Abstract

PURPOSE:To improve reliability of an apparatus and to enable reutilization of the apparatus by inserting an end of a discharge pipe to a main body of a tank and by providing a vessel attached to surround the discharge pipe and plural numbers of screen to the inside of the vessel. CONSTITUTION:Propellant in the main body 1 of a tank is transported to a chamber 6 by the pressurized gas fed to the main body 1 of the tank through a wire gauze 8a and a tunnel mesh 8, and is discharged through the screen to the discharge pipe 2 from a discharge port 9. Bubbles contained in the propellant introduced into the tunnel mesh 8 from the main body 1 of the tank are trapped by the wire gauze 8a. Bubbles passed through the tunnel mesh 8 are trapped by the plural numbers of screen, gather to the center of the vessel 4, and gas is collected to the external peripheral side of the vessel 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas-liquid separator that is capable of discharging only a normal liquid from an outlet of a tank.

In space, where there is no gravity, the acceleration always fluctuates in the range of a minute J to several 2, so the liquid in the replenishment tank becomes unstable.
It is difficult to fix the liquid level. Therefore, since gas is mixed into the liquid in the tank, a gas-liquid separator is required to always take out only the liquid from the outlet of the replenishment tank.The example of such a conventional gas-liquid separator is As shown in FIGS.

In Figure 1, (a) is the tank body, (b) is the tank body (a
), (C) is the outlet for the supplement (d), (e) is the pressurized gas for compressing the diaphragm (b), and the diaphragm (h) is the pressurized gas (e )
The supplementary medicine (d) is compressed and discharged from the discharge port (C). However, with such conventional devices, it is difficult to increase the size, the diaphragm (5) lacks reliability, and cannot be reused.
There were drawbacks such as.

Further, V) in FIG. 2 is a rubber bladder, and the same reference numerals as those shown in FIG. 1 in the figure indicate the same ones. In this device, the supplement (d) trapped in the bladder V) is compressed by pressurized gas (-) and is discharged from the discharge port (C). However, in this conventional device, since the bladder V) is made of rubber, it cannot be used depending on the type of supplementary medicine, it cannot be made larger, and the rubber lacks reliability, making it impossible to reuse. There was a drawback.

The present invention was made for the purpose of providing a gas-liquid separation device that is large-scale, highly reliable, and reusable.
A discharge pipe with one end inserted into the tank body, a container installed inside the tank body so as to surround the discharge pipe, a plurality of screens installed radially inside the container, and a liquid delivered into the container. Embodiments of the present invention will be described below with reference to the drawings.

Connect the discharge pipe (2) to the required position in the spherical tank body (1), insert one end of the discharge pipe (2) into the tank body (11), and insert the lid into the tank body (1). A cylindrical container (4) to which a plate (3) is fixed is installed approximately concentrically with the discharge pipe (2), and a partition plate (5) is fixed radially to the container (4) so as to be placed inside the container (4). forming a plurality of chambers (6);
λ A plurality of all-mesh screens (7) in each chamber (6)
α) (7Z')G'7c) are arranged radially to form small chambers C6(1)C6b)C6c)C6d), and an outlet (9) is bored in the extraction pipe (2). Each small chamber (6d) is connected to the discharge pipe (2), and each small chamber (fia) is connected to a side of the tank body (1), which has a channel-shaped steel cross section and faces toward the center, as shown in Fig. 5. Wire mesh (8a
) is connected to the tunnel mesh (8), and the tunnel mesh (8) is arranged along the inner surface of the tank body (1).

The wire mesh of the screen is about 400 to 2300 mesh, because if the 400 mesh is large, the effect of forming surface tension will be reduced, and if the mesh is smaller than 2300 mesh, the pressure loss will be large. In addition, the wire mesh for the tunnel mesh should be approximately 500 mesh in consideration of pressure loss and bubble removal.

Supplementary chemicals such as LH) and LO2 in the tank body (1) are transferred to the wire mesh (8) by pressurized gas supplied to the tank body (1).
α) into the tunnel mesh (8), through the tunnel mesh (8) and into the chamber (61),
Pass through the screen (7a) (υ) C7C) and exit the outlet (9
) is discharged to the discharge pipe (2).

Air bubbles mixed in the supplement introduced from the tank body (1) to the tunnel mesh (8) are trapped by the wire mesh (8a). In addition, air bubbles mixed in the supplementary medicine that passed through the tunnel mesh (8) were trapped by the air bubble (7a) and accumulated in the small chamber (6α), and then passed through the screen (7a). Air bubbles are trapped by the screen (7b) and accumulated in the small chamber (6h), and air bubbles that have passed through the screen (7h) are trapped by the screen (7C) and accumulated in the small chamber (6C). Container (4) Since the flow path is radial, the liquid always gathers at the center of the container (4), and as shown in Figure 4, the bubbles B move toward the center of the container (4).
It gathers on the outer periphery side.

In addition, in the embodiment of the present invention, a case where three stages of screens are provided has been described, but the gist of the present invention is that it can be implemented even if multiple stages are provided, that it can be used not only in space but also as a tank on the ground, and other points. Of course, various changes may be made within the scope.

According to the gas-liquid separator of the present invention, gas-free liquid discharge can be performed even under conditions where the acceleration is from 0.1 to several J. Moreover, the tank body can be made larger, and compared to conventional methods, Since there are no rubber or moving parts, the device can have various excellent effects, such as improved durability and reliability, and is also economical because it can be reused.
