A rotary vane type multi-stage micro-bubble screening device

Abstract

The invention provides a rotary vane type multistage microbubble screening device. The device comprises a cylindrical gas-liquid blending cavity, a first-stage bubble separating cavity, a second-stagebubble separating cavity, a third-stage bubble separating cavity and a single-phase liquid cavity which are formed in sequence in the fluid flowing direction. A roiling impeller is arranged between the cylindrical gas-liquid blending cavity and the first-stage bubble separating cavity as well as between the first-stage bubble separating cavity and the second-stage separating cavity and between the second-stage bubble separating cavity and the third-stage bubble separating cavity. A restoring impeller is arranged between the third-stage bubble separating cavity and the single-phase liquid cavity. Axial air outlet mesopores are formed in the roiling impellers and the restoring impeller correspondingly. An air outlet is formed in each axial air outlet mesopore and is connected with a corresponding air outlet branch pipe. The cylindrical gas-liquid blending cavity and the single-phase liquid cavity are provided with pressure sensor detecting holes for a fluid inlet and a fluid outlet. Thepressure sensor detecting holes are used for measuring pressure of the fluid inlet and pressure of the fluid outlet of the microbubble screening device. The rotary vane type multistage microbubble screening device has both the economical efficiency and high efficiency, and online degassing requirements of a molten salt reactor can be met.

Description

technical field [0001] The invention relates to the technical field of multistage gas-liquid separation, in particular to a rotary vane type multistage microbubble screening device. Background technique [0002] The thorium-based molten salt reactor has become one of the six candidate reactor types for the fourth-generation reactor nuclear energy system due to its advantages such as good safety, long-term supply of nuclear fuel, minimization of nuclear waste, high production capacity, and physical nuclear proliferation resistance. The energy generated by thorium fuel of the same quality is 200-250 times that of uranium fuel, and the reserves of thorium resources in the earth's crust are three times that of uranium resources. Especially in China, thorium resources rank second in the world, and its reserves are about It is 6 times that of uranium resources, and thorium-based molten salt reactors have broad development prospects in my country. [0003] Molten salt reactors will...

Problems solved by technology

However, the existing separation technology cannot perform multi-stage separation of bubbles of different sizes, and cannot obtain the separation efficiency of different sizes of bubbles and the best bubble size or bubble size distribution for separating fission gases. Therefore, it is necessary to invent a method that is both economical and Efficient multi-stage microbubble screening device
