Coulomb electrostatic precipitator

Abstract

The invention relates to the technical field of a dust removing device, and relates to a Coulomb electrostatic precipitator. The Coulomb electrostatic precipitator comprises a housing body, an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe are respectively arranged at two ends of the housing body. A plurality of ring beams abutted against the inner wall of the housing body are arranged in the length direction in the housing body. The ring beams are connected with each other through connecting rods, and a framework having a rectangular cross section which is internally connected with the ring beams is arranged in the housing body. A dust removing device is arranged on the framework and comprises anode plates arranged on the framework and cathode wires arranged on the framework. The anode plates and the cathode wires are arranged in the housing body in a rectangular array manner. The Coulomb electrostatic precipitator has the following effects:the ring beams can support the housing body to a certain extent; the connecting rods connect all the ring beams into a whole body; the framework internally connected to the ring beams can further increase the overall strength of the housing body; and the framework is capable of carrying out secondary support on the ring breams, so the possibility of heat deformation of the housing body during treatment of high temperature smoke is reduced, and the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a Coulomb electrostatic precipitator. Background technique [0002] During the operation of the pulverized coal pyrolysis device, a large amount of dust is mixed with the pyrolysis gas, which seriously affects the subsequent process. Therefore, advanced dust removal equipment is needed to remove the dust in the flue gas. One of the more effective methods of collecting particles in flue gas is electrostatic precipitator. [0003] The existing electrostatic precipitator includes a casing, the two ends of the casing are respectively provided with an air inlet and an exhaust port, and several electric fields composed of cathode wires and anode plates are arranged in the casing, and vibration cleaning is arranged in the electric field. The device; the gas passes through the cathode line and the anode plate in parallel, and a negative high-voltage direct current is app...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: since the flue gas temperature after pyrolysis of general pulverized coal will reach 500 to 600 ° C, and the frame in the general electrostatic precipitator will become soft when it is in this temperature environment , causing the overall frame to deform in a high-temperature environment, and the degree of deformation will increase after repeated use, which will eventually cause the equipment to be unusable and have a shorter service life
