Submarine hydrothermal exhalation simulation device having observation function

Abstract

The invention discloses a submarine hydrothermal exhalation simulation device having an observation function. The device mainly comprises a vertical high pressure injection pump, a temperature control system, a pressure regulating valve, a transparent pressure vessel, a high speed camera, a water cooling system, a pressure gauge, a sulfide collecting device, a pressure release valve and a stop valve. The device can simulate submarine hydrothermal exhalation, can regulate different temperature, speed and chemical components of a hydrothermal vent according to different requirements and can observe by using the high speed camera. Submarine hydrothermal exhalation simulation observation is realized by using a unique structural design under the lab environment according to the principle of similarity based on the real submarine vent environment, and the highly complex physiochemical process that hydrothermal liquid jets to the relatively low temperature and low pressure environment from the high temperature and high pressure environment and mixes and reacts with the seawater is basically restored so that the conditions and the data which are difficult to obtain through pure theoretical analysis and value simulation can be provided for the research related to the hydrothermal process.

Description

technical field [0001] The invention relates to a submarine hydrothermal eruption simulation device, in particular to a submarine hydrothermal eruption simulation device with an observation function, which can be used for laboratory observation of submarine hydrothermal eruption from a high-temperature and high-pressure environment sprayed to a relatively low temperature process in a low pressure environment. Background technique [0002] Deep-sea hydrothermal activities are widely distributed in mid-ocean ridges and back-arc basins. Hydrothermal vents are windows for material and energy exchange between the ocean and the crust. The material flux brought about by submarine hydrothermal activities is similar to the flux produced by rivers to the ocean. , the heat flux generated is second only to the heat radiation from the sun to the earth. Deep-sea hydrothermal vents have a relatively high energy density (temperature is 300-400°C, eruption velocity is 1-2m / s), and the heat ...

Problems solved by technology

[0004] Therefore, the mixing reaction of hydrothermal fluid and seawater is a highly complex physical and chemical process. In addition to the drastic temperature change, it is also accompanied by the generation of sulfide particles. It is difficult to obtain the real process of hydrothermal fluid and seawater mixing by pure theoretical analysis and numerical simulation.
