Method for mixing a liquid in a sealed container with a fine-particle solid, container of this type, ejector jet and use of a jet of this type

Abstract

The invention relates to a method and a device for mixing a liquid in a substantially sealed container or a mixture of a liquid and a fine-particle solid, said liquid or mixture only partially filling the internal volume of the container that can be occupied by a fluidic phase and the remaining available internal volume of the container being filled by a gaseous phase. According to the invention,the essentially same liquid or mixture is fed to the container in the form of a propelled stream of a suction device that is situated in the liquid or mixture in the container. In its simplest form, the method according to the invention is implemented by means of an ejector (i.e. according to water jet pump principles) embodied as the suction device. The propelled stream is pumped through a propelling nozzle, which is fitted into the ejector in such a way that gas is sucked from the gaseous phase during the passage of the stream through the nozzle, e.g. by means of a riser tube that projects into the gaseous phase of the container, and is released in the form of dispersed gas bubbles, together with the propelled stream, into the liquid content of the storage container.

Description

technical field [0001] The present invention relates to a method of mixing a liquid or a mixture of liquid and fine-grained solids present in a substantially closed container, with the proviso that the liquid or mixture fills only a part of the internal volume of the container that the fluid phase can occupy, and that the container The remaining occupiable internal volume is filled by the gas phase, the method comprising supplying substantially the same liquid or substantially the same mixture into the container in the form of a powered jet of a suction device arranged in the liquid or mixture of the container. Background technique [0002] The storage of liquids or mixtures of liquids and finely divided solids in substantially closed containers, eg for storage purposes, is known. Often, these containers are also called cans. As a rule, these containers are not completely airtight, but typically have, for example, at least one extraction point via which the content stored i...

Together with the suction acting from below, the formation of effluent upwards out of the momentum exchange tube has the basis of Figure 5 A large-volume circulating flow field with continuous field lines, with the spray nozzles slanted upwards and preferably mounted slightly elevated in the tank (see, for example, Acrylate Esters, A Summary Of Safety And Handling, 3rd Edition, 2002, Compiled by Atofina, BASF, Celanese, Dow and Rohm & Haas), the effluent can produce improved (especially more complete) mixing compared to powered nozzles, however, it is still not completely satisfactory
