Background

With the improvement of social productivity and the living standard of people, the contradiction between the oil smoke emission of catering kitchens and atmospheric environmental pollution is increasingly sharp; along with the increase of kitchen oil smoke discharge, the oil collection in the smoke exhaust pipeline is more and more, causing serious fire-fighting hidden trouble. The existing household range hood is basically of a direct-suction direct-exhaust type, namely, oil smoke is sucked out of a kitchen and directly discharged into an oil smoke pipeline of a building, so that the environment is polluted, and potential safety hazards are buried.

At present, the kitchen fume purification mode mainly adopts an alkali liquor wet washing method, a high-voltage electrostatic purification method, a photochemical catalytic decomposition purification method, a physical filtration method and the like. The high-voltage electrostatic method has good purification effect, but is troublesome to maintain and clean; the photochemical catalysis method requires a large space, a pipeline with the length of 30 meters at least is convenient for installing an ultraviolet light tube, and ultraviolet light for catalysis causes cancer and needs to be tightly sealed. Physical filtration method, poor purification effect and troublesome cleaning!

Therefore, although the technology of purifying the oil smoke is mature now and various purifiers are provided, the problems exist.

The Chinese patent with the patent number of CN93108618.3 discloses a liquid washing method, wherein a liquid pump is used to establish a circulating system of cleaning liquid, kitchen oil smoke is introduced into the cleaning liquid before being discharged, so that the kitchen oil smoke is fully mixed and absorbed by the cleaning liquid, and then the kitchen oil smoke is discharged to the atmosphere after gas-liquid separation. The device occupies a large area, the ventilation quantity is insufficient, and the liquid forms secondary pollution.

The Chinese patent with the name of 'liquid suction method range hood' and the patent number of CN02122338.6 discloses a liquid suction method range hood, which at least comprises a fan and a channel, wherein the channel of the fan is connected with a liquid range hood device, the liquid range hood device comprises a container, the container is used for containing liquid with the performance of absorbing or adsorbing oil smoke, the container can be a communicated container or a non-communicated container, the container (which can comprise a space above the communicated container or the non-communicated container) is separated to form a smoke inlet channel, a smoke outlet channel and a smoke communication channel, the smoke communication channel is arranged below the smoke inlet channel and the smoke outlet channel, and the smoke inlet channel and the smoke outlet channel are communicated through the smoke communication channel. The smoke inlet channel can be connected with the channel to suck smoke or can directly suck smoke. The flue gas outlet channel is connected with a channel of the fan to discharge flue gas. The oil fume purification device has the advantages that the contact area of gas and liquid is not enough, the purification efficiency is low, no high-pressure water pump is used for atomization circulation, secondary emission pollution is caused by waste water, the volume is large, the installation cost is high, and the emission requirements on the existing oil fume national standards and regional landmarks cannot be met.

The working process and the principle of the device are as follows:

the oil fume purifier comprises a front-end gas-liquid mixing processor 1, under the action of a draught fan 5, kitchen oil fume is sucked into a single channel through an air inlet 1-3 on the right side of equipment, and a spray pipeline 1-2 is adopted to carry out gas-liquid mixing treatment on the oil fume, so that harmful substances in the oil fume and the waste gas are comprehensively captured. The gas and the liquid in the upper layer flow guide channel and the lower layer flow guide channel collide with the labyrinth channel formed by the plurality of baffle plates for a plurality of times, harmful substances are absorbed, the particles and the circulating emulsion in spraying atomization form a mixture, and most of the oil smoke, carbon particles and non-methane total hydrocarbon are purified in the process. The angle set when the gas-liquid mixture passes through the first bottom baffle plate and the second bottom baffle plate is used for carrying out dry-wet separation according to the wind direction principle. The gas after the diversion is sent to the gas-liquid separation equipment 4 for treatment, and then the gas enters the tail end auxiliary equipment for complete purification and then is discharged. The oil-water mixture flows into the emulsification tank 8 containing the compatible oil through the water return pipe 13, and the plurality of emulsification tank guide plates 10 in the emulsification tank 8 fully emulsify and adsorb the harmful substances in the mixture through circulating power. When the circulation liquid is supersaturated, the floating oil floating on the liquid level is stored into the oil storage tank 11 through the floating oil pipe 12 by the specific gravity of the liquid, and does not participate in the circulation system. Other circulatable liquid is sucked into the inlet of the water pump 9 from the water outlet on the partition plate, the circulating liquid enters the water pump 9 for high-pressure atomization spraying, and the equipment integrally forms a circulation. Meanwhile, equipment can be added at the tail end: such as high voltage static electricity, low temperature plasma, active carbon, photo-oxygen catalysis, etc.
