Description

Technical Field

[0001] The invention relates to the technical field of urban garbage treatment, in particular to a rotary stirring absorption device. Background Art

[0002] Sanitary landfill is a common method of waste disposal. Landfills are centralized garbage storage sites that utilize sanitary landfilling. They are widely used in China due to their low cost and high sanitation. The pile of garbage formed by landfilling is called a landfill. As the amount of domestic waste continues to increase, the height of the landfill is also increasing. At this time, the garbage itself contains water, endogenous water generated by the decomposition of the garbage, and liquid formed by external moisture (such as atmospheric precipitation). Many garbage carry liquids. After a certain period of time, these liquids seep to the bottom of the landfill, forming leachate and some gases.

[0003] Application number 201410611338.0, a multi-layer leachate recharge network and gas-liquid exchange system for a landfill, only has a liquid absorption device, not a combined liquid and gas absorption device.

[0019] Example 1

[0020] like Figure 1 、 2, 3, 4, 5, a domestic waste landfill, comprising a covering layer 1, a support recovery system, an impermeable layer 3, and a landfill layer; the support recovery system comprises a permeate recovery system, a gas collection system, a control center 7 and a plurality of support collection piles 4; the permeate recovery system comprises a water pump 10, and the water pump 10 is connected to a permeate collection tank 12 through a permeate collection pipe 8; the gas collection system comprises an air pump 13, and the air pump 13 is connected to a gas collection part 14 through a gas collection pipe 9; the permeate recovery system is connected to the support collection pile 4 through the permeate collection pipe 8; the gas collection system is connected to the support collection pile 4 through the gas collection pipe 9; the support collection pile 4 comprises a pipe body 15, and the lower end of the pipe body 15 is connected to the foundation pile 16; the impermeable layer 3 is at the bottom of the landfill; a rotating stirring absorption device 17 is installed on the outside of the pipe body 15. An extension portion 18 is fixed to the top of the tube body 15, and a sealing portion 21 is fixed to the upper end of the support collection pile 4. The lower part of the tube body 15 is provided with a permeate collection port 19 and a gas collection port 20 located above the permeate collection port 19; the permeate collection tank 12 and the tube body include a liquid level detection device 39; the multiple tube bodies 15 are spliced together in sequence from bottom to top by bolts.

[0021] The covering layer 1 includes a permeate recharge network pipe 23, below which a nozzle 24 is installed; the permeate recharge network pipe 23 is connected to the permeate collection tank 12 via a pipe. A valve 41 is provided at the connection between the permeate recharge network pipe 23 and the permeate collection pipe. The gas collection part 14 is provided with a gas separation device and a gas storage tank. The permeate collection tank 12 is provided with a liquid level limiting device and a permeate collection valve. The permeate collection pipe 9 and the gas collection pipe 9 are located above the anti-seepage layer 3 and are provided with a pressure-bearing pipe on the outside. The absorption part 22 includes a filter structure 25, which is connected to the permeate storage part 27 via a collection branch pipe 26; the permeate storage part 27 is connected to the extension part 18 via a drainage pipe. The filter structure 2 includes a screen layer 28 and a porous ceramic part 29. The porous ceramic 29 is internally connected to the collection branch pipe 2; the screen layer 28 and the porous ceramic part 29 are provided with a spacer layer. The two filtering structures are spherical structures or spherical or columnar structures; the permeate storage part 2 is filled with absorbent fabric.

[0022] The landfill is leveled and compacted, and pile construction is carried out according to the designed workstations to install support and collection piles 4. An impermeable layer 3 is laid, and various system components are installed on top of the impermeable layer 3. The sealing portion 21 is installed on the base of the support and collection pile pipe body, and the landfill is then landfilled and compacted until the sealing portion 21 is covered.

[0023] First, the gas control valve 40 installed on the gas collection pipe 9 is opened. The control center controls the gas pump to pump gas from the interior of the support collection pile 4 to the gas collection part 14, causing the interior of the support collection pile 4 to be in a negative pressure state. Under the influence of external pressure and the negative pressure inside the support collection pile 4, the permeate and decomposition gas inside the garbage accumulation layer are filtered through the gas absorption part 22 and enter the collection pile pipe 4. The gas is discharged through the gas collection system and then enters the gas collection part 14 through the gas collection pipe 9. The gas collection part is equipped with a gas separation device 30 and a gas storage tank 31, and the gas is stored in the gas storage tank 31. The permeate enters the permeate collection tank 12 through the permeate collection pipe 8. At this time, the valve 41 is in the closed state.

[0024] The mesh layer 28 and the porous ceramic portion 29 are separated by a spacer. One function is to filter the liquid, while the other slows down the liquid flow rate. Furthermore, the permeate reservoir 27 is filled with absorbent fabric, which retains the liquid and creates a path for gas to pass through, limiting gas entry into the tube body 15. The spherical or columnar structure of the 25 increases the contact area with the waste.

[0025] At the same time, the control center is a PLC controller, which activates the rotary stirring absorption device 17. The rotary stirring absorption device 17 drives the rotary stirring cover 35 to rotate at high speed through the rotating shaft 38. The stirring blades 37 will crush the surrounding garbage, easily releasing the permeate and gas contained therein. Moreover, the filtering function of the rotating drum 36 makes the gas and liquid easily absorbed by the absorption part 22. Moreover, the rotary stirring absorption device 1 is not located on the same horizontal line, which can better cut the garbage distributed around the support collection pile; at the same time, the rotating rotating drum 36 will promote the formation of local air circulation, accelerate air flow, and enable the garbage to fully contact with oxygen. In addition, the high-speed rotating gears will reduce the density of the entire garbage pile, which can reduce the overall temperature of the garbage pile.

[0026] The control center 7 controls the air pump 13 to pump gas from the interior of the support collection pile 4 to the gas collection part 14, causing the interior of the support collection pile 4 to be in a negative pressure state. Under the action of the external pressure and the negative pressure inside the support collection pile 4, the permeate and decomposition gas inside the garbage accumulation layer are filtered through the gas absorption part 22 and enter the interior of the collection pile pipe 4. The gas enters the gas collection part 14 through the gas collection pipe 9. The gas collection part 14 is equipped with a gas separation device 30 and a gas storage tank 31, and the gas is stored in the gas storage tank 31. The permeate enters the permeate collection tank 12 through the permeate collection pipe 9. At this time, the gas control valve 40 is in the open state.

[0027] The steps of gas loosening mode are as follows:

[0028] The control center 7 controls the air pump 13 to pump gas from the gas collection unit 14 into the support and collection pile 4, closing the permeate collection valve 32 inside the support and collection pile 4. This creates a high pressure inside the support and collection pile 4. The gas passes through the gas collection unit and into the waste accumulation layer, where it cleans the filter structure 25 and loosens the waste accumulation layer. At this time, the gas control valve 40 is open.

[0029] The pressure-bearing pipe is a steel pipe, and the absorbent fabric is a highly water-absorbent fiber.

[0030] Example 2 differs from Example 1 in that, based on Example 1, the control center controls water pump 10 to pump liquid from permeate collection tank 12 to permeate recharge network pipe 23. A sprinkler 24 is installed below to wet the garbage layer and cool it. At this time, permeate collection valve 32, gas control valve 40, and valve 41 are closed.

[0031] When the liquid level detection device 39 in the permeate collection tank 12 detects that the permeate has reached a safe liquid level, the permeate collection valve 32 is closed. When the liquid level detection device 39 in the tube body 15 detects that the liquid level has reached a safe liquid level, the gas control valve 40 is closed.

[0032] Embodiment 2 is the best embodiment.

[0033] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
