Embodiment Construction

[0031] Such as figure 1 , 2 As shown, the greenhouse gas collection system of the present invention, which is mainly used to collect greenhouse gases emitted by rivers, includes a water gas collection device 1 and a gas storage device 2.

[0032] The water gas collection device 1 includes a gas collection box 11, a gas collecting fan 12, a gas collection pipe 13, a first suction gas syringe 14, a battery box 15, a handle 16 and a foam board 17.

[0033] The gas collection box 11 is a rectangular box structure made of PVC material, and its outer wall is covered with aluminized film. The aluminized film can effectively function as heat preservation and heat insulation to ensure the integration of gas in the box and the gas collecting box. The internal temperature is stable; the top four corners of the gas box 11 are symmetrically installed with fixing buckles 112, and the fixing buckle 112 is also connected with a fixing rope 113. One end of the fixing rope 113 is connected with the f...

Abstract

The invention relates to a greenhouse gas collection system and a greenhouse gas emission analysis method. A collection device comprises an overwater gas collection device and a gas storage device connected with the overwater gas collection device. The overwater gas collection device comprises a gas collection tank, a gas collection fan, a gas collection pipe, a battery box, a handle and a foaming plate. The gas storage device comprises a gas collection bag and a three-way valve. By utilizing the greenhouse gas device, gas samples are collected at the nearshore positions of the two shore sides of a river and water-gas interfaces of a channel, a fish pond, a reservoir and the like, the collected samples are taken back to a laboratory, and the concentration of greenhouse gases of CO2, CH4 and N2O3 in the gas samples is measured. The collection device is simple and reasonable in structural design, low in cost and easy and convenient to operate and use, has the good stability and sealing performance. The analysis method is simple in operation steps, convenient to implement, small in experiment error, high in accuracy, and capable of effectively solving the problem that river greenhouse gases are difficult to collect.

Description

Technical field [0001] The invention relates to the technical field of environmental protection, in particular to a greenhouse gas collection system and a method for analyzing greenhouse gas emissions. Background technique [0002] In recent years, with the continuous development of the industrial economy, mankind is facing major ecological system destruction problems, and climate heretical changes are obvious, which not only include severe droughts and floods, extreme weather (extreme heat and cold), but also global Sea level rises and glaciers melt within the area. The continuous increase of atmospheric greenhouse gases is the decisive factor leading to the above problems. Greenhouse gases are some gases that absorb solar radiation reflected from the ground and re-emit radiation, such as water vapor, carbon dioxide, most refrigerants, etc., to make the earth's surface warmer, similar to the role of greenhouses in intercepting solar radiation and heating the air in the greenhou...
