Description
Technical Field
The utility model belongs to an environmental monitoring system for observe the sampling of atmospheric pollution.
Background
The dustfall refers to the particulate matter naturally settled in a dust collecting cylinder (made of glass or plastic) by gravity under the air environment condition, and the measurement unit is the ton of the particulate matter settled in each square kilometer area per month. The dustfall is a reference index of atmospheric pollution, the range and the pollution degree of the atmospheric pollution can be observed according to the measurement result, and people usually judge the cleanliness of the atmosphere by using the dustfall amount. The periphery of the dust falling sampling point is wide in environment, the circulation of air cannot be influenced, high buildings, trees with adsorption capacity and local pollution sources are avoided, the influence of the external environment on sampling point atmospheric sampling is eliminated, and the sampling accuracy is guaranteed. Meanwhile, the consistent external conditions are set for various sample points as much as possible, so that the obtained data information can have the referential property and the comparability, the data can be conveniently sorted and analyzed, and the change rule in the data information can be explored; in order to prevent interference from dust during measurement, the dust collecting cylinder should be 5-12 m away from the ground.
The dust fall monitoring generally adopts a grid point arrangement method, and a method for carrying out grid division on monitoring sampling points in a coordinate mode on a monitored area and carrying out uniform arrangement on the sampling points. The method is suitable for distribution in areas with more pollution sources. The method eliminates the influence of human factors, is set in an intuitive space distribution mode, is less restricted by conditions and has strong randomness.
At present, most dust collecting barrels in dust fall monitoring are placed on the roof of a building, and the dust collecting barrels are inconvenient to place, firstly, because the position of the building is fixed, a dust collecting cylinder cannot be placed according to the calculation place of a grid point distribution method strictly, and environment monitoring personnel need to climb up when replacing the dust collecting cylinder, if more dust fall collecting points exist, the outdoor workload is very high, and danger is easy to occur; secondly, due to different heights of different buildings, the placing heights of the dust collecting cylinders of the sampling points cannot be kept at the same height, and the accuracy of dust collection is influenced; and thirdly, the dust suppression device is placed on the top of a building and is difficult to be influenced by platform dust, so that the influence of a local environment on the dust suppression of a sampling point is caused. Fourth, the conventional cylinder holder is deteriorated in stability and firmness as the use time is prolonged, so that it is easy to cause safety or monitoring accidents in bad weather.
