Development and application of fume control technology in the catering industry



Soot purification equipment is mainly used in coastal cities, tourist cities, provincial capital cities and large cities where the catering industry is developed. Small and medium-sized cities have also begun to have a certain amount of applications. The installation and application of fume purification equipment in several cities in Beijing, Shanghai, Guangzhou and Zhejiang is relatively popular, and the overall situation is good. The large-area installation and application of soot purification equipment in various regions is mainly driven by environmental protection policies and regulations. Most of the food and beverage owners are passively installed with lampblack purifiers . The local environmental law enforcement supervision departments have strengthened the control of the cooking industry and the daily operation supervision, which is still the leading influencing factor for the application of the soot purification equipment in the future.



The survey shows that several types of soot purification technologies widely used at present can basically meet the market needs of the fume management of the catering industry. The field surveillance and laboratory testing, can meet emission standards and "cooking fume purification equipment technical requirements and test specification (Trial)" (HJ / T62 - 2001 ) requires, fume purification effect is obvious, the majority of users of the product quality and after-sales service Satisfied.



The actual application of the fume purification equipment is mainly composed of electrostatic type, mechanical filter type, wet type, and composite products composed of the above three technologies. Among the fume purification equipment manufacturers that applied for review, electrostatic type ( including electrostatic composite type ) accounted for about 58 %, mechanical type accounted for about 26 %, and wet type ( including wet composite ) accounted for about 16 %. From the analysis of market users, electrostatic ( including electrostatic composite ) applications are the most common, accounting for about 80 % of the market , wet and mechanical accounts for about 20 % of the market .
