A high-voltage electrostatic oil fume removal device

Abstract

The invention discloses a high-voltage static cooking fume removing device. The high-voltage static cooking fume removing device comprises an insulation shell, an ionization module and a dust collection module, wherein the ionization module and the dust collection module are arranged in the shell and comprise high-voltage polar plates and grounding polar plates, and the high-voltage polar plates and the grounding polar plates are arranged in a crossed manner. The high-voltage static cooking fume removing device is characterized in that the ends of the high-voltage polar plates are bent to form first flanges, and the ends of the grounding polar plates are bent to form second flanges; the high-voltage static cooking fume removing device further comprises a plurality of pressing buckle structures connected with the first flanges and the second flanges at all ends; the pressing buckle structures comprise installation frames and pressing strips, wherein arched insertion strips are arranged on the surfaces, facing the first flanges or the second flanges, of the installation frames, gaps allowing the first flanges or the second flanges to be inserted into are formed between the insertion strips and the surfaces, and insertion holes are formed in the positions, adjacent to the insertion strips, on the installation frames; and pressing connecting pieces are arranged at the positions, corresponding to the insertion holes, on the pressing strips, penetrate the insertion holes and then abut against the back sides of the ends of the high-voltage polar plates or low-voltage polar plates.

Description

technical field [0001] The invention relates to an oil fume removal device, in particular to a high-voltage electrostatic oil fume removal device used for range hoods. 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: mec...

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 avoid the phenomenon of sparking and arcing caused by virtual contact with the high-voltage electrode. And can not discharge oil in time, therefore, also need further improvement
