Problems solved by technology

However, in existing fluid reactors, even under ideal operating conditions, the achievable particle size distributions are not broad enough for some applications and further measures to separate the particle sizes are required

Embodiment Construction

[0013] In the context of the present invention, "collinear" refers not only to angles of 0° (in the same direction) or 180° (in the opposite direction), but also includes some deviations from this interaction angle that are visible in practice. The term "collinear" herein is intended to include interaction angles of -10° to +10°, ie, 170° to 190°.

[0014] In the context of the present invention, "collinear" means not only that the two interacting jets or nozzles are aligned or located on the same axis, but in fact includes possible displacement deviations on either side of the jet or nozzle axis. Ideally, the two jets should overlap 100%, that is, the two jets or nozzle axes are aligned. But the term "collinear" also includes overlapping ratios of 50% and above, 70% and above. The degree of this overlap also depends on the jet profile of the free jet exiting the nozzle. Those skilled in the art are aware of the relationships therein.

[0015] In the following, specific emb...

Abstract

A fluid reactor for producing particle fluid by collision, comprising: a housing (30) enclosing a collision chamber (40); a first fluid nozzle (10); a second fluid nozzle (20), and the first fluid nozzle (10) Reversely collinear, the second fluid nozzle (20) and the first fluid nozzle (10) are directly opposite in the spraying direction of the nozzles (10, 20) in a common collision area (50); at least one flushing fluid inlet (32 ), leads to the collision chamber (40), is arranged on the side (36) of the first fluid nozzle (10); and at least one product outlet (34), draws the collision chamber (40), is arranged on the second fluid nozzle (20) side (38).

Description

technical field [0001] The present invention relates to fluid reactors, in particular so-called impingement jet reactors, for the production of nanoparticles by precipitation from a fluid medium. The present invention relates to methods and means of preparing nanoparticles with a narrow particle size distribution from solution, particularly for use in chemical or pharmaceutical products. Background technique [0002] Nanoparticles of a substance or mixture of substances can be obtained by precipitation from a solution of the substance or a mixture or a precursor thereof when the liquid in which the substance or its precursor is dissolved encounters a precipitation bath under high pressure and therefore high speed . This results in atomization of the liquid and thus the formation of a precipitated product in the form of a nanoparticulate structure. One technical implementation is known as the "shock jet" method. For this purpose, it is necessary to use a fluid reactor, in ...
