However, the volatilization of lampblack and oil accounts for 2%~4% of the total oil consumption, which can be corrected.

Or if the owner can provide relevant parameters, it is easier to calculate.

Generally, the fume purifier is installed, and the operation and maintenance work can meet the emission standards.

Send an example for your discussion:

The kitchen of this project has just built a catering industry with four cookers. According to the emission standard of cooking fume for catering industry (GB 18483-200 1), it belongs to medium-sized catering industry, and the average consumption of edible oil is 0.03kg/ person. If the number of diners is 20 and the daily passenger flow is 400, the daily fuel consumption is 12.6kg/d and the annual fuel consumption is 4.54 t/a. ..

According to the analogy investigation, under different combustion and explosion conditions, the smoke concentration and volatilization amount in the oil fume are different. The average volatile amount of oil accounts for 2.83% of the total oil consumption. After accounting, the oil fume output of this project is 0.36kg/d, and the annual oil fume output is 0.130t/a. If the cooking time is 7h/d, the oil fume emission of this project is 0.05 1kg/h, and the oil fume emission concentration is 2.55mg/m3 (calculated by the air volume of 20000m3/h). It exceeds the standard limit of 2.0mg/m3 for the maximum allowable emission concentration of cooking fume in the Standard for Cooking Fume Emission (GB 18483-200 1). If discharged directly, it will have an impact on the surrounding environment. It is suggested that two sets of electrostatic oil fume purification equipment be used to purify the oil fume, and the purification efficiency is 90%. After purification, the emission concentration of oil fume is 0.26mg/m3, and the emission is 0.013t/a. ..
