Description
[technical field]
The utility model relates to a kind of equipment and system thereof that is used to purify food and drink and food processing industry oil smoke noxious material and peculiar smell; particularly a kind of catering trade photochemistry oil smoke odor eliminator and device systems thereof of being used for belongs to atmosphere and urban and rural residents living environment resist technology field.
[background technology]
Reform and open up to the outside world town and country food and drink since 30 years, food-processing industry obtained tremendous development, living standards of the people are greatly improved, and produce a large amount of oil smoke and peculiar smell in the stir-fry process but cook, and peculiar smell is diffusion everywhere towards periphery, pungent unpleasant, severe contamination atmosphere and both urban and rural residents's living environment.
In general the catering trade flue gas is formed complicated component by kitchen range burnt gas and cooking fume two parts Combination pollutant.According to the study, have 200～300 kinds of chemical substances, 74 kinds of poisonous chemical compositions are wherein arranged.The kitchen range burnt gas is one group of Combination pollutant, and dust, soot, moisture and all cpds are arranged, and compound mainly contains aldehyde, ketone, hydrocarbon, alcohol, ester, aromatic compound etc.Wherein contain mutagen and carcinogenic substances such as benzo [a] pyrene (B[a] P), heterocyclic amine compound.
Cooking fume be edible oil or food under hot conditions, take place a series ofly to change the back and form.Will begin to occur low smoke when being heated to 170 ℃ as edible oil, along with the rising of temperature, the decomposition rate of oil is accelerated, and a large amount of cooking fumes can occur when reaching 250 ℃, and during people's cooking common oily temperature all about 250 ℃.Cooking fume also is one group of Combination pollutant, mainly from moving (planting) thing oil, fish, meat, vegetables and various condiment in the gastronomical process fry in shallow oil at high temperature, explode, thermal response when frying, as thermal oxidative reaction, heat polymerization, thermal oxide polymerisation, heat scission reaction and hydrolysis etc., generate some than some bigger materials of normal plants oil molecule (triglyceride) polarity, as oxidation products, thermal polymerization product, thermal oxide polymerizate, the hydrolysate (free-fat etc.) of triglyceride class.What is more, and the oil temperature is fried in big fire soon can produce carcinogenic substances such as volatile nitrosamine and Ppolynuclear aromatic in time more than 270 ℃, and typical poisonous carcinogenic substance is exactly nitro polycyclic aromatic hydrocarbons (PAH) DNP.
In the blast pipe in restaurant, a large amount of greases, dust, soot and moisture are arranged in the effluent, these materials can and remove in the wet goods operation and remove in smoke abatement and dust control, but also contain multiple noxious material in the waste gas of discharging and peculiar smell is difficult for removing, and endanger very big.In addition, also contain venomous injurants such as bacterium, virus in the exhaust in restaurant.Caused negative effect not only for peripheral resident living environment, working environment, and the grievous injury people's is healthy, contains multiple poisonous chemical composition in the cooking fume, human body is had lungs toxicity, immunotoxicity, genetoxic and potential carcinogenicity.Hong Kong Department of Health proposes the toxicity evidence: confirm certain toxic material DNP in the food and drink oil smoke, oil smoke causes lung cancer, and DNP is No.1 killer, and meal kitchen personnel boil a meal, and sucking the DNP total amount is outdoor 188 times! The people who lives in for a long time in such environment easily suffers from lung cancer and other disease.Poisonous, smell pollution thing in the oil smoke and venomous injurants such as bacterium, virus are also suddenly treated efficiently to purify and remove.The scholar advises that compatriots do improvement more as far as possible on mist extractor equipment!
In the past, people attempt to make method treatment and purification peculiar smell such as water flushing and activated carbon filtration, absorption, have not also caused secondary pollution but effect is not only good.The somebody adopts the method for the biological biological fluids that eliminates the unusual smell, with taste removal working solution atomizing, be sprayed near the space kitchen, allow smell substance molecule in the taste removal working solution droplet absorption oil smoke, the smell substance molecule and the taste removal working solution that are adsorbed react, the also very high secondary pollution in addition of poor effect that the result not only eliminates the unusual smell but also cost.
