Description

Arc-shaped channel capturing device

Technical Field

The invention relates to an arc-shaped channel capturing device.

Background

Gas purification apparatuses have been widely used in industrial production, public facilities, homes, and the like, for purifying air or other gases. In particular, high-voltage electrostatic purification devices have been widely used. Such high voltage electrostatic cleaning devices typically employ two high voltage electrode plates to clean the gas, such as air, passing between the electrode plates and to adsorb the particles carried therein. The electrode plates are usually made of conductive materials such as metal, which may cause an electric shock event, and even when the power is turned off, the charges stored in the electrode plates may cause an electric shock, so that an additional protection device needs to be added to the purification apparatus. In addition, electrical breakdown and leakage between the electrode plates can cause a reduction in the operating efficiency of the purification apparatus and can also produce harmful ozone. The protection method generally employs an insulating material to completely wrap the conductive portion to prevent electric leakage. The electrode plates coated with the insulating materials are spliced together, and the placing angle between the electrode plates is parallel to the direction of the air duct, so that the wind resistance is small, but the problem is that the catching time is short under the condition of unchanged wind speed. Because the capture time is short: 1. the influence is that the depth (the length in the air duct direction) of the electrode plate is deepened; 2. meanwhile, the distance between the two electrodes is shortened, and the deflection distance (the movement distance vertical to the air channel direction) required by the capturing action is reduced; 3. the electrode spacing is reduced, so that potential safety hazards are increased; 4. under the condition that the same wind reaches the sectional area, more electrode plates are needed, the wind resistance is increased, the cost is increased, the potential safety hazard is increased due to the reduction of the electrode distance, no matter the depth is increased, and the electrode plate arrangement density is encrypted, which is contrary to the requirement of smaller volume and higher energy efficiency in the market at present.
