The high temperature and high pressure steam that the mixing section (22) of pump (4) sprays with nozzle (21) mixes, by jet pump (4) trunnion section (23),
Diffuser (24), improve mixed vapour pressure, temperature, by compression fluid outlet (25) enter high temperature water- to-water heat exchanger (8), with from
The end recirculated water that end water inlet (16) enters is exchanged heat, and is gone out by end water by end recirculated water after sufficient heat exchange
The mouth of a river (17) is discharged, and high-temperature high-pressure steam is condensed into the flushing cinder in the adjusted valve of condensed water (10) and washing slag water outlet pipe (11)
After water mixing, through washing slag water draining pump (12) discharge system.
6. a kind of washing slag water heating system, it is characterised in that sprayed from cooling steam comprising a kind of negative pressure described in claim 1-5
Penetrate formula heat pump, by blast furnace (27), flushing cinder water filter (28), cistern (29), flushing cinder water-circulating pump (30), switching valve A (31),
Switching valve B (32), washing slag water feed pipe (33), negative pressure cool down steam jet heat pump (34), washing slag water return pipe (35), end certainly
End water circulating pump (36), end feed pipe (37), end system (38), end return pipe (39) composition, during heat supply, switching valve A
(31) close, switching valve B (32) is opened, after washing slag water is by flushing cinder water filter (28) coarse filtration, into cistern (29), then by
It is steam-sprayed from cooling down that flushing cinder water-circulating pump (30) pressurization is delivered to negative pressure through switching valve B (32), washing slag water feed pipe (33)
Heat pump (34) extracts the heat in washing slag water, and cooled washing slag water returns to blast furnace and recycle through washing slag water return pipe (35)；
End recirculated water is exchanged heat by end return pipe (39) into negative pressure from steam jet heat pump (34) is cooled down, end circulating water temperature
After being enhanced, heat supply, recirculated water are carried out to building into end system (38) through end water circulating pump (36), end feed pipe
After temperature reduction, steam jet heat pump (34) cycle heat exchange is cooled down certainly into negative pressure by end return pipe (39).
