Description
Technical Field
The utility model particularly relates to a plate-type oil smoke electrostatic field collected by a multi-stage high-voltage tail end belt filter tank.

The fume purifying equipment mainly applies DC high voltage to the internal electrostatic field, and the electric discharge of the cathode needle of the electrostatic field makes the fume particles pass through attach electricity, and the negatively charged fume particles are adsorbed onto the dust collecting plate with opposite polarity under the action of the coulomb force of the electrostatic field. In practical application, a part of the oil smoke particles are not electrified, and the other part of the oil smoke particles are not completely adsorbed on the dust collecting plate even if the oil smoke particles are electrified, or are blown away from the plate under the action of wind force after being adsorbed on the plate, so that the oil smoke particles are not effectively intercepted to cause the escape of the oil smoke, and the oil smoke particles are mainly influenced by wind speed, the self quality of the oil smoke particles, the electric field intensity, the distance between the plate electrodes, the electric field structure and the like. These soot particles, which would otherwise be uniformly distributed and escaped, are typically more intensively distributed near the anode plate at the point of escaping from the end of the electrostatic field after the action of the electric field. If the relatively concentrated oil smoke particles are intercepted and collected by a certain technical method, the more efficient purifying effect can be achieved. The electric field intensity matched with the prior art equipment on the market at present can completely meet the adsorption requirement, but the technical problems that the improvement is needed still exist:
1. the multi-stage high-voltage discharge is not adopted, the number and the density of discharge stages are not increased enough, and the smoke particles are not provided with stronger electricity attaching effect;
2. when coulomb force adsorption is carried out on most of the oil smoke particles which are ionized and electrified, the adsorption effect cannot be achieved to the greatest extent without designing enough dust collecting cathode plates and dust collecting anode plates;
3. the filter tank collection technology is not designed, escaped charged oil smoke particles cannot be effectively collected and intercepted, and the more efficient oil smoke purifying effect of the electrostatic field cannot be ensured.
