The specific working principle of the invention in the implementation process is as follows:

when the operation is not started, the processing liquid tank 5 is filled with processing liquid which reacts with sulfur-containing and nitrate-containing flue gas, the lower pretreatment layer 8035 and the lower pretreatment layer 8038 are filled with processing agents which can absorb sulfur-containing and nitrate-containing flue gas, and the mesh bags 702 which are respectively distributed on the near-end inner arc 7011 and the far-end outer arc 7012 of the curved sheet 701 are in a hanging state under the action of normal gravity, namely, the fixing pieces 7021 and the fixing plates 704 at the left and right ends of the mesh bags 702 are fixed on the surface of the curved sheet 701 and hung on the tail end and the bottom end of the alloy high-pressure rod 703 or the curved sheet 701 under the action of gravity, meanwhile, the first through grooves 7041 and the second through grooves 704 on the mesh bags 702 are respectively in a state of being blocked by the flexible plates 7043 and the flexible balls 7052, namely, the flexible plates 7043 at the inner ends of the first through grooves 7041 on the fixing plates 704 are tightly attached to the inner walls of the first through grooves 7041, and the flexible balls 7052 at the inner ends of the second through grooves 705 on the surface layer of the mesh bags 702 are tightly attached to the interiors of the second through grooves;

when the dust remover starts working, the device is connected to an external power supply, then flue gas containing sulfur, nitre and needing dust removal is introduced into a dust removing chamber 301 at the lower end in an electric dust removing box 3 through an air inlet pipe 1, meanwhile, a fan 2 is started to accelerate the entry of the flue gas, air flow blown in from left to right drives a plurality of curved sheets 701 in the dust removing chamber 301 to rotate anticlockwise on a rotating shaft 7, impurity particles in the flue gas in the dust removing chamber 301 are respectively thrown onto the outer surfaces of fixing plates 704 on mesh bags 702 at the respective tail ends respectively along inner arcs 7011 and outer arcs 7012 on the curved sheets 701 under the action of centrifugal force when contacting the surfaces of the curved sheets 701, meanwhile, the impurity particles have high impact force due to high speed, enter along first through grooves 7041 on the fixing plates 704 and impact the flexible plates 7043, the flexible plates 7043 embedded at the inner ends of the first through grooves 7041 have certain toughness, so that the impurity particles impacted at high speed leave gaps, the particles can quickly enter the inertia through the gaps, the process is that the impurity particles enter the inner ends of the mesh bags 7043 after the impurity particles enter the initial through gaps, the initial through grooves, the impurity particles can be stopped, and the gaps, the impurity particles can be quickly blown out of the gaps, and the gaps, the impurity particles can be stopped in the first through grooves 7041;

at this time, because the rotating mesh bag 702 also has a faster speed, when the surface of the mesh bag is in contact with the impurity particles in the dust removal chamber 301, a high-speed impact condition also exists, the impurity particles enter along the second through groove 705 on the outer surface of the mesh bag 702 and impact the flexible ball 7052, the flexible ball 7052 embedded at the inner end of the second through groove 705 has certain toughness so as to be ejected out of a gap by the impurity particles under the high-speed impact, at this time, the impurity particles enter the mesh bag 702 through the gap by inertia, the process is an instant process, after the impurity particles enter, the flexible ball 7052 is quickly returned to the initial position to close the gap by the toughness, the second through groove 705 is blocked, and the mesh bag 702 in the rotating and swinging process is prevented from running out of the mesh bag 702 through the second through groove 705 on the surface of the mesh bag 702;

the impurity particles collected in the mesh bag 702 are rubbed with the surface of the mesh bag 702 to have charges of the same polarity, and the alloy high-voltage rod 703 is arranged in the mesh bag 702 in advance, so that the impurity particles after being electrified can be strongly adsorbed on the surface of the high-insulation alloy high-voltage rod 703 after being rubbed with the mesh bag 702 to generate static electricity and enter the mesh bag 702, for example, the static electricity principle that paper scraps can be adsorbed by using a ruler after being rubbed is used, so that the impurity particles are jointly contained and collected with the first through groove 7041, the second through groove 705 and the surface of the mesh bag 702 after being sealed, and the sufficient collection of impurities is further ensured;

because the adsorption filter layer 8 is arranged in the ascending channel of the gas in the electric dust removal box 3, and the through holes 803 which are distributed in a staggered manner are arranged in the adjacent baffle 801 of the adsorption filter layer 8, the gas which is driven to ascend by the counterclockwise rotation of the curved sheet 701 in the dust removal chamber 301 is blocked by the baffle and then flows back to the curved sheet 701 to continue impurity removal, and the gas which ascends to enter the through holes 803 can be temporarily retained by the through holes 803 which are staggered left and right respectively, at the moment, the gas in the through holes 803 respectively drives the lower fan blades 8034 and the upper fan blades 8037 at the right lower end and the left upper end to blow to the lower pretreatment layer 8035 and the upper pretreatment layer 8038 for desulfurization and denitrification pretreatment, and the gas and the lower filter screen 8031 and the upper filter screen 8032 together assist in impurity removal, so that the curved sheet 701 which rotates at the lower end of the adsorption filter layer 8 is prevented from quickly guiding the gas into the diversion chamber 302 for pretreatment, and the purification efficiency is improved for the humidification, desulfurization and denitrification of the later spray head 401;

when the gas subjected to dust removal pretreatment enters the flow guide chamber 302 through the adsorption and filtration layer 8, the gas is converged to the gas guide port along the bend 3021 and enters the desulfurization and denitrification box 4, at the moment, the rotation of the spray header 401 is started to throw the treatment liquid in the treatment liquid tank 5 into the flue gas in the desulfurization and denitrification box 4, the reaction area is enlarged, and the flue gas containing sulfur and nitrate is discharged through the exhaust pipe 6 after being fully purified by a wet method to reach the emission standard;

after the flue gas desulfurization, denitrification and dust removal are finished, the operation of the spray header 401, the alloy high-pressure rod 703 and the fan 2 is stopped, then the equipment is disconnected to an external power supply, then the adsorption and filtration layer 8 is taken out through the grabbing handle 804 to be cleaned and replaced, then the equipment is returned, and then the mesh bags 702 on the curved sheets 701 are taken out, the impurity particles in the mesh bags are cleaned and returned;

in the working process of the invention, the insulating tube of the alloy high-pressure rod 703 is made of epoxy phenol laminated glass resin through hot pressing (has very high mechanical strength and electrical property, and has the characteristics of bending resistance, impact resistance, high insulating property and the like), the fixing part 7021 and the fixing plate 704 on the mesh bag 702 are fixedly arranged inside the surface layer of the curved sheet 701 and cannot be thrown away in the rotation of the curved sheet 701, and the adsorption filter layer 8, the electric dust removal box 3 and the desulfurization and denitrification box 4 are all made of corrosion-resistant materials.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to practitioners skilled in this art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
