System for testing energy efficiency of vortex tube heating natural gas

Abstract

The invention provides a system for testing the energy efficiency of vortex tube natural gas, and belongs to the technical field of pipeline systems. The system for testing the energy efficiency of the vortex tube heating natural gas comprises a pressure adjusting unit, a data acquisition unit and a gas source, the pressure adjusting unit comprises a gas supercharger and a first pilot pressure reducing valve, and the gas source is communicated with a vortex inlet of a vortex tube heater to be detected. The inlet of the gas supercharger is communicated with the vortex outlet of the vortex tube heater, the gas source is communicated with the first pilot inlet of the vortex tube heater, and the data acquisition unit comprises a first pressure sensor, a second pressure sensor, a first temperature sensor and a second temperature sensor. Different working conditions are simulated through the pressure adjusting unit, the energy efficiency of the vortex tube heater for heating natural gas is accurately tested through the data acquisition unit, whether the vortex tube heater can meet the heating requirements of application working conditions or not is checked, and the working efficiency is improved.

Description

technical field [0001] The disclosure belongs to the technical field of pipeline systems, in particular to a test system for the energy efficiency of natural gas heated by vortex tubes. Background technique [0002] With the continuous improvement of the national economy, the demand for natural gas in various domestic industries is also increasing day by day. In the process of natural gas transportation, natural gas is generally transported through high-pressure long-distance pipelines, and then the high-pressure natural gas is depressurized by skid-type regulators. After processing, it will be delivered to downstream urban users. Limited by the performance of the skid-type regulator, the "throttling effect" is inevitable in the process of pressure regulation. In the season with low temperature, the "throttling effect" can easily cause the phenomenon of "ice blockage" in the skid-type regulator . [0003] In the related art, a vortex tube is generally used to solve the abo...

Problems solved by technology

[0004] However, since the heating effect of the vortex tube is greatly affected by the transmission pressure and temperature of the natural gas, and different types of vortex tubes have different heating effects on the natural gas, if the vortex tube is directly tested without testing If it is used on a natural gas skid-type regulator, it cannot guarantee that the vortex tube can meet the actual heating requirements, resulting in "ice blockage" in the skid-type regulator
