A rotating curtain type tornado range hood

Abstract

A rotating curtain type tornado range hood, including the range hood housing, and also includes an air multiplier air outlet ring, a turbo fan, an air multiplier inlet pipe, a static pressure box, an air curtain inlet pipe, an air curtain fan, and a rotating air curtain A power module composed of an air guide ring and an intelligent controller; an oil fume composite purification module composed of a filter screen, a shroud, an electrostatic capture unit and a catalytic oxidation unit; a waste oil utilization module composed of an oil tank and an oil collection box. The surrounding tangential airflow generated by the rotating air curtain air guide ring and the central ascending airflow generated by the air multiplier air outlet ring are coupled to form an artificial tornado flow field to achieve efficient extraction of oil fume; the oil fume composite purification module purifies the sucked oil fume After treatment, part of the purified flue gas returns to the static pressure box for system recycling, which reduces the environmental energy consumption caused by the large amount of indoor air being discharged to the outside; waste oil uses modular waste to treasure, turning waste oil into flower fertilizer and preliminary soap.

Description

technical field [0001] The invention relates to a range hood, in particular to a rotating curtain type tornado range hood. Background technique [0002] Kitchen fume is composed of submicron particles and gaseous pollutants. The particle size of these particles is small, usually within 200nm, and its quantity accounts for more than 80% of the total emission concentration. In addition, kitchen fumes contain a variety of carcinogens, which can cause great harm to the human body: Some people have found through research that cooking fumes can adversely affect the body's cellular immunity, macrophage function, and anti-tumor effects; the research results It is found that the cooking fume contains some toxic substances, which can cause gene mutation, DNA damage, chromosome damage and other phenomena, which are not only genotoxic, but also potentially carcinogenic. [0003] In addition, the traditional range hood sucks and discharges a large amount of indoor air to the outside, so...
