Abstract
The invention discloses a geogas nano-particle separation and trapping device and a trapping method. The geogas nano-particle separation and trapping device comprises a large-diameter geogas nano-particle collector, an electric regulating valve, a nano-particle filter trap, a silicone tube, a vacuum air pump, a controller, an air blower and a spiral hollow drill; and the spiral hollow drill comprises a first spiral hollow drill, a second spiral hollow drill and a third spiral hollow drill. The geogas nano-particle separation and trapping method comprises the following steps of step S1, after equipment is connected and buried well, turning on a controller power supply, and enabling the vacuum air pump and the air blower to start to work; and step S2, enabling an A pipe of the electric regulating valve to be connected with a C pipe, and discharging waste gases inside the large-diameter geogas nano-particle collector for 30 seconds. The geogas nano-particle separation and trapping deviceand the trapping method provided by the invention solve the problems of contamination by atmospheric particulates during the sampling process and frequent trapping of large-particle-size particles.
Description
technical field [0001] The invention relates to the field of nanometer geochemistry, in particular to a device for separating and trapping geogas nanoparticles. Background technique [0002] One of the tasks of nanogeochemistry is to study the distribution, distribution, combination characteristics, and migration rules of metal nanoparticles in the earth, and use physical and chemical methods to enrich and extract nanoparticles and analyze element content to reflect and detect deep metal deposits. A large number of studies have shown that the nano-metal particles in the surface gas are closely related to the deep metal minerals. Therefore, the research on geogas nano-geochemistry has theoretical research significance and practical application value for mineral exploration. How to effectively separate nanoparticles from the geo-atmospheric medium and capture them on the carrier grid for electron microscope observation is the prerequisite and technical difficulty for nano-geo...
