Many restaurants and restaurants in China's catering industry emit fumes without organization. Oil fume contains many harmful substances, which are discharged outdoors without any treatment. It not only pollutes the living environment of the surrounding residents, but also releases a large number of hydrocarbons into the atmosphere. It is very easy to mix with other dust to form inhalable particulate matter, which will damage the air quality. The problem of cooking fume pollution disturbing people has become one of the hotspots of environmental complaints of urban residents, and the control of air pollution has become the common aspiration of the general public. Shenzhen Xili Environmental Protection Technology Co., Ltd. develops and produces a new kind of kitchen fume purifier, which is especially suitable for the Units discharging fumes such as catering industry, canteen, hotel, barbecue shop, food processing factory, etc. After testing by authoritative departments and using by users, all indicators have reached the standard.
1. Oil fume hazard
Food processing in restaurant kitchens, including frying, frying, boiling, frying and other processes, will emit a large number of high-concentration grease, organic matter and heating decomposition or cracking of a large number of high-concentration soot, which will be released over the city for a long time, directly threatening the health of urban residents. As most hotels and restaurants are located in downtown areas or residential areas, their fume emissions have a serious impact on the surrounding residents and the environment. The cooking fume in catering industry contains pyrolytic substances such as benzene, aldehyde, alkane, ketone, alcohols, olefins and some cooking fume vapors. These harmful substances seriously affect human settlements and endanger human health. Among them, soot condensates at high temperature have strong carcinogenic and mutagenic effects.
2. Working Principle and Characteristics of Kitchen Fume Purifier
The kitchen lampblack purifier uses high voltage electrostatic principle and multi-electric field module combination technology to charge, absorb and oxidize the lampblack, hot crack corner dust and fuel dust produced in cooking under the action of static electricity and wind, so as to realize the effect of purifying lampblack and smoke dust and removing odor. At the same time, the ozone generated in the electric field can also sterilize, remove odor, remove harmful gases, and discharge clean air through the outlet, so as to achieve emission standards.
3. Characteristics of Kitchen Fume Purifier
1. Unique design structure
Dongrun oil fume purifier adopts two-zone high voltage electrostatic precipitator and electrostatic reinforced fiber dust collector. Its design structure is unique and novel, and its effect is good. Moreover, the corona wire structure is advanced, occupies a small area and is easy to install.
2. Can eliminate diesel fuel pollution
It has the function of purifying diesel stove and eliminating diesel pollution. The general kitchen fume purifier only eliminates cooking fume, but has no way to deal with diesel fume. This kind of kitchen fume purifier has a good effect in eliminating cooking and diesel fume.
3. Easy cleaning and stable operation
Because of the modular design and split drawer design, it can not only meet the requirements of different purification rates, but also be easy to install and clean. The bottleneck problem that restricts the wide application of kitchen lampblack purifier is the maintenance and cleaning of lampblack purifier. To solve this problem, long-term application, stable operation and lasting effect can be achieved.
4. Low resistance and low operating cost
Most of the environmental protection facilities can not be widely used for a long time, and are accepted by users and willing to use it. A very important problem is that the operation cost is small, the operation cost is small, this environmental protection facility will have a strong vitality;
5. Using corrosion-resistant materials and arc-drawing conditions, the equipment has a long service life.
The design overcomes the shortcomings of surface discharge and arc-drawing of traditional electrostatic lampblack purifier, so as to prolong the service life of the equipment.
IV. Application of Kitchen Fume Purifier
It is mainly used for barbecue, stir-frying, cooking, eliminating the hazards caused by cooking fume, and solving the problem of strong fume pollution reflected by the residents; using this kitchen fume purifier to eliminate fume pollution in barbecue shops; using this kitchen fume purifier to solve the odor pollution in plastic factories in cities throughout the country.
Compared with the high-altitude fume purifier, the kitchen fume purifier has many good performances and wide applicability. Compared with the high-altitude fume purifier used before, it can be seen that the wet purification efficiency is very low, the water solution used to remove the fume is not easy to be treated, and it is easy to cause secondary pollution, and the high-altitude fume purifier occupies a small area. Although several canteens have installed this kind of high-altitude lampblack purifier, there is no use of high-altitude lampblack purifier now.
Although the high-altitude oil fume purifier has less investment cost and occupies less area, its purification efficiency is low, especially it is not convenient for daily replacement and maintenance, and its filtrate has become a source of pollution that is difficult to dispose of. Although the investment of electrostatic fume purifier is slightly larger, it has small volume, high purification efficiency, convenient maintenance, stable operation, and no secondary pollution. It has become one of the mainstream of fume purifier market, and is comparable to kitchen fume purifier. Now most major cities in the country use this kind of fume purifier.
Kitchen lampblack purifier is a new field of environmental protection industry. It requires that the efficiency of cooking lampblack purifier can not only meet the requirements. Fuel carbon particles produced by diesel fuel should also be eliminated; this kitchen lampblack purifier not only can be used, but also has small size; it is not only convenient to operate, but also can not produce secondary pollution. The electrostatic lampblack purifier and kitchen lampblack purifier have obvious advantages over the high-altitude lampblack purifier, while the technology and performance of this kind of kitchen lampblack purifier produced by environmental protection research and development of Huanjiou in Dongguan have more advantages and application prospects.
