Abstract

The invention relates to a lampblack extraction and purification device. Most of the existing range hoods produce oily waste water and exhaust gas and require high operating costs and power consumption, and the extraction and purification effect also needs to be improved urgently. The oil fume extraction and purification device of the present invention comprises: a gas collecting hood, which has an air inlet and an air guide channel; a first gas collecting box is arranged downstream of the gas guiding channel in the flow direction of the flue gas, and the first gas collecting box is removed from the bottom. The wall and the box wall other than the above-mentioned one side box wall are provided with air exhaust holes and exhaust fans; the second air collecting box, which is arranged downstream of the first air collecting box in the flow direction of the above-mentioned flue gas, is connected with all the air boxes through the air exhaust duct. The air exhaust holes are connected; at least one section of the air exhaust duct is provided with a cooling mechanism; the air outlet is provided with a centrifugal fan. Through the above structure, the effect of exhausting and separating oil fume from the flue gas can be improved, and the power consumption is small. The device of the present invention is mainly used in domestic kitchens, catering operation rooms and other occasions.

Description

technical field [0001] The present invention relates to the exhaustion and purification of oily fumes in household kitchens, operating rooms of catering industry or food processing places. Specifically, the present invention relates to an extraction and purification device for oily fume especially used in catering industry or household. Background technique [0002] In the prior art, a top-suction range hood is generally used for extracting oily fume in the operating room of the catering industry or in the family kitchen, which is connected to a certain length of pipeline, and is used to send the collected smoke into the oily fume purification device installed in the flue. , after purification, it is discharged into the atmosphere (generally high-altitude discharge). In the top-suction oil fume extraction operation, the oil fume is collected in the higher area above the operating table and is directly blown or induced by the exhaust fan arranged on the airflow pipeline.
