Description

Technical Field

[0001] The utility model relates to the technical field of leachate treatment devices, in particular to a high-concentration odor treatment device used in a leachate plant. Background Art

[0002] Leachate plants, when treating landfill or industrial waste, produce highly concentrated liquids. Because these liquids contain large amounts of organic and inorganic matter, anaerobic decomposition produces foul-smelling gases such as hydrogen sulfide, ammonia, and methane. These odors not only pollute the surrounding environment and impact residents' quality of life, but can also pose a threat to human health. Therefore, leachate plants must employ a variety of methods, including physical, chemical, and biological methods, to remove these odorous components, ensuring compliance with emission standards and minimizing environmental impact.

[0003] The current deodorization methods for leachate plants include "acid washing + alkaline washing" or "acid washing + alkaline washing + oxidation" and other treatment processes. However, the processing capacity of the current on-site deodorization treatment equipment is limited, and it is impossible to treat the odor of the leachate plant to a state of odorless emission. The odor from the exhaust gas outlet meets the emission standards but still has a noticeable odor, which significantly affects the surrounding park environment and the quality of life of residents.

[0024] The embodiment of the utility model provides a high-concentration odor treatment device for a leachate plant, which is used to solve the technical problem that the treatment capacity of existing on-site deodorization treatment devices is limited, thereby affecting the surrounding park environment and the quality of life of residents.

[0025] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0028] See also Figure 1 , the present application provides an embodiment of a high-concentration odor treatment device for a leachate plant, comprising: an odor conveying system and a garbage bin;

[0029] The leachate plant is connected to the odor conveying system through a high-concentration deodorization air duct; the odor conveying system is connected to the garbage bin; the odor conveying system includes two sets of high-concentration odor induced draft fans that serve as backup for each other.

[0030] Taking into account the limited processing capacity of the current on-site chemical deodorization device, the utility model adopts different treatment methods for low-concentration odor and high-concentration odor. The low-concentration odor is still treated by the on-site chemical deodorization device, while the high-concentration odor is introduced into the garbage bin for treatment to significantly reduce the exhaust gas emission concentration of the treatment plant, improve the park environment and the quality of life of surrounding residents, and add an odor conveying system to increase the conveying rate of high-concentration odor. At the same time, it can reduce the use of reagents in the on-site chemical deodorization device and save operating costs.

[0031] In order to ensure the safe and stable operation of the high-concentration odor treatment device, the odor conveying system uses two sets of high-concentration odor induced draft fans that serve as backup for each other to transport odor. A one-in-use and one-in-backup method is adopted. When one of the high-concentration odor induced draft fans fails, the other can be put into use immediately, thereby ensuring the continued safe operation of the device.

[0032] In a specific embodiment, the high-concentration odor induced draft fan is provided with an inlet air duct and an outlet air duct.

[0033] In a specific embodiment, an electric valve is provided at the inlet air duct of the high-concentration odor induced draft fan to facilitate the operation and control switching of the two sets of high-concentration odor induced draft fans; a manual valve is provided at the outlet air duct of the high-concentration odor induced draft fan to stabilize the pressure at the outlet of the high-concentration odor induced draft fan and avoid the failure of the electronic valve that makes it difficult for the equipment to continue operating.

[0034] In one specific embodiment, the outlet duct of a high-concentration odor induced draft fan is connected to a height of 26.5 meters inside the garbage bin, thereby directing high-concentration odors into the bin for incineration. Furthermore, by installing a high-concentration odor induced draft fan at the end of the garbage bin, the duct maintains a negative pressure, effectively preventing odor leakage during pipeline transportation.

[0035] In a specific embodiment, the odor conveying system is installed in the boiler room next to the garbage bin.

[0036] In a specific embodiment, a drain pipe is provided at a low position of the high-concentration deodorizing air duct. The drain pipe provided at a low position along the high-concentration deodorizing air duct can effectively prevent high-concentration odor from condensing into water and causing pipe blockage.

[0037] In one specific embodiment, due to the complex composition of high-concentration odor, which may contain flammable gases such as methane, operating a conventional blower in such a high-concentration odor environment could generate sparks and other explosion hazards. To ensure the safe operation of the odor conveying system, a variable-frequency explosion-proof and corrosion-resistant blower is used as the high-concentration odor induced draft fan. This variable-frequency explosion-proof and corrosion-resistant blower can also adjust its speed based on actual needs, thereby controlling the amount of high-concentration odor conveyed.

[0038] In a specific embodiment, the power, air volume and air pressure parameters of the high-concentration odor induced draft fan can be set to 15Kw, 4000m³ / h and 5000Pa respectively.

[0039] In a specific embodiment, in order to extend the life of the pipeline, the high-concentration deodorization air duct is lined with Q235-A plastic high-strength anti-corrosion material, and a DN400 pipeline is used to extract high-concentration odor in the leachate.

[0040] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
