A reaction device and method involving methane-water-gas exchange

Abstract

The invention discloses a reaction device and method involving methane water-vapor exchange. The device comprises a constant temperature device, a bubbling device, a reactor and a measuring device, wherein the constant temperature device comprises a thermostat, a water inlet device and a water outlet device; the bubbling device consists of an air blower, an exhaust plate and a fan; air holes are uniformly formed in the exhaust plate, so that a water sample in the reaction container is fully exchanged with air; the reactor refers to a hollow cylinder with a cover; small holes are formed in the rubber cover and the side walls; the whole reactor is arranged in the constant temperature device in a sleeving manner; the water sample enters the reactor from a water inlet pipe; the measuring device consists of a greenhouse gas analyzer, an air inlet pipe and an air outlet pipe; gas in the reaction container is delivered to the greenhouse gas analyzer to be analyzed by virtue of the air inlet pipe and enters the reactor by virtue of the air outlet pipe after the analysis is finished, so that the environment conditions in the reactor are constant. The device disclosed by the invention is reliable in performance, simple in structure, convenient to manufacture, difficult to damage, low in cost and simple and convenient to operate in field.

Description

technical field [0001] The invention relates to a reaction device and method related to methane-water-gas exchange. Background technique [0002] In recent years, the greenhouse effect has attracted widespread attention in the world, and more and more researches on greenhouse gases have been conducted. Methane is one of the greenhouse gases. Although its content is far less than that of carbon dioxide, its contribution to the greenhouse effect is more than 20 times that of carbon dioxide. Therefore, measuring the partial pressure of methane in water is of great significance for accurately assessing the flux and process of greenhouse gases in aquatic ecosystems, and taking corresponding measures to reduce the release of greenhouse gases in aquatic ecosystems. At present, there is no reaction device for rapid methane-water-air exchange at home and abroad.
