Abstract

The invention discloses a catalytic device, a compressor and a method for changing the working condition of the compressor. The method for changing the working condition of the compressor comprises the steps that a first rotor assembly of the compressor is replaced with a second rotor assembly, and the working condition of the compressor is converted into a second working condition from a first working condition. According to the method for changing the working condition of the compressor, a rotor of the compressor is replaced, the operation parameters of the compressor are changed by replacing the rotor of the compressor, the aim of changing the working condition of the compressor is achieved, other modification is not needed, and the cost for changing the working condition of the compressor is reduced.

Description

technical field [0001] The invention relates to the technical field of catalysis, in particular to a catalysis device, a compressor and a method for changing working conditions of the compressor. Background technique [0002] In the prior art, a rich gas compressor can only achieve one working condition. When the working condition of the rich gas compressor needs to be changed, the compressor needs to be newly built or replaced, resulting in relatively high equipment investment for using the rich gas compressor. high. [0003] Therefore, how to reduce the investment of the equipment using the rich gas compressor has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides a method for changing the working condition of the compressor, so as to reduce the investment of the equipment using the gas-rich compressor. The invention also provides a compressor and a catalytic d...
