Embodiment 1

[0063] Infrared spectrophotometry to measure the concentration of oil fume: use an infrared spectrophotometer to determine the content of oil fume dissolved in carbon tetrachloride solvent, the content of oil fume is determined by the wave number of 2930cm 1 (CH 2 stretching vibration of the CH bond in the group), 2960cm 1 (CH 3 stretching vibration of the CH bond in the group) and 3030cm 1 (Stretching vibrations of C-H bonds in aromatic rings) Absorbance A at the band 2930 , A 2960 and A 3030 Calculation.

Embodiment 2

[0064] Embodiment 2: the standard curve of soot concentration to absorbance, its steps are as follows:

[0065] (1) Add 300ml of edible oil to a 500ml three-necked bottle, insert a thermometer with a range of 500°C, when the temperature of the edible oil is 120°C, open the heating for 30 minutes, and then install an air condenser directly above the three-necked bottle to heat up. To 300 ℃, reflux for 2h, and prepare standard oil samples in a three-necked flask.

[0066] (2) On a balance with an accuracy of 1 / 100,000, accurately weigh 1 g of the refluxed standard oil sample into a 50 ml volumetric flask, and use the analytically pure CCl after re-distilling (controlling the temperature at 70-74 °C). 4 Dilute to the mark to obtain high-concentration standard solution A. Take 1.00ml of solution A in a 50ml volumetric flask and dilute to the mark with the above CC14 to obtain standard intermediate solution B. Pipette 0.25ml, 0.5ml, 1.0ml, 1.5ml, 2.0ml, 2.5ml, 3.0ml, 3.5ml of sol...

Embodiment 3

[0070] The formula of oil fume removal efficiency: P=(C 前 -C 后 ) / C 前 ×100%.

[0071] of which: C 前 The concentration of soot before catalysis; C 后 The concentration of soot after catalysis; the catalytic efficiency of P soot.

[0072] like Image 6 Shown: 601 is an air compressor, 602 is a buffer bottle, 603 is a drying tower, 604 is a flow meter, 605 is a soot generating device, 606 is a thermometer, 607 is a pressure regulator, 608 is a reactor, 609 is a thermometer, 610 is a heating furnace, 611 is a controller, 612 is an absorption pipe, 613 is an ice-water mixture, 614 is a rotameter, a is an oil fume pipeline, b is a sampling pipeline, and c and d are gas exhaust pipelines; device 601 , 602, 603 are used to provide high-speed, stable, dry air, which is equivalent to the fan of a range hood; devices 604 and 614 are used to measure the flow rate of the air; devices 606 and 609 are used to measure the temperature in the reaction device; devices 605 and 607 Used to he...

Abstract

The invention belongs to the field of oil smoke purifying technology for catering trade, in particular to an oil smoke purifier suitable for updraft smoke exhausters. The oil smoke purifier comprises The invention belongs to the field of oil smoke purifying technology for catering trade, in particular to an oil smoke purifier suitable for updraft smoke exhausters. The oil smoke purifier comprisesa gas into water vapor and carbon dioxide gas to achieve the function of treating both the incidental and fundamental aspects. Thus the oil smoke purifier is more environmentally friendly and causes ne gas into water vapor and carbon dioxide gas to achieve the function of treating both the incidental and fundamental aspects. Thus the oil smoke purifier is more environmentally friendly and causes no pollution.o pollution. case, a catalytic unit and a heating unit, wherein the catalytic unit is arranged in the case, and the heating unit is installed on the case. The catalytic unit comprises a front metallic pipe bindia case, a catalytic unit and a heating unit, wherein the catalytic unit is arranged in the case, and the heating unit is installed on the case. The catalytic unit comprises a front metallic pipe binding unit, a back metallic pipe binding unit and a plurality of metallic pipes coated with catalysts which comprise one or several of copper oxide, chromic oxide, manganese oxide and nickel oxide, silveng unit, a back metallic pipe binding unit and a plurality of metallic pipes coated with catalysts which comprise one or several of copper oxide, chromic oxide, manganese oxide and nickel oxide, silver and palladium. The metallic pipes are adopted by the oil smoke purifier as carriers of the catalysts to be favorable for circulation of oil smoke, thus the oil smoke can be discharged to the outdoorr and palladium. The metallic pipes are adopted by the oil smoke purifier as carriers of the catalysts to be favorable for circulation of oil smoke, thus the oil smoke can be discharged to the outdoors easily. Meanwhile, the metallic pipes can be heated easily to enable the catalysts to quickly achieve the temperature needed by reaction. The chemical catalytic method is adopted to convert oil smoks easily. Meanwhile, the metallic pipes can be heated easily to enable the catalysts to quickly achieve the temperature needed by reaction. The chemical catalytic method is adopted to convert oil smoke

Description

technical field [0001] The invention belongs to the technical field of oil fume purification in the catering industry, and in particular relates to an oil fume purification processor suitable for an upper-row range hood. technical background [0002] With my country's reform and opening up, the catering industry is booming. The oil fumes emitted by restaurants, canteens, and restaurants pollute the surrounding air, especially in large cities or areas where the catering industry is concentrated. These gases have seriously endangered the health of residents, and have attracted great attention from the state, and issued the catering industry oil fumes. Emission standards, it can be seen that it is imperative to strengthen the management of oil fume in the catering industry. [0003] At present, the purification technologies of oil fume include inertial separation, electrostatic precipitation, fabric filtration, liquid washing, etc., almost all of which deal with oil fume by ph...
