[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1-Figure 4As shown, a novel energy-saving wet electrostatic precipitator anode tube module includes a plurality of anode tubes 3, wherein the anode tubes 3 include a common PP air duct layer 1 and a conductive PP air duct layer 2 sleeved on the inner peripheral wall of the common PP air duct layer 1, wherein the common PP air duct layer 1 and the conductive PP air duct layer 2 are integrated by thermoplastic heating, and a plurality of the anode tubes 3 are connected by thermoplastic heating to form a honeycomb anode tube module 4, wherein a composite fiber layer 5 is attached to the outer peripheral surface of the common PP air duct layer 1, wherein the composite fiber layer 5 is formed by weaving two composite yarns 51 in warp and weft, wherein the composite yarn 51 includes a polyester fiber 511, two polytetrafluoroethylene fibers 512 wrapped on the outer peripheral surface of the polyester fiber 511 and twisted, and a carbon fiber 51 wound around the outer side of the polyester fiber 511 and the polytetrafluoroethylene fiber 512. 3. The ordinary PP duct layer 1 and the conductive PP duct layer 2 are melted together by thermoplastic heating, which maintains the original conductive function. Because the conductive PP reduces the resistance, the corrosion resistance and leakage prevention capabilities are increased. At the same time, the ordinary PP has good strength and can play a supporting role. Through the setting of the composite fiber layer 5, the polyester fiber 511 has good anti-static ability, which can block the influence of external static electricity on the present invention. The polytetrafluoroethylene fiber 512 has the effect of high temperature resistance and can withstand strong acids and alkalis, further enhancing the acid and alkali corrosion resistance of the anode tube. The carbon fiber 513 has a high structural strength, which can enhance the overall service life of the present invention. The cross-section of the anode tube 3 is set as a regular hexagon, which enhances the structural stability of the present invention and saves material costs.

[0018] On the basis of the above, the common PP air duct layer 1 is injection molded from common PP material, and the conductive PP air duct layer 2 is injection molded from conductive PP material.

[0019] On the basis of the above, the wall thickness of the ordinary PP air duct layer 1 is 4.4mm-5.0mm, and the wall thickness of the conductive PP air duct layer 2 is 2.5mm-3.2mm.

[0020] On the basis of the above, the conductive PP air duct layer 2 is carbon black conductive PP, which has the characteristics of stable conductivity, good toughness, strong fluidity, high rigidity and excellent chemical resistance.

[0021] On the basis of the above, the cross-section of the anode tube 3 is a regular hexagon, and a plurality of regular hexagonal anode tubes 3 are arranged to form a honeycomb-shaped anode tube module 4, so that the anode tube module 4 has a compact structure, is not prone to deformation, has high stability, and also has the advantages of small size and small footprint.

[0022] Working principle: During operation, the flue gas passes through the high-voltage electric field in the anode tube module 4. The high-voltage electric field charges the smoke and mist droplets in the flue gas to form charged ions. The charged ions move toward the electrodes of opposite charge. After reaching the electrodes, the charged ions discharge to form neutral dust and mist particles, which are deposited on the electrodes, condensed, and dropped to be removed. During operation, the ordinary PP duct layer 1 has good structural strength, which can enhance the stability of the present invention. At the same time, the conductive PP duct layer 2 arranged inside has excellent conductivity, which allows the smoke and mist droplets to adhere to more charged ions, thereby enhancing the dehumidification and dust removal effect of the present invention.

[0023] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
