Background

The oil fume of the existing range hood is purified mainly by a centrifugal deoiling technology, but the purification effect of the mode is not ideal enough, the structure is complex, and the failure rate is high. The invention is designed aiming at the defects of the prior oil fume purification technology.

Disclosure of Invention

The utility model provides a device of purifying oil smoke with ultrasonic atomization, concatenates a gas mixing chamber on lampblack absorber exhaust pipe, and gas mixing chamber intercommunication ultrasonic atomization generator, oil smoke mixes with steam after, in reentrant cooling sedimentation tank, has water in the cooling sedimentation tank, the oil smoke integument is cooled down, and oil smoke particle wherein is depositd in the aquatic, and surplus clean gas overflows from the cooling sedimentation tank, and the oil smoke is purified into clean gas. This scheme of adoption, simple structure, it is with low costs, purification efficiency is high, and the blowdown is few, and sewage treatment is simple.

The specific technical scheme adopted by the invention is that a gas mixing cavity is connected in series on a smoke exhaust pipe of the range hood, the gas mixing cavity is a closed space and is simultaneously communicated with an ultrasonic atomization generator, the ultrasonic atomization generator atomizes water into steam by utilizing high temperature, the gas mixing cavity is communicated into a cooling sedimentation tank through a gas mixing pipe, water is contained in the cooling sedimentation tank, an air exhaust fan is connected in series on the gas mixing pipe, the gas outlet end of the gas mixing pipe is communicated with a bubble cutter, the bubble cutter consists of a plurality of layers of filter screens, the filter screens are separated from one another by a certain distance, the bubble cutter is arranged below the water surface in the cooling sedimentation tank, and an exhaust pipe is arranged at the top end of the cooling sedimentation tank; the oil smoke passes through a fan of the range hood and enters the gas mixing cavity through a smoke exhaust pipe, the ultrasonic water mist also enters the gas mixing cavity, the oil smoke and the ultrasonic water mist are mixed in the gas mixing cavity to become smoke-steam mixed state smoke, the smoke-steam mixed state smoke enters the cooling sedimentation tank through the air exhaust fan, the cooling sedimentation tank has water, the outlet end of the gas mixing pipe is communicated with a bubble cutter, the bubble cutter is soaked in the water, the smoke-steam mixed state smoke can only enter the water through fine meshes of the bubble cutter, the smoke-steam mixed state smoke is forcibly cut into fine bubbles by the bubble cutter, the fine bubbles are cooled and precipitate smoke dust particles in the water, the rest part becomes clean gas, and the clean gas is exhausted through the exhaust pipe.
