Abstract

The invention relates to a centrifugal type compressor, especially to a hydrogen chloride compressor, and mainly solves technical problems that in prior art if liquid-ring compressor is employed, efficiency is low, if pressure is further increased, efficiency is lower, if diaphragm type compressor is employed, transportation capability is relatively smaller, gas transportation pressure pulsation is larger and cost is higher. The hydrogen chloride compressor includes a gear speedingup box, and a gear shaft which perforates and is connected with the gear speedingup box, and is characterized in that the gear shaft is connected with a driving device, the gear speedingup box is connected with a compression component which includes a spiral case, a spiral case inner body is arranged in the spiral case, an opening is arranged at the spiral case inner body and is connected with a inlet pipe, a impeller opposite to the inlet pipe is arranged in the spiral case inner body and is connected with a gear shaft, a medium outlet flow passage is arranged between the spiral case inner body and the spiral case, a diffuser is arranged at the medium outlet flow passage, and a gas sealing component is arranged between the impeller and the gear speedingup box.

Description

technical field [0001] The invention relates to a centrifugal compressor, in particular to an improvement on the structures of hydrogen chloride compressors and the like. Background technique [0002] Hydrogen chloride gas (HCl) is used to prepare SiHCl 3 raw material gas, while SiHCl 3 It is an important intermediate for the manufacture of silane coupling agents and other silicone products, and it is also the main raw material for the manufacture of high-purity polysilicon. Polysilicon production enterprises at home and abroad generally adopt the closed-loop trichlorosilane hydrogen reduction process. This method is to synthesize hydrogen chloride (or purchased hydrogen chloride) with chlorine and hydrogen, and synthesize trichlorohydrin and industrial silicon powder at a certain temperature. Hydrogen silicon, and then separate and rectify trichlorosilane to purify, and the purified trichlorosilane is subjected to CVD reaction in a hydrogen reduction furnace to produce hi...
