Abstract

Provided is a phase change acting device of high-pressure mixed dielectric gas. The phase change acting device enables the high-pressure mixed dielectric gas to be directly liquefied in the expansion acting process, so that phase change of the gas happens, the maximum volume work is output, and a low-temperature heat source can be automatically generated to maintain the work state of an acting system.

Description

The phase transformation acting device of high pressure mixing dielectric gas

Technical field

The present invention relates to a kind of acting device of dielectric gas, relate in particular to the acting device that a kind of high pressure mixing dielectric gas undergoes phase transition by doing work.

Background technique

Using in gas medium circular work system, be that gas is done volumetric work, and the volumetric work of gas maximum is the phase transformation acting of gas, and existing gas circulation working system is as Rankine cycle, the dielectric gas that all can not make to do work such as Carnot's cycle undergoes phase transition by doing work, want to make gas to undergo phase transition and all must consume external work to gas compression or reduce temperature, as the patent of invention of application number 201110279848.9 " across critical low-temperature air energy generating device ", adopted equally compressor to compress and make its liquefaction dielectric gas, hot merit low conversion rate so not only, and need consume a large amount of external works, also need two thermals source of height simultaneously.

Summary of the invention

In order to overcome the deficiency that in existing gas medium circular work system, dielectric gas can not undergo phase transition by acting direct liquefaction, the invention provides a kind of phase transformation acting device of high pressure mixing dielectric gas, this device can make dielectric gas direct liquefaction and undergo phase transition in expansion acting process, export maximum volumetric work, and can automatically produce the working state that a low-temperature heat source maintains working system.

The present invention addresses the above problem adopted technological scheme to be: the phase transformation acting device of high pressure mixing dielectric gas mainly comprises acting cylinder or decompressor, high pressure mixing dielectric gas, solenoid valve and connecting pipeline.The piston of acting cylinder from left to right or from right to left moves once, and high pressure mixing dielectric gas is double acting in cylinder.High pressure mixing dielectric gas is the low boiling mixed medium gas composition by two or more different critical temperature, acting first will make while starting the to do work delivery outlet of cylinder is manufactured an environment under low pressure, the entrance of acting cylinder is by the displacement distance of the piston of electromagnetic valve acting cylinder, export a certain amount of shaft work, then air inlet electromagnetic valve is closed, exhaust solenoid valve keeps conducting, piston continues to move and make dielectric gas do adiabatic expansion acting by original direction, owing to being low boiling mixed medium gas, and mix by a certain percentage, in adiabatic expansion acting process, the slightly high dielectric gas of critical temperature starts liquefaction, make mixed medium gas become gas liquid mixture, carrying out along with adiabatic expansion acting process, the temperature of gas-liquid mixed media gas is dropped to and approach liquefaction point, piston movement completes an acting process during to terminal, then control solenoid valve upset and make to do work cylinder while oppositely doing work, the dielectric gas of the gas-liquid mixed of this low-temp low-pressure is discharged, so reciprocal acting output shaft work.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention will be further described

Fig. 1 is the workflow schematic diagram of one of preferred embodiment of the present invention.

Embodiment

As shown in Figure 1 in embodiment, (1) be pressurized gas end, (2) be acting cylinder, (3) be low-temp low-pressure end, (4, 5, 6, 7) be solenoid valve, (k1, k2, k3, k4) be the position of piston in acting process of acting cylinder, when acting starts, solenoid valve (4, 7) open, (5, 6) cut-off, piston moves to k2 from k1, dielectric gas constantly enters cylinder and promotes piston acting, piston is solenoid valve 4 cut-offs during to k2, solenoid valve (7) continues conducting, gas starts to do adiabatic expansion acting, temperature and pressure starts to decline, piston is from k2 to k3, in mixed medium gas, the slightly high dielectric gas of critical temperature completes liquefaction, piston continues from k3 to the slightly low dielectric gas of k4 critical temperature further to drop to minimum by do work make the to do work temperature and pressure of the gas-liquid mixed media gas in cylinder of adiabatic expansion, solenoid valve (7) cut-off, now complete an acting process, during piston reverses direction motion, enter next acting process, solenoid valve (5, 6) conducting, (4, 7) cut-off, so repeatedly carry out.
