Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a negative pressure deodorization device for an integrated treatment equipment for leachate from municipal solid waste. Background Technology

[0002] Municipal solid waste leachate refers to a dark brown, foul-smelling liquid containing high concentrations of organic pollutants, heavy metals, pathogens, and toxic substances, produced during the dumping or landfilling of waste due to compaction, fermentation, and rainwater leaching. Its composition is complex, including ammonia nitrogen, COD (chemical oxygen demand), BOD (biochemical oxygen demand), salts, and various carcinogens (such as polycyclic aromatic hydrocarbons).

[0003] If leachate is released directly into the environment without treatment, it will severely pollute soil and groundwater, leading to eutrophication and damaging ecosystems. Heavy metals accumulate through the food chain, threatening human health and causing diseases such as cancer and liver and kidney damage. Pathogenic microorganisms in leachate may also spread diseases. Therefore, leachate is classified as a high-risk pollutant and must be strictly collected and treated using physical, chemical, and biological processes to meet standards before being discharged.

[0004] Traditional municipal solid waste leachate treatment equipment generates a large amount of odor during operation. If left untreated, this odor is directly discharged, polluting the surrounding air. Therefore, there is an urgent need to research and develop a negative pressure deodorization device for integrated municipal solid waste leachate treatment equipment to solve the aforementioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a negative pressure deodorization device for an integrated treatment equipment for municipal solid waste leachate, which can collect and purify the odor generated during the operation of the integrated treatment equipment for municipal solid waste leachate.

[0006] To achieve the above objectives, this utility model provides a negative pressure deodorization device for an integrated treatment system for municipal solid waste leachate, the specific implementation of which is as follows:

[0007] A negative pressure deodorization device for an integrated treatment equipment for municipal solid waste leachate includes a negative pressure deodorization component. The inlet of the negative pressure deodorization component is connected to an odor collection pipe, and the outlet of the negative pressure deodorization component is connected to an emission pipe for discharging compliant gases.

[0008] The odor collection pipe has several odor collection ports. The reaction tank, sedimentation tank, biochemical reaction chamber and cooling chamber of the integrated treatment equipment for municipal solid waste leachate are all equipped with the odor collection ports or are connected to the odor collection ports through pipes.

[0009] The negative pressure deodorization component is equipped with a negative pressure fan and an odor adsorption unit. The exhaust port of the negative pressure fan corresponds to the outlet of the odor collection pipe, and the odor adsorption unit is located between the negative pressure fan and the outlet of the odor collection pipe.

[0010] In some embodiments, the negative pressure deodorization component includes a housing, in which a negative pressure fan and an odor adsorption unit are provided, and the odor collection pipe and the discharge pipe are both connected to the interior of the housing.

[0011] In some embodiments, the odor adsorption unit includes a PP cotton filter adsorption layer and a honeycomb activated carbon filter adsorption layer. The PP cotton filter adsorption layer and the honeycomb activated carbon filter adsorption layer are arranged sequentially along the outlet of the odor collection pipe to the negative pressure fan, and both the PP cotton filter adsorption layer and the honeycomb activated carbon filter adsorption layer are detachably connected to the housing.

[0012] In some embodiments, an airflow sensor is provided inside the housing, located between the PP cotton filter adsorption layer and the outlet of the odor collection pipe, to detect the airflow of odor entering the odor adsorption section. The airflow sensor is electrically connected to the controller of the negative pressure fan.

[0013] In some embodiments, the feature is that each of the odor collection ports is provided with a plurality of odor sensors for detecting the odor concentration near the odor collection port, and each of the odor sensors is electrically connected to the controller of the negative pressure fan.

[0014] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] 1. By connecting the odor collection pipe to the inlet of the negative pressure deodorization component and the discharge pipe to the outlet, and installing a negative pressure fan and an odor adsorption unit inside, the negative pressure fan operates to draw in odors from the reaction tank, sedimentation tank, biochemical reaction chamber, and cooling chamber. The odors are drawn into the odor collection pipe through the odor collection port and enter the negative pressure deodorization component. After being adsorbed and purified by the odor adsorption unit, the odors are discharged through the discharge pipe in compliance with standards. This achieves deep coupling between the deodorization device and the integrated treatment equipment for municipal solid waste leachate, as well as multi-stage synergistic deodorization, and has the technical advantage of high-efficiency deodorization.

[0016] 2. By placing the negative pressure fan and odor adsorption unit of the negative pressure deodorization component inside the box, the sealing performance of odor treatment is improved, and odor leakage is prevented.

[0017] 3. By setting the odor adsorption section to adsorb odors using PP cotton filter media and honeycomb activated carbon filter media, regeneration after use is simple. Even if regeneration is not possible, it can be centrally transported for treatment without causing secondary pollution.

[0018] 4. By installing an air volume sensor inside the chamber, the air volume of odor entering the odor adsorption section is detected. The suction power of the negative pressure fan is adjusted according to the air volume of odor entering the odor adsorption section to avoid environmental pollution caused by the overflow of odor due to large air volume.

[0019] 5. By installing an odor sensor on the odor collection port, the odor concentration near the odor collection port can be detected, allowing for more accurate capture of odor fluctuations. Combined with the controller of the negative pressure fan, this enables precise and automatic odor extraction. Attached Figure Description

[0025] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0026] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0027] like Figure 1 As shown, the negative pressure deodorization device of the integrated treatment equipment for municipal solid waste leachate provided in this embodiment includes a negative pressure deodorization component 10. The inlet of the negative pressure deodorization component 10 is connected to an odor collection pipe 20, and the outlet of the negative pressure deodorization component 10 is connected to an emission pipe 30 for discharging compliant gases.

[0028] The odor collection pipe 20 has several odor collection ports 201. The reaction tank, sedimentation tank, biochemical reaction chamber and cooling chamber of the integrated treatment equipment for leachate of domestic waste are all equipped with the odor collection ports 201 or the odor collection ports 201 are connected through pipes.

[0029] The negative pressure deodorization component 10 is provided with a negative pressure fan 102 and an odor adsorption unit 103. The exhaust port of the negative pressure fan 102 corresponds to the outlet of the odor collection pipe 20, and the odor adsorption unit 103 is located between the negative pressure fan 102 and the outlet of the odor collection pipe 20.

[0030] In some embodiments, the negative pressure deodorization component 10 includes a housing 101, in which the negative pressure fan 102 and the odor adsorption unit 103 are provided, and the odor collection pipe 20 and the discharge pipe 30 are both connected to the interior of the housing 101.

[0031] In some embodiments, the odor adsorption unit 103 includes a PP cotton filter adsorption layer 1031 and a honeycomb activated carbon filter adsorption layer 1032. The PP cotton filter adsorption layer 1031 and the honeycomb activated carbon filter adsorption layer 1032 are arranged sequentially along the direction from the outlet of the odor collection pipe 20 to the negative pressure fan 102, and both the PP cotton filter adsorption layer 1031 and the honeycomb activated carbon filter adsorption layer 1032 are detachably connected to the housing 101.

[0032] In this embodiment, the PP cotton filter adsorption layer 1031 and the honeycomb activated carbon filter adsorption layer 1032 are detachably connected to the housing 101. This can be achieved by directly inserting the PP cotton filter adsorption layer 1031 and the honeycomb activated carbon filter adsorption layer 1032 into the housing 101 to fill it, or by using a frame structure that matches the housing 101 to fix them inside the housing 101. The key is to ensure that they can be installed inside the housing 101 and removed when needed for replacement.

[0033] In some embodiments, an airflow sensor is provided inside the housing 101, located between the PP cotton filter adsorption layer 1031 and the outlet of the odor collection pipe 20, to detect the airflow of odor entering the odor adsorption section 103. The airflow sensor is electrically connected to the controller of the negative pressure fan 102.

[0034] In some embodiments, the odor collection port 201 is provided with a plurality of odor sensors to detect the odor concentration near the odor collection port 201, and each odor sensor is electrically connected to the controller of the negative pressure fan 102.

[0035] The controller described in this embodiment uses a control cabinet from the prior art, which is sufficient as long as it can receive the detection signals from the air volume sensor and the odor sensor and control the operation and power of the negative pressure fan 102.

[0036] Understandably, control valves, as used in the prior art, can be installed on the emission pipe 30 and the odor collection pipe 20, and their opening and closing can be controlled by the electrical connection of the controller to achieve the switching of the open or closed state of the emission pipe 30 and the odor collection pipe 20 with the housing 101.

[0037] The negative pressure deodorization device of the integrated treatment equipment for municipal solid waste leachate provided in this embodiment, compared with the prior art, connects the inlet of the negative pressure deodorization component 10 to the odor collection pipe 20 and the outlet to the discharge pipe 30. It is equipped with a negative pressure fan 102 and an odor adsorption unit 103. When in use, the negative pressure fan 102 operates to draw air. The odor located in the reaction tank, sedimentation tank, biochemical reaction chamber and cooling chamber is drawn into the odor collection pipe 20 by the odor collection port 201 and enters the negative pressure deodorization component 10. After being adsorbed and purified by the odor adsorption unit 103, it is discharged from the discharge pipe 30 in compliance with the standards. This realizes the deep coupling of the deodorization device and the integrated treatment equipment for municipal solid waste leachate and multi-stage synergistic deodorization, which has the technical advantage of high-efficiency deodorization.
