Description

Technical Field

[0001] This utility model relates to the field of deodorization biological filter technology, specifically a vertical multi-stage deodorization biological filter. Background Technology

[0002] In today's society, with the increasing awareness of environmental protection and the growing demands for the quality of living environment, effectively treating various types of odor pollution has become an important issue that urgently needs to be addressed. From the perspective of industrial production, chemical and pharmaceutical plants generate a large amount of complex odors with varying concentrations. If these odors are discharged directly without proper treatment, they will not only cause serious pollution to the surrounding atmospheric environment but also greatly affect the comfort of residents' lives. From the perspective of urban construction, the odors emitted by facilities such as urban sewage treatment plants also have a negative impact on the city's image and the quality of life of residents. Biological deodorization, as a green, environmentally friendly, and efficient deodorization method, has received widespread attention. However, traditional biological deodorization devices have gradually revealed some limitations in dealing with increasingly complex odor components and higher deodorization requirements. Therefore, a vertical multi-stage deodorization biological filter has emerged.

[0003] However, existing vertical multi-stage deodorization biological filters have the following problems: First, when the adsorbent material in the filter reaches saturation or its performance deteriorates, operators need to spend a lot of time disassembling parts and cleaning materials, which not only significantly reduces maintenance efficiency but also prolongs the filter downtime. Failure to replace the adsorbent material in time will reduce the deodorization efficiency of the filter, weaken its ability to treat complex odors, and ultimately affect the overall deodorization effect and environmental quality assurance capabilities. Second, the spraying process wastes water resources, significantly increases operating costs, increases equipment maintenance pressure, and makes it difficult to achieve efficient use of water resources, which contradicts the circular economy concept advocated in the current environmental protection field.

[0004] To address these issues, we have developed a vertical multi-stage deodorizing biological filter. Utility Model Content

[0005] The purpose of this invention is to provide a vertical multi-stage deodorizing biological filter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical multi-stage deodorizing biological filter, including a base frame, a quick-release adsorption mechanism on one side of the base frame, and a circulating spray mechanism installed on the top surface of the base frame.

[0007] Preferably, the quick-release adsorption mechanism includes an adsorption box fixedly connected to one side of the base frame, an air inlet on one side of the adsorption box, three layers of tracks fixedly connected to both sides inside the adsorption box, mesh plates inserted into the tracks, activated carbon placed on the top surface of the mesh plates for preliminary filtration of the gas, and a delivery pipe on the top surface of the adsorption box through which the filtered gas enters the next stage of filtration.

[0008] Preferably, the circulating spraying mechanism includes a spraying box fixedly connected to the top surface of the base frame, a water tank is provided on one side of the spraying box, a maifan stone filter plate is provided at the connection between the spraying box and the water tank to absorb odors in the water, and a water pressure pump is fixedly connected to the top surface of the water tank.

[0009] Preferably, the water pressure pump pressurizes the liquid in the water tank and then flows it through a circulation pipe fixedly connected to the top surface of the water tank to two sets of branch pipes opened thereon. The nozzles opened on the outer edge of the branch pipes spray the liquid out to circulate and spray the gas for deodorization.

[0010] Preferably, two layers of grid plates are fixedly connected to the inner edge of the spray box. Several biological fillers are placed on the top surface of the grid plates to adsorb and deodorize and prolong the time the gas stays in the spray box. A demisting plate is fixedly connected to the inner edge of the spray box to reduce the water vapor content in the gas after spraying. An air outlet is opened on the top surface of the spray box to discharge the deodorized gas.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model constitutes a quick-release adsorption mechanism by adding adsorption boxes and activated carbon. The activated carbon laid on the top surface of the mesh plate utilizes its porous structure and adsorption characteristics to physically adsorb odors in the gas, achieving preliminary filtration and purification. When the activated carbon is saturated, the operator can directly and quickly pull out the mesh plate along the track to replace it, improving equipment maintenance efficiency and deodorization stability. The adsorption material can be replaced in a short time through quick insertion and removal, greatly shortening the filter downtime. 2. This utility model constructs a circulating spraying mechanism by incorporating biological fillers and demister plates. A water pump pressurizes the liquid in the water tank, and the pressurized liquid is diverted to two sets of branch pipes through the circulation pipe on the top of the water tank. The nozzles on the outer edge of the branch pipes atomize and spray the liquid. The sprayed liquid flows back to the water tank, is purified by the maifan stone filter plate, and is pressurized and circulated again, achieving continuous spraying deodorization and water resource reuse. Biological fillers are placed on the two layers of grid plates in the spraying box. The fillers degrade odor components, and the water vapor generated by spraying is blocked and separated by the demister plate. Finally, the deodorized and dry gas is discharged from the top air outlet, which can realize the efficient recycling of water resources, reduce operating costs and water consumption, and enhance the economic efficiency of the equipment while strengthening its environmental friendliness and sustainability.

[0021] 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.

[0022] Please see Figure 1-5 One embodiment of this utility model is a vertical multi-stage deodorizing biological filter, which includes a base frame 1, a quick-release adsorption mechanism 2 on one side of the base frame 1, and a circulating spray mechanism 3 installed on the top surface of the base frame 1.

[0023] Furthermore, the quick-release adsorption mechanism 2 includes an adsorption box 201 fixedly connected to one side of the base frame 1. An air inlet 202 is provided on one side of the adsorption box 201. Three layers of tracks 203 are fixedly connected to both sides inside the adsorption box 201. A mesh plate 204 is inserted into the track 203. Activated carbon 205 is placed on the top surface of the mesh plate 204 to perform preliminary filtration of the gas. A conveying pipe 206 is provided on the top surface of the adsorption box 201, through which the filtered gas enters the next stage of filtration. Gas with odors enters from the air inlet 202 on one side of the adsorption box 201. The activated carbon 205 laid on the top surface of the mesh plate 204 utilizes its porous structure and adsorption characteristics to physically adsorb odor molecules, impurities, etc. in the gas, achieving preliminary filtration and purification. The filtered gas is discharged through the conveying pipe 206 on the top surface of the adsorption box 201 and enters the next stage of filtration. When the activated carbon 205 is saturated, the operator can directly and quickly pull out the mesh plate 204 along the track 203 for convenient replacement.

[0024] Furthermore, the circulating spraying mechanism 3 includes a spraying box 301 fixedly connected to the top surface of the base frame 1. A water tank 302 is provided on one side of the spraying box 301. A maifan stone filter plate 303 is provided at the connection between the spraying box 301 and the water tank 302 to absorb odors in the water. A water pressure pump 304 is fixedly connected to the top surface of the water tank 302. The water in the water tank 302 flows into the spraying box 301 for spraying under the drive of the water pressure pump 304. The maifan stone filter plate 303 located at the connection between the spraying box 301 and the water tank 302 plays an adsorption role, using its porous structure and surface characteristics to remove odors. The purified water is then pumped out again by the water pressure pump 304 for recycling.

[0025] Furthermore, the water pressure pump 304 pressurizes the liquid in the water tank 302 and then flows it through the circulation pipe 305 fixedly connected to the top surface of the water tank 302 to the two sets of branch pipes 306. The nozzles 307 on the outer edge of the branch pipes 306 spray the liquid to circulate and deodorize the gas. The water pressure pump 304 pressurizes the liquid in the water tank 302, and the pressurized liquid is diverted through the circulation pipe 305 on the top surface of the water tank 302 to the two sets of branch pipes 306. The nozzles 307 on the outer edge of the branch pipes 306 atomize the liquid and spray it out to fully contact the gas to absorb odors. The sprayed liquid flows back to the water tank 302, is purified by the maifan stone filter plate 303, and is pressurized and circulated again to achieve continuous spray deodorization and water resource reuse.

[0026] Furthermore, two layers of grid plates 308 are fixedly connected to the inner edge of the spray box 301. Several biological fillers 309 are placed on the top surface of the grid plates 308 to adsorb and deodorize, and to prolong the time the gas stays in the spray box 301. A demister plate 310 is fixedly connected to the inner edge of the spray box 301 to reduce the water vapor content in the gas after spraying. An air outlet 311 is opened on the top surface of the spray box 301, through which the deodorized gas is discharged. Biological fillers 309 are placed on the two layers of grid plates 308 in the spray box 301. When the gas enters the spray box 301, it is sprayed by the liquid sprayed by the nozzle 307. The liquid adsorbs the odor substances in the gas. On the other hand, when the gas passes through the biological fillers 309, the microorganisms on the surface of the fillers degrade the odor components through metabolism. At the same time, the structure of the grid plates 308 and the fillers prolongs the residence time of the gas in the box, improving the treatment efficiency. The water vapor generated by spraying is blocked and separated by the demister plate 310. Finally, the deodorized dry gas is discharged from the air outlet 311 on the top surface.

[0027] Working principle: Odor-laden gas enters through the air inlet 202 on one side of the adsorption box 201. Activated carbon 205, laid on the top surface of the mesh plate 204, utilizes its porous structure and adsorption properties to physically adsorb odor molecules and impurities in the gas, achieving preliminary filtration and purification. The filtered gas is discharged through the conveying pipe 206 on the top surface of the adsorption box 201 and enters the spray box 301. When the activated carbon 205 is saturated, the operator can directly and quickly pull out the mesh plate 204 along the track 203 for convenient replacement. The water pump 304 pressurizes the liquid in the water tank 302. The pressurized liquid is then diverted through the circulation pipe 305 on the top surface of the water tank 302 to two sets of branch pipes 306. The nozzles 307 on the outer edge of the branch pipes 306 atomize the liquid and spray it out, fully mixing with the gas. The liquid is sprayed to absorb odors and then returned to the water tank 302. After being purified by the maifan stone filter plate 303, it is pressurized and circulated again to achieve continuous spray deodorization and water resource reuse. Biological packing material 309 is placed on the two layers of grid plates 308 in the spray box 301. When the gas enters the spray box 301, it is sprayed by the liquid sprayed by the nozzle 307. The liquid absorbs the odor substances in the gas. On the other hand, when the gas passes through the biological packing material 309, the microorganisms on the surface of the packing material degrade the odor components through metabolism. At the same time, the structure of the grid plate 308 and the packing material prolongs the residence time of the gas in the box and improves the treatment efficiency. The water vapor generated by the spraying is blocked and separated by the demister plate 310. Finally, the deodorized and dry gas is discharged from the top air outlet 311.

[0028] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
