Abstract

This invention concerns gas-liquid separation device and its method to separate micro-droplet from gas. Assemble one gas inlet pipe in one end wall of sealed container with nozzle; fix multihole retention felt pad on bottom wall of container before the nozzle front 0.5~10mm; there is micropore filter membrane pressed and sealed by edge in container; set gas outlet on top wall of container; set liquid outlet with one-way valve for intercepting liquid on downside wall of container front of pad; use two-class separation way with first class high speed spray absorption and interception and second class filter. The invention overcomes shortcomings of low efficiency and short life, and ensures the treated gas to satisfy require.

Description

technical field [0001] The technical solution of the present invention relates to a combined device for separating particles from gas, in particular to a gas-liquid separation device and its separation method for separating micro-droplets from gas. Background technique [0002] In many occasions, it is necessary to separate the gas from the tiny liquid droplets it carries, so as to achieve the purpose of separating and removing the liquid from the gas. For example, oxygen is produced by electrochemical or electrolytic methods. When the oxygen produced by the anode is separated from the electrolyte, it carries a large number of electrolyte micro-droplets. When oxygen is used for human respiration, the electrolyte micro-droplets with strong alkalinity or acidity must be eliminated. CN 1051401 mentions that when hydrogen and oxygen are produced by electrolysis, a corresponding gas-liquid separation device must be provided, but no specific technical method is proposed. [0003...
