Through this inventive design of the separator it is achieved that the separation of liquids from the gas stream in two stages is effected, in the first of which the separation of most of the liquid t-streams suspended in the Gc'.ss'jrom mechanical layers, and in its second stage absorption of existing vapor and the remaining liquid droplets takes place. Included The hollow vessel of the separator is opened through one with one or more openings The membrane is divided into an inlet and an outlet chamber, this opening (s) are covered by means of agglomeration of the droplets, while adsorbent are arranged around the outlet opening. According to another advantageous Features of the invention are between the means for agglomeration of droplets and the adsorbent means for directing the gas stream in a tortuous flow path intended. further features and advantages of the invention are exemplified below and described with reference to the drawing without restrictive significance. Show it : Fig. 1 in side view partially cut and broken off an embodiment a separator according to the invention; Fig. 2 section through. one of the invention Means for agglomerating liquid droplets in a separator according to FIG. 1 ; Fig. 3 is a section along the line 3-3 in Fig. 1, and Fig. 4 is a section along fin 4-4 in FIG. 1.

That in Si. 1 shown embodiment shows a separator 10, which is used to separate liquids such as oil or the like from a gas stream. It consists of an essentially cylindrical metal bar 11, which is attached to a the upper end is tightly closed by means of a sealing cover plate 12; these is removable and is held in place by means of screw bolts 35.

The lower end of the tank 11 is provided with an annular closure plate 13 completed, which in a suitable manner with its outer edge tightly with; the tank 11 is connected and is attached to an outlet line 14 with its inner circle. also has the tank 11 on his. the upper end of an opening 15, which for Receiving the end of an inlet line 16 is used, so that the tank 11 in the treating Gas flow can be switched on.

Inside the tank 11 forming a hollow vessel is one of a Steel plate 17 arranged existing membrane below the opening 15 through the the hollow vessel is divided into an upper inlet chamber 18 and a lower outlet chamber 19 will. This steel plate tte 17 is held by a circular ring 20 on the inside the tank 11 is welded on. Between ring 20 and steel plate 17 is a sealing ring 21, whereby the inlet chamber 18 is sealed against the outlet chamber 19 will.

Inside the obaren inlet chamber 18 are through the steel plate 17 carry a number of droplet aggregation units 22 g. Within the An adsorption unit 23 is provided in our outlet chamber 19.

As can be seen from Figures 1 - 3, the membrane serving as a membrane Steel plate 17 has a number of openings 24, in the short pipe socket 25 are welded in, which are used to hold the agglomerated droplets 22 serve. These pipe sockets 25 are a @ f an @ussenkreis and a Zv'ischenkreis arranged, which are essentially concentric to one in the IIi'J-th Pipe socket 25 lie-; en.

The length of the pipe socket 25 increases from the outside inwards, so that the aggregation units 22 are considerably wider than the distance between the concentric lrjisenau - \; e formeb can be, as otherwise the case w.re.-read..usbildn allows the units 22 can be staggered and arranged overlapping one another (see Fig. 1 and 3).

Jade droplet agglomeration unit 22 consists of a support member 26 and a z-agglomeration element 27./ @as lr @@@ eil 26 consists of an oil-indi'jen material, such as silueie Heoprene rubber or u ~ l. and has a bottom section 28 and a top 29. The Bodenaoschnitt 28 is provided with a @ zial @@ irrigation 30, the sat @ on the upper one The end of the tube 25 is picked up, as well as a section 31 with reduced @diameter on his obscene @cde, which protrudes over the upper @hae of the 2ohrscutzen 25, forms a seal and thereby changes @. that the ras to be treated unselejnt next to the additional ball27 can flow past. The upper part 29 of the support part 26 has essentially a cup-shaped training and is with a generally annular shoulder 32, so that the agglomeration element 27 is kept in a slightly increased cellung content becomes the agglomeration element, in order to give the gas to be handled to be able to flow through all of its files.

Each lump @sslenent 27 is surrounded by a ring-shaped @etalli @hen version 33 includes, which gives this the necessary hold. On the inside of the cup-like T-part 29 of the support part 26 is a pair von Ringripe) or webs 34, which are used for flexible and sealing @@@@@@@@@@ e der Outside of version 33 are used.

The droplet agglomeration element is made of a material that has extremely fine pores, the size of which is generally less than one in microns ; it can be made of any porous catarial, such as sintered metal, be made of cellulose material or the like.

The adsorption device 23 consists of a one-color concentric, inside and @@ ssen @ perforated metal cylinders 36 and 37, which are supported by an upper metallic @ndkappe 39 and a lower metallic. E40halen, every ede of these Kanpen 39, 40 has an integrally formed ring 41 which is there aient, @ie @ylimder 36, 37 concentrically to keep them at a distance from each other and at the same time to seal the ends of the same. The t rlinder-ri 36 and 37 is filled with a porous JOTbes3S, such as activated @onerae, aicytiv- @ ohle oider like mahr.

@ie Ausl. @ ssleitung 14 extends concentrically into our end of the Hollow vessel 11 and further through an inner opening 42 in the lower misc. flow part 13 through. A flat metal ring 44 is suitable Way inside the hollow vessel 11 at the outlet line 14 below the upper one Attached end and used to hold the adsorption unit 23. Between the lower Closing cap 40 of the adsorption unit 23 and the flat I.: metal ring 44 a seal 45 is arranged to allow gas to flow past the adsorption unit 23 is prevented. In this way it is achieved that the adsorption unit 23 and the land of the outlet conduit is arranged raised above the bottom of the hollow vessel 11 thereby creating a basin for collecting the liquid.

When oil is to be separated from a gas, the gas contains, as before which enters the upper inlet chamber 18 through the F inlet line 16, Oil in vapor form and in the form of suspended oil droplets. the river flowing through the oil-containing gas caused by the various droplet agglomeration elements 27, that most of the suspended oil droplets are cracked and agglomerated together in Berä when the gas flows through the porous material of these elements. The agglomeration effect on the oil causes this, in proportionally large drops of the Units 22 to drip off and through the pipe socket 25 into the lower outlet chamber 19 and there to run along the sides of the hollow vessel 11 and onto ours Closing plate 13 to get from where it is through a line 46, the end of which in a suitable opening 47 is attached in this closure plate 13, can be removed can. On the other hand, since the upper end cap 39 of the adsorption unit 23 is not perforated is, the oil-laden gas that through the pipe socket 25 and the @openings 24 in serving as a membrane metal plate 17 flows through, his Change the direction of flow and flow radially outward before it passes through the perforation in the outer cylinder 37 of the Adsorptionseinhaib 23 can flow through. This will ensures that all agglomerated ultra-drops that are still in the Gassbrou tend to touch the inner wall of the hollow vessel 11 and then to there Bottom closure plate 13 to flow down.

This agglomeration has the effect that only oil vapor is left in the gas stream and relatively small oil drops remain. o After passing the gas flow through the agglomeration units 22, the latter flows through the openings in the Ausson cylinder 37 of the adsorption unit 23, the adsorbent 38 and the perforations in the inner cylinder 36 of the adsorption unit 23 and from there it reaches the outlet line 14. The Oil vapor is released by contact with the adsorbing surface of the adsorbent 38 deposited immediately. In addition, it is through the winding flow path Significantly increases the likelihood of the remaining smaller oil droplets come into contact with the adsorbent 38, so that these too are separated from the gas flow will.

It follows that a two-stage designed according to the invention Oil separator separates the whole oil from a gas stream in an effective way. Most of the oil droplets are through the agglomeration elements 27 and the entangled flow path separated between these and the adsorption unit 23, while the relatively smaller oil droplets and oil vapor in the adsorption unit 23 are deposited. j = i18 (f'1: 1;.;.

However, since the oil vapor and the extremely small Droplets only have a small percentage of the total oil content of the gas flow make up is due to the inventive arrangement and design of the agglomeration elements 27 and the inventive design of the flow path of the gas stream in Separate the separator 10 compared to known separators quite considerably extended.

On the opposite sides of the membrane 17 are. Jruck knife 48 is provided for the hessen of the pressure drop in the agglomeration units 22 these will preferably accumulate on agglomeration units 22, whereby an increased pressure drop across the diaphragm 17 arises. If this pressure drop reaches a predetermined:: ert, the replacement of the agglomeration elements 27 can be indicated be.

The life of the agglomeration elements 27 can, however, be substantial be increased if within the inlet line 16 a filter 49 to the previous one Filtering off such solid particles from the gas stream is provided.
