Problems solved by technology

The efficiency of these refrigerators is relatively high, but due to the complex structure, there are many rotating parts, in order to prevent the leakage of gas outside and the leakage of different internal pressure areas, a rotating seal is required, which will greatly reduce the pressure resistance of the machine

Embodiment approach

[0033] A typical implementation of the feedback type oscillating jet refrigerator of the present invention is as follows:

[0034]The feedback type oscillating jet refrigerator is mainly composed of the adjusting mechanism 1, the upper cover 2, the outlet cavity 3, the cold air outlet 4, the body 5, the inlet pipe 6, the inlet cavity 7, the jet nozzle flow channel 8, the upper cover opening 9, and the branch flow The channel 10, the pipe joint 11, the receiving tube 12, the receiving tube inlet 13 and the compression wave feedback channel 14 are composed. It is characterized in that the whole machine is completely static and adopts the structure of the feedback type oscillating jet generator and the receiving tube 12. The length of the middle section of the compression wave feedback channel 14 is changed by the adjustment mechanism 1, thereby changing the wall switching frequency of the jet. The compression wave feedback channel 14 is processed into two sections on the body, and t...

Abstract

The invention provides a reaction-type oscillation jet flow refrigerating machine and belongs to the gas pressure energy expansion refrigeration field. The whole machine of the invention is totally static, and adopts the combined structure of a reaction-type oscillation fluidic generator and an adopter, the actuation to the jet flow is realized by the compression wave reaction in order to generate the oscillatory wall-attachment jet, unsteady gas expansion refrigeration is realized by the cooperating work of a flow channel component, a regulating mechanism is coupled in a compression wave reaction channel, the switching frequency of the jet wall-attachment oscillation is changed via regulating gas capacity to adapt to different operating conditions, thereby obtaining the highest operating efficiency. The invention has no moving member or dynamic sealing, thereby being particularly suitable for high pressure situations, such as high pressure natural gas deep freezing dehydration, recovering heavy component from high pressure gas mixture and so on. The variable gas capacity frequency modulation self-oscillation jet flow refrigerating machine with higher refrigerating efficiency and lower refrigerating temperature than that of throttling decompression can run with liquid, thereby providing an efficient method and a device for efficient utilization of pressure energy in the combination gas stratum.

Description

Technical field [0001] The feedback type oscillating jet refrigerating machine of the present invention is a gas refrigeration machine, belonging to the technical field of pressure gas jet engineering and gas expansion refrigeration. Background technique [0002] Expansion refrigeration can achieve a lower temperature than the use of working fluid cycle refrigeration. Utilizing the pressure of the gas itself to expand and refrigerate, it has great application value in the fields of oil and gas development and processing. In addition to turbo expanders, there are also expansion refrigeration machinery such as gas wave refrigerators and thermal separators (Chinese patents 87101903.5, 89213744.4, 90222999.0). The latter two are unsteady expansion and refrigeration, which rely on motors or use gas injection reaction forces to drive The gas distributor spins and jets the medium gas to the closed receiving tube at each end in the circumferential direction at a certain rotation speed, a...
