Mixed containing cavity heat dissipation gas wave refrigerating machine

Abstract

The invention relates to a mixed containing cavity heat dissipation gas wave refrigerating machine, belonging to the field of gas expansion refrigeration low temperature technology, a pressure gas is jetted to a receiving pipe to generate kinematic waves to dissipate energy, thereby realizing refrigeration, the rotating speed is low and the operation is simple. The mixed containing cavity heat dissipation gas wave refrigerating machine is mainly composed of a machine body, a rotating jet flow distributor, a short receiving pipe, a receiving pipe cylinder, a mixed containing cavity and a heat exchanging unit and is characterized in that the end of the short receiving pipe is opened and is communicated with the mixed containing cavity, the heat exchanging unit is arranged in the mixed containing cavity, and the energy of a compression wave or a shock wave, which is transmitted to the mixed containing cavity from the short receiving pipe, is adsorbed by the heat exchanging unit. The heat dissipation and buffer structure that the mixed containing cavity is spliced by the short receiving pipe is adopted in the invention, therefore, the complete machine volume is small, the pipe can not be broken by vibration, the refrigeration efficiency is high, the changing fluctuation is little, the exhaust of refrigeration gas condensate is very convenient, and the transformed energy is easy to be recycled. The mixed containing cavity heat dissipation gas wave refrigerating machine can be widely used in the field of condensation separation of mixed gas, light dydrocarbon recycle in petroleum gas, low temperature dehydration of natural gas, low-temperature gas source supply and the like.

Description

technical field [0001] The invention belongs to the technical field of pressurized gas expansion refrigeration, and in particular relates to a gas refrigeration machine, that is, a common-cavity heat dissipation gas wave refrigerator. Background technique [0002] Expansion refrigeration can obtain a lower low temperature than refrigeration with working fluid circulation. Utilizing the pressure expansion refrigeration of the gas itself has great application value in the fields of oil and gas development and processing. In addition to turbo expanders, heat separators and gas wave refrigerators (Chinese patents 87101903.5, 89213744.4, 90222999.0) etc. also belong to gas expansion refrigeration machines. These refrigerators can work efficiently at lower speeds, avoiding the inconvenience of having to run at high speeds like cryogenic turboexpanders. Existing heat separators and gas wave refrigerators all use pressurized gas to perform unsteady expansion work on the retained g...

Problems solved by technology

The heat of the long tube wall is dissipated in the environment. Although there is no need for additional cooling and heat exchange, the heat cannot be recovered

However, the above-mentioned problems such as large volume, broken tube due to vibration, high average ratio of jet mixing, fluctuation of efficiency, and effusion are limited by this structure, and it is difficult to fundamentally solve them.
