Static fume purification device and extractor hood applying device

Abstract

The invention relates to a static fume purification device, which comprises a dust collecting electrode and an ionization electrode. The dust collecting electrode comprises at least two dust collecting plates arranged at an interval; the ionization electrode is arranged under the dust collecting electrode; each dust collecting plate forms a folded plate at least provided with one bending part; theionization electrode is provided with a main body part forming a flat plate; and multiple spikes arranged facing the dust collecting electrode are arranged on the main body part. According to the static fume purification device provided by the invention, each dust collecting plate forms the folded plate at least provided with one bending part, so that not only is a contact area of the dust collecting electrode and fume increased, but also an impact effect on fume particles can be also improved at a connected part of each bending part and the corresponding dust collecting plate, the fume velocity is reduced, the time when fume passes through the dust collecting plate is prolonged, a physical filtering effect on fume gases is improved, and adsorption and removal effects of the fume purification particles are further improved. The ionization electrode provided by the invention is provided with the multiple spikes facing the dust collecting electrode, and an ionization effect is improvedthrough the spikes, so that a fume purification effect is improved.

Description

technical field [0001] The invention relates to an electrostatic oil fume purification device and a range hood applied with the device. Background technique [0002] 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 purification devices, water mist spray Shower type oil fume purification device and electrostatic oil fume purification device. [0003] Among them, the working principle of the electrostatic oil fume purification device is: use a high-voltage electrostatic field to ionize the gas passing through the electrodes, and then adsorb it on the electrodes to achieve the purpose of purifying the oil fume. Commonly used electrostatic devices are divided into two types: the modular design of ...

Problems solved by technology

[0004] In the above-mentioned existing electrostatic oil fume purification devices, dust collection plates and ionization pole wires with ordinary flat structure are generally used. The dust collection plate with ordinary flat structure is weak in physical filtration of oil fume gas, and the ionization strength of ionization pole wires is also low. Generally, for large concentrations of oil fume, the purification effect is poor
