It should be noted that the main steam valve 1 is a common switch valve in the prior art, and has two states of fully open and fully closed.
Referring to fig. 1, in the intake pressure adjusting system of the turboexpander according to the first embodiment of the present invention, when operating, the main steam valve 1 is opened, if the pressure of the high-pressure gas entering the pressure-regulating gas supplementing device 2 is not lower than the design pressure of the inlet of the turboexpander 3, the pressure-regulating gas supplementing device 2 adjusts the pressure of the high-pressure gas to the design pressure through pressure regulation, and then the high-pressure gas enters the first-stage blade of the turboexpander 3 from the pressure-regulating outlet end a to drive the first-stage blade of the turboexpander 3 to generate power, so that the turboexpander 3 operates at the rated power; if the pressure regulating function of the pressure regulating and air supplementing device 2 is fully opened, the gas pressure at the inlet end of the pressure regulating and air supplementing device 2 is still lower than the design pressure at the inlet of the turbine expander 3, the air supplementing outlet end b is correspondingly opened, after the high-pressure gas enters the pressure regulating and air supplementing device 2 from the main steam valve 1, a part of the high-pressure gas enters the first-stage blade of the turbine expander 3 from the pressure regulating outlet end a of the pressure regulating and air supplementing device 2 and drives the first-stage blade of the turbine expander 3 to generate electricity, the other part of the high-pressure gas enters the middle-stage blade of the turbine expander 3 from the air supplementing outlet end b of the pressure regulating and air supplementing device 2 and drives the middle-stage blade of the turbine expander 3 to generate electricity, so that the turbine expander 3 can work under the rated power, and compared with the throttling regulation of the existing full-cycle air inlet regulating valve, the design pressure at the inlet of the turbine expander 3 in the air inlet pressure regulating system of the first embodiment does not need to be the lowest design pressure when the turbine expander 3 works under the rated power The pressure and the throttling loss are small, the utilization rate of the high-pressure gas is obviously higher, and the increase of the power generation capacity of the turboexpander 3 is facilitated.
Preferably, referring to fig. 1, the pressure-regulating air-supplementing device 2 includes a regulating valve 21 and an air-supplementing valve 22, an outlet of the regulating valve 21 is a pressure-regulating outlet a communicated with an inlet of the first stage blade of the turbo expander 3, an outlet of the air-supplementing valve 22 is an air-supplementing outlet b communicated with an inlet of the middle stage blade of the turbo expander 3, and an outlet of the main steam valve 1 is communicated with an inlet of the regulating valve 21 and an inlet of the air-supplementing valve 22. Compared with the prior regulating-stage regulation combining the regulating valve and the nozzle gas distribution structure, the inlet pressure regulating system of the turboexpander in the first embodiment has the advantages of fewer regulating valves 21, relatively simple structure and easy control.
It should be noted that the way of adjusting the first stage blade of the turboexpander by the adjusting valve 21 in the first embodiment is the circumferential intake adjusting valve throttling adjustment in the prior art; the regulating valve 21 and the air compensating valve 22 are both in the prior art, and the regulating valve 21 can control the pressure of the pipeline by regulating the opening degree of a valve port of the regulating valve; the air compensating valve 22 can compensate the air by adjusting the opening of the valve port of the air compensating valve, thereby improving the discharging efficiency of the pipeline.

As can be seen from fig. 3, the smaller the intake air amount at the same power and the same intake pressure indicates that the higher the utilization rate of the high-pressure gas in the turbo expander, the smaller the intake air amount in a longer intake pressure variation range of the intake pressure adjustment C of the turbo expander using the intake pressure adjustment system of the turbo expander of the first embodiment is, the smaller the intake air amount in a longer intake pressure variation range is than the intake air amount in the full-cycle intake regulating valve throttle adjustment a and the regulating-stage adjustment B in which the regulating valve and the nozzle distribution structure are combined, that is, the higher the utilization rate of the high-pressure gas in the turbo expander using the intake pressure adjustment C of the turbo expander of the first embodiment is, in this intake pressure variation range, the higher the utilization rate of the high-pressure gas in the turbo expander using the full-cycle intake regulating valve throttle adjustment a and the regulating-stage adjustment B in which the regulating valve and the nozzle distribution structure are combined.

When the adjusting steam supply device 2 fails, the normal operation of the inlet pressure adjusting system of the turboexpander in the third embodiment can be realized by maintaining and replacing the adjusting and steam supply combined valve, and compared with the adjusting steam supply device consisting of a plurality of different parts, the efficiency of maintaining and replacing the adjusting steam supply device 2 in the third embodiment is obviously higher.
It should be noted that the adjustment valve 21 of the third embodiment adjusts the first stage blades of the turboexpander in the manner of the full-cycle intake adjustment valve throttle adjustment of the related art.
