Abstract

The invention discloses a water-gas interface room temperature gas PVC (polyvinyl chloride) sampling box, and relates to a sampling device of gas samples in the field of environmental science, aiming to solve the problems that an existing water-gas interface greenhouse gas sampling device cannot meet the gas sampling requirement by different water depths and guarantee the stability of the sampling box, and cannot meet the requirement for monitoring the water-gas interface greenhouse gases. The water-gas interface room temperature gas PVC sampling box disclosed by the invention comprises a box body, a temperature preservation layer, a temperature sensor, a gas sampling pipe, a three-way valve, a battery, a lead, a fan and a floating device. The water-gas interface room temperature gas PVC sampling box can adjust the floating device up and down according to the water depths and the wind power, can change the depth of the sampling box in a water body so as to be adaptive to different water depth requirements, and guarantee the stability in high wind power, and can be used for collecting water-gas interface greenhouse gases.

Description

technical field [0001] The invention relates to a sampling device for gas samples in the field of environmental science. Background technique [0002] CH 4 , CO 2 and N 2 The global warming problem represented by the increase of O concentration is one of the major environmental problems concerned by the whole world. According to the IPCC data in 2007, atmospheric CO 2 Concentrations have increased from about 280ppm pre-industrial to 379ppm in 2005, CH 4 and N 2 The concentration of O is about 1774ppb and 319ppb, which are about twice and 18% higher than before industrialization. In the past few decades, N2O has increased linearly at a rate of about 0.8ppb per year. For this reason, the emission of greenhouse gases has become one of the issues of great concern to environmental researchers. There are many lakes and rivers in my country, and the coastline is long, with a coastline of 18,000km. There are many estuaries, islands, shallow seas, tidal wetlands and inland swamp...
