Abstract

The invention relates to a device to inspect the sand gasoloid concentration and the variational rule. The real-time inspector is made up of the sampling system, the gas-liquid transition ware, the forced ventilating system, the data collecting, storage and the wireless transfer system and the computer. The data collecting, storage and the wireless transfer system is made up of the data acquisition device, the data control instrument and the wireless transfer module; the sampling system, the gas-liquid transition ware, the forced ventilating system, the data acquisition device are all connected with the data control instrument which is connected to the wireless transfer module by the signal line which is connected with the computer by the data communication wet. The invention is used in the closed earth surface, so it can sample in many points, layers and gradients. The invention is proper for the country condition and has the proper price and reliable performance.

Description

technical field [0001] The invention relates to an instrument for real-time monitoring of sandstorm and dust aerosol concentration and its changing rule, in particular to a sandstorm and sanddust aerosol concentration real-time monitor. Background technique [0002] Sandstorm is one of the main environmental problems that people care about. The windy weather when the sandstorm occurs seriously erodes the soil and aggravates the process of land desertification. At the same time, it transports a large amount of sand and dust to the downstream area, which makes the land desertification and air environment deterioration in the downstream area, and causes damage to human health and social economy. In recent years, domestic and foreign scholars have done a lot of research work on sandstorms. However, the sand emission, transmission, and dust fall of sandstorms are very complicated processes, and our understanding of this is very limited due to various factors. We still can't fu...
