At present, the treatment method of household garbage is generally two kinds, one is sanitary landfill, and the other is incineration power generation. Waste incineration power generation has the characteristics of small occupation, obvious reduction effect, and waste heat resource utilization compared with sanitary landfill. Therefore, waste incineration power generation has gradually replaced the method of sanitary landfill. In the related technology, the waste incineration power generation process is generally that the waste is put into the grate of the waste incinerator. The heat is diffused outward during the incineration process of the waste in the waste incinerator. The inner wall of the waste incinerator is provided with a water cooled wall. The heat generated in the waste incinerator is absorbed by the water cooled wall, so that the water in the water cooled wall evaporates to generate water vapor. After the water vapor is further treated by the economizer, the steam drum and the superheater device, it enters the steam turbine to drive the steam turbine to generate power. However, the flue gas generated during the incineration process contains a lot of smoke dust. After a long time, the smoke dust will accumulate on the water cooled wall, which will reduce the heat conduction effect of the water cooled wall and affect the normal work of the water cooled wall.

[0038] Please refer to the drawings of the present application Figure 1 - the drawings of the present application Figure 4The embodiment of the present application provides the cooling device of the precise temperature control partition type incinerator, and the hearth 1 of the partition type incinerator is arranged, wherein the partition type incinerator is a kind of efficient environmental protection waste treatment equipment, by using airflow organization (set air inlet at the bottom of cylindrical hearth 1, so that air enters hearth 1 at specific angle and speed, forms rotating upward airflow), rely on temperature distribution (utilize temperature difference of different height positions of hearth 1 to divide functional area) and the like, can be divided into preheating, combustion, burnout and the like from top to bottom in hearth 1, its specific structure belongs to prior art, not more description here, the inner wall of hearth 1 is fixedly provided with water cooled wall 2, the upper side wall of hearth 1 is fixedly provided with liquid inlet end 3 and gas outlet end 8, and the lower side wall of hearth 1 is fixedly provided with liquid outlet end 7, the inner wall of water cooled wall 2 is rotatably connected with top plate 12 and bottom plate 4 respectively on the upside and downside, the opposite side of top plate 12 and bottom plate 4 is fixedly connected with helical blade 5, a plurality of flow-through holes are formed in the surface of top plate 12, cleaning assembly 6 is installed on the upside of top plate 12, cleaning assembly 6 includes gear ring one 61, gear ring one 61 is fixedly installed on the upper surface of top plate 12, the tooth end of gear ring one 61 is meshingly connected with gear ring two 62, the center of gear ring two 62 is fixedly connected with connecting shaft 63, a plurality of driving blades 64 are fixedly connected to the outer wall of connecting shaft 63, and the outer wall of connecting shaft 63 is rotatably connected with the upper surface of water cooled wall 2, the inner side wall of helical blade 5 is attached to the inner side wall of hearth 1, and the inner side wall of helical blade 5 is attached to the inner side wall of water cooled wall 2, a plurality of thermocouples or thermistor temperature sensors are installed at key positions of water cooled wall 2, such as four corners of hearth 1, burner vicinity, higher heat load area and the like, to measure wall temperature of water cooled wall 2 in real time and accurately, high-precision flow regulating valve and flowmeter are installed on liquid inlet end 3, according to the signal fed back by temperature sensor, cooling water flow entering water cooled wall 2 is automatically adjusted, when water cooled wall 2 temperature rises, cooling water flow is increased, when temperature decreases, flow is reduced, simultaneously, flow of cooling water is monitored in real time through flowmeter, to ensure the accuracy of flow control, PID control algorithm or more complex intelligent control algorithm is used, according to temperature change and load change of water cooled wall 2, feedwater flow is automatically adjusted, so that working fluid flow in water cooled wall 2 matches the heat load of boiler, to ensure that the temperature of water cooled wall 2 is stably in set value range.

[0039] Specifically, the liquid inlet end 3 is used to add water to the inside of the water-cooled wall 2, the flow-through hole is used to allow the water to flow downward through the top plate 12, the spiral blade 5 can prolong the water flow path, prolong the heat exchange time, and the spiral flow of the water flow caused by the spiral blade 5 increases the scouring effect of the water flow on the pipe wall, making it difficult for scale to deposit and adhere to the pipe wall, thereby reducing the scale thermal resistance. The combustion of waste and other combustion materials in the furnace 1 causes heat to be absorbed by the water in the water-cooled wall 2, causing the water to evaporate. The evaporated water vapor enters the subsequent coal economizer, steam drum, superheater, and other processing devices in sequence through the gas outlet end 8. When the water flow exits the liquid inlet end 3, it acts on the driving blade 64 to push the connecting shaft 63 to rotate, the connecting shaft 63 drives the gear ring two 62 to rotate, the gear ring two 62 drives the gear ring one 61 to rotate, the gear ring one 61 drives the top plate 12 to rotate, and the top plate 12 drives the spiral blade 5 to rotate. When the spiral blade 5 rotates, it can clean the area where water is stored between the furnace 1 and the water-cooled wall 2, scraping off the adhered scale, thereby long-term maintaining the heat conduction effect of the inside of the water-cooled wall 2.

[0040] Please refer to the accompanying drawings Figure 5 The upper side wall of the connecting shaft 63 is fixedly connected with a gear ring three 65, the tooth end of the gear ring three 65 is meshingly connected with a gear ring four 66, the inner side wall of the gear ring four 66 is fixedly connected with a plurality of scrapers 67, and the bottom end of the gear ring four 66 is rotatably connected with the upper surface of the water-cooled wall 2.

[0041] Specifically, when the connecting shaft 63 rotates, it drives the gear ring three 65 to rotate, the gear ring three 65 drives the gear ring four 66 to rotate, and the gear ring four 66 drives the scraper 67 to rotate, so that the scraper 67 can clean the outer side wall of the water-cooled wall 2, causing the soot on the inner circumferential surface of the water-cooled wall 2 to fall into the furnace cavity, reducing the influence of soot on the guiding effect of the outer side of the water-cooled wall 2, and thereby maintaining the heat conduction effect of the water-cooled wall 2 at a relatively good level.

[0042] Please refer to the accompanying drawings Figure 5 The bottom end of the plurality of scrapers 67 is fixedly connected with a connecting ring 68, the bottom of the water-cooled wall 2 is provided with a groove, the connecting ring 68 is arranged inside the groove, the top end of the gear ring four 66 is fixedly connected with a ring-shaped shielding cover 69, and the bottom end of the outer side of the shielding cover 69 is rotatably connected with the upper surface of the water-cooled wall 2.

[0043] Specifically, the groove is used to accommodate the connecting ring 68, the connecting ring 68 is used to connect the bottom end of the scraper 67, and the stability of the connection of the scraper 67 is improved. The shielding cover 69 is used to shield the gear ring three 65 and the gear ring four 66 to prevent soot from falling into the gear slot.

[0044] Please refer to the accompanying drawings Figure 6 -Appendix Figure 7The scraper 67 comprises a mounting frame 671, and a gap is left between the inner side wall of the mounting frame 671 and the inner side wall of the water cooling wall 2. An installation groove is formed in the inner side wall of the mounting frame 671, and a cleaning plate 672 is rotatably connected to the inner wall of the installation groove through a rotating shaft. A rotating frame 673 is rotatably connected to the side wall of the cleaning plate 672 through a rotating shaft. A sliding plate 674 is slidably connected to the side wall of the cleaning plate 672 through a rotating shaft. The cleaning plate 672 is arranged on the front side of the scraper 67 in the rotating direction of the scraper 67.

[0045] Specifically, when the scraper 67 rotates, the sliding plate 674 is slid to the cleaning plate 672 by the air resistance, and the cleaning plate 672 is rotated to the water cooling wall 2 by the rotating frame 673, so as to clean the water cooling wall 2.

[0046] Please refer to the accompanying drawings Figure 7 The side wall of the sliding plate 674 is fixedly connected with a flexible connecting piece 675, such as a ceramic fiber rope or a nichrome wire rope. The other end of the connecting piece 675 is fixedly connected with a counterweight 676 penetrating through the mounting frame 671. The gravity of the counterweight 676 is smaller than the air resistance applied to the sliding plate 674 when the scraper 67 rotates.

[0047] Specifically, when the scraper 67 stops rotating, the connecting piece 675 pulls the sliding plate 674 to slide away from the cleaning plate 672 by the downward pulling force of the counterweight 676, and the cleaning plate 672 is rotated to the inside of the installation groove by the rotating frame 673, so as to avoid affecting the heat conduction effect of the contact area when the cleaning plate 672 abuts against the water cooling wall 2 after cleaning.

[0048] Please refer to the accompanying drawings Figure 4 The liquid inlet end 3 comprises a liquid inlet pipe 31, and a shunt pipe 32 is fixedly arranged at one end of the liquid inlet pipe 31. A conveying pipe one 33 and a conveying pipe two 34 are fixedly arranged at the upper side and the lower side of the shunt pipe 32, respectively, and are in communication with the furnace 1. An electromagnetic valve one 35 is fixedly arranged on the surface of the conveying pipe one 33, and an electromagnetic valve two 36 is fixedly arranged at the center of the shunt pipe 32.

[0049] Specifically, water is input through the liquid inlet pipe 31, when cleaning is needed, the electromagnetic valve one 35 is opened and the electromagnetic valve two 36 is closed, the water flow enters the water-cooled wall 2 through the conveying pipe one 33 and drives the driving blades 64 to rotate, achieving the cleaning effect, and when stopping cleaning, the electromagnetic valve one 35 is closed and the electromagnetic valve two 36 is opened, so that the water flow enters the water-cooled wall 2 through the conveying pipe two 34, and the driving blades 64 are not driven to rotate, so that the spiral blades 5 and the cleaning plate 672 stop rotating. Since the water-cooled wall 2 needs to be cleaned after a long time of operation, when the water flow is conveyed through the conveying pipe two 34, the abrasion of the spiral blades 5 and the cleaning plate 672 can be reduced during use of the device, and the service life of the two is prolonged.

[0050] Please refer to the accompanying drawings Figure 8 -Appendix Figure 10 The filter assembly 9 for filtering scale is installed at the liquid outlet end 7, the filter assembly 9 comprises a cylinder body 901, the lower side wall of the cylinder body 901 is fixedly connected with the liquid outlet end 7, a reflux end 10 is fixedly arranged at the center of the cylinder body 901, the reflux end 10 is higher than the gas outlet end 8, a separation layer 902 is fixedly connected inside the cylinder body 901, a lower connecting rod 903 is arranged through the surface of the separation layer 902, a filter cartridge 904 is fixedly connected to the bottom end of the lower connecting rod 903, and an I-shaped upper connecting rod 905 is fixedly connected to the top end of the lower connecting rod 903. The top end of the upper connecting rod 905 penetrates the top end of the cylinder body 901 and the bottom end of the shunt pipe 32.

[0051] Specifically, when stopping cleaning, the electromagnetic valve two 36 is in an open state, the water flow flows to the lower side area of the shunt pipe 32, and the impact force of the water flow acting on the top end of the upper connecting rod 905 pushes the upper connecting rod 905, the lower connecting rod 903 and the connected filter cartridge 904 downward, so that the filter cartridge 904 is lowered and deviated from the liquid outlet end 7, avoiding affecting the flow rate of the water flow in the cylinder body 901, and making the water flow more smoothly back to the pool through the reflux end 10.

[0052] Please refer to the accompanying drawings Figure 8 -Appendix Figure 10 The outer side wall of the lower connecting rod 903 is sleeved with an elastic element 907, which can be a steel plate spring, a spiral spring, a torsion bar spring, a rubber spring, etc. In the embodiment, a fatigue-resistant spiral spring made of stainless steel is adopted, the elastic element 907 is located above the separation layer 902, and the outer side wall of the upper connecting rod 905 is provided with a connecting pipe 11, both ends of the connecting pipe 11 are fixedly connected with the top end of the cylinder body 901 and the bottom end of the shunt pipe 32.

[0053] Specifically, the connecting pipe 11 can avoid the water leakage problem of the upper connecting rod 905 and the penetration of the cylinder body 901 and the shunt pipe 32, and can also be provided with a sealing structure at the penetration of the upper connecting rod 905 and the cylinder body 901 and the shunt pipe 32 to seal the way. When cleaning, the electromagnetic valve 36 is in a closed state, the water flow does not flow to the lower side area of the shunt pipe 32, the impact force on the upper connecting rod 905 disappears, the upper connecting rod 905 can be lifted upward through the elastic member 907, and the lower connecting rod 903 and the connected filter cartridge 904 are lifted, so that the top end of the filter cartridge 904 moves close to the separation layer 902. At this time, when the water flow flows out through the liquid outlet 7, it needs to pass through the filter cartridge 904 to filter the cleaned scale before it can flow out from the backflow end 10. The filter cartridge 904 can avoid or reduce the flow of scale, achieving the effect of collecting scale.

[0054] Please refer to the accompanying drawings Figure 8 -Appendix Figure 10 The center of the filter cartridge 904 is rotatably connected with a drainage pipe 909, the inner bottom wall of the drainage pipe 909 is fixedly provided with a limiting protrusion, the upper inner wall of the drainage pipe 909 is fixedly connected with an impeller 910, the lower outer wall of the drainage pipe 909 is fixedly connected with a T-shaped spray head 911, the outer side wall of the spray head 911 is fixedly connected with a cleaning sheet 912, the bottom end of the cylinder body 901 is open, and the bottom end of the cylinder body 901 is threadedly connected with a sealing cover 908. The center of the sealing cover 908 is fixedly connected with a pressing column 913, the top end of the pressing column 913 is provided with a piston block 914, the piston block 914 is slidably arranged in the inside of the drainage pipe 909, and the top of the filter cartridge 904 is provided with a plurality of water permeable holes.

[0055] Specifically, the limiting protrusion is used to prevent the piston block 914 from falling out of the drainage pipe 909. After stopping cleaning, the filter cartridge 904 carrying scale agglomerates descends to the bottom of the filter cartridge 904. When the scale needs to be discharged, the sealing cover 908 is unscrewed and removed, and the scale falls out of the bottom opening of the cylinder body 901. At this time, part of the water flow in the cylinder body 901 flows downward through the drainage pipe 909, the water flow pushes the piston block 914 to slide downward, and the water flow passing through the drainage pipe 909 drives the impeller 910 to rotate. The impeller 910 drives the drainage pipe 909 to rotate, the drainage pipe 909 drives the spray head 911 to rotate, so that the water flow can be sprayed out from the spray head 911, and the residual scale on the inner wall of the filter cartridge 904 can be cleaned. At the same time, the rotation of the spray head 911 drives the cleaning sheet 912 to rotate, which can scrape off the scale, achieving a double cleaning effect, effectively avoiding or splashing the scale remaining in the filter cartridge 904. After cleaning is completed, the sealing cover 908 is reinstalled. At this time, the pressing column 913 is inserted into the drainage pipe 909 and pushes the piston block 914 upward, so that the piston block 914 is higher than the connection between the spray head 911 and the drainage pipe 909, so that the water flow does not flow downward through the drainage pipe 909, thereby stopping the rotation of the impeller 910 and reducing the wear degree of the cleaning sheet 912, thereby prolonging the service life.

[0056] While embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
