Description
Technical field
The present invention relates to the pollutant control in green technology and energy-saving and emission-reduction, particularly a kind of cooking fume treating apparatus.
Background technology
Cooking fume refers to grease, organic matter and the heat resolve thereof or pyrolysis product that volatilize in food cooking process, wherein pollutant can be roughly divided into three classes: solid granulates, miniature droplets and gaseous state volatile organic pollution (Volatile Organic Compounds, VOC).The oil smoke of catering industry discharge capacity of China, pollutant emission kind and the conditional relationship such as the style of cooking, scale are close, and pollutant kind comprises alkane, alkene, aromatic hydrocarbon and oxygenatedchemicals etc.Along with the development of society and the rapid progress of service trade, oil smoke of catering industry has become the very important pollution sources of urban atmosphere.China's refined edible vegetable oil output 3878.54 × 10 in 2010
4t, wherein town dweller on average buys edible vegetable oil 8.84kg for each person every year, and rural area is 6.31kg, then resident consumes vegetable oil 1015.57 × 10 every year
4t.Cooking fume VOCs emission factor is 5.03g/kg, then being often only family cooking can produce VOCs5.1 × 10
4t.
China puts into effect " cooking fume discharge standard (trying) " (GB18483-2001) as far back as calendar year 2001, specifies the highest permission concentration of emission of catering trade unit oil smoke and the minimum clearance of cooking fume control equipment.But " try " and still put into effect without more careful standard for many years, also describe the complexity of such pollution source apportionment and the immature of Treatment process to a certain extent, a kind of mature technology of cooking fume pollutant control of the application that suits large area to popularize is badly in need of in society.
Existing oil smoke processing technology has the kinds of processes such as inertial separation method, common filtration method, active carbon adsorption, liquid scrubbing method, electrostatic deposition, all has respective limitation.As in inertial separation method and filtration method, because particle viscosity in oil smoke is large, clean and maintenance work is quite difficult; Active carbon adsorption constantly changes filtrate, and operating cost is higher; Liquid scrubbing method and electrostatic precipitation rule easily produce the secondary pollution such as waste water and ozone respectively, fail thorough contaminated solution problem.In addition, above-mentioned technology all only pays attention to the removal of particle, and less to the VOC material effect in flue gas, and pollutant removal is not thorough.Therefore, analyze from the physicochemical properties of oil smoke composition, develop a kind of fume purifying method, gas-liquid-solid three-state polluter is removed on low-energy-consumption high-efficiency ground, does not produce secondary pollution simultaneously, has extremely important realistic meaning.
Because the polluter in cooking fume mainly comprises miniature liquid-solid particle and VOC material, VOC be defined as fusing point lower than room temperature the VOC of boiling point between 50-260 DEG C, therefore, special heat pump is adopted the temperature in waste gas to be detached, waste gas being reduced to uniform temperature makes VOC material condensation become liquid, in conjunction with certain physical cleaning mode, integrate out a set for the treatment of system, complete the advanced treating to cooking fume, provide temperature to be used for output hot water for user simultaneously.This be a kind of novel, efficient while eco-friendly oil smoke clean technologies, produce hot water simultaneously.
