[0025] Example

[0026] The method for rapid sampling of atmospheric dust reduction according to the present invention involves devices including a dust collecting cylinder, a fixed basket, a pipe clamp, a support rod, a fixed pile, a prefabricated base, a fixed ring, a pull wire, a pull wire fixture, a handle, It is composed of loading and unloading rod, hook, sample collection bag, fixed ring or rope and glass beads. Dig a hole on the ground of the observation point, put the prefabricated base 6 vertically into the pit, and fill the soil firmly. The prefabricated base 6 is an integral cement prefabricated block or top surface The open box body, the bottom is made of metal, the four walls are prefabricated cement boards or wooden boards, and the fixed pile 5 is welded to the metal bottom surface. The box body can be filled with excavated soil or stones on the prefabricated base 6. Three cable fixtures 10 are tied to the surrounding ground, and the horizontal angle between th...

Abstract

The invention provides a quick airborne dust sampling method, which requires a dust collecting cylinder, a fixing basket, a pipe collar, a support rod, a fixing pile, a prefabricated base, a fixing ring, stay wires, stay wire fixing articles, a handle, an assembling and disassembling rod, a hook, a sample collecting bag, a fixing ring or a rope and glass balls. By the aid of the method, a user can conveniently assemble and disassemble the dust collecting cylinder without climbing, dust samples in the dust collecting cylinder can be directly collected and loaded into the bag, a sample acquisition speed is increased, the weight of articles carried for acquiring the samples is reduced, and the dust collecting cylinder does not need to be changed. The method has the advantages that a dust collecting cylinder mounting support can be simplified, the dust collecting cylinder is assembled and disassembled more conveniently, and outdoor workload can be effectively reduced, and the method is wide in applicable area, not only can be used in arid areas, but also can be used in humid areas, and can be widely applied to research of environments, ecology, aeolian landform, sand control engineering and the like.

Description

technical field [0001] The invention relates to a fast sampling method for atmospheric dust in the monitoring of atmospheric environment quality. Background technique [0002] Dustfall refers to atmospheric solid particles with an aerodynamic equivalent diameter greater than 10 microns that can be naturally settled, and it is one of the main indicators for atmospheric environment monitoring. At present, the general method of collecting dust is the natural collection method of the container, and the dust collection cylinder is a general instrument for dust collection. The concentration of sand and dust near the surface decreases with the increase of height, so the dust collection cylinders are erected at different heights, and the amount of dust collected is also different. According to the national dust observation standard (GB / T 15265-94), the installation height of the dust collection cylinder should be 5-12m above the ground. Regular replacement of the dust collecting c...
