Embodiment
Below in conjunction with accompanying drawing and embodiment of the present utility model to the air of the combustion engine of the present utility model further detailed description of cooling system again.
Fig. 1 is the structural representation of original combustion engine system cloud gray model, and Fig. 2 is the structural representation of the air cooling system again that the utility model adds combustion engine.As can be seen from Figure 2, the air cooling system again of combustion engine, comprises combustion engine gas compressor 1, combustion engine turbine 2, exhaust heat boiler 4, is connected with chimney bypass 3 with exhaust heat boiler 4.Wherein exhaust heat boiler 4 arranges high-pressure economizer 5 and high temperature superheater 6, and high temperature superheater 6 provides the high temperature main steam 7 for steam turbine, and exhaust heat boiler end is provided with main chimney 8.
Be communicated with low pressure with combustion engine gas compressor 1 and cool air pipe line 18 and high pressure condenser tube road 19, low pressure cooling air pipe line 18 is connected with low-pressure air cooler 12, high pressure condenser tube road 19 is connected with high-pressure air cooler 11, low-pressure air cooler 12, high-pressure air cooler 11 are connected with exhaust heat boiler 4 and combustion engine turbine 3 respectively, composition circulation loop.
Compared with traditional combustion engine system, improvements of the present utility model are, to connect with high-pressure air cooler 11, low-pressure air cooler 12 a set of cooling water supply system, described cooling water supply system comprises vapour condenser 14, condensate pump 15, deaerating heater 9, feed water pump 10, water tank 17, and described high-pressure air cooler 11, low-pressure air cooler 12, vapour condenser 14, condensate pump 15, deaerating heater 9, feed water pump 10 form a circulation loop successively.Arrange another between vapour condenser 14 and deaerating heater 9 and pass by hot steam circulation loop, the hot vapour source 16 that adds that part flows out from high-pressure air cooler 11, low-pressure air cooler 12 is delivered to deaerating heater 9 through this circulation loop.
As preferred scheme, between vapour condenser 14 and superheated vapor circulation loop, arrange pressure relief valve, when in loop, vapor pressure is excessive, safety valve is opened, and prevents pressure in loop excessive and the dangerous situation of generation, improves Security and the stability of system.
Under combined cycle working state, afterheat boiler system participates in vapor recycle, do not need the cooling water supply system that the utility model increases, under single cycle working state, afterheat boiler system does not work, the utility model increases a set of cooling water supply system for air-cooler provides cooling water, and specific works flow process is as follows:
