The application method (working principle) of the application is as follows:
during flue gas filtering treatment, flue gas enters the inner side of the dust remover 1 through the gas inlet pipe 11, the flue gas flow is in an upward flowing state due to the gas pressure of the gas outlet and the inside, the flue gas flow pushes the movable plate 12 to deform upward, the flue gas continuously flows upward through the area between the movable plates 12, simultaneously, compressed gas compressed by the air compressor passes through the shunt pipes 6 and is introduced into the inner side of the vent pipe 7 through the one-way air pressure valve, heat exchange is carried out between the compressed gas and the vent pipe 7, the temperature around the vent pipe 7 is reduced, the flue gas with waste heat is condensed into small water droplets by the lower-temperature vent pipe 7 after passing through the periphery of the vent pipe 7, at the moment, the small water droplets are attached to the bottom end surface of the vent pipe 7, the small water droplets are blown upward by the continuously flowing flue gas, the small water droplets move along the outer sides of the guide rods 14 on the two sides of the vent pipe 7, the small water droplets are further gathered towards the bottom end surface of the movable plate 12, the small water droplets can drop onto the surface of the lower side of the resistance plate 15 until the small water droplets are gathered, the volume of the small water droplets is large enough to resist the thrust force of the flue gas, and the small water droplets continuously condenses continuously, and the small water droplets continuously flows continuously and the water droplets are continuously condensed on the bottom surface and the bottom surface of the small water droplets is formed.
When the filter bag 3 is cleaned, the smoke gas introduced by the air inlet pipe 11 is stopped instantaneously, the one-way air pressure valve is closed by air pressure, the pulse valve is opened instantaneously, meanwhile, the movable plate 12 is not subjected to thrust generated by upward flowing of the smoke gas, the movable plate 12 moves horizontally and elastically restores to the shape of the movable plate 12, further, partial water drops on the bottom end surface of the movable plate 12 are shaken off instantaneously, the dust below is further infiltrated, and after the pulse valve is opened, air on the inner side of the ventilation pipe 7 enters the inner side of the pulse assembly 10 through the air collecting pipe 8 and the transition pipe 9, compressed air in the pulse assembly 10 is introduced instantaneously into the inner side of the filter bag 3, the dust on the surface is shaken off after the filter bag 3 vibrates, the dust on the surface of the filter bag 3 falls down under the action of self gravity, after the dust falls to the position of the movable plate 12, the dust impacts the top end of the fixed plate 4, the top end of the movable plate 12 and the top end of the plate 13, after the dust impacts the top end of the fixed plate 4 and the movable plate 12, the dust drops off the fixed plate 4 and the movable plate 12, the water drops into the side of the movable plate 12 due to impact, the dust drops down from the vibration plate 12, the dust drops down from the top end of the movable plate 12, and the dust drops down from the movable plate 12, and the dust falls down from the top of the movable plate 12, and the dust drops down to the movable plate 12.
