Eco kitchen fume purification and extraction system

Abstract

An eco kitchen fume purification and extraction system, comprises a fume extraction system which generates negative pressure by a negative pressure device to inhale fume in the kitchen into an air inlet and transmit fume in the pipeline; a fume condensation chamber which is equipped with a filter for cooling and condensing the fume inside; the fume condensation chamber is provided with a condensed air inlet; a ventilation device inhales the air in a ventilation space through a compression device which compresses and sends the air to a compressed air inlet of the vortex tube; a low-temperature air outlet of the vortex tube is connected to the condensed air inlet of the fume condensation chamber; the fume condensation chamber cools down the internal temperature through the low-temperature gas generated by the vortex tube, the filter is kept in a low-temperature environment; the fume is cooled and collected when passing through the low-temperature filter, thereby greatly reducing the amount of oil fume emissions.

1 . An eco kitchen fume purification and extraction system, comprising:
 a fume extraction system with an air inlet located in the kitchen, which generates negative pressure by a negative pressure device to inhale fume in the kitchen into an air inlet and transmit fume in the pipeline;   a fume condensation chamber which is equipped with a filter for cooling and condensing the fume inside; the fume condensation chamber is provided with a condensed air inlet;   a vortex tube;   a ventilation device inhales the air in a ventilation space through a compression device which compresses and sends the air to a compressed air inlet of the vortex tube; a low-temperature air outlet of the vortex tube is connected to the condensed air inlet of the fume condensation chamber;   the air in the ventilation space is inhaled into the compression device to generate high-pressure air and is sent to the vortex tube; the low-temperature air is generated from the low-temperature air outlet by the vortex tube and is transmitted to the fume condensation chamber to cool down the filter; the fume in the kitchen is inhaled into the condensation chamber through the negative pressure device; by cooling of the low-temperature air, the fume condenses and separates through the cooled filter; the separated air is discharged from the air outlet of the fume condensation chamber.
