Description

Technical Field

[0001] This utility model specifically relates to a deodorization device for composting garden waste, belonging to the field of composting deodorization technology. Background Technology

[0002] With the acceleration of urbanization, the amount of garden waste (fallen leaves, pruned branches, etc.) is increasing year by year. Composting, as an ecological and resource-based treatment method, transforms garden waste into organic fertilizer rich in humus through microbial decomposition. It can reduce the pressure on landfills and turn waste into treasure, providing sustainable resources for soil improvement and landscaping. It is an important practice of the circular economy concept in the field of solid waste treatment.

[0003] However, current garden waste composting sites generally face the problem of odor pollution in actual operation. During the composting fermentation process, complex organic matter decomposes under the action of microorganisms to produce odorous substances such as hydrogen sulfide. These gases have an irritating smell. Most existing composting facilities adopt an open-air or semi-enclosed mode and lack an effective odor collection and treatment system, which leads to the unorganized spread of odors. The pollution range can spread to an area of ​​500 meters or even further, seriously affecting the quality of life of residents.

[0004] To address the above problems, this application proposes a deodorization device for composting garden waste. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a deodorization device for garden waste composting. Under the negative pressure of the intake fan, odorous air in the composting area is filtered through three sets of inclined filter meshes to remove impurities. The filtered air then enters the purification component, where a transfer pump drives an atomizing nozzle to release deodorizing water mist. The water mist reacts with odor molecules to deodorize, while simultaneously capturing residual micro-impurities that are adsorbed by the central and side adsorption plates. Finally, the purified air is discharged through the exhaust pipe by the exhaust fan, effectively solving the problem of odor escape from the composting area and addressing the issues raised in the background art.

[0006] A deodorization device for composting garden waste includes: a deodorization mechanism comprising a pretreatment component and a purification component; the pretreatment component includes an air inlet box, wherein three sets of fixed frames are installed obliquely on the upper part of the air inlet box, and each set of fixed frames is equipped with a filter screen for filtering impurities in the gas; a sliding plate is installed obliquely on the lower part of the air inlet box; and an air intake fan is provided on one side of the air inlet box for extracting gas from the composting area; the purification component includes a bottom box, wherein a liquid storage chamber for storing deodorizing liquid is opened on one side of the bottom box, and multiple sets of atomizing nozzles for spraying deodorizing liquid to deodorize the gas are provided on the upper part of the other side of the bottom box; a central adsorption plate is provided below the atomizing nozzles, and a side adsorption plate is installed on one side above the central adsorption plate; the side adsorption plate and the central adsorption plate can adsorb impurities in the gas after being treated by atomization and humidification of the deodorizing liquid; and an exhaust fan is installed on one side of the bottom box for discharging the purified gas.

[0007] In a preferred embodiment, an air inlet is provided on one side of the air inlet box, and the aperture of the three sets of air filter meshes decreases sequentially from front to back.

[0008] In a preferred embodiment, the intake fan is connected to the intake box via an intake pipe and to the inside of the bottom box via an air guide pipe, and the bottom of the intake fan is fixedly connected to the bottom box via a bracket.

[0009] As a preferred embodiment, the bottom box is provided with two sets of partitions, one side of which is a liquid storage chamber and the other side is a purification chamber, and the central adsorption plate and the side adsorption plate are installed in the purification chamber.

[0010] As a preferred embodiment, a fixed water pipe is installed on one side of the multiple sets of atomizing nozzles, and the fixed water pipe is fixedly connected to the inner wall of the purification chamber. A transfer pump is provided between the two sets of partitions, and the transfer pump is connected to the inside of the liquid storage chamber through a water pumping pipe and connected to the fixed water pipe through a transfer pipe.

[0011] In a preferred embodiment, an exhaust pipe is installed on one side of the exhaust fan, and the exhaust fan is connected to the interior of the purification chamber through an exhaust pipe.

[0012] In a preferred embodiment, a water level plate is installed on the front side of the bottom tank, located on one side of the liquid storage chamber, and a drain valve is installed on the back side, located below the side of the purification chamber. An inlet pipe is installed on the top of the bottom tank, and the inlet pipe is connected to the inside of the liquid storage chamber.

[0013] In a preferred embodiment, both the central adsorption plate and the side adsorption plate are made of activated carbon, and the side adsorption plate is installed vertically.

[0014] Beneficial effects:

[0015] 1. By designing a pretreatment component, under the negative pressure of the intake fan, odorous air from the composting area gathers at the air inlet and enters the pretreatment component through the air inlet box. This component contains three sets of inclined filter meshes forming a three-stage filtration system. The first layer of large-pore meshes intercepts large particles of impurities, the middle layer of medium-pore meshes intercepts medium-sized impurities, and the final layer of small-pore meshes intercepts smaller particles of impurities, forming a three-stage fine filtration. Furthermore, the inclined design makes it difficult for impurities to remain on the inclined surface after the deodorization process. Under the action of gravity, the impurities slide down to the sliding plate below and slide out of the box along the inclined plate surface, eliminating the need for frequent manual cleaning and ensuring the permeability of the filter mesh.

[0016] 2. By designing purification components, the gas filtered by the pretreatment components enters the purification chamber. The transfer pump delivers the deodorizing liquid to the atomizing nozzle, forming a water mist that diffuses within the chamber. This fine water mist not only comes into full contact with malodorous molecules such as hydrogen sulfide and ammonia, causing neutralization or dissolution reactions, but also captures residual tiny impurities in the gas. These impurities absorb moisture, increase in weight, and then settle onto the surfaces of the central and side adsorption plates below, completing secondary impurity interception and purification. The clean air treated within the purification chamber is then discharged through the exhaust pipe under the powerful traction of the exhaust fan, achieving highly efficient purification of odorous gases in the composting area and preventing the unorganized spread of odors that could affect the lives of surrounding residents.

[0027] Please see Figure 3 As shown, the bottom box 21 is equipped with two sets of partitions. One side of the two sets of partitions is a liquid storage chamber 26, and the other side is a purification chamber. The central adsorption plate 28 and the side adsorption plate 29 are installed in the purification chamber. The partitions can separate the purification chamber from the liquid storage chamber 26.

[0028] Please see Figure 3 and Figure 5As shown, a fixed water pipe 210 is installed on one side of multiple sets of atomizing nozzles 211, and the fixed water pipe 210 is fixedly connected to the inner wall of the purification chamber.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] When in use, the device is placed in the composting area. It can be started and stopped as needed according to the scale of composting, fermentation stage and odor concentration. When started, the air intake fan 13 can draw gas from the composting area through the suction pipe 17 and let the gas enter the air intake box 11 through the air inlet 12. The gas is filtered in the box by three sets of filter meshes 16 with successively decreasing pore sizes and installed at an angle. The particulate impurities mixed in the gas are finely intercepted three times. After deodorization, the impurities are difficult to remain on the inclined surface. The intercepted impurities fall down to the inclined sliding plate 14 under the action of gravity and are discharged, thus cleaning the impurities and keeping the filter meshes 16 transparent. The filtered gas is transported to the purification chamber through the air guide pipe 18.

[0034] Deodorizing liquid (such as plant extract, which is extracted from natural essential oils or polyphenols from plants such as citrus, mint, and artemisia, and neutralizes odor molecules through intermolecular forces) can be added to the storage chamber 26 in advance through the inlet pipe. The deodorizing liquid in the storage chamber 26 can be drawn by the transfer pump 27 through the water pipe, transported to the fixed water pipe 210 through the transfer pipe, and then sprayed into the purification chamber by the atomizing nozzle 211 to form water mist. The water mist reacts with the odor molecules in the gas to neutralize or dissolve, thereby achieving deodorization. At the same time, it wets the tiny impurities remaining in the gas, making them heavier, and they are adsorbed by the central adsorption plate 28 of activated carbon material and the vertically installed side adsorption plates 29. The gas during the purification process can be drawn by the exhaust fan 22 through the exhaust pipe 24 and discharged through the exhaust pipe 25, thereby achieving deodorization and purification of the gas in the composting area.
