Description

Separator with reflective surface

Technical field

The invention relates to a separator, i.e. a device for separating solid impurities and liquids from gases and vapors flowing through a pipe, in particular for separating solid impurities and water from steam before it enters the steam turbine.

BACKGROUND OF THE INVENTION

Until now, the T-shaped separators of Figure 1 have been used to separate the impurities and water from the steam. The steam with the impurities and water entered horizontally through the inlet throat, the steam itself turned vertically up into the outlet throat toward the turbine, on the blind end cap lying opposite the inlet throat and fall into the sludge.

This arrangement had the disadvantage of:

The impurities and water did not immediately fall into the sludge, but bounced back from the dead end cap under the outlet throat, lost speed and were pumped into the outlet throat by steaming and damaged the turbine valves and turbine blades.

If the separator did not have a sieve inserted, water and all impurities were entrained to the turbine, if the sieve was inserted in the separator, water and impurities smaller than holes in the sieve were entrained to the turbine, but they also damaged the turbine blades and reduced performance and turbine efficiency, although they did not cause an immediate crash.

The essence of the technical solution

This deficiency is eliminated by a reflector with a reflective surface in which a parabolic reflective surface is positioned in the interior of the body, between the outlet neck and the dead end cap, so that its focus lies at the point of the inlet opening of the sludge. Dirt and water flying from the inlet throat to the blind end are reflected in the focal point of the dish and thus into the sludge. Water flows through the drainage flange on the side of the sludge, solid impurities are collected at the bottom of the sludge where they can be removed during the outage. This prevents damage to the turbine and turbine valves.

BRIEF DESCRIPTION OF THE DRAWINGS

1 is a vertical section through an old type of separator without a curved reflective surface.

Fig. 2 is a vertical section through a separator with a reflecting surface in the shape of a parabolic cylinder and with an additional screen.

Fig. 3 is a vertical sectional view of a separator with a reflective surface in the form of a portion of a rotating paraboloid without an added screen.

Examples of technical solution

Fig. 2 is a separator with a curved reflective surface, wherein the reflective surface has the shape of a parabolic cylinder and an additional screen is used in the separator. On the body 1 there is an inlet throat Π for the entry of steam with water and dirt, an outlet throat 12 for the outlet of clean steam to the turbine and a blind end 13 closed by the closure 3. A screen 5 is also inserted in the body 1 separating the inlet throat 11 from the outlet throat A curved parabolic cylindrical reflecting surface 2, attached to the closure 3, is inserted between the outlet throat 12 and the closure 3 at the end of the screen 5, and the focal line of the parabolic cylinder lies in the inlet opening of the sludge opening.

They are collected and can be removed during the outage by removing the flange blanking 4d at the lower end of the sump 4. Water flows through the drainage neck 42, Steam, which has a low inertia, branches through a sieve 5 do vý. Step 19 of the throat neck 12. The screen 5 serves to collect light and bulky impurities that have low inertia and can be entrained by steam into the outlet throat 12.

Fig. 3 shows a separator with a curved reflective surface, where the reflective surface is in the form of a part of a rotating paraboloid and the separator is without an additional screen. On the body X there is an inlet throat JT for water and dirt inlet and a blind end 13 closed by the closure 3. In the body 1, a curved reflective surface 2 in the form of a part of the rotating paraboloid is inserted between the outlet throat 12 and the closure 3, fixed to the closure 3. it passes through the interior space and bounces off the reflective surface 2 into the sludge cup 4 where they collect. The water drains through the drainage pipe 42 and solid contaminants are removed during the outage after removal of the flange blanking cap 44

4. Pure steam, which is not subject to inertia, turns into the outlet throat 12 to the turbine.

In either case, the dead end cap 13 may be formed by a tee body as shown, or by a neck flange that is bolted to the dead flange, or by a bottom welded to the better end, or by a bottom formed during machining of the body.

In both cases, the can 4 may be blinded at its lower end by a flanged blanking, as shown, or by means of a body, or a welded bottom.
