Description

Technical Field

[0001] This invention relates to the field of gas deodorization technology, specifically to an intelligent monitoring dual-stage reverse filling absorption deodorization device. Background Technology

[0002] High-efficiency two-stage countercurrent packed absorption and deodorization devices refer to devices where a chemical reaction occurs during absorption, transforming harmful gaseous components into liquid or harmless gases. Currently, the most mature and widely used industrial equipment is the packed tower, especially the countercurrent packed tower. A countercurrent packed tower is a purification device where the cylindrical body is filled with packing material of various shapes, such as annular, corrugated, or hollow spherical. The absorbent is sprayed downwards from the top of the tower onto the packing material, and the gas rises along the gaps between the packing materials. Harmful substances are absorbed through gas-liquid contact.

[0003] An existing patent (publication number: CN120114978A) discloses a high-efficiency dual-stage reverse filling absorption deodorization device, belonging to the field of gas deodorization technology. It includes a treatment box, with an air inlet at the bottom of the outer side of the treatment box and an air outlet at the top of the treatment box. A cleaning component is provided at the bottom of the inner cavity of the treatment box, and a door panel is provided on the outer side of the treatment box below the cleaning component. Two packing materials are fixedly connected to the inner wall of the treatment box.

[0004] Although the application incorporates a cleaning component that enables the device to automatically filter impurities in the gas when polluted gas is introduced into the treatment chamber, and the device can automatically control the rotation of the threaded rod to move the movable plate along the axis of the threaded rod to clean impurities adhering to the filter screen surface and prevent the filter screen from becoming clogged, the solid precipitates generated by the reaction may adhere to the surface of the packing material, causing blockage of the packing pores, affecting the gas-liquid contact area and mass transfer efficiency, and thus reducing the deodorization efficiency. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent monitoring dual-stage reverse filling absorption deodorization device, which solves the problem in existing technologies that cannot clean the solid precipitates generated by the reaction adhering to the surface of the packing material, leading to pore blockage of the packing material, which in turn affects the gas-liquid contact area and mass transfer efficiency, resulting in reduced deodorization efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent monitoring dual-stage reverse filling absorption deodorization device, comprising a support frame and a tank mounted on the support frame, a top cover fixed to the upper surface of the tank, a spray assembly mounted on the surface of the top cover, a treatment chamber fixedly mounted inside the tank, the lower end of the spray assembly penetrating inside the treatment chamber, an annular support plate fixed to the inner wall of the treatment chamber, a droplet elimination plate and filler overlapping the surface of the annular support plate, and the spray assembly positioned above the filler.

[0007] The bottom of the processing chamber has a drain hole, through which a drain pipe passes. An air inlet pipe passes through the side of the drain pipe. An exhaust pipe corresponding to the air inlet pipe is opened on the surface of the top cover. A rotating assembly is installed on the side of the tank body. The rotating assembly is used to adjust the position of the spray assembly. An ultrasonic generator is fixed on the side of the support frame. Utilizing the cavitation effect of ultrasound, the cleaning fluid generates tiny bubbles on the surface of the packing material, which then burst, impacting and peeling off stubborn deposits. Combined with the spray assembly, this can further improve cleaning efficiency, prevent clogging of the packing material pores, and ensure the gas-liquid contact area.

[0008] Furthermore, the spray assembly includes a three-way valve disposed above the top cover. The two sides of the three-way valve are respectively connected to the reaction liquid pipeline and the cleaning liquid pipeline. The lower end of the three-way valve is rotatably connected to a first connecting pipe. The lower end of the first connecting pipe is fixed with a rotating plate. The rotating plate passes through the inside of the processing chamber. A flow guiding cavity is opened inside the rotating plate. A water permeable hole is opened on the lower surface of the rotating plate. The water permeable hole is connected to the flow guiding cavity.

[0009] With the above scheme, when deodorization is required, the three-way valve opens the reaction liquid pipeline, and the reaction liquid enters the guide cavity of the rotating plate through the first connecting pipe. Then, it is evenly sprayed onto the surface of the packing material below through the water permeable holes, and reacts chemically with the rising gas to achieve the deodorization effect.

[0010] Furthermore, a mounting block is fixed on the upper surface of the rotating plate, an electric actuator is fixed inside the mounting block, a baffle is fixed at the output end of the electric actuator, the baffle moves within the flow guiding cavity via the electric actuator, a flexible hose is inserted through the side of the rotating plate, a high-pressure nozzle is hinged to the lower surface of the rotating plate, the other end of the flexible hose is connected to the high-pressure nozzle, there are multiple high-pressure nozzles, and the angle of each high-pressure nozzle is different.

[0011] With the above method, when the packing needs to be cleaned, the electric actuator pushes the baffle to move in the guide cavity to block the water permeable hole. At this time, the three-way valve switches to the cleaning fluid pipeline. The cleaning fluid enters the hose through the guide cavity and then forms an all-round high-pressure water flow through multiple high-pressure nozzles at different angles to rinse the surface of the packing, thereby removing the sediment attached to the packing.

[0012] Furthermore, the position of the hose corresponds to that of the baffle, and the upper surface and side surface of the baffle are in contact with the flow guide cavity. A balance block is also fixed on the upper surface of the rotating plate relative to the other side of the mounting block.

[0013] With the above solution, the baffle fits snugly against the flow guide cavity, completely covering the water permeable holes and preventing the cleaning fluid from flowing out of the holes. This allows the cleaning fluid to be guided through the hose to the high-pressure nozzle, improving the pressure and effect of high-pressure rinsing. At the same time, the balance block can keep the rotating plate stable during rotation, preventing the rotating plate from tilting or getting stuck due to the shift of the center of gravity.

[0014] Furthermore, the rotating assembly includes a fixing plate fixed to the upper surface of the support frame. The side of the fixing plate is in contact with the tank body. A motor is fixedly installed on the upper surface of the fixing plate. A rotating rod is fixed to the output end of the motor. The other end of the rotating rod passes through the interior of the processing chamber, and a bevel gear is fixed to the other end of the rotating rod. A toothed ring that meshes with the bevel gear is fixed to the upper surface of the rotating plate. The rotating plate moves above the packing through the rotating assembly. The surfaces of the bevel gear and the toothed ring are waterproofed.

[0015] The above scheme uses a motor to drive a rotating rod and bevel gear to rotate, which in turn drives a rotating plate to rotate around the first connecting pipe in the treatment chamber. Combined with multi-angle high-pressure nozzles, the packing material can be rinsed without dead angles. The cavitation effect generated by the ultrasonic generator further enhances the removal effect of sediment in the pores of the packing material. The bevel gear and tooth ring surfaces are waterproofed to prevent the liquid in the treatment chamber from corroding the transmission components.

[0016] Furthermore, a second connecting pipe is fixed to the other end of the air intake pipe, and a fixing ring is fixed to the other end of the second connecting pipe. A support rod is fixed to the upper surface of the fixing ring, and a flow divider is fixed to the upper end of the support rod. The fixing ring is a hollow tube, and an air outlet is opened on the surface of the fixing ring. The flow divider is used to block the air outlet.

[0017] With the above scheme, the gas to be treated enters the second connecting pipe through the inlet pipe, then flows into the hollow fixed ring, and is evenly discharged upward through the outlet holes on the surface of the fixed ring. The diverter plate is located directly above the fixed ring, which can disperse the gas discharged from the outlet holes, avoiding the gas from directly impacting the bottom of the packing and causing excessive local airflow. This allows the gas to be evenly dispersed to the bottom space of the treatment chamber and rise through the gaps in the packing to contact the reaction liquid sprayed from above. At the same time, the diverter plate can also prevent the reaction liquid and cleaning liquid from dripping directly from the outlet holes of the fixed ring into the inlet pipe, preventing liquid backflow from affecting the gas intake efficiency.

[0018] Furthermore, an insulation layer is provided inside the tank, and an inlet pipe and an outlet pipe are respectively installed on both sides of the tank. The position of the insulation layer corresponds to the filler.

[0019] Through the above solution, the insulation layer can reduce the interference of external ambient temperature on the reaction conditions inside the treatment chamber, ensuring that the deodorization reaction is carried out in a stable temperature environment, thereby guaranteeing the stability and consistency of the deodorization effect.

[0020] Furthermore, a gas flow rate sensor is installed on the inner wall of the processing chamber. The gas flow rate sensor is electrically connected to the controller to monitor the gas flow rate in the gap between the packing materials in real time. When the gas flow rate is detected to be lower than the set threshold, the controller triggers the ultrasonic generator to start, and at the same time, the rotating component and the spray component are switched to the cleaning mode. The electric push rod pushes the baffle to block the water permeable hole, and the three-way valve switches to the cleaning fluid pipeline to realize automatic cleaning of the packing materials.

[0021] Furthermore, the exhaust pipe is equipped with an odor gas concentration sensor, which is electrically connected to the controller to detect the content of odor components in the treated gas in real time. When the detected concentration is higher than the set standard, the controller adjusts the spray volume of the reaction liquid of the spray assembly to increase the supply of reaction liquid. At the same time, it controls the rotating assembly to drive the rotating plate to rotate at a low speed so that the reaction liquid evenly covers the surface of the packing material and improves the gas-liquid reaction efficiency.

[0022] Furthermore, a temperature sensor is installed on the inner wall of the processing chamber. The temperature sensor is electrically connected to the controller to monitor the reaction temperature inside the chamber in real time. The temperature sensor data is fed back to the controller, which then activates the inlet and outlet pipes of the tank. When the temperature is below the suitable reaction range, hot water is introduced into the inlet pipe, which transfers heat through the insulation layer to raise the temperature. When the temperature is above the suitable range, cold water is introduced into the inlet pipe to absorb the reaction heat and lower the temperature, thus maintaining a stable reaction temperature.

[0023] Compared with the prior art, the technical solution of the present invention has the following beneficial effects: This intelligent monitoring dual-stage reverse filling absorption deodorization device works by using an electric actuator to push a baffle to block the water-permeable holes when the packing needs cleaning. The three-way valve switches to the cleaning fluid pipeline, and the cleaning fluid is sprayed out from the multi-angle high-pressure nozzles through the guide chamber and hose. At the same time, the motor drives the rotating plate to rotate through the bevel gear and gear ring, so that the high-pressure water flow can wash the surface of the packing without dead angles. Combined with the cavitation effect generated by the ultrasonic generator, the cleaning fluid forms micro bubbles on the surface of the packing and breaks them, thereby impacting and peeling off the sediment, avoiding blockage of the packing pores, and improving the gas-liquid contact area and mass transfer efficiency.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1-4 The intelligent monitoring dual-stage reverse filling absorption deodorization device in this embodiment includes a support frame 1 and a tank 2 installed on the support frame 1. A top cover 3 is fixed on the upper surface of the tank 2, and a spray assembly 4 is installed on the surface of the top cover 3. A treatment chamber 201 is fixedly installed inside the tank 2. The lower end of the spray assembly 4 passes through the inside of the treatment chamber 201. An annular support plate 203 is fixed on the inner wall of the treatment chamber 201. A mist elimination plate 9 and a filler 10 overlap on the surface of the annular support plate 203. The spray assembly 4 is positioned above the filler 10. A drain hole 202 is opened at the bottom of the treatment chamber 201. The inside of the drain hole 202... A drain pipe 5 is installed, and an air inlet pipe 6 is installed on the side of the drain pipe 5. An exhaust pipe 7 corresponding to the air inlet pipe 6 is opened on the surface of the top cover 3. A rotating component 8 is installed on the side of the tank body 2. The rotating component 8 is used to adjust the position of the spray component 4. An installation plate 11 is fixed on the side of the support frame 1. An ultrasonic generator 12 is fixed on the side of the installation plate 11. The ultrasonic cavitation effect causes the cleaning liquid to generate tiny bubbles on the surface of the filler 10 and break them, impacting and peeling off stubborn deposits. Combined with the spray component 4, it can further improve the cleaning efficiency, avoid clogging of the pores of the filler 10, and ensure the gas-liquid contact area.

[0028] Please see Figure 2 and Figure 4 The spray assembly 4 includes a three-way valve 401 located above the top cover 3. The two sides of the three-way valve 401 are connected to a reaction liquid pipeline and a cleaning liquid pipeline, respectively. A first connecting pipe 402 is rotatably connected to the lower end of the three-way valve 401. A rotating plate 403 is fixed to the lower end of the first connecting pipe 402. The rotating plate 403 is inserted inside the treatment chamber 201. A guide cavity 404 is formed inside the rotating plate 403. Water permeable holes 405 are formed on the lower surface of the rotating plate 403 and are connected to the guide cavity 404. When deodorization is required, the three-way valve 401 opens the reaction liquid pipeline. The reaction liquid enters the guide cavity 404 of the rotating plate 403 through the first connecting pipe 402, and then is evenly sprayed onto the surface of the packing 10 below through the water permeable holes 405. It then reacts chemically with the rising gas to achieve deodorization. An mounting block 406 is fixed to the upper surface of the rotating plate 403. An electric actuator 407 is fixed inside the packing block 406. A baffle 408 is fixed at the output end of the electric actuator 407. The baffle 408 moves inside the guide cavity 404 via the electric actuator 407. A flexible hose 409 is inserted through the side of the rotating plate 403. A high-pressure nozzle 410 is hinged to the lower surface of the rotating plate 403. The other end of the flexible hose 409 is connected to the high-pressure nozzle 410. There are multiple high-pressure nozzles 410, and the angle of each high-pressure nozzle 410 is different. When it is necessary to clean the packing 10, the electric actuator 407 pushes the baffle 408 to move in the guide cavity 404 to block the water permeable hole 405. At this time, the three-way valve 401 switches to the cleaning fluid pipeline. The cleaning fluid enters the flexible hose 409 through the guide cavity 404 and then forms an all-round high-pressure water flow through multiple high-pressure nozzles 410 at different angles to rinse the surface of the packing 10, thereby removing the sediment attached to the packing 10.

[0029] In addition, please see Figure 2 and Figure 4 The position of the hose 409 corresponds to that of the baffle 408, and the upper surface and side of the baffle 408 are in contact with the guide cavity 404. A balance block is also fixed on the upper surface of the rotating plate 403 on the other side of the mounting block 406. The baffle 408 is in contact with the guide cavity 404, which can completely cover the water hole 405, preventing the cleaning fluid from flowing out of the water hole 405. The cleaning fluid is guided through the hose 409 to the high-pressure nozzle 410, which improves the pressure and effect of high-pressure rinsing. At the same time, the balance block can keep the rotating plate 403 stable during rotation, preventing the rotating plate 403 from tilting or getting stuck due to the shift of the center of gravity.

[0030] Please see Figure 2The rotating assembly 8 includes a fixed plate 801 fixed to the upper surface of the support frame 1. The side of the fixed plate 801 is in contact with the tank body 2. A motor 802 is fixedly installed on the upper surface of the fixed plate 801. A rotating rod 803 is fixed to the output end of the motor 802. The other end of the rotating rod 803 passes through the processing chamber 201, and a bevel gear 804 is fixed to the other end of the rotating rod 803. A gear ring 805 that meshes with the bevel gear 804 is fixed to the upper surface of the rotating plate 803. The rotating plate 803 moves above the packing 10 through the rotating assembly 8. The bevel gear 804 and the gear ring 805 mesh with the bevel gear 804. The surface of ring 805 is waterproofed. Motor 802 drives rotating rod 803 and bevel gear 804 to rotate, thereby driving rotating plate 403 to rotate in treatment chamber 201 around the first connecting pipe 402. With the help of multi-angle high-pressure nozzle 410, the packing 10 can be rinsed without dead angles. Combined with the cavitation effect generated by ultrasonic generator 12, the removal effect of sediment in the pores of packing 10 is further enhanced. The surface of bevel gear 804 and toothed ring 805 is waterproofed to prevent the liquid in treatment chamber 201 from corroding the transmission components.

[0031] Please see Figure 2 and Figure 3 The other end of the intake pipe 6 is fixed with a second connecting pipe 601, and the other end of the second connecting pipe 601 is fixed with a fixing ring 602. A support rod 603 is fixed on the upper surface of the fixing ring 602, and a flow divider 604 is fixed on the upper end of the support rod 603. The fixing ring 602 is a hollow tube, and an exhaust hole 605 is opened on the surface of the fixing ring 602. The flow divider 604 is used to block the exhaust hole 605. The gas to be treated enters the second connecting pipe 601 through the intake pipe 6, and then flows into the hollow fixing ring 602, and passes through the exhaust hole opened on the surface of the fixing ring 602. The gas is discharged evenly upwards from the outlet 605. The diverter plate 604 is located directly above the fixed ring 602. It can disperse the gas discharged from the outlet 605, preventing the gas from directly impacting the bottom of the packing 10 vertically upwards and causing excessive local airflow. This allows the gas to be evenly dispersed to the bottom space of the treatment chamber 201 and rise through the gaps in the packing 10 to contact the reaction liquid sprayed from above. At the same time, the diverter plate 604 can also prevent the reaction liquid and cleaning liquid from dripping directly from the outlet 605 of the fixed ring 602 into the air inlet pipe 6, preventing liquid backflow from affecting the air intake efficiency.

[0032] It should be noted that an insulation layer 204 is also provided inside the tank body 2. Water inlet pipe and water outlet pipe are respectively installed on both sides of the tank body 2. The position of the insulation layer 204 corresponds to the packing 10. The insulation layer 204 can reduce the interference of the external ambient temperature on the reaction conditions inside the treatment chamber 201, ensure that the deodorization reaction is carried out in a stable temperature environment, and thus ensure the stability and consistency of the deodorization effect.

[0033] In this invention, a gas flow rate sensor is provided on the inner wall of the processing chamber 201. The gas flow rate sensor is electrically connected to the controller to monitor the gas flow rate in the gap of the packing 10 in real time. When the gas flow rate is detected to be lower than the set threshold, the controller triggers the ultrasonic generator 12 to start, and at the same time, the rotating component 8 and the spray component 4 are switched to the cleaning mode. The electric push rod 407 pushes the baffle 408 to block the water permeable hole 405, and the three-way valve 401 switches to the cleaning fluid pipeline to realize the automatic cleaning of the packing 10.

[0034] In this invention, an odor gas concentration sensor is installed inside the exhaust pipe 7. The odor gas concentration sensor is electrically connected to the controller to detect the content of odor components in the treated gas in real time. When the detected concentration is higher than the set standard, the controller adjusts the spray volume of the reaction liquid of the spray assembly 4 to increase the supply of reaction liquid. At the same time, the controller controls the rotating assembly 8 to drive the rotating plate 403 to rotate at a low speed so that the reaction liquid evenly covers the surface of the packing 10 and improves the gas-liquid reaction efficiency.

[0035] In this invention, a temperature sensor is installed on the inner wall of the processing chamber 201. The temperature sensor is electrically connected to the controller to monitor the reaction temperature inside the chamber in real time. The temperature sensor data is fed back to the controller, which then links the inlet and outlet pipes of the tank 2. When the temperature is below the suitable reaction range, hot water is introduced into the inlet pipe, and heat is transferred through the insulation layer 204 to raise the temperature. When the temperature is above the suitable range, cold water is introduced into the inlet pipe to absorb the reaction heat and lower the temperature, thus maintaining a stable reaction temperature.

[0036] The working principle of the above embodiments is as follows: First, place the device in a suitable location and connect it to an external power source and control equipment. The control equipment is a known conventional device such as a controller or computer with control functions. Then, the operator connects the two ends of the three-way valve 401 to the reaction liquid pipeline and the cleaning liquid pipeline, respectively, and connects the air inlet pipe 6 to the gas pipeline to be treated. The operator then controls the overall operation of the device through the control equipment.

[0037] The gas to be treated enters the treatment chamber 201 through the inlet pipe 6 at the bottom of the tank 2. At the same time, the reaction liquid enters the first connecting pipe 402 through the three-way valve 401. It is then evenly sprayed onto the surface of the packing 10 through the water permeable hole 405 through the guide cavity 404 inside the rotating plate 403. At this time, the electric actuator 407 is in the initial state, and the baffle 408 is located in the upper part of the guide cavity 404, blocking the inlet end of the hose 409. This allows the reaction liquid to be discharged through the water permeable hole 405 and fully contact the rising gas in the packing 10 layer. Utilizing the principle of gas-liquid countercurrent flow, the reaction liquid reacts chemically with the odorous components in the gas to be treated, thereby achieving deodorization. The deodorized gas continues to move upward. After the droplet elimination plate 9 removes the carried droplets, it is discharged from the device through the exhaust pipe 7 opened on the surface of the top cover 3. The reaction liquid after the reaction flows into the drain pipe 5 through the drain hole 202 at the bottom of the treatment chamber 201.

[0038] When it is necessary to clean the solid deposits adhering to the surface of the packing 10, the operator controls the ultrasonic generator 12 through the control equipment. The high-frequency vibration generated by the ultrasonic generator 12 is transmitted through the tank 2 to the packing 10 in the treatment chamber 201. Utilizing the cavitation effect of the ultrasound, the solid deposits adhering to the surface of the packing 10 are loosened and detached. At the same time, the control equipment switches the three-way valve 401 to the cleaning fluid pipeline and activates the electric actuator 407, pushing the baffle 408 downward so that the lower surface of the baffle 408 fits against the bottom wall of the guide cavity 404, opening the inlet end of the hose 409, and simultaneously sealing the water permeable hole 405 to allow the cleaning fluid to enter. After entering the guide cavity 404, the water can enter the hose 409 and be sprayed out from the high-pressure nozzle 410 to form a high-pressure water flow. At the same time, the operator controls the motor 802 through the control equipment. The motor 802 drives the rotating rod 803 and the bevel gear 804 fixed at one end of the rotating rod 803 to rotate, thereby driving the gear ring 805 that meshes with it to rotate. The gear ring 805 drives the rotating plate 403 to rotate synchronously, thereby driving the high-pressure nozzle 410 to make a circular motion above the packing 10 to wash the packing 10, wash away the attached sediment, and prevent the pores from being blocked. The wastewater generated during cleaning is discharged through the drain hole 202 and the drain pipe 5 at the bottom of the tank 2.

[0039] During the reaction, when heating is required, hot water is introduced through the inlet pipe to increase the internal temperature through heat transfer between the insulation layer 204 and the processing chamber 201, thus promoting the chemical reaction. When cooling is required, cold water is introduced to absorb the heat released during the reaction, preventing the temperature from being too high and affecting the reaction efficiency or causing equipment damage. The water is discharged through the outlet pipe after use.
