Artificial smelling apparatus and organic pollutant control device

Abstract

The invention provides an artificial smelling apparatus, which relates to the technical field of the environmental protection of air pollutant monitoring. The artificial smelling apparatus comprises a sampling unit, a smelling sensor array detection unit, a signal processing and model identification and analysis unit and an integration control unit. The artificial smelling apparatus can realize a rapid detection process from sample collection, test, analysis and modeling to the summarizing of pollution results, and is reasonable in structure design, convenient in operation, high in working efficiency, capable of accurately monitoring the pollution degree of a sprayed volatile organic pollutants, capable of overcoming the defects that the existing VOCs detection apparatus is single in detection component, high in cost and the like, and wide in application range. The invention also provides an organic pollutant control device. The organic pollutant control device comprises an artificial smelling apparatus, the concentration of organic pollutants in the spraying process can be rapidly detected by virtue of the artificial smelling apparatus, the data analysis can be carried out in time, the organic pollutants can be eliminated when the concentration is detected to be out of standard, and the safety and reliability of an operation environment is ensured.

Description

technical field [0001] The invention relates to the technical field of environmental protection for air pollutant monitoring, in particular to an artificial olfactory device and organic pollutant control equipment. Background technique [0002] In recent years, my country's air quality has deteriorated seriously, regional smog and ozone pollution incidents have occurred frequently, and long-term large-scale emissions of volatile organic compounds (volatile organic compounds, VOCs) are one of the main factors. According to statistics, VOCs in cities mainly come from exhaust emissions from fixed pollution sources, accounting for about 55.5% of the total man-made emissions. Due to the diversification of the product structure of enterprises with coating processes, the types and shapes of coating materials, and the processes used in the coating process are also different, resulting in different VOCs emission links and emission characteristics. Effective monitoring methods for VO...

Problems solved by technology

[0004] The off-line detection method of gas chromatography, its equipment is expensive, the test cost is high, and it needs to be operated by professionals, which cannot meet the requirements of on-site detection, and the off-line method has poor timeliness and cannot reflect the change of gas concentration in time. The process is easy to lead to sample loss and cross-contamination, and the testing process is cumbersome and costly

[0005] The online monitoring sensor method only measures the total amount of VOCs and cannot fully reflect the emission of coating pollutants
