Abstract

The invention discloses an atmospheric sampling instrument, and relates to the technical field of atmospheric sampling equipment, and the atmospheric sampling instrument is characterized by comprising a sampling box and a lifting device, the sampling box comprises a box body, fixed columns are arranged on two opposite side surfaces of the box body close to the front surface and the back, the fixed columns are provided with vertical threaded grooves, and threaded lifting rods are arranged in the threaded grooves; the sampling box is connected with the lifting device through a threaded lifting rod; a detection device, a control device, a micro sucking pump, a gas flow meter, a plurality of sample storage tubes, a shunt tube I, a shunt tube II, a storage battery and a buffer tube are arranged in the box body. And atmospheric sampling at different heights can be carried out. The execution operation is simple, the sampling personnel work easily, the sampling bottle does not need to be replaced for storage, and the sampling quality is improved; and the sustainable working time of the whole sampling instrument is prolonged by the solar panel and the storage battery.

Description

technical field [0001] The present invention relates to the technical field of atmospheric sampling equipment, and more particularly, to an atmospheric sampling instrument. Background technique [0002] There are many types of atmospheric samplers. According to the collection object, it can be divided into gas (including steam) sampler and particle sampler; according to the place of use, it can be divided into environmental sampler, indoor sampler (such as the sampler used in the factory workshop) and pollution source sampler (such as chimney) sampler). In addition, there are special-purpose atmospheric samplers, such as a sampler that simultaneously collects gas and particulate matter, which can collect sulfur dioxide and particulate matter, or hydrogen fluoride and particulate matter in the atmosphere, which is convenient for studying the relationship between sulfur or fluorine in gaseous and solid substances. There are also samplers that collect bacteria in the air. In...
