Description
(1) technical field
The utility model relates to technical field of steel production, in particular to a kind of steel blast furnace slag flushing steam white cigarette eliminate and
Residual neat recovering system.
(2) background technique
In recent years, with economic rapid development, the high humidity discharged in the industry productions such as steel, chemical industry, electric power, food is useless
Gas is growing day by day, not only wastes a large amount of thermal energy and water resource, while arranging after environment, generates greatly after mixing is contacted with cold dry air
" white cigarette " of amount, the particulate matters such as small liquid pearl and sulfide, nitrogen oxides and the dust of water vapour condensation combine easy formation haze,
Seriously affect surrounding enviroment visibility and the physical and mental health of resident.
Currently, there are mainly two types of the methods of elimination white cigarette, first is that the temperature of exhaust gas is improved, to improve it containing wet ability；Two
It is the water vapour in condensation exhaust gas.However heat change method is mostly used using the method for condensation vapor at present, so
And it is difficult to realize the recycling of vapor recycled with waste heat.
(3) utility model content
The utility model in order to make up for the deficiencies of the prior art, provide a kind of steel blast furnace slag flushing steam white cigarette eliminate and
Residual neat recovering system.
The utility model is achieved by the following technical solution:
A kind of steel blast furnace slag flushing steam white cigarette is eliminated and residual neat recovering system, is characterized in that: including being fixed on steel height
The gas gathering mask of clinker ditch open upper end, the gas gathering mask are connected with the n grade being sequentially connected in series by pipeline and disappeared vapour tower, and adjacent two
The vapour tower that disappears is connected by air inlet pipe；Each vapour tower that disappears includes the internal spray equipment being equipped with, and the spray equipment connects
It is connected to water supply pipe and circulation pipe；The circulation pipe other end is connected with triple valve, and triple valve passes through pipeline and the vapour tower bottom that disappears respectively
Portion and heat exchanger heat exchange outlet connection；The vapour tower bottom end that disappears is connect by pipeline with heat exchanger heat exchange import, the heat exchanger
It further include cooling medium inlet and waste heat source outlet；The vapour tower bottom end that disappears is also connected with return pipe, the return pipe other end and steel
The connection of iron blast furnace slag runner；Blower is connected with by pipeline positioned at vapour tower is disappeared described in terminal primary；The fan outlet passes through
Pipeline is connect with steel blast furnace residue channel.
Further, the water supply pipe, circulation pipe are equipped with valve on return pipe；The circulation pipe is equipped with water circulating pump.
Further, the vapour tower that disappears is spray column.
Further, the n is 1-4.
Further, for the vapour tower bottom that disappears equipped with sewage pipe, sewage pipe is equipped with blowdown valve.
When the utility model is used, a large amount of white cigarettes generated in slag runner are since the effect of blower enters in the vapour tower that disappears, initially
Stage can add water to spray steam white cigarette spray equipment by water supply pipe；After steam white cigarette is cooled, vapor
It is condensed into water to be stored in inside the vapour tower that disappears, with cooling progress, ponding gradually increases inside the vapour tower that disappears, inside the vapour tower that disappears at this time
Temperature increases when ponding temperature relatively sprays, and ponding replaces temperature, recovery waste heat by heat exchanger inside the vapour tower that will disappear；Through supercooling
Water be back to by water circulating pump and disappear in vapour tower or send to spray equipment for cooling down vapor, realization recycles, and can
Slag runner bath is used for ponding inside the vapour tower that will disappear；Gas after the vapour tower that disappears, which is sent by blower to slag runner, to be realized at closed loop
Reason.
The beneficial effects of the utility model are: the utility model can effectively remove steam white cigarette, and by white to steam
The cooling recycling recycled with waste heat for realizing recycle-water of cigarette, and the gas after the vapour tower that disappears can also recycle,
Realize closed-loop process.
(4) Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model；
In figure, 1 slag runner, 2 gas gathering masks, 3 disappear vapour tower, 4 spray equipments, 5 water supply pipes, 6 circulation pipes, 7 return pipes, 8 blowers, and 9
Valve, 10 water circulating pumps, 11 air inlet pipe, 12 triple valves, 13 heat exchangers.
(5) specific embodiment
Attached drawing is a kind of specific embodiment of the utility model.The embodiment includes being fixed on the opening of steel blast furnace residue channel 1
The gas gathering mask 2 of upper end, the gas gathering mask 2 are connected with the n grade being sequentially connected in series by pipeline and disappeared vapour tower 3, disappeared described in adjacent two
Vapour tower 3 is connected by air inlet pipe 11；
Each vapour tower 3 that disappears includes the internal spray equipment 4 being equipped with, and the spray equipment is connected with water supply pipe 5 and follows
Endless tube 6；6 other end of circulation pipe is connected with triple valve 12, and triple valve 12 passes through pipeline and disappear 3 bottom of vapour tower and heat exchange respectively
The heat exchange of device 13 outlet connection；Triple valve 12 and the pipeline of the heat exchange of heat exchanger 13 outlet connection are equipped with water circulating pump 10；It is described to disappear
3 bottom end of vapour tower is connect by pipeline with the heat exchange import of heat exchanger 13, and the heat exchanger 13 further includes cooling medium inlet and waste heat
Source outlet；After the cold water cooling steam to disappear in vapour tower 3, partial recirculation returns the vapour tower 3 that disappears, and continues cooling steam；
3 bottom end of vapour tower that disappears is also connected with return pipe 7, and 7 other end of return pipe is connect with steel blast furnace residue channel 1；Disappear vapour
After cold water cooling steam in tower 3, it is partially guided to slag runner 1, the supplement for washing slag water；
Blower 8 is connected with by pipeline positioned at vapour tower 3 is disappeared described in terminal primary；8 air outlet of blower passes through pipeline
It is connect with steel blast furnace residue channel 1.Demister is equipped at 3 gas outlet of vapour tower that disappears described in terminal primary.
Further, the water supply pipe 5, circulation pipe 6 are equipped with valve 9 on return pipe 7；The circulation pipe 6 is equipped with circulation
Water pump 10.
Further, the vapour tower 3 that disappears is spray column.
Further, the n is 1-4.
Further, equipped with sewage pipe, sewage pipe is equipped with blowdown valve for 3 bottom of vapour tower that disappears.
Cold supply system can also be added in this system, and the cold supply system includes air-cooler, and air-cooler passes through pipeline to the vapour that disappears
Transporting cold wind in tower, for cooling down vapor, the partially liq of the steam transformation in the vapour tower that disappears is recycled for the vapour tower that disappears, with cooling
Steam；The partially liq of steam transformation in vapour tower that disappears flow to slag runner by pipeline, the supplement for washing slag water
When the utility model is used, a large amount of white cigarettes generated in slag runner 1 are since the effect of blower 8 enters in the vapour tower 3 that disappears, just
