Kitchen ventilator positive pressure dust collecting system

Abstract

The invention discloses a kitchen ventilator positive pressure dust collecting system. The kitchen ventilator positive pressure dust collecting system comprises a positive pressure dust collecting binand further comprises first purification devices and second purification devices, all of which are arranged in the positive pressure dust collecting bin. The positive pressure dust collecting bin isin a cylindrical shape and is vertically arranged. The multiple first purification devices and the multiple second purification devices are arranged and are vertically arranged in a staggered manner,and a gap is formed between each first purification device and the corresponding second purification device adjacent to the first purification device. Cooking fume pollution gas enters from the lowerend of the positive pressure dust collecting bin and penetrates the first purification devices and the second purification devices, all of which are arranged in the staggered manner, cooking fume gasredistribution is formed in the gaps between the first purification devices and the second purification devices, and smoke can evenly circulate in each first purification device and each second purification device. Pollutants in cooking fume can be sufficiently adsorbed. The first purification devices and the second purification devices can be selected to be increased or reduced according to the needed smoke purification amount, and therefore the effect that the pollutants in the cooking fume gas can be completely purified can be achieved.

Description

technical field [0001] The invention relates to an oil fume purification system, in particular to a positive pressure dust collection system for an oil fume machine. Background technique [0002] Cooking fume is formed by a series of physical and chemical changes in edible oil and food under high temperature conditions. When the edible oil is heated to 170°C, a small amount of oil fume begins to appear. As the temperature rises, the decomposition rate of the oil accelerates. When the temperature reaches 250°C, a large amount of cooking fume will be produced. In our country's diet, most foods need to be fried, fried, boiled, fried, etc. at high temperatures, and the oil temperature is often above 250°C, which easily produces a lot of cooking fume. When the stove is working, the oil fume generated in the hearth will not only heat the kitchen utensils, but the excess heat will dissipate into the room in the form of heat radiation, and be directly discharged to the outside by t...
