Description

GERMAN

The invention relates to a cyclone separator for separating liquid droplets from flowing Gases or vapors with a vortex space with a tangential inlet for the gases or Vapors and a central discharge pipe for the purified gases or vapors at the top is.

While with dust separators, the dust particles thrown against a wall do not flow together and do not form a closed, flowing layer, is formed in cyclone separators for separation of liquid droplets from flowing gases or vapors on the walls of the vortex chamber a layer of liquid that not only flows down, but also under the influence of the significant pressure differentials in the chamber along the upper inner surface of the separator in the direction flows to the gas or steam outlet. These strive towards the center of the separator both at the top and at the bottom Liquid particles are moved by the rising gases in the direction of the gas or vapor outlet partly picked up again and taken along.

Cyclone separators of the aforementioned type have already been known for those in the vortex space Organs are present that prevent the flow of fluids from settling on the walls of this room Liquid in the direction of the cyclone axis towards the discharge opening for the cleaned gases or vapors distract and inhibit.

However, these organs were only so imperfectly formed in the cyclone separators known up to now or arranged that part of the precipitated on the surfaces of the vortex chamber and to The liquid reaching the inhibiting organs also got into the outlet stream of the gases or vapors and was taken away by him.

In the case of the cyclone separators known to date, this entrainment of the liquid droplets did not take place only in the upper part of the swirl chamber near the outlet, but with the conical design of the lower part of the vortex chamber from bottom to top, as there is to the axis of the cyclone separator flowing liquid particles partly by ascending gas flow to the upper outlet were taken there.

The invention makes cyclone separators for separating liquid droplets from flowing Gases or vapors are significantly improved by the fact that on the inside of the upper wall of the vortex space a protruding ring at some distance from the discharge pipe around this central pipe is arranged, wherein the lower edge of the ring extends at most to the upper surface of the inlet channel and im a flat disc cyclone separator in the lower part of the vortex space

is provided, the scope of which is completely free of the inner wall of the vertebral space and the upper Dividing the separator is so that between this perimeter and the inner wall, as is known, a free annular gap is located.

The effect of the cyclone separator can be further improved in that the discharge pipe of the Vortex space leads into a second vortex space, the discharge pipe also with a protruding one Ring is provided.

By the cyclone separator according to the invention is achieved that the on the inner wall of the The fluid layer on it that collects the vortex space and moves in the direction of the axis of the separator is prevented from getting into the flow area of the cleaned extracting gases or vapors, so that no drops of liquid are again taken up and entrained by the withdrawal stream.

Rather, in the upper part of the separator, the layer of liquid that reaches the walls outside of the discharge flow is previously used Brought to drain, while a disc in the lower part of the separator ensures that none Liquid particles are entrained by upward currents.

In the drawings, two exemplary embodiments of the cyclone separator according to the invention are shown. It shows

Fig. 1 is a schematic longitudinal section of a first embodiment,

Fig. 2 shows a cross section along line AB in Fig. 1 and

Fig. 3 and 4 a schematic longitudinal section and a cross section along line CD in Fig. 3 of a second embodiment.

In the two exemplary embodiments, the gases to be cleaned pass through a tangential supply line 1 into a cylindrical vortex chamber 7 which is provided with a central discharge pipe 3 for the dried gases at the top and a liquid outlet 5 at the bottom. A protruding ring 2 is arranged around the pipe 3 on the inside of the upper wall of the vortex chamber at a distance from the discharge pipe 3. This ring lies outside the discharge flow and interrupts the flow of the liquid film which is formed along the top wall of the separator from the outside to the inside, i.e. in the direction of the discharge pipe 3. The film that is intercepted by the ring also comes at the lower edge of the ring in an area with a strong swirl of the gases, therefore in an area with a strong Sehleuderkraftfeld, so that the film at the lower edge of the ring largely in shape is thrown outwards by drops. The liquid thrown against the inner wall of the cyclone separator is not prevented from flowing downwards. Since a flat disc 4 is arranged below in the vortex space, it is ensured that a completely free passage gap for the liquid is present between this disc 4 and the inner wall of the vortex space, such that the liquid along the wall of the vortex space and over the The entire circumference of the separator can flow downwards unhindered and cannot reach the disc 4.

It has been shown in practice that, even if larger quantities of liquid are used, together with the gases are fed, the collected liquid is quickly conveyed downwards and the disc 4 remains practically dry. Because the pressure at the circumference of the vertebral space has a maximum value, it is called A secondary advantage is a small pressure difference between the gas inlet and the liquid outlet achieved, whereby the drainage of the liquid is facilitated.

In the embodiment according to Figs. 3 and 4, the discharge pipe 3 of the vortex space 7 opens into a second vortex space 6, which is provided with a liquid outlet 9 on the underside and with a ring 2 °, which has the same effect as the ring 2 in the first Has whirl space. This ring 2 ", as the ring 2 to the central discharge pipe 8 of the second cyclone chamber arranged around. The height of the rings 2 and ^2a is smaller than the penetration depth of the discharge pipe 3 and 8, and the lower edge of the ring 2 extends at most up to the top of the supply line 1.
