Abstract

A material for high-efficient removal of non-methane total hydrocarbon from oil fume is disclosed. The invention specifically relates to a high-performance material for adsorption and purification ofnon-methane total hydrocarbon in cooking oil fume, and belongs to the technical field of oil fume purification. The invention is characterized in that a multifunctional honeycomb-shaped high-specificsurface area activated carbon material is used as a carrier to simultaneously impregnate an active component and an efficient antibacterial component; and through solid-liquid separation and drying, an MHCC high-performance honeycomb material is prepared. The load capacity of the active component is 0.001-10 wt%, and the content of the efficient antibacterial component is 0.001-1 wt%. by using 900g of the MHCC high-performance honeycomb material at normal temperature at the air volume of 300-700 m<3> / h, the removal efficiency of 0.7-3.2 mg / m<3> non-methane total hydrocarbon in the 30 m<3> environment can reach 70% within 15 minutes. The material of the invention is suitable for dining places such as hotels, restaurants, hotels, resorts, central kitchens and canteens, as well as cooking appliances such as gas stoves, microwave ovens, ovens and steamers.

Description

technical field [0001] The invention relates to a non-methane total hydrocarbon material in high-efficiency oil fume removal, specifically a high-performance material obtained by impregnating active components and high-efficiency antibacterial components with a multifunctional honeycomb-shaped high-specific surface area activated carbon material as a carrier. Oil fume purification technology field. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, the number and scale of the catering industry have grown rapidly. However, a large number of oil fume pollutants are also produced at the same time, which endangers human physical and mental health and affects environmental air quality. Food fume pollution has become the third largest source of air pollution after industrial pollution and traffic pollution. Since the traditional cooking methods in our country mainly use operations such as frying, frying and...
