With the development of economy, everyone's life is on the right track. As the saying goes, food is the most important thing for the people. In China, the catering industry has become one of the industries with rapid development, great influence and wide coverage in recent years. Expenditure occupies an important position in the national economy and is an important link in the process of social reproduction. Since the beginning of the new century, the catering industry has played an important role in influencing the expenditure needs and promoting economic growth. Catering expenses are increasingly becoming a primary way of spending in people's daily life, which promotes the pace of economic development. As a result, the pollution of cooking fume discharged from the catering industry, which is rapidly developing in cities, is becoming increasingly serious, which has brought great damage to the environment and even human health.

The "oil smoke" emitted by our cooking is a large number of thermal oxidation differentiation products of edible oil and food at high temperature. When cooking, the oil is heated. When the temperature reaches the smoking point of edible oil at 171℃, it presents the blue smoke that differentiated in the early stage. As the temperature continues to rise, the differentiation speed is accelerated. When the temperature reaches 251℃, it presents a lot of oil smoke, accompanied by the smell of nose flushing, and the particle size of oil smoke is 1.11-1.3 microns. After analyzing the oil fume samples of fried food collected by the relevant departments from households, more than 221 chemical substances were detected, among which aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, esters, lactones and heterocyclic compounds were the main ones. Known mutation carcinogens such as volatile nitrosamines were also found in cooking oil fume. In other words, oil fume itself is a severe air pollution.

so how to avoid the pollution of oil fume? This has led to the emergence of "oil fume purifier", which is a kind of kitchen oil fume waste gas disposal equipment. It can effectively remove the oil fume from kitchen cooking and turn the oil fume into fresh air after disposal and purification, which is mainly used for the purification management of kitchen oil fume in hotels, restaurants, restaurants, campuses, institutions, factories and other places. Food frying, cooking and processing occupation; Oil spill heat treatment workshop, oil mist lubrication workshop, workpiece welding workshop and olefin boiler discharge and other industrial occasions.

when the oil fume is sucked into the electrostatic oil fume purifier by the fan, some large oil droplets and oil pollution particles are trapped on the flow equalizing plate due to mechanical collision and retention. When the airflow enters the high-voltage electrostatic field, under the effect of the high-voltage electric field, the oil fume gas is ionized and the oil mist is charged, and most of them can be degraded and carbonized; A few tiny oil particles move to the positive and negative plates of the electric field under the electric field force and airflow effect of the adsorption electric field, are collected on the polar plate, flow to the oil collection tray under the effect of their own gravity, and are discharged through the oil discharge channel, and the remaining micron-sized oil mist is degraded into carbon dioxide and water by the electric field, and finally clean air is discharged; Under the effect of the high-voltage generator, the air in the electric field produces ozone, which removes most of the odors in the flue gas to meet the national environmental protection requirements. Therefore, the "oil fume purifier" is a good choice for removing kitchen fumes! ?
