Harmful gas purifying method, there are four: combustion, condensation, absorption and adsorption. Physical absorption and chemical absorption difference: the former is generally no significant chemical reaction, can be seen as a simple physical dissolution Hangzhou kitchen smoke Engineering Which is good, is reversible, it does not change the nature of the gas is absorbed by desorption; the latter It is associated with significant chemical reaction, and the efficiency is higher than the former engineering hotline Hangzhou kitchen smoke, especially when dealing with low concentrations of gas. In absorbing operation Hangzhou kitchen exhaust engineering company, it is absorbed by the gas absorbing substance called gas phase does not participate in gas absorption is called falling gas absorbing liquid is called absorber. Precipitator Efficiency: the ability to capture dust filter from the gas stream. Full efficiency: The dusty gas through the precipitator dust collecting accounts into the percentage of total dust precipitator. Fractional efficiency: dust removal of a particular size range dust. Split diameter (dc50): particle filter efficiency rating of 50%. Fuyang area kitchen exhaust engineering | Hangzhou kitchen ventilation engineering | Xingda ventilation supplied by Hangzhou Xingda ventilation equipment.
