Description

Technical Field

[0001] This utility model belongs to the field of desulfurization technology, and in particular relates to an energy-saving and environmentally friendly desulfurization boiler. Background Technology

[0002] According to the published patent CN217016027U, an energy-saving and environmentally friendly desulfurization boiler includes a tank with an air inlet on the side and an exhaust outlet on the top. A heat exchange tube, spirally shaped, is located inside the tank. A first pump body is located outside the tank, connected to a pipe assembly. A water tank is located on the side of the first pump body. The pipe assembly sequentially connects the heat exchange tube, the first pump body, and the water tank. A spraying assembly is located at the top of the tank, and a second pump body is located outside the tank. This design solves the problem that the sprayed absorbent liquid absorbs heat from the high-temperature gas upon contact, a problem that existing desulfurization equipment does not utilize, thus lacking energy efficiency and environmental friendliness. However, it still has the following shortcomings:

[0003] The aforementioned equipment achieves the recovery and utilization of heat from the absorbent liquid during the circulation process, improving the energy-saving effect of the device. However, certain impurities are generated during flue gas desulfurization, which fall onto the filter plate. At this time, the filter plate accumulates a large amount of pollutants, requiring cleaning or replacement. However, in existing equipment, the filter plate is generally fixed with bolts, which makes it difficult to replace the filter plate and greatly increases the downtime of the equipment. Therefore, we propose an energy-saving and environmentally friendly desulfurization boiler. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving and environmentally friendly desulfurization boiler. Through the quick-release mechanism and spraying mechanism, the above-mentioned equipment achieves the recovery and utilization of heat from the absorbent liquid during the recirculation process, thus improving the energy-saving effect of the device. However, certain impurities are generated during flue gas desulfurization, and these impurities fall down onto the filter plate. At this time, the filter plate will accumulate a large amount of pollutants, which requires cleaning or replacement of the filter plate. However, in existing equipment, the filter plate is generally fixed with bolts, which makes it difficult to replace the filter plate and greatly increases the downtime of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an energy-saving and environmentally friendly desulfurization boiler, including a boiler, an inlet fixedly connected to the inner wall of the boiler, an outlet fixedly connected to the top inner wall of the boiler, a water inlet fixedly connected to the inner wall of the boiler, a quick-release mechanism provided on the inner wall of the boiler, and a spraying mechanism provided on the outer wall of the boiler.

[0007] The quick-release mechanism includes several support plates, the outer walls of which are fixedly connected to the inner wall of the boiler. A filter plate is slidably connected to the top outer wall of each support plate. Several guide plates are fixedly connected to the inner wall of the boiler, with their outer walls slidably connected to the inner wall. Several fixing plates are fixedly connected to the outer wall of the boiler, and a bidirectional threaded rod is rotatably connected to the inner wall of each fixing plate. A worm gear is fixedly connected to the outer wall of the bidirectional threaded rod. An L-plate is fixedly connected to the outer wall of the boiler, and a worm is rotatably connected to the inner wall of the L-plate.

[0008] Furthermore, the outer wall of the worm gear meshes with the outer wall of the worm wheel, and the outer wall of the bidirectional threaded rod is threaded with several limiting plates. The inner walls of the limiting plates are slidably connected with guide rods, and the outer walls of the guide rods are fixedly connected with fixing plates II. The outer walls of the fixing plates II are fixedly connected to the outer wall of the boiler.

[0009] Furthermore, the outer wall of the boiler is fixedly connected with several positioning plates, the inner walls of the positioning plates are slidably connected with sliding shafts, the outer walls of the sliding shafts are fitted with springs, and the outer walls of the sliding shafts extend through the inner walls of the fixed plates to the inner walls.

[0010] Furthermore, the spraying mechanism includes a connecting plate, the outer wall of which is fixedly connected to the outer wall of the boiler, a water pump fixedly connected to the inner wall of the connecting plate, a connecting pipe fixedly connected to the bottom output end of the water pump, the outer wall of the connecting pipe fixedly connected to the inner wall of the boiler, a transmission pipe fixedly connected to the inner wall of the end of the water pump away from the connecting pipe, a bend fixedly connected to the outer wall of the end of the transmission pipe away from the water pump, and a plurality of spraying pipes rotatably connected to the outer wall of the bend.

[0011] Furthermore, each of the spray pipes has a nozzle fixedly connected to its inner wall, and a gear fixedly connected to its outer wall.

[0012] Furthermore, the outer wall of the boiler is fixedly connected with several limiting frames, and the outer wall of the boiler is fixedly connected with fixing blocks.

[0013] Furthermore, the inner walls of several of the limiting frames are slidably connected with racks, and the outer walls of the racks are meshed with the outer walls of the gears.

[0014] Furthermore, a plurality of hydraulic rods are fixedly connected to the inner wall of the fixing block, and the bottom output ends of the plurality of hydraulic rods are fixedly connected to the bottom outer wall of the rack.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a bidirectional threaded rod. When the bidirectional threaded rod rotates, it drives two limiting plates to move outward in both directions. When one end of the limiting plate moves outward a certain distance, it contacts and presses against the sliding shaft. At this point, the spring that was originally pressed by the sliding shaft will rebound. The force of the spring rebound will drive the sliding shaft to quickly reset, and the reset sliding shaft will disengage from the filter plate. This releases the limiting effect on the filter plate, allowing the filter plate to be removed from the boiler for cleaning. This achieves the effect of quick installation of the filter plate, ensuring its long-term efficient operation, preventing a decrease in filtration efficiency due to dirt accumulation, and thus improving the desulfurization effect of the boiler.

[0017] 2. This utility model incorporates a curved pipe. Lime water entering the curved pipe flows into the nozzle and is then sprayed. The controller activates a hydraulic rod, which pushes a rack forward. The rack slides through a limit frame, causing a gear to rotate. This rotation, in turn, rotates the spray pipe, which in turn rotates the nozzle along the same trajectory. This achieves the effect of adjusting the spray angle, ensuring the desulfurization liquid is evenly sprayed into the boiler flue gas, ensuring more thorough contact between the flue gas and the desulfurization liquid, and improving the desulfurization reaction efficiency.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Please see Figure 1-5 As shown, this utility model is an energy-saving and environmentally friendly desulfurization boiler, including a boiler 1. The inner wall of the boiler 1 is fixedly connected to a flue gas inlet 101, which allows flue gas to enter the boiler 1 for desulfurization. The top inner wall of the boiler 1 is fixedly connected to a flue gas outlet 102, through which the flue gas after desulfurization is discharged. The inner wall of the boiler 1 is fixedly connected to a water inlet 103, through which lime water used during desulfurization enters the interior of the boiler 1. The inner wall of the boiler 1 is provided with a quick-release mechanism 2, and the outer wall of the boiler 1 is provided with a spraying mechanism 3.

[0029] The quick-release mechanism 2 includes several support plates 201. The outer walls of the support plates 201 are fixedly connected to the inner wall of the boiler 1. The support plates 201 are used to support and limit the parts used later. A filter plate 203 is slidably connected to the top outer wall of the support plates 201. Several guide plates 202 are fixedly connected to the inner wall of the boiler 1. Desulfurized impurities fall onto the guide plates 202 and then onto the filter plates 203 for filtration. The outer walls of the guide plates 202 are slidably connected to the inner wall of the boiler 1. Several fixing plates 204 are fixedly connected to the outer wall of the boiler 1. The inner walls of the fixing plates 204 are rotatably connected to bidirectional threaded rods 205. The fixing plates 204 are used to support and limit the bidirectional threaded rods 205 to prevent them from falling off during use. A worm gear 206 is fixedly connected to the outer wall of boiler 5. An L-plate 207 is fixedly connected to the outer wall of boiler 1. A worm 208 is rotatably connected to the inner wall of L-plate 207. When the worm 208 starts to rotate, it will drive the worm gear 206 to rotate. When the worm gear 206 starts to rotate, it will drive the subsequent parts to rotate. The outer wall of the worm 208 is meshed with the outer wall of the worm gear 206. Several limiting plates 209 are threadedly connected to the outer wall of the bidirectional threaded rod 205. Guide rods 214 are slidably connected to the inner walls of the several limiting plates 209. When the limiting plates 209 start to move, they will slide through the guide rods 214. At this time, the guide rods 214 will limit the limiting plates 209. Fixing plates 213 are fixedly connected to the outer walls of the several guide rods 214. The outer walls of the several fixing plates 213 are fixedly connected to the outer wall of boiler 1.

[0030] Several positioning plates 210 are fixedly connected to the outer wall of boiler 1. Sliding shafts 211 are slidably connected to the inner walls of each positioning plate 210. Springs 212 are fitted onto the outer walls of each sliding shaft 211. When the sliding shafts 211 are compressed, they move, compressing the springs 212. The outer walls of the sliding shafts 211 extend through the inner wall of the fixed plate 204. The spraying mechanism 3 includes a connecting plate 301. The outer wall of the connecting plate 301 is fixedly connected to the outer wall of boiler 1. A water pump 302 is fixedly connected to the inner wall of the connecting plate 301. The connecting plate 301 provides fixed support for the water pump 302, ensuring that the water pump 302 operates smoothly during use. More stable, the bottom output end of the water pump 302 is fixedly connected to the connecting pipe 303, the outer wall of the connecting pipe 303 is fixedly connected to the inner wall of the boiler 1, and the inner wall of the end of the water pump 302 away from the connecting pipe 303 is fixedly connected to the transmission pipe 304. The water pump 302 draws lime water from the boiler 1 through the connecting pipe 303 and then transports it into the transmission pipe 304 for subsequent use. The outer wall of the end of the transmission pipe 304 away from the water pump 302 is fixedly connected to the bend pipe 305, and the outer wall of the bend pipe 305 is rotatably connected to several spray pipes 306. The lime water in the transmission pipe 304 enters the bend pipe 305 and is then sprayed through the nozzle 307.

[0031] Spray nozzles 307 are fixedly connected to the inner walls of several spray pipes 306, and gears 308 are fixedly connected to the outer walls of several spray pipes 306. When gears 308 are driven, they will rotate. When gears 308 start to rotate, they will drive other gears 308 to rotate. Several limiting frames 311 are fixedly connected to the outer wall of boiler 1, and fixing blocks 309 are fixedly connected to the outer wall of boiler 1. Racks 312 are slidably connected to the inner walls of several limiting frames 311. When racks 312 start to move, they will... When the rack 312 slides on the limit frame 311, it will drive the gear 308 to rotate. The outer wall of the rack 312 meshes with the outer wall of the gear 308. Several hydraulic rods 310 are fixedly connected to the inner wall of the fixing block 309. The bottom output end of the several hydraulic rods 310 is fixedly connected to the bottom outer wall of the rack 312. When the hydraulic rods 310 start to run, they will push the rack 312 forward. When the rack 312 starts to move, it will drive the gear 308 to rotate.

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed, the operator first connects the flue gas transmission pipe to the flue gas inlet 101. Then, an appropriate amount of lime water is transferred into the boiler 1 through the water inlet 103. The water pump 302 is then started by the controller. When the water pump 302 starts running, it draws the lime water from the boiler 1 through the connecting pipe 303. The lime water is then transferred through the transmission pipe 304 into the bend pipe 305. The lime water in the bend pipe 305 then enters the nozzle 307 and is sprayed. At this time, the hydraulic rod 310 is activated by the controller. When boiler 1 starts operating, it pushes rack 312 forward, causing rack 312 to slide through limit frame 311. As rack 312 moves, it drives gear 308 to rotate, which in turn drives spray pipe 306 to rotate. This rotation of spray pipe 306 then drives nozzle 307 to rotate along the same trajectory, thus adjusting the spray angle. When flue gas enters boiler 1, it comes into contact with the sprayed lime water, resulting in a chemical reaction that achieves desulfurization. The effect is that the impurities generated during desulfurization will fall downwards onto the guide plate 202, and then onto the filter plate 203 for filtration. The filtered lime water will then be carried to the bottom of the boiler 1 for the next use. After prolonged use, the filter plate 203 will accumulate a large amount of impurities on its surface. At this time, the worm gear 208 will be rotated. When the worm gear 208 starts to rotate, it will drive the worm wheel 206 to rotate. When the worm wheel 206 starts to rotate, it will drive the double-ended threaded rod 205 to rotate. When the double-ended threaded rod 205 starts to rotate, it will drive the two limiting... The position plate 209 moves outward in both directions. When the position plate 209 moves outward a certain distance, it will contact the sliding shaft 211 and squeeze it. At this time, the spring 212, which was originally squeezed by the sliding shaft 211, will rebound. The rebound force of the spring 212 will drive the sliding shaft 211 to quickly reset. After resetting, the sliding shaft 211 will disengage from the filter plate 203 and then contact the limit of the filter plate 203. Subsequently, the filter plate 203 can be pulled out of the boiler 1 for cleaning. After cleaning, the above operation is repeated in the reverse direction to complete the installation.
