Low-altitude electrostatic oil fume purifier and purification method thereof

Abstract

A low-altitude electrostatic oil fume purifier of the present invention comprises a wet-type electrostatic purification system and an adsorption purification mechanism connected with the wet-type electrostatic purification system. The wet-type electrostatic purification system comprises a shell, a control electric box and a fire extinguishing system which are installed at the two sides of the shell respectively, a direct-current high-voltage power source is arranged in the control electric box, and a cylindrical honeycomb electric field electrically connected with the direct-current high-voltage power supply is arranged in the shell. The adsorption purification mechanism comprises an exhaust fume collecting hood and a plurality of filter units connected with the exhaust fume collecting hood, a plurality of oil fume extraction motors are arranged in the exhaust fume collecting hood, the bottoms of the oil fume extraction motors are connected with filter pipelines, and each filter unit comprises a water tank containing oil absorption alkali liquor, a filter material layer and a vertical filter material net which are arranged in the water tank. One end, far away from the oil smoke exhaust motor, of each filter pipeline penetrates through the filter material layer and extends into the oil absorption alkali liquor of the water tank box, the vertical filter material net is fixed on the inner wall of the water tank box above the filter material layer, and an exhaust port connected with the vertical filter material net is formed at the edge, close to the opening, of the water tank box.

Description

technical field [0001] The invention relates to the technical field of oil fume treatment, in particular to a low-altitude electrostatic oil fume purifier and a purification method thereof. Background technique [0002] With the rapid development of my country's economy, the continuous advancement of industrialization and urbanization, the continuous improvement of people's living and consumption levels, and the rapid development of industry and catering industries, oil fume pollution has become the focus of people's attention. Oil fume is usually formed by vaporization and volatilization of aliphatic hydrocarbon compounds with low boiling points during heating. The oil fume pollution in my country mainly comes from the catering industry, textile industry, food processing industry, metal processing industry and other fields. On the one hand, oil fume pollution will affect people. work and living environment, and even affect the health of people and animals. On the other hand,...

Problems solved by technology

[0003] In order to reduce the oil fume pollution in the kitchen, most of the traditional methods are to install range hoods in the kitchen. At present, there are many problems in domestic range hood equipment, mainly reflected in the fact that the equipment has little effect on the removal of oil fume pollutants. It can effectively deal with oil fume pollution, and the structural design of the equipment is relatively complicated. Its main technology is to use the principle of exhaustion

However, this purification method of the range hood purifies the house but pollutes everyone. It does not completely purify but is discharged outdoors to pollute the atmosphere, especially in large public canteens with concentrated population such as factories and universities. serious
