Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature slag energy recovery and utilization, in particular to a boiler high-temperature bottom slag cooling and waste heat recovery device. Background Art

[0002] The slag cooler, also known as the slag cooler, is mainly composed of a cylinder, a slag inlet box, a slag outlet box, a power transmission device, a base frame and an electrical control system. It is generally divided into a drum slag cooler, a vibration slag cooler and a water-cooled slag cooler. At present, the most commonly used slag cooler for circulating fluidized bed boilers in China is the drum slag cooler.

[0003] For example, the "vertical multi-layer slag cooler" with the publication number CN103759256A includes a buffer slag flow channel, a slag sweeping plate, a slag cooling plate, and a high-pressure gas nozzle. The buffer slag flow channel and the slag cooling plate are fixed to the outer cylinder wall, the slag sweeping plate is fixed on the central rotating shaft, the slag sweeping plate and the slag cooling plate are repeatedly arranged in multiple layers, and the high-pressure gas nozzle is arranged on the central rotating shaft. Four slag sweeping plates are evenly and symmetrically arranged along the circumference of the central rotating shaft on each layer, and the slag dropping ports of the slag cooling plates are staggered, and buffer inclined plates are provided at the slag dropping ports. The solid slag flows into the slag cooling plate through the buffer slag flow channel, falls layer by layer under the action of the slag sweeping plate, and finally flows out from the slag discharge channel after being fully cooled. The cooling effect is greatly improved, the slag discharge temperature is reduced, and it has a certain anti-slagging ability.

[0004] In the existing technology, although this type of slag cooler can reduce the slag discharge temperature and has a certain anti-slagging ability, it is lacking in waste heat recovery and slag cooling. Since this type of slag cooler does not have a structure to prevent slag accumulation and waste heat recovery, this will result in the slag being unable to fully contact the cooling slag plate due to the accumulation of slag when cooling the boiler slag, and the slag cannot be fully cooled, resulting in heat loss and inability to be fully collected. At the same time, when the staff handles the cooled slag, the slag is not fully cooled, causing burns to the staff. Utility Model Content

[0015] A method for using a boiler high-temperature bottom ash cooling and waste heat recovery device comprises the following steps:

[0016] S1. When the boiler bottom ash needs to be cooled, the motor A is used to drive the shaft to rotate, and the shaft A will drive the slag cooling plate A and the slag cooling plate B to rotate. At this time, the water pump A is turned on, and the water pump A will inject the water in the water tank A into the water inlet grooves of the slag cooling plate A and the slag cooling plate B through the connecting groove A via the connecting pipe A. As the slag cooling plate A rotates, the slag cooling plate A will transport the bottom ash to the discharge port A through the guide groove. At this time, the bottom ash will fall to the top surface of the slag cooling plate B. At this time, the water in the slag cooling plate A and the slag cooling plate B will absorb the heat of the bottom ash. After the absorption is completed, it will be discharged to the water outlet pipe through the water outlet groove and the connecting groove B, thereby completing the cooling of the bottom ash and recovering the waste heat;

[0017] S2. When the bottom ash needs to be crushed and screened, it only needs to be placed on the conveyor belt, which will then transport it to the guide plate. The guide plate will then guide the bottom ash to the crushing roller for crushing. The crushed bottom ash will be screened by the screening plate and then discharged into the cooling box through the feed port, thus completing the crushing and screening of the bottom ash. When the screening plate needs to be cleaned, it only needs to be rotated. After the block slides off the surface of the screening plate, the screening plate can be removed from the crushing box.

[0018] S3. After the conveyor belt transports the bottom slag to baffle A, baffle A rotates in the crushing box via rotating rod A. When the bottom slag moves away from baffle A, baffle A rotates again due to the torsion force of torsion spring A, thus completing the closing of the crushing box. At this time, water pump B is turned on. Water pump B transports water in water tank B to the atomizing nozzle through connecting pipe B. The atomizing nozzle then sprays the bottom slag being crushed, thereby preventing dust from being raised during the crushing process.

[0019] S4. After the bottom ash is cooled, it will fall into the discharge trough of the base, and the rotating shaft will also drive the scraper B to scrape the bottom ash when it rotates. At this time, turn on the motor B, and the motor B will drive the reciprocating screw to rotate. When the reciprocating screw rotates, it will drive the limit rod to slide in the limit groove, and then the limit rod will drive the scraper A to scrape the bottom ash in the discharge trough. When the scraper A moves, it will drive the guide rod to move. After the guide rod moves to the baffle B, it will drive the baffle B to rotate. After the baffle B is turned open, the bottom ash can be scraped out through the scraper A. After the guide rod is away from the baffle B, the baffle B will be rotated by the torsion of the torsion spring B, thereby closing the discharge trough.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The motor A drives the shaft to rotate, and the shaft A drives the cold slag plate A and the cold slag plate B to rotate. At this time, the water pump A is turned on, and the water pump A injects the water in the water tank A into the water inlet trough of the cold slag plate A and the cold slag plate B through the connecting groove A through the connecting pipe A. As the cold slag plate A rotates, the cold slag plate A transports the bottom slag to the discharge port A through the guide groove. At this time, the bottom slag will fall to the top surface of the cold slag plate B. At this time, the water in the cold slag plate A and the cold slag plate B will absorb the heat of the bottom slag. After the absorption is completed, it will be discharged to the outlet pipe through the outlet trough and the connecting groove B, thereby completing the cooling of the bottom slag and recovering the waste heat, thereby avoiding the situation where the slag cannot be completely cooled due to the accumulation of slag during cooling.

[0022] 2. The slag is transported to the guide plate by the conveyor belt, and then the guide plate guides the bottom slag to the crushing roller for crushing. The crushed bottom slag will be screened by the screening plate and then discharged into the cooling box through the feed port, thus completing the crushing and screening of the bottom slag. When the screening plate needs to be cleaned, just rotate the block. After the block slides off the surface of the screening plate, the screening plate can be taken out of the crushing box. After the conveyor belt transports the bottom slag to the baffle A, the baffle A will rotate in the crushing box through the rotating rod A. After the bottom slag is away from the baffle A, the baffle A will be rotated by the torsion force of the torsion spring A, thereby completing the closing of the crushing box. At this time, the water pump B is turned on. The water pump B will transport the water in the water tank B to the atomizing nozzle through the connecting pipe B. The atomizing nozzle will then spray the bottom slag being crushed, thereby preventing dust from being raised when the bottom slag is crushed.

[0023] 3. The rotating shaft drives the scraper B to scrape off the bottom slag. At this time, turn on the motor B, and the motor B will drive the reciprocating screw to rotate. When the reciprocating screw rotates, it will drive the limit rod to slide in the limit groove, and then the limit rod will drive the scraper A to scrape off the bottom slag in the discharge chute. The scraper A will drive the guide rod to move when it moves. After the guide rod moves to the baffle B, it will drive the baffle B to rotate. After the baffle B is turned open, the bottom slag can be scraped out through the scraper A. After the guide rod is away from the baffle B, the baffle B will be rotated by the torsion force of the torsion spring B, thereby closing the discharge chute, thereby preventing the dust in the slag from flying out of the base when the slag is discharged.

When the screening plate 208 needs to be cleaned, it is only necessary to rotate the block 209. After the block 209 slides away from the surface of the screening plate 208, the screening plate 208 can be taken out of the crushing box. After the slag is transported to the baffle A212, the baffle A212 will rotate in the crushing box through the rotating rod A210. After the bottom slag is away from the baffle A212, the baffle A212 will be rotated by the torsion force of the torsion spring A211, thereby completing the closing of the crushing box. At this time, the water pump B203 is turned on, and the water pump B203 will transport the water in the water tank B202 to the atomizing nozzle 205 through the connecting pipe B204. The atomizing nozzle 205 will then spray the bottom slag being crushed, thereby preventing dust from being raised when the bottom slag is crushed.

[0040] Example 3: Reference Figure 9-10As shown: a motor B300 is fixedly installed on the side of the base 100, a reciprocating screw 301 is installed on the output end of the motor B300, a limiting groove 302 is provided inside the base 100, a discharge groove 303 is provided inside the base 100, a limiting rod 304 is slidably connected to the limiting groove 302, a scraper A305 is fixedly installed on both sides of the limiting rod 304, a guide rod 306 is fixedly installed on the surface of the scraper A305, and a rotating rod B3 is rotatably connected to the inside of the base 100. 07. A torsion spring B308 is sleeved on the surface of the rotating rod B307, a baffle B309 is fixedly installed on one end of the rotating rod B307, a scraper B310 is fixedly installed on the surface of the rotating shaft 104, the scraper B310 is slidingly connected to the base 100, the baffle B309 is slidingly connected to the base 100, the limiting rod 304 and the reciprocating screw rod 301 are connected by threads, one end of the torsion spring B308 is connected to the side of the baffle B309, and the other end is connected to the inner surface of the base 100.

[0041] In this embodiment, the rotating shaft 104 drives the scraper B310 to scrape the bottom slag when it rotates. At this time, the motor B300 is turned on, and the motor B300 drives the reciprocating screw 301 to rotate. When the reciprocating screw 301 rotates, it drives the limit rod 304 to slide in the limit groove 302. Then, the limit rod 304 drives the scraper A305 to scrape the bottom slag in the discharge trough 303, and the scraper A305 drives the guide rod when it moves. 306 moves, and when the guide rod 306 moves to the baffle B309, it will drive the baffle B309 to rotate. After the baffle B309 is turned away, the bottom slag can be scraped out through the scraper A305. After the guide rod 306 is away from the baffle B309, the baffle B309 will be rotated by the torsion force of the torsion spring B308, thereby closing the discharge chute 303, thereby preventing dust in the slag from flying out of the base 100 when discharging the slag.

[0042] The usage and working principle of this device: When it is necessary to cool the boiler bottom ash, it is only necessary to drive the rotating shaft 104 to rotate through the motor A103, and the rotating shaft 104A will drive the slag cooling plate A105 and the slag cooling plate B106 to rotate. At this time, the water pump A108 is turned on, and the water pump A108 will inject the water in the water tank A107 through the connecting groove A110 into the water inlet groove 117 in the slag cooling plate A105 and the slag cooling plate B106 through the connecting groove A110. As the slag cooling plate A105 rotates, the slag cooling plate A105 will transport the bottom ash to the discharge port A113 through the guide groove. At this time, the bottom ash will fall to the top surface of the slag cooling plate B106. At this time, the water in the slag cooling plate A105 and the slag cooling plate B106 will absorb the heat of the bottom ash. After the absorption is completed, it will be discharged to the water outlet pipe through the water outlet groove 116 and the connecting groove B111, thereby completing the cooling of the bottom ash and the recovery of waste heat.

[0043] When the bottom ash needs to be crushed and screened, the bottom ash only needs to be placed on the conveyor belt 201, and then the conveyor belt 201 will transport it to the guide plate 206, and then the guide plate 206 will guide the bottom ash to the crushing roller 207 for crushing. The crushed bottom ash will be screened by the screening plate 208 and then discharged into the cooling box 101 through the feed port 213, thereby completing the crushing and screening of the bottom ash. When the screening plate 208 needs to be cleaned, it is only necessary to rotate the clamping block 209. After the clamping block 209 slides off the surface of the screening plate 208, the screening plate 208 can be taken out of the crushing box.

[0044] After the conveyor belt 201 conveys the bottom slag to the baffle A212, the baffle A212 rotates in the crushing box via the rotating rod A210. After the bottom slag moves away from the baffle A212, the baffle A212 is rotated again by the torsion force of the torsion spring A211, thereby completing the closing of the crushing box. At this time, the water pump B203 is turned on. The water pump B203 conveys the water in the water tank B202 to the atomizing nozzle 205 through the connecting pipe B204. The atomizing nozzle 205 then sprays the bottom slag being crushed, thereby preventing dust from being raised during the crushing of the bottom slag.

[0045] After the bottom slag is cooled, it will fall into the discharge trough 303 of the base 100, and the rotating shaft 104 will also drive the scraper B310 to scrape the bottom slag when it rotates. At this time, the motor B300 is turned on, and the motor B300 will drive the reciprocating screw 301 to rotate. When the reciprocating screw 301 rotates, it will drive the limiting rod 304 to slide in the limiting groove 302, and then the limiting rod 304 will drive the scraper A305 to the discharge trough 303. 3 is scraped off, and the scraper A305 will drive the guide rod 306 to move when it moves. After the guide rod 306 moves to the baffle B309, it will drive the baffle B309 to rotate. After the baffle B309 is turned away, the bottom slag can be scraped out through the scraper A305. After the guide rod 306 is away from the baffle B309, the baffle B309 will be rotated by the torsion force of the torsion spring B308, thereby closing the discharge chute 303.
