Technical Field

The utility model relates to an oil smoke clarification plant, concretely relates to oil smoke clarifier electrostatic insulation structure.

Background

There are many kinds of oil fume purifying apparatus, and the oil fume purifying treatment technology in the market at present has mechanical separation method, catalyst burning method and electrostatic treatment method.

The electrostatic treatment method is that under the action of an external high voltage, electrons released from the surface of a metal wire of a negative electrode or the vicinity of the metal wire of the negative electrode rapidly move to a positive electrode, collide with gas molecules and are ionized. When oil smoke waste gas passes through the high-voltage electric field, oil smoke particles collide to capture gas ions in a very short time to cause charge, and the oil smoke particles move to the positive dust collecting plate under the action of electric field force, so that the separation effect is achieved. Because the dust with smaller particle size is easy to capture, the purification efficiency is high and can reach 85-95%. Its purification mechanism differs from the gas method in that: the separating force is electrostatic force and acts on the particles directly instead of acting on the airflow, so that the separating device has the characteristics of low energy consumption and small resistance.

Electrostatic dust collection utilizes a high-voltage electric field to adsorb dust, and the high-voltage electric field is a main factor influencing dust collection efficiency. Under the moist operating mode, if electrostatic precipitator adopts traditional insulator bottle structure, there are a series of problems such as the insulator bottle inner wall is easy deposition, dewfall, bursts easily, also has certain danger when changing and maintaining insulator bottle simultaneously. Therefore, the problem of electric field insulation becomes a bottleneck restricting a high-voltage electric field, and the electric field insulation is often broken down to cause environmental pollution accidents such as electric field grounding and failure of electrostatic dust removal equipment.

Negative plate screw rod and positive plate screw rod are fixed on insulating frame, and the frame of this device is insulating, but when in actual use, general frame is mainly made with the metal sheet, and non-insulating just so need settle the insulator structure at the fixed position between negative plate screw rod and positive plate screw rod and frame, and during the oil smoke purifies, the easy accumulation oil smoke of insulator structure at the inside position of frame leads to the static gathering to burn out easily and damage the insulator.
