A deep treatment device for leachate from a waste incineration plant with zero concentrate

Abstract

This invention discloses a zero-concentration leachate deep treatment device for waste incineration plants, comprising a pretreatment mechanism, a deep treatment mechanism, and an intelligent controller. The pretreatment mechanism is used for the initial treatment of leachate. A drive motor drives a connecting cylinder to rotate, which in turn drives a third bevel gear and a support plate. When the support plate rotates, it drives two stirring rods to rotate. Since the first bevel gear meshes with the second and third bevel gears respectively, the rotation of the third bevel gear drives the first and second bevel gears to rotate, thereby driving the sleeve column and the double-groove pulley. Since the upper and lower inner walls of the double-groove pulley and the middle inner wall of the two single-groove pulleys are all fitted with transmission belts, the double-groove pulley drives the two single-groove pulleys to rotate through the two transmission belts, thereby driving the two stirring rods to rotate. This allows the two stirring rods to fully stir the leachate inside the filter cylinder, improving the stirring efficiency.

Description

Technical Field

[0001] This invention belongs to the technical field of leachate treatment in waste incineration plants, specifically relating to a deep treatment device for leachate from waste incineration plants with zero concentrate. Background Technology

[0002] Currently, leachate from domestic municipal solid waste incineration plants is mostly treated using a process of: pretreatment → advanced treatment → nanofiltration → reverse osmosis. The permeate is reused within the plant. The nanofiltration and reverse osmosis concentrates are mixed and then enter a concentrate reduction system for further concentration and volume reduction. The compliant permeate is then mixed with the reverse osmosis permeate and reused. The concentrate is used for fly ash pulping or re-injection into the incinerator.

[0003] Existing pretreatment methods for treating leachate from waste incineration plants require stirring, filtering, and heating to produce a preliminary concentrate. However, the leachate often contains unburned waste and sludge. During stirring, the filter pores of the filter cylinder can easily become clogged with these substances, reducing the filtration efficiency. Furthermore, unburned waste and sludge can adhere to the inner wall of the filter cylinder, making cleaning difficult for workers. Summary of the Invention

[0004] The purpose of this invention is to provide a deep treatment device for leachate from a waste incineration plant with zero concentrate, in order to solve the problems mentioned in the background art, such as the filter holes of the filter cylinder being easily clogged by incompletely burned waste and mud, reducing the filtration effect of the filter cylinder, and the incompletely burned waste and mud adhering to the inner wall of the filter cylinder, which is not conducive to the cleaning work of the staff.

[0014] Compared with the prior art, the present invention provides a deep treatment device for leachate from waste incineration plants with zero concentrate, which has the following beneficial effects:

[0015] 1. This invention drives the connecting cylinder to rotate via a drive motor, which in turn drives the third bevel gear and the support plate. When the support plate rotates, it drives the two stirring rods to rotate. Since the first bevel gear meshes with the second and third bevel gears respectively, when the third bevel gear rotates, it drives the first and second bevel gears to rotate, thereby driving the sleeve column and the double-groove pulley. Since the upper and lower inner walls of the double-groove pulley and the middle inner wall of the two single-groove pulleys are all fitted with transmission belts, the double-groove pulley drives the two single-groove pulleys to rotate through the two transmission belts, thereby driving the two stirring rods to rotate. This allows the two stirring rods to fully stir the leachate inside the filter cylinder, improving stirring efficiency and stirring effect.

[0016] 2. During the rotation of the two stirring rods, the invention also drives the two incomplete gears to rotate. When the multiple teeth of the incomplete gears mesh with the multiple tooth grooves, it drives the two sliding rods to move towards the connecting cylinder on the two fixed frames and compresses the two springs. When the multiple teeth of the incomplete gears separate from the multiple tooth grooves, the extension of the two springs causes them to move towards the filter cylinder, so that the striking column can strike the inner wall of the filter cylinder. This prevents the filter holes of the filter cylinder from being blocked by unburned garbage and mud, improves the filtration effect of the filter cylinder, and also prevents the inner wall of the filter cylinder from being stuck with medicine, garbage and mud, making it convenient for workers to clean.

[0028] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the stirring and striking mechanism includes a connecting cylinder 38, a drive assembly, a stirring assembly, a striking assembly, and a heating column 20. The heating column 20 is installed at the bottom of the filter cylinder 17. A stirring assembly for stirring is rotatably connected to the upper outer wall of the heating column 20.

Spring 52 is sleeved on the outer wall of sliding rod 51 near filter cylinder 17, and both ends of spring 52 are fixedly connected to fixing frame 48 and anti-detachment plate 49 respectively. A striking column 50 is fixedly connected to one end of the sliding rod 51 near the filter cylinder 17. A connecting cylinder 38 is fixedly connected to the middle of the upper end of the stirring assembly. A square groove 46 matching the square column 37 is opened in the middle of the upper end of the connecting cylinder 38, and the square column 37 extends into the interior of the square groove 46. A driving assembly is installed on the lower outer wall of the connecting cylinder 38. The driving assembly drives the stirring assembly and the striking assembly to complete the stirring and striking work respectively. The driving assembly includes a U-shaped fixed cover 39, a first bevel gear 40, a transmission belt 41, a double-groove pulley 42, a sleeve column 43, a second bevel gear 44, a third bevel gear 45, and a single-groove pulley 47. The two single-groove pulleys 47 are sleeved on the upper side of the two stirring rods 19. The sleeve column 43 is rotatably sleeved on the lower outer side of the connecting cylinder 38. On the wall, a second bevel gear 44 is fixedly connected to the upper end of the sleeve 43, and the second bevel gear 44 is rotatably sleeved on the lower outer wall of the connecting cylinder 38. A double-groove pulley 42 is fixedly connected to the lower end of the sleeve 43, and the double-groove pulley 42 is rotatably sleeved on the lower outer wall of the connecting cylinder 38. A transmission belt 41 is sleeved on the upper and lower inner walls of the double-groove pulley 42 and the middle inner wall of the two single-groove pulleys 47. The double-groove pulley 42 drives the two single-groove pulleys 47 to rotate through the two transmission belts 41.

The U-shaped fixing cover 39 is fixedly connected to the lower surface of the sealing top plate 3.

A first bevel gear 40 is rotatably connected to one inner wall of the U-shaped fixing cover 39, and the first bevel gear 40 meshes with both the second bevel gear 44 and the third bevel gear 45. Through the stirring and striking mechanism, the stirring work can be completed more effectively, and the inner wall of the filter cylinder 17 can also be struck more effectively, thereby preventing the adhesion of medicine, waste, and dry substances to the inner wall of the filter cylinder 17.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the spray dosing assembly includes a deep dosing connection pipe 8 and multiple spray pipes 21. The rear end of the deep dosing connection pipe 8 is connected to multiple spray pipes 21 extending into the reaction space. Through the spray dosing assembly, the spray dosing work can be completed, so that the leachate from the initial treatment inside the reaction space can complete the deep reaction work.

[0030] like Figure 3 As shown, the two electrolysis blocks 22 are the anode block and the cathode block, respectively. Through the two electrolysis blocks 22, the leachate that has been initially treated can be electrolyzed.

[0031] In order to achieve intelligent control, the intelligent controller 15 is electrically connected to the drive motor 1, the first solenoid valve 7, the second solenoid valve 11, the heating column 20, the two electrolytic blocks 22, the first water pump 25, the second water pump 33, the air purifier 35 and the exhaust fan 36 via wires. Intelligent control can be achieved through the intelligent controller 15.

[0032] The working principle and usage process of this invention: Before use, the staff first installs the entire device at the designated location in the waste incineration plant. Then, the staff connects the intelligent controller 15 to the external power supply. Subsequently, the staff connects the liquid feed pipe 2, the dosing pipe 14, the deep dosing connection pipe 8, the gas discharge pipe 10, and the dosing pipe 14 to the leachate conveying pipe, the pretreatment agent conveying pipe, the deep treatment agent conveying pipe, the external exhaust pipe, and the external drainage pipe, respectively.

[0033] When in use, the staff first opens the valves of the leachate delivery pipe and the pretreatment agent delivery pipe. The leachate and pretreatment agent will then enter the interior of the filter cylinder 17 through the liquid inlet pipe 2 and the dosing pipe 14, respectively. Then, the staff operates the intelligent controller 15, which will control the drive motor 1 to work.

[0034] When the drive motor 1 is activated, it drives the connecting cylinder 38 to rotate. This rotation of the connecting cylinder 38 drives the third bevel gear 45 and the support plate 18. When the support plate 18 rotates, it drives the two stirring rods 19 to rotate. Since the first bevel gear 40 meshes with the second bevel gear 44 and the third bevel gear 45 respectively, the rotation of the third bevel gear 45 drives the first bevel gear 40 and the second bevel gear 44 to rotate, thereby driving the sleeve column 43 and the double-groove pulley 42. Because the upper and lower inner walls of the double-groove pulley 42 and the middle inner walls of the two single-groove pulleys 47 are all fitted with transmission belts 41, the double-groove pulley 42 drives the two single-groove pulleys 47 to rotate via the two transmission belts 41, thus causing the two stirring rods 19 to rotate. The stirring rod 19 can fully stir the leachate inside the filter cylinder. At the same time, during the rotation of the two stirring rods 19, the two incomplete gears 53 will also rotate. When the multiple teeth of the incomplete gears 53 mesh with the multiple tooth grooves 54, the two sliding rods 51 will move on the two fixed frames 48 toward the connecting cylinder 38 and compress the two springs 52. When the multiple teeth of the incomplete gears 53 separate from the multiple tooth grooves 54, the extension of the two springs 52 will cause them to move toward the filter cylinder, so that the striking column 50 can strike the inner wall of the filter cylinder. This prevents the filter holes of the filter cylinder from being blocked by unburned garbage and soil, improves the filtration effect of the filter cylinder, and also prevents the inner wall of the filter cylinder from being stuck with chemicals, garbage and soil.

[0035] During the entire stirring process, the heating column 20 heats the leachate, causing it to form a pre-concentrated liquid and the gas generated by heating. The liquid is then filtered through the filter cylinder 17 and the filter cotton sleeve 16, allowing the pre-concentrated liquid to flow to the bottom of the pretreatment tank 4.

[0036] Subsequently, the staff will operate the intelligent controller 15, which will then control the first solenoid valve 7 and the two electrolytic blocks 22 to work.

[0037] When the first solenoid valve 7 and the second solenoid valve 11 are activated, the initially concentrated liquid flows into the reaction space of the processing chamber 6 through the first solenoid valve 7 and the discharge pipe 5. At this time, the operator opens the valve of the deep treatment agent delivery pipe, and the deep treatment agent enters the interior of multiple spray pipes 21 through the deep dosing connection pipe 8. The deep treatment agent is then sprayed through the multiple spray pipes 21. Simultaneously, the two electrolytic blocks 22 can electrolyze the initially concentrated liquid and the deep treatment agent, thereby enabling the initially concentrated liquid and the deep treatment agent to fully react and produce gas. After the deep reaction time is reached, the operator operates the intelligent controller 15, which then activates the second solenoid valve 11, the first water pump 25, the air purifier 35, and the exhaust fan 36.

[0038] When the exhaust fan 36 is working, it will input the gas inside the pretreatment box 4 and the gas inside the reaction space of the treatment box 6 into the air purifier 35 through the multi-port gas delivery pipe 9. When the air purifier 35 is working, it will purify the gas. After the purification work is completed, the gas will be discharged through the connecting gas pipe 34, the working second solenoid valve 11, the gas discharge pipe 10 and the external exhaust pipe.

[0039] When the first water pump 25 is working, the liquid undergoing deep reaction can be input into the anaerobic treatment space of the treatment chamber 6 through the first filter connection pipe 23 and the second filter connection pipe 26, and the anaerobic treatment work can be completed inside the anaerobic treatment space.

[0040] Once the designated anaerobic working time is reached, the staff operates the intelligent controller 15, which activates the second water pump 33. At this time, the second water pump 33 transports the anaerobic liquid to the sedimentation space of the treatment chamber 6 through two third filter connection pipes 30, where sedimentation is completed. Simultaneously, adsorption is completed through the stepped graphene filter plate 31, ensuring that the liquid flowing to the dosing pipe 14 is clean. The clean liquid can then be discharged through the dosing pipe 14 and the external drain pipe.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
