A thin-film treatment apparatus for treating viscous material includes The rotor shaft includes at least one lift element arranged on the rotor shaft body, for producing a lifting force in the direction of the rotating rotor shaft body.

Thin-layer treatment device

Modular microreactors are provided composed of microreactor parts including a plate body which has, on one plate side, a groove-shaped depression in which a reactor tube is accommodated, and the reaction tube has connection ends on the outer sides of the plate body. Also disclosed are reaction tubes for turbulent mixing, kits for producing the reactors and the use thereof for commencing chemical reactions.

Modular reactor

A method and a device for cleaning a fluid is provided, the device including a housing having at least one inlet and at least one outlet, and a slide mechanism which is movable in the housing and has at least one passage having at least two filters lying substantially symmetrically opposite each other, wherein starting from the housing inlet the fluid flows symmetrically onto the filters in the passage and downstream of the filters is directed to the outlet of the housing, wherein a part of the fluid that does not flow through the passage forms a hydrodynamic buffer in a gap between the slide mechanism and the housing, wherein the passage opens out into at least two symmetrically opposite sub-channels of the outlet and at least four flushing flows are generated in the gap between at least two inlet mouths and at least two outlet mouths of the passage.

Method for the purification of a fluid and filtering device

The invention relates to a method and a device for producing Lyocell fibers which are extruded from a cellulose solution of water, cellulose and tertiary amine oxide in a spinning head (). The cellulose solution is obtained in a number of process steps directly from the cellulose () or with the formation of a cellulose suspension. Since the degree of polymerization decreases in the course of processing the cellulose through to its extrusion in the cellulose solution, with the processing of celluloses with a low degree of polymerization there is the risk that the endless molded bodies () extruded in the spinning head () exhibit defective quality. In order to also be able to process celluloses () with a low degree of polymerization without having to accept reduced quality, according to the invention, the residence time of the cellulose from its introduction into the device () through to the extrusion of the cellulose () in the cellulose solution is set in dependence of the degree of polymerization of the cellulose, of the cellulose suspension and/or of the cellulose solution.

The present invention relates to a buffer tank as is substantially used for ensuring a constant supply of the spinning machine with a polymer melt in spinning machines. To this end the buffer tank is provided with a compensation chamber whose volume is variable in response to a pressure prevailing in the polymer melt and to a volume flow variation. The polymer melt flows from a polymer melt entry opening to a polymer melt exit opening through the compensation chamber. It is the object of the present invention to make the flow through the compensation chamber uniform. The residence time of the polymer melt in the compensation chamber shall thereby be prevented from having a wide range, the latter resulting in an irregular quality of the yarns produced by the spinning machine because of the time-dependent, mechanical and chemical properties of the polymer melt. To achieve said object, the compensation chamber is provided for flow optimization with at least to one flow guiding element projecting into the flow of the polymer melt, which is smaller than the flow cross-section of the compensation chamber and by which the velocity profile in the direction of flow through the compensation chamber is made uniform at least in sections.

Buffer store for polymer melts, especially cellulose solutions

A device is disclosed to draw off or store viscous mass which is discharged from a process for example as a result of exothermal events. The device contains at least one unit which has one inlet for the viscous mass and one outlet and is at least partly filled with a non combustible liquid inert to the viscous mass. The unit can be in the form of a pipe or a receptacle. Preferably several units in the form of a pipe can be connected one with the other respectively with a unit in the form of a receptacle. The solution discharged can then be transported via the pipes to the receptacle.
