Description
Technical field
The present invention relates to heat power engineerings, more particularly to a kind of flash vessel.
Background technique
Soda flash evaporator is the equipment for carrying out heat recovery and utilization to high-temperature condensation water or industrial waste water.
Secondary steam in flash vessel from condensed moisture from rear, in low-pressure steam heating system.It is widely used in smelting
The fields such as gold, petrochemical industry, chemical industry, light industry, papermaking, food, wine brewing, beverage, pharmacy.
Enter multistage steam water flash vessel using industrial waste water, the multiply of available different pressures different temperatures, which flashes, steams
Vapour can be used at present in steel, chemical company, being utilized building heating extensively.
China is the big country of steel production, and the annual output of steel accounts for the 40% of Gross World Product.Either steel-making or refining
Iron will generate a large amount of clinker.Clinker is generation of accompanying with steel, it is the byproduct of smelting iron and steel.
In Ferrous Metallurgy furnace, 1400-1500 DEG C of high temperature furnace slag is generated, enters flushing cinder after cinder notch flows out, then through slag runner
When chute, with certain water, hydraulic pressure and the chute gradient, make water and slag stream at certain angle of cut, slag is burst by cold shock
At the qualified grain slag of certain particle size.After pulp water separation, clinker is used as construction material；The flushing cinder of heat exchange is carried out with high temperature furnace slag
Water, into flushing cinder pond.Flushing cinder pond usually takes up an area thousands of square metres, and hot vapour is emptied above flushing cinder pond, and flushing cinder coolant-temperature gage is normal
Year is maintained at 60-80 DEG C, is a huge potential thermal energy energy, says the thermal energy using washing slag water, and winter is residential block confession
It is warm, not only a large amount of fuel can be saved for country, but also reduce carbon emission, protect environment.
Steel mill's blast furnace 1 ton of pig iron of every smelting, the heat that clinker loses account for total amount of heat income in 0.81GJ~0.87GJ
6.61%~7.5%, signature coal is the heat that 27.77kg~29.78kg burning is released, with the calculating of slag ratio 0.44, slag damage per ton
The heat of mistake is about the heat that 63.9kg mark coal completely burned is released.
Currently, blast furnace slag quenching water waste heat recycles, and having been used to heating aspect mainly has Shoudu Iron and Steel Co, Ji steel, Xuan Gang, Anshan iron and steel plant, sheet
Steel, Laigang, An Gangdeng enterprise.
Enter multistage steam water flash vessel using industrial waste water, obtain the multiply flash-off steam of different pressures different temperatures,
It when for building heating, has a problem that: when industrial waste heat coolant-temperature gage is relatively low, flashing the multiply of the different temperatures of generation
In flash-off steam, heating demand is not achieved in temperature lower one or two bursts of vapor (steam) temperatures, can only discard, or improve flash distillation most
Whole waste discharge temperature, reduces recycling total amount of heat.
Summary of the invention
In order to rationally utilize industrial waste water heat, more useful steam are obtained, the present invention provides a kind of flash vessel.
Its structure includes: a kind of flash vessel, its structure includes: water inlet, upper cover, cylinder, the first drip water plate,
One flash chamber, the first steam outlet pipe, the second drip water plate, the second flash chamber, the second steam outlet pipe, third drip water plate, third flash chamber,
Three steam outlet pipes, lower head, water outlet；
Industrial waste water enters from the top water inlet of flash vessel, generates by the first drip water plate into the first flash chamber
Flash-off steam, pass through the first steam outlet pipe flow out；Remaining spent hot water is flashed, enters the second flash distillation by the second drip water plate downwards
Room, the flash-off steam of generation are flowed out by the second steam outlet pipe；Remaining spent hot water is flashed, third drip water plate is passed downwardly through, into the
Three flash chambers, the flash-off steam of generation are flowed out by third steam outlet pipe.
The structure of flash vessel further includes a steam jet ejector, its driving steam inlet connects out steam pressure higher
One steam outlet pipe, its suction steam ports connect out the lower third steam outlet pipe of steam pressure, it provides the steam of middle pressure.
Detailed description of the invention
Fig. 1 is a kind of flash vessel embodiment overall pattern of the present invention.
Specific embodiment
With reference to the accompanying drawings and examples, present invention is further described in detail.
Fig. 1 gives a kind of flash vessel embodiment overall pattern of the present invention.
A kind of flash vessel embodiment of the present invention, its overall 100 structure includes: water inlet 107, upper cover 101, water drenching
Plate 108, the first flash chamber 102, cylinder 109, the second flash chamber 103, third flash chamber 104, lower head 105, water outlet 106,
First steam outlet pipe 210, the second steam outlet pipe 220, third steam outlet pipe 230, steam jet ejector 200, injector outlet 240.
A kind of flash vessel embodiment of the present invention is a three stages of flashing device, erects and places, its specific work process is
Industrial waste water enters from the top water inlet 107 of flash vessel, by the sky between upper cover 101 and drip water plate 108
Between, then by drip water plate 108, into the first flash chamber 102.
First flash chamber 102 generates the flash-off steam of higher temperature and elevated pressures, goes out vapour by first on cylinder 109
Pipe 210 enters in steam jet ejector 200 as driving steam, and high speed is sprayed, and makes to generate low-voltage space in steam jet ejector 200.
The spent hot water of remaining lower temperature is flashed by the first flash chamber 102, enters the by the second drip water plate downwards
Two flash chambers 103 generate the flash-off steam of moderate temperature in the second flash chamber 103, are discharged by the second steam outlet pipe 220.
The spent hot water of remaining low temperature is flashed in the second flash chamber 103, third drip water plate is passed downwardly through, into third flash chamber
104, the flash-off steam of lower temperature and lower pressure is generated, the low pressure of steam jet ejector 200 is entered by third steam outlet pipe 230
Space after it is mixed with driving steam, passes through the externally discharge of injector outlet 240.
Remaining low temperature waste heat water after three stages of flashing is discharged by lower head 105 by water outlet 106.
A kind of flash vessel embodiment of the present invention, the difference of it and traditional three stages of flashing vapour have been that its more a steam sprays
Device 200.
The effect of steam jet ejector is: the higher temperature and higher pressure that it utilizes the first flash chamber 102 of flash vessel to generate
The steam of power is as driving steam, the flash-off steam of lower temperature and lower pressure that injection third flash chamber 104 generates, the two
After mixing boosting, reach moderate temperature and middle pressure, flowed out from the outlet of steam jet ejector 200 240, supplies heat user, from
And the flash-off steam for the lower temperature and lower pressure for generating third flash chamber 104 is utilized.
