Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, and in particular to an activated carbon treatment device for odor generated by the evaporation of landfill leachate. Background Technology

[0002] Landfill leachate is a high-concentration organic wastewater produced during the landfilling and disposal of waste due to biochemical changes such as compaction and fermentation, as well as external factors such as precipitation. It contains a large amount of pollutants such as organic matter, ammonia nitrogen, and heavy metals. With the operation of landfills or waste treatment facilities, the amount of leachate generated is quite considerable. If this leachate is not properly treated, it will cause serious pollution to soil, surface water, and groundwater, affecting the surrounding ecological environment and the health of residents.

[0003] Most current activated carbon adsorption treatment equipment for waste gas only sets up a single layer of activated carbon adsorption mesh for adsorption, which cannot effectively treat waste gas. Some waste gas treatment devices with multiple activated carbon adsorption meshes will also be too large, making them inconvenient for actual waste gas treatment. After long-term use, a lot of organic matter will adhere to the activated carbon, making it difficult to disassemble and clean, which will also affect the waste gas purification function.

[0004] The existing patent (publication number: CN215311282U) discloses an activated carbon adsorption device for high-efficiency waste gas treatment. This device, through the configuration of an external waste gas pipe, a suction machine, an inlet pipe, a support rod, a first hemisphere, a guide plate, an arc-shaped groove, an activated carbon plate, a second hemisphere, and an exhaust pipe, achieves the following: When waste gas is drawn in at high power by the suction machine, it enters the sealed first and second hemispheres and circulates through the guide plate. During this circulation, the waste gas is continuously purified by the activated carbon plate. After a certain period, the suction machine is adjusted to low power or turned off. At this point, the purified gas, with its high buoyancy, can be discharged through the exhaust pipe, thus achieving the function of waste gas circulation and purification. The device also incorporates an arc-shaped groove in the first and second hemispheres, a fixing block, a screw, a semi-circular groove, and a ring. The two hemispheres are hinged, which facilitates opening and cleaning while maintaining the waste gas purification effect, extending the equipment's lifespan, and saving on replacement costs.

[0005] To address the aforementioned issues, existing patents offer solutions. Existing activated carbon treatment equipment for odor generated by leachate evaporation primarily uses activated carbon inside the adsorption device to adsorb and filter the odor. However, it is not convenient to adjust the temperature and pressure inside the adsorption device, resulting in a decrease in the adsorption rate and capacity of the activated carbon when treating odors of different concentrations. Moreover, odors usually contain complex macromolecular organic matter, and the activated carbon is prone to clogging its pores by adsorbing impurities in the odor, leading to a decrease in the adsorption efficiency of the activated carbon.

[0006] Therefore, an activated carbon treatment device for odor generated by the evaporation of landfill leachate is proposed. Utility Model Content

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This application can regulate the temperature inside the adsorption box through the adsorption component. The appropriate temperature helps to improve the adsorption rate of activated carbon and accelerate the diffusion speed of odor molecules in the pores, thereby enhancing the adsorption effect. At the same time, it can also reduce the pressure inside the adsorption frame, making it easier for odor molecules to be adsorbed onto the activated carbon, increasing the adsorption capacity of the activated carbon. Moreover, odor molecules that are not completely adsorbed can be passed through the activated carbon adsorption plate again to further improve the adsorption efficiency, so as to ensure that the discharged gas meets a higher purification standard.

[0021] 2. This application enables the odor to undergo preliminary treatment before entering the adsorption box through the pretreatment component, thereby removing some pollutants and changing the properties of the pollutants. This makes the subsequent activated carbon adsorption process more efficient and stable, preventing the activated carbon from being clogged due to the presence of complex macromolecular organic matter in the odor. At the same time, it improves the adsorption box's ability to treat odor generated by the evaporation of landfill leachate, reduces the impact of odor emissions on the environment, and ensures the air quality around the landfill treatment facility.

Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-6 The present invention provides the following technical solution:

[0031] An activated carbon treatment device for odor generated by the evaporation of landfill leachate includes an adsorption box 1, an adsorption component 5 is installed inside the adsorption box 1, a connecting pipe 2 is connected to the left side of the adsorption box 1, and a pretreatment component 6 is installed on the left side of the connecting pipe 2.

[0032] The adsorption assembly 5 includes an adsorption frame 501 fixedly connected inside the adsorption box 1. A multi-layer activated carbon adsorption plate 502 is slidably connected inside the adsorption frame 501. A heating wire 503 is installed inside the adsorption frame 501. A temperature controller 504 is bolted to the rear side of the adsorption box 1. The temperature controller 504 is electrically connected to the heating wire 503. A vacuum adsorption plate 505 is bolted to the right side of the adsorption frame 501. A vacuum pipe 506 is connected to the rear side of the vacuum adsorption plate 505. A vacuum pump 507 is bolted to the rear side of the adsorption box 1. The vacuum pump 507 is bolted to the vacuum pipe 506. A circulating fan 508 is bolted to the rear side of the adsorption box 1. A circulation pipe 509 is bolted to the outside of the circulating fan 508. The circulation pipe 509 is connected to both sides of the adsorption box 1.

[0033] In this embodiment: the pretreated odor gas is adsorbed and filtered by the multi-layer activated carbon adsorption plate 502. Simultaneously, the temperature controller 504 is activated, controlling the heating temperature of the heating wire 503. The heating wire 503, bolted inside the adsorption frame 501, maintains a suitable temperature for the activated carbon during adsorption, thus improving adsorption efficiency. Next, the vacuum pump 507 is activated, transferring its suction force to the vacuum adsorption plate 505 through the vacuum pipe 506 to reduce the pressure within the adsorption frame 501, thereby altering the adsorption balance and increasing the adsorption capacity and rate of the activated carbon for the odor gas. Simultaneously, the circulating fan 508 is activated, and then the odor gas is filtered through the circulation pipe 509. Partially treated gas circulates within adsorption box 1, further improving odor treatment efficiency and enabling activated carbon to more fully adsorb pollutants in the odor. When the activated carbon adsorption reaches or is close to saturation, the heating wire 503 is heated by the temperature controller 504 to heat the multi-layer activated carbon adsorption plate 502, causing the organic matter adsorbed on the activated carbon to volatilize and desorb. At the same time, the vacuum pump 507 is activated to create negative pressure inside the adsorption frame 501 to promote the desorption of organic matter and regenerate the activated carbon inside the multi-layer activated carbon adsorption plate 502. The regenerated activated carbon can continue to be used for odor treatment, extending the service life of the activated carbon and reducing operating costs.

[0034] Specifically, such as Figure 3 , Figure 5 As shown, the pretreatment assembly 6 includes a pretreatment box 601 bolted to the left side of the connecting pipe 2. An ultrasonic oscillation generator 602 is bolted to the top of the pretreatment box 601, and an ultrasonic transducer 603 is bolted to the output end of the ultrasonic oscillation generator 602.

[0035] Specifically, such as Figure 3 As shown, a high-voltage electrostatic field generator 604 is bolted to the inside of the pretreatment box 601, and an electrode plate 605 is bolted to the inside of the high-voltage electrostatic field generator 604. The electrode plate 605 is located on the right side of the ultrasonic transducer 603.

[0036] Specifically, such as Figure 3 As shown, a lamp holder 606 is bolted inside the pretreatment box 601, an ultraviolet lamp tube 607 is bolted inside the lamp holder 606, a reflector 608 is bolted to the outside of the lamp holder 606, the ultraviolet lamp tube 607 is located on the right side of the electrode plate 605, and a fiber filter plate 609 is bolted to the right side inside the pretreatment box 601.

[0037] In this embodiment: when the odorous gas enters the pretreatment chamber 601, it first undergoes ultrasonic waves generated by the ultrasonic oscillator 602. The ultrasonic oscillator 602 then generates a high-frequency electrical signal, which is converted into mechanical vibration by the ultrasonic transducer 603 connected to the output end, thereby generating ultrasonic waves. These ultrasonic waves cause the odorous gas molecules to vibrate violently, prompting some large organic molecules to decompose into smaller molecules, facilitating subsequent processing. The odorous gas, after ultrasonic treatment, then enters the electric field range generated by the high-voltage electrostatic field generator 604. The high-voltage electrostatic field generator 604 generates a high-voltage electrostatic field, forming a strong electric field between the inner electrode plates 605. This causes the charged particles in the odorous gas to move directionally and be adsorbed under the influence of the electric field force, thus removing the odorous gas. Some of the charged pollutant particles are decomposed by electrostatic forces, which also help to break down some polar molecules. The odor then passes through the irradiation area of ​​the ultraviolet lamp 607, and its reflector 608 reflects the ultraviolet light emitted by the ultraviolet lamp 607 back into the odor to enhance the utilization efficiency of the ultraviolet light. The ultraviolet light inactivates the microorganisms in the odor, preventing them from growing and multiplying in subsequent treatments. Finally, the odor passes through the fiber filter plate 609 bolted to the right side inside the pre-treatment filter box 601. The fiber filter plate 609 is made of multiple layers of fiber materials with different pore sizes, which can intercept the small particles and incompletely decomposed large organic molecules that remain after the previous treatment, preventing them from entering the activated carbon adsorption unit and causing blockage, thus ensuring the adsorption efficiency and service life of the activated carbon.

[0038] Specifically, such as Figure 4 As shown, a connecting plate 3 is bolted to the front side of the multi-layer activated carbon adsorption plate 502, and a pull rod 4 is fixedly connected to the front side of the connecting plate 3.

[0039] Specifically, such as Figure 4 As shown, a limiting member 7 is bolted to the front side of the adsorption box 1. A limiting rod 8 is rotatably connected to the inner side of the limiting member 7. A rubber pad 9 is glued to the inner side of the limiting rod 8. The rubber pad 9 is located on the front side of the connecting plate 3. A movable handle 21 is fixedly connected to the inner side of the limiting rod 8. A fixing member 10 is bolted to the right side of the limiting rod 8. The fixing member 10 is threadedly connected to the adsorption box 1. A limiting block 11 is fixedly connected to the inner side of the fixing member 10. The limiting block 11 is snapped into the adsorption box 1.

[0040] In this embodiment: By setting the connecting plate 3 and the pull rod 4, when it is necessary to install or replace the multi-layer activated carbon adsorption plate 502, the user can hold the pull rod 4 on the connecting plate 3 bolted to the front of the multi-layer activated carbon adsorption plate 502 and slide the multi-layer activated carbon adsorption plate 502 within the adsorption frame 501 to facilitate subsequent replacement. By setting the limiting member 7, the limiting rod 8, the rubber pad 9, the moving handle 21, the fixing member 10, and the limiting block 11, after the multi-layer activated carbon adsorption plate 502 is installed, the limiting rod 8 is rotated to make the rubber pad 9 adhered to its inner side tightly connected to the front side of the connecting plate 3. The rubber pad 9 acts as a buffer and increases friction to prevent the multi-layer activated carbon adsorption plate 502 from shifting due to vibration or other reasons during equipment operation. Then, the fixing part 10 is threadedly connected to the adsorption box 1, so that the limiting block 11 on the inner side of the fixing part 10 is engaged with the adsorption box 1 to fix the multi-layer activated carbon adsorption plate 502. When it is necessary to disassemble the multi-layer activated carbon adsorption plate 502, the fixing part 10 is rotated in the opposite direction to disengage it from the adsorption box 1. Then, the limiting rod 8 is rotated by moving the moving handle 21 to move it away from the front side of the connecting plate 3, thereby releasing the fixation of the multi-layer activated carbon adsorption plate 502.

[0041] Specifically, such as Figure 5 As shown, a connecting flange 12 is bolted to the left side of the pretreatment box 601, an air inlet pipe 13 is bolted to the left side of the connecting flange 12, and a top cover 14 is threaded to the left side of the air inlet pipe 13.

[0042] Specifically, such as Figure 6 As shown, an exhaust pipe 15 is connected to the right side of the adsorption box 1, and a control valve 16 is provided on the outside of the exhaust pipe 15.

[0043] In this embodiment: By setting up a connecting flange 12, an air inlet pipe 13, and a top cover 14, when installing the air inlet pipe 13, the connecting flange 12 is used to fix the air inlet pipe 13 to the pretreatment box 601 with bolts and other connecting parts to ensure the sealing of the connection. At the same time, the top cover 14 on the left side of the air inlet pipe 13 can seal the air inlet pipe 13 when the equipment is not in use to prevent foreign objects from entering. By setting up an air outlet pipe 15 and a control valve 16, the air outlet pipe 15 is used to discharge the gas after activated carbon adsorption treatment, and the control valve 16 can adjust the valve opening according to actual needs to control the gas discharge flow rate to ensure the stable operation of the system.

[0044] Specifically, such as Figure 1 As shown, a pressure regulating valve 17 is provided on the outside of the connecting pipe 2, and sealing sleeves 18 are fitted on both sides of the connecting pipe 2.

[0045] Specifically, such as Figure 1As shown, a support leg 19 is fixedly connected to the bottom of the adsorption box 1, and an anti-slip pad 20 is glued to the bottom of the support leg 19. The anti-slip pad 20 is made of rubber.

[0046] In this embodiment: by setting a pressure regulating valve 17 and a sealing sleeve 18, the pressure regulating valve 17 can accurately control the gas pressure to ensure that the odor is in a suitable pressure state when it enters the adsorption box 1. The sealing sleeve 18 can effectively prevent the odor from leaking at the connection point between the connecting pipe 2 and the adsorption box 1 and the pretreatment box 601, so as to avoid the odor leakage from polluting the surrounding environment. By setting a support leg 19 and an anti-slip pad 20, the anti-slip pad 20 increases the friction between the ground and the support leg 19, effectively preventing the adsorption box 1 from sliding or shifting, so as to ensure the safe operation of the equipment.

[0047] Working Principle: In the process of using activated carbon to treat odorous gases generated by leachate evaporation, the odorous gases first enter the pretreatment tank 601 through the inlet pipe 13. The connecting flange 12 ensures the airtightness of the connection between the inlet pipe 13 and the pretreatment tank 601. After the odorous gases enter the pretreatment tank 601, they are first subjected to ultrasonic waves generated by the ultrasonic oscillator 602. Then, the ultrasonic oscillator 602 generates a high-frequency electrical signal, which is converted into mechanical vibration by the ultrasonic transducer 603 connected to the output end, thereby generating ultrasonic waves. The ultrasonic waves cause the odorous gas molecules to vibrate violently, causing some of the large organic molecules to decompose into smaller molecules, which are easier to process later. Then, the odorous gases after ultrasonic treatment enter the high-voltage electrostatic field generator. The electric field range generated by 604, followed by the high-voltage electrostatic field generator 604 generating a high-voltage electrostatic field, forms a strong electric field between the inner electrode plates 605, causing the charged particles in the odor to move directionally and be adsorbed under the action of the electric field force, removing some of the charged pollutant particles. At the same time, the electrostatic effect also helps to decompose some polar molecules. Then, the odor passes through the irradiation area of ​​the ultraviolet lamp tube 607, and its reflector 608 reflects the ultraviolet rays emitted by the ultraviolet lamp tube 607 back into the odor, thereby enhancing the utilization efficiency of ultraviolet rays. The ultraviolet rays inactivate the microorganisms in the odor, preventing the microorganisms from growing and multiplying in subsequent treatment processes. Finally, the odor passes through the fiber filter plate 609 attached to the right side inside the filter pretreatment box 601, and the fiber filter plate 609 adopts... Made of multi-layered fiber materials with different pore sizes, it can intercept residual microparticles and incompletely decomposed macromolecular organic matter after pretreatment, preventing them from entering the activated carbon adsorption unit and causing blockage, thus ensuring the adsorption efficiency and service life of the activated carbon. The pretreated odorous gas then enters the adsorption chamber 1 through connecting pipe 2. The multi-layered activated carbon adsorption plate 502 then adsorbs and filters the pretreated odorous gas. Simultaneously, the temperature controller 504 is activated, controlling the heating temperature of the heating wire 503. The heating wire 503, bolted inside the adsorption frame 501, maintains a suitable temperature for the activated carbon during adsorption, improving adsorption efficiency. Then, the vacuum pump 507 is activated, transmitting suction through the vacuum pipe 506. The gas is directed to the vacuum adsorption plate 505 to reduce the pressure within the adsorption frame 501, thereby altering the adsorption equilibrium and increasing the adsorption capacity and rate of the activated carbon for odors. Simultaneously, the circulating fan 508 is activated, and then a portion of the treated gas circulates within the adsorption chamber 1 through the circulation pipe 509, further improving the odor treatment efficiency and allowing the activated carbon to more fully adsorb pollutants from the odor. The gas treated by activated carbon adsorption is then discharged from the outlet pipe 15 on the right side of the adsorption chamber 1. The control valve 16 controls the outlet flow rate and the start / stop of the equipment, ensuring that the discharged gas meets environmental emission standards and reduces pollution to the surrounding environment. When the activated carbon adsorption reaches or is close to saturation, the heating wire 503 is heated by the temperature controller 504.The multi-layer activated carbon adsorption plate 502 is heated to cause the organic matter adsorbed on the activated carbon to volatilize and desorb. Simultaneously, the vacuum pump 507 is activated to create negative pressure inside the adsorption frame 501, further promoting the desorption of organic matter and regenerating the activated carbon inside the multi-layer activated carbon adsorption plate 502. The regenerated activated carbon can then be reused for odor treatment, extending its service life and reducing operating costs.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
