The operation principle and advantage of embodiment：
This kind of air feed equipment of large centrifugal air compressor machine, once operation is exactly full carrying row, extra air demand can according to
The gas consumption of gas equipment changes.When this kind of air feed equipment is as upstream air feed equipment 1, upstream gas equipment 10 is made to have more than is needed
Extra air demand accesses air intlet 308 by the outlet for the exhaust-valve 101 being arranged on upstream air feed equipment 1, and admission pressure passes
The admission pressure that sensor 302 is sensed can change with the variation of extra air demand.When air inlet pressure sensor 302 is felt
The admission pressure answered meets the booting pressure condition set, and the intake air temperature satisfaction that temperature sensor 303 is incuded is set
Turn-on temperature condition when, air inlet electromagnetic valve 304 is opened, and host 2 starts, and extra gas supply is successively by 304 He of air inlet electromagnetic valve
Breather check valve 305 enters host 2, mixes pressurization with the lubricating oil in host 2, pneumatic ball valve 306 is closed at this time.
Above-mentioned booting pressure condition is 2.8-3.5bar in this example, and above-mentioned turn-on temperature condition is 0-40 DEG C.
When the on-load pressure condition that the admission pressure satisfaction that air inlet pressure sensor 302 is sensed is set, into temperature
When the intake air temperature that degree sensor 303 is sensed meets the load temperature condition set, control solenoid valve 307 obtains electric beat
It opens, pneumatic ball valve 306 is opened in the pneumatic actuator ventilation of pneumatic ball valve 306.Frequency converter 102 is with air inlet pressure sensor
Difference between the 201 air inlet pressure force value sensed and the air inlet constant pressure value set adjusts permanent magnet frequency conversion motor 101 as foundation
Frequency.When air inlet pressure force value is higher than air inlet constant pressure value, frequency converter 102 improves the frequency of permanent magnet frequency conversion motor 101, works as air inlet
When pressure value is less than air inlet constant pressure value, frequency converter 102 reduces the frequency of permanent magnet frequency conversion motor 101, and admission pressure is made to approach always
Air inlet constant pressure value.On-load pressure is in booting pressure limit, and load temperature is within the scope of turn-on temperature, and on-load pressure is in this example
3bar, load temperature are 0-40 DEG C.Air inlet constant pressure value is in booting pressure limit, and air inlet constant pressure value is 3bar in this example.
Oil gas after pressurization enters barrel of oil and gas 401 and by the oily fine separator in barrel of oil and gas 401 by the gas outlet of host 2
406 are separated into lubricating oil and compressed air.The lubricating oil separated from 401 bottom of barrel of oil and gas flow through oil pump 407 pressurize it is laggard
Enter the cooling of oil gas cooler 502, then is reentered in host 2 through oil strainer 408.The compressed air separated is maintained at oil
In gas bucket 401, when 401 inner air pressure of barrel of oil and gas is more than the closed state maximal pressure force value that pressure maintenance valve 410 is set,
Pressure maintenance valve 410 is opened, and compressed air flows through pressure maintenance valve 410 from the outlet of oily fine separator 406, into oil gas cooler
502 coolings, then be delivered to through venting ball valve 701 and air outlet slit 702 and need what is supplied to need gas equipment 8.Pressure maintenance valve
The closed state maximal pressure force value of 410 settings is more than oily fine separator minimum requirements pressure value and needs needed for gas equipment 8 most
Low supply gas pressure value.
When waste gas reuse air compressor machine meets the unloading halt condition of setting, such as when air inlet pressure sensor 302 is felt
When the admission pressure that should be arrived is less than minimum booting pressure, when in this example for less than 2.8bar, the control power-off of solenoid valve 307 is closed,
The pneumatic actuator of pneumatic ball valve 306, which is died, makes pneumatic ball valve 306 close.304 time-delay closing of air inlet electromagnetic valve.Unload discharging electromagnetic
Valve 601, which is powered, to be opened, and the gas with pressure is discharged into through muffler 602 in air in barrel of oil and gas 401.

When preceding air pressure is greater than the set value, the control solenoid valve power-off is closed, and the pneumatic actuator of the pneumatic ball valve is disconnected
Gas makes the pneumatic ball valve close, the air inlet electromagnetic valve time-delay closing, the main shut-down system.
8. a kind of waste gas reuse air compressor machine as described in claim 1, it is characterised in that：
Further include electric system, the electric system includes permanent magnet frequency conversion motor and frequency converter；
The permanent magnet frequency conversion motor is connected with the host and drives the host, is provided in the permanent magnet frequency conversion motor described
Frequency converter, the frequency of permanent magnet frequency conversion motor described in the Frequency Converter Control；
When admission pressure is higher than setting value, the frequency of permanent magnet frequency conversion motor described in the Frequency Converter Control improves, and works as air inlet pressure
When power is less than setting value, the frequency of permanent magnet frequency conversion motor described in the Frequency Converter Control reduces.
9. a kind of waste gas reuse air compressor machine as described in claim 1, it is characterised in that：
The host is supercharging screw machine, and the host is equipped with host temperature sensor, and the host temperature sensor can
Measure the temperature of the host；
When the temperature of the host is greater than the set value, the control solenoid valve power-off is closed, and the pneumatic of the pneumatic ball valve is held
Row mechanism, which dies, makes the pneumatic ball valve close, the main shut-down system.
10. a kind of waste gas reuse air compressor machine as described in claim 1, it is characterised in that：
The air intake control system further includes accurate filter；
The accurate filter is set on the air intlet to the pipeline between the air inlet pressure sensor.
