Abstract

The invention discloses a smoking, frying and baking oil fume pollutant emission reduction device which comprises a purification box shell, an atomizer, an ultrasonic coagulation unit and an electrostatic deposition unit which are sequentially arranged in the purification box shell from the air inlet to the air outlet, and the air outlet end of the purification box shell is connected with a box body, a photocatalytic oxidation unit, a plasma catalytic oxidation assembly and a tail end filtering unit are arranged in the box body, an exhaust port is formed in the tail side of the box body, flow equalizing plates are arranged on the two sides of the ultrasonic coagulation unit, and the flow equalizing plates are longitudinally arranged in the purification box shell in a sliding mode. The device comprises an ultrasonic coagulation unit, an electrostatic deposition unit, a photo-catalytic oxidation unit and a tail end filtering unit, the problem that conventional purification equipment is low in emission reduction effect on fine particulate matters in oil smoke is solved, and meanwhile, efficient purification of VOCs in the oil smoke is achieved.

Description

technical field [0001] The invention belongs to the field of pollutant control in food processing, and in particular relates to a compound emission reduction device for processing pollutants in smoked, fried and grilled food based on the principle of ultrasonic condensation and synergistic photocatalytic oxidation. Background technique [0002] Pollutants in smoked, fried and baked food processing are the volatilized oils and fats, organic matter and its fuel, and the products of thermal decomposition, oxidation, thermal polymerization and cracking of the food itself during food processing. The composition is extremely complex, mainly including fuel combustion products, oil droplets, short Aldehydes, ketones, alkanes, alkenes, alcohols, esters, carboxylic acids, aromatic hydrocarbons, and particulate matter, etc., when smoked, fried and grilled food fume pollutants are directly discharged into the atmosphere without purification treatment, of which aerosol particles, VOCs in ...
