Abstract

The invention discloses a demountable nonmetallic FRP electrostatic dust collection device suitable for automatic production. The electrostatic dust collection device is low in cost, light in weight, convenient to assemble, firm, durable, good in dust collection effect, anticorrosive and high-temperature-resistant and can prevent cathode oscillation under high smoke speed. An anode supporting beam and a cathode supporting beam are fixedly arranged in a box; a cathode top supporting pipe and a cathode bottom positioning pipe are arranged on the cathode supporting beam; multiple honeycomb cylinders are arranged on the anode supporting beam and comprise multiple plate members, connecting strips and coamings; a hexagonal-prism-shaped dust collection unit is formed on each honeycomb; cathodes are arranged in cathode sleeve holes in the top supporting pipe and the cathode bottom positioning pipe; cathode carbon fiber layers are arranged on the surface of the cathode top supporting pipe; the connecting strips are connected with the anode supporting beam through FRP angle steel; carbon fiber layers are arranged on the surfaces of the plate members and the connecting strips and the outer side face of the angle steel; an anode carbon fiber layer is arranged at a position, which corresponds to the angle steel, of the anode supporting beam; an anode carbon fiber board is transversely arranged on one side of the anode supporting beam; a cathode carbon fiber board is transversely arranged on the cathode top supporting pipe.

Description

technical field [0001] The invention relates to a detachable non-metallic FRP electrostatic dust collector suitable for automatic production. Background technique [0002] The existing electrostatic dust collection device for power plants is composed of a metal box, an anode support beam, a cathode joist, and a plurality of honeycomb cylinders arranged on the anode support beam. The screw nest cylinder is bonded by a plurality of conductive cylinders Each conductive cylinder is composed of an FRP cylinder and a carbon fiber surface layer wound on the inner wall of the FRP cylinder. The conductive cylinder is used as the anode, and the cathode is inserted into the conductive cylinder during installation, and the flue gas entering the electrostatic vacuum cleaner is electrostatically vacuumed after power-on.

AI Technical Summary

Problems solved by technology

The problems of the electrostatic precipitator with this structure are: complex processing technology, high processing cost, large volume, large space occupation, inconvenient installation, poor strength; metal structure, heavy weight, high basic cost of the box, although the metal beam Anti-corrosion treatment has been done but it is easy to fall off, causing quality accidents

Due to the double wall thickness (16mm) between two adjacent conductive cylinders, the vacuuming space is wasted and the vacuuming effect is not ideal

In addition, when the existing electrostatic vacuum cleaner is used, the cathode is directly inserted into the conductive cylinder, and the cathode is easy to swing under high smoke velocity after being heated or cooled, causing a short circuit between the cathode and the anode.
