Abstract

The invention discloses a high-efficiency volatile organic matter online monitoring system. The high-efficiency volatile organic matter online monitoring system comprises a sampling probe system, a back flushing system, a preprocessing system, an online chromatographic instrument, a PLC control system, a hydrogen generator, an air generator, a high-purity nitrogen generator, a data processing system and a data acquisition instrument, wherein the online chromatographic instrument is in communication connection with the data processing system, the data processing system is respectively in communication connection with the data acquisition instrument and the PLC control system, and the PLC control system is respectively in communication connection with the sampling probe system, the back flushing system, the preprocessing system, the hydrogen generator, the air generator, the high-purity nitrogen generator and the DCS. By adopting the high-efficiency volatile organic matter online monitoring system, not only can a content of volatile organic matters contained in waste gas be accurately measured, but also dust attached inside a probe and at the outer side of a filter can be effectively removed in a blowing manner; and moreover, condensed water can be avoided, the measurement accuracy can be effectively improved, and meanwhile the entire processing period is relatively short.

Description

technical field

[0001] The invention relates to the technical field of online monitoring systems, in particular to an efficient online monitoring system for volatile organic compounds. Background technique

[0002] With the development of the economy, there are more and more types of enterprises, and among many enterprises, the emissions of some enterprises will seriously pollute the environment, such as oil refining enterprises, pharmaceutical enterprises, spraying enterprises, chemical enterprises, automobile enterprises, semiconductor enterprises, manufacturing enterprises, etc. Leather companies, foundry companies, and oil storage, transportation, and gas stations, etc., the exhaust gas emitted contains a large amount of benzene series or non-methane total hydrocarbons or other characteristic volatile organic compounds. In order to reduce the volatile organic compounds in the exhaust gas For the content of volatile organic compounds, an exhaust gas treatment device is in...
