Abstract

The invention relates to the technical field of electric filtration and purification, in particular to a honeycomb electrofilter with a high flow rate. According to the honeycomb electrofilter, a power supply control cabinet is connected with a high pressure generator connected with china bottle pull rods; sleeve insulating boxes are arranged at the top of a cylinder; sleeve insulating pieces and the china bottle pull rods are fixedly connected to form a whole and are fixedly connected with an upper hanging bracket, the upper hanging bracket is connected with a barb corona electrode, both a collecting electrode and the barbed corona electrode are arranged between the upper hanging bracket and a lower hanging bracket, and gas distribution plates are arranged below the lower hanging bracket; and an anti-swing suspension, the barbed corona electrode, the collecting electrode and the gas distribution plates are arranged in the cylinder, a gas inlet is formed in the lower part of one side of the cylinder, a gas outlet is formed in the center of the top of a tar precipitating body, and a tar outlet is formed in the lower part of the cylinder. According to the honeycomb electrofilter, the electrofiltration and purification problems of gas when the air speed of a gas electric field is 3-4 m / s are solved, the steel consumption of an equipment body is reduced, and at the same time, the corona power of the electric field is increased, so that the electrofiltration efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric filtration and purification, in particular to a high-flow rate honeycomb electric filter for performing electric filtration and purification of impurity gases through electrostatic deposition. Background technique [0002] In electrostatic separation and purification, the negative high voltage generated by the high-voltage DC power supply is connected to the corona electrode to form a discharge electrode, which forms an uneven electric field with the grounded anode. When the electric field strength exceeds a certain limit, a corona discharge is generated between the cathode and anode. Ionize the gas flowing in the electric field to generate a large number of free electrons and positive ions. The charged particles are driven to the anode by the Coulomb force in the electric field, and when they reach the surface of the anode, they release the charged charge and settle on the anode plate to comple...
