High-altitude haze detecting device

Abstract

The invention relates to a high-altitude haze detecting device. According to the high-altitude haze detecting device, by combining a high altitude balloon with a pod, high-altitude haze detection is carried out; by using an electromagnetic pressure reducing exhaust valve I and a helium tank in the pod, the high altitude balloon is lifted; by using an antenna at the rear part of the pod and an electric steering engine and a propeller which are at the bottom of the pod, the device can be remotely controlled to control the advancing directions of the high altitude balloon in different wind layers, and the power of the high altitude balloon is provided by a storage battery pack in the pod; by using a measuring and compensating device in the pod, a high-altitude haze sample is collected to be detected; on the basis of a beta-ray and dynamic heating system method, a refrigerator and a weighing device are additionally arranged to carry out secondary weighing on condensed volatile substances so as to further improve the measuring accuracy; in order to increase the detection frequency, a paster storage device is used to store a paster and automatically change the paster; and as the pod cannot keep horizontal to affect a weighing result under an effect of wind power in the air; and by using a balancing device, the measuring and compensating device is kept in balance.

Description

technical field [0001] The invention belongs to the field of environmental protection and relates to a high-altitude haze detection device. Background technique [0002] Haze is a combination of fog and haze. Smog is common in cities. In many areas of China, fog is combined with haze as a disastrous weather phenomenon for early warning and forecasting, collectively referred to as "smog weather". Haze weather is a state of air pollution. Haze is a general expression of the excessive content of various suspended particulate matter in the atmosphere, especially PM2.5 (particulate matter with an aerodynamic equivalent diameter less than or equal to 2.5 microns) is considered to cause haze. The "culprit" of the weather. Smog detection refers to the use of detection devices or equipment to detect the current local PM2.5 particle content, and the detected data will give early warning to people's activities to avoid harm to the human body. The existing detection methods mainly i...

However, in addition to moisture, there are also volatile substances in the tested sample. When the dynamic heating system raises the temperature to remove moisture, the volatile substances will also pass through the filter paper, which cannot be detected by the β-ray method, resulting in detection errors. There is a need for a high-altitude haze detection device that can perform long-term detection at high altitudes, is flexible to operate, and can compensate for measurement accuracy
