Problems solved by technology

There are also natural gas differential pressure power generation to generate electricity and cold energy for ice making, but the amount of ice making is too large to be consumed
[0005] The existing technology for heating low-temperature natural gas after high-pressure natural gas depressurization generally uses a heating furnace to heat the depressurized low-temperature natural gas, but there are the following technical defects: the heating furnace consumes natural gas during the heating process, resulting in high energy consumption
At the same time, the pressure energy and cold energy of natural gas are not utilized

Embodiment Construction

[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] Research institutes predict that cloud computing will grow rapidly at an annual growth rate of 26% in the next few years, which is five times faster than the growth rate of the traditional IT market, which fully reflects the vitality of the cloud industry. In today's informatization, all walks of life, whether it is the government, enterprises or individual users, are optimistic about the endless potential contained in cloud computing. An informatization revolution led by cloud computing is in full swing around the world. However, Behind the powerful computing power of cloud computing, the problem of high energy consumption inevitably arises. In 2011, the total power consumption of my country's data centers reached 70 billion kWh, accounting for 1.5% of the electricity consumption of the whole...

Abstract

The invention discloses a natural gas pipeline network variable-voltage generation and cooling system and method. The system comprises an expander, a gearbox connected with the output end of the expander, a generator driven by the gearbox, and a heat exchanging device, wherein the gas inlet of the expander is connected with a high-voltage pipeline network; the generator powers power and cooling consuming equipment such as high-power-consumption cloud computing servers requiring to be cooled; one end of the heat exchanging device is connected with the gas outlet of the expander, and the other end of the heat exchanging device is connected with a lower-stage pressure pipeline network; heat-exchanged coolant flows through a cold blast device to cool the power and cooling consuming equipment. The natural gas pipeline network variable-voltage generation refrigerating system can generate power through pressure generated due to expansion of natural gas and supply power for power consumption equipment, thereby omitting an intermediate power grid and saving investment; cold energy of post-generation low-temperature natural gas can be recovered and supplied to cooling consuming equipment; due to the fact that coolant heat exchanging can increase the temperature of natural gas, electricity-consumed or natural gas-consumed heating can be omitted or saved, and energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of differential pressure utilization of a natural gas pipeline network, in particular to a natural gas pipeline network pressure regulating power generation refrigeration system and a method thereof. Background technique [0002] Natural gas is a clean energy widely used in the world at present. In order to meet the needs of long-distance natural gas transmission, it is necessary to apply high pressure to natural gas. The design pressure of my country's "West-to-East Gas Pipeline" pipeline, the Shaanxi-Beijing line and the second-line system, and the Hebei-Ningbo connecting line gas pipeline has reached 10MPa, and the design pressure of the second-line West-to-East gas pipeline can reach 12MPa. After the high-pressure natural gas transported by the high-pressure pipeline network arrives at the natural gas receiving gate stations in various cities, it enters the lower-level pressure pipeline network after bei...
