Abstract

The invention relates to the technical field of cathode systems in industrial electric dust collectors, particularly a cathode wire connector for an electric dust collector. In the connecting mode of a conventional electric dust collector cathode plate, the wire is usually fixed by welding and bolting, the cathode wire can be subjected to temperature distortion, and the linearity and firmness can not be easily ensured; and the mode of suspending a weight on the bottom of the cathode wire can ensure the linearity of the wire, but can not be easily disconnected. The cathode wire connector comprises a cathode wire, a cathode frame and a spring connecting assembly, wherein the spring connecting assembly is composed of a spring, a gasket and a backstop pin; the cathode frame is provided with a through hole; and the cathode wire penetrates through the through hole of the cathode frame, the spring and the gasket, and is locked and fixed by the backstop pin. By using the tensile force of the spring connecting assembly, the invention solves the problems of lost connection, disconnection and the like due to temperature distortion of the cathode wire, prolongs the service life of the cathode system, and ensures the long-term reliable operation and dust collection efficiency of the dust collector.

Description

technical field [0001] The invention relates to the technical field of the cathode system of an industrial electrostatic precipitator, in particular to a cathode wire connection device of an electric precipitator. Background technique [0002] The electrostatic precipitator is an air purification device used to capture dust in the air in a dusty environment. A high-voltage direct current is passed through the cathode line of the electrostatic precipitator, and an electrostatic field is maintained between the cathode line and the anode plate; when the gas containing a large amount of dust passes through the high-voltage electrostatic field, it is ionized to charge the dust particles, and in the Under the action of the electric field force, the charged dust particles move to the anode plate and deposit on the anode plate, the dust particles are separated from the dust-containing gas, and then the anode plate is hit by the vibrating hammer driven by the reducer to make the dust...

AI Technical Summary

Problems solved by technology

[0003] The cathode line is the main device for discharging and capturing dust in the precipitator. Its working status determines the dust removal efficiency of the precipitator. The connection method of the cathode plate of the conventional electrostatic precipitator is usually to weld the connection plate on the frame and use bolts to fix the line body or open holes in the frame. It is fixed by bolt connection. In this connection method, it is difficult to guarantee the straightness and firmness of the cathode line

Especially during the operation of the electrostatic precipitator, the flue gas temperature is high, and the length of the cathode wire is deformed and elongated by heat, resulting in a decline in discharge performance; the unreliable fastening method can easily cause the cathode wire to fall off, and the electric field is separated, which seriously affects the electrostatic precipitator. dust collection efficiency

However, the cathode line of high-temperature electrostatic precipitator adopts the overall long type. In the prior art, the method of hanging the weight at the bottom of the cathode line is used to ensure its straightness. The section of the electrostatic precipitator is large, and the length of the anode wire is more than 8m, the cathode wire needs to have higher rigidity and larger rapping acceleration value, and the cathode wire device should have better rapping force transmission performance to ensure vibration The hitting acceleration value can be evenly distributed to achieve the ideal dust removal effect, but the actual operation results show that due to the limitation of the structure of the cathodic wire hanging weight method, the disconnection phenomenon is often caused by the insufficient strength of the cathode wire

The main reason for this problem is that the rigidity and strength of the cathode wire are not enough due to the long cathode wire, the connection device is unreliable, and the too long cathode wire will affect the transmission of the rapping force and cannot obtain sufficient rapping acceleration. The cleaning effect and service life of the dust collector cannot be guaranteed
