Description

Technical Field

[0001] This utility model relates to the field of vacuum insulation filtration and adsorption technology, specifically a double-layer vacuum insulation uniform filtration and adsorption device. Background Technology

[0002] Activated carbon adsorption filtration devices are mainly used for the adsorption and treatment of volatile organic compounds (VOCs) during the production of coal chemical, petrochemical, fuel coating manufacturing, and solvent manufacturing. After a certain period of adsorption treatment, the adsorbent (activated carbon particles) needs to be replaced and desorbed. The desorption treatment of the adsorbent (activated carbon particles) adopts in-situ desorption, and the saturated adsorbent (activated carbon particles) organic waste gas is rapidly desorbed by a mobile thermal oxidation device at high temperature.

[0003] For example, in the prior art, CN216136960U discloses a vacuum-insulated ring speed-changing adsorption device, which mainly uses adsorbent (activated carbon particles) for adsorption treatment, and then regenerates the saturated adsorbent (activated carbon particles) by desorption.

[0004] However, in this technology, the adsorbent (activated carbon granules) is loaded and discharged through multiple feed ports at the top and multiple discharge ports at the bottom. When loading, it is necessary to manually load each feed port to ensure that the adsorbent (activated carbon granules) is loaded evenly. When discharging, because the bottom is flat, the remaining adsorbent (activated carbon granules) cannot be discharged, and it is often necessary to manually go deep into the discharge port to scrape out the remaining material.

[0005] Because the adsorbent (activated carbon particles) is a granular accumulation rather than a dense accumulation, after working for a period of time, the adsorbent (activated carbon particles) will settle. As a result, some of the exhaust gas above will be discharged directly from the settled cavity without being adsorbed by the adsorbent (activated carbon particles), thus affecting the emission indicators.

[0006] Furthermore, since the exhaust path is fixed, the filtered exhaust gas is preferentially discharged from the nearest exhaust port. This results in less adsorption by the adsorbent (activated carbon particles) far from the exhaust port, causing the adsorbent (activated carbon particles) near the exhaust port to quickly become saturated, while the adsorbent (activated carbon particles) far from the exhaust port are not yet saturated, resulting in uneven adsorption by the adsorbent (activated carbon particles).

[0007] Furthermore, the working time of the adsorbent (activated carbon particles) is not permanent; it has a certain lifespan. Generally, the adsorbent (activated carbon particles) needs to be desorbed after working for 500 hours, but current technology cannot record the working time of the adsorbent (activated carbon particles).

[0008] Based on this, the present invention provides a double-layer vacuum heat-insulated uniform filtration and adsorption device to solve the above problems. Utility Model Content

[0009] In view of the above situation and to overcome the defects of the prior art, this utility model provides a double-layer vacuum heat-insulated uniform filtration and adsorption device. This utility model has a novel structure and ingenious design, and effectively solves the technical problems of inconvenient feeding and discharging of existing adsorption devices, direct discharge of waste gas after the adsorbents such as activated carbon and molecular sieves settle, uneven adsorption of activated carbon, and inability to record the working time of activated carbon.

[0013] Preferably, the upper end of the adsorption cylinder is equipped with a plurality of feed pipes placed on the adsorbent mesh cylinder, and a feeding device is detachably installed on the plurality of feed pipes. The feeding device includes a feed hopper, a protruding column is integrally fixed in the center of the feed hopper, and the bottom of the feed hopper is connected to a plurality of feeding pipes that match the feed pipes. The feeding pipes are inserted into the feed pipes.

[0014] Preferably, a temperature sensor is installed inside the adsorption cylinder and placed inside the adsorbent mesh cylinder, an annular spray pipe is installed inside the adsorption cylinder and connected to a water inlet pipe installed on the adsorption cylinder, and a drain pipe is installed at the lower end of the adsorption cylinder.

[0015] Preferably, the adsorption cylinder has a heat-insulating cotton attached to the inner wall of the vacuum chamber, and the outer wall of the adsorption cylinder has a suction pipe connected to the vacuum chamber.

[0016] Preferably, the exhaust pipe is connected to an air extraction device via a duct, and the air extraction device is connected to a timing sensor.

Detailed Implementation

[0033] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 4 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0034] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0035] As one embodiment, this utility model is a vacuum double-layer uniform filtration adsorption device, including an adsorption cylinder 1. The adsorption cylinder 1 has an internal cavity, and a vacuum chamber 2 is reserved in the inner wall of the adsorption cylinder 1. This cavity, called the vacuum chamber 2, is used to discharge air and has a heat insulation function. An adsorbent mesh cylinder 3 is installed inside the adsorption cylinder 1. The adsorbent mesh cylinder 3 consists of two layers of annular mesh screens. The adsorbent, such as activated carbon particles, is placed between the two mesh screens. The two mesh screens are referred to as the inner mesh cylinder and the outer mesh cylinder. The adsorbent (activated carbon particles) is placed between the inner mesh cylinder and the outer mesh cylinder. A filter chamber is formed between the adsorption cylinder 1 and the vacuum chamber 2, and an exhaust gas chamber is formed inside the inner mesh cylinder. An air inlet pipe 4 is installed at the upper end of the adsorption cylinder 1, and the air inlet pipe 4 connects to the exhaust gas chamber. An exhaust pipe 5 is installed on one side of the lower end of the adsorption cylinder 1, which penetrates the vacuum chamber 2. A discharge cylinder 9 is integrally fixed at the lower end of the adsorption cylinder 1, and the discharge cylinder 9 is connected to the lower end of the adsorbent mesh cylinder 3. Multiple discharge ports 10 are opened on the upper part of the discharge cylinder 9. A discharge block 32 is integrally fixed on the discharge cylinder 9 between every two discharge ports 10. The discharge block 32 has a triangular cross section to prevent the adsorbent (activated carbon particles) from accumulating in the equipment.

[0036] After a period of adsorption, the adsorbent (activated carbon granules) will become saturated. Once saturated, the adsorbent (activated carbon granules) needs to be desorbed. Generally, the adsorbent (activated carbon granules) can be desorbed 12-15 times, or after 3 months or 500 hours of continuous operation, the adsorbent (activated carbon granules) should be desorbed.

[0037] When replacing the adsorbent (activated carbon granules), because the bottom of the adsorption cylinder 1 is flat, the adsorbent (activated carbon granules) cannot be completely discharged in the final stage. Each time, the staff needs to put their hands and arms into the adsorption cylinder 1 to scrape out the bottom material of the adsorbent (activated carbon granules).

[0038] This invention, by adding a discharge block 32 with a triangular cross-section and protrusions, enables the adsorbent (activated carbon particles) above to be automatically and quickly discharged, effectively solving the technical problems caused by the material discharge of the equipment.

[0039] As an example, the upper part of the adsorbent mesh cylinder 3 is provided with a non-porous closed baffle plate 8. Specifically, the adsorbent mesh cylinder 3 is composed of an inner mesh cylinder and an outer mesh cylinder. At least one of the inner mesh cylinder or the outer mesh cylinder is provided with a non-porous closed baffle plate 8 at its upper end. The non-porous closed baffle plate 8 is equivalent to not having holes at the upper end of the inner mesh cylinder or the outer mesh cylinder, and having filter mesh holes below it, thereby forming an inner mesh cylinder and an outer mesh cylinder.

[0040] Because the activated carbon filled in the adsorbent mesh cylinder 3 is granular, it is not completely airtight after being filled. As the adsorbent cylinder 1 operates normally, the adsorbent (activated carbon granules) will sink. When the adsorbent (activated carbon granules) sinks, the upper part becomes a cavity. If there is no non-porous sealed baffle plate 8 at this time, the exhaust gas will directly pass through the filter mesh at this point and be discharged without being adsorbed by the adsorbent (activated carbon granules). Therefore, the non-porous sealed baffle plate 8 can prevent the exhaust gas from passing through this part after the adsorbent (activated carbon granules) sinks, so that the exhaust gas can be discharged after being adsorbed by the adsorbent (activated carbon granules) from below.

[0041] As an example, the adsorbent mesh cylinder 3 is rotatably installed inside the adsorption cylinder 1 via a bearing seat. A large gear 33 is fixedly sleeved on the outside of the adsorbent mesh cylinder 3. The large gear 33 meshes with a small gear 6. The small gear 6 coaxially passes through the bottom of the adsorption cylinder 1 and is sealed and connected to the drive motor 7 fixed at the bottom of the adsorption cylinder 1.

[0042] In this embodiment, the adsorbent mesh cylinder 3 is filled with activated carbon particles, the vacuum chamber 2 is evacuated to a vacuum state, and waste gas is introduced through the inlet pipe 4. The exhaust pipe 5 is connected to the exhaust pump 22. The waste gas enters the waste gas chamber through the inlet pipe 4, then passes through the inner mesh cylinder and is adsorbed by the adsorbent (activated carbon particles), and then passes through the outer mesh cylinder to enter the filter chamber.

[0043] Since the filter chamber is annular, the filter chamber closest to the exhaust pipe 5 is the optimal shortcut and will be preferentially sucked away by the suction device 22, while the exhaust gas from the filter chambers in other directions will travel a longer path within the filter chamber before being discharged from the exhaust pipe 5.

[0044] Because the exhaust gas in the filter chamber near the exhaust pipe 5 is preferentially discharged, the adsorbent (activated carbon particles) at this location will adsorb more exhaust gas, causing the adsorbent (activated carbon particles) at this location to be preferentially saturated, resulting in uneven adsorption of the adsorbent (activated carbon particles) in the adsorbent mesh cylinder 3.

[0045] By controlling the drive motor 7, the drive motor 7 controls the small gear 6 to rotate. The small gear 6 meshes with the large gear 33 to reduce speed and rotate. The large gear 33 drives the activated carbon cylinder 3 to rotate, so that the adsorbent (activated carbon particles) in the adsorbent cylinder 3 is in a rotating state. The optimal path for waste gas filtration is fixed. By making the adsorbent (activated carbon particles) rotate, the adsorbent in the adsorbent cylinder 3 is uniformly adsorbed.

[0046] It should be noted that, for easier operation, drive motor 7 is connected to the power supply and controller.

[0047] As an example, to facilitate feeding, six circumferentially distributed feed pipes 11 connected to the adsorbent mesh cylinder 3 are installed at the upper end of the adsorption cylinder 1. The upper end of the feed pipe 11 is designed in a funnel shape, making installation and feeding more convenient. A feeding device is detachably installed on the feed pipe 11. The feeding device includes a feed hopper 12. The inside of the feed hopper 12 is a cavity with an opening at the upper end. A protruding column 13 is integrally fixed at the bottom center of the feed hopper 12 to prevent the adsorbent (activated carbon particles) from accumulating in the middle of the feed hopper 12 during feeding. Six feeding pipes 14 are connected to the bottom of the feed hopper 12. The feeding pipes 14 are matched with the feed pipes 11, and the lower end of the feeding pipes 14 can be inserted into the feed pipes 11.

[0048] When replacing the adsorbent (activated carbon granules), align the feeding pipe 14 of the feeding device with the feeding pipe 11 and fix it. Then, add the adsorbent (activated carbon granules) into the feeding hopper 12 through the feeding device. The adsorbent (activated carbon granules) are quickly and evenly added into the adsorbent mesh cylinder 3 through the 6 feeding pipes 14, without having to feed them into the feeding pipes 11 one by one.

[0049] As an example, a temperature sensor 15 is installed inside the adsorption cylinder 1 and placed inside the adsorbent mesh cylinder 3. The temperature sensor 15 is connected to a controller and is used to detect the temperature of the adsorption cylinder 1.

[0050] When the adsorbent (activated carbon particles) becomes saturated, it needs to be desorbed. During desorption, a high temperature of over 60°C is introduced into the adsorption cylinder 1 through a thermal oxidation moving desorption device. At this high temperature, the organic waste gas in the saturated adsorbent (activated carbon particles) is rapidly desorbed. At the same time, the carbon and water vapor react, the pores further develop, and new active surfaces are formed. The regenerated adsorbent (activated carbon particles) regains its adsorption capacity, reducing the amount of adsorbent (activated carbon particles) used and also reducing the amount of hazardous waste to be disposed of.

[0051] Therefore, during desorption, the temperature sensor 15 can constantly monitor the temperature inside the adsorption cylinder 1 to prevent the temperature from being too high and causing the adsorbent (activated carbon particles) to burn.

[0052] As an example, an annular spray pipe 16 is installed inside the adsorption cylinder 1. Multiple spray heads are connected to the spray pipe 16. The upper end of the spray pipe 16 is connected to a water inlet pipe 17 installed on the adsorption cylinder 1. The water inlet pipe 17 is externally connected to a solenoid valve and a water supply source.

[0053] During desorption, when the temperature is too high and the adsorbent (activated carbon particles) burns, the set temperature is reached, and a signal is sent to the controller. The controller then sends a signal to the solenoid valve, and the water supply source supplies water to the spray pipe 16 through the water inlet pipe 17.

[0054] As an example, a drain pipe 18 is installed at the lower end of the adsorption cylinder 1. Specifically, it can be installed at the lower end of the filter chamber and the lower end of the exhaust gas chamber. After the spray pipe 16 sprays water, the water in the adsorption cylinder 1 needs to be drained. At this time, the spray water is drained through the drain pipe 18 on the filter chamber and the exhaust gas chamber.

[0055] As an example, a heat-insulating cotton 19 is fixedly attached to the outer wall of the vacuum chamber 2 inside the adsorption cylinder 1. The outer wall here does not refer to the inner wall inside the vacuum chamber 2, but to the inner wall of the outer ring of the vacuum chamber 2 placed inside the adsorption cylinder 1. An air extraction pipe 20 communicating with the vacuum chamber 2 is fixed on the outer wall of the adsorption cylinder 1 for vacuuming the vacuum chamber 2.

[0056] The insulation cotton 19 and the vacuum chamber 2 form a double-layer insulation structure to prevent the temperature from dropping due to heat dissipation during the desorption process, which would affect the desorption effect.

[0057] As one embodiment, the exhaust pipe 5 is connected to an air extraction device 22 via the air duct 21. The air extraction device 22 has a built-in air extraction fan, and the air extraction fan is connected to a timing sensor. The air extraction fan and the timing sensor are connected to a controller.

[0058] The working time of the adsorbent (activated carbon particles) is generally no more than 500 hours. It cannot be used for a long time and needs to be desorbed at regular intervals. When the adsorption cylinder 1 is working, it is synchronized with the gas extraction device 22. The timer sensor keeps track of the gas extraction device. When 500 hours have been reached, the adsorbent (activated carbon particles) is desorbed.

[0059] As an example, in order to facilitate the rotation of the adsorbent mesh cylinder 3 and the installation and release of adsorbent (activated carbon particles) inside the adsorbent mesh cylinder 3, the adsorbent mesh cylinder 3 is composed of an outer mesh cylinder and an inner mesh cylinder. The outer mesh cylinder and the inner mesh cylinder are fixedly connected by 6 support plates 23, thereby forming 6 chambers for installing adsorbent (activated carbon particles). Each chamber corresponds to the feed pipe 11 above. At the same time, the upper ends of the outer mesh cylinder and the inner mesh cylinder are open to facilitate the feeding of material into the feed pipe 11, and the lower ends of the outer mesh cylinder and the inner mesh cylinder are open to facilitate the discharge of adsorbent (activated carbon particles) from the discharge cylinder 9.

[0060] As an example, in order to prevent excessive airflow when exhaust gas enters and exits, an inlet baffle 24 is installed at the intake pipe 4, and a perforated baffle 25 is installed at the exhaust pipe 5. Compared with the inlet baffle 24, the perforated baffle 25 has elongated holes on the inlet baffle 24.

[0061] As an example, an exhaust gas inlet 26 and a desorption inlet 27 are provided on the intake pipe 4. The exhaust gas inlet 26 is used for exhaust gas filtration, and the desorption inlet 27 is used for desorption. An exhaust gas outlet 28 and a desorption outlet 29 are provided on the exhaust pipe 5. The exhaust gas outlet 28 is used for exhaust gas to be discharged after filtration, and the desorption outlet 29 is used for desorption.

[0062] Multiple support legs 30 are fixed to the outside of the adsorption cylinder 1 for support. A business card holder 31 is fixed to one of the support legs 30. The business card holder 31 contains the information of the business cards in the adsorption cylinder 1, such as model, size, manufacturer, and precautions.

[0063] The overall working principle of this utility model is as follows:

[0064] When installing the adsorbent (activated carbon granules), insert the feeding pipe 14 of the feeding device into the feeding pipe 11, and then add the adsorbent (activated carbon granules) from the feeding hopper 12 through the feeding device, and evenly distribute them into the adsorbent mesh cylinder 3 through the feeding pipe 14.

[0065] During exhaust gas filtration, the exhaust gas enters the exhaust gas chamber through the exhaust gas inlet 26 of the intake pipe 4 and the inlet baffle 24. Then, it is adsorbed by the adsorbent (activated carbon particles) through the inner mesh of the adsorbent mesh 3 and enters the exhaust gas chamber through the outer mesh of the adsorbent mesh 3. The gas in the exhaust gas chamber is discharged from the exhaust gas outlet 28 after passing through the perforated baffle 25 of the exhaust pipe 5.

[0066] As the adsorption cylinder 1 operates, the adsorbent mesh cylinder 3 rotates slowly to ensure that the adsorbent (activated carbon particles) inside the adsorbent mesh cylinder 3 is adsorbed evenly.

[0067] As the adsorption cylinder 1 operates, the adsorbent (activated carbon particles) sinks, and the baffle plate 8 prevents the waste gas from being discharged directly without adsorption.

[0068] When the adsorbent (activated carbon particles) needs to be desorbed, the exhaust gas inlet 26 is closed, and the mobile desorption device is connected to the desorption inlet 27 and the desorption exhaust outlet 29. Through high-temperature treatment inside the adsorption cylinder 1, the organic waste gas of the adsorbent (activated carbon particles) is rapidly desorbed.

[0069] Temperature sensor 15 is used to detect the internal temperature of adsorption cylinder 1. If the temperature is too high and the adsorbent (activated carbon particles) burns, temperature sensor 15 sends a signal to the controller. The controller controls the solenoid valve to supply water to spray pipe 16 to extinguish the fire in adsorption cylinder 1. Then the water is discharged through drain pipe 18.

[0070] When it is necessary to replace the adsorbent (activated carbon granules), open multiple discharge ports 10, and the adsorbent (activated carbon granules) can be quickly discharged through discharge block 32.

[0071] The present invention has the following technical effects.

[0072] 1. This utility model can quickly and uniformly discharge the adsorbent (activated carbon particles) through the discharge cylinder 9.

[0073] 2. This utility model can prevent the exhaust gas from being discharged directly without being adsorbed by the adsorbent (activated carbon particles) after the adsorbent (activated carbon particles) settles down by using the baffle plate 8.

[0074] 3. By rotating the adsorbent mesh cylinder 3, this utility model can ensure that the adsorbent (activated carbon particles) adsorbs the waste gas evenly, thus avoiding the problem of uneven adsorption of waste gas by the adsorbent (activated carbon particles).

[0075] 4. This utility model can quickly and evenly feed the adsorbent into the mesh cylinder through the feeding device.

[0076] 5. This utility model uses a timing sensor to time the air extraction device. Since the adsorption cylinder 1 and the air extraction device work synchronously, the working time of the adsorbent (activated carbon particles) can be recorded, which facilitates the subsequent replacement of the adsorbent (activated carbon particles).

[0077] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be obvious to those skilled in the art after reading the above content. Therefore, the scope of protection of the present invention should be defined by the appended claims.
