Description

Technical Field

[0001] The present invention relates to the technical field of incinerators, and in particular to a precise temperature-controlled zoned incinerator cooling device. Background Art

[0002] With the improvement of people's living standards, the amount of domestic waste generated in urban and rural areas has increased dramatically. At present, there are generally two ways to deal with domestic waste, one is sanitary landfill, and the other is incineration power generation. Compared with sanitary landfill, waste incineration power generation has the significant advantages of small footprint, obvious reduction effect, and utilization of waste heat resources. Therefore, waste incineration power generation has gradually replaced the sanitary landfill method. In related technologies, the waste incineration power generation process is generally to put the garbage onto the grate in the waste incinerator. During the incineration process in the waste incinerator, the garbage will diffuse heat outward. A water-cooled wall is provided on the inner wall of the waste incinerator. The heat generated in the waste incinerator will be absorbed by the water-cooled wall, causing the water in the water-cooled wall to evaporate and produce water vapor. The water vapor is further treated by the economizer, steam drum, and superheater device and then enters the steam turbine to drive the steam turbine to generate electricity. The flue gas generated during the incineration of garbage will contain a lot of smoke dust. After a long time, these smoke dusts will accumulate on the water-cooled wall, resulting in a decrease in the thermal conductivity of the water-cooled wall, affecting the normal operation of the water-cooled wall.

[0003] A search revealed a waste incinerator disclosed in publication number CN112594691B, which relates to the field of waste incineration equipment. The incinerator comprises a furnace body, a furnace cavity provided therein, a feed port and a discharge port provided on the furnace body, a grate arranged between the feed port and the discharge port, a water-cooled wall provided on the inner wall of the furnace body, a water storage cavity provided inside the water-cooled wall, the water storage cavity being connected to an external water source, an air outlet pipe connected to the water storage cavity provided on the water-cooled wall, and a cleaning device for cleaning smoke and dust from the surface of the water-cooled wall provided on the furnace body. The cleaning device comprises a cleaning blade arranged along the height direction of the water-cooled wall, the cleaning blade being in contact with the water-cooled wall, and a drive assembly for driving the cleaning blade to scrape the surface of the water-cooled wall in a circular motion. The present application has the advantage of being able to clean dust from the water-cooled wall in the furnace cavity in real time.

[0004] In the above application, the outer wall of the water-cooled wall is cleaned, but the inner wall of the water-cooled wall will produce scale after long-term use and also needs to be cleaned. The above application lacks corresponding cleaning means. Summary of the Invention

[0013] Preferably, the outer wall of the lower connecting rod is sleeved with an elastic member, and the elastic member is located above the partition layer. The outer wall of the upper connecting rod is provided with a connecting pipe, and the two ends of the connecting pipe are respectively fixedly connected to the top end of the cylinder and the bottom end of the diversion pipe.

[0014] Preferably, a drainage tube is rotatably connected to the center of the filter cartridge, a limiting protrusion is fixedly provided on the inner bottom wall of the drainage tube, an impeller is fixedly connected to the upper inner wall of the drainage tube, a T-shaped nozzle is fixedly connected to the lower outer wall of the drainage tube, and a cleaning sheet is fixedly connected to the outer wall of the nozzle.

[0016] Working principle: Combustible materials such as garbage are thrown into the furnace from the top for incineration. The heat generated during the combustion process will be absorbed by the water in the water-cooled wall and cause the water to evaporate. The evaporated water vapor enters the subsequent economizer, steam drum, superheater and other treatment devices in sequence through the gas outlet. When the water flows out of the liquid inlet, it acts on the driving blades to push the connecting shaft to rotate. The rotation of the connecting shaft drives the gear ring 2 to rotate, the gear ring 2 drives the gear ring 1 to rotate, the gear ring 1 drives the top plate to rotate, and the top plate drives the spiral blades to rotate. When the spiral blades rotate, the water storage area between the furnace and the water-cooled wall can be cleaned and the attached scale can be scraped off, thereby maintaining the thermal conductivity of the inner side of the water-cooled wall for a long time.

[0017] When the connecting shaft rotates, it drives the gear ring three to rotate, the gear ring three drives the gear ring four to rotate, and the gear ring four drives the scraper to rotate, so that the scraper can clean the outer wall of the water-cooled wall, so that the smoke and dust on the inner surface of the water-cooled wall falls into the furnace cavity, reducing the influence of the smoke and dust on the guiding effect of the outer side of the water-cooled wall, so that the heat conduction effect of the water-cooled wall is always maintained at a better effect.

[0018] Water is input through the liquid inlet pipe. When cleaning is needed, open solenoid valve 1 and close solenoid valve 2. Water flows into the water-cooled wall through delivery pipe 1 and drives the driving blades to rotate, thereby achieving the cleaning effect. When cleaning is stopped, close solenoid valve 1 and open solenoid valve 2, so that water flows into the water-cooled wall through delivery pipe 2 and no longer drives the driving blades to rotate, causing the spiral blades and scrapers to stop rotating. Since the water-cooled wall needs to be cleaned only after running for a long time, when water is delivered through delivery pipe 2 at this time, the wear of the spiral blades and scrapers can be reduced when the device is in use, thereby extending the service life of the two.

[0019] When cleaning is stopped, solenoid valve 2 is in the open state, and water flows to the lower area of the diversion pipe. The impact force of the water flow on the top of the upper connecting rod pushes the upper connecting rod, the lower connecting rod and the connected filter cartridge down, so that the filter cartridge drops away from the liquid outlet, avoiding the filter cartridge affecting the flow rate of the water in the cylinder, so that the water flows more smoothly back to the pool through the return end. When cleaning, solenoid valve 2 is in the closed state, and the water no longer flows to the lower area of the diversion pipe. The impact force on the upper connecting rod disappears, and the upper connecting rod can be pushed upward by the elastic part, and the lower connecting rod and the connected filter cartridge are driven to rise, so that the top of the filter cartridge is against the partition layer. At this time, when the water flows out through the liquid outlet, it needs to be filtered by the filter cartridge to filter the cleaned scale before it can flow out from the return end. The filter cartridge can avoid or reduce the outflow of scale, thereby achieving the effect of collecting scale.

[0020] After stopping cleaning, the filter cartridge carrying scale agglomerates drops to the bottom of the filter cartridge. When the scale needs to be discharged, unscrew and remove the sealing cover, and the scale falls from the opening at the bottom of the cylinder. At the same time, part of the water in the cylinder flows downward through the drainage pipe, and the water pushes the piston block to slide downward. When the water flows through the drainage pipe, it drives the impeller to rotate, and the impeller drives the drainage pipe to rotate, and the drainage pipe drives the nozzle to rotate, so that the water can be rotated and sprayed out from the nozzle to clean the scale remaining on the inner wall of the filter cartridge. At the same time, the nozzle drives the cleaning piece to rotate to scrape off the scale, achieving a double cleaning effect, effectively avoiding or splashing scale residue inside the filter cartridge. After cleaning is completed, reinstall the sealing cover, at this time insert the drainage pipe through the extrusion column and push the piston block upward, so that the piston block is higher than the connection between the nozzle and the drainage pipe, so that the water no longer flows downward through the drainage pipe, thereby stopping the impeller from rotating, reducing the wear of the cleaning piece, thereby extending the service life.

[0021] The present invention provides a precise temperature-controlled zoned incinerator cooling device. It has the following beneficial effects: 1. The present invention drives the driving blades to rotate by inputting water flow through a delivery pipe, which drives the spiral blades to rotate. When the spiral blades rotate, the water storage area between the furnace and the water-cooled wall can be cleaned and the attached scale can be scraped off, thereby maintaining the heat conduction effect on the inner side of the water-cooled wall for a long time.

[0022] 2. The present invention can clean the outer wall of the water-cooled wall by rotating the scraper, so that the smoke and dust on the inner peripheral surface of the water-cooled wall falls into the furnace cavity, reducing the influence of the smoke and dust on the heat conduction effect of the outer side of the water-cooled wall, so that the heat conduction effect of the water-cooled wall is always maintained at a better effect.

[0023] 3. The present invention uses an automatically rising and falling filter cartridge. When cleaning stops, the filter cartridge descends and is staggered with the liquid outlet end, avoiding the filter cartridge affecting the flow rate of water in the cartridge body, allowing the water to flow out more smoothly. During cleaning, the filter cartridge rises to filter scale agglomerates in the water, thereby achieving the effect of collecting scale.

[0024] 4. The present invention can discharge scale by removing the sealing cover, and the scale remaining on the inner wall of the filter cartridge can be cleaned by rotating the nozzle to spray water and cooperate with the cleaning sheet, effectively avoiding or splashing scale residue inside the filter cartridge.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Please see the attached Figure 1 -Attached Figure 4The embodiment of the present invention provides a precise temperature control zoned incinerator cooling device, including a zoned incinerator furnace 1, wherein the zoned incinerator is a highly efficient and environmentally friendly waste treatment equipment, by utilizing air flow organization (arranging an air inlet at the bottom of the cylindrical furnace 1 so that air enters the furnace 1 at a specific angle and speed to form a rotating upward airflow), relying on temperature distribution (using the temperature difference at different height positions of the furnace 1 to divide the functional areas), etc., the interior of the furnace 1 can be divided from top to bottom into preheating, The specific structure of the furnace 1 is a plurality of functional areas such as combustion and burnout, which belongs to the prior art and will not be described here. The inner wall of the furnace 1 is fixedly provided with a water-cooled wall 2, the upper side wall of the furnace 1 is fixedly provided with a liquid inlet 3 and an air outlet 8, and the lower side wall of the furnace 1 is fixedly provided with a liquid outlet 7. The upper and lower sides of the inner wall of the water-cooled wall 2 are respectively rotatably connected with a top plate 12 and a bottom plate 4. The opposite side of the top plate 12 and the bottom plate 4 is fixedly connected with a spiral blade 5. The surface of the top plate 12 is provided with a plurality of flow holes, and a cleaning component is installed on the upper side of the top plate 12. 6. The cleaning assembly 6 includes a gear ring 1 61, which is fixedly mounted on the upper surface of the top plate 12. The tooth end of the gear ring 1 61 is meshedly connected with the gear ring 2 62. The center of the gear ring 2 62 is fixedly connected with a connecting shaft 63. The outer wall of the connecting shaft 63 is fixedly connected with a plurality of driving blades 64. The outer wall of the connecting shaft 63 is rotatably connected to the upper surface of the water-cooled wall 2. The outer wall of the spiral blade 5 is attached to the inner wall of the furnace 1, and the inner wall of the spiral blade 5 is attached to the inner wall of the water-cooled wall 2. At the key parts of the water-cooled wall 2, such as Multiple thermocouples or thermal resistor temperature sensors are installed at the four corners of the furnace 1, near the burner, and in areas with high heat load, to accurately measure the wall temperature of the water-cooled wall 2 in real time. A high-precision flow control valve and flow meter are installed on the liquid inlet end 3. The amount of cooling water entering the water-cooled wall 2 is automatically adjusted according to the signal fed back by the temperature sensor. When the temperature of the water-cooled wall 2 rises, the cooling water flow is increased; when the temperature drops, the flow is reduced. At the same time, the cooling water flow is monitored in real time by the flow meter to ensure the accuracy of flow control. By adopting PID control algorithm or more complex intelligent control algorithm, the feed water flow is automatically adjusted according to the temperature change and load change of the water-cooled wall 2, so that the working medium flow in the water-cooled wall 2 matches the heat load of the boiler, ensuring that the temperature of the water-cooled wall 2 is stable within the set value range.

[0029] Specifically, the liquid inlet end 3 is used to add water to the inside of the water-cooled wall 2, and the flow hole is used to supply water to flow downward through the top plate 12. The spiral blades 5 can extend the water flow path and extend the heat exchange time. The spiral flow of the water caused by the spiral blades 5 increases the scouring effect of the water flow on the tube wall, making it difficult for scale to deposit and adhere on the tube wall, thereby reducing the scale thermal resistance. When the combustible materials such as garbage are put into the furnace 1 from the top for incineration, the heat generated during the combustion process will be absorbed by the water in the water-cooled wall 2, causing the water to evaporate. The evaporated water vapor passes through the furnace 1. The gas outlet end 8 enters the subsequent economizer, steam drum, superheater and other processing devices in turn. When the water flows out of the liquid inlet end 3, it acts on the driving blade 64 to push the connecting shaft 63 to rotate. The rotation of the connecting shaft 63 drives the gear ring 2 62 to rotate. The gear ring 2 62 drives the gear ring 1 61 to rotate. The gear ring 1 61 drives the top plate 12 to rotate. The top plate 12 drives the spiral blade 5 to rotate. When the spiral blade 5 rotates, the water storage area between the furnace 1 and the water-cooled wall 2 can be cleaned and the attached scale can be scraped off, thereby maintaining the heat conduction effect on the inside of the water-cooled wall 2 for a long time.

[0030] Please see the attached 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 meshedly 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 to the upper surface of the water-cooled wall 2.

[0031] Specifically, when the connecting shaft 63 rotates, the gear ring 3 65 is driven to rotate, the gear ring 3 65 drives the gear ring 4 66 to rotate, and the gear ring 4 66 drives the scraper 67 to rotate, so that the scraper 67 can clean the outer wall of the water-cooled wall 2, so that the smoke and dust on the inner peripheral surface of the water-cooled wall 2 falls into the furnace cavity, reducing the influence of the smoke and dust on the guiding effect of the outer side of the water-cooled wall 2, so that the heat conduction effect of the water-cooled wall 2 is always maintained at a better effect.

[0032] Please see the attached Figure 5 The bottom ends of several scrapers 67 are fixedly connected with connecting rings 68. A groove is provided at the bottom of the water-cooled wall 2. The connecting ring 68 is arranged inside the groove. The top of the gear ring 4 66 is fixedly connected with an annular shielding cover 69. The bottom end of the outer side of the shielding cover 69 is rotatably connected to the upper surface of the water-cooled wall 2.

[0033] Specifically, the groove is used to accommodate the connecting ring 68, and the connecting ring 68 is used to connect the bottom end of the scraper 67 to improve the stability of the connection of the scraper 67. The shielding cover 69 is used to shield the gear ring three 65 and the gear ring four 66 to prevent smoke and dust from falling into the tooth groove.

[0034] Please see the attached Figure 6 -Attached Figure 7The scraper 67 includes a mounting frame 671. There is a certain gap between the inner wall of the mounting frame 671 and the inner wall of the water-cooled wall 2. The inner wall of the mounting frame 671 is provided with a mounting groove. The inner wall of the mounting groove is rotatably connected to a cleaning plate 672 via a rotating shaft. The side wall of the cleaning plate 672 is rotatably connected to a rotating frame 673 via a rotating shaft. The other end of the rotating frame 673 is rotatably connected to a slide plate 674 via a rotating shaft. The side wall of the slide plate 674 is slidably connected to the inner wall of the mounting groove. The cleaning plate 672 is installed on the front side of the rotating frame 673 in the rotation direction of the scraper 67.

[0035] Specifically, when the scraper 67 rotates, the resistance exerted by the air on the slide plate 674 causes the slide plate 674 to slide close to the cleaning plate 672, and the cleaning plate 672 is pushed by the rotating frame 673 to rotate against the water-cooled wall 2, thereby achieving the function of cleaning the water-cooled wall 2.

[0036] Please see the attached Figure 7 The side wall of the slide 674 is fixedly connected with a flexible connecting piece 675, such as a ceramic fiber rope or a nickel-chromium alloy wire rope, and the other end of the connecting piece 675 passes through the mounting frame 671 and is fixedly connected with a counterweight block 676. The gravity of the counterweight block 676 is less than the resistance exerted by the air on the slide 674 when the scraper 67 rotates.

[0037] Specifically, when the scraper 67 stops rotating, the weight of the counterweight block 676 applies a downward pulling force to the connecting member 675, causing the connecting member 675 to pull the slide plate 674 to slide away from the cleaning plate 672, and drive the cleaning plate 672 to rotate toward the inside of the installation groove through the rotating frame 673 so that it no longer contacts the inner wall of the water-cooled wall 2, thereby avoiding affecting the heat conduction effect of the conflicting area when the cleaning plate 672 presses against the water-cooled wall 2 after cleaning is completed.

[0038] Please see the attached Figure 4 The liquid inlet end 3 includes a liquid inlet pipe 31, one end of which is fixedly provided with a diverter pipe 32, and the upper and lower sides of the diverter pipe 32 are respectively fixedly provided with a delivery pipe 1 33 and a delivery pipe 2 34 connected to the furnace 1, a solenoid valve 1 35 is fixedly provided on the surface of the delivery pipe 1 33, and a solenoid valve 2 36 is fixedly provided at the center of the diverter pipe 32.

[0039] Specifically, water is input through the liquid inlet pipe 31. When cleaning is required, the solenoid valve 1 35 is opened and the solenoid valve 2 36 is closed. The water flows into the water-cooled wall 2 through the delivery pipe 1 33 and drives the driving blade 64 to rotate, thereby achieving the cleaning effect. When cleaning is stopped, the solenoid valve 1 35 is closed and the solenoid valve 2 36 is opened, so that the water flows into the water-cooled wall 2 through the delivery pipe 2 34, and no longer drives the driving blade 64 to rotate, so that the spiral blade 5 and the scraper 67 stop rotating. Since the water-cooled wall 2 needs to be cleaned only after running for a long time, when the water flow is delivered through the delivery pipe 2 34 at this time, the wear of the spiral blade 5 and the cleaning plate 672 can be reduced when the device is in use, thereby extending the service life of the two.

[0040] Please see the attached Figure 8 -Attached Figure 10 A filter assembly 9 for filtering scale is installed at the liquid outlet end 7. The filter assembly 9 includes a cylinder 901. The lower side wall of the cylinder 901 is fixedly connected to the liquid outlet end 7. A return end 10 is fixedly provided at the center of the cylinder 901. The return end 10 is higher than the gas outlet end 8. A partition layer 902 is fixedly connected to the interior of the cylinder 901. A lower connecting rod 903 is provided through the surface of the partition layer 902. The bottom end of the lower connecting rod 903 is fixedly connected to a filter cartridge 904. The top of the lower connecting rod 903 is fixedly connected to an I-shaped upper connecting rod 905. The top of the upper connecting rod 905 passes through the top of the cylinder 901 and the bottom end of the diversion pipe 32.

[0041] Specifically, when cleaning is stopped, the solenoid valve 2 36 is in the open state, and the water flows to the lower area of the diversion pipe 32. The impact force of the water flow on the top of the upper connecting rod 905 pushes the upper connecting rod 905, the lower connecting rod 903 and the connected filter cartridge 904 to descend, so that the filter cartridge 904 descends and is staggered with the liquid outlet end 7, avoiding the filter cartridge 904 affecting the flow rate of the water flow in the cylinder 901, so that the water flow can flow back to the pool more smoothly through the return end 10.

[0042] Please see the attached Figure 8 -Attached Figure 10 The outer wall of the lower connecting rod 903 is provided with an elastic member 907, which can be a leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc. In this embodiment, a fatigue-resistant coil spring made of stainless steel is used. The elastic member 907 is located above the partition layer 902, and the outer wall of the upper connecting rod 905 is provided with a connecting pipe 11. The two ends of the connecting pipe 11 are fixedly connected to the top of the cylinder 901 and the bottom end of the diversion pipe 32 respectively.

[0043] Specifically, the connecting pipe 11 can avoid the problem of water leakage at the penetration point between the upper connecting rod 905, the cylinder 901 and the diversion pipe 32. At the same time, a sealing structure can also be set at the penetration point between the upper connecting rod 905, the cylinder 901 and the diversion pipe 32 for sealing. During cleaning, the solenoid valve 2 36 is in a closed state, and the water does not flow to the lower area of the diversion pipe 32. The impact force exerted on the upper connecting rod 905 disappears, and the elastic member 907 can push the upper connecting rod 905 upward, and drive the lower connecting rod 903 and the connected filter cartridge 904 to rise, so that the top of the filter cartridge 904 moves close to the partition layer 902. At this time, when the water flows out through the liquid outlet 7, it needs to be filtered by the filter cartridge 904 to filter the cleaned scale before it can flow out from the return end 10. The filter cartridge 904 can avoid or reduce the outflow of scale, thereby achieving the effect of collecting scale.

[0044] Please see the attached Figure 8 -Attached Figure 10 The center of the filter cartridge 904 is rotatably connected to a drainage tube 909, the inner bottom wall of the drainage tube 909 is fixedly provided with a limiting protrusion, the upper inner wall of the drainage tube 909 is fixedly connected to an impeller 910, the lower outer wall of the drainage tube 909 is fixedly connected to a T-shaped nozzle 911, the outer wall of the nozzle 911 is fixedly connected to a cleaning piece 912, the bottom end of the cylinder 901 is open, and the bottom end of the cylinder 901 is threadedly connected to a sealing cover 908, the center of the sealing cover 908 is fixedly connected to an extrusion column 913, the top of the extrusion column 913 is provided with a piston block 914, the piston block 914 is slidably set inside the drainage tube 909, and a number of water-permeable holes are opened on the top of the filter cartridge 904.

[0045] 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 the scale agglomerates falls to the bottom of the filter cartridge 904. When the scale needs to be discharged, the sealing cover 908 is screwed off and the scale falls from the opening at the bottom of the cylinder 901. At the same time, part of the water flow inside the cylinder 901 flows downward through the drainage pipe 909. The water flow pushes the piston block 914 to slide downward. When the water flows through the drainage pipe 909, it drives the impeller 910 to rotate. The impeller 910 drives the drainage pipe 909 to rotate. The drainage pipe 909 drives the nozzle 911 to rotate, so that the water flow can be rotated and sprayed out from the nozzle 911. The scale remaining on the inner wall of the filter cartridge 904 is cleaned, and at the same time, the nozzle 911 drives the cleaning sheet 912 to rotate to scrape off the scale, achieving a double cleaning effect, effectively avoiding or splashing scale residue inside the filter cartridge 904. After cleaning, the sealing cover 908 is reinstalled. At this time, the extrusion column 913 is inserted into the drainage pipe 909 and the piston block 914 is pushed upward, so that the piston block 914 is higher than the connection between the nozzle 911 and the drainage pipe 909, so that the water flow no longer flows downward through the drainage pipe 909, thereby stopping the impeller 910 from rotating, reducing the wear of the cleaning sheet 912, and thus extending the service life.
