AI Technical Summary

Technical Problem

The plate-type electrode structure in existing dust removal equipment results in uneven distribution of plate current density, forming a corona blind zone, which leads to poor local dust collection effect. In addition, the equipment occupies a large area and the dust removal efficiency is unstable.

Method used

The dust collecting electrode structure and the discharge electrode structure are arranged alternately along the flue gas flow direction. The cathode line and the anode tube are staggered to form an electrode matching mode of one electrode to multiple tubes. Combined with the modular layout and the dust collecting opening design of the anode tube, the electric field network density and space utilization are improved.

Benefits of technology

A high-density electric field network is formed in a limited space, reducing electric field blind spots, improving dust collection efficiency and space utilization, enhancing equipment adaptability, and ensuring long-term stable operation.

Abstract

This application discloses a dust removal device, belonging to the field of electrostatic precipitator technology. The dust removal device includes a housing, at least one row of collecting electrode structures, and at least one row of discharge electrode structures. The collecting electrode structures and discharge electrode structures are located in the flue gas channel of the housing and are alternately arranged along a direction intersecting the flue gas flow direction. The collecting electrode structure includes multiple anode tubes continuously arranged along the flue gas flow direction, and the discharge electrode structure includes multiple cathode wires spaced apart along the flue gas flow direction. Along the flue gas flow direction, the projection of the cathode wire in the target direction lies between the axes of two adjacent anode tubes, and the cathode wire simultaneously forms a dust-collecting electric field with the two adjacent anode tubes. By establishing independent electric fields for both anode tubes simultaneously with the cathode wire, a one-electrode-to-multiple-tube electrode matching mode is achieved, enabling the formation of a high-density electric field network within a limited cross-section, thereby reducing the electric field blind zone. Simultaneously, the closely arranged anode tubes improve space utilization and dust collection efficiency.
