Volatile organic compound purification device with sintered metal powder as carrier

Abstract

The invention discloses a volatile organic compound purifying device adopting sintered metal powder as a carrier. The volatile organic compound purifying device comprises a fan, a gas collection cover and a sintered metal powder catalytic oxidation filtering unit, which are sequentially connected with one another, wherein the sintered metal powder catalytic oxidation filtering unit is internally provided with sintered metal powder filtering cores, a base material of the sintered metal powder filtering cores is formed by sintering 316L stainless steel powder at a high temperature, a layer of compact oxidation film is coated on the sintered base material, an Al2O3 coating is coated on the oxidation film, active components, platinum and V2O5, of a catalyst on the coating are completely and uniformly attached to the catalyst filtering core carrier in an ultrafine particle form, and finally, the catalyst filtering core carrier is sintered at a high temperature. Through the catalytic oxidation effect, the oxidation speed of volatile organic compounds and O2 can be enhanced, so that volatile organic pollutants are oxidized to water and carbon dioxide, and the amount of the discharged volatile organic compounds is far lower than the national emission standard after the volatile organic exhaust gas is processed.

Description

technical field [0001] The present invention relates to a volatile organic compound purification device, in particular to a volatile organic compound purification device using sintered metal powder as a carrier. Background technique [0002] Volatile organic compounds refer to volatile hydrocarbons and their derivatives, mainly including hydrocarbons, aromatic hydrocarbons, alcohols, ketones, lipids, amines, organic acids, etc. The emission hazards of volatile organic compounds mainly include: (1) In sunlight, NO x Photochemical reactions will occur with volatile organic compounds in the atmosphere to generate photochemical smog such as ozone, peroxynitroacyl (PAN), aldehydes, etc., causing secondary pollution, irritating human eyes and respiratory system, and endangering human health. At the same time, volatile organic compounds can also harm the growth of crops, and even lead to the death of crops. (2) Most of the volatile organic compounds are poisonous and have a foul ...

AI Technical Summary

Problems solved by technology

The emission hazards of volatile organic compounds mainly include: (1) In sunlight, NO x Photochemical reactions with volatile organic compounds in the atmosphere will generate photochemical smog such as ozone, peroxynitroacyl (PAN), aldehydes, etc., causing secondary pollution, irritating human eyes and respiratory system, and endangering human health

At the same time, volatile organic compounds can also harm the growth of crops, and even lead to the death of crops

(2) Most of the volatile organic compounds are poisonous and have a foul smell, which can cause people to suffer from cumulative respiratory diseases

At high concentrations, it can sometimes cause acute poisoning and even death

Some volatile organic compounds can cause cancer

(3) Most volatile organic compounds are flammable and explosive, and may cause fire and explosion when discharged in high concentrations

However, the above methods all have disadvantages such as low processing efficiency and stable operation.
