Underwater bubble manufacturing device and method

Abstract

The invention discloses an underwater bubble manufacturing device and method. The device comprises a direct-current water pump, a reducing straight-through joint, a transparent hose, a T-shaped pipe, a sample injection pad, a sample injector, a nylon rope and a fixed bracket. A water outlet of the direct-current water pump is connected with the reducing straight-through connector, the reducing straight-through connector is connected with one end opening in the horizontal direction of the T-shaped pipe through the transparent hose, and the other end opening in the horizontal direction of the T-shaped pipe extends into water through the transparent hose; a connector in the vertical direction of the T-shaped pipe is blocked by a sample introduction pad; the sample injector is used for extracting a gas sample and injecting gas into the T-shaped pipe to form bubbles; and the nylon rope is used for hanging the fixing support, and the fixing support is hung in water through the nylon rope. The device and method can control the volume of the generated bubbles and the release depth of the bubbles, detect the volume, components and the like of the collected gas, and can explore the gas exchange process of the bubbles in the water body rising process and the water body.

Description

technical field [0001] The invention belongs to the technical field of ecological environment and relates to water environment, in particular to an underwater air bubble manufacturing device and method. Background technique [0002] "Bubbling" is a common phenomenon in natural water bodies. The principle is that the organic matter and nutrient salts accumulated in the sediments of the water body, under the action of microorganisms, produce gases through a series of biochemical processes, and these gases are continuously accumulated in the sediments. When certain conditions are met, it emerges from the sediment into the water body in the form of air bubbles. The gas composition in the bubbles contains methane (CH 4 ), nitrous oxide (N 2 O) and nitrogen (N 2 ) etc., where CH 4 and N 2 O as a greenhouse gas is a research hotspot of scholars from all over the world; N in bubbles 2 The existence of bubbles reflects the denitrification process inside the water body, which re...

Problems solved by technology

However, due to the lack of effective direct observation methods in the special underwater environment and the fact that the bubble itself is greatly affected by the water pressure, it has become a difficult problem to artificially generate a single bubble with a known volume underwater.
