Olfactory sensor array detection equipment and artificial olfactory device

Abstract

The invention relates to the technical field of environmental protection of air pollutant monitoring and provides olfactory sensor array detection equipment and an artificial olfactory device. The detection equipment comprises an air inlet channel, a test box, an exhaust pipe, a working power supply, a data acquisition card and a PC (Personal Computer), wherein a Y-shaped air inlet pipe and two air inlet chambers are arranged in the test box; multiple containing chambers are arranged in the air inlet chambers; a single sensor is arranged in each containing chamber; and the multiple sensors form a sensor array. The detection equipment can achieve the effects of monitoring various harmful gases in volatile organic compounds and accurately calculating the content of the various harmful gases in the volatile organic compounds (VOCs). The artificial olfactory device comprises a sampling unit, a signal processing and pattern recognition analysis unit, and the olfactory sensor array detection equipment. The artificial olfactory device is applicable to whole-process online spraying VOCs monitoring, and the VOCs and organic pollutants in the spraying process can be rapidly and accurately monitored.

Description

technical field [0001] The invention relates to the technical field of environmental protection for air pollutant monitoring, in particular to an olfactory sensor array detection device and an artificial olfactory device. 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...

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
