Fuel gas collecting and haze eliminating double-fan system

Abstract

The invention discloses a fuel gas collecting and haze eliminating double-fan system. The system comprises a casing, a water cooling device, a negative pressure plant fiber purifying device, a fan anda positive pressure purifying silencer, wherein the water cooling device, the negative pressure plant fiber purifying device and the fan are all mounted in the casing; the water cooling device is mounted at the lower part of the casing; the negative pressure plant fiber purifying device is mounted in the middle of the casing; the fan is mounted at the upper part of the casing; a main air inlet isformed in the lower end of the casing; an air outlet is formed in the upper end of the casing; and the positive pressure purifying silencer is connected with the air outlet. The system ensures that two sets of systems which can be operated independently are mounted into one box body, and cools down fuel gas and a fireproof baffle in front of a kitchen ventilator. The system is provided with the plant fiber purifying device, and can purify cooled fuel gas and prevent overheat and combustion of the plant fiber purifying device caused by overheated fuel gas. The system is compact in body structure, high in suction and good in purification effect, ensures that water in a cooling water tank can be recycled after being heated, and is fireproof and good in energy-saving effect.

Description

technical field [0001] The invention relates to an oil fume purifying device, in particular to a double fan for collecting smoke and removing haze. 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 fumes. 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 the range hood or ...
