Problems solved by technology

In these cases, on the one hand, the depressurization of the high-pressure gas causes a loss of pressure energy, and the boost of the low-pressure gas increases the power consumption.
Traditional pressurization and depressurization must rely on mechanical devices (such as compressors, expanders) to achieve energy transmission, which is an indirect energy transmission method, which greatly reduces the utilization rate of energy

Abstract

The invention relates to the field of natural gas pipeline conveying, and particularly discloses a natural gas injection pry which comprises a high-pressure gas pipeline, a low-pressure gas pipeline, a bypass pipeline and a control device. The high-pressure gas pipeline comprises a first pipeline, a first control valve, an ejector, a first flow meter and a second control valve, the first control valve, the ejector, the first flow meter and the second control valve are sequentially arranged along the first pipeline, the end, close to the first control valve, of the first pipeline communicates with a high-pressure gas source, the other end of the first pipeline communicates with a downstream pipeline, and a contraction section is arranged in the ejector. The device is integrally skid-mounted, has the characteristics of compact structure, space saving and convenience in removal, and plays a role in pressure energy utilization in the natural gas conveying process.

Description

technical field [0001] The invention relates to the field of natural gas pipeline transportation, in particular to a natural gas ejector skid. Background technique [0002] As one of the important energy sources in the 21st century, natural gas plays an important supporting role in national economic construction. In the process of natural gas extraction, transportation and sales, natural gas needs to be reasonably adjusted and transported in many stages. In the process of natural gas exploitation, due to the difference in development layers and time in the gas field, high-pressure gas wells and low-pressure gas wells often exist at the same time. In order to meet the export requirements, the high-pressure gas needs to be throttled, and the low-pressure gas needs to be pressurized. During the transportation of natural gas, the normal maintenance and venting of natural gas in the gas transmission station is low in pressure and cannot be directly recycled into the pipeline ne...
