Problems solved by technology

Due to the very slow sedimentation rate of deep-sea sediments, it takes a lot of manpower and material resources to obtain enough samples for experimental analysis
Moreover, the distribution of particulate matter in different regions of the ocean is not uniform, so the actual sedimentation flux in a certain region cannot be obtained by this method
In addition, there will be unnatural sedimentation substances in the sample captured in this way, which will affect the purity of the final sample

Abstract

The invention relates to a deep sea turbidity current solid-liquid two-phase separation device. Comprising a turbidity current separation cavity, a turbidity current inlet part arranged at the side edge of the turbidity current separation cavity, a flow guide separation assembly arranged in the turbidity current separation cavity, a seawater outlet part arranged at the top of the turbidity current separation cavity, and a sedimentation funnel arranged at the bottom of the turbidity current separation cavity, wherein the turbidity current inlet part is used for guiding deep sea turbidity current to flow into the turbidity current separation cavity according to a specified path; the flow guide separation assembly is used for changing the flowing direction of the deep sea turbidity current introduced from the turbidity current inlet part, so that particulate matters in the deep sea turbidity current are separated from seawater; the seawater outlet part is used for discharging seawater separated by the flow guide separation assembly; the settling funnel is used for discharging particulate matters separated out by the flow guide separation assembly, and the deep sea muddy current solid-liquid two-phase separation device can realize efficient solid-liquid two-phase separation in situ in deep sea and has the advantages of simple structure, low cost and high efficiency.

Description

technical field [0001] The invention relates to the technical field of solid-liquid two-phase separation, in particular to a deep-sea turbidity current two-phase separation device. Background technique [0002] The ocean plays a very important role in regulating global climate change, which is clearly recorded in the flux and material composition of ocean sediment particles, while the carbon entering the deep sea is mainly in the form of sediment particles, plankton fecal particles Or the dead shell is aggregated and expanded by physical and chemical action, thereby forming a substance called "marine snow", which is driven by ocean currents and eventually sinks to the seabed; the traditional sampling method of particulate matter is to collect a large number of particles. Filtered from seawater. Because the sedimentation rate of deep-sea sediments is very slow, it takes a lot of manpower and material resources to obtain enough samples for experimental analysis. Moreover, th...
