Awl line

　　The barbed wire of electrostatic precipitator is the main part of the cathode system of electrostatic precipitator. The utility model has the advantages of good volt ampere characteristic, strong adaptability to the change of dust specific resistance, and the cut-off voltage is more than 20000 volts higher than that of the dust collector using other corona wires.

　　The electric dedusting prick wire can be installed in various horizontal or vertical electrostatic precipitators. The electric field of the electric dedusting prick wire (cathode is also called discharge electrode or corona electrode) and the anode form a non-uniform electric field to generate corona current. It is composed of cathode line, cathode frame and cathode hanging device.

　　Characteristic

　　1. It is firm and reliable, with high mechanical strength, continuous wiring and no dropping. There are often thousands of cathode wires in one power supply area of ESP, and one broken wire will cause electric field short circuit.

　　2. Good electrical characteristics. The results show that the current density distribution on the anode plate is uniform and the average electric field strength is high. Low corona voltage, high breakdown voltage.

　　3. Easy to remove ash and low manufacturing cost.

　　Matters needing attention

　　It can be installed in a variety of horizontal or vertical electrostatic precipitators, with good volt ampere characteristics, strong adaptability to the change of dust specific resistance, cut-off voltage more than 20000 volts higher than other corona wire precipitators. The ability of corona discharge is related to the whole cusp (curvature) of corona discharge. When there is dust convergence at the cusp of corona discharge, its curvature is smaller, which has a great influence on its discharge effect.

　　There are many types of corona pole. The more the discharge sharp angle, the better the corona effect. However, the more the discharge sharp angle, the more difficult the fabrication and installation. Generally, the corona wire pole is connected with high voltage, and needs good insulation device. The interval between the corona wires should be appropriate. The interval too far affects the current of the corona, and the interval too close may cause screen defects between the corona wires, As a result, the electric field intensity on the corona wire surface is weakened. The upper and lower parts of the dust collecting pole of the dust collecting pole are fixed, and the dust collecting pole is grounded. Generally, it is required that the dust is easy to settle on the pole plate, and the secondary dust produced during the vibration is less. At the same time, it is required that the pole plate is light and rigid, and the dust is easy to sink and will not deform during the vibration.
