The traditional equipment which can realize injection pressurization by utilizing the pressure of high-pressure gas comprises an expander-compressor unit, a turbocharger, a static injector and the like. The expansion machine-compressor unit, the turbocharger and other equipment have complex structures, high processing and maintenance cost and poor liquid carrying operation capacity, and the static ejector is static equipment with a simple structure, but has low efficiency and is easy to cause a large amount of pressure energy waste.

However, the existing air wave superchargers such as the patent axial flow jet air wave supercharger CN201220115597.0 and the radial flow jet air wave supercharger CN201210081102.1 have the problems of low refractive index and low efficiency under the working condition of large expansion ratio.
Disclosure of Invention
In order to solve the above problems, the present invention provides a condensation separation type gas wave supercharging device and a working method thereof. Aiming at the problems in the prior art, under the working condition of large expansion ratio, firstly, the cold source is manufactured by utilizing high-pressure gas expansion, part of compression work generated by the expansion is recovered to obtain high-pressure return gas for injection, after injection pressurization is completed on the injected low-pressure gas, the cold source generated by the high-pressure gas expansion is utilized to condense and dehumidify the medium-pressure produced gas, the final medium-pressure dry gas is obtained, and the high-efficiency utilization of the energy of the high-pressure gas is realized.
The technical scheme adopted by the invention is as follows:
under the drive of the transmission shaft, the wave rotor rotates between the base and the medium-pressure supporting plate, the lower end of each oscillating tube is sequentially communicated with the high-pressure nozzle, and high-pressure gas is injected into the oscillating tubes to heat and boost the original gas in the tubes into high-temperature gas; when the upper end of the oscillating pipe is screwed to be communicated with the high-temperature gas outlet nozzle, high-temperature gas is sprayed into the high-temperature gas outlet cavity through the opening at the upper end of the oscillating pipe, the high-temperature nozzle adjusting plate and the high-temperature gas outlet nozzle in sequence; after the high-temperature gas flows out of the high-temperature gas outlet cavity, the pressure of the high-temperature gas can be adjusted through the high-temperature gas outlet adjusting valve; the high-temperature outlet air flows through the regulating valve, enters the heat recoverer to release heat energy, and then enters the high-pressure air return cavity to become high-pressure air return; when the wave rotor continues to rotate and the lower end of the oscillation tube is communicated with the low-temperature gas outlet nozzle, low-temperature gas which is formed by expanding and working conversion of high-pressure gas is discharged into the low-temperature gas outlet cavity through the low-temperature gas outlet nozzle; the low-temperature outlet gas enters the gas heat exchanger under the driving of the driving fan, enters the low-pressure gas return cavity after releasing cold quantity, and then enters the oscillating pipe to be used as low-pressure return gas to push the low-temperature gas to be discharged; the wave rotor continues to rotate, the lower end of the oscillating tube is communicated with the high-pressure air return nozzle, and at the moment, high-pressure return air in the high-pressure air return cavity is injected into the oscillating tube to compress gas in the tube, so that the gas in the tube is boosted to be medium-pressure gas production; when the oscillating pipe rotates to be communicated with the low-pressure air inlet nozzle, low-pressure air inlet in the low-pressure air inlet cavity is sucked into the oscillating pipe by a low-pressure area formed after high-pressure gas in the oscillating pipe expands, so that the low-pressure air inlet is injected; when the oscillating pipe continues to rotate to be communicated with the medium-pressure gas generating nozzle, the medium-pressure gas enters the medium-pressure gas generating cavity through the medium-pressure gas generating nozzle and the flow guide channel; the medium-pressure gas flows out of the medium-pressure gas-generating cavity and then enters the gas heat exchanger, the energy released by the low-temperature gas outlet is utilized to realize condensation, and when the medium-pressure gas flows through the gas-liquid separator, the medium-pressure gas is dehumidified, so that the whole condensation separation type gas wave pressurization process is completed.
When the pressure of a high-pressure gas source for injecting pressurized low-pressure gas is far greater than that of low-pressure injected gas, the pressure of the high-pressure gas source for injecting pressurized low-pressure gas can be reduced by the condensing gas wave pressurization method, and the specific pressure value can be controlled by a high-temperature gas outlet regulating valve, so that the injection pressurization process can be carried out at an expansion ratio with high efficiency. The condensing type gas wave supercharging method provided by the invention can overcome the defect that the performance of the traditional gas wave supercharger is limited under a large expansion ratio, ensures that the equipment has a better injection supercharging effect under a large expansion ratio, and improves the application range and the isentropic working efficiency of the equipment. The condensation gas wave pressurization method provided by the invention can also avoid the waste of high-pressure gas energy, the energy output in the high-pressure gas expansion process is effectively recycled for injecting low-pressure gas, and the cold energy generated in the expansion process is also utilized for condensation and dehumidification of the final product of equipment.
The device comprises a core component wave rotor driven by a transmission shaft, wherein the rotor consists of oscillating pipes with two open ends which are uniformly distributed along the circumferential direction, the oscillating pipes are completely different and are not communicated with each other, and the axial direction of each oscillating pipe is parallel to the axial direction of the rotor. The medium-pressure gas generating cavity, the medium-pressure and high-temperature exhaust cavities and the high-temperature exhaust nozzle are positioned at one end of the oscillating pipe; the high-pressure air inlet cavity and the high-pressure air inlet nozzle, the low-temperature air outlet cavity and the low-temperature air outlet nozzle, the high-pressure air return cavity and the high-pressure air return nozzle, and the low-pressure air inlet cavity and the low-pressure air inlet nozzle are all positioned at the other end of the oscillating pipe; the cavity between the outer wall surface of the rotor and the shell is the low-pressure air return cavity. The transmission shaft drives the rotor to rotate, so that the oscillating pipe is sequentially communicated with the nozzles, and the pressure and temperature gases are discharged into corresponding air cavities.
In order to ensure that two ends of the oscillating tube are communicated with different nozzles in sequence at a certain time interval, certain deflection angles among the nozzles are required to be ensured; in the invention, the deflection angle adjusting plate, the middle-pressure side bearing cover and the middle-pressure support plate are connected into a whole through the bolt, so that deflection angles between three nozzles such as a high-temperature gas outlet nozzle on the middle-pressure support plate and four fixed-position nozzles such as a high-pressure gas inlet nozzle arranged on the base can be adjusted by rotating the deflection angle adjusting plate to a proper angle; after the deflection angle is adjusted, a locking screw penetrating through the angle fixing plate is inserted between two teeth of the tooth type indexing disc which are right opposite to the through hole of the angle fixing plate, and then the fixation of the deflection angle can be realized.
The invention has the beneficial effects that: under the working condition of large expansion ratio, the injection rate and the isentropic efficiency of the traditional gas wave supercharger are lower, if the high-pressure inlet pressure is reduced by means of throttling, pressure reduction and the like, the injection pressurization process is carried out after the expansion ratio is reduced, although the injection effect can be improved, the high-pressure gas energy utilization rate is low, the pressure energy of the high-pressure gas is wasted, and the refrigeration efficiency is low; the invention utilizes the high-pressure gas expansion to produce the cold source, has high refrigeration efficiency, simultaneously recovers the output compression function to obtain the high-pressure return gas with moderate pressure to inject and pressurize the low-pressure gas, and utilizes the obtained low-temperature cold source to condense and dehumidify the medium-pressure gas, thereby realizing the full utilization of the excess high-pressure gas pressure under the working condition of large expansion ratio, ensuring higher index and obtaining the dehumidified and purified dry and medium-pressure gas; the invention realizes expansion refrigeration and injection pressurization by using one wave rotor, reduces equipment processing investment and is convenient to transport and assemble.
