It receives in pneumatic ball valve inflow exhaust gas recycling can, changes the previous mode that directly compressor gas is discharged, effectively recycle
Gas in compressor, and do not need manual operation；
2, by the way that the air inlet of air inlet buffer is connected to the gas outlet of waste gas recovery tank, when compressor shutdown, PLC is first
First control air inlet ball valve is closed with pneumatic ball valve is recycled, and controls the unlatching of off-load pneumatic ball valve, is first vented air inlet buffer and is given up
The gas of gas recycling can reduces the pressure in off-gas buffer tank, when reaching the preset lower limit of second pressure transmitter, PLC control
Off-load pneumatic ball valve processed is closed, and is controlled recycling pneumatic ball valve and opened, and starts to recycle the gas in compressor, this mode can
Gas in compressor is excluded completely, when avoiding next compressor start, starting load is excessively high, opens the situation hair of machine difficulty
It is raw；
3, when compressor is again started up, off-load pneumatic ball valve is opened, first with the gas in waste gas recovery tank, when the
When one pressure transmitter detects that the air pressure of waste gas recovery tank reaches the lower limit value of setting, PLC controls air inlet ball valve and opens, effectively
Ground utilizes the exhaust gas in waste gas recovery tank.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model is integrated in that compressor prizes upper automatic gas recovery system；
Wherein corresponding appended drawing reference are as follows:
1- second pressure transmitter, 2- air inlet buffer, 3- off-load pneumatic ball valve, 4- first pressure transmitter, 5- exhaust gas
Recycling can, 6- safety valve, 7- recycle pneumatic ball valve, 8- skid compressor.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
