Detailed description of the invention
A kind of intelligent vacuum absorbs minute-pressure steam thermal energy advanced recycling system, and as Fig. 1, this system comprises vacuum and steam absorber 1, liquid collecting tank 2, heat-exchanger pump 3, intelligent controlling device 4 and oxygen-eliminating device 5.Vacuum and steam absorber is provided with steam inlet 11, cooling water inlet 12 and outlet 13, and cooling water inlet 12 is connected with cold water pipe 6, and steam inlet 11 is connected with vapour source 7, and vapour source can be determine row's flash vessel or boiler feed.Vacuum and steam absorber can be arranged on liquid collecting tank top or near, the outlet of vacuum and steam absorber is connected with the upper end of liquid collecting tank, and oxygen-eliminating device is arranged in liquid collecting tank.Liquid collecting tank is provided with hot water outlet 21 and on-condensible gas floss hole 22, and on-condensible gas floss hole is arranged on liquid collecting tank upper end, and hot water outlet is arranged on liquid collecting tank lower end and is connected with heating plant 8 by heat-exchanger pump; Heat-exchanger pump is arranged on below liquid collecting tank.Intelligent controlling device is connected with heat-exchanger pump, and intelligent controlling device can be arranged on liquid collecting tank side.
Intelligent controlling device comprises liquid level sensor, temperature sensor, pressure sensor and control valve, and liquid level sensor is arranged in liquid collecting tank, and temperature sensor and pressure sensor are arranged in vacuum and steam absorber, and control valve is arranged on the exit of heat-exchanger pump.When water level is lower than the setting of control low water level, heat-exchanger pump stops automatically; When heat-exchanger pump autoboot after water level rezime, VFC is run.When there is a large amount of draining in the short time, liquid level rises rapidly, and heat-exchanger pump rapid translating is power frequency operation.When liquid collecting tank water level rises, heat-exchanger pump outlet pressure rises, and illustrate into surely arranging the flash vessel water yield and increase, at this moment system opens large valve, otherwise closes minor valve.
When the cold water of certain pressure enters in vacuum and steam absorber through vacuum and steam absorber cooling water inlet, transform through pressure and velocity energy, when vapor (steam) temperature reduces, produce vacuum, the minute-pressure of the steam inlet from vacuum and steam absorber, low-pressure steam are sucked vacuum and steam absorber, carry out direct contact type with cold water to mix, instant steam is condensed into water, and cold water transient heating is to the temperature needed.Hot water through extraordinary runner, then transforms raising certain pressure automatically, is transported to liquid collecting tank.After miniature oxygen-eliminating device being separated on-condensible gas above liquid collecting tank, hot water gravity flow enters liquid collecting tank bottom, and being pressurizeed by heat-exchanger pump outputs to heating plant.
As shown in Figure 2, for the present invention is in the application of the application example of boiler of power plant deaerator exhaust energy recovery, the minute-pressure steam discharged from boiler feed 7 and deaerator feedwater, after the present invention, steam thermal energy exports with the hot water outlet 9 of the form of hot water by heat-exchanger pump, is fed to heating plant.
Structure of the present invention is simple, easy for installation, nucleus equipment movement-less part, the task of almost not maintaining, long service life, security of system is good, does not change original production technology, bring very large economic benefit to user, also reduce environmental thermal pollution, energy-conserving and environment-protective simultaneously.
