In this embodiment, as shown in fig. 1 to 2, the environment-friendly boiler flue gas purification treatment device further includes a smoke exhaust pipe 12; one end of the smoke exhaust pipe 12 is communicated with the incinerator 1, and the other end is communicated with the purifying device shell 21.
When the incinerator 1 works, high-temperature flue gas generated in the incineration process is guided into the purifying device shell 21 through the smoke exhaust pipe 12, and because the temperature difference between the high-temperature flue gas and outside air is large, airflow from top to bottom is generated in the purifying device shell 21. In the purifier housing 21, as the high temperature flue gas passes along with the air flow, the dust entrained by the high temperature flue gas is blocked by the filter screen 41 and stays on the filter screen 41, a part of the air flow is guided into the collecting cavity 22 by the conical surface of the filter screen 41, and a part of the dust is discharged into the collecting cavity 22 along with the air flow. The other part of the air flows through the filter holes on the filter screen 41 and is collected on the power fan blade 52 along the diversion cover 51 and acts on the power fan blade 52. The power fan rotates counterclockwise on the rotating table of the supporting frame 54 through the conical block under the action of the air flow, and the flow speed of the air flow in the guide pipe 13 becomes fast, so that the rotating speed of the power fan becomes fast. Meanwhile, the arrangement of the offset holes can reduce the contact area between the sewage discharge fan blades 31 and the air flow, so that the resistance of the sewage discharge fan blades 31 to the air flow is reduced. The air flow acts on the offset plate 32 through the offset hole to provide a counterclockwise driving force for the dirt discharging fan blade 31, and the counterclockwise driving force is offset from the clockwise driving force applied to the dirt discharging fan blade 31. The dirt accumulated on the filter screen 41 is scooped up by the dirt discharge fan 31 rotating counterclockwise, and falls into the collection chamber 22 along with the rotation of the airflow and the dirt discharge fan 31, and the airflow is discharged from the flow guide pipe 13.
Along with the high-temperature flue gas continuously passes through the dust removal purification device, part of dust is directly and rotatably extruded into the collection cavity 22 by the dirt discharge fan blades 31 in the falling process. Because the burning process produces and can produce great dust, great dust can fall on the filtration pore along with the air current, leads to the dust on the filter screen 41 to constantly increase, and the efficiency of passing through of air current becomes lower, and the air current pressure that receives above the filter screen 41 becomes big, leads to the downward movement, and the bullet strip 42 on the filter screen 41 goes towards vertical state and carries out the power of accumulating. The power fan blade 52 is deformed by the pressure of the filter screen, the inclination angle of the power fan blade 52 is reduced, and the area of the airflow acting on the power fan blade 52 is increased, so that the rotating speed of the power fan is increased, the pollution discharge fan is influenced by larger torsion, and the dust blocking the filter holes on the filter screen 41 is cleaned and discharged to the collection cavity 22. After the filter holes are cleaned, the elastic strip 42 releases the stored force to reset the filter screen 41.
After the incineration of the incinerator 1 is completed, the collection chamber 22 is opened, and the dust in the collection chamber 22 is cleaned.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
