1. What are the harmful chemical constituents of oil fume? What harms people?
Edible oil and food undergo chemical reactions under high temperature conditions. The products of these reactions are mainly aldehydes, ketones, hydrocarbons, fatty acids, alcohols, esters, lactones, heterocyclic compounds, aromatic compounds, and the like. Scientific experiments show that these compounds have great harm to human health, such as: inhalation of high-concentration oil fume can cause lung diseases and tissue cell damage, and lung capacity decreases; oil fume smoke affects the body's cellular immunity and macrophage functions, causing The immune function of the human body is reduced; there are substances that can cause gene mutation, DNA damage, chromosome damage, etc. in the soot smoke, which are potentially carcinogenic.
2. What are the common treatment methods for oil fume? What are the characteristics of each?
The currently used oil fume treatment methods are mainly mechanical methods, filtration methods, spray methods and electronic methods. The mechanical method is a separation method that uses smoke particles that are relatively larger than the air mass. Gravity, inertial force, and centrifugal force are used. Due to the wide range of particle size distribution of oil fume, this method has very weak treatment capacity for finer particle size smoke and has a low purification effect. The filtration method has been used in domestic oil fume purification. It has the disadvantages of high requirements for filter paper (net), frequent replacement (or cleaning), large system resistance, and small processing capacity.
