Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to an odor removal device for landfill leachate. Background Technology

[0002] Landfill leachate is a high-concentration organic wastewater produced during the landfilling and disposal of waste through biodegradation and rainwater runoff. Its complex composition includes ammonia nitrogen, volatile fatty acids, and thiols, resulting in a strong, pungent odor. This odor not only causes foul-smelling pollution to the surrounding environment but can also harm human health through the respiratory tract. Therefore, it is essential to treat landfill leachate for odor removal to meet environmental emission requirements. Currently, traditional odor removal methods often involve directly adding deodorizing agents. However, due to the lack of a quantitative dosing mechanism, controlling the amount of deodorizing agent used is difficult: insufficient dosage leads to incomplete odor removal, while excessive dosage results in wasted agents, increased treatment costs, and potential introduction of new chemical pollution, affecting subsequent water treatment. Therefore, a landfill leachate odor removal device is needed.

[0003] In existing technologies, some odor removal devices use manual or extensive methods to add deodorizing agents. Due to the lack of a quantitative control structure, the amount of deodorizing agent added cannot be matched with the odor concentration of the permeate. When the permeate water quality fluctuates or the odor intensity changes, non-quantitative addition will result in low utilization of the deodorizing agent. Especially when the odor concentration is high, non-quantitative addition may fail to quickly neutralize odor substances due to insufficient agent, leading to reduced treatment efficiency. On the other hand, when the odor concentration is low, excessive addition of deodorizing agent not only increases treatment costs but may also disrupt the chemical balance of the permeate, affecting the stability of subsequent treatment processes. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an odor removal device for landfill leachate, which aims to improve the problem of mismatch between the amount of deodorizing agent added and the amount of leachate required.

Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2An embodiment of this utility model provides an odor removal device for landfill leachate, comprising a U-shaped block 1, a cylinder 2 fixedly connected to the inner wall of the U-shaped block 1, a connecting plate 3 fixedly provided at the output end of the cylinder 2, the outer wall of the connecting plate 3 slidably connected to the inner wall of the U-shaped block 1, a feeding trough 4 opened inside the connecting plate 3, a metering tank 5 fixedly connected to the lower surface of the connecting plate 3, a hinge 6 fixedly connected to the outer wall of the metering tank 5, a tank bottom 7 fixedly connected to the outer wall of the hinge 6, the upper surface of the tank bottom 7 rotatably connected to the lower surface of the metering tank 5, a fixing plate 8 fixedly connected to the lower surface of the U-shaped block 1, a sliding plate 9 fixedly connected to the outer wall of the fixing plate 8, the lower surface of the tank bottom 7 slidably connected to the inner wall of the sliding plate 9, and a storage component fixedly provided on the outer wall of the U-shaped block 1.

[0024] Specifically, the U-shaped block 1 fixes the cylinder 2. The linear motion of the cylinder 2 output drives the connecting plate 3 to slide along the groove on the inner wall of the U-shaped block 1, realizing the horizontal reciprocating movement of the connecting plate 3. The feeding groove 4 inside the connecting plate 3 connects the upper storage component and the metering tank 5. The storage component delivers the odor removal agent to the metering tank 5 by gravity or pressure. The outer wall of the metering tank 5 is rotatably connected to the tank bottom 7 by the hinge 6. The fixing plate 8 fixes the sliding plate 9. When the connecting plate 3 drives the metering tank 5 and the tank bottom 7 to slide out of the inner wall of the sliding plate 9, the tank bottom 7 rotates around the hinge 6 to open, so that the metered odor removal agent is accurately added to the landfill leachate. This structure plays the role of metered odor removal agent addition, maintaining the deodorization effect of the landfill leachate while avoiding waste of deodorizing agent.

[0025] Reference Figure 1 The storage assembly includes a column 10, the outer wall of the column 10 is fixedly connected to the outer wall of the U-shaped block 1, a fixing block 11 is fixedly connected to the outer wall of the column 10, a storage bin 12 is fixedly connected to the outer wall of the fixing block 11, and the upper surface of the connecting plate 3 is slidably connected to the lower surface of the storage bin 12.

[0026] Specifically, the column 10 is fixed to the outer wall of the U-shaped block 1 to provide support. The column 10 is fixed to the storage bin 12 by the fixing block 11. The storage bin 12 is used to store materials such as odor removers. The lower surface of the storage bin 12 is in contact with the connecting plate 3. When the outlet of the lower surface of the storage bin 12 is facing the feeding trough 4, the deodorant in the storage bin 12 flows into the metering tank 5 under the influence of gravity. When the outlet of the lower surface of the storage bin 12 slides out of the feeding trough 4, the connecting plate 3 will prevent the deodorant in the storage bin 12 from continuing to flow out.

[0027] Reference Figure 1 and Figure 3A water storage tank 13 is fixedly connected to the lower surface of the column 10. A cover plate 14 is fixedly connected to the upper surface of the water storage tank 13. A hinge 15 is fixedly connected to the upper surface of the cover plate 14. A cover plate 16 is fixedly connected to the outer wall of the hinge 15. The lower surface of the cover plate 16 is in contact with the upper surface of the water storage tank 13. A water outlet pipe 17 is fixedly connected inside the water storage tank 13. A valve 18 is fixedly installed inside the water outlet pipe 17.

[0028] Specifically, the water storage tank 13 not only connects and fixes the column 10, but also stores the leachate after preliminary filtration. The cover plate 14 is fixed to the upper surface of the water storage tank 13, providing initial protection. The hinge 15 connects the cover plate 14 and the cover plate 16, allowing the cover plate 16 to rotate and open around the hinge 15. When the cover plate 16 is open, it facilitates the quantitative addition of the deodorizing agent. When the lower surface of the cover plate 16 is in contact with the upper surface of the water storage tank 13, it seals the water storage tank 13, preventing liquid evaporation and impurities from entering. The outflow of liquid in the water storage tank 13 can be controlled by opening or closing the valve 18. When the leachate needs to react with the deodorizing agent, the valve 18 is closed. After the reaction is complete, the valve 18 is opened, and the leachate flows out of the water storage tank 13 through the outlet pipe 17. This structure can quantitatively control the leachate participating in the reaction, making the deodorization effect more stable.

[0029] Reference Figure 1 , Figure 3 and Figure 4 A second water outlet pipe 19 is fixedly connected inside the water storage tank 13. A second valve 20 is fixedly installed inside the second water outlet pipe 19. The other end of the second water outlet pipe 19 is fixedly connected to the lower interior of the filter barrel 21. An inlet pipe 22 is fixedly connected to the upper interior of the filter barrel 21. A baffle 23 is fixedly connected to the outer wall of the inlet pipe 22. The outer wall of the baffle 23 is fixedly connected to the inner wall of the filter barrel 21. A filter element 24 is fixedly connected to the outer wall of the baffle 23. The lower surface of the filter element 24 is fixedly connected to the inner wall of the filter barrel 21. Filter barrel 21 A bucket lid 25 is fixedly connected to the upper surface of the filter bucket 21. A water purification pipe 26 is fixedly connected inside the bucket lid 25. The lower surface of the water purification pipe 26 is fixedly connected to the inner wall of the baffle 23. A water pump 27 is fixedly connected to the other end of the water purification pipe 26. A water purification tank 28 is fixedly connected inside the water pump 27. The outer wall of the water purification tank 28 is in contact with the outer wall of the water storage tank 13. A check valve 31 is fixedly installed inside the water purification pipe 26. A drain pipe 29 is fixedly connected inside the filter bucket 21. A valve 30 is fixedly installed inside the drain pipe 29.

[0030] Specifically, the filter canister 21 serves to fix the inlet pipe 22. The leachate enters the filter canister 21 through the inlet pipe 22. The baffle 23 prevents backflow of the leachate, allowing it to pass through the filter element 24 for filtration. The filter element 24 removes substances with irritating odors from the leachate through adsorption or chemical reaction, reducing odor intensity. It also intercepts large particles and some large organic molecules in the leachate, achieving preliminary physical filtration, reducing microbial content and colloidal contamination, and minimizing odors and pollutants generated by microbial metabolic activity. The canister lid 25 provides a sealing and protective function for the filter canister 21. The purified water pipe 26... A check valve 31 is fixedly installed on the water pipe 26, which passes through the lid 25 and the baffle 23, to prevent liquid backflow. The water tank 28 stores clean water for cleaning the inner wall of the filter element 24. The water pump 27 pumps the clean water into the filter element 24 through the water pipe 26 to clean the residue on the inner wall of the filter element 24. After cleaning, the check valve 31 is opened to discharge the wastewater containing residue into the filter bucket 21 through the drain pipe 29. The above steps are repeated until the cleaning effect is achieved. This structure ensures the filtration effect of the filter element 24. The whole structure achieves the orderly operation of liquid from storage, filtration to purification storage and sewage discharge through the coordinated operation of various components, which helps to remove the odor of landfill leachate.

[0031] Working principle: When the device is needed, the pre-filtered leachate is discharged into the storage tank 13 through the outlet pipe 19. The cover plate 16 is opened, and the deodorant in the storage bin 12 can enter the metering tank 5 through the feed chute 4 directly below. At this time, the cylinder 2 is activated. The output end of the cylinder 2 pushes the connecting plate 3 to slide in the groove opened on the U-shaped block 1. The connecting plate 3 drives the metering tank 5 to move horizontally together. When the feed chute 4 is completely separated from the storage bin 12, the connecting plate 3 will stop the deodorant from flowing out. At this time, the bottom 7 of the metering tank 5 will slide out from the upper surface of the slide plate 9. At this time, the bottom 7 of the tank opens, and the deodorant in the metering tank 5 enters the leachate in the storage tank 13. Through this structure, the deodorant can be quantitatively added, which can maintain the deodorization effect of the leachate and save the cost of deodorant. Moreover, reasonable quantitative addition can prevent the excessive use of deodorant from causing new pollution.

[0032] When leachate enters the filter element 24 inside the filter canister 21 through the inlet pipe 22, odor sources in the leachate, such as microbial aggregates, humic colloids, and debris, are trapped by the filter element 24 and adhere to its inner wall. The filtered leachate then enters the storage tank 13 through the outlet pipe 19 for further deodorization. At this time, the inner wall of the filter element 24 needs to be cleaned. The water pump 27 is turned on, and the water pump 27 flushes the clean water in the clean water tank 28 into the inner wall of the filter element 24 through the clean water pipe 26 to clean the residue. Then, the check valve 31 is opened, and the wastewater containing the residue is discharged from the filter canister 21 through the drain pipe 29. The above steps are repeated until the cleaning effect is achieved. This structure can play a role in the initial filtration of leachate and cleaning of the filter element 24, thereby restoring the filtration capacity of the filter element 24 and extending its service life.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
