Pressure reducing device with temperature recovery function

Abstract

The invention relates to a pressure reducing device with a temperature recovery function. The pressure reducing device is applied to occasions where high-pressure compressible fluid needs to be converted into low-pressure fluid through throttling, and obvious temperature reduction is not allowed to occur, and belongs to the field of energy conservation and utilization. The pressure reducing device comprises an intake flange (1), an intake straight section (2), a laval nozzle taper section (3), a laval nozzle divergent section (4), a straight section (5), a diffusion section (6), a discharge straight section (7) and a discharge flange (8) which are connected continuously. The device has very broad pressure reduction range, has a compact structure and no moving parts, and is not easy to crack or leak.

Description

technical field

[0001] The invention relates to a novel decompression device with temperature recovery function, constant flow rate and self-adaptive back pressure capability and a design method thereof. It is mainly used in occasions where high-pressure compressible fluid needs to be changed into low-pressure fluid through throttling and no obvious temperature drop is allowed, and belongs to the field of energy-saving utilization. Background technique

[0002] In various production and processing processes such as petrochemical, power engineering, gas transportation and processing engineering, it is often necessary to convert high-pressure compressible fluids into low-pressure fluids to meet the requirements of downstream production processes. For example, the fluid produced from natural gas wells often has very high pressure and cannot directly enter the gathering and transportation system. It must be reduced to the allowable pressure of the gathering and transportation sy...
