Abstract
Description
Technical Field
[0001] The utility model relates to the field of filtering devices, in particular to a gas filtering system in a composting process. Background Art
[0002] Composting is a process that converts organic waste into stable, nutrient-rich fertilizer. During the composting process, microorganisms break down these organic materials, generating heat, carbon dioxide, water and humus. However, this process may also produce some undesirable gases, such as odor, which requires deodorization of the compost exhaust.
[0003] The composting process gas filtration system is a system specially designed for treating the gases generated in the composting process. The function of the composting process gas filtration system is to remove or reduce the concentration of these gases to reduce their harm to the environment and human body. The existing composting process gas filtration system, when deodorizing the gas, generally makes the waste gas contact with atomized deodorizing liquid or directly passes the waste gas into the deodorizing liquid, so that the waste gas and the deodorizing liquid are mixed with each other to achieve the purpose of deodorization. However, when deodorizing, the waste gas is directly passed into the deodorizing liquid, and then overflows from the deodorizing liquid through the flow of the gas itself. The mixing time of the waste gas and the deodorizing liquid is short, which makes the deodorization effect of the waste gas poor.
[0004] Therefore, it is necessary to provide a new composting process gas filtration system to solve the above technical problems. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0024] Please refer to Figure 1-Figure 5 ,in, Figure 1 A schematic diagram of the structure of the gas filtration system for the composting process provided by the utility model; Figure 2 for Figure 1 The local structural schematic diagram shown; Figure 3 for Figure 1 The structural schematic diagram of the filter box, compost box and purification box shown; Figure 4 for Figure 1 A schematic diagram of the structure of the cross section shown; Figure 5 for Figure 2 A schematic structural diagram of the local structure inside the filter box is shown.
[0025] In the specific implementation process, Figure 1-Figure 5As shown, it includes a filter box 1 and a gas transmission device and a purification device connected to the filter box 1. Two mounting plates 2 are fixedly installed on the inner side of the filter box 1. Multiple bent plates 3 are installed on the opposite side walls of the two mounting plates 2. The bent plates 3 are composed of multiple V-shaped plate bodies. The multiple bent plates 3 on the upper mounting plate 2 are staggered with the multiple bent plates 3 on the lower mounting plate 2, and there are gaps between the multiple bent plates 3 on the upper mounting plate 2 and the lower mounting plate 2, and there are gaps between the multiple bent plates 3 on the lower mounting plate 2 and the upper mounting plate 2. A through hole for gas discharge is opened on the upper mounting plate 2. The filter box 1 is connected to a spray device installed on the top wall of the filter box 1 through a circulation device arranged on one side. Multiple baffles 22 are fixedly connected between the multiple bent plates 3. The baffles 22 are inclined in the opposite direction of the gas flow. The baffles 22 are arranged to reduce the gas flow speed.
[0026] In addition, the gas moves upward from the gap between the upper mounting plate 2 and the bent plate 3 to between the two bent plates 3. During the gas movement, since the bent plate 3 is composed of a plurality of V-shaped plate bodies, it has a certain blocking effect on the flow of the gas, so that the gas flow speed is reduced. Then, the gas moves between the two bent plates 3 to the gap between the lower mounting plate 2 and the bent plate 3, and then moves upward between the next two bent plates 3. In this way, after repeated multiple times, the gas moves out from the through hole of the upper mounting plate 2. The speed of the gas flowing in the deodorant liquid is slowed down by the mounting plate 2 and the plurality of bent plates 3, thereby enhancing the deodorizing effect.
[0027] The air delivery device includes a compost box 4 and a vent pipe 5. A through hole opened on one side of the compost box 4 is connected with a sealing plate by bolts. The top wall of the compost box 4 is fixedly connected to the vent pipe 5. The output end of the vent pipe 5 is arranged at a position near the bottom of the inner cavity of the filter box 1. The circulation device includes two high-pressure water pumps 23 and two liquid infusion pipes 24. The two high-pressure water pumps 23 are installed on the filter box 1, and the input ends of the two high-pressure water pumps 23 are connected to the inner cavity of the filter box 1. The output ends of the two high-pressure water pumps 23 are respectively connected to the two liquid infusion pipes 24. The liquid infusion pipes 24 are installed on the top wall of the filter box 1. The spray device includes two liquid guide pipes 8 and a rotating assembly for driving the liquid guide pipes 8 to rotate. The two liquid guide pipes 8 are connected to the two liquid infusion pipes 24.

The first sprocket 11 is fixedly installed on the two support rods 10. The mounting frame 14 is fixedly installed on the filter box 1. The motor 15 is installed on the mounting frame 14. The output end of the motor 15 is installed with the second sprocket 12. The second sprocket 12 and the two first sprockets 11 are connected by a chain 13. The motor 15 drives the second sprocket 12 to rotate in forward and reverse rotation, and the two first sprockets 11 are rotated through the chain 13, so that the two liquid guide tubes 8 rotate forward and reverse with the atomizing nozzle facing downward, thereby enhancing the deodorization effect.
[0029] The filter box 1 is provided with a fixedly connected inclined plate 7 and a filter plate 6, the inclined plate 7 and the filter plate 6 are fixedly connected to the inner wall of the filter box 1, the ventilation pipe 5 is fixedly inserted through the filter plate 6, the filter plate 6 is provided with a through hole, and the filter box 1 is installed with a second water pipe 17 for adding deodorant liquid and a first water pipe 16 for draining liquid;

The activated carbon plate 20 is installed between the two support plates 19. A pipeline for gas overflow is fixedly connected to the purification box 18. The gas moves between the two mounting plates 2 through the air duct 21. The gas enters the purification box 18 through the air duct 21 and is further deodorized by the activated carbon.
[0031] The working principle of the utility model is as follows: when the device is used, the gas enters between the two mounting plates 2 in the filter box 1 through the ventilation pipe 5 on the compost box 4, and then the gas moves upward from the gap between the upper mounting plate 2 and the bent plate 3 to between the two bent plates 3. During the gas movement, the baffle 22 is set to reduce the gas flow rate. Then, the gas moves between the two bent plates 3 to the gap between the lower mounting plate 2 and the bent plate 3, and then moves upward between the next two bent plates 3. In this way, after repeated multiple times, the gas moves out from the through hole of the upper mounting plate 2 and passes through the filter plate 6. The high-pressure water pump 23 moves the deodorizing liquid from the bottom of the filter box 1 to the connecting pipe 9, and then passes through the liquid guide pipe 8 and the atomizing nozzle to be sprayed out to react with the exhaust gas to achieve the purpose of further deodorization. In addition, the motor 15 drives the second sprocket 12 to rotate in forward and reverse directions, and the two first sprockets 11 are rotated through the chain 13, so that the two liquid guide pipes 8 rotate forward and reverse with the atomizing nozzles facing downward, thereby enhancing the deodorizing effect.
