Description

Technical Field

[0001] The invention relates to the field of garbage disposal, in particular to a water blocking and odor isolating device for a leachate collection pool. Background Art

[0002] Garbage disposal methods can generally be divided into several methods such as sanitary landfill, incineration, and composting. A landfill is a centralized garbage storage site that uses sanitary landfill. It is widely used in China because of its low cost and good hygiene. Garbage incineration power generation is a traditional method of garbage disposal. After the garbage is treated by incineration, the reduction effect is significant, land is saved, various pathogens can be eliminated, and toxic and harmful substances can be converted into harmless substances. The heat energy generated by garbage incineration can also be used for power generation. Therefore, garbage incineration has become one of the main methods of urban garbage disposal.

[0003] But whether it is sanitary landfill or incineration power generation, the garbage must first be dehydrated in the garbage pit. The leachate produced by garbage dehydration is collected in the leachate collection pool and then enters the leachate treatment station for treatment before entering the subsequent process. The leachate treatment station includes an anaerobic reaction pool, a digestion pool, a denitrification pool and a regulating pool. The leachate collection pool is mainly used for the collection and temporary storage of leachate. The size of the leachate collection pool is 50m*50m*6m. The traditional leachate collection pool is an open-air structure. On the one hand, the leachate in the leachate collection pool has a peculiar smell, which will pollute the ambient air and affect the health of the staff; on the other hand, rainwater falls directly into the leachate collection pool, which increases the content of leachate, which will undoubtedly increase the amount of leachate to be treated in the later stage, especially in southern cities, which increases costs and reduces the efficiency of leachate treatment. Summary of the invention

[0004] In view of the technical problem that the traditional open leachate collection pool is not odor-proof and rain-proof, the present invention provides a water-blocking and odor-isolating device for the leachate collection pool.

[0005] The technical solution adopted by the present invention is: a water-blocking and odor-isolating device for a leachate collection pool, comprising a leachate collection pool, wherein an air cushion matching the size of the leachate collection pool is arranged in the leachate collection pool, and the air cushion can float on the surface of the liquid in the leachate collection pool, and the air cushion comprises a bottom pad and side pads arranged around the bottom pad, the bottom pad is connected to the side pads, and an air inlet and an air outlet are arranged on the side pads. When in use, the air cushion is inflated through the air inlet to fill the air cushion, and the installation of the air cushion and the leachate collection pool can be completed. The present invention is cleverly designed, and the air cushion can float on the surface of the liquid in the leachate collection pool, and can change synchronously with the change of the liquid level, so that the air cushion can play the role of closing the leachate collection pool, and can prevent the odor in the leachate collection pool from escaping to pollute the ambient air and affect the health of the staff. The groove formed by the side pad and the bottom pad can also be used to collect rainwater, to prevent rainwater from falling directly into the leachate collection pool, thereby reducing the processing amount of leachate, effectively reducing the cost, and improving the processing efficiency.

[0006] Furthermore, the bottom pad is a slope, and a water reservoir is arranged on one side of the lower end of the slope. The water reservoir is used to temporarily store rainwater collected by the air cushion for later processing; at the same time, since the bottom pad is a slope, it is convenient for rainwater to flow naturally into the water reservoir.

[0007] Furthermore, the bottom pad is evenly provided with water guide grooves connected to the water reservoir. The water guide grooves can reinforce the bottom pad on the one hand, and also play a role of diversion on the other hand, so that rainwater can flow to the water reservoir through the water guide grooves for temporary storage.

[0008] Furthermore, the slope of the slope is 1° to 5°. If the slope is too large, the thickness of the base pad will increase, thereby reducing the volume of the air cushion to accommodate rainwater; if the slope is set too small, it will not divert the flow. Therefore, the preferred slope of the present invention is 1° to 5°.

[0009] Furthermore, the slope of the slope is 3°.

[0010] Furthermore, a water pump is provided in the water reservoir for pumping out the accumulated water in the water reservoir, and the whole process is highly automated.

[0011] Furthermore, a filter pad is vertically arranged in the water reservoir, and filter holes are evenly arranged on the filter pad. The filter pad divides the water reservoir into a filter pool and a clarification pool. The water pump is arranged in the clarification pool, and the filter pad is connected to the side pad. Rainwater falling on the air cushion will be accompanied by some large impurities such as branches and leaves, and branches. In order to prevent these large impurities from clogging the water pump, a filter pad is vertically arranged in the water reservoir to filter these impurities.

[0012] Furthermore, a top pad that can open and close the clarifier is provided on the top of the clarifier, and the top pad is connected to the side pads to prevent large impurities above the clarifier from falling into the clarifier, thereby sealing the top of the clarifier.

[0013] Furthermore, the bottom pad and the side pad are integrally formed to improve the stability of the connection between the two.

[0014] Furthermore, the bottom pad and the side pads are both made of rubber, which has the advantages of elasticity, wear resistance, cold resistance, non-deflating, aging resistance, and corrosion resistance, and is very suitable for use in leachate collection pools.

[0015] The beneficial effects of the present invention are:

[0016] 1. The air cushion of the present invention can float on the surface of the liquid in the leachate collection pool and can change synchronously with the change of the liquid level. Therefore, the air cushion can play the role of closing the leachate collection pool, which can prevent the odor in the leachate collection pool from escaping to pollute the ambient air and affect the health of the staff.

[0017] 2. The grooves formed by the side pads and the bottom pads of the present invention can also be used to collect rainwater to prevent rainwater from falling directly into the leachate collection pool, thereby reducing the amount of leachate to be processed, effectively reducing costs and improving processing efficiency.

[0018] 3. The water reservoir of the present invention is used to temporarily store rainwater collected by the air cushion for later processing; at the same time, since the bottom cushion is a slope, it is convenient for rainwater to flow naturally into the water reservoir.

[0019] 4. The filter pad of the present invention can filter out large impurities such as branches, leaves, and trunks, thereby preventing these large impurities from clogging the water pump. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Embodiment 1

[0030] Reference Figure 1 and Figure 2 The water-blocking and odor-isolating device for a leachate collection pool of the present invention comprises a leachate collection pool 1, wherein an air cushion 2 matching the size of the leachate collection pool is arranged in the leachate collection pool 1, and the air cushion 2 can float on the surface of the liquid in the leachate collection pool, and the air cushion 2 comprises a bottom pad 21 and side pads 22 arranged around the bottom pad, and the bottom pad 21 is connected to the side pads 22, and the side pads 22 are provided with an air inlet 220 and an air outlet 221. When in use, the air cushion is inflated through the air inlet to fill the air cushion, and the installation of the air cushion and the leachate collection pool can be completed. The present invention is cleverly designed, and the air cushion can float on the surface of the liquid in the leachate collection pool, and can change synchronously with the change of the liquid level, so that the air cushion can play a role in closing the leachate collection pool, and can prevent the odor in the leachate collection pool from escaping to pollute the ambient air and affect the health of the staff. The grooves formed by the side pads and the bottom pads can also be used to collect rainwater to prevent rainwater from falling directly into the leachate collection pool, thereby reducing the amount of leachate to be processed, effectively reducing costs and improving processing efficiency.

[0031] Reference Figure 2 The bottom pad 21 of this embodiment is a slope, and a water reservoir 3 is arranged on one side of the lower end of the slope. The water reservoir is used to temporarily store rainwater collected by the air cushion for later processing; at the same time, since the bottom pad is a slope, it is convenient for rainwater to flow naturally to the water reservoir.

[0032] Reference Figure 2In this embodiment, water guide grooves 210 connected to the water reservoir 3 are evenly arranged on the bottom pad 21. The water guide grooves can reinforce the bottom pad on the one hand, and also play a role of diversion, so that rainwater can flow to the water reservoir through the water guide grooves for temporary storage.

[0033] In this embodiment, if the slope is too steep, the thickness of the base pad will increase, thereby reducing the volume of the air cushion to accommodate rainwater; if the slope is set too small, it will not divert the flow. Therefore, the preferred slope of the present invention is 3°.

[0034] In this embodiment, a water pump (not shown in the figure) is arranged in the water reservoir 3 for pumping out the accumulated water in the water reservoir, and the whole process has a high degree of automation.

[0035] In this embodiment, the bottom pad 21 and the side pad 22 are integrally formed to improve the stability of the connection between the two.

[0036] In order to avoid water in the leachate collection pool, the inventor of this application has previously taken other measures: installing a canopy on the top of the leachate collection pool. The size of the leachate collection pool is 50m*50m*6m. Due to the large span and high height of the leachate collection pool, it is necessary to set several support columns for supporting the canopy in the leachate collection pool. However, the leachate is extremely corrosive and will corrode the support columns, causing the canopy to collapse in less than a year of use. Moreover, the canopy can only play a simple water-proof effect, and cannot play a role in isolating odors.

[0037] Embodiment 2

[0038] Since the rainwater falling on the air cushion will be accompanied by some large impurities such as branches and trunks, in order to prevent these large impurities from clogging the water pump, a filter pad is vertically installed in the water reservoir to filter these impurities. Figure 2 On the basis of the first embodiment, in this embodiment, a filter pad 4 is vertically arranged in the water reservoir 3, and filter holes 41 are evenly arranged on the filter pad 4. The filter pad 4 divides the water reservoir 3 into a filter tank 31 and a clarification tank 32. The water pump is arranged in the clarification tank, and the filter pad 4 is connected with the side pad 22.

[0039] Embodiment 3

[0040] On the basis of the second embodiment, this embodiment is provided with a top pad (not shown in the figure) on the top of the clarifier tank that can open and close the clarifier tank. The top pad is connected with the side pad to prevent large impurities above the clarifier tank from falling into the clarifier tank, and plays a sealing role on the top of the clarifier tank. The top pad is connected to the clarifier tank by Velcro, which can realize the rapid opening and closing of the clarifier tank.

[0041] The bottom pad 21, side pad 22, filter pad and top pad of this embodiment are all made of rubber. Rubber has the advantages of elasticity, wear resistance, cold resistance, non-deflating, anti-aging, and corrosion resistance, and is very suitable for use in leachate collection pools.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
