An exhaust kitchen with oil fume purification function

Abstract

The invention discloses an exhaust kitchen with a fume purification function. The exhaust kitchen comprises a kitchen side wall, a kitchen ceiling, an extraction fan, a built-in exhaust device, a gasstove cauldron stove and an ionization purification device. According to the exhaust kitchen, both the upper direction and the lower direction are taken into consideration for the fume extraction, theefficiency of the fume extraction is improved greatly, and the suction is cleaner. In addition, lower fume can be further purified through the additionally-arranged ionization purification device, and meanwhile part of purified air sucked from the upper portion of the kitchen can be guided into a cylindrical ionization purification device mounting seat with a partition plate to form a back flow,so that the temperature of the ionization purification device is lowered greatly, the use condition of the exhaust kitchen is guaranteed, and the service life is prolonged.

Description

technical field [0001] The invention relates to an exhaust kitchen with oil fume purification function. Background technique [0002] The kitchen is a basic part of the house and the main place for people to cook. Due to the burning of various civil fuels, cooking fume and domestic garbage, the kitchen has become the "hardest hit area" of the residence, and the kitchen has also become one of the important sources of indoor air pollution in residential buildings. Kitchen exhaust gas is the main polluting gas in the kitchen. It includes two types: one is the exhaust gas released during the fuel combustion process, and the other is the substances produced by a series of physical and chemical changes of food and oil at high temperature. The two substances mix and spread rapidly in space, endangering people's physical and mental health. [0003] The most important components in cooking fumes are alkanes and alkenes, followed by organic acids, aldehydes and polycyclic aromatic h...

Problems solved by technology

However, there are several disadvantages: firstly, there are various exhaust pipes and windproof caps connected by users themselves, which damage the appearance of the building's facade; secondly, the oily fume discharged from the kitchen on the lower floor will enter the indoors of the residents on the upper floor, causing pollution; thirdly, When encountering high-speed head-on wind, there will be poor exhaust or backflow

[0009] First, although the oily fumes on the upper part of the exhaust kitchen are sucked, all the smoked oily fumes are collected and discharged through a pipe, that is, the fifth communication pipe 19, which increases the oil fume flow in the fifth communication pipe. In the actual cooking process, the power consumption of the exhaust fan will be relatively large, especially the power consumption of the first auxiliary exhaust fan 17 is too large;

[0010] Second, although most of the oil fume has been purified, the concentration of oil fume directly drawn from the lower part of the kitchen is relatively high, and there are still many harmful pollutants, which need further purification, while the oil fume directly drawn from the upper part of the kitchen has less harmful substances , after primary filtration can basically meet the requirements of environmental protection, how to meet the above two requirements
