it can play a filtering role.

because oil fume is a large amount of thermal oxidation decomposition products produced by edible oil and food at high temperature. The specific heat capacity of water is large, which can absorb a lot of heat and re-liquefy the lampblack. Moreover, the oil fume contains more than 221 kinds of chemicals, including aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, esters, lactones, heterocyclic compounds and so on. Water can absorb water-soluble substances in oil fume. Extended information

Benefits of using water filtration:

Water-soluble substances usually contain polar groups such as -OH, -SO3H, -NH2, -NHR, -COOH, etc. or carbon chains that are not too long. Water is the cheapest solvent with wide sources and no pollution. Water-soluble polymers are soluble in water because hydrogen bonds are formed between water molecules and polar side groups of polymers.

Hazards of lampblack:

1. Too high a temperature

It is a habit in the crude oil era to put vegetables after lampblack. When cooking with today's pure oil, the temperature when lampblack is emitted is already too high, which is not only harmful to oil, but also harmful to vitamins. Lampblack itself is a serious air pollution.

2. There are many carcinogens

There are many harmful substances in the oil fume, including acrolein, benzene, formaldehyde, crotonaldehyde, etc., all of which are toxic and carcinogenic. At present, studies at home and abroad have confirmed that oil fume is a risk factor for lung cancer.

3. Damage to respiratory system

When the oil is burned to 1.51 degrees Celsius, the glycerol in it will generate acrolein, which has a strong pungent taste and strong stimulation to nose, eyes and mucous membranes. When the oil is burned to "spit fire", it will not only generate acrolein, but also produce aggregates, which will lead to cell chromosome damage and cancer.
