Vacuum system having condenser and root vacuum pump set

A vacuum system having an independent inlet condenser set and a root vacuum pump set, comprising:

• the independent inlet condenser set (10) having an inlet end (11) connected to a generator (1) including an air cooling power generator condenser (100);
• the independent inlet condenser set (10) serving for receiving an input vapor inputted from the air cooling power generator condenser (100);
• the input vapor being a mixture of non-condensable air and water steam;
• the water steam capable of being condensed, and the surplus air being outputted;
• a pressure sensor (101) installed on the independent inlet condenser set (10) for detecting a first input pressure of the vapor inputted to the inlet end (11) of the independent inlet condenser set (10);
• the root vacuum pump set (30) including at least one root vacuum pump (40);
• the root vacuum pump set (30) further including an input end (31) and an output end (32);
• the input end (31) being connected to the independent inlet condenser set (10);
• an air outputted from the independent inlet condenser set (10) being inputted to the at least one root vacuum pump (40) for being compressed and the compressed air being outputted from the output end (32) and
• a backing pump (50) connected to the output end (32) of the root vacuum pump set (30) by using an output pipe (33);
• the backing pump (50) serving to receive an air outputted from the root vacuum pump set (30);
• a vapor-liquid separator (95) having an input end (957) which is connected to the backing pump (50);
• a bypass pipe (35) connected between the output end (32) of the root vacuum pump set (30) and the input end (957) of the vapor-liquid separator (95);
• the vapor-liquid separator (95) serving to receive an input air outputted from the backing pump (50) or the bypass pipe (35) and to separate a vapor and a liquid in the input air;
• a control valve (37) installed at the output end (32) of the root vacuum pump set (30) and connected to an input end (331) of the output pipe (33) and an input end (351) of the bypass pipe (35) for opening and closing the output pipe (33) and the bypass pipe (35);
• a central controller (90) connected to the pressure sensor (101), the control valve (37), the heat exchanger (60) and the backing pump (50);
• the central controller (90) serving to receive the first input pressure from the pressure sensor (101) and determine to control the compressed air from the root vacuum pump set (30) to be outputted to the output pipe (33) or the bypass pipe (35) by controlling the control valve (37);
• wherein when the central controller (90) controls the control valve (37) to open the output pipe (33) and close the bypass pipe (35), the backing pump (50) and the heat exchanger (60) are activated by the central controller (90);
• the compressed air from the root vacuum pump set (30) is inputted into the output pipe (33) and passes through the heat exchanger (60) and the backing pump (50) to be inputted to the vapor-liquid separator (95);
• and
• wherein when the central controller (90) controls the control valve (37) to close the output pipe (33) and open the bypass pipe (35), the backing pump (50) and the heat exchanger (60) are deactivated by the central controller (90);
• and the compressed air from the root vacuum pump set (30) is inputted into bypass pipe (35) to pass through the bypass pipe (35) to be directly outputted to the vapor-liquid separator (95).
