Description

TECHNICAL FIELD The present invention relates to a separator which is attached to a gas pipe such as steam or compressed air and separates condensed water, oil, etc. in a gas with a separation plate and removes it out of the system. In particular, it relates to the production of a separation plate that enhances the separation efficiency of air and water.

2. Description of the Related Art As a conventional steam separator, for example, the one shown in FIG. 3 has been used. The separator casing 30 forms an inlet 31, a water-gas separation chamber 32, and an outlet 33, and a plurality of separation plates 34, 35, 36 are connected to the inside of the casing 30 at one end thereof in the separation chamber 32. The other end is opened and installed in the separation chamber 32, and the separated droplet passage 37 and the discharge port 38 are provided in the lower portion of the casing 30. A trap 39 for discharging only the separated droplets is connected to the discharge port 38.

The fluid containing the droplets flowing from the inlet collides with the separation plate 34, and the droplets adhere to the surface of the separation plate 34 and flow down,
The lower end of the separating plate 34 is blown off by the gas flow. Among the blown-off droplets, the one having a large mass collides against the next surface of the separating plate 35 again due to the inertial force and is dropped to pass through the passage 37 and the discharge port 38.
Further, it reaches the trap 39 and is removed from the system, and most of the small-mass liquid droplets and gas flows change the flow direction because they have a small inertial force, and do not collide with the separating plate 35 but reach the next separating plate 36 and collide with them. And drip. Thus, the water vapor is separated while repeating the collision and the change of the flow direction, and the droplet is discharged from the discharge port 38, and the gas flow separated from the droplet is discharged from the outlet 33.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above, some of the droplets are not carried out to the outlet side and high separation efficiency cannot be obtained, or the shape of the separator casing is changed to obtain higher separation efficiency. There was a problem that had to be big.

This is because, among the liquid droplets blown off from the lower ends of the separation plates 34 and 36, the liquid droplets having a small mass are again carried out by the gas flow. In order to reduce the amount to be carried out and increase the separation efficiency, it is necessary to provide a large number of separation plates so as to increase the chances of collision, and therefore the size becomes large.

A technical object of the present invention is to obtain a collision-type or inertial-force steam-water separator having a small size and high separation efficiency.

Means for Solving the Problems The technical means of the present invention taken to solve the above-mentioned problems is to form an inlet, a water vapor separation chamber and an outlet in a separator casing, and to separate a plurality of fluids in the separation chamber. In the case of separating steam and water by inertial force caused by colliding with plates or spherical members or changing the flow direction with separating plates, many spherical members are placed with some of the spherical members in contact with each other Then, the plurality of separation plates are arranged by alternately providing openings in the vertical direction of the separation chamber, and the end portion on the opening side of the separation plate on the inlet side is almost the same as the spherical member portion of the separation plate on the outlet side. It is arranged horizontally with the central part.

The fluid containing the liquid droplets flowing in from the inlet collides with a large number of spherical members on the surface of the separating plate. Upon collision, the liquid droplets adhere to the surface of the spherical member and flow down while growing along the mutual contact portions. The droplets that have grown and become large in mass are blown off by the gas flow from the lower end of the spherical member or the lower end of the separation plate. Since the blown-off droplet has a large mass, the flow direction is hardly changed by the inertial force, and the droplet collides against the surface of the next spherical member or the inner surface of the casing again and drops. The separated gas flow of droplets changes its flow direction to reach the outlet.

EFFECTS OF THE INVENTION The present invention produces the following unique effects.

The droplets in the fluid adhere to the spherical member, grow along the mutual contact portions to become droplets with a large mass, and are blown away by the gas flow and do not change their flow direction and do not reach the outlet, which is high. The separation efficiency of air and water can be exhibited.

Further, by disposing a large number of spherical members, even if the separation plate has a small cross-sectional area, the area where the fluid collides increases, and the separator can be made compact.

Example An example showing a specific example of the above technical means will be described.
(See FIGS. 1 and 2) In the separator casing 1, the inlet 2, the separation chamber 3 and the outlet 4 are formed to communicate with each other. Separation plates 5 and 6 are alternately provided in the separation chamber 3. The separating plates 5 and 6 are substantially L-shaped in cross section, and form continuous portions 7 and 8 and openings 9 and 10 which are continuous with the inner circumference of the casing 1. Separators 5,6
Grooves 25 and 26 are provided at the lower end and the upper end of the groove 2
Notches 27 and 28 are provided at both left and right ends of 5 (see FIG. 2). The openings 9 and 10 have a shape corresponding to the inner shape of the casing 1, and in the present embodiment, have a circular shape (see FIG. 2). Separation plate
Steel balls 11a, b as numerous spherical members on the inlet 2 side surface of 5,6
Are held and arranged by the wire mesh 12 for holding steel balls, with some of them in contact with each other. The ends of the wire mesh 12 are fixed to the ends of the separation plates 5 and 6 by welding or the like. A through hole 13 is provided in the continuous portion 8 below the separation plate 6, and an outlet 14 is provided at the lower end on the outlet 4 side of the casing 1 to connect an air trap or a steam trap 15 for ejecting only liquid. Reference numeral 20 is an outlet separation plate, which is a passage in which droplets accumulated in the accumulation portion 21 are formed in a circular shape along the inner circumference of the casing 1.
22 to reach the outlet 14.

The fluid containing the liquid droplets flowing in from the inlet 2 collides with a large number of steel balls 11a on the separation plate 5. The droplets adhere to the surface of the steel ball 11a and flow down while becoming large droplets along their mutual contact portions.
The lower end of the steel ball 11a and the lower end of the separating plate 5 or the notch 27, 28
The droplets are blown away by the gas flow. Since the blown-off droplet has a large mass, it moves to the outlet 4 side in a substantially horizontal shape, collides with the steel ball 11b of the next separating plate 6 and drops. Since most of the gas flow has a small inertial force, the flow direction is largely changed and reaches the outlet 4 through the opening 10. The droplets dropped on the separating plate 6 reach the discharge port 14 through the through hole 13 and are trapped.
It is discharged from the system from 15.

Since the droplets blown off by the gas flow have a large mass, they are not entrained in the gas flow again and are not carried to the outlet, and a high gas-water separation efficiency can be exhibited. In addition, since a large number of steel balls 11a and 11b are provided, the chances of fluid collision increase, and the separator casing 1 can be made compact.
