Decompression expansion trubo-generator set

Abstract

The invention relates to a decompression expansion trubo-generator set, which comprises a shell and a turbine held in the shell. The shell comprises a pipeline air inlet and a pipeline air outlet. The generator set comprises a generator in drive connection with the turbine; the generator is held in the shell. A valve core can also be arranged on the upstream of the turbine; input pipeline air channels can be defined on the outer surface of the valve core and the inner surface of the shell; the valve core can move on the axial direction of the turbine relative to the turbine so as to change the cross section area of each input pipeline air channel.

Description

technical field

[0001] The invention relates to a generating set using fluid to generate electricity, in particular to a decompression expansion turbine generating set using pipeline gas to generate electricity. Background technique

[0002] In the prior art, there is a technology of using pipeline gas to drive a turbine and then drive a generator to generate electricity. In this known arrangement, the turbine is arranged in a closed casing, the inlet and outlet of which are connected to upstream and downstream piping. The generator is arranged outside the casing, and is connected to the turbine through the rotating shaft to generate electricity. Due to the huge pressure difference between the inside of the pipeline and the outside of the pipeline, there is a risk of pipeline gas leakage at the connection between the closed housing and the rotating shaft. Contents of the invention

[0003] In view of this, this paper proposes a decompression expansion turbogenerator set ...
