Abstract

The invention discloses a smoke exhaust ventilator capable of purifying air. The smoke exhaust ventilator comprises a shell and lampblack pumping holes, wherein the lampblack pumping holes are formed in the bottom surface and the side faces of the shell; the shell is provided with a centrifugal fan arranged in the shell; the centrifugal fan is arranged in a turbine shell to enable air entering the turbine shell to be centrifuged; an oil stain flow guide hole is formed in the bottom of the turbine shell; at least one venting gap is arranged on the upper side face of the smoke exhaust ventilator and is connected with a catalyst layer. According to the invention, through arranging the catalyst layer at an exhaust port, acrolein and other organic pollutants in lampblack are degraded into carbon dioxide, and various pollutants are reduced to ppm scale, so that lampblack is effectively purified.

Description

technical field [0001] The invention relates to the field of oil fume removal and purification, in particular to a range hood with air purification function. Background technique [0002] China is a big food country, and its cooking methods include frying, stir-frying and steaming. During the whole cooking process, a lot of oily smoke will be produced. [0003] Research has found that cooking fume is a large amount of thermal oxidation decomposition products produced by edible oil and food under high temperature conditions. When cooking, the fat is heated. When the temperature reaches the smoking point of edible oil at 170°C, the blue smoke of initial decomposition appears. As the temperature continues to rise, the decomposition speed accelerates. It has a pungent smell, and the particle size of oily fume is between 0.01 micron and 0.3 micron. Relevant departments analyzed the oil fume samples collected from residents’ households and found more than 220 kinds of chemical s...
