Device and method for online measuring content of volatile organic compounds

Abstract

The invention discloses a device for online measuring the content of volatile organic compounds and a method for online measuring the content. According to the method, the problem that the content of volatile organic compounds cannot be continuously monitored by a current method can be solved. The measuring device comprises a reaction cell, a light source system, a gas circulating system and a detecting system, wherein the gas circulating system is divided into two paths; the first path of the gas circulating system comprises a first gas vacuum pump and a first silicone tube; the second path of the gas circulating system comprises a second gas vacuum pump and a second silicone tube; one end of the first silicone tube is connected to a hose, an injection chamber and the first gas vacuum pump; the other end of the first silicone tube is communicated with the reaction cell; the hose is connected with the reaction cell. According to the device and the method, the content of volatile organic compounds (VOC) can be detected online, and the degradation rate of photoreaction and dark reaction of some photo-catalytic material can be evaluated; NOx, SOx, benzene series, organic chloride, Freon series, organic ketone, amine, alcohol, ether, ester, acid, aldehyde and petroleum hydrocarbon and other volatile organic compounds can be detected online.
