Problems solved by technology

The disadvantage is that the current density distribution is uneven, and the thorns of this type of cathode wire are radially welded on the steel pipe, which often falls off under the long-term high temperature and strong vibration of the electrostatic precipitator, which seriously affects the dust removal effect
[0008]The advantage of the star-shaped cathode line is that the current density distribution is relatively uniform, and the disadvantage is that the corona initiation voltage is relatively high

Abstract

The invention discloses a spiral needle electric demisting cathode ray which comprises a cathode bar, wiring terminals, nuts and a spiral discharging body. The spiral needle electric demisting cathode ray is characterized in that the cathode bar is made of solid round metal, the interval of spiral tooth blades of the spiral discharging body arranged on the cathode bar is 20-50mm, the interval between the spiral tooth blades of the spiral discharging body and the cathode bar is 2-5mm, the wiring terminals positioned at two ends of the cathode bar are of threaded structures, and the wiring terminals are provided with the fastening nuts. The spiral discharging body of the electric demister cathode ray and the cathode bar are integrally connected, are extremely firm and are easy to process, the running time is long, and efficient running of an electric demister is guaranteed. Besides, a spiral blade discharging structure is adopted, discharging points are many, and the spiral needle electric demisting cathode ray discharges electricity evenly, is good in demisting effect and has good economic benefit, social benefit and ecological benefit.

Description

Technical field: [0001] The invention belongs to the technical field of chemical engineering and environmental protection, and relates to an electric demister component, in particular to a spiral needle electric demisting cathode line. Background technique: [0002] The electrostatic demist (dust) device uses a high-voltage electrostatic purification method to capture mist or dust in the exhaust gas. Its working principle is that after the dusty gas enters the electric field evenly, a corona phenomenon is generated near the corona electrode to ionize the gas. , there are a large number of electrons and ions in the ionized gas, these electrons and ions combine with the mist (dust) entering the electric field to form charged particles, and the charged particles gather at the anode of the electrostatic mist remover (dust) under the action of the electric field And the cathode, under the action of rapping and gravity, slides down, and is discharged through the liquid discharge...
