Abstract

The invention discloses an intelligent power generation and pressure regulation box for a natural gas pipeline network. The intelligent power generation and pressure regulation box for the natural gas pipeline network comprises a box body, a pressure regulation unit and a power generation unit, wherein the pressure regulation unit and the power generation unit are arranged in the box body. The pressure regulation unit comprises a first flow regulation valve, a first flowmeter and a first pressure regulator which are sequentially connected to a pressure regulation pipeline in series from upstream to downstream. The power generation unit comprises a second flowmeter, a second flow regulation valve, an expansion device and a second pressure regulator which are sequentially connected to a power generation pipeline in series from upstream to downstream. A power output shaft of the expansion device is connected with an input shaft of a power generator. Power generated by the power generator is used for providing power support for electric equipment. The pressure regulation pipeline and the power generation pipeline are connected in parallel and provided with a common upstream input end and a common downstream output end. The intelligent power generation and pressure regulation box has the advantages of being simple in structure, convenient to install, stable in operation and high in intelligentization degree, and the problem that according to a traditional fuel gas pressure regulation box, remote transmission of data and monitoring cannot be achieved due to power shortage can be effectively solved.

Description

technical field [0001] The invention relates to a power generation equipment, in particular to a power generation pressure regulating box which is used in a natural gas pipeline network and has two functions of power generation and pressure regulation. Background technique [0002] In the field of natural gas exploitation and use, it is first necessary to use high-pressure pipelines to transport natural gas over long distances to various gate stations in the city, and then adjust the pressure of natural gas to medium and low pressure through pressure-regulating stations or pressure-reducing equipment such as pressure-regulating boxes before transporting to downstream users. Not only will a large amount of pressure regulation noise be produced during the depressurization process, but also a large amount of pressure can be wasted in vain. If this part of the pressure can be effectively recycled, it will produce better economic and social benefits. [0003] The current natura...
