Waste incineration is an old traditional method of dealing with waste.

[0029] like Figure 1 As shown, this embodiment provides a cooling water calling device for waste incineration treatment, including a flue gas cooler 1 and a plurality of condensers 2 connected to the incinerator, the water inlet end of the flue gas cooler 1 is connected to a plurality of first cooling water pumps 12 through a first water inlet pipe 11, and the water inlet end of each of the condensers 2 is connected to a second cooling water pump 22 through a second water inlet pipe 21, the first cooling water pump 12 and the second cooling water pump 22 are both arranged inside a water collecting tank 3, and a water inlet valve mechanism 4 is installed at the water inlet end of the water collecting tank 3, the water inlet valve mechanism 4 includes a valve box 49 connected to the water collecting tank 3, the side and bottom of the valve box 49 are respectively provided with a first inlet 41 and a second inlet 42, the first The inlet 41 is connected to a water intake tank 44 installed at the bottom of the river through a first connecting pipe 43, and the second inlet 42 is connected to a sewage purification tank 46 through a second connecting pipe 45. The sewage purification tank 46 is filled with water after garbage purification. A liquid level detection mechanism 5 is installed inside the water collecting tank 3 to detect the liquid level height and the rate of change of the liquid level height inside the water collecting tank 3 through the liquid level detection mechanism 5. The water inlet valve mechanism 4 adjusts the water inlet rate of the water collecting tank 3 according to the detection result of the liquid level detection mechanism 5. A movable component 7 is installed inside the water collecting tank 3. The movable component 7 moves up and down according to the liquid level height inside the water collecting tank 3 and drives the power generation component 9 outside the water collecting tank 3 to generate electricity.

[0030] In this embodiment, during the process of garbage incineration, the incinerator is cooled by the flue gas cooler 1 and the condenser 2, and the water in the river and the purified sewage in the sewage purification tank 46 are used as cooling water respectively, so as to realize the recycling of sewage and river water, and ensure that the incinerator can have a continuous supply of cooling water to ensure the cooling effect. On the other hand, in the process of the water intake tank 44 pumping river water into the water collection tank 3 and the sewage purification tank 46 pumping purified sewage into the water collection tank 3, not only the liquid level and the rate of change of the liquid level inside the water collection tank 3 are detected by the liquid level detection mechanism 5, while ensuring that the cooling water inside the water collection tank 3 can be continuously supplied, the water inlet valve mechanism 4 is used to adjust the water inlet rate of the water collection tank 3 according to the detection result of the liquid level detection mechanism 5, so as to use the change of the liquid level inside the water collection tank 3 to adjust the activity of the movable component 7, so as to drive the power generation component 9 to generate electricity through the height adjustment of the movable component 7, so as to realize the effective utilization of energy and be more energy-saving and environmentally friendly.

[0031] Specifically, river water is pumped out by a water pump inside the water intake tank 44, and enters the first inlet 41 through the first connecting pipe 43, and enters the valve box 49 through the first inlet 41, while the purified sewage in the sewage purification tank 46 is pumped out by a water pump inside the sewage purification tank 46, and enters the second inlet 42 through the second connecting pipe 45, and enters the valve box 49 through the second inlet 42, and then the water inside the valve box 49 is directly discharged into the water collection tank 3 for water supply, so that the first cooling water pump 12 and the second cooling water pump 22 inside the water collection tank 3 can pump water out of the water collection tank 3 to cool the flue gas cooler 1 and the condenser 2.

[0032] In this embodiment, a valve box 49 is separately provided outside the water collecting pool 3, so that water can be input into the water collecting pool 3 through the valve box 49, and the convection interference between the first connecting pipe 43 and the second connecting pipe 45 can be reduced, thereby facilitating operation.

[0033] In some embodiments, the first valve body 47 and the second valve body 48 are respectively installed on the side and the bottom of the valve box 49, the first connecting pipe 43 is conductively connected to the first valve body 47, the second connecting pipe 45 is conductively connected to the second valve body 48, and a control component 6 is installed inside the valve box 49 to adjust the first valve body 47 and the second valve body 48 through the control component 6.

[0034] In this embodiment, in order to manage the water flow rate discharged from the valve box 49 into the water collecting tank 3, the first valve body 47 and the second valve body 48 are respectively installed on the first connecting pipe 43 and the second connecting pipe 45, and the control component 6 is used to adjust the opening of the first valve body 47 and the second valve body 48, thereby achieving accurate adjustment of the liquid level and the rate of change of the liquid level inside the water collecting tank 3, so as to meet the activity requirements of the active component 7 to squeeze the power generation component 9 for power generation.

[0035] In some other embodiments, the movable component 7 moves up and down according to the liquid level height inside the water collecting pool 3, and the movable component 7 includes a supporting bottom plate 71 and a movable top plate 72. The supporting bottom plate 71 is movably arranged at the bottom end of the water collecting pool 3, and the movable top plate 72 is movably arranged at the top end of the water collecting pool 3. The bottom end of the supporting bottom plate 71 is connected to a first compression component 73, and the bottom end of the first compression component 73 is connected to the bottom end of the water collecting pool 3, and is used to adjust the position of the supporting bottom plate 71 according to the amount of water in the water collecting pool 3. The top end of the movable top plate 72 is connected to a second compression component 74, and the top end of the second compression component 74 is connected to the top end of the water collecting pool 3. The second compression component 74 is used to adjust the position of the movable top plate 72 according to the amount of water in the water collecting pool 3.

[0036] In this embodiment, a movable top plate 72 and a supporting bottom plate 71 are respectively installed at the top and bottom of the water collecting pool 3, and the movable top plate 72 is connected to the top of the water collecting pool 3 through the second compression component 74, and the supporting bottom plate 71 is connected to the bottom of the water collecting pool 3 through the first compression component 73. When the liquid level inside the water collecting pool 3 changes, the movable top plate 72 and the supporting bottom plate 71 rise and fall with the change of the liquid level inside the water collecting pool 3, thereby squeezing the first compression component 73 and the second compression component 74, and squeezing the power generation component 9 through the first compression component 73 and the second compression component 74 to generate electricity, and realize continuous power generation inside the water collecting pool 3 according to the change of the liquid level, so as to achieve sustainable utilization of energy and meet environmental protection requirements.

[0037] Furthermore, the power generation component 9 is arranged at the outer end of the first compression component 73 and the outer end of the second compression component 74, and the power generation component 9 is used to generate electricity according to the compression and extension of the first compression component 73 and the second compression component 74, and provide it to the first cooling water pump 12 and the second cooling water pump 22. By supplying the electricity generated by the power generation component 9 to the first cooling water pump 12 and the second cooling water pump 22, the energy can be effectively used.

[0038] In some other embodiments, the first compression assembly 73 includes a first elastic cylinder 731 installed at the bottom end of the water collecting pool 3, a first sealing plug 732 is movably installed inside the first elastic cylinder 731, a first elastic rod 734 is connected to the top end of the first sealing plug 732, the top end of the first elastic rod 734 is fixedly connected to the bottom of the support base plate 71, the bottom side of the first elastic cylinder 731 is conductively connected to a plurality of first branch cylinders 735, the first elastic cylinder 731 is filled with hydraulic oil, a floating push plate 737 is slidably installed at the top end of the first branch cylinder 735, the top end of the floating push plate 737 is connected to the first pressure rod 733, the top end of the first pressure rod 733 is installed with a first pressing head 736, the power generation assembly 9 includes a first piezoelectric device 91 arranged above the first pressing head 736, so as to push the first pressing head 736 to squeeze the first piezoelectric device 91 to generate electricity through the change of the liquid level inside the water collecting pool 3.

[0039] In this embodiment, after the cooling water enters the water collecting pool 3 through the valve box 49, as the amount of water in the water collecting pool 3 increases, the support bottom plate 71 located at the bottom end of the water collecting pool 3 is squeezed under the action of gravity, and the support bottom plate 71 is slidingly arranged along the inner wall of the water collecting pool 3. Under the action of gravity, the support bottom plate 71 slides downward along the inner wall of the water collecting pool 3, thereby squeezing the first elastic rod 734. Under the squeezing action of the first elastic rod 734, the first sealing plug 732 is pushed to slide along the inner wall of the first elastic tube 731, thereby squeezing the hydraulic oil inside the first elastic tube 731, so that the hydraulic oil enters the multiple first branch tubes 735 connected to the side of the first elastic tube 731, and generates thrust on the floating push plate 737 inside the first branch tube 735, so that the floating push plate 737 pushes the first pressure rod 733 and the first pressing head 736 to squeeze the first piezoelectric device 91, thereby causing the first piezoelectric device 91 to generate electricity. When the amount of water in the water collecting pool 3 decreases and the liquid level drops, the squeezing force of the cooling water in the water collecting pool 3 on the supporting bottom plate 71 decreases, so that the supporting bottom plate 71 gradually returns to its original position. When the water amount in the water collecting pool 3 increases and the liquid level rises next time, the first piezoelectric device 91 continues to be squeezed to continuously generate electricity.

[0040] In some other embodiments, the second compression assembly 74 includes a second elastic tube 741 installed at the top end of the water collecting pool 3, a second sealing plug 742 is movably installed inside the second elastic tube 741, the second sealing plug 742 is slidably connected to the inner wall of the second elastic tube 741 through a reset spring 746, the bottom end of the second sealing plug 742 is connected to a second elastic rod 743, the bottom end of the second elastic rod 743 is fixedly connected to the top end of the movable top plate 72, a second pressure rod 744 is installed at the top end of the second sealing plug 742, and a second pressing head 745 is connected to the top end of the second pressure rod 744, and the power generation assembly 9 also includes a second piezoelectric device 92 arranged above the second pressing head 745, so as to push the second pressing head 745 to squeeze the second piezoelectric device 92 for power generation through the change of the liquid level inside the water collecting pool 3.

[0041] Similarly, when the amount of cooling water inside the water collecting pool 3 increases and causes the liquid level to rise, as the liquid level in the water collecting pool 3 continues to rise, the buoyancy of the cooling water generates an upward thrust on the movable top plate 72 located at the top of the water collecting pool 3, which in turn generates a thrust on the second elastic rod 743, so that the second elastic rod 743 pushes the second sealing plug 742 to move upward along the inner wall of the second elastic tube 741, and the second sealing plug 742 pushes the second pressure rod 744 on the top while moving upward, and the second pressure rod 744 exerts an extrusion effect on the second pressing head 745, so that the second pressing head 745 presses the second piezoelectric device 92 to generate electricity. Similarly, after the cooling water inside the water collecting pool 3 is reduced, the liquid level drops, and the second sealing plug 742 interacts downward along the inner wall of the second elastic tube 741 under the reset action of the reset spring 746, thereby pushing the second elastic rod 743 to act on the movable top plate 72, so that the movable top plate 72 returns to its original position, and when the water volume in the water collecting pool 3 increases next time and the liquid level rises, the second piezoelectric device 92 continues to be squeezed to continuously generate electricity.

[0042] By maintaining the liquid level inside the water collection tank 3 in a changing process, the first piezoelectric device 91 and the second piezoelectric device 92 can continuously generate electricity to continuously power the first cooling water pump 12 and the second cooling water pump 22, thereby achieving sustainable use of energy.

[0043] It should be noted that the first piezoelectric device 91 and the second piezoelectric device 92 are both power generation devices made of piezoelectric materials in the prior art and are used in conjunction with a transformer. Since the content of this part of power generation is the content of the prior art, the present application does not involve specific improvements to the pressure power generation process and will not be repeated here.

[0044] In some other embodiments, the control component 6 includes a connecting tube 61 installed on the outside of the valve box 49 and connected to the water collecting tank 3, and the inner wall of the valve box 49 is respectively installed with a first transfer box 62 connected to the first valve body 47 and a second transfer box 63 connected to the second valve body 48, and the first transfer box 62 and the second transfer box 63 are both connected to the connecting tube 61 through a connecting groove 64, and a cleaning groove 65 is installed at the bottom of the connecting groove 64, and the cleaning groove 65 is connected to the connecting groove 64 through a third valve body 66, and the cleaning groove 65 is installed with the first transfer box 62 respectively facing the first transfer box 62 and a spray head 67 of the second transfer box 63, the spray head 67 is connected to the third valve body 66 and faces the first transfer box 62 and the second transfer box 63 respectively, so as to clean the inner walls of the first transfer box 62 and the second transfer box 63 by spraying high-pressure water columns through the spray head 67, the side of the second transfer box 63 away from the cleaning groove 65 and the connecting groove 64 are both connected to the inside of the connecting tube 61, the bottom surface of the second transfer box 63 and the bottom surface of the connecting tube 61 are located in the same inclined plane, and the height of the inclined plane close to one end of the second transfer box 63 is greater than the height close to one end of the connecting tube 61.

[0045] In this embodiment, while the valve box 49 is provided, the first transfer box 62 and the second transfer box 63 are provided at the bottom and one side of the valve box 49, so that the river cooling water entering the first transfer box 62 from the first valve body 47 and the sewage purified water entering the second transfer box 63 from the second valve body 48 are mixed in the connection groove 64 and concentrated in the valve box 49, so as to enter the water collection tank 3 through the valve box 49. By providing the first transfer box 62 and the second transfer box 63 which are tilted and opposed to each other, the two streams of water sprayed from the first valve body 47 and the second valve body 48 can be smoothly merged to reduce the impact. On the other hand, considering that there may be sediment in the river water, and there may be sediment in the purified sewage for a long time, which may cause blockage in the first valve body 47 and the first transfer box 62, a cleaning groove 65 is installed at the bottom of the connection groove 64, and the conduction of the connection groove 64 and the cleaning groove 65 is controlled by the third valve body 66. When cleaning is required after long-term use, the first valve body 47 and the second valve body 48 are first closed, and the third valve body 66 is opened to discharge the water remaining inside the valve box 49 and spray it to the inner walls of the first transfer box 62 and the second transfer box 63 through the spray head 67, thereby cleaning the inner walls of the first transfer box 62 and the second transfer box 63, effectively preventing blockage inside the first transfer box 62 and the second transfer box 63 and affecting the water output efficiency.

[0046] Furthermore, since the side of the second transfer box 63 away from the cleaning groove 65 and the connecting groove 64 are both connected to the interior of the connecting tube 61, the bottom surface of the second transfer box 63 and the bottom surface of the connecting tube 61 are located on the same inclined plane, and the height of the inclined plane close to one end of the second transfer box 63 is greater than the height close to one end of the connecting tube 61, and the bottom height of the valve box 49 is higher than the bottom height of the water collection tank 3, so that the water after flushing the first transfer box 62 enters the connecting tube 61 through the connecting groove 64 and then enters the water collection tank 3, while the water after flushing the second transfer box 63 directly enters the interior of the connecting tube 61 and enters the water collection tank 3, thereby avoiding blockage inside the valve box 49.

[0047] In some other embodiments, the control assembly 6 further includes a controller 68 disposed outside the water collecting tank 3, and the controller 68 is used to adjust the first valve body 47 and the second valve body 48 according to the liquid level and the rate of change of the liquid level detected by the liquid level detection mechanism 5;

[0048] When the liquid level detection mechanism 5 detects that the liquid level inside the water collection tank 3 reaches a first preset height and the liquid level in the water collection tank 3 is in an ascending state, the controller 68 reduces the valve openings of the first valve body 47 and the second valve body 48 so that the liquid level in the water collection tank 3 is in a descending state;

[0049] When the liquid level detection mechanism 5 detects that the liquid level inside the water collection tank 3 reaches a second preset height and the liquid level in the water collection tank 3 is in a descending state, the controller 68 increases the valve openings of the first valve body 47 and the second valve body 48 so that the liquid level in the water collection tank 3 is in an ascending state;

[0050] When the liquid level detection mechanism 5 detects that the liquid level inside the water collection tank 3 is between the first preset height and the second preset height, the valve openings of the first valve body 47 and the second valve body 48 are adjusted to make the liquid level in the water collection tank 3 rise or fall;

[0051] Among them, when the first compression component 73 is fully compressed, the liquid level height inside the water collecting pool 3 is the first liquid level height, when the second compression component 74 is fully compressed, the liquid level height inside the water collecting pool 3 is the second liquid level height, and the first preset height is the smaller of the first liquid level height and the second liquid level height; when the first compression component 73 is not squeezed at all, the highest liquid level height of the water collecting pool 3 is the third liquid level height, when the second compression component 74 is not squeezed at all, the highest liquid level height of the water collecting pool 3 is the fourth liquid level height, the second preset height is the larger of the third liquid level height and the fourth liquid level height, and the first preset height is greater than the second preset height.

[0052] It should be noted that the liquid level detection mechanism 5 in the present application scheme adopts a device of the prior art. The present scheme does not involve improvements to the liquid level detection mechanism 5 itself. Any liquid level detection device that can detect the liquid level height and liquid level change rate inside the water collection tank 3 in the present scheme can be applied to the present application scheme. The present scheme does not make any special mention of this and will not be repeated here.

[0053] In this embodiment, during the process of delivering river water and sewage purified water into the water collecting tank 3, the controller 68 adjusts the water inlet speed and the liquid level inside the water collecting tank 3 by controlling the valve opening of the first valve body 47 and the second valve body 48, thereby ensuring that the liquid level inside the water collecting tank 3 is in a dynamic change process, thereby facilitating the extrusion power generation of the power generation component 9 through the dynamic change of the liquid level inside the water collecting tank 3, thereby achieving effective utilization of energy.

[0054] During specific adjustment, when the liquid level detection mechanism 5 detects that the liquid level inside the water collecting pool 3 reaches a first preset height and the liquid level in the water collecting pool 3 is in an ascending state, the controller 68 reduces the valve openings of the first valve body 47 and the second valve body 48. Since the first preset height is the smaller of the first liquid level and the second liquid level, and at this time one of the first compression assembly 73 and the second compression assembly 74 has reached the maximum compression limit, the controller 68 reduces the openings of the first valve body 47 and the second valve body 48 so that the water inlet speed of the water collecting pool 3 is less than the water outlet speed, thereby causing the liquid level in the water collecting pool 3 to be in a descending state, so as to facilitate the next round of extrusion power generation.

[0055] When the liquid level detection mechanism 5 detects that the liquid level inside the water collection tank 3 reaches the second preset height, and the liquid level of the water collection tank 3 is in a descending state, the controller 68 increases the valve opening of the first valve body 47 and the second valve body 48. Since the second preset height is the larger of the third liquid level and the fourth liquid level, at this time, at least one of the first compression assembly 73 and the second compression assembly 74 is already in a completely loosened state, and the controller 68 increases the opening of the first valve body 47 and the second valve body 48 to make the water inlet speed in the water collection tank 3 greater than the water outlet speed, so that the liquid level inside the water collection tank 3 is in an ascending state, so as to squeeze the first compression assembly 73 and the second compression assembly 74 again to prompt the power generation assembly 9 to continue to generate electricity.

[0056] When the liquid level detection mechanism 5 detects that the liquid level inside the water collecting tank 3 is between the first preset height and the second preset height, the valve openings of the first valve body 47 and the second valve body 48 are adjusted to make the liquid level in the water collecting tank 3 rise or fall, so as to ensure that the liquid level inside the water collecting tank 3 is always in a dynamic change process, so as to facilitate the first compression component 73 and the second compression component 74 to continuously compress and release the power generation component 9.

[0057] It should be noted that before and after the first valve body 47 and the second valve body 48 are adjusted, the water inlet speed in the water collecting tank 3 is greater than or less than the water outlet speed, thereby ensuring that the liquid level inside the water collecting tank 3 is always in dynamic change, so as to ensure that the first compression component 73 and the second compression component 74 can be continuously compressed and released in a continuous cycle by continuously changing the liquid level inside the water collecting tank 3, so as to achieve continuous power generation by continuously squeezing and releasing the power generation component 9.

[0058] In some other embodiments, the drainage ends of the flue gas cooler 1 and the condenser 2 are both connected to a return pipe 8, the ends of the return pipe 8 are connected to a collecting pipe 81, the ends of the collecting pipe 81 are connected to a filter tank 82, and the output ends of the filter tank 82 are respectively connected to a first branch pipe 83 and a second branch pipe 84, the first branch pipe 83 is used to discharge the filtered water into the river, and the second branch pipe 84 is used to discharge the filtered water back into the sewage treatment discharge pipe.

[0059] After the first cooling water pump 12 and the second cooling water pump 22 draw the cooling water from the water collecting tank 3 and send it to the flue gas cooler 1 and the condenser 2 for cooling, the cooling water is discharged again through the return pipe 8 and concentrated in the central pipe 81 before being discharged into the filter tank 82 for unified filtration. After filtration, the filtered water is discharged into the river through the first branch pipe 83, and the water discharged through the second branch pipe 84 is discharged again into the sewage treatment discharge pipe dedicated to sewage purification water to prevent affecting the sewage treatment discharge pipe and water pump.

[0060] The cooling water calling device for waste incineration treatment described in the present application not only pumps outdoor river water into the water collection tank for use as cooling water through a water intake pump, but also pumps purified water obtained after sewage purification in the sewage purification tank into the water collection tank for use as cooling water, effectively improving the utilization efficiency of outdoor river water and water after sewage purification, and in the process of sending river water and purified water into the water collection tank, the liquid level and the rate of change of the liquid level inside the water collection tank are detected by a liquid level detection mechanism, so that the water inlet rate of the water inlet valve mechanism can be adjusted by the control component, which can not only achieve water supply balance inside the water collection tank, but also use the change of the liquid level inside the water collection tank to adjust the active component, so that the active component can be used to squeeze the first piezoelectric device and the second piezoelectric device in the power generation component to generate electricity, so that the electricity generated by the first piezoelectric device and the second piezoelectric device can power the first cooling water pump and the second cooling water pump, thereby achieving effective utilization of resources.
