Embodiment Construction

[0021] Examples of reactor systems for producing reaction products are in figure 1 The population in the middle is labeled "5". The reactor system 5 includes a reactor liner 17 ( figure 2 ), defining a reaction chamber 15 in the reactor liner for receiving the reaction components. The liner 17 may comprise separate sections connected by gaskets to seal the various sections. The casing 20 surrounds the reactor liner 17 and forms the annular chamber 12 between the reactor liner 17 and the casing 20 . Sealing plate 11 or reactor "head" seals reaction chamber 15 and annular chamber 12 to separate the fluids in each chamber.

[0022] The clamping device includes a plurality of actuators 29 ( figure 1 ), which fixes the sealing plate 11 by exerting a clamping force between the sealing plate 11 and the bushing 17 and the housing 20, thereby sealing the annular chamber 12 from the reaction chamber 15. The clamping device generally resists hydraulic end forces from the reaction c...

Abstract

A clamping device for sealing an annular chamber and a reaction chamber of a reactor system is disclosed. The clamping device may comprise actuators arranged symmetrically in two or more independently controllable actuator groups.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Nonprovisional Patent Application 14 / 709,856, filed May 12, 2015, the entire contents of which are hereby incorporated by reference in their entirety. technical field [0003] The field of the application relates to clamping devices, in particular for sealing annular chambers and reaction chambers of reactor systems. Background technique [0004] Polysilicon can be produced economically and on a relatively large scale by thermally decomposing thermally decomposable silicon-containing compounds such as silane, trichlorosilane or dichlorosilane in fluidized bed reactors. This polycrystalline silicon can be used for the production of solar cells, or it can be further processed according to the so-called Czochralski process to produce electronic-grade monocrystalline silicon. [0005] Recent advances in polysilicon production involve the use of higher reactor pressures (eg 2 bar or h...
