[0013] Compared with the prior art, the smoke elimination boiler has the following beneficial effects:

[0014] 1. The smoke elimination boiler is provided with a smoke elimination treatment device, specifically, the external air is driven into the boiler by the driving structure, so that the oxygen content in the boiler is increased, the combustion in the boiler is fully carried out, when the flue gas in the boiler enters the smoke elimination tank through the connecting pipe, the flue gas spirally flows downward in the smoke elimination tank by the action of the spiral air flow, at this time, the mist water sprayed by the spray nozzle can fully contact with the flue gas, so that the large particles and the smoke dust can be condensed by water, which is helpful to reduce the smoke dust in the flue gas, thereby facilitating further treatment of the flue gas.

[0015] 2. When the smoke dust in the flue gas is treated, the gas flows upward through the ventilation pipe, in the flow process, the rotation of the connecting shaft is driven by the driving structure, the ventilation pipe is connected by four annular shells, the ports of the uppermost and lowermost annular shells are not closed, and the ports of the middle two annular shells are in a closed state, due to the driving force of the driving structure, the flue gas enters the internal cavity of the connecting shaft through the filter frame and the double-layer filter screen in the D area, then enters the double-layer filter screen in the C area through the communication pipe, and then enters the communication pipe through the other group of double-layer filter screens in the area, and then flows into the double-layer filter screen in the B area, and then sequentially flows into the double-layer filter screen in the other area, until the gas is discharged, the flow force of the flue gas is increased by the communication pipe, the purpose of this is to facilitate the double-layer filter screen to fully filter the components in the flue gas, and the filtering efficiency is improved, the gas in each area can only communicate with the double-layer filter screen in the other area through the communication pipe, so as to be filtered again by the other group of double-layer filter screens in the area and then enter other areas through the communication pipe, thereby realizing four-layer repeated filtration, and the filtering effect is improved, and the harmful gas in the flue gas is effectively adsorbed and filtered.

[0016] 3. In order to further improve the circulation speed of the gas in the annular shell, when the driving structure drives the connecting shaft to rotate, the filter frame will also rotate accordingly. Through the action of the bent plate, when the filter frame rotates, it is affected by the bent plate and starts to rotate through the action of the sealed bearing. It should be noted that only the bending directions of the bent plates in areas A and D are consistent. The bending directions of the bent plates on the right filter frame in area B and the left filter frame in area C are consistent with the bending directions of the bent plates in areas A and B, and the other bending directions are opposite. The purpose of this is that when the bent plate starts to rotate, it will generate centrifugal force, which can accelerate the circulation speed of the gas in the double-layer filter screen. The filter frames with opposite bending directions can easily extract the gas in the double-layer filter screen when rotating, thereby accelerating the circulation speed and improving the processing efficiency.

[0017] Therefore, this boiler solves the problems of low smoke elimination efficiency in existing smoke elimination boilers and the inability to achieve effective smoke elimination and harmful substance purification under the premise of sufficient combustion and without changing the existing filtering structure through the above method.

[0028] The specific working principle in the embodiment is as follows: after the combustion of the fuel in the boiler 20, the driving structure is used to accelerate the entry of the external air, which helps to increase the oxygen content in the boiler 20, thereby helping the fuel to burn completely, reducing the excessive generation of harmful substances such as smoke dust, and reducing the filtering pressure of the smoke elimination treatment structure. At this time, due to the action of the driving structure, the flue gas in the boiler 20 enters the smoke elimination tank 2 through the connecting pipe 6. At this time, since the connecting pipe 6 is arranged at the edge of the surface of the smoke elimination tank 2, a spiral wind direction flow is generated after entering the inside of the smoke elimination tank 2. At this time, the particles and harmful gases in the flue gas can be effectively adsorbed by the action of the spray structure, and then fall into the collection structure along the inner wall of the smoke elimination tank 2. At this time, the treated gas flows upward through the ventilation pipe 10. In the flow process, it should be noted that the ventilation pipe 10 is connected by four circular ring shells. The ports of the uppermost and lowermost circular ring shells are not closed, and the ports of the middle two circular ring shells are in a closed state. A circular ring plate with openings is installed at the lower end of the ventilation pipe 10, which helps the gas to enter the D area. In addition, a bearing seat is installed on the circular ring plate, and the connecting shaft 11 is connected to the bearing seat, which facilitates the rotation of the connecting shaft 11 and the stability during rotation. At this time, the flue gas enters the communication pipe 19 through the double-layer filter screen 15 in the D area, and then flows into one of the double-layer filter screens 15 in the C area. The gas is then filtered by the double-layer filter screen 15 in the same area and then flows into the B area and the C area. The gas is then discharged by the driving structure, thereby achieving layer-by-layer filtration. In addition, the diameter of the communication pipe 19 is small, which is to accelerate the flow speed of the gas and increase the flow force of the flue gas. This is to facilitate the rapid filtration of the components in the flue gas by the double-layer filter screen 15, thereby improving the filtration efficiency. The double-layer filter screen 15 in the D area is an activated carbon filter layer, which helps to adsorb SO and SO2. The double-layer filter screen 15 in the C area is an activated carbon composite material formed by combining zeolite and alumina, which helps to adsorb CO2. The double-layer filter screen 15 in the B area is an activated carbon composite material with a high specific surface and a high void ratio, which can effectively adsorb CO. The double-layer filter screen 15 in the A area is the same as that in the B area. The above-mentioned smoke elimination boiler solves the problems of low smoke elimination efficiency and inability to effectively eliminate smoke and purify harmful substances under the premise of complete combustion and without changing the existing filtering structure.
