Description
Technical Field
The present invention relates to an electrostatic cleaning unit.
Background
The oil separation degree of the range hood on the market at present can reach 90% or more, but part of oil smoke and a large amount of PM2.5 particles are discharged outdoors. As the outdoor air quality is increasingly worried, the outdoor activities and the physical health of human beings are seriously affected, and the lampblack is taken as one of main pollution sources of the outdoor air, so that the purification of the exhaust body outside the lampblack absorber is particularly important. In order to reduce the pollution of the oil smoke to indoor and outdoor environments and reduce the rejection of the public, especially the public around the area to catering enterprises, the oil smoke purifying device is needed to be adopted, and the common oil smoke purifying device in the prior art comprises: mechanical oil smoke purifier, water mist spray type oil smoke purifier and electrostatic oil smoke purifier. The electrostatic technology is applied to the range hood, so that a good fume purifying effect can be achieved.
The existing high-voltage electrostatic oil fume purifying device generally has two structures, namely a honeycomb type electric field generator and a flat plate type electric field generator. The cathode of the former is a hexagonal hole of regular hexagons integrally connected with each other, the shape is like a honeycomb, a long needle is arranged at the geometric center of each regular hexahedral hole, and the long needle is an anode. The positive electrode of the output end of the high-voltage power supply is connected with the anode of the electric field generator, and the negative electrode of the power supply is connected with the cathode of the electric field generator. Corona is generated near the needle point after the power is on, air is ionized, a large amount of charged positive ions and negative ions are generated, and an adsorption electric field is arranged at the rear part of the needle point. When the oil smoke particles enter the honeycomb electric field generator, the oil smoke particles are captured by positive and negative ions to become load oil smoke particles. Under the drive of wind force, the load particles are acted by the electric field force at the adsorption field and move towards the corresponding collector, so that the purposes of soot deposition and air purification are achieved. In the same regular hexahedral hole, the working voltage of the front end ionization field is greatly different from that of the rear adsorption field. It has the following disadvantages: the voltage is too high, and the spark discharge is performed on the rear electric field; the working voltage is reduced to meet the rear requirement, the corona at the front end is weak, a large amount of positive and negative ions cannot be generated, the fume purifying capability is reduced, and the production process is complex.
An efficient electrostatic fume removal electrode assembly for fume and exhaust gas as disclosed in chinese patent CN203972134U is also a typical high voltage electrostatic cleaning device of honeycomb structure. Although the electrostatic dust or oil smoke particles have good charging capability, the structure has huge whole volume and is very troublesome to install and detach.
