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 an annular needle-shaped electric defogging cathode ray. The annular needle-shaped electric defogging cathode ray comprises a cathode bar, terminals, nuts and annular needles and is characterized in that the cathode bar is made of solid circular stainless steel or lead metal, the diameter of the cathode bar is 4-12mm, the length of the bar is 1-8m, the annular needles are arranged on the cathode bar and spaced in parallel by 20-50mm, the height of the annular blade of the annular needle is 2-5mm, the terminals at the two ends of the cathode bar are in thread structures, and nuts for fastening are arranged on the terminals. The annular needles of the electric defogging cathode ray are machined and connected with the cathode bar into a whole body, are very firm, easy to machine and long in running time so that the efficient running of the electric defogging cathode ray is ensured. The annular needle-shaped electric defogging cathode ray has the advantages of multiple electric discharging points, uniform electric discharging and good demisting effect due to the adoption of an annular needle-shaped blade electric discharging structure, as well as good economic benefits, social benefits and ecological benefits.

Description

Technical field: [0001] The invention belongs to the technical field of chemical engineering and environmental protection, and relates to a component of an electric demister, in particular to a ring needle-shaped cathode line for electric demisting. 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 li...
