Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0035] In this example, if figure 1 , as shown in 2, a rotary vane type multi-stage micro-bubble screening device provided by the present invention includes a cylindrical gas-liquid mixing chamber 1, a primary air bubble separation chamber 2, a secondary air bubble separation chamber 3, and a tertiary air bubble separation chamber 4 , single-phase liquid chamber 5, three mixing impellers, one recovery impeller, corresponding air outlet branch pipe and two pressure sensor detection holes. Among them, th...

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...
