Information
Kitchen flue gas mainly refers to the hot oil flue gas produced by kitchen operations. These flue gases are more harmful to human bodies than cigarettes to people.

The fume pollution is shocking. The fume emitted every day has become an important source of air pollution that cannot be ignored. The oil fumes generated in the kitchen will not only pollute the kitchen space, but also may have an adverse effect on the indoor environment of the adjacent area space. At present, the environmental protection bureaus of major small and medium-sized cities have received numerous complaints about hotel kitchen smoke emission affecting residents ’daily lives; people ’s complaints are also endless.

Production of kitchen fumes:

Kitchen smoke is mainly composed of cooking oil smoke and fuel combustion products.

Cooking oil fumes are formed after a series of changes in cooking oil or food under high temperature conditions. Studies have shown that cooking oil fume is a group of mixed pollutants, the composition is extremely complex, there are as many as 200 to 300 species, including volatile nitrosamines and other known mutagen and carcinogens. At an oil temperature of 270 degrees, trace amounts of mutagenic crotonaldehyde and acetone concentrated gas can be detected from the oil fume of vegetable oil and soybean oil. At the same time, during the cooking process, the water in the food vaporizes and expands rapidly, partially condenses into mist, and then forms visible oil fumes with the oil fumes. It can be seen that cooking fume is an aerosol vapor of volatiles and condensate of edible oil and food at high temperature, and is a group of mixed pollutants. In addition, cooking oil fume often carries some pungent odor. From the morphological point of view, cooking fume includes inhalable particles PM10 and PM2.5, and gaseous pollutants.

In addition, barbecue shops with mutton skewers, barbecues, and grilled chicken wings as the main business have gradually appeared in cities. They use coke and charcoal as fuel to produce a large amount of dusty smoke. The oil fumes in this fume gas are mainly carcinogens such as polycyclic aromatic hydrocarbons, nitroaromatic hydrocarbons, and heterocyclic amines, as well as tar, CO, and CO2. The dust particles in the fume gas are mainly the ash particles (ie fly ash) carried out by the gas and a part of the unburned ember carbon particles. The particles with a particle diameter of less than 10 μm are called flying dust, and the particle diameter is 10 to 100 μm Falling on the ground soon is called falling dust. Although the fixed carbon content of charcoal is relatively high, black smoke still occurs during the charcoal burning process, mainly due to incomplete combustion of fuel. According to fuel combustion theory and fuel composition analysis, it is impossible to make the incomplete combustion loss equal to zero in the actual combustion process. Even if the combustible matter is 100% burnt, the non-combustible matter (such as ash, non-combustible sulfur, etc.) still exists, so the smoke emitted is white.

Exhaust gas produced by the fuel combustion products in the living room is different due to the difference in fuel and the degree of complete combustion. The main components of fuel combustion products are CO, NOX, SO2 and soot, which will cause pollution to the environment. According to statistics, coal combustion products total up to hundreds of compounds, which can be divided into the following seven categories: carbon oxides, oxygenated hydrocarbons, polycyclic aromatic hydrocarbons, sulfur oxides, fluorides, metals and non-metal compounds And suspended particulate matter. Natural gas and liquefied petroleum gas are clean fuels, and are easy to burn completely, with less particulate matter and lighter pollution, but they can still release a small amount of CO, CO2, NOX, SO2 and other pollutants, polluting the indoor environment. Studies have shown that the average value and range of combustion pollutants produced by kitchens using different fuels are different

The harm of oil fume to human body:

For women: Oil fume contains carcinogen benzopyrene. Long-term inhalation of oil fume. One is the pathological changes of human tissues. The proportion of women aged 40-60 years who are exposed to oil fume for a long time will increase several times. Rough skin has wrinkles, hair loss, stains, and fat oil particles blocking the pores of the skin, causing women's skin to be rough and dry, wrinkles, and stains, making people more fattening. Oil fumes can damage the body's immune system, and have 5 years of cooking experience. There will be varying degrees of hair loss.

Children: huge harm to children. Inhalation of oil fumes can cause eye, nose, and respiratory tract lesions and affect normal growth and development. Children and children are in the stage of long body growth. The pollution of oil fumes is prone to conjunctivitis and rhinitis. , Pharyngitis, tracheitis, pneumonia and other diseases, seriously endangering the healthy growth of children.


For the elderly: It is more likely to cause geriatric diseases, and the fat oxides in oil fume will cause cardiovascular and cerebrovascular diseases, especially the fumigation of oil fume for the elderly for many years, which is more susceptible to disease.

For the family: Oil fumes invade the respiratory tract, which can cause symptoms such as loss of appetite, upset, lack of energy, fatigue and weakness; medically known as "oil fume syndrome". The symptom group is loss of appetite, although there is a sense of hunger, but the taste is tasteless, bored in the heart, poor in spirit, drowsiness, and general weakness. Usually diet is very little, but the weight gradually increases, becoming obese who have a big belly! The main component of oil fume, acrolein, has a strong irritation to the mucous membranes of the eyes, nose, and throat, which can cause chronic keratitis, rhinitis, pharyngitis, tracheitis, pneumonia, and other diseases. In addition, there are 74 chemicals in the oil fume that can change the cells. Causes male infertility to become a "family killer".
