Description

Technical Field

[0001] This invention relates to the field of VOC treatment technology, specifically to a water treatment device for VOC treatment. Background Technology

[0002] VOCs are volatile organic compounds. According to the World Health Organization, VOCs are various organic compounds with boiling points ranging from 50°C to 260°C at room temperature. The main components of VOCs include hydrocarbons, halogenated hydrocarbons, oxygenated hydrocarbons, and nitrogenous hydrocarbons, including benzene compounds, organochlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, acids, and petroleum hydrocarbons. VOCs are very harmful. When VOCs reach a certain concentration in indoor air, people may begin to experience headaches, nausea, and weakness in the limbs. Prolonged exposure can damage the liver, kidneys, brain, and nervous system, and may even cause convulsions, coma, and memory loss, leading to serious consequences. VOCs also harm the environment. To reduce the concentration of VOCs in the environment, gas recovery devices are needed to collect and remove VOCs from the environment.

[0003] Chinese patent CN207786256U discloses a water treatment device for VOC treatment, comprising a water film tank, a return water tank, a movable water tank, and a water filter tank. One end of the water film tank is connected to the return water tank via a pipe. The inlet of the water film tank is connected to the outlet of the movable water tank via a water supply pipe. The movable water tank is connected to the water filter tank via a pipe. An air inlet is provided on the top of the water film tank. Atomizing nozzles are installed inside the water film tank. A water film layer is installed inside the water film tank. A water-proof layer is installed inside the return water tank. This patent can achieve water film filtration and purification treatment of all VOC pollutants in the air, ensuring that air emissions meet standards. It is simple to operate, effectively improves air quality, and centrally recovers and filters the water mist that adsorbs VOC pollutants, thus thoroughly treating VOC pollutants. Furthermore, the water used for adsorbing VOC pollutants can be recycled, effectively reducing water consumption and costs for VOC treatment, and is energy-saving and environmentally friendly.

[0004] However, current water treatment devices have the following problems: the water treatment device only adsorbs VOC pollutants in the air onto water mist through a water film box. For VOCs, a gaseous pollutant, the effect of water mist adsorption of VOC pollutants is very limited. VOCs are gaseous substances, and water mist has difficulty effectively capturing them, especially for VOC components with small molecular size. Therefore, we propose a water treatment device for VOC treatment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a water treatment device for VOC control, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water treatment device for VOC treatment, comprising a base plate, wherein a washing tank, an activated carbon box, and an exhaust assembly are fixed sequentially from left to right on the top of the base plate; an air inlet pipe is fixed to the bottom of the washing tank, the air inlet pipe is L-shaped, and the vertical branch of the air inlet pipe protrudes 50 centimeters beyond the bottom of the inner wall of the washing tank; a baffle is fixed to the top of the vertical branch of the air inlet pipe to form a shield at the top of the vertical branch of the air inlet pipe; and the bottom of the washing tank is eccentric. A drain pipe is fixed at the location. The exhaust assembly is connected to the activated carbon box via a pipe. The activated carbon box is connected to the top of the washing tank via an exhaust pipe. A filter screen is fixed to the lower inner wall of the washing tank. A spray assembly is installed above the filter screen. The spray assembly includes a pump, which is fixed to the outer wall of the washing tank. The pump's inlet is connected to an external water source. An L-shaped pipe is fixed to the pump's outlet. The horizontal branch of the L-shaped pipe is located inside the washing tank. The bottom of the horizontal branch of the L-shaped pipe is evenly spaced. Several spray pipes are equidistantly and rotatably installed. Torsion springs are provided between the spray pipes and the outer walls of the horizontal branch pipes of the L-shaped pipe. A treatment device is located above the spray assembly. The treatment device includes two side plates fixed to both sides of the inner wall of the washing tank, a receiving box that penetrates and slides on the front of the washing tank, and sliding rods that penetrate and slide on both sides of the top of the washing tank. The two side plates are respectively located on both sides of the receiving box. The receiving box contains VOC treatment agent. A circular pipe for air intake is fixed in the middle of the receiving box. A spring is provided between the sliding rods and the top of the washing tank. A disc is fixed between the bottom of the two sliding rods. A 15-centimeter gap is left between the disc and the top of the receiving box. An annular baffle is fixed at the bottom of the disc, extending below the liquid surface of the VOC treatment agent in the receiving box. During the process of VOC gas entering the activated carbon box through the exhaust pipe, the VOC gas passes through the circular pipe of the receiving box. Under the obstruction of the disc and the annular baffle, the VOC gas enters the VOC treatment agent in the receiving box.

[0007] According to the above technical solution, the treatment device further includes a rotating rod rotatably installed on the top of the inner wall of the washing tank. The rotating rod is driven by a motor, and a slip ring is slidably installed on the outside of the rotating rod. The slip ring passes through and is rotatably installed on the top of the disc. Four L-shaped mesh plates are evenly fixed on the circumference of the lower outer wall of the slip ring. The L-shaped mesh plates are located inside the receiving box. At the same time, the operator drives the rotating rod to rotate through the motor, and the rotating rod drives the L-shaped mesh plates to rotate through the slip ring. The L-shaped mesh plates agitate the VOC gas injected into the VOC treatment agent, thereby causing the mesh of the L-shaped mesh plates to disperse the large bubble-like VOC gas in the VOC treatment agent into small bubble-like VOC gas.

[0008] According to the above technical solution, a wetting device is provided above the filter screen. The wetting device includes a star-shaped groove ring and an L-shaped column. The star-shaped groove ring is fixed to the upper outer wall of the rotating rod. A star-shaped groove is formed at the top of the star-shaped groove ring. The L-shaped column is slidably installed on the top of the inner wall of the washing tank. One end of the L-shaped column is slidably installed inside the star-shaped groove of the star-shaped groove ring. The other end of the L-shaped column is hinged to a hinge rod. A vertical rod is hinged to the end of the hinge rod away from the L-shaped column. The vertical rod passes through and is slidably installed on the top of a side plate on one side. A spring is provided between the vertical rod and the top of the side plate. A semi-circular rod is fixed to the bottom of the rod. Several pressure plates are evenly and equidistantly fixed to the inner wall of the semi-circular rod. Several through holes are evenly and equidistantly opened on the top of the pressure plates. A sponge block is fixed to the bottom of the pressure plate. Each time the L-shaped column moves towards the inner wall of the washing tank, the L-shaped column pushes the hinge rod to drive the vertical rod to move downward along the inner wall of the washing tank. The spring corresponding to the vertical rod is compressed. During the downward movement of the vertical rod, it will drive the pressure plate to move downward through the semi-circular rod. The pressure plate will drive the sponge block to move downward until the sponge block contacts the top of the filter screen. As the pressure plate continues to move, the pressure plate will squeeze the sponge block.

[0009] According to the above technical solution, a number of friction rods are evenly and equidistantly fixed on the outer wall of the pressure plate in the middle, and a friction ring is fixed on the outer wall of each of the spray pipes. The outer walls of the friction rods and friction rings are both rough surfaces. The outer walls of the friction rods are in contact with the outer walls of the friction rings. During the rotation of the rotating rod, the rotating rod drives the star-shaped groove ring to rotate. The star-shaped groove of the star-shaped groove ring pushes the L-shaped column rod to move back and forth along the top of the inner wall of the washing tank. At the same time, each time the semi-circular rod drives the pressure plate to move downward, the pressure plate drives the friction rod to move accordingly. Under the action of the friction force between the friction rod and the friction ring, the friction rod drives the friction ring to rotate, and the friction ring drives the spray pipe to rotate at the horizontal branch of the L-shaped pipe.

[0010] According to the above technical solution, an injection device is provided at the disc. The injection device includes a flower groove ring and two U-shaped plates. The flower groove ring is fixed to the top of a sliding ring by a bracket. A flower groove is fixed to the bottom of the flower groove ring. The two U-shaped plates are respectively fixed to the top two sides of the disc. A folding pouch is fixed to the side of the two U-shaped plates that are close to each other. A sliding plate is fixed to the side of the two folding pouches that are close to each other, and the sliding plate is slidably mounted on the top of the disc. A round block is fixed to the top of the sliding plate. The round block is slidably mounted inside the flower groove of the flower groove ring. The two sliding plates are close to each other. One-way air inlets are fixed on one side, and one-way jet pipes are fixed at the bottom of the U-shaped plate. The one-way jet pipes penetrate the top of the disc. The one-way air inlets are used to control the one-way air intake of the folding bladder, and the one-way jet pipes are used to control the one-way air exhaust of the folding bladder. During the rotation of the rotating rod and the slip ring, the slip ring drives the flower groove ring to rotate. The flower groove of the flower groove ring will drive the round block to push the slide plate to move along the top of the disc towards the U-shaped plate. The slide plate squeezes the folding bladder, and the VOC gas absorbed in the folding bladder and purified by the VOC treatment agent is sprayed into the VOC treatment agent in the container box through the one-way jet pipe.

[0011] This invention provides a water treatment device for VOC control. It has the following beneficial effects:

[0012] (1) The present invention, through the setting of the processing device, enables the disc and the annular baffle to drive the VOC gas into the VOC treatment agent in the container box. The VOC treatment agent effectively removes the harmful components in the VOC gas through adsorption, chemical reaction and other methods. The design of the disc and the annular baffle can change the flow direction of the VOC gas during the flow process, so as to increase the contact time between the VOC gas and the surface of the VOC treatment agent. The longer contact time helps the harmful substances in the VOC gas to react with or be adsorbed by the VOC treatment agent, thereby improving the treatment effect. At the same time, the rotating rod and the slip ring work together to drive the L-shaped mesh plate to stir the VOC gas injected into the VOC treatment agent. This causes the mesh of the L-shaped mesh plate to disperse the large bubble-shaped VOC gas in the VOC treatment agent into small bubble-shaped VOC gas. After the large bubble VOC gas is converted into small bubble VOC gas, the surface area of ​​the VOC gas increases significantly. The small bubble VOC gas has a larger surface area to contact the VOC treatment agent than the large bubble VOC gas, which can accelerate the reaction or adsorption of harmful substances in the VOC gas with the VOC treatment agent, thereby improving the purification efficiency.

[0013] (2) The present invention, through the setting of the humidification device, enables the rotating rod, star-shaped groove ring, L-shaped column rod, hinge rod, vertical rod, washing tank, and semi-circular rod to work together to drive the pressure plate to squeeze the sponge block. The water adsorbed by the sponge block will be squeezed onto the filter screen, and the water will form a thin film on the filter screen. This thin film can help the filter screen capture and adhere to the solid particulate impurities contained in the VOC gas. The water acts as an "adsorbent" and can enhance the filter screen's ability to adhere to solid particles in the VOC gas, thereby improving the filter screen's filtration efficiency. At the same time, as the water squeezed out by the sponge block enters the filter screen, the solid particulate impurities on the surface of the filter screen will also be partially washed or rinsed by the water. Especially when the filter screen has been used for a long time, this cleaning effect helps to maintain the filter screen's regeneration ability, thereby reducing the impact of long-term accumulation of impurities. At the same time, the semi-circular rod, pressure plate, friction rod, and friction ring work together to drive the spray pipe to rotate at the horizontal branch of the L-shaped pipe. The rotation of the spray pipe allows the liquid to be evenly distributed in the internal space of the washing tank.

[0014] (3) The present invention, through the setting of the injection device, enables the rotating rod, slip ring, flower groove ring, round block, slide plate, disc and U-shaped plate to work together to drive the slide plate to squeeze the folded bag. The VOC gas absorbed in the folded bag and purified by the VOC treatment agent is injected into the VOC treatment agent in the container box through the one-way jet pipe, and the purified VOC gas is reintroduced into the VOC treatment agent, which helps the VOC treatment agent to continue to play a purification role. This can improve the efficiency of the VOC treatment agent, especially when treating VOC gas components that are difficult to remove. Through continuous treatment, the VOC treatment agent can more effectively decompose or adsorb the remaining pollutants. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figures 1-11One embodiment of the present invention is as follows: a water treatment device for VOC treatment includes a base plate 1. A washing tank 4, an activated carbon box 3, and an exhaust assembly 2 are sequentially fixed to the top of the base plate 1 from left to right. An air inlet pipe 42 is fixed to the bottom of the washing tank 4. The air inlet pipe 42 is L-shaped, and its vertical branch protrudes 50 centimeters beyond the bottom of the inner wall of the washing tank 4. A baffle is fixed to the top of the vertical branch of the air inlet pipe 42 to form a shield. A drain pipe 43 is fixed eccentrically at the bottom of the washing tank 4. The exhaust assembly 2 and the activated carbon box 3 are connected by a pipe. The activated carbon box 3 and the washing tank 4 are connected by a pipe. The tops of the washing tanks 4 are connected by an exhaust pipe 41. A filter screen 6 is fixed to the lower inner wall of the washing tank 4. A spray assembly 5 is installed above the filter screen 6. The spray assembly 5 includes a pump 51, which is fixed to the outer wall of the washing tank 4. The inlet of the pump 51 is connected to an external water source. An L-shaped pipe 52 is fixed to the outlet of the pump 51. The horizontal branch of the L-shaped pipe 52 is located inside the washing tank 4. Several spray pipes 53 are evenly and equidistantly installed at the bottom of the horizontal branch of the L-shaped pipe 52. A torsion spring is provided between the spray pipes 53 and the outer wall of the horizontal branch of the L-shaped pipe 52. A treatment device 7 is installed above the spray assembly 5. 7 includes two side plates 72 fixed to both sides of the inner wall of the washing tank 4, a receiving box 71 that penetrates and slides on the front of the washing tank 4, and sliding rods 73 that penetrate and slide on both sides of the top of the washing tank 4. The two side plates 72 are respectively set on both sides of the receiving box 71. The receiving box 71 contains VOC treatment agent. A round pipe for air intake is fixed in the middle of the receiving box 71. A spring is provided between the sliding rods 73 and the top of the washing tank 4. A disc 74 is fixed between the bottom of the two sliding rods 73. A 15 cm gap is left between the disc 74 and the top of the receiving box 71. An annular baffle 75 is fixed at the bottom of the disc 74. The baffle 75 extends below the liquid surface of the VOC treatment agent in the container 71. Through the above structure, VOC gas is introduced into the VOC treatment agent in the container 71. The VOC treatment agent effectively removes harmful components from the VOC gas through adsorption, chemical reaction and other methods. Furthermore, the design of the disc 74 and the annular baffle 75 can change the flow direction of the VOC gas during its flow, increasing the contact time between the VOC gas and the surface of the VOC treatment agent. The longer contact time helps the harmful substances in the VOC gas to react with or be adsorbed by the VOC treatment agent, thereby improving the treatment effect.

[0029] The treatment device 7 also includes a rotating rod 76 rotatably mounted on the top of the inner wall of the washing tank 4. The rotating rod 76 is driven by a motor. A slip ring 77 is slidably mounted on the outside of the rotating rod 76. The slip ring 77 passes through and is rotatably mounted on the top of the disc 74. Four L-shaped mesh plates 78 are evenly fixed around the lower outer wall of the slip ring 77. The L-shaped mesh plates 78 are located inside the receiving box 71. Through the above structure, the mesh of the L-shaped mesh plates 78 disperses the large bubble-shaped VOC gas in the VOC treatment agent into small bubble-shaped VOC gas. After the large bubble VOC gas is converted into small bubble VOC gas, the surface area of ​​the VOC gas increases significantly. The small bubble VOC gas has a larger surface area than the large bubble VOC gas and can contact the VOC treatment agent, which can accelerate the reaction or adsorption of harmful substances in the VOC gas with the VOC treatment agent, thereby improving the purification efficiency.

[0030] A wetting device 8 is provided above the filter screen 6. The wetting device 8 includes a star-shaped groove ring 81 and an L-shaped column rod 82. The star-shaped groove ring 81 is fixed to the upper outer wall of the rotating rod 76. A star-shaped groove is opened at the top of the star-shaped groove ring 81. The L-shaped column rod 82 is slidably installed on the top of the inner wall of the washing tank 4. One end of the L-shaped column rod 82 is slidably installed inside the star-shaped groove of the star-shaped groove ring 81. The other end of the L-shaped column rod 82 is hinged to a hinge rod 83. A vertical rod 84 is hinged to the end of the hinge rod 83 away from the L-shaped column rod 82. The vertical rod 84 passes through and is slidably installed on the top of the side plate 72 on one side. A spring is provided between the vertical rod 84 and the top of the side plate 72. A semi-circular rod 85 is fixed to the bottom of the vertical rod 84. Several pressure plates 86 are evenly and equidistantly fixed on the inner wall of the semi-circular rod 85. The top of the pressure plates 86 is evenly and equidistantly opened. Several through holes are provided, and a sponge block 87 is fixed to the bottom of the pressure plate 86. Through the above structure, the pressure plate 86 will squeeze the sponge block 87, and the water absorbed by the sponge block 87 will be squeezed onto the filter screen 6. The water forms a thin film on the filter screen 6. This thin film can help the filter screen 6 capture and adhere to solid particulate impurities contained in VOC gas. The water acts as an "adsorbent", which can enhance the filter screen 6's ability to adhere to solid particles in VOC gas, thereby improving the filtration efficiency of the filter screen 6. At the same time, as the water squeezed out by the sponge block 87 enters the filter screen 6, some of the solid particulate impurities on the surface of the filter screen 6 will also be washed or rinsed by the water. Especially when the filter screen 6 is used for a long time, this cleaning effect helps to maintain the regeneration ability of the filter screen 6, thereby reducing the impact of long-term accumulation of impurities.

[0031] Several friction rods 88 are evenly and equidistantly fixed on the outer wall of the central pressure plate 86, and several friction rings 89 are fixed on the outer wall of the spray pipes 53. The outer walls of the friction rods 88 and the friction rings 89 are rough surfaces. The outer walls of the friction rods 88 and the friction rings 89 are in contact. During the rotation of the rotating rod 76, the rotating rod 76 drives the star-shaped groove ring 81 to rotate. The star-shaped groove of the star-shaped groove ring 81 pushes the L-shaped column rod 82 to move back and forth along the top of the inner wall of the washing tank 4. Through the above structure, the friction rods 88 drive the friction rings 89 to rotate. The friction rings 89 drive the spray pipes 53 to rotate at the horizontal branch of the L-shaped pipe 52. The rotation of the spray pipes 53 allows the liquid to be evenly distributed in the internal space of the washing tank 4.

[0032] In use, VOC gas is transferred to the washing tank 4 through the inlet pipe 42. The pump 51 is started, and the pump 51 draws water from the external source and transmits it to the spray pipe 53 through the L-shaped pipe 52. With the cooperation of the filter screen 6, the water mist sprayed by the spray assembly 5 and the mesh of the filter screen 6 filter the odor, dust, and fixed particles of the VOC gas. Then, the VOC gas in the washing tank 4 is introduced into the activated carbon box 3 through the exhaust pipe 41. The activated carbon in the activated carbon box 3 further filters the VOC gas. The filtered gas is discharged through the exhaust assembly 2 in compliance with standards. During the process of the VOC gas entering the activated carbon box 3 through the exhaust pipe 41, the VOC gas passes through the circular tube of the receiving box 71. Under the obstruction of the disc 74 and the annular baffle 75, the VOC gas enters the VOC treatment agent in the receiving box 71. The VOC treatment agent effectively removes harmful components from the VOC gas through adsorption, chemical reaction, and other methods. The disc 74 and the annular baffle 75 further enhance the VOC gas's effectiveness. The design of component 5 alters the flow direction of VOC gas during its flow, increasing the contact time between the VOC gas and the surface of the VOC treatment agent. This longer contact time facilitates the reaction or adsorption of harmful substances in the VOC gas with the VOC treatment agent, thereby improving the treatment effect. Simultaneously, the operator drives the rotating rod 76 via a motor, which in turn drives the L-shaped mesh plate 78 to rotate through the slip ring 77. The L-shaped mesh plate 78 agitates the VOC gas injected into the VOC treatment agent, causing the mesh openings of the L-shaped mesh plate 78 to disperse large bubbles of VOC gas into smaller bubbles. After the large bubbles of VOC gas are converted into small bubbles, the surface area of ​​the VOC gas increases significantly. The smaller bubbles have a larger surface area to contact the VOC treatment agent, accelerating the reaction or adsorption of harmful substances in the VOC gas with the VOC treatment agent, thus improving the purification efficiency.

[0033] It should be noted that when the VOC treatment agent in the container 71 needs to be replaced, the slide bar 73 is pulled upward, the spring corresponding to the slide bar 73 is stretched, and the slide bar 73 drives the annular baffle 75 to move upward through the disc 74, thereby separating the annular baffle 75 from the container 71. The disc 74 drives the L-shaped mesh plate 78 to separate from the container 71 through the slip ring 77, so that the annular baffle 75 and the L-shaped mesh plate 78 will not interfere with each other during the process of the container 71 being removed from the washing tank 4.

[0034] During the rotation of the rotating rod 76, the rotating rod 76 drives the star-shaped groove ring 81 to rotate. The star-shaped groove of the star-shaped groove ring 81 pushes the L-shaped column rod 82 to reciprocate along the top of the inner wall of the washing tank 4. Each time the L-shaped column rod 82 moves towards the inner wall of the washing tank 4, the L-shaped column rod 82 pushes the hinge rod 83 to drive the vertical rod 84 to move downward along the inner wall of the washing tank 4, and the spring corresponding to the vertical rod 84 is compressed. During the downward movement of the vertical rod 84, it will drive the pressure plate 86 to move downward through the semi-circular rod 85. The pressure plate 86 drives the sponge block 87 to move downward until the sponge block 87 contacts the top of the filter screen 6. As the pressure plate 86 continues to move, the pressure plate 86 will squeeze the sponge block 87. The water absorbed by the sponge block 87 will be squeezed onto the filter screen 6. The water forms a thin film on the filter screen 6. This thin film can help the filter screen 6 capture and adhere to the solids contained in the VOC gas. For particulate impurities, moisture acts as an "adsorbent," enhancing the adhesion of filter screen 6 to solid particles in VOC gas, thereby improving the filtration efficiency of filter screen 6. Simultaneously, as water squeezed out by sponge block 87 enters filter screen 6, some of the solid particulate impurities on the surface of filter screen 6 are washed or rinsed away. Especially after long-term use, this cleaning effect helps maintain the regenerative capacity of filter screen 6, thus reducing the impact of long-term impurity accumulation. Furthermore, each time the semi-circular rod 85 moves the pressure plate 86 downwards, the pressure plate 86 moves the friction rod 88 accordingly. Under the frictional force between the friction rod 88 and the friction ring 89, the friction rod 88 causes the friction ring 89 to rotate. The friction ring 89 then causes the spray pipe 53 to rotate at the horizontal branch of the L-shaped pipe 52. The rotation of the spray pipe 53 allows the liquid to be evenly distributed within the washing tank 4.

[0035] Please see Figures 1-11Based on the above embodiments, in another embodiment of the present invention, an injection device 9 is provided at the disc 74. The injection device 9 includes a flower groove ring 96 and two U-shaped plates 91. The flower groove ring 96 is fixed to the top of the sliding ring 77 by a bracket. A flower groove is fixed to the bottom of the flower groove ring 96. The two U-shaped plates 91 are respectively fixed to the top two sides of the disc 74. A folding bag 92 is fixed to the side of the two U-shaped plates 91 that is close to each other. A sliding plate 93 is fixed to the side of the two folding bags 92 that is close to each other. The sliding plate 93 is slidably mounted on the top of the disc 74. A round block 95 is fixed to the top of the sliding plate 93. The round block 95 is slidably mounted inside the flower groove of the flower groove ring 96. A one-way air inlet 94 is fixed to the side of the two sliding plates 93 that is close to each other. A bottom of the U-shaped plate 91 is fixed with A one-way jet pipe 97 extends through the top of the disc 74. The one-way air inlet 94 controls the one-way air intake of the pleated bladder 92, and the one-way jet pipe 97 controls the one-way air exhaust of the pleated bladder 92. With the above structure, the slide plate 93 squeezes the pleated bladder 92. The VOC gas absorbed in the pleated bladder 92 and purified by the VOC treatment agent is sprayed into the VOC treatment agent in the container 71 through the one-way jet pipe 97. The purified VOC gas is reintroduced into the VOC treatment agent, which helps the VOC treatment agent to continue to play a purifying role. This can improve the utilization efficiency of the VOC treatment agent, especially when treating VOC gas components that are difficult to remove. Through continuous treatment, the VOC treatment agent can more effectively decompose or adsorb the remaining pollutants.

[0036] During use, as the rotating rod 76 drives the slip ring 77 to rotate, the slip ring 77 drives the flower groove ring 96 to rotate. The flower groove of the flower groove ring 96 drives the round block 95 to push the slide plate 93 along the top of the disc 74 towards the U-shaped plate 91. The slide plate 93 squeezes the folded bag 92, and the VOC gas absorbed in the folded bag 92 and purified by the VOC treatment agent is sprayed into the VOC treatment agent in the container box 71 through the one-way jet pipe 97. This reintroduces the purified VOC gas into the VOC treatment agent, helping the VOC treatment agent to continue to exert its purification effect. To improve the efficiency of VOC treatment agents, especially when treating VOC gas components that are difficult to remove, continuous treatment allows the VOC treatment agents to more effectively decompose or adsorb the remaining pollutants. It should be noted that when the flower groove of the flower groove ring 96 drives the round block 95 to pull the slide plate 93 along the top of the disc 74 away from the U-shaped plate 91, the slide plate 93 will stretch the folded bag 92. At this time, the folded bag 92 will take in air through the one-way air inlet 94, thereby replenishing the VOC gas inside the folded bag 92 after it has been purified by the VOC treatment agent.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
