[0028] A flue gas outlet pipe 11 is installed at the lower part of the processing tank 6, and a smoke exhaust pipe 12 is connected to the top of the boiler body 1. A spiral tube 13 is sleeved on the outer wall of the smoke exhaust pipe 12. The water inlet end and the water outlet end of the spiral tube 13 are respectively threadedly connected with a water inlet pipe 14 and a drain pipe 15. The drain pipe 15 passes through the top of the boiler body 1 and is welded to the furnace 3.
[0029] A dosing tank 16 is provided at one side of the treatment tank 6 . The dosing tank 16 has a built-in pump body. A nozzle 17 is connected to the dosing tank 16 . The nozzle 17 is arranged at the inner side of the treatment tank 6 .
[0030] A moving rod 18 is slidably connected inside the moving sleeve 10, a moving block 19 is connected to the bottom of the moving rod 18, and a moving spring 20 is sleeved outside the moving rod 18. The two ends of the moving spring 20 are respectively in contact with the moving sleeve 10 and the moving block 19.
[0031] A threaded rod 21 is threadedly connected between the air outlet pipe 8 and the movable sleeve 10 , and a guide rod 22 is slidably connected to the other side of the air outlet pipe 8 and the movable sleeve 10 .
[0032] In this embodiment, during the use of this device, water is manually injected into the water injection pipe 4 to flow into the furnace 3, and then the combustion chamber 2 is manually started to heat the water in the furnace 3. When it is heated, the hot gas is discharged along the exhaust pipe 5, and the smoke is discharged along the smoke exhaust pipe 12 and flows into the treatment tank 6. At this time, water is manually introduced from the water inlet pipe 14 and flows along the spiral tube 13 on the outside of the smoke exhaust pipe 12. The heat of the smoke is used to heat the water flow, and the smoke finally flows into the treatment tank 6, and the water flow flows into the boiler body 1. After the smoke enters the treatment tank 6, the water pump in the dosing tank 16 is manually started to introduce the medicine in the dosing tank 16 into the nozzle 17 The smoke is sprayed out at the place where the smoke is sprayed, and the dust therein falls onto the filter plate 7, which filters the smoke and is finally discharged along the smoke outlet pipe 11. When it is necessary to adjust the rate of exhausting the smoke, the threaded rod 21 is manually rotated to drive the movable sleeve 10 to slide along the abutting rod 18, and under the action of the guide rod 22, the movement process is made more stable. After moving to the appropriate position, stop twisting. When the gas is discharged along the bottom of the outlet pipe 8, after the gas reaches a certain pressure, the abutting block 19 is squeezed upward. At this time, under the cooperation of the movable sleeve 10, the redundant abutting spring 20 is compressed, and finally the abutting block 19 is pushed open, so that the gas is finally discharged along the exhaust hole 9.
[0033] See also Figure 5 As a waste heat recovery steam boiler implementation method for the drainage component: a drainage component is installed at the bottom end of the processing tank 6, and the drainage component includes a drain pipe 23, a fixing block 24 and a compression groove 25. The drain pipe 23 is installed on the processing tank 6, the fixing block 24 is installed on one side of the drain pipe 23, and the compression groove 25 is opened on the inner side of the drain pipe 23.
[0034] A moving block 26 is slidably connected to the compression groove 25 . A compression spring 27 is installed on the compression groove 25 . The compression spring 27 abuts against the moving block 26 . A sliding sleeve 28 is fixedly installed on the moving block 26 .
[0035] A sliding rod 29 is slidably connected to the inner side of the sliding sleeve 28 . The sliding rod 29 is connected to the fixed block 24 . A spring sheet 30 is installed between the fixed block 24 and the movable block 26 .
[0036] More specifically, when the medicine in the treatment tank 6 is discharged, it is discharged along the drain pipe 23. During its flow, it impacts the spring sheet 30 to make it open, and due to the fixing process of the fixed block 24, the sliding rod 29 slides inside the sliding sleeve 28, thereby increasing the distance between the fixed block 24 and the moving block 26, thereby increasing the water flow speed. When the water flow speed decreases, due to the action of the compression spring 27 in the compression groove 25, the moving block 26 is driven to move in the direction of the position of the fixed block 24, and the moving block 26 slides on the compression groove 25, and this process is carried out more stably.
[0037] In summary, when the overall equipment is in use or running: during the use of this device, water is manually injected into the water injection pipe 4 to flow into the furnace 3, and then the combustion chamber 2 is manually started to heat the water in the furnace 3. When it is heated, the hot air is discharged along the exhaust pipe 5, and the smoke is discharged along the smoke exhaust pipe 12 and flows into the treatment tank 6. At this time, water is manually introduced from the water inlet pipe 14, and flows along the spiral tube 13 on the outside of the smoke exhaust pipe 12. The heat of the smoke is used to heat the water flow, and the smoke finally flows into the treatment tank 6, and the water flow flows into the inside of the boiler body 1. After the smoke enters the treatment tank 6, the water pump in the dosing tank 16 is manually started to introduce the medicine into the dosing tank 16. It is sprayed to the nozzle 17 to spray the smoke, and the dust therein falls onto the filter plate 7, which filters the smoke and is finally discharged along the smoke outlet pipe 11. When it is necessary to adjust the rate of exhausting the smoke, the threaded rod 21 is manually rotated to drive the movable sleeve 10 to slide along the abutting rod 18, and under the action of the guide rod 22, the movement process is made more stable. After moving to the appropriate position, the twisting is stopped. When the gas is discharged along the bottom of the outlet pipe 8, after the gas reaches a certain pressure, the abutting block 19 is squeezed upward. At this time, under the cooperation of the movable sleeve 10, the excess abutting spring 20 is compressed, and finally the abutting block 19 is pushed open, so that the gas is finally discharged along the exhaust hole 9.
[0038] When the medicine in the treatment tank 6 is discharged, it is discharged along the drain pipe 23. During its flow, it impacts the spring sheet 30 to make it open, and due to the fixing process of the fixed block 24, the sliding rod 29 slides inside the sliding sleeve 28, thereby increasing the distance between the fixed block 24 and the moving block 26, thereby increasing the water flow speed. When the water flow speed decreases, due to the action of the compression spring 27 in the compression groove 25, the moving block 26 is driven to move in the direction of the position of the fixed block 24, and the moving block 26 slides on the compression groove 25, and this process is carried out more stably.
[0039] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
