The cooling device 2 cools the ash and flue gas. The ash and flue gas with decreased temperature move along the cooling device 2 into the slag discharge device 3. The slag discharge device 3 discharges the ash, and the flue gas flows along the slag discharge device 3 into the dust removal device 4. After being dust-removed by the dust removal device 4, the flue gas flows out along the air outlet pipe 5. By setting the cooling device 2 to cool the flue gas, it is avoided that the temperature of the flue gas is too high and the dust removal device 4 is damaged. By setting the slag discharge device 3, while dust removal is carried out, the boiler is slag-discharged, which is convenient for treating the pollutants generated by the boiler.
[0023] The cooling device 2 includes a pipeline 21, the outer side of the pipeline 21 is fixedly connected to the outer side of the feed pipe 1, and a circulating water pipe 22 is sleeved outside the pipeline 21. Both ends of the circulating water pipe 22 are fixedly connected with a water storage tank 23. When in use, the ash and flue gas move along the feed pipe 1 into the cooling device 2, and the ash and flue gas move along the pipeline 21 towards the slag discharge device 3. During this period, the water storage tank 23 sends the cold water inside into the circulating water pipe 22, and the cold water flows along the circulating water pipe 22 to the pipeline 21. The water flow exchanges heat with the flue gas to reduce the temperature of the ash and flue gas. The ash and flue gas with decreased temperature flow along the pipeline 21 into the slag discharge device 3. By setting the cooling device 2 to cool the flue gas, it is avoided that the temperature of the flue gas is too high and the dust removal device 4 is damaged. At the same time, the cooling device 2 recovers the heat of the flue gas through the water flow, reducing the waste of energy.
[0024] The slag discharge device 3 includes an air inlet pipe 31, the outer side of the air inlet pipe 31 is fixedly connected to the side of the pipeline 21 away from the feed pipe 1, and a slag discharge assembly 32 is fixedly connected to the bottom of the air inlet pipe 31. The side of the slag discharge assembly 32 away from the air inlet pipe 31 is fixedly connected with a cooling bin 33. When in use, the ash and flue gas with decreased temperature flow along the pipeline 21 into the air inlet pipe 31, the flue gas flows along the air inlet pipe 31 into the dust removal device 4, and the ash moves along the slag discharge assembly 32 into the cooling bin 33. There is cooling water stored in the cooling bin 33, and the cooling water cools the ash. After cooling is completed, the ash is further processed. By setting the slag discharge device 3, the device can carry out slag discharge and dust removal of the boiler at the same time, accelerating the speed of treating the substances generated by the boiler.
[0025] The slag discharging assembly 32 includes a slag discharging pipe 321. The top of the slag discharging pipe 321 is fixedly connected to the bottom of the air inlet pipe 31. One side of the slag discharging pipe 321 away from the air inlet pipe 31 is fixedly connected to the outer side of the cooling bin 33. A blower 322 is fixedly connected to the outer side of the slag discharging pipe 321. A guiding plate 323 is fixedly connected to the inner side of the air inlet pipe 31. During use, the ash slag and flue gas with reduced temperature flow along the pipeline 21 into the interior of the air inlet pipe 31. The ash slag and flue gas are blocked by the guiding plate 323 in the slag discharging assembly 32 and cannot directly pass through the air inlet pipe 31. At this time, the blower 322 is in an open state. The blower 322 drives the air flow to move towards the direction of the guiding plate 323. The flue gas is driven to move upward, passes through above the guiding plate 323, and then flows along the air inlet pipe 31 into the dust removal device 4. Since the ash slag and some larger impurities are larger and have a greater mass, the air flow cannot drive the ash slag to move. Affected by gravity, the ash slag falls downward into the interior of the slag discharging pipe 321. Since the slag discharging pipe 321 is inclined, the ash slag will slide downward along the slag discharging pipe 321. The ash slag moves along the slag discharging pipe 321 into the interior of the cooling bin 33. By setting the slag discharging assembly 32, the ash slag is processed to separate the ash slag from the flue gas, preventing the ash slag from entering the dust removal device 4.
[0026] The dust removal device 4 includes a housing 41. The outer side of the housing 41 is fixedly connected to one side of the air inlet pipe 31 away from the pipeline 21. A sieve plate 42 is fixedly connected to the inner side of the housing 41. An activated carbon plate 43 is fixedly connected to the inner side of the air outlet pipe 5. During use, the flue gas moves upward along the housing 41 to the sieve plate 42. The sieve plate 42 filters the dust in the flue gas. The filtered flue gas flows upward into the interior of the air outlet pipe 5. After the flue gas passes through the filtration of the activated carbon plate 43, it flows along the air outlet pipe 5 to the outside. By setting the dust removal device 4, the flue gas is processed to prevent the flue gas from being directly discharged to the outside, preventing the flue gas from polluting the atmosphere and protecting the health of the staff.
[0027] A connecting pipe 44 is fixedly connected to the top of the housing 41. The bottom of the connecting pipe 44 penetrates through the housing 41 and is fixedly connected to a spray head 45. A drain pipe 46 is fixedly connected to the bottom of the housing 41. During use, the connecting pipe 44 is connected to an external water source. The external water source sends water flow into the interior of the spray head 45 through the connecting pipe 44. The spray head 45 sprays the water flow, and the water flow flushes the sieve plate 42. After the dust removal is completed, the sewage is discharged through the drain pipe 46. By using the water flow to perform backwashing on the sieve plate 42, it is avoided that dust accumulates on the sieve plate 42, affecting the filtering effect of the sieve plate 42. At the same time, the water flow further reduces the temperature of the flue gas, preventing the discharged flue gas from scalding the human body.
[0028] Working principle:
[0029] During use, the ash and flue gas of the boiler are discharged into the feed pipe 1. The ash and flue gas move along the feed pipe 1 into the cooling device 2. The ash and flue gas move along the pipe 21 towards the slag discharging device 3. During this period, the water storage tank 23 sends the cold water inside into the circulating water pipe 22. The cold water flows along the circulating water pipe 22 to the pipe 21. The water flow exchanges heat with the flue gas to reduce the temperature of the ash and flue gas. The ash and flue gas with reduced temperature flow along the pipe 21 into the slag discharging device 3.
[0030] The ash and flue gas with reduced temperature flow along the pipe 21 into the intake pipe 31. The ash and flue gas are blocked by the guide plate 323 in the slag discharging assembly 32 and cannot directly pass through the intake pipe 31. At this time, the fan 322 is in the on state. The fan 322 drives the air flow to move towards the direction of the guide plate 323. The flue gas is driven to move upward, passes through above the guide plate 323, and then flows along the intake pipe 31 into the dust removal device 4. Since the ash and some larger impurities are larger and have a greater mass, the air flow cannot drive the ash to move. Affected by gravity, the ash falls downward into the slag discharging pipe 321. Since the slag discharging pipe 321 is inclined, the ash will slide downward along the slag discharging pipe 321. The ash moves along the slag discharging pipe 321 into the cooling bin 33. The cooling bin 33 stores cooling water, and the cooling water cools the ash. After the ash is cooled, the ash is further processed.
[0031] The flue gas moves upward along the outer shell 41 to the sieve plate 42. The sieve plate 42 filters the dust in the flue gas. The filtered flue gas flows upward into the outlet pipe 5. After the flue gas is filtered by the activated carbon plate 43, it flows along the outlet pipe 5 to the outside. At the same time, the external water source sends water flow into the spray head 45 through the connecting pipe 44. The spray head 45 sprays the water flow, and the water flow flushes the sieve plate 42. After the dust removal is completed, the sewage is discharged through the drain pipe 46.
