Description
Technical field
It is the present invention relates to field of energy recovery, in particular to a kind of suitable for high-temperature molten material is cooling and waste heat recycling
Equipment.
Background technique
Waste heat is the energy not being utilized in using energy source equipment under the conditions of certain economic technology, that is, more
Remaining, the discarded energy.It includes more than high-temp waste gas waste heat, cooling medium waste heat, waste vapour waste water residual heat, high-temperature product and clinker
Heat, chemical reaction waste heat, combustible exhaust gas waste liquid and seven kinds of waste material waste heat and high-pressure fluid overbottom pressure etc..According to investigation, every profession and trade
Waste heat total resources account for about the 17%-67% of its fuel consumption total amount, the residual heat resources of recoverable are about waste heat total resources
60%.Wherein high-temperature product and afterheat of slags, main source have a large amount of blast furnace slag of steel industry, steel slag, ferroalloy productor,
Silicon matallurgical products, Smelting magnesium product etc., calcium carbide product and power industry power plant boiler clinker of chemical industry etc..It is this kind of
Residual heat resources grade is high, but bigger using difficulty.
Lag cooler is the equipment of technology maturation, generally uses the outer chilling roller cartridge type type of cooling, is widely used in cooling power station pot
The solid state heat lime-ash that fire grate removes, the initial temperature of lime-ash are about 1000 DEG C.With the rotation of lag cooler roller, lime-ash is by roller
Portion's spiral blade, which drives, to advance, and heat is taken away by the cooling water between inner barrel and outer barrel.However, lag cooler can not handle high temperature
Molten state material.Because high-temperature molten material can be sticked on blade during cooled and solidified, spiral blade is made to fail.
Therefore, at present China's steel and iron industry production in, the processing of high-temperature fusion blast furnace slag nearly all be using water quenching into
Row.There is following disadvantages for water quenching residues processing technique:
(1) water consume is high: for the country of water resource critical shortage, problem is particularly acute for this.
(2) a large amount of H is generated during Water Quenching Slag2S and SOx enters atmosphere with steam, causes environmental pollution.
(3) clinker sensible heat: the great UTILIZATION OF VESIDUAL HEAT IN value of 1450~1500 DEG C of liquid blast furnace is not recycled, but at home
The blast furnace slag waste heat rate of recovery is very low, and only 10% or so.
(4) need to be dried: blast furnace granulated slag moisture content is up to 10% or more, must be dried when as cement raw material, still
Consume certain energy.As described above, grain slag technique not only wastes a large amount of new water resource, and reduce the use effect of the energy
Rate, while also bringing environmental pollution.
The high-temperature products such as ferroalloy, silicon smelting, Smelting magnesium and calcium carbide production substantially use gravity-flow ventilation cooling, not only
Cooling time is long, very big stock ground is needed to stack place, and wastes a large amount of high-temperature residual heat resource.
Existing patented technology " a kind of high-temperature slag chilling dry process and the apparatus and method for recycling sensible heat ", publication number
Are as follows: CN 103320553B, slag trap, slag guiding trough, cooling roller group and slagging-off roller are in rotary drum outer surface along rotary drum rotation side in device
To successively arranging, it is equipped with slag particle collector below slagging-off roller, crusher is equipped with below collector, is returned below crusher equipped with waste heat
Receiving apparatus.High-temperature slag is put into the drum surface of rotation by slag guiding trough, high-temperature slag is transferred to rotary drum by rotary drum when work
Between cooling roller group, high-temperature slag is squeezed into slabbing, cooling and solidifying is transferred to the position of slagging-off roller, be then stripped into
Enter in slag particle collector, falls into after crusher and form particle slag through crushing, enter back into waste-heat recovery device.When the device works
There are chill roll sizings, and then lead to the stuck situation of chill roll, influence device normal operation.In addition, device does not have shell, work
When there are high temperature scald etc. risk factors.
Existing patent formula " processing method that a kind of blast furnace melts slag ", Publication No.: CN 104357606B, including roller
Chilling granulation system, lag cooler and residual neat recovering system.Roller chilling granulation system includes an inner-cooled list roller and two
Disintegrating slag deputy roller cylinder.Inner-cooled list roller is made of outer cylinder and inner cylinder, and the top half between outer cylinder and inner cylinder is equipped with cooling water pipe,
Cooling water pipe is equipped with nozzle, and lower half portion is water cavity and is connected with water outlet.In roller chilling granulation system high temperature material
The cooled water of heat is taken away, and therefore, the waste heat recovery efficiency of this method is relatively low.
Existing patent formula " a kind of liquid slag granulation and waste-heat recovery device ", Publication No.: N202830052U, it is main
It to be formed by slipping cinder notch, melt cinder bucket, quickly cooling chamber, star-like slag dumping wheel and air-cooled chamber.Quickly cooling chamber is divided into the granulating wheel group portion on top again
Divide the water quenching part with lower part.It is connected between quickly cooling chamber and air-cooled chamber by star-like slag dumping wheel, has water quenching part, so the device is not
It can be used for the cooling of calcium carbide high-temp. furnace material.
Existing patent formula " method and device that quenching dry type is crushed molten blast furnace slag sensible heat recycling ", Authorization Notice No.
Are as follows: heat transferring medium is exchanged heat with slag mixing chilling and promotes slag solidification, then distinguished by water and air by CN103820588B
The waste heat of high temperature heat transferring medium and high temperature clinker is recycled, realizes zero use of new water.This method is with the shortcomings that device
Heat transferring medium will continue to repeat in conjunction with molten blast furnace slag, separation process, lead to that system equipment is more, material flow is long, system is made
Valence is high, takes up a large area.
A kind of existing patent formula " dry type blast-furnace cement sensible heat recovery system ", Authorization Notice No. are as follows: CN206219613U, packet
Include cold slag ladle, waste heat boiler, conveyance conduit etc..Cold slag roller is set below cold slag ladle feed inlet, and cold slag roller is arranged in pairs, roller
There is cooling system in cylinder, cold slag roller rolls liquid slag, and clinker is fallen into after die mould in cold slag ladle.When the system works
Roller rotates towards each other, and high-temperature fusion slag squeezes that cooling distance is very short, and clinker is possible to not have at upright position on roller
Solid-state is condensed into, but is fallen under gravity into cold slag ladle；From upright position, furnace charge is likely to arbitrarily to from scarfing cinder plate
It falls off, these factors can all cause solid granulates clinker partial size in cold slag ladle to differ greatly, and influence cooling empty in cold slag ladle
The uniformity of gas.
