Problems solved by technology

The swirl tube of patent CN01120562.8 has a spiral channel inside, and the structure is complex, and oil accumulates in the tube after a long time, and the patent does not propose a suction and discharge scheme, which is difficult to implement
Patent CN92102246.8 and patent 91108847.4 are split type of fan and swirl tube, the suction pipeline is long, the loss of vacuum degree is large, and the suction force is affected
[0006] Another patent, application number 200610039320.3, is an oil fume separator, in which the cyclone separation tube has a large resistance and is a single inlet, and the flow field in the cyclone separation tube has poor symmetry, which affects the separation and purification effect

Abstract

The invention relates to a method for discharging and purifying smokes and a device thereof. The device consists of one or more than one rotational flow separation tube, a fan, an inner drum, an outer drum, a clapboard, a smoke cover, a rolling curtain and an oil collection cup, wherein, the rotational flow separation tube is provided with two or more than two symmetric inlets which are vertically arranged inside the inner round drum. The clapboard, the outer wall of the rotational flow separation tube and the inner drum form a smoke annular spout absorption channel. The fan is arranged on the top of the rotational flow separation tube. An inlet of the fan is connected with an air outlet of the rotational flow separation tube. The lower part of the rotational flow separation tube extends the smoke cover to the lower part of the smoke cover. An oil outlet positioned at the bottom of the rotational flow separation tube is sleeved with the oil collection cup. The invention has the advantages that the invention is designed based on the air dynamics, so that the smoke flows smoothly, with small resistance and high absorbing and purifying efficiency; and the invention adopts a method of medium free separation, thereby ensuring permanent smooth and continuously ensuring the high operation efficiency of a smoke extractor.

Description

technical field [0001] The invention relates to a method and equipment for removing and purifying oil fume. Background technique [0002] The range hoods currently on the market are basically impeller-type suction and inertial separation of oil droplets in the range hood. The installation height, that is, the distance between the suction port and the cooking surface is generally 600-750mm. [0003] Due to the strong attenuation characteristics of the suction wind speed outside the suction port, when the wind speed of the suction port is 20m / s, the effective suction distance is only twice the diameter of the suction port. For the existing range hood, if the diameter of the suction port is 200mm and the suction wind speed is 4m / s, the effective suction distance is less than 200mm. In order to improve the suction effect, generally use your brains on the installation height of the hood and range hood. For example, the front panel of the hood of patent CN200510024074.X adopts t...
