Passive gas separator and accumulator device
A separation device employing a gas separation filter and swirler vanes for separating gas from a gas-liquid mixture is provided. The cylindrical filter uses the principle that surface tension in the filter pores prevents gas bubbles from passing through; the gas collects in the interior of the filter to form larger bubbles in the center of the device. The device is suited for microgravity since the swirlers induce a centrifugal force which forces liquid from the inner region through the pores and the device outlet while the entrained gas is trapped by the filter. The device includes a cylindrical gas storage screen enclosed by the filter. The screen has pores larger than those of the filters. The screen prevents larger bubbles that have been formed from reaching and interfering with the pores of the filter. The device is initially filled with a gas other than that which is to be separated; this results in separation of the gas even before gas bubbles are present in the mixture. Initially filling the device with the dissimilar gas and preventing the gas from escaping before operation can be accomplished by sealing the dissimilar gas in the inner region with a ruptured disc which can be ruptured when the device is activated for use.
