt 13. The side of the water tank 14 has a slot 15. A drain pipe 16 is fixed to one end of the water tank 14 and is fixedly installed on the purification box 2. A dispersion component 22 is fixed inside the water tank 14. The dispersion component 22 includes a fixed pipe 23. The side of the fixed pipe 23 has a through hole 24. A fixing rod 25 is welded to the top of the fixed pipe 23 and is fixed to the inner wall of the water tank 14. The purification component 11 includes a support box 26, a movable plate 28 is movably installed on the top of the support box 26, a circulation pipe 29 is fixedly installed on the side of the support box 26, a sealing seat 30 is fixed inside the support box 26, a fixing hole 31 is opened on the sealing seat 30, a fixing cylinder 27 is fixed on the side of the support box 26, and a fixing seat 6 is fixedly installed on the side of the purification box 2. The gas after passing through the water tank 14 is discharged outward through the slot 15. The fan 39 generates suction to guide the waste gas into the integrated pipe 36 and guide it into the positioning pipe 32. It is discharged outward through the opening 38 on the side of the positioning pipe 32. At the same time as the gas is discharged in the positioning pipe 32, the liquid at the bottom of the support box 26 is moved upward. After the liquid moves upward, it flows downward through the top of the fixing hole 31.
[0040] In this embodiment, a jet pipe 33 is fixed on the sealing seat 30, and an extraction pipe 34 is fixed to the bottom of the jet pipe 33. A water pump 35 is fixedly installed on the extraction pipe 34. A positioning pipe 32 is fixedly installed inside the fixing hole 31, and an opening 38 is formed on the positioning pipe 32. A diversion pipe 37 is fixed to the side of the positioning pipe 32, and an integrated pipe 36 is fixed to one end of the diversion pipe 37. A fan 39 is fixedly installed on one side of the integrated pipe 36. When the liquid flows downward from the fixing hole 31, the positioning pipe 32 provides hollow support for the center of the liquid. The liquid flows downward from the annular waterfall. The gas ejected from the positioning pipe 32 is adsorbed and filtered again by the liquid. The adsorbed and filtered gas is discharged outward through the fixing cylinder 27. The gas is adsorbed and purified by the activated carbon adsorption plate inside the deodorization box 8, and finally meets the emission standards before being discharged.
[0041] A method for evaporating and deodorizing waste gas used in the processing of traditional Chinese medicine specifically includes the following steps:
[0042] Step 1: Waste gas collection. Install a gas collection hood or sealed cover above the evaporation point of the Chinese medicine extraction tank, concentration pot, dryer or decoction machine to collect the waste gas containing medicinal smell, water vapor and VOCs.
[0043] Step 2: Pretreatment, dust removal of exhaust gas, including cyclone dust removal: removing large particles of powder and dust; bag or cartridge dust removal: fine filtration, dust emission ≤10mg / m³; wet dust removal: spray dust removal for wet and sticky dust.
[0044] Step 3: Main deodorization. After pretreatment, the waste gas enters the activated carbon adsorption tower to adsorb odor molecules such as volatile oils, terpenes, and aldehydes from traditional Chinese medicine. After adsorption saturation, the gas is desorbed and regenerated or the carbon material is replaced.
[0045] Step 4: Deep purification, through photocatalytic oxidation to decompose recalcitrant odors and trace amounts of VOCs, and secondary activated carbon adsorption to ensure no odor emissions;
[0046] Step 5: Mark emissions. The qualified exhaust gas is discharged through the chimney, and the height and location meet the environmental impact assessment requirements.
[0047] Working Principle: During operation, exhaust gas is injected into the fixed box 19 through the air inlet 3. Under normal pressure, the gas tumbles in the liquid inside the fixed box 19. Simultaneously, the liquid adsorbs solids in the exhaust gas, causing it to initially filter and rise. As the gas accumulates, it diffuses outward from the inside of the filter conveyor belt 13. When air is introduced through the air inlet 3, a portion of the exhaust gas enters the fixed roller 20 through the air inlet pipe 17. The exhaust gas discharged from inside the fixed roller 20 actively passes through the bottom of the filter conveyor belt 13. As the exhaust gas moves downward, it drives the filter conveyor belt. The exhaust gas between 13 moves downward through the groove 40, and is accelerated to filter by the airflow from the jet nozzles. When cleaning the filter conveyor belt 13 is required later, the channel from the air inlet cylinder 3 into the fixed box 19 is closed, and the exhaust gas is pressurized and enters the air inlet pipe 17 and the fixed roller 20. The high-pressure exhaust gas is ejected downward through the jet nozzles, and at the same time, the drive motor 5 is started to drive the active roller 18 to rotate. The active roller 18 drives the bottom of the filter conveyor belt 13 to change position. Under the blowing of the high-pressure gas, the dust adhering to the filter sponge plate and filter bag is squeezed out and collected for cleaning. The gas carries solid impurities into the fixed pipe 23. The gas inside the fixed pipe 23 is dispersed through the through hole 24, which reduces the impact force. Through the multi-point nature of the through hole 24, the gas carries the solid impurities into the liquid inside the water tank 14 for further adsorption and filtration. The gas after passing through the water tank 14 is discharged outward through the slot 15. The fan 39 generates suction to guide the waste gas into the integrated pipe 36 and then into the positioning pipe 32. The gas is discharged outward through the opening 38 on the side of the positioning pipe 32. At the same time as the gas is discharged from the positioning pipe 32, the liquid at the bottom of the support box 26 is moved upward, and the water pump 35 generates suction. The liquid at the bottom of the support box 26 is moved upward. After the movement, the liquid slowly falls onto the top of the sealing seat 30 through the jet pipe 33 at the top of the extraction pipe 34. After the liquid moves upward, it flows downward through the top of the fixing hole 31. When the liquid flows downward from the fixing hole 31, the positioning pipe 32 provides hollow support for the center of the liquid. The liquid flows downward from the annular waterfall. The gas sprayed out by the positioning pipe 32 is adsorbed and filtered again by the liquid. The adsorbed and filtered gas is discharged outward through the fixing cylinder 27. The gas is adsorbed and purified by the activated carbon adsorption plate inside the deodorizing box 8 and finally meets the emission standards before being discharged.
