With the progress and development of science and technology, major scientific research companies have also made good achievements in the innovation of oil fume purifier. Nowadays, the brand and shape of lampblack purifier are very wide on the market, but the general purification principle is very few.
1. Electrostatic type
Electrostatic soot purifier traps soot particles by using negative ions produced by electrons and electrons colliding with air molecules released by cathode in high voltage electric field, which makes soot particles charged. Using the electric field, the charged soot particles are adsorbed on the anode to remove the soot.
According to the different shapes of the electric field plate in the electrostatic oil fume purification equipment, it can be divided into honeycomb plate and linear plate.
The lampblack molecule is purified by irradiating lampblack molecule with special wavelength ultraviolet light.
Photolysis and oxidation of oil fume purification technology is the use of ultraviolet-C band light to change the oil molecular chain. At the same time, this ultraviolet radiation reacts with oxygen in the air to produce ozone. Ozone molecule oil burns to produce water and ozone, while the odor of the flue gas is eliminated.
Wet type mainly uses water spraying (water curtain) to filter oil mist in flue gas, which is called wet type. The method has high removal rate of large oil mist particles and low removal rate of small particles. Because of the hydrophobicity of oil smoke droplets, various surfactants and emulsifiers need to be added to the washing water of the device to improve the mixing performance of oil and water. It can remove some harmful gases and odors dissolved in water, and realize the treatment of fire smoke and lampblack at the same time.
At present, the wet oil fume purifier is the best product besides oil fume. The integrated lampblack purifying machine adopts the principle of liquid foam cleaning, and can automatically clean low altitude straight row lampblack in the machine body. No complex pipeline facilities, simple installation.
