Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as Figure 1-2 Shown: a spiral cathode wire for electrostatic precipitator, including a sheet-shaped cathode wire body 1 with a thickness of 1 to 3mm, the two ends of the cathode wire body 1 are respectively made into connecting pieces 6 so that the cathode wire The cathode wire body 1 is fixed on the cathode frame through the connecting piece 6. The cathode wire body 1 is folded along its length direction into a Z-shaped section in the width direction and then twisted into a spiral shape. The spiral part of the cathode wire body 1 is provided with The discharge tip 2 is pointed, and the angle of the discharge tip 2 is 30°-75°. The cathodic wire body 1 is composed of a middle piece 3, an upper piece 4 and a lower piece 5 after being folded into a zigzag shape. The discharge tip 2 is continuously arranged on the outer edge of the sheet 4 an...

Abstract

The invention discloses a spiral cathode wire for an electrostatic precipitator. The spiral cathode wire comprises a cathode wire body (1), wherein the cathode wire body (1) is formed by folding a sheet body along the length direction into a body with a Z-shaped section in the width direction and then twisting the body with the Z-shaped section into a spiral body, and a sharp-corner-shaped discharge sharp end (2) is arranged on the spiral part of the cathode wire body (1). The cathode wire body is formed by folding the sheet body along the length direction into the body with the Z-shaped section in the width direction and then twisting the body with the Z-shaped section into the spiral body and the sharp-corner-shaped discharge sharp end (2) is arranged on the spiral part of the cathode wire body (1), so that the cathode wire has the characteristics of low corona voltage and high discharge current, is capable of changing gas into a turbulent flow by means of a baffling channel on the cathode wire body to increase thrust of the gas towards a dust collecting electrode, and facilitates the acting of electric field force; dust collected by the cathode wire is difficult to adhere and convenient to clean; the cathode wire has the characteristics of being simple in structure, easy to manufacture and install, and suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel spiral cathode wire for electrostatic precipitators with high efficiency, simple structure and easy manufacture and installation. Background technique [0002] The cathode wire is one of the core components of the electrostatic precipitator, and the structure of the cathode wire directly affects the dust removal and mist removal efficiency of the electrostatic precipitator. At present, the cathode wires of electrostatic precipitators are mostly star-shaped wires, zigzag wires, and ordinary prickly wires, etc., with low current density, corona dead zone, and unsatisfactory dust and fog removal effects. Contents of the invention [0003] The object of the present invention is to solve the problems existing in the prior art, and provide a novel high-efficiency, simple-structured, easy-to-manufacture and install spiral cathode wire for an electrostatic pre...
