As shown in fig. 1, the condenser vacuum pumping system comprises a pumping pipeline 1 with one end connected with the condenser, the other end of the pumping pipeline 1 is sequentially connected with a front heat exchanger 4, an electric butterfly valve 11, a check valve 12, an oil ring vacuum pump 7, a gas-liquid separator 6, an oil-water separator 9 and a working liquid cooling heat exchanger 8, a working liquid outlet of the working liquid cooling heat exchanger 8 is connected with an oil inlet of the oil ring vacuum pump 7 through a stop valve 13, the front heat exchanger 4 is further provided with a front condensate water inlet 2, a front condensate water outlet 3 and a condensate water heat-returning well pipeline 5, the working liquid cooling heat exchanger 8 is further provided with a cooling water inlet 15 and a cooling water outlet 16, and the bottom of the oil-water separator 9 is further provided with an overflow pipe 10.
The oil-water separator 9 is also connected with a drain pipe 17, and a drain valve 14 is arranged on the drain pipe 17.
The quantity of the electric butterfly valves 11, the check valves 12, the oil ring vacuum pump 7 and the gas-liquid separators 6 which are connected in sequence is at least two, the inlet of each electric butterfly valve 11 is connected with the front heat exchanger 4, and the outlet of each gas-liquid separator 6 is connected with the oil-water separator 9.
The working fluid in the oil ring vacuum pump 7 adopts turbine lubricating oil. In this example, No. 46 turbine lubricating oil was used.
This system is at the during operation, and under the effect of oil ring vacuum pump 7, the exhaust gas in the gas condenser passes through aspiration line 1 and gets into preceding heat exchanger 4, and cooling water gets into preceding heat exchanger 4 from leading condensate water import 2, behind the vapor condensation in the exhaust gas, discharges from leading condensate water export 3, and the condensate water that condenses gets into the heat well of gas condenser lower part through the condensate water heat recovery well pipeline 5 of preceding heat exchanger 4 bottom and is collected. After leaving the front heat exchanger 4, the exhaust gas enters the oil ring vacuum pump 7 through an electric butterfly valve 11 and a check valve 12.
