Description

The manufacturing apparatus and method for dust collecting plate bundle of electrostatic precipitator

The present invention relates to an apparatus and method for manufacturing an electric dust collector dust collecting plate bundle, and more particularly, using a unit dust collecting plate forming unit to conduct electricity using a triple structure of carbon fiber, glass fiber, and a net-shaped sheet for removing air bubbles. The unit dust collecting plate in the form of a tubular body is molded, and a plurality of the molded unit dust collecting plates are laminated several times in the horizontal and vertical directions and adhered with resin to form a dust collecting plate bundle of a structure in which a plurality of dust collecting plates are arranged in the horizontal and vertical directions. It relates to an apparatus and method for manufacturing an electric dust collector plate bundle capable of increasing the dust collecting efficiency by forming the current resistance value of the dust collecting plate.

Recently, an electric dust collector that uses an electric field generated by high-pressure discharge to remove harmful components such as combustion products and dust contained in the air has been widely used. Such an electric dust collector arranges electrodes adjacent to a dust collecting plate made of a conductive material, and when a strong electric field is formed in the dust collecting plate by the discharge generated between the electrode and the dust collecting plate, harmful substances contained in the air passing through the dust collecting plate by the electric field It sticks to the dust collecting plate and is removed.

The dust collecting plate used for such an electric dust collector has conventionally used a conductive metal plate, but recently a dust collecting plate using FRP, which is light and inexpensive, as well as superior in corrosion resistance and durability compared to a metal plate, is mainly used.

This FRP dust collecting plate is composed of a plurality of FRP boards spaced apart from each other by a predetermined distance and arranged in parallel. Therefore, when the dust collecting plate is mounted inside the main body of the electric dust collector and current is supplied to the electrodes installed inside each dust collecting plate, an electric field is generated on the surface of the FRP board by the electric discharge generated between the electrode and the FRP board, and this By the same electric field, harmful substances contained in the air passing through each dust collecting plate are removed by sticking to the FRP board.

On the other hand, the FRP dust collecting plate is usually manufactured by a drawing method of a material containing carbon having conductivity. When the dust collecting plate is manufactured by a drawing method, the current resistance value of the electrode plate decreases as carbon is contained in the material in powder form. There is a problem that the dust collection efficiency is lowered.
