Gas-liquid multistage separation device for gas bearing experiment for incoming flow of pump

Abstract

The invention discloses a gas-liquid multistage separation device for a gas bearing experiment for incoming flow of a pump. The gas-liquid multistage separation device comprises a tank as well as a first-stage separation part, a second-stage separation part and a third-stage separation part which are arranged in the tank, wherein the first-stage separation part is arranged in upper space of an inner chamber of the tank, the second-stage separation part is arranged on the peripheral surface of the inner wall of the tank and connected with the first-stage separation part through a water pipe, and the third-stage separation part is arranged at the bottom of the tank; the first-stage separation part comprises a spiral pipe, spray nozzles and baffle plates; the second-stage separation part comprises an annular chamber, inlet baffle plates, gas-liquid separation plates and an outlet baffle plate; the third-stage separation part comprises a liquid separation plate and a conical diversion pipe which is big end up. The gas-liquid multistage separation device adopts compact mechanism, is high in separation efficiency and can effectively solve the problem about fluid degassing in experiments and engineering.

Description

technical field [0001] The invention relates to the field of pump experiments and the technical fields of chemical machinery, in particular to a gas-liquid multi-stage separation device for gas-containing experiments in pump flow. In addition to meeting the separation of water-insoluble gases in water, it can also meet the separation of fluid-insoluble gases in other fluids. Background technique [0002] In enterprises or laboratories, the experimental medium used in pump test benches is generally water, and it is recycled. It is sucked into the pump by the water storage tank, and then discharged into the water storage tank at the outlet of the pump. The experimental gas filling device for the incoming flow containing gas is generally located in the inlet pipe between the pump and the storage tank. However, to ensure that the gas phase content percentage at the pump inlet is completely controlled by the gas filling device, it is necessary to ensure that the water in the wa...

AI Technical Summary

Problems solved by technology

In terms of the gas-liquid mixed fluid where the separation fluid is the main one, the commonly used separator is relatively simple.

Most of the existing gas-liquid separation devices use only gravity separation, let the fluid velocity drop first and then separate, the separation efficiency is not very ideal, and the volume is huge, which is not conducive to the laboratory with a small footprint
