Volatile organic compound monitoring and sampling equipment

Abstract

The invention discloses volatile organic compound monitoring and sampling equipment which comprises a sensing device, a sampling device, a communication device and a control unit, wherein the sensing device is used for sensing the concentration of volatile organic compounds in ambient air and outputting a concentration signal; the sampling device is used for collecting gas in the environment; the communication device is used for receiving or transmitting messages; and the control unit is electrically connected with the sensing device, the sampling device and the communication device. The volatile organic compound monitoring and sampling equipment at least comprises a first sampling mode and a second sampling mode for sampling gases in the environment; in the first sampling mode, the concentration signal is received by the control unit, and when the concentration signal meets a first concentration value, the control unit starts the sampling device so as to collect the gases in the environment; and in the second sampling mode, when the control unit receives a sampling message by virtue of the communication device, the control unit starts the sampling device so as to collect the gases in the environment.

Description

technical field [0001] The invention relates to a sampling system, in particular to a sampling device for monitoring volatile organic compounds. Background technique [0002] The common volatile organic compounds (Volatile Organic Compounds, VOCs) can be further divided into eight categories according to their chemical structures: alkanes, aromatics, alkenes, halocarbons, esters, aldehydes, ketones and others . The main sources of VOCs are fuel combustion exhaust gas, industrial exhaust gas from transportation, vehicle exhaust, photochemical pollution, petroleum products, chemical solvents, etc. It is colorless and almost odorless in light concentrations, and has a similar odor to petroleum in high concentrations, and its composition can only be determined after testing. [0003] The Environmental Protection Agency of the Executive Yuan of Taiwan stipulates that the total volatile organic compound (TVOC) content is less than 0.56ppm. This ppm-level standard is quite small...

Problems solved by technology

The time required to get the report from collection to inspection is difficult to control and complete in a short time, and the efficiency is very low, making the victims wait for the test results all day long

[0005] Even under the emission standards set by the Environmental Protection Agency, the declaration of air pollutants and the implementation of related penalties, there are still unscrupulous operators who discharge untreated air pollutants through pipelines at night in order to evade their own environmental protection responsibilities , causing nearby residents to smell bursts of peculiar smell and make a complaint to the service command center. When the inspectors get the report, they must rush to the scene to take samples. The efficiency is low and it is difficult to collect the leaked VOCs immediately and accurately.
