Beschreibung
Zusammenfassung:	The invention discloses a natural gas pipeline anti-freezing device and method for releasing heat through pressure energy. The natural gas pipeline anti-freezing device is composed of a natural gas inlet pipeline, a convergent-divergent spray pipe, a separating device, a water vapor collecting device, a front step pipeline, a convergent spray pipe, a natural gas outlet pipeline, a separating type heat pipe and a shell. The device is placed on the open ground, natural gas of a gas well is introduced from the inlet pipeline, and natural gas pipeline heating and freezing prevention can be achieved through comprehensive utilization of the convergent-divergent spray pipe and the front step pipeline by means of the high pressure of the natural gas. High-speed natural gas is obtained through high pressure of the natural gas, a large amount of heat is generated by the natural gas in a speed-reducing and temperature-increasing mode, and compared with a traditional natural gas anti-freezing method, pipeline anti-freezi
