Description

[Detailed description of the invention] Industrial application field This invention is a separator that is attached to gas piping for steam, compressed air, etc., and separates water (e.g., condensed water) and oil from the gas and removes it from the system. In particular, a swirling flow is generated in the separator casing, moisture and oil in the gas are separated by the action of centrifugal force, only the gas is allowed to pass through the outlet, and the separated water and oil droplets are allowed to flow down to form a drain valve. Regarding what is excluded from the outside of the casing.

Prior Art An example of a conventional steam/water separator using a swirling method is disclosed in Japanese Patent Application Laid-open No. 187910/1983. In this method, a cylindrical partition member whose lower part expands downward is placed under a swirling vane provided at the upper part of the casing to swirl the fluid, and the upper part is connected to the outlet through the inside of the partition member. , an inlet is opened at the upper part of the swirling vane on the outside of the partition member, and a drain valve is installed at the lower part of the casing. The fluid flowing in from the inlet is swirled by swirling vanes, shaking out water droplets in the gas to the outside and separating them as they flow downward. Gas rises inside the partition member and flows out from the outlet, and water droplets flow down along the inner circumferential wall of the casing and are removed to the outside by a drain valve.

Problems to be Solved by the Present Invention The conventional steam/water separators described above have a problem of poor steam/water separation efficiency. This is an attempt to separate air and water by swirling the fluid and using the action of centrifugal force to send water droplets with a large mass to the outside to separate air and water. This is because the gas swirls around the center and is carried to the outlet side by the gas flow without being separated.

Therefore, the technical problem of the present invention is to collect and grow the moisture and oil in the gas to a mass that can be blown outward by centrifugal force before reaching the swirling vane, and to separate the air and water by the swirling vane. It is about increasing efficiency.

Means for Solving the Problems The technical means of the present invention taken to solve the above-mentioned technical problems is to arrange a cylindrical partition member in the upper part of the separator casing, and to An annular space is formed between the annular space and the casing, a swirling vane is arranged in the annular space, the upper part of the annular space is connected to the inlet, the lower part is connected to the drain valve part, and the hole inside the partition member is connected to the outlet, A filter part is formed separately from the separator casing, a mesh is laminated on the filter part, an inlet and an outlet of the filter part are provided, and the outlet of the filter part and the inlet of the separator casing are connected by a connecting pipe. , a groove substantially parallel to the axis of the connecting tube is formed on the inner periphery of the connecting tube.

Effect The operation of the above technical means is as follows.

Moisture and oil contained in the gas are captured by the laminated mesh of the separately formed filter section before reaching the swirler blades, and collect and grow while passing through the grooves of the connecting pipe. The grown water and oil become water and oil droplets that are large enough to be blown outward by centrifugal force and are transported to the swirling blades. The transported water droplets and oil droplets are swirled by swirling blades,
It is swung outward and collides with the inner peripheral wall of the casing,
It drips downward along the inner circumferential wall of the casing, flows down to the drain valve, and is removed to the outside.

Effect of invention The present invention produces the following specific effects.

By forming the filter section separately from the separator casing, it is possible to select and replace the filter as appropriate depending on the amount of water droplets and oil contained in the gas, so the optimal filter section can be selected according to the usage conditions. It can be easily adopted and can improve the separation efficiency of air and water.

Moreover, the size can be made large enough to shake out water and oil in the gas to the outside by centrifugal force before reaching the swirl vane, and the separation of air and water by the swirl vane can be ensured.

Example An example showing a specific example of the above technical means will be described (see FIG. 1 and FIG. 2).

Fasten the upper body 1, lower body 2, and bottom cover 3 with bolts 20,
21 to form a pivotable separator casing. A filter section 27 is formed separately from the rotating separator casing. The filter portion 27 is formed by attaching the inlet cover 4 to the filter body 23 with bolts 19. The inlet lid 4 is provided with an inlet 5 of the filter section 27, and the filter section 27 and the rotating separator casing are connected through a connecting pipe 24 to form a steam/water separator.

The mesh 11 is laminated on the filter portion 27. The mesh 11 is a thin wavy mesh made of thin metal wires and graph fibers, stacked so that the waves alternate, and has an outer diameter large enough to fit into the filter body 23. A screen 22 is attached to the lower end of the mesh 11, and the mesh 1
Prevent #1 from slipping out.

As shown in FIG. 2, the cross section of the connecting tube 24 has a plurality of concave grooves on its inner periphery that are substantially parallel to the tube axis of the connecting tube 24.

Inside the upper body 1, a double substantially cylindrical partition member 7 is arranged. The outer cylinder of the partition member 7 has a straight shape and is formed lower than the inner cylinder. The inner cylinder has a shape that gently widens at the top and bottom. A swirl vane 12 is formed integrally with the partition wall member 7 in an annular space 9 between the double cylinders of the partition wall member 7. The inlet 5 of the filter section 27 communicates with the upper part of the annular space 9 via the mesh 11 and the connecting pipe 24, the lower part of the annular space 9 communicates with a drain valve chamber 13, which will be described later, and the inside of the partition member 7 communicates with the outlet 6. communicate.

The lower body 2 and the bottom cover 3 form a drain valve chamber 13 as a drain valve section. A spherical float 14 is placed in a free state within the drain valve chamber 13. A drain valve seat 15 is attached to the inner end of a drain port 16 on the bottom cover 3. A float cover 17 covering the float 14 is attached, and a connecting opening 18 is formed at the bottom. float cover 1
7 is provided with a ventilation hole 25.

Next, the action will be explained.

Moisture or oil in the fluid that enters the filter section 27 from the inlet 5 is captured by the laminated mesh 11, and is transferred from the outlet side of the filter section 27 to the connecting pipe 24.
During this time, the air and water gather and grow until they reach the annular space 9, where they are swirled by the swirling blades 12 to separate the air and water. The separated water droplets and oil flow down along the inner peripheral wall of the casing and reach the drain valve chamber 13. Water droplets and oil accumulated at the bottom of the drain valve chamber 13 are removed by the float 1.
4 floats up and leaves the drain valve seat 15, and is removed from the system through the drain port 16. By connecting the filter part 27 and the separator casing with the connecting pipe 24 provided with a groove, the filter part 2
Since the water droplets and oil captured in the swirler 7 gather and grow while reaching the swirler 12, air and water can be separated more reliably in the swirler 12.
