DE20314963U1 - Coalescence packet for removing liquid mechanically emulsified discontinuous secondary phase from liquid main phase comprises rectangular or square frame, inlet part, and outlet part - Google Patents

Abstract

A coalescence packet comprises a rectangular or square frame (1) made from plastic or metal, an inlet part (2) made from plastic or metal, and an outlet part (3) made from plastic or metal. Fiber packings (4) and a foam breaker material (5) are arranged between the inlet and outlet parts. Fine droplets of the discontinuous phase coalesce on passing through the packings and exit as large drops without very fine particles impairing the coalescence or without short-term blocking of the packings.

Description

The invention relates to a Utility model no .: 297 09 633.8 of the applicant with the no .: 4960 165 With the difference of the construction, since no element in filter form, but a square, rectangular or polygonal package for separation a liquid discontinuous secondary phase from a liquid main phase is used. This Package consists of a frame, an entry and exit part and the fiber package together.

When separating two liquid phases, whereby each phase can consist of different liquids partly mechanical emulsions, since the secondary phase in the form of drops <1 μm in diameter is present. With the flow of such a phase mixture through the fiber packet wet the liquid drops the discontinuous phase the fiber surfaces and form with increasing flow path one with the main flow liquid film migrating to the outlet side, the itself inside and at the exit from the fiber layer as a large, spontaneous separating drops. A foam-breaking material lying on the fiber material prevents doing a possible one Foaming, both from the composition of the discontinuous Secondary phase, as can also result from air entry and the replacement and hinder the rise or fall of the coalized drops.

The well-known coalescence mats, or Coalescence plates have the disadvantage that they are used in many industrial applications Processes, as well as in the treatment of wastewater and bilge water only can only be used to a limited extent because in particular the fiber packs used, Knitted fabrics or foams are not suitable for liquids, the continuous secondary phase is very dirty or highly viscous and this negatively affects efficiency and economy.

The invention has for its object phase separation packets with a coating layer made of fibers, in particular glass fibers, Metal fibers, natural fibers or monofilament plastic fibers and a special foam breaking material to improve the fiber packs not only largely insensitive to pollution and air influences but their chemical and thermal properties are improved be and additional gravitational forces develop that to separate the from the discontinuous phase surrounding the finest dirt particles.

This object is achieved according to the invention solved, that processed in the fiber packs and foam breaker material Fibers are selected in material, structure and density structure that with a big one Pore size at the same time a very high wetting behavior of the fibers for one high coalescence and thus a separation of the discontinuous Phase up to the solubility limit is achieved.

Claims (7)

Coalescence package based on utility model No. 297 09 633.8 (owner is the applicant), for separating a liquid, mechanically emulsified, discontinuous secondary phase from a liquid main phase, which is composed of a rectangular or square frame made of plastic or metal ( 1 ), an entry part made of plastic or metal ( 2 ), an outlet part made of plastic or metal ( 3 ). Between part ( 2 ) and ( 3 ) arranged in several layers and mechanically - physically / chemically connected fiber packs ( 4 ) and foam breaker material ( 5 ), characterized in that the fiber packs are constructed in terms of fiber diameter, porosity and bed volume such that the fine drops (in the micrometer range) of the discontinuous phase coalesce in the fiber bed when flowing through the pack from the inlet to the outlet side and emerge as large drops without this very fine solid particles lead to impaired coalescence or premature blockage of the package. Coalescence package according to claim 1, characterized in that the fiber packs ( 4 ) consist of organic and inorganic fibers, the surfaces of which are clean and untreated and which, owing to their processing and wetting behavior, are suitable both for separating an organically disperse phase from an aqueous phase and for separating an aqueous disperse phase from an organic main phase. Coalescence package according to claim 1, characterized in that the fiber packs ( 4 ) consist of oleophilic fibers if the separation of hydrocarbons from an aqueous solution or water / waste water is required, or the fiber packs consist of hydrophilic fibers if the separation of water or aqueous solutions from hydrocarbon compounds is required. Coalescence package according to one of the claims 1 to 3, characterized in that the cross-sectional area of the Fiber pack has a packing depth of at least 50 mm. Coalescence package according to one of the claims 1 to 4, characterized in that the fibers have a diameter of 1 μm to 150 μm and are not connected by binders but by thermal or mechanical methods are connected. Coalescence package according to one of claims 1 to 5, characterized in that the porosity of the fiber packs ( 4 ) inversely proportional and in a precisely calculated ratio decreases with increasing fiber diameter, thereby ensuring the stability of the fiber packing even at high flow (differential) pressure.
