Wet-type electric precipitation cathode wire and wet-type electric precipitator

Abstract

The invention discloses a wet-type electric precipitation cathode wire and a wet-type electric precipitator., and solves the problems that, in the prior art, a rigid polar line discharge effect is poor; dust removal efficiency is low, and the stability of the flexible polar line is poor. The invention has the advantages of convenient installation and the high dust removal efficiency. According tothe specific scheme, the wet-type electric precipitation cathode wire comprises a metal pipe, the metal pipe is provided with a connecting end connected with a wet-type electric precipitation frame, the metal pipe is sleeved with a metal net to increase the contact surface area with flue gas, the two ends of the metal net are fixed to the metal pipe respectively, and the two ends of the metal netare connected with the metal pipe through buckles respectively.

Description

technical field [0001] The invention relates to the field of electric dust removal, in particular to a wet electric dust removal cathode line and a wet electric dust collector. Background technique [0002] The cathode wire has high mechanical strength, is not easy to break, easy to clean, low in cost, and very simple in processing and production. It is suitable for use in new electrostatic precipitators or to modify old electrostatic precipitators. It is connected to high voltage A high-voltage electric field is formed between the cathode line of the DC power supply and the grounded anode plate. Due to the corona discharge of the cathode, the gas is ionized, and the negatively charged gas ions move toward the anode plate under the action of the electric field force, and are in contact with dust particles during the movement. When they collide, the dust particles will be negatively charged. Under the action of the electric field force, the charged dust particles will also mo...

AI Technical Summary

Problems solved by technology

Due to the material characteristics, the discharge effect between the pole line of the round tube and the anode tube is poor; the discharge effect of the serrated pole line is general, and it needs to be rotated during installation to form a sawtooth shape. It is only suitable for lead materials, and the serrated pole made of stainless steel and titanium is used It is difficult to rotate the wire for several weeks during installation; the discharge effect of the diamond-shaped pole wire is poor; the wire with triangular thorns can only be made of stainless steel and titanium, and the discharge effect is poor; high rate

[0004] The above-mentioned round tubes with prickly shape, rhombus shape and triangular thorn shape are steel pole lines, and flexible serrated and silky flexible pole lines are flexible pole lines. Both steel pole lines and flexible pole lines have certain disadvantages. The rigidity of the polar line is better, but due to the existence of acupuncture, the cathode line has a blank area at the acupuncture point, and the smoke short circuit occurs here, the dust removal efficiency is poor, and the corresponding demisting effect is not good

Although the flexible polar line has a certain improvement in the dust removal effect, the demisting effect is poor, because the flexible polar line is not easy to fix, and it is easy to swing when the wind speed is too high without rigidity. Flexible poles have a shorter service life
