Description

Technical Field

[0001] The utility model relates to the technical field of sludge deodorization, in particular to a deodorization device for sludge treatment. Background Art

[0002] Malodorous gases are produced during the sludge treatment process. These gases are mainly composed of harmful substances such as hydrogen sulfide, ammonia, and methyl mercaptan. They not only pollute the environment, but may also harm the health of operators. Therefore, deodorization devices play a vital role in sludge treatment. These devices effectively remove the malodorous gases produced during the sludge treatment process through physical, chemical or biological methods, thereby improving the working environment and protecting the ecological environment.

[0003] After searching, it was found that the patent with announcement number CN216236584U discloses a deodorizing device for sludge treatment. The deodorizing device only filters the odor through a filter box and a filter plate, resulting in an unsatisfactory deodorizing effect and the emitted gas is difficult to meet safety standards.

[0004] In response to the above problems, this utility model document proposes a deodorizing device for sludge treatment. Utility Model Content

[0005] The utility model provides a deodorizing device for sludge treatment, which solves the shortcomings of the prior art that odor is only filtered through a filter box and a filter plate, resulting in unsatisfactory deodorizing effect and difficulty in the emission of gas meeting safety standards.

[0006] The utility model provides the following technical solutions:

[0007] Deodorization equipment for sludge treatment, including:

[0008] A tank body, wherein a plurality of annular drying plates for drying sludge are embedded in an annular array on the inner wall of the tank body, and a feed pipe is connected to the top of the tank body, and a feed valve is provided on the feed pipe to ensure the airtightness of the tank;

[0009] A spraying component is provided on the tank body and is used to spray the deodorizing agent into the tank;

[0010] The mixing and breaking component is installed in the tank body and is used to improve the reaction efficiency of the deodorizing agent and the sludge and break up the dried sludge;

[0011] The double filter assembly is installed outside the tank to purify the residual odor emitted by the sludge.

[0012] In one possible design, the spray assembly includes two medicine storage boxes symmetrically fixed on the outer wall of the tank body, a water pump used in conjunction with the corresponding medicine storage box is fixedly installed on the top of the tank body, the input end of the water pump is connected to the inner wall of the corresponding medicine storage box through a water pipe, and a spray plate used in conjunction with the corresponding water pump is fixedly installed on the top of the inner wall of the tank body, the input end of the spray plate is connected to the input end of the corresponding water pump through a water pipe, and the nozzles at the bottom of the spray plate are arranged in a circular array.

[0013] In one possible design, the mixing and crushing assembly includes a transmission rod rotatably mounted in the center of the top inner wall of the tank body, a drive motor for driving the transmission rod to rotate is fixedly mounted on the top of the tank body, and two grid-shaped stirring blades are symmetrically fixed on the transmission rod.

[0014] In one possible design, the double filtration component includes an air pump arranged outside the tank body, the input end of the air pump is connected to the inner wall of the feed pipe through an air pipe, and the output end of the air pump is connected to an activated carbon filter box, and a plurality of activated carbon filter plates are installed on the top of the activated carbon filter box. A medicine box filled with purifier is provided on the other side of the activated carbon filter box, and the top of the medicine box is not closed to facilitate the discharge of purified gas. A hose is connected to the exhaust port of the activated carbon filter box, and the other end of the hose extends into the medicine box.

[0015] In a possible design, a support base is fixedly provided on the bottom of the tank body, and an anti-slip pad is fixedly provided on the bottom of the support base leg.

[0016] In a possible design, a discharge pipe is connected to the center of the bottom of the tank body, and a matching discharge valve is provided on the discharge pipe.

[0017] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0018] The working principle and usage process of this technical solution are as follows:

[0019] During use, the feed valve is opened and the sludge to be treated is introduced into the tank through the feed pipe. After the sludge enters the tank, the built-in multiple annular drying sheets start to work, and the sludge is dried by an external heat source to reduce the moisture content in the sludge, which also helps to reduce the generation of odor. The spraying component starts to work synchronously, and the two medicine storage boxes respectively store different deodorizing agents (or different batches of the same agent). The corresponding water pumps extract the agents and transport them to the spray plate on the top of the inner wall of the tank. The nozzles at the bottom of the spray plate are arranged in a circular array to ensure that the deodorizing agent can be evenly sprayed on the sludge surface and fully contact with the sludge. While spraying the deodorizing agent, the mixing and crushing components are started, and the drive motor drives the transmission rod to rotate. The two grid-shaped stirring blades on the transmission rod stir and crush the sludge, promoting the full mixing and reaction of the deodorizing agent and the sludge, thereby improving the deodorizing efficiency.

[0020] During the sludge treatment process, some odor may still be emitted from the tank. At this time, the double filtration component starts to work. The vacuum pump extracts the odor in the tank from near the feed pipe through the air pipe, and then sends the odor into the activated carbon filter box. The multiple activated carbon filter plates in the activated carbon filter box adsorb harmful substances in the odor. The gas that has been preliminarily purified enters the medicine box through a hose. The purifier in the medicine box further treats the gas to ensure that the discharged gas meets environmental protection standards. The top of the medicine box is not closed so that the purified gas can be discharged naturally. After the treatment is completed, open the discharge valve and discharge the treated sludge or wastewater through the discharge pipe at the bottom of the tank.

[0021] The utility model has the following beneficial effects:

[0022] The utility model can effectively remove the odor generated in the sludge treatment process through the comprehensive effect of drying, spraying deodorizing agents, mixing and crushing, thereby improving the working environment and protecting the ecological environment. It also adopts a double filtering component consisting of an activated carbon filter box and a medicine box to purify the odor twice, ensuring that the discharged gas meets environmental protection standards and reduces air pollution.

[0023] The utility model can effectively dry, deodorize and purify the sludge, reduce odor pollution in the sludge treatment process, and improve the efficiency and environmental protection of the sludge treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example 1

[0033] Please refer to Figure 1-4 , deodorization device, comprising:

[0034] The tank body 1 is the main part of the entire device. The tank body 1 is made of corrosion-resistant and high-temperature resistant materials to ensure stable operation during the sludge treatment process. On the inner wall of the tank body 1, a plurality of annular drying sheets 2 are embedded in a ring array. These drying sheets 2 are heated by an external heat source (such as steam, electric heating, etc.) to dry the sludge entering the tank body 1, reduce the moisture content in the sludge, and also help to reduce the generation of odor. A feed pipe 3 is designed on the top of the tank body 1, and a feed valve 4 is installed on the feed pipe 3 to control the entry of sludge and ensure the airtightness of the tank to prevent odor leakage during the treatment process.

[0035] In order to achieve the deodorization function, the device is designed with a spraying component, which includes two medicine storage boxes 9 symmetrically fixed on the outer wall of the tank body 1. Each medicine storage box 9 is filled with a deodorizing agent. A water pump 10 used in conjunction with the corresponding medicine storage box 9 is fixedly installed on the top of the tank body 1. The water pump 10 is connected to the inner wall of the medicine storage box 9 through a water pipe to extract the deodorizing agent. At the same time, a spraying plate 11 is fixedly installed on the top of the inner wall of the tank body 1. The input end of the spraying plate 11 is connected to the corresponding water pump 10 through a water pipe, and the nozzles at the bottom are arranged in a circular array to ensure that the deodorizing agent can be evenly sprayed on the sludge in the tank, thereby improving the deodorizing effect.

[0036] In order to improve the reaction efficiency between the deodorizing agent and the sludge and break up the dried sludge, the device is also designed with a mixing and crushing component, which includes a transmission rod 5 rotatably mounted on the top center of the inner wall of the tank body 1. The transmission rod 5 is driven to rotate by a drive motor 6 fixedly mounted on the top of the tank body 1. Two grid-shaped stirring blades 7 are symmetrically fixed on the transmission rod 5. As the transmission rod 5 rotates, the stirring blades 7 stir and break up the sludge, thereby promoting full contact and reaction between the deodorizing agent and the sludge.

[0037] In order to purify the residual odor emitted by the sludge, the device is also designed with a double filtering component, which includes an air pump 12 arranged outside the tank body 1. The input end of the air pump 12 is connected to the inner wall of the feed pipe 3 through an air pipe to extract the odor in the tank. The output end of the air pump 12 is connected to an activated carbon filter box 13. A plurality of activated carbon filter plates are installed in the activated carbon filter box 13 to adsorb harmful substances in the odor. A medicine box 14 is provided on the other side of the activated carbon filter box 13. The medicine box 14 is filled with a purifier to further purify the gas treated by the activated carbon filter box 13. A hose is connected to the exhaust port of the activated carbon filter box 13. The other end of the hose extends into the medicine box 14. The top of the medicine box 14 is not closed to ensure that the purified gas can be discharged smoothly.

[0038] This application can be used for sludge treatment, and can also be used in other fields applicable to this application.
