Description

Technical Field

[0001] The utility model relates to the technical field of waste gas recovery, in particular to a waste gas recovery device. Background Technique

[0002] The comprehensive prevention and control of air pollution refers to regarding the atmospheric environment as a whole in a specific area, unifying the planning of energy structure, industrial development, urban construction layout, etc., comprehensively applying various technical measures for pollution prevention and control, and making full use of the self-purification ability of the environment to improve air quality. Especially chemical plants, steel plants, pharmaceutical plants, coking plants, oil refineries, etc. emit waste gas with a strong smell, which seriously pollutes the environment and affects human health. Therefore, it is necessary to recover and treat the waste gas before discharging it to reduce air pollution.

[0003] In the prior art, through the settings of a purification tower, a water inlet, a spray head, a water outlet and a water circulation component, harmful gases soluble in water in the waste gas can be degraded. Spraying can increase the contact area between water flow and waste gas, and cyclic spraying can adsorb dust in the waste gas into water while saving water resources. After removing the odor of the waste gas with activated carbon, it is discharged. However, in actual use, the waste gas contains not only solid impurities soluble in water, but also more solid particles such as dust that are insoluble in water. The insoluble impurities will form hard scale after absorbing water and float or sink to the bottom. When the water circulation component pumps water, the hard scale will be pumped into the pipeline together. After long-term use, the hard scale will block the pipeline, resulting in poor use of the water circulation component. To solve the above problems, we propose a waste gas recovery device.

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0031] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0032] In the present application, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0033] Through the settings of a purification tower, a water inlet, a spray head, a water outlet, and a water circulation component, the prior art can degrade the harmful gases soluble in water in the waste gas. Spraying can increase the contact area between the water flow and the waste gas, and cyclic spraying can adsorb the dust in the waste gas into the water while saving water resources, and then discharge the waste gas after removing the odor with activated carbon.

[0034] In the related art, during actual use, the waste gas contains not only solid impurities soluble in water, but more solid particles such as dust that are insoluble in water. The impurities insoluble in water will form hard scale after absorbing water and float or sink to the bottom. When the water circulation component pumps water, the hard scale will be pumped into the pipeline together. After long-term use, the hard scale will block the pipeline, resulting in poor use of the water circulation component.

[0035] To solve the problems in the related art to a certain extent, an embodiment of the present application provides an exhaust gas recovery device. After using it for a period of time, the user opens the buckle on the cover plate 22 and the collection box 12, turns the cover plate 22 outwards to open it, exposing the internal frame 21 and the handle 213, pulls the handle 213 to pull the frame 21 outwards. The frame 21 and the collection box 12 are slidably connected through the sliding grooves of the slide rails 212. Therefore, the user can smoothly pull out the frame 21 and then clean the filter screen 211. After cleaning, align the slide rails 212 with the sliding grooves on the collection box 12 and push the frame 21 into the collection box 12 along the sliding grooves. After the frame 21 is completely pushed in, turn the cover plate 22 upwards and use the buckle to fix it on the collection box 12.

[0036] The present application will be described below with reference to the accompanying drawings and specific embodiments:

[0037] Combined with Figures 1-8 , an embodiment of the present application provides an exhaust gas recovery device, including a collection device 1; the collection device 1 includes: a collection box 12 is arranged on the top of a trolley 11, a blower 13 and a water pump 14 are arranged on the trolley 11, and the blower 13 and the water pump 14 are communicated with the collection box 12 through a pipeline 15; a liquid inlet 16 is arranged on the collection box 12, and an air outlet 17 is arranged on the collection box 12; an adjustment device 2 is arranged on the collection device 1, and the adjustment device 2 includes: a frame 21 is arranged inside the collection box 12, a filter screen 211 is arranged on the frame 21, slide rails 212 are symmetrically arranged on the outer side walls of the opposite sides of the frame 21, sliding grooves are arranged on the inner side wall of the collection box 12 and are slidably connected with the slide rails 212, a handle 213 is arranged on the frame 21, and an outlet for pulling out the frame 21 is arranged through the collection box 12; a cover plate 22 is rotatably arranged on the collection box 12, an empty groove 221 is arranged on the cover plate 22, the empty groove 221 can accommodate the handle 213, and the cover plate 22 and the collection box 12 are fixedly connected through a buckle.

[0038] The user fills the inside of the collection box 12 with water from the liquid inlet 16. There is a viewing window on the collection box 12. The user observes the perfusion water level through the viewing window and controls the perfusion water volume to the bottom of the filter screen 211. Then, the trolley 11 is pushed to the main locations where waste gas is concentrated, such as chemical plants, steel plants, pharmaceutical factories, coking plants, and oil refineries. The switches of the fan 13 and the water pump 14 are turned on. The fan 13 absorbs the waste gas carrying a large amount of soot and powder particles inside the area, enters the collection box 12 from the top of the collection box 12 through the pipeline 15. At the same time, the water pump 14 pumps water from the collection box 12 into the collection box 12 through the pipeline 15 and sprays it out from the atomizing nozzle. After the waste gas and water in the collection box 12 are mixed, the solid impurities in the waste gas, such as powder and soot, are mixed with water to form hard scale, which falls downward under the action of gravity and enters the filter screen 211. The excess water passes through the filter screen 211 and falls on the bottom of the collection box 12, which can realize the recycling of water and save water resources. After using for a period of time, the user opens the buckle on the cover plate 22 and the collection box 12, turns the cover plate 22 outwards to open it, exposing the internal frame 21 and the handle 213. The handle 213 is pulled to pull the frame 21 outwards. The frame 21 and the collection box 12 are slidably connected through the slide rail 212 and the chute. Therefore, the user can smoothly pull out the frame 21 and then clean the filter screen 211. After cleaning, align the slide rail 212 with the chute on the collection box 12 and push the frame 21 into the collection box 12 along the chute. After the frame 21 is completely pushed in, turn the cover plate 22 upwards and fix it on the collection box 12 with a buckle.

[0039] Specifically, the water pump 14 provides pressure for the atomizing nozzle to spray water. There are multiple water spraying holes on the atomizing nozzle. Therefore, the water flow is divided into small water droplets and sprayed out to form a mist surface. On the one hand, it saves water resources, and on the other hand, it makes the contact area between water and waste gas larger, and mixes more evenly with the solid impurities in the waste gas to improve the separation efficiency.

[0040] In some embodiments, hook bodies 23 are symmetrically arranged on the outer side wall of the cover plate 22. A fixed block 24 is arranged on the outer side wall of the collection box 12. A wrench 242 is rotatably arranged on the fixed block 24 through a first rotating shaft 241. A housing 25 is rotatably arranged on the wrench 242 through a second rotating shaft 243. Chutes 251 are symmetrically arranged on the housing 25. Sliders 252 are arranged on the chutes 251. A push plate 26 is arranged in the middle of the slider 252. A rod body 261 is arranged on the push plate 26. The rod body 261 penetrates through the housing 25 and is provided with a lock head 262. The lock head 262 is clamped with the hook body 23.

[0041] The user puts the lock 262 on the hook body 23, and then pulls down the wrench 242. During the pulling process, the wrench 242 rotates with the first rotating shaft 241 as the fulcrum. The second rotating shaft 243 is arranged at the rear half of the housing 25. Therefore, the housing 25 moves forward under the pushing action of the wrench 242. The lock 262 and the hook body 23 are in a clamped state. At the same time, the lock 262 is fixedly connected to the rod body 261 and the push plate 26. The rod body 261 penetrates through the housing 25, and the push plate 26 is slidably connected to the housing 25. Therefore, the push plate 26 will move on the housing 25 to provide space for the movement of the lock 262. After the push plate 26 moves to a certain extent, it will drive the lock 262 to move downward through the rod body 261 and sleeve it on the hook body 23 to complete the fixation of the cover plate 22. The same operation is performed at both ends of the cover plate 22 to complete the fixation of the lock 262 and the hook body 23. Lifting the wrench 242 upward can control the lock 262 to disengage from the hook body 23, thus releasing the clamped fixation of the hook body 23 and the lock 262. In this way, the cover plate 22 and the collection box 12 are in closer contact and the sealing effect is better.

[0042] Specifically, pressing the wrench 242 to lock is designed according to the relevant lever principle. The basic principle of the lever locking mechanism is based on the mechanical principle of the lever, that is, "the moment is equal to the resistance moment". By changing the magnitude and position of the force acting on the lever, different moments can be generated, thereby realizing the locking or unlocking operation.

[0043] In some embodiments, the tail of the wrench 242 is set to be curved. The curved tail of the wrench 242 provides a force application point for the user and is convenient for the user to control the magnitude of the applied force.

[0044] In some embodiments, a limiting block 253 is arranged on the slider 252. Arranging the limiting block 253 on the slider 252 can further limit the slider 252 to prevent the slider 252 from being worn and affecting the smoothness of sliding.

[0045] In some embodiments, a spring 263 is sleeved outside the rod body 261. Under the elastic force of the spring 263, the lock 262 receives a stronger pulling force when clamped with the hook body 23, improving the stability when the lock 262 and the hook body 23 are clamped.

[0046] In some embodiments, the hook body 23 is L-shaped. The L-shaped hook body 23 limits the lock 262 during clamping to prevent the lock 262 from derailing and improving the stability.

[0047] In some embodiments, a housing 27 is fixedly arranged on the air outlet 17 through a flange interface 271 and bolts, and an activated carbon net 272 is arranged inside the housing 27. A pipeline with a flange interface 271 is arranged on the air outlet 17. The user can use bolts to fixedly connect this pipeline and the housing 27 with the flange interface 271. After the waste gas is treated, it is discharged from the air outlet 17 into the housing 27, and the peculiar smell is absorbed by the activated carbon net 272. The adsorption principle of activated carbon includes physical adsorption and chemical adsorption. Physical adsorption provides a large surface area and pore structure, enabling activated carbon to effectively adsorb organic molecule; while chemical adsorption further enhances the adsorption capacity for specific organic matters through chemical bond action. The combination of these two adsorption methods makes activated carbon show efficient and stable effects when treating various pollutants, removing the pungent smell in the gas and preventing the peculiar smell from harming the health of users.

[0048] In some embodiments, a fixing column 273 is arranged on the trolley 11, and the fixing column 273 is fixedly connected to the air outlet 17. Arranging the fixing column 273 to support the air outlet 17 can ensure the stability of the air outlet 17 and improve the integration and structural stability of the whole device.
