Abstract

The invention relates to the field of lampblack purification equipment, in particular to an electrostatic lampblack purifier. The purifier comprises a housing, and a front filtering and purifying device, a high-voltage ionization field, a low-voltage electrostatic adsorption field, an axial flow fan and a rear filtering and purifying device are sequentially arranged in the shell from left to right. The low-voltage electrostatic adsorption field comprises an electrode plate group and a driving box, a driving mechanism and a lifting mechanism are arranged on the driving box, an oil scraping mechanism used for scraping oil stains on the electrode plate group is arranged on electrostatic lampblack purifier utilizes an air flow as driving force to allow the lifting mechanism to drive the oil scraping mechanism to perform oil scraping operation on the electrode plate, so that real-time cleaning of the electrode plate is achieved, the service life of the electrode plate is prolonged, the electrode plate is kept in a stable and efficient oil mist particle adsorption effect all the time, the lampblack purification efficiency is improved, the electrode plate does not need to be disassembledand cleaned, time and labor are saved, and the maintenance cost of the lampblack purifier is greatly reduced.

Description

technical field [0001] The invention relates to the field of oil fume purification equipment, in particular to an electrostatic oil fume purifier. Background technique [0002] The cooking fume produced by the catering industry is mainly 0.01μm-100μm pollutant particles formed by the gasification and cracking of edible oil and food under high temperature. The existing electrostatic oil fume purifier adopts the principle of electrostatic purification. The exhaust gas containing oily fume is sucked into the ventilation duct under the action of the fan, and enters the pre-filter (purification and separation balance) device of the oil fume purifier. Oil mist particles are physically separated and evenly rectified. The separated large-particle oil droplets flow into the oil tank under the action of their own gravity and are discharged. The remaining small oil mist particles below 1 micron enter the high-voltage electrostatic field. The high-voltage electrostatic field adopts th...

Problems solved by technology

[0003] However, in the process of purifying the oil fume in the existing electrostatic oil fume purifier, due to the high viscosity of the oil particles, and the oil mist is easy to coke and carbonize, it is easy to stick to the low-pressure adsorption plate and cause damage to the plate. As a result, the oily layer of the plate is thicker, difficult to clean, the effect of oil fume removal gradually deteriorates, and the efficiency of oil fume purification is reduced. Therefore, it is necessary to disassemble and clean the plate in the low pressure area frequently, which is time-consuming and laborious, and the maintenance cost is high. In view of this, We propose an electrostatic lampblack purifier
