Problems solved by technology

[0004] Since the gas-liquid separator for traditional water-activated batteries only considers a single flow rate in the design, when the system flow rate changes, it will have a great impact on the separation efficiency of the gas-liquid separator
If the separation efficiency drops significantly, the electrolyte containing bubbles will enter the pump or the electrolyte will be discharged out of the cabin along with the hydrogen, which will have a negative impact on battery performance
In the applied patent No. CN201521104670 and the patent No. CN201711201534, the structure of the gas-liquid separator has been improved so that it can reduce the pressure loss or achieve reversing, but its structure has a small adaptability to the flow range. The shortcomings of unstable internal air cavity and low separation efficiency require adjustment of the parameters of each component of the gas-liquid separator for optimization

Abstract

The invention relates to a multi-working-condition design method of a gas-liquid separator for a water-activated battery. The method comprises the steps of determining the main geometric parameters ofthe gas-liquid separator through a corresponding calculation method, wherein the main geometric parameters comprise a liquid inlet diameter D1; the gas outlet diameter D2, the separator base circle diameter D3, the separator barrel length L1 and the like, and meanwhile, matching the installation depth of the flow guide disc and the barrel to adopt a small taper angle form, so that the stability of a gas cavity of the gas-liquid separator can be effectively improved, and the gas-liquid separation is more thorough. The prepared enterprise separator has the good gas-liquid separation performance, the energy loss in the separator can be effectively reduced through experimental verification, the pressure drop is small, and high separation efficiency is achieved under different flow working conditions.

Description

technical field [0001] The invention belongs to the field of gas-liquid separators, in particular to a multi-working-condition design method for a gas-liquid separator for a water-activated battery. Background technique [0002] Hydrogen evolution side reactions often occur in water-activated batteries during discharge. For flow-controlled water-activated batteries, the internal electrolyte circulation is mainly driven by centrifugal pumps after being activated by water ingress. If the electrolyte is not subjected to gas-liquid separation , A large amount of hydrogen gas accumulates in the battery compartment, which will reduce the battery's load capacity, cause battery failure, and even induce battery explosion. Therefore, a gas-liquid separator is required to discharge the generated hydrogen gas out of the battery compartment. [0003] Because water-activated batteries have the advantages of long storage life, high specific energy, and high specific power, they have been u...
