Abstract

The invention discloses a temperature and pressure balance device applied to a natural gas pressure energy power generation process. The temperature and pressure balance device comprises a main tank body, and a plurality of hollow groove pipes which are filled with phase-change energy storage material and are arranged at intervals in the circumferential direction of the main tank body. According to the temperature and pressure balance device, cold energy in low-temperature natural gas is absorbed through the phase-change energy storage material, so that the temperature at an air outlet pipe ofthe main tank body of the natural gas meets the temperature requirement of entering a downstream pipe network, and irreversible influence on a valve and equipment of a subsequent pipeline is prevented; and meanwhile, a shaft rod sleeved with a suspension ball is fixedly arranged in the interior of the main tank body, and the flow area of the main tank body is changed through front-and-back movement of the suspension ball in the extension direction of the shaft rod according to the stress condition, so that the resistance coefficient of fluid flowing through the main tank body is changed, andadjustment to mutation pressure of the fluid is achieved.

Description

technical field [0001] The invention relates to the technical field of natural gas pressure energy utilization, in particular to a temperature-pressure balance device applied to the natural gas pressure energy power generation process. Background technique [0002] In recent years, due to industrial, civil and environmental protection requirements, the construction of natural gas pipelines in my country has entered a period of rapid development. It is estimated that by 2020, more than 20,000 km of new natural gas pipelines will be built, and the annual transportation volume will reach 4200×108Nm 3 above. During the process of natural gas being transported by high-pressure pipelines to users, it contains huge pressure energy resources that can be developed and utilized. [0003] The pressure energy contained in the natural gas transportation process is often used for power generation, but in power generation projects, there are mainly problems of low temperature of the fluid...
