Oil smoke removing and discharging clean-up machine

Abstract

The invention relates to a method and equipment for removing and purifying oily fume, which is composed of one or more cyclone separation pipes, fans, inner cylinders, outer cylinders, partitions, fume hoods, rolling shutters and oil collection cups. Among them, the cyclone separation pipe has two or more symmetrical inlets and is vertically installed in the inner cylinder. The separator, the outer wall and the inner cylinder of the cyclone separation tube form an oil fume annular tornado suction channel. The fan is installed on the top of the cyclone separation tube. The inlet of the fan is connected with the outlet of the cyclone separation pipe. The lower part of the cyclone separation pipe stretches out to the bottom of the smoke hood, and the oil discharge port at the bottom is covered with an oil collecting cup. The present invention is based on the aerodynamic design, so that the oil fume flows smoothly, the resistance is small, the suction and purification efficiency is high, and the medium-free separation is adopted, never blocked, and the high-efficiency work of the range hood can be continuously ensured.

Description

Technical field [0001] The invention relates to a method and equipment for removing and purifying oil fume. Background technique [0002] At present, the range hoods on the market are basically impeller-type suction and inertial separation of oil droplets in the cooking fume. The installation height, that is, the distance between the suction port and the stove surface is generally 600-750mm. [0003] Since the suction wind speed outside the suction port has a strong attenuation characteristic, when the suction port wind speed is 20m / s, the effective suction distance is only twice the suction port diameter. 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 brain on the installation height of the hood and range hood. For example, the front panel of the hood of patent CN200510024074.X is made of transparent material...

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
