Lampblack flue gas purification treatment material

Abstract

The invention discloses a lampblack flue gas purification treatment material. The flue gas purification treatment material is mainly prepared from a carbon-based component, an inorganic mineral adhesion component, an inorganic adsorption component, a noble metal catalyst component, a non-noble metal catalyst component and an auxiliary agent, wherein the content of each raw material is as follows in percentage by mass: 60 to 90 percent of the carbon-based component, 10 to 40 percent of the inorganic mineral adhesion component, 3 to 10 percent of the inorganic adsorption component, 0.02 to 0.12percent of the noble metal catalyst component, 0.5 to 20 percent of the non-noble metal catalyst component and 0.6 to 2.5 percent of the auxiliary agent. All the components are prepared into the multifunctional, efficient, long-effect, integrated, high-strength and low-attenuation lampblack flue gas purification treatment material according to a certain preparation technology. The composite material can be used for carrying out efficient and rapid absorption and catalytic decomposition on multi-component VOCs (Volatile Organic Compounds) with different types in lampblack flue gas generated ina kitchen. Meanwhile, the flue gas purification treatment material has the characteristics of low cost, low air resistance, low noise, low energy consumption and the like, and the blank of a current market that the purification efficiency on the lampblack flue gas VOCs of the kitchen is low is filled up.

Description

technical field [0001] The patent of the invention relates to a material for purifying cooking fume and smoke from kitchen range hoods, and belongs to the technical field of air purification. Background technique [0002] Oil fume is a large amount of volatile organic compounds (VOCs) produced by thermal oxidation and pyrolysis of edible oil and food under high temperature conditions. There are hundreds of pyrolysis products of different types of edible oil at high temperature. The main ones are The chemical composition is saturated hydrocarbons, unsaturated hydrocarbons, benzene series, polycyclic aromatic hydrocarbons, heterocyclic compounds, aldehydes, ketones, esters, etc., most of which are toxic and harmful substances, while benzene series, polycyclic aromatic hydrocarbons etc. are carcinogens. With the continuous improvement of my country's economic growth and people's living standards, oil fume pollution has increasingly become a major environmental problem that ser...

AI Technical Summary

Problems solved by technology

Among them, the purification of VOCs involves a wide variety of volatile components in the flue gas with large differences in properties, and it is impossible to use one technology to remove multiple components at one time, efficiently and at low cost

At present, the range hoods on the market are seriously lacking in the purification function of VOCs, basically there is no mature technology for VOCs purification, and there are defects such as complicated purification technology and devices, high operating costs, low purification efficiency, and immature technology.
