Description

Technical Field

[0001] The utility model relates to the technical field of biological deodorization of kitchen waste, in particular to an embedded biological deodorization filter pool water distribution device. Background Art

[0002] Currently, food waste disposal plays a vital role in modern life, particularly in areas such as daily life, food processing, and catering services, where the amount of food waste generated is increasing. Food waste, which includes discarded vegetable leaves, leftovers, fruit peels, tea leaves, bones, and other items, is characterized by high moisture content, high organic matter content, and the tendency to rot and deteriorate. If this waste is not promptly and effectively treated, it will have serious impacts on the environment and human health. Bio-deodorization technology is widely used to treat malodorous gases generated by food waste, particularly through the use of biofilters to decompose and remove harmful substances from odorous gases, effectively reducing odor emissions and improving environmental quality.

[0003] Among existing kitchen waste deodorization technologies, biofilters are often used to treat high-concentration odors. Traditional biofilter designs typically include a packing layer for adsorbing and decomposing odorous components in the gas, and a water distribution system to maintain the moisture of the biofilter media. However, existing biofilter designs often overlook the impact of water vapor on the back-end treatment system. In particular, when water vapor enters the activated carbon adsorption box at the back end along with the airflow, it may cause the activated carbon to become damp and moldy, thereby affecting the activated carbon's adsorption capacity and service life. After long-term operation, this water vapor intrusion phenomenon not only shortens the activated carbon replacement cycle, but also reduces the overall efficiency of the deodorization system, resulting in increased maintenance costs and decreased performance. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide an embedded biological deodorization filter water distribution device, aiming to solve the technical problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An embedded biological deodorization filter water distribution device comprises a biological filter, an air inlet pipe is provided at the bottom of one side of the biological filter, a drainage pipe is provided at the bottom of the other side of the biological filter, and an air outlet pipe is provided on one side of the surface of the biological filter;

[0007] The interior of the biological filter is provided with a second air-permeable grille and a first air-permeable grille in order from high to low, and a first biological filler layer and a second biological filler layer are provided on the surfaces of the second air-permeable grille and the first air-permeable grille respectively, and a predetermined gap is provided between the first biological filler layer and the second biological filler layer;

[0008] A water supply pipe is connected to the side of the biological filter, and a plurality of water distribution pipes are arranged on the surface of the water supply pipe. One end of the water distribution pipe is connected to a second water distribution pipe, and a plurality of first water distribution pipes are arranged on the surface of the second water distribution pipe. A plurality of water spray holes are opened on the surfaces of the second water distribution pipe and the first water distribution pipe.

[0009] Furthermore, the second water distribution pipe passes through the first biological filler layer and the second biological filler layer in sequence.

[0010] Furthermore, the opening directions of the water spray holes provided on the surface of the first water distribution pipe correspond to the surfaces of the first biological filler layer and the second biological filler layer.

[0011] Furthermore, the water distribution pipe and the second water distribution pipe are both provided with a detachable adapter at one end close to each other, and the second water distribution pipe is detachably connected to the water distribution pipe through the detachable adapter.

[0012] Furthermore, a plurality of support frames are provided on the inner bottom of the biological filter, and one end of the support frame contacts the surface of the first air-permeable grille.

[0013] Furthermore, the total thickness of the first biological filler layer and the predetermined gap is one third of the thickness of the second biological filler layer.

[0014] The utility model provides an embedded biological deodorization filter water distribution device, which has the following beneficial effects:

[0015] Through the rational internal structural design of the biofilter, the biological packing layer is divided into three layers: a second biological packing layer for deodorization, a water distribution layer (predetermined gap layer), and a first biological packing layer for blocking water vapor. This layered design effectively improves deodorization efficiency. The second biological packing layer is primarily responsible for treating odors in the gas, while the first biological packing layer blocks water vapor generated by the water distribution layer, reducing the risk of water vapor entering the rear activated carbon tank, thereby extending the service life of the activated carbon. In addition, this design can further improve the overall treatment effect of the filter, ensuring that odor and moisture in the gas are efficiently treated in layers.

[0016] Secondly, the device's water distribution system utilizes a hierarchical structure consisting of a water distribution pipe, a secondary water distribution pipe, and a primary water distribution pipe. The spray holes are precisely positioned at key locations within each bio-packing layer. This water distribution ensures that water is evenly sprayed across the packing surface, effectively maintaining the bio-packing's moisture content, thereby promoting microbial growth and reproduction and ensuring a consistent and stable deodorizing effect. Furthermore, the strategically placed spray holes prevent excessive or insufficient water accumulation, improving system efficiency.

[0017] Finally, the device's rational configuration of inlet, outlet, and drainage pipes allows for smoother gas and water flow, effectively reducing resistance during operation. This design not only improves the system's airflow and permeability, but also ensures long-term, stable operation of the deodorization system and reduces maintenance frequency.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0022] like Figure 1 As shown, an embedded biological deodorization filter water distribution device provided by an embodiment of the present invention includes a biological filter 1, an air inlet pipe 5 is provided at the bottom of one side of the biological filter 1, and a drainage pipe 14 is provided at the bottom of the other side of the biological filter 1, and an air outlet pipe 9 is provided on one side of the surface of the biological filter 1.

[0023] The interior of the biological filter 1 is provided with a second air-permeable grille 15 and a first air-permeable grille 13 in order from high to low, and the surfaces of the second air-permeable grille 15 and the first air-permeable grille 13 are provided with a first biological filler layer 11 and a second biological filler layer 12 respectively, and a predetermined gap is provided between the first biological filler layer 11 and the second biological filler layer 12. The total thickness of the first biological filler layer 11 and the predetermined gap is one-third of the thickness of the second biological filler layer 12. Through this design, the biological filler layer is divided into three layers: the first layer is the second biological filler layer 12, which is mainly used for deodorization; the second layer is the water distribution layer (predetermined gap layer); the third layer is the first biological filler layer 11, whose main function is to block the water vapor generated by the middle water distribution layer, reduce the water vapor content in the odor, and reduce the risk of water vapor entering the rear-end activated carbon.

[0024] A water supply pipe 10 is connected to the side of the biological filter 1, and several water distribution pipes 6 are arranged on the surface of the water supply pipe 10. One end of the water distribution pipe 6 is connected to the second water distribution pipe 4, which passes through the first biological filler layer 11 and the second biological filler layer 12 in sequence.

[0025] The surface of the second water distribution pipe 4 is provided with a plurality of first water distribution pipes 3. Both the second water distribution pipe 4 and the first water distribution pipe 3 are provided with a plurality of water spray holes 2. The opening direction of the water spray holes 2 on the surface of the first water distribution pipe 3 corresponds to the surface of the first biological filler layer 11 and the second biological filler layer 12. According to this design, the water spray holes 2 on the surface of the first water distribution pipe 3 can spray water evenly on the lower surface of the first biological filler layer 11 and the top of the second biological filler layer 12, thereby achieving a uniform water distribution effect.

[0026] In one embodiment of the present invention, when the deodorization system is activated, gas enters the biofilter 1 through the air inlet pipe 5. The gas flows from bottom to top through a second air-permeable grille 15 and a first air-permeable grille 13 disposed within the biofilter 1. The surfaces of these two air-permeable grilles are provided with a second bio-filler layer 12 and a first bio-filler layer 11, respectively. The second bio-filler layer 12, as the bottommost layer, is primarily used to adsorb and decompose harmful components in the odor, achieving preliminary purification of the gas. The gas continues to flow upward, entering the water distribution layer (predetermined gap layer), where the gas humidity is further adjusted to reduce the water vapor content.

[0027] The water distribution system provides water to the interior of the biofilter through a side water supply pipe 10. Multiple water distribution pipes 6 are installed on the surface of the water supply pipe 10, which transport water to the second water distribution pipe 4. The second water distribution pipe 4 penetrates the interior of the first biofiller layer 11 and the second biofiller layer 12 and evenly sprays water onto the surfaces of the two layers of biofiller through the water spray holes 2 on its surface. Specifically, the water spray holes 2 on the surface of the first water distribution pipe 3 correspond to the lower surface of the first biofiller layer 11 and the top surface of the second biofiller layer 12, ensuring that the water is evenly distributed, thereby providing sufficient moisture to the biofiller layers.

[0028] During the water distribution process, the primary function of the first biofiller layer 11 is to block water vapor generated by the water distribution layer, preventing excessive moisture from entering the activated carbon tank at the rear end. This design not only effectively reduces the water vapor content in the odor but also reduces the risk of moisture contamination on the activated carbon at the rear end, thereby extending the life of the activated carbon.

[0029] After the gas is treated by the biofilter, the odorous components are decomposed and adsorbed, and finally discharged through the outlet pipe 9, completing the entire gas purification process. After being adsorbed by activated carbon, the discharged gas can meet the emission standards and then enter the atmosphere through the exhaust pipe to achieve the final deodorization effect.

[0030] In summary, through the rational internal structural design of the biofilter 1, the biofill layer is divided into three layers: a second biofill layer 12 for deodorization, a water distribution layer (predetermined gap layer), and a first biofill layer 11 for blocking water vapor. This layered design effectively improves deodorization efficiency. The second biofill layer primarily handles odor in the gas, while the first biofill layer blocks water vapor generated by the water distribution layer, reducing the risk of water vapor entering the rear activated carbon tank, thereby extending the service life of the activated carbon. Furthermore, this design further enhances the overall treatment effect of the filter, ensuring that odor and moisture in the gas are efficiently treated in layers.

[0031] Secondly, the device's water distribution system utilizes a hierarchical structure consisting of a water distribution pipe 6, a second water distribution pipe 4, and a first water distribution pipe 3. The spray holes 2 are precisely positioned at key locations within each biofiller layer. This water distribution design ensures that water is evenly sprayed across the biofiller surface, effectively maintaining the biofiller's moisture level, thereby promoting microbial growth and reproduction and ensuring a consistent and stable deodorizing effect. Furthermore, the optimal placement of the spray holes prevents excessive or insufficient water accumulation, improving system efficiency.

[0032] Finally, the device's rational configuration of inlet, outlet, and drainage pipes allows for smoother gas and water flow, effectively reducing resistance during operation. This design not only improves the system's airflow and permeability, but also ensures long-term, stable operation of the deodorization system and reduces maintenance frequency.

[0033] In this embodiment, a detachable adapter 7 is provided on the ends of the water distribution pipe 6 and the second water distribution pipe 4 close to each other, and the second water distribution pipe 4 is detachably connected to the water distribution pipe 6 through the detachable adapter 7 .

[0034] This design, first of all, makes the maintenance and cleaning of the water distribution piping system much easier. During long-term operation, the pipes may become clogged due to scale, impurities, or other reasons. The detachable connection makes it easy to remove the pipes for cleaning, ensuring the continued efficient operation of the water distribution system.

[0035] Secondly, if a part of the water distribution pipe or water distribution hole is damaged during the operation of the system, there is no need to replace the entire system. Instead, the damaged parts can be replaced individually through detachable adapters, reducing repair costs and improving maintenance efficiency.

[0036] In addition, the detachable design provides flexibility, allowing the water distribution system to be adjusted or optimized as needed to meet the needs of different deodorization processes. This flexibility enables the device to better adapt to diverse operating environments and ensure more stable performance.

[0037] Finally, during the installation process, the use of a detachable adapter can simplify the installation process, reduce installation time and difficulty, and does not require additional complex tools. It is convenient and quick, further improving the system's operating efficiency and user experience.

[0038] In this embodiment, a plurality of support frames 8 are provided at the inner bottom of the biological filter 1 , and one end of the support frame 8 is in contact with the surface of the first air grille 13 .

[0039] Through this design, the support frame 8 provides a stable support structure for the first ventilation grille 13, ensuring that the ventilation grille remains stable and does not deform during operation, thereby ensuring smooth gas flow. The stability of the ventilation grille is crucial to the proper functioning of the biofiller layer. The support frame effectively prevents damage or failure of the grille due to uneven pressure or sinking of the filler.

[0040] Secondly, the use of support frame 8 helps improve the durability of the internal structure of the biofilter. Because the biofilter is in a humid environment for a long time, the weight of the filler and the grille may cause uneven stress on the bottom. The support frame provides additional support, distributing the load on the biofiller layer and the ventilation grille, thereby extending the service life of the device.

[0041] In addition, the design of the support frame 8 helps maintain good air permeability between the first air grille and the bottom. This arrangement ensures that the gas can be evenly deodorized through the biofiller layer, avoiding the impact of excessive compaction of the bottom filler on gas circulation, and improving the deodorization efficiency of the entire system.

[0042] Finally, the design and installation of the support frame facilitates overall maintenance of the system. If the first ventilation grille or the bottom of the biofilter needs to be cleaned or maintained, the support frame provides stable structural support, making it easy for operators to enter the system for maintenance work.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
