Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a circulating cooling system for a small-scale underground integrated waste leachate treatment equipment. 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 heat during operation, making it difficult to maintain the equipment's temperature within a suitable range. For biochemical modules that utilize microorganisms to purify municipal solid waste leachate, excessively high temperatures reduce the treatment effect and efficiency of the microorganisms. Therefore, there is an urgent need to research and develop a circulating cooling system for a small-scale, integrated underground leachate treatment system to solve the aforementioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a circulating cooling system for a small-scale integrated underground landfill leachate treatment device. This circulating cooling system can realize heat exchange between the biochemical module and the treatment effect and efficiency of the leachate from municipal solid waste, thus avoiding excessively high temperatures.

[0006] To achieve the above objectives, the circulating cooling system of the small-scale integrated underground landfill leachate treatment equipment provided by this utility model has the following specific implementation scheme:

[0007] The circulating cooling system of the small-scale underground landfill leachate treatment integrated equipment includes a biochemical reaction chamber for carrying the circulating cooling system, a cooling circulation tower is provided on the top of the biochemical reaction chamber, a first pipe is connected to the circulation outlet at the bottom of the cooling circulation tower, the first pipe is connected to a circulating cooling pump, and a second pipe is connected to the outlet of the circulating cooling pump.

[0008] The biochemical reaction chamber is equipped with a circulating cooling pipe. The second pipe extends into the biochemical reaction chamber and connects to the circulating cooling pipe. The other end of the circulating cooling pipe is connected to a third pipe, which extends outside the biochemical reaction chamber and connects to the circulation inlet of the cooling circulation tower.

[0009] In some embodiments, the circulating cooling pipe is attached to the inner wall of the biochemical reaction chamber.

[0010] In some embodiments, tube grooves are fitted at both ends of the circulating cooling pipe, and the tube grooves are fixedly connected to the inner wall of the biochemical reaction chamber.

[0011] In some embodiments, a first connector is provided at one end of the circulating cooling pipe, the first connector being connected to the second pipe, and a second connector is provided at the other end of the circulating cooling pipe, the second connector being connected to the third pipe.

[0012] In some embodiments, the circulating cooling pipe comprises a plurality of integrally formed U-shaped pipes.

[0013] In some embodiments, a cooling fan is provided at the top of the cooling circulation tower, a circulation inlet of the cooling circulation tower is provided below the cooling fan, a cooling filter material is provided below the circulation inlet, and a circulation outlet is provided below the cooling filter material.

[0014] In some embodiments, a water distributor is provided inside the cooling circulation tower between the cooling fan and the cooling filter material, and the inlet of the water distributor is connected to the circulation inlet.

[0015] In some embodiments, the cooling filter material is provided with a plurality of cooling channels, each cooling channel having at least two bends.

[0016] In some embodiments, a circulation pump is provided on the third pipe to transport the liquid in the cooling circulation pipe to the cooling circulation tower.

[0017] Based on the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0018] 1. By installing a circulating cooling pipe inside the biochemical reaction chamber, one end of the circulating cooling pipe is connected to a second pipe, and the other end is connected to a third pipe. The second pipe is connected to a circulating cooling pump, and the circulating cooling pump is connected to the circulation outlet of the cooling circulation tower through a first pipe and the circulation inlet of the cooling circulation tower through a third pipe. This allows the cooled liquid from the cooling circulation tower to be sent into the circulating cooling pipe through the first and second pipes to exchange heat and cool down the biochemical reaction chamber. The heated liquid returns to the cooling circulation tower through the third pipe to cool down again, thus achieving the purpose of circulating cooling.

[0019] 2. By attaching the circulating cooling pipes tightly to the inner wall of the biochemical reaction chamber, cooling efficiency is improved and energy waste is reduced.

[0020] 3. By sleeved with pipe grooves at both ends of the circulating cooling pipe, and the pipe grooves being fixedly connected to the inner wall of the biochemical reaction chamber, the installation stability and usage stability of the circulating cooling pipe in the biochemical reaction chamber are improved.

[0021] 4. By using the first connector to connect the second pipe and the circulating cooling pipe, and by using the second connector to connect the third pipe and the circulating cooling pipe, the disassembly of the circulating cooling pipe is made easier, facilitating subsequent cleaning and maintenance.

[0022] 5. By setting the circulating cooling pipe to include several integrally formed U-shaped pipes, the cooling range and cooling time between the circulating cooling pipe and the chemical reaction chamber are increased, thereby improving the cooling effect.

[0023] 6. By installing a cooling fan inside the cooling circulation tower, the cooling fan sends cold air from outside into the cooling circulation tower to work with the cooling filter material to cool the heat exchange liquid inside the cooling circulation tower.

[0024] 7. By installing a water distributor between the cooling fan and the cooling filter media, the heat exchange liquid can be evenly delivered to the cooling filter media, thereby improving the cooling effect and efficiency.

[0025] 8. By setting several cooling channels inside the cooling filter material, each cooling channel has at least two bends, the flow time of the liquid inside the cooling filter material is extended, thereby improving the cooling effect.

[0026] 9. By installing a circulation pump on the third pipeline, the heat exchange liquid can be transferred from the cooling circulation pipe into the cooling circulation tower. Attached Figure Description
