Working principle of the dust collector welding workshop

Welding workshop filter working principle of the welding workshop dust catcher is in electrostatic precipitator operating experience and learning advanced technology design, suitable for industrial waste gas purification and useful material recycling. Welding workshop dust purification effect is mainly rely on corona pole and precipitation to complete the two systems. When dusty gases into the air intake bell mouth, dusty gas after exposure to the air distribution plate and the adjustment of the guide plate, the air can be evenly into the electric field. In the expansion, under the action of cross section reduced airflow speed quickly, some of the heavier dust coarse particle will lose speed and settling down. Into the field of dusty air with corona pole into the high voltage direct current (dc), in a relatively stable is formed between cathode and anode high voltage electric field, and the corona pole ( This equipment is the cathode) Corona phenomena (near Discharge) To make into the electric field of dusty gas ionization. After the ionization of gas in the presence of large amounts of electrons and positive and negative ions, the electrons and ions combined with into electric dust, dust charged. Charged dust particles under the action of electric field force, anode (toward this equipment The positive plate) And the cathode ( Cathode) Are attached to the anode, the dust release or negative charges, adherent dust particles on cathode release after a positive charge, deposited on the positive and negative electrodes, respectively. When the dust precipitation to a certain thickness, through the Yin, the anode vibrating system of vibration, the deposition of dust fall, into the hopper, channelled through ash discharging device, recovery of useful materials, purified gas discharged into the atmosphere. Practice proves that the strong electrostatic field of the higher, the better the electric dust catcher and the effect of negative corona dust catcher to. So, this equipment is designed for high voltage negative corona electrode form.
