Static lampblack purifying device and extractor hood with same

Abstract

The invention relates to a static lampblack purifying device which comprises a dust collecting pole and an ionization pole. The dust collecting pole comprises at least two spaced dust collecting plates, and a bent plate with at least one bent portion is formed by the dust collecting plates. The ionization pole is provided with a main part forming a slab, a plurality of openings are formed in the main part at intervals, and therefore the main part forms a net-shaped structure. Sharp spines arranged towards the dust collecting pole are arranged at the joints of the net-shaped structure. According to the static lampblack purifying device, the bent plate with the at least one bent portion is formed by the dust collecting plates, so that the contact area of the dust collecting pole and lampblack is increased, the colliding function on lampblack particles is improved, and the lampblack flowing speed is reduced. Therefore, the time of the lampblack passing through the dust collecting plates is prolonged, the physical filtering function on lampblack gas is enhanced, and then the adsorbing and removing effect of lampblack purifying particles is improved. The sharp spines arranged towards the dust collecting pole are arranged at the joints of the net-shaped structure of the ionization pole, the ionization effect is improved through the sharp spines, and therefore the lampblack purifyingeffect 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 ...

AI Technical Summary

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
