Environmental real-time monitoring and gas sampling method

Abstract

The invention relates to an environmental real-time monitoring and gas sampling method. The method comprises the following steps of: monitoring the air in the ambient environment in real time by adopting an environmental real-time monitoring and gas sampling device, and sampling the air windward by adopting an air bag when the measured concentration of a harmful gas is higher than a set value; and then conveying the air bag to a monitoring center for detection and reference. According to the wind direction measured by an embedded server, the geographical position of the environmental real-time monitoring and gas sampling device and the known geographical position of a chemical enterprise, the source of the harmful gas is judged. The embedded server also calculates the time that the harmful gas reaches the downstream residential area according to the wind direction and the wind velocity; and then corresponding alarm information is sent to the monitoring center and / or an alarm center ofthe downstream residential area through a wireless communication module to inform the downstream residents of evacuating. Meanwhile, related emergency centers implement rescue measures according to the category of the leaked gas.

Description

technical field [0001] The invention relates to the technical field of real-time monitoring of the environment, in particular to a real-time monitoring of the environment and a gas sampling method. Background technique [0002] The characteristic pollutants (exhaust gas) emitted by industrial enterprises, especially chemical enterprises, have the characteristics of transient, occasional and sudden, which not only affect the air quality in some areas, but also cause disturbance incidents. When environmental monitoring personnel rush to the scene after receiving complaints from residents, they often fail to capture the instantaneous maximum concentration of pollutant discharge, resulting in the lack of sufficient basis for the environmental management department to manage the enterprise. This not only increases the workload of environmental monitoring personnel, but also It also increases the difficulty of environmental management. At present, my country does not have an unin...

Problems solved by technology

When environmental monitoring personnel rush to the scene after receiving complaints from residents, they often fail to capture the instantaneous maximum concentration of pollutant discharge, resulting in the lack of sufficient basis for the environmental management department to manage the enterprise. This not only increases the workload of environmental monitoring personnel, but also It also increases the difficulty of environmental management

At present, my country does not have an uninterrupted continuous monitoring instrument for the unorganized emission of waste gas at the factory boundary of industrial enterprises in China.
