Technical Field
[0001] This utility model relates to the field of recycling devices, and more specifically, to a recycling device for UV monomer exhaust gas. Background Technology
[0002] With the acceleration of industrialization, a large amount of industrial exhaust gas is emitted into the atmosphere, causing serious environmental pollution. Environmental problems such as acid rain and smog are becoming increasingly prominent. Moreover, industrial exhaust gas often contains various valuable components, such as carbon dioxide, sulfur dioxide and carbon monoxide. If these components can be recovered and reused, not only can environmental pollution be reduced, but also resource recycling can be achieved. Thus, traditional gas recovery and utilization devices have emerged. Although traditional condensation gas recovery devices have good recovery efficiency for high-boiling-point gases, their recovery effect for UV exhaust gas with low boiling point is not ideal, and they also consume a lot of cooling energy.
[0003] A search revealed that publication number CN214513452U discloses a UV single-cell exhaust gas recycling device, comprising an exhaust gas chamber and a reaction chamber. A conduit is fixedly installed on one side of the exhaust gas chamber, penetrating the reaction chamber. A sealing plate is rotatably installed on one side of the reaction chamber. A recycling device is fixedly installed inside the reaction chamber, comprising a water tank, a connecting pipe, a leak, a support rod, an adhesion plate, a perforation, a connecting rod, and a rotating block. By opening a valve on the conduit, the exhaust gas in the exhaust gas chamber flows through the conduit into the connecting pipe, and then is discharged into the water tank through the leak. The gas and water contact to form bubbles, which then contact the adhesion plate, causing impurities in the gas to adhere to the plate. The impurities adhering to the adhesion plate are scraped off and collected. An activated carbon adsorption device is installed on the plate. By pulling the storage box, a slider moves along a chute, removing the saturated activated carbon from the storage box for recycling the organic waste gas. The inventors discovered the following problems with the existing technology during the development of this utility model:
[0004] When existing gas recovery and utilization devices directly separate and recover exhaust gas, solid particles mixed in the exhaust gas can cause blockages in the internal parts of the recovery device, and some sharp solid metal particles can cause wear on the surface of the parts, thus affecting its normal operation. In addition, some exhaust gas also contains oil stains. After these oil stains enter the recovery device along with the exhaust gas, they will adhere to the surface of its internal parts. Since the gas recovery and utilization device needs to separate and recover the gas in a closed area, it is also difficult to clean the internal parts with oil stains.
[0005] Therefore, a recycling device for UV generator exhaust gas is proposed to address the above-mentioned problems. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for recycling and recovering exhaust gas from UV cells, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for recycling and utilizing UV monomer exhaust gas, comprising a main component, a filter component, a membrane component, a monitoring component, and an adjustment component. An adjustment component is installed on the side of the filter component, and the main component is installed on the side of the adjustment component away from the filter component. A membrane component is placed on the inner wall of the main component, and a monitoring component is placed on top of the membrane component.
[0008] Preferably, the filter assembly includes a filter element, a retaining ring, and an oil adsorption layer, wherein the retaining ring is installed on the outer diameter surface of the filter element, and the oil adsorption layer is placed on the side of the filter element.
[0009] Preferably, the membrane assembly includes a recycling membrane, a pull plate, a cross plate, and a threaded connecting post, wherein the pull plate is installed on the outer diameter surface of the recycling membrane, the cross plate is installed above the pull plate, and the threaded connecting post is installed above the cross plate.
[0010] Preferably, the monitoring component includes a first pressure sensor, a second pressure sensor, and a temperature sensor, with the second pressure sensor placed above the first pressure sensor and the temperature sensor placed to the side of the first pressure sensor.
[0011] Preferably, the regulating assembly includes a heat exchanger, a booster pump, and a pressure reducing valve, with the booster pump placed on the side of the heat exchanger and the pressure reducing valve placed above the booster pump.
[0012] Preferably, the main component includes a separation tower, a sealing rubber gasket, and an anti-loosening component, and the anti-loosening component is installed on the side of the separation tower, and the sealing rubber gasket is installed on the side of the anti-loosening component away from the separation tower.
[0013] Preferably, the anti-loosening component includes a first anti-loosening washer, a second anti-loosening washer, and a fixing bolt, wherein the first anti-loosening washer is placed on the outer diameter surface of the fixing bolt, and the second anti-loosening washer is placed on the side of the first anti-loosening washer.
[0014] Preferably, the separation tower includes an inlet valve, an outlet valve, and a tower body, with the tower body mounted on the side of the inlet valve and the outlet valve mounted on the side of the tower body away from the inlet valve.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1. Compared with the existing technology, the recycling device for UV monomer exhaust gas first filters the exhaust gas entering the main component through the filter component, so that solid particles and oil stains inside the exhaust gas can be cleaned outside the main component, thereby protecting the parts inside the main component and reducing the frequency of cleaning the inside of the main component by workers.
[0017] 2. Compared with existing technologies, this recycling and reuse device for UV monomer exhaust gas features a quick-replacement membrane module design, allowing workers to quickly replace the recovery membrane. This ensures that the plant's exhaust gas collection process is not delayed due to membrane malfunction. When workers need to inspect or replace the membrane module, they must first separate the sealing rubber gasket from the separation tower and loosen the fixing bolts of the anti-loosening component using a wrench. Then, the first and second anti-loosening gaskets are removed together. At this point, workers need to use a threaded rod that matches the threaded connecting column to connect with the threaded connecting column. By pulling the threaded rod, the threaded connecting column moves the cross plate upward. The cross plate and the pulling plate are connected by bolts, so the pulling plate slides upward together with the cross plate in the groove of the main component, pulling the recovery membrane out of the main component. At this point, workers only need to unfasten the buckle between the recovery membrane and the pulling plate to remove the recovery membrane. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] As attached Figures 1 to 4 The device shown for recycling and recovering UV single-cell exhaust gas includes a main component 1, a filter component 2, a membrane component 3, a monitoring component 4, and an adjustment component 5. The adjustment component 5 is installed on the side of the filter component 2. The main component 1 is installed on the side of the adjustment component 5 away from the filter component 2. The membrane component 3 is placed on the inner wall of the main component 1. The monitoring component 4 is placed on top of the membrane component 3.
[0026] Specifically, when workers need to filter and recover the UV monomer exhaust gas, they must first connect the collection box for collecting the UV monomer exhaust gas to the connecting pipe on the outside of the filter assembly 2 via a pipe. Then, they open the connecting valve at this point, allowing the exhaust gas to enter the filter assembly 2 from the collection box. The exhaust gas entering the filter assembly 2 will have solid particles and oil stains filtered out to prevent the stains from damaging the main assembly 1. The filtered exhaust gas will then flow up the filter assembly 2 and into the pipe connected to the regulating assembly 5. At this time, the connecting valve at this point will be opened, and the regulating assembly 5 will heat or cool the exhaust gas coming out of the filter assembly 2 to ensure that its temperature meets the optimal temperature for gas permeation of the membrane assembly 3. After passing through the regulating component 5, the exhaust gas enters the main component 1 and moves upward from the bottom of the main component 1. During this process, it passes through the membrane component 3, which filters the exhaust gas. Exhaust gas that meets the requirements continues to move upward through the membrane component 3 and is discharged from the main component 1 into the storage tank through the exhaust pipe above the main component 1. Exhaust gas that does not meet the requirements is intercepted below the membrane component 3. During this process, the air pressure below the membrane component 3 continuously increases. The monitoring component 4 monitors the air pressure and temperature at the top and bottom of the membrane component 3 in real time and adjusts them accordingly. This ensures that the membrane component 3 can function normally while achieving efficient recovery of the required portion of the exhaust gas.
[0027] Example 2
[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:
[0029] In a preferred embodiment, the filter assembly 2 includes a filter element 6, a fixing ring 7, and an grease adsorption layer 8. The fixing ring 7 is installed on the outer diameter surface of the filter element 6, and the grease adsorption layer 8 is placed on the side of the filter element 6. When the exhaust gas passes through the filter assembly 2, it will first pass through the filter element 6, which is fixed to the inner wall of the filter housing by the fixing ring 7, and the solid particles in the exhaust gas will be filtered out in the filter element 6. The exhaust gas with the solid particles filtered out will move upward and be adsorbed by the grease adsorption layer 8, thereby protecting the main assembly 1.
[0030] In a preferred embodiment, the membrane module 3 includes a recyclable membrane 9, a pull plate 10, a cross plate 11, and a threaded connecting post 12. The pull plate 10 is installed on the outer diameter surface of the recyclable membrane 9, and the pull plate 10 and the recyclable membrane 9 are connected by a snap-fit. The cross plate 11 is installed above the pull plate 10, and the threaded connecting post 12 is installed above the cross plate 11. When the worker needs to inspect or replace the membrane module 3, he needs to open the main component 1, and then connect the threaded rod to the threaded connecting post 12 through a threaded connection. Then, by pulling the threaded rod, the threaded connecting post 12 drives the cross plate 11 to move upward. The cross plate 11 and the pull plate 10 are connected by bolts, so the pull plate 10 will move upward together with the cross plate 11 in the groove of the main component 1, and drive the recyclable membrane 9 out of the main component 1.
[0031] In a preferred embodiment, the monitoring component 4 includes a first pressure sensor 13, a second pressure sensor 14, and a temperature sensor 15. The second pressure sensor 14 is placed above the first pressure sensor 13, and the temperature sensor 15 is placed to the side of the first pressure sensor 13. The first pressure sensor 13 and the second pressure sensor 14 are both BMP388 models. They utilize the piezoresistive effect; when air pressure acts on a resistor mounted on a diaphragm, the resistance value changes. The pressure sensor then uses a Wheatstone bridge circuit to convert the resistance change into a voltage signal output and calculates the air pressure value by measuring the voltage change. The temperature sensor 15 is a PT100 model. It changes its own resistance value based on the external temperature, and the resistance value changes the magnitude of the internal electrical signal of the sensor. The electrical signal is then transmitted to the connected microcontroller and finally transmitted to the outside in the form of a digital signal.
[0032] In a preferred embodiment, the regulating component 5 includes a heat exchanger 16, a booster pump 17, and a pressure reducing valve 18. The booster pump 17 is placed on the side of the heat exchanger 16, and the pressure reducing valve 18 is placed above the booster pump 17. The exhaust gas from the filter component 2 enters the heat exchanger 16 and is heated or cooled before entering the main component 1. When the gas pressure in the main component 1 is low, preventing the exhaust gas from passing smoothly through the membrane component 3, the worker needs to use the booster pump 17 to pressurize the inside of the main component 1. When the pressure is high, the worker needs to open the pressure reducing valve 18 to prevent damage to the internal parts of the main component 1 due to the high air pressure. The heat exchanger 16 is model BES-800. High-temperature gas enters the tube side or shell side from the air inlet of the heat exchanger 16. At the same time, the cooling medium enters the other side channel from the cooling medium inlet under the action of the pump or fan and circulates. The two exchange heat through the tube wall. The high-temperature gas is cooled down by the heat transferred to the cooling medium and then discharged into the main component 1 through the air outlet. The cooling medium, which has absorbed heat and heated up, is discharged from the outlet.
[0033] In a preferred embodiment, the main body assembly 1 includes a separation tower 19, a sealing rubber gasket 20, and an anti-loosening component 21. The anti-loosening component 21 is installed on the side of the separation tower 19, and the sealing rubber gasket 20 is installed on the side of the anti-loosening component 21 away from the separation tower 19. When a worker needs to remove the membrane assembly 3 from the separation tower 19, he / she needs to separate the sealing rubber gasket 20 from the separation tower 19 and then twist the anti-loosening component 21 so that the worker can take out the membrane assembly 3 from the main body assembly 1.
[0034] In a preferred embodiment, the anti-loosening assembly 21 includes a first anti-loosening washer 22, a second anti-loosening washer 23, and a fixing bolt 24. The first anti-loosening washer 22 is placed on the outer diameter surface of the fixing bolt 24, and the second anti-loosening washer 23 is placed on the side of the first anti-loosening washer 22. When disassembling the anti-loosening assembly 21, the worker needs to use a wrench to loosen the fixing bolt 24, and then remove the first anti-loosening washer 22 and the second anti-loosening washer 23 together.
[0035] In a preferred embodiment, the separation tower 19 includes an inlet valve 25, an outlet valve 26, and a tower body 27. The tower body 27 is mounted on the side of the inlet valve 25, and the outlet valve 26 is mounted on the side of the tower body 27 away from the inlet valve 25. The inlet valve 25 and the tower body 27 are connected by a flange, and the outlet valve 26 and the tower body 27 are connected by a flange. After the exhaust gas enters the tower body 27 through the inlet valve 25, it will pass through the membrane module 3, and the exhaust gas passing through the membrane module 3 will be discharged from the outlet valve 26 and enter the storage tank.
[0036] The working process of this utility model is as follows: First, when the worker needs to filter and recover the UV monomer exhaust gas, they need to first connect the collection box for collecting the UV monomer exhaust gas to the connecting pipe on the outside of the filter assembly 2 via a pipe. Then, open the connecting valve at this point to allow the exhaust gas to enter the filter assembly 2 from the collection box. The exhaust gas entering the filter assembly 2 will first pass through the filter element 6, which is fixed to the inner wall of the filter housing by the fixing ring 7, and the solid particles in the exhaust gas will be filtered out in the filter element 6. The exhaust gas with the solid particles removed will move upward and be adsorbed in the grease adsorption layer 8. Oil stains are filtered out, thus protecting the main component 1 and preventing damage to it. The filtered exhaust gas will enter the pipe connected to the regulating component 5 from the top of the filter component 2. At this time, the connection valve will be opened, and the heat exchanger 16 of the regulating component 5 will heat or cool the exhaust gas from the filter component 2 to make its temperature meet the optimal temperature for gas permeation of the membrane component 3. After the exhaust gas passes through the heat exchanger 16, it will enter the main component 1 through the air inlet valve 25 of the separation tower 19, and it will move upward from the bottom of the tower body 27.
[0037] During this process, the exhaust gas passes through the recovery membrane 9 of membrane module 3. Membrane module 3 filters the exhaust gas; the qualified exhaust gas continues to move upward through recovery membrane 9 and is discharged into the storage tank through the exhaust pipe on the side of exhaust valve 26. The unqualified exhaust gas is intercepted below membrane module 3. During this process, the air pressure below membrane module 3 continuously increases. The second and first sensors of monitoring module 4 monitor the air pressure at the top and bottom of membrane module 3 in real time and transmit the air pressure data in the main component 1 to the staff. The staff analyzes the air pressure in the area below membrane module 3. When the air pressure in this area is low, the efficiency of the exhaust gas passing through recovery membrane 9 is... If the pressure is too high, the worker needs to start the booster pump 17 to pressurize the internal components of the main body 1. When the internal pressure is too high, in order to prevent the internal parts from being damaged due to excessive pressure, the worker needs to open the pressure reducing valve 18 to reduce the internal pressure. This allows for efficient recovery of the exhaust gas while ensuring that the membrane assembly 3 can work normally. The temperature sensor 15 can monitor the temperature of the area near the recovery membrane 9 in real time. When the temperature of this area is too high, it will damage the recovery membrane 9. If it is too low, it will slow down the rate at which the exhaust gas passes through the recovery membrane 9. At this time, the worker needs to adjust the heat exchanger 16 to adjust the temperature of the exhaust gas entering the main body 1 in a timely manner.
[0038] When workers need to inspect or replace membrane module 3, they need to open the main assembly 1, then separate the sealing rubber gasket 20 from the separation tower 19, and loosen the fixing bolt 24 of the anti-loosening assembly 21 by wrench. Then, the first anti-loosening gasket 22 and the second anti-loosening gasket 23 are removed together. At this time, workers need to use the threaded rod matched with the threaded connecting column 12 to connect with the threaded connecting column 12 by threaded connection. Then, by pulling the threaded rod, the threaded connecting column 12 drives the cross plate 11 to move upward. The cross plate 11 and the pulling plate 10 are connected by bolts, so the pulling plate 10 will be in the groove of the main assembly 1, moving upward together with the cross plate 11 and driving the recovery membrane 9 out of the main assembly 1 for inspection. The above is the working principle of the recycling device for UV monomer exhaust gas.
