Description

Technical Field

[0001] This utility model relates to the field of deodorization devices, specifically a filter bed deodorization device. Background Technology

[0002] A biofilter is a biological treatment technology that uses microorganisms to degrade pollutants in waste gas or wastewater. Its core is to provide a carrier for microorganisms through a packing layer to form a biofilm, thereby achieving the adsorption, absorption and metabolism of pollutants.

[0003] In existing technologies, biofilters are generally placed directly in the environment. However, during use and observation, it has been found that when the ambient temperature is low, the activity of microorganisms in the biofilter decreases, which in turn affects its ability to deodorize odors.

[0004] Therefore, a filter bed deodorization device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The filter deodorization device of this utility model includes a box body, one side of which is connected to a second tank body; a heating pipe is fixedly connected to the inner wall of the second tank body, and the heating pipe has a spiral structure; a pretreatment mechanism is connected to one side of the second tank body, and the outer wall of the pretreatment mechanism is provided with an air inlet; a pair of first grids are fixedly connected to the inner wall of the box body, and a porous packing biological filter bed is provided between the pair of first grids; a spray assembly is provided at the top of the first grids, and multiple nozzles are provided at the bottom of the spray assembly; an exhaust pipe is connected to the top of the box body; by setting the heating pipe, the odor can be preheated to appropriately heat the microorganisms in the porous packing biological filter bed, so as to ensure that the microorganisms are in a suitable working environment and that they can stably deodorize the odor.

[0007] Preferably, a column is fixedly connected to the bottom of the inner wall of the second tank; a plurality of first guide plates are fixedly connected to the outer wall of the column, and the surface of the first guide plates is an arc-shaped structure; by setting the first guide plates, the flow trajectory of the odor can be changed when the odor flows in the second tank, thereby increasing the heating effect of the heating tube on the odor.

[0008] Preferably, the pretreatment mechanism includes a first tank; the first tank and a second tank are connected by a pipeline; a fixing plate is fixedly connected to the inner wall of the first tank; a main pipe is fixedly connected to the top of the fixing plate; a water inlet pipe is connected to one side of the main pipe; a turbine is installed on the inner wall of the main pipe; a water distribution plate is fixedly connected to the bottom of the turbine; the water distribution plate and the main pipe are rotatably connected; multiple inclined branch pipes are connected to the bottom of the water distribution plate; the bottom of the branch pipes is perforated; a pair of packing layers are fixedly connected to the inner wall of the first tank; a second grid is provided between the pair of packing layers. After the odor enters the first tank through the air inlet, the water inlet pipe connects to the water pump, allowing clean water to enter the water distribution plate through the main pipe. During this process, the turbine rotates under the impact of the water flow. At this time, the turbine will rotate the water distribution plate and the branch pipe, causing the water to spray out in a rotating state along with the branch pipe. Since the branch pipe is set at an angle, the spray range of the water flow can be further expanded, thereby increasing the contact area between the water flow and the odor. At the same time, the gas-liquid contact area in the second grid can be expanded to assist in the removal of impurities from the gas. The second grid can be filled with plastic.

[0010] Preferably, a plurality of second guide plates are fixed to the inner wall of the first tank; the second guide plates are staggered and inclined; by setting the second guide plates, the odor entering from the air inlet will flow upward in a serpentine trajectory under the guidance and obstruction of the second guide plates, so as to slow down the odor and increase the contact time between the odor and the water in the first tank.

[0011] Preferably, an insulation board is fixed to the outer wall of the box; by setting the insulation board, the insulation board will keep the porous packing biological filter bed inside the box warm, so as to reduce the heat exchange between it and the low temperature environment outside.

[0022] 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1 to 5As shown in the embodiment of this utility model, a filter deodorization device includes a housing 13, with a second tank 12 connected to one side of the housing 13; a heating pipe 18 is fixedly connected to the inner wall of the second tank 12, and the heating pipe 18 has a spiral structure; a pretreatment mechanism is connected to one side of the second tank 12, and an air inlet is provided on the outer wall of the pretreatment mechanism; a pair of first grids 14 are fixedly connected to the inner wall of the housing 13, and a porous packing biological filter bed 15 is provided between the pair of first grids 14; a spray assembly 16 is provided at the top of the first grids 14, and multiple nozzles are provided at the bottom of the spray assembly 16; an exhaust pipe 17 is connected to the top of the housing 13; during operation, odorous gas can be introduced into the pretreatment mechanism through the air inlet by a centrifugal fan, and the pretreatment mechanism will spray and humidify the odorous gas to remove particulate matter and some water-soluble pollutants in the odorous gas. The pretreated odorous gas can enter the second tank 12 through a pipe, and at this time, the heating pipe 18 in the second tank 12 can form a thermal circulation system through a circulation pump, a medium supply device, a heating assembly, etc., so that the heating pipe 18... The flowing heating medium heats the odorous gas through heat conduction. The heated odorous gas enters the bottom of the chamber 13 through a pipe and passes through the first grid 14 and the porous packing biofilter 15. At the same time, the spray assembly 16 can be connected to an external water pump to spray through the nozzles. At this time, the pollutants in the odorous gas are transferred from the gas phase to the surface of the biofilm. The malodorous components that enter the biofilm are removed by the absorption and decomposition of microorganisms in the biofilter. The odorous gas can also heat the internal environment of the porous packing biofilter 15 to a suitable temperature for microorganisms, ensuring that the microorganisms respond stably to the odorous components. Finally, the exhaust gas can be discharged through the exhaust pipe 17. A demister can be installed at the exhaust pipe 17 to separate the gas and water mist. It is worth mentioning that the valve structure and specific settings involved in the above pipeline are mature existing technologies and will not be described in detail here. By setting the heating pipe 18, the odorous gas can be preheated to appropriately heat the microorganisms in the porous packing biofilter 15, ensuring that the microorganisms are in a suitable working environment and can stably deodorize the odorous gas.

[0025] Please see Figure 3 As shown, a column 2 is fixedly connected to the bottom of the inner wall of the second tank 12; a plurality of first guide plates 22 are fixedly connected to the outer wall of the column 2, and the surface of the first guide plates 22 is arc-shaped; by setting the first guide plates 22, the odor will pass through the first guide plates 22 after entering the second tank 12. Since the surface of the first guide plates 22 is arc-shaped, the odor will flow to the surrounding heating pipes 18 under the guidance of the first guide plates 22, thereby increasing the contact area between the gas and the heating pipes 18 and improving the utilization rate of the heat energy in the heating pipes 18; by setting the first guide plates 22, the flow trajectory of the odor can be changed when it flows in the second tank 12, thereby increasing the heating effect of the heating pipes 18 on the odor.

[0026] Please see Figure 4 and Figure 5 As shown, the pretreatment mechanism includes a first tank 1; the first tank 1 and a second tank 12 are connected by a pipe; a fixing plate 3 is fixedly connected to the inner wall of the first tank 1; a main pipe 32 is fixedly connected to the top of the fixing plate 3; a water inlet pipe 33 is connected to one side of the main pipe 32; a turbine 34 is installed on the inner wall of the main pipe 32; a water distribution plate 35 is fixedly connected to the bottom of the turbine 34; the water distribution plate 35 and the main pipe 32 are rotatably connected; a plurality of inclined branch pipes 36 are connected to the bottom of the water distribution plate 35; the bottom of the branch pipes 36 is perforated; a pair of packing layers 38 are fixedly connected to the inner wall of the first tank 1; a pair of packing layers 38 are provided between them. The second grille 37; after the odor enters the first tank 1 through the air inlet, the water inlet pipe 33 is connected to the water pump, so that the clean water can enter the water distribution plate 35 through the water inlet pipe 33 and the main pipe 32. During the process, the turbine 34 will rotate under the impact of the water flow. At this time, the turbine 34 will rotate the water distribution plate 35 and the branch pipe 36, so that the water flow is sprayed out in a rotating state with the branch pipe 36. At the same time, since the branch pipe 36 is inclined, the spray range of the water flow can be further expanded, thereby increasing the contact area between the water flow and the odor. Meanwhile, the gas-liquid contact area can be expanded in the second grille 37 to help remove impurities from the gas particles. The second grille 37 can be filled with plastic.

[0027] Please see Figure 5 As shown, the top of the water distribution plate 35 is provided with a sealing element 4; the sealing element 4 and the main pipe 32 are fixedly connected; by setting the sealing element 4, the sealing element 4 can seal the connection between the water distribution plate 35 and the main pipe 32, improve the sealing performance of the connection between the water distribution plate 35 and the main pipe 32 when the water distribution plate 35 rotates, and reduce the leakage of water during the spraying process.

[0028] Please see Figure 4 As shown, a plurality of second guide plates 5 are fixed to the inner wall of the first tank 1; the second guide plates 5 are arranged in an alternating inclined manner; by setting the second guide plates 5, the odor entering from the air inlet will flow upward in a serpentine trajectory under the guidance and blocking effect of the second guide plates 5, so as to slow down the odor and thus increase the contact time between the odor and the water in the first tank 1.

[0029] Please see Figure 1 As shown, an insulation board 6 is fixed to the outer wall of the box 13; by setting the insulation board 6, the insulation board 6 will keep the porous packing biological filter bed 15 inside the box 13 warm, so as to reduce the heat exchange between it and the low temperature environment outside.

[0030] Working principle: A centrifugal fan draws odorous gas into the pretreatment unit through the inlet. The pretreatment unit sprays and humidifies the gas to remove particulate matter and some water-soluble pollutants. The pretreated gas then enters the second tank 12 through a pipeline. Inside the second tank 12, a heat circulation system is formed within the heating pipe 18 via a circulation pump, media supply equipment, and heating components. The heating medium flowing within the heating pipe 18 heats the odorous gas through heat conduction. The heated odorous gas then enters the bottom of the housing 13 through a pipeline and passes through the first grid 14 and the porous packing biofilter bed 15. Simultaneously, the spray assembly 16 can be connected to an external water pump for spraying through nozzles. At this point, pollutants in the odorous gas are transferred from the gas phase to the surface. The odorous components, once transferred to the surface of the biofilm, are removed by the absorption and decomposition of microorganisms within the biofilm packing. Simultaneously, the odor also heats the internal environment of the porous packing biofilter bed 15, maintaining a suitable temperature for the microorganisms and ensuring a stable response to the odorous components. Finally, the exhaust gas is discharged through the exhaust pipe 17, where a demister can be installed to separate the gas and water mist. It is worth noting that the valve structure and specific settings involved in the aforementioned pipeline are existing technologies and will not be elaborated here. By setting a first guide plate 22, the odorous gas entering the second tank 12 passes through the first guide plate 22. Because the surface of the first guide plate 22 is arc-shaped, the odorous gas is... Guided by the guide plate 22, the gas flows towards the surrounding heating pipes 18, thereby increasing the contact area between the gas and the heating pipes 18 and improving the utilization rate of the heat energy inside the heating pipes 18. After the odorous gas enters the first tank 1 through the air inlet, the water inlet pipe 33 connects to the water pump, allowing clean water to enter the water distribution plate 35 through the main pipe 32. During this process, the turbine 34 rotates under the impact of the water flow. At this time, the turbine 34 will rotate the water distribution plate 35 and the branch pipe 36, causing the water to spray out in a rotating state with the branch pipe 36. At the same time, since the branch pipe 36 is inclined, the spray range of the water flow can be further expanded, thereby increasing the contact area between the water flow and the odorous gas. Meanwhile, the second grille 37 can expand the spray range. The atmospheric-liquid contact area assists in removing impurities from the gas particles; the second grid 37 can be filled with plastic. By setting a sealing element 4, the connection between the water distribution plate 35 and the main pipe 32 can be sealed, improving the sealing performance of the connection between the water distribution plate 35 and the main pipe 32 when the water distribution plate 35 rotates, and reducing water leakage during the spraying process. By setting a second guide plate 5, the odorous gas entering from the air inlet will flow upward in a serpentine trajectory under the guidance and obstruction of the second guide plate 5, so as to slow down the odorous gas and increase the contact time between the odorous gas and the water in the first tank 1. By setting a heat insulation plate 6, the heat insulation plate 6 will insulate the porous packing biological filter bed 15 in the box 13 to reduce the heat exchange between it and the low temperature environment outside.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
