A high-voltage electrostatic oil fume purification device

Abstract

The invention discloses a high voltage electrostatic oil fume purification device. The high voltage electrostatic oil fume purification device comprises a shell and an electrostatic device arranged in the shell, wherein the electrostatic device comprises an ionization module and a dust collection module; each of the ionization module and the dust collection module comprises a mounting skeleton, high-voltage polar plates, zero polar plates and an energization sheet; the high voltage electrostatic oil fume purification device is characterized in that inserting grooves arranged at intervals are formed in the left side and the right side of the top of each mounting skeleton; the end parts of the high-voltage polar plates and the zero polar plates penetrate through the inserting grooves to be in contact with the energization sheets; limiting grooves extending in the longitudinal direction are formed in the left inner side wall and the right inner side wall of each mounting skeleton; the width of the limiting grooves is consistent with the thickness of the high-voltage polar plates and the zero polar plates; and the parts, corresponding to the limiting grooves, of the two ends of the high-voltage polar plates and the zero polar plates are tightly clamped into the limiting grooves. Since the limiting grooves are formed in the skeletons of the electrostatic device, the polar plates can be effectively clamped tightly, in addition, the consistency of interval differences among the polar plates is guaranteed, and the mounting strength is also enhanced, therefore, the mounting is more reliable.

Description

technical field [0001] The invention relates to a purification device, in particular to a high-voltage electrostatic oil fume purification device. Background technique [0002] At present, the better range hoods on the market can achieve 90% or more in terms of oil separation, but in fact, some oil fumes and a large number of PM2.5 particles are directly discharged outdoors. As the quality of outdoor air is increasingly worrying, seriously affecting human outdoor activities and physical health, oil fume is one of the main pollution sources of outdoor air, and it is particularly important to purify the exhaust gas from the range hood. [0003] In order to reduce the pollution of oil fume to the indoor and outdoor environment and reduce the rejection of catering enterprises by the public, especially the public around the area, it is necessary to use oil fume purification devices. The oil fume purification devices commonly used in the prior art include: mechanical oil fume puri...

Problems solved by technology

For example, the Chinese patent application number 201420717912.6 discloses a range hood and its high-voltage electrostatic oil fume separator, including an insulating shell, a plate-type high-voltage ionization device, and a plate-type high-voltage electrostatic adsorption device. The high-voltage electrostatic adsorption device includes a plurality of alternately separated Cathode sheet and anode sheet, each cathode sheet is threaded together by bolts and separated by a metal spacer, each anode sheet is threaded together by bolts and separated by a metal spacer, this type of device is troublesome to install and disassemble, and four Up to six poles run through it, which makes the smoke exhaust resistance of the range hood very large, and also increases the working noise. At the same time, the way of insulating material wrapping is difficult to guarantee the insulation safety in a humid and greasy environment.

[0004] There are also some electrostatic devices that are easy to disassemble, such as a range hood disclosed in Chinese patent application No. 201210414483.0, and a wide plate electrostatic precipitator module disclosed in Chinese patent application No. 201010223710.2. However, this device still has certain deficiencies in the strength of the overall structure and the stability of the installation, and it cannot effectively control the virtual contact of the electrodes and the difference in the distance between the plates, so it is difficult to avoid the The ignition and arcing phenomenon caused by the virtual contact of the high-voltage electrode, and there is no specific power supply method; in addition, the above-mentioned existing electrostatic purification device, the power supply of the high-voltage plate and the zero plate is usually realized on the same side, and the high-voltage The polar plate and the zero plate are connected due to oil pollution in the special scene of the range hood, which makes the purification function invalid
