Description
Technical field
The utility model is related to slag comprehensive utilization technical field, especially a kind of heat insulation furnace cover of steel slag cracking furnace.
Background technology
The stewing cracking technology of cracking oven process hot steel slag heat be temperature be up to more than 1000 DEG C hot steel slag low-carbon (LC), environmental protection,
The efficient state-of-the-art technology that utilizes, its technological principle is during hot steel slag poured into steel slag cracking furnace, vehement in steel slag cracking furnace
The processes such as the successively experience steam bath from top to bottom of hot slag is cold, misting cooling, heat stewing cracking, waste heat recovery.
In steam bath cold belt, newly pour into the temperature in steel slag cracking furnace and be up to more than 1000 DEG C of hot steel slag and come from
The low-temperature saturated steam bath of misting cooling band is cold, and slag temperature is rapidly reduced to less than 800 DEG C, including slag by more than 1000 DEG C
Tentatively crushed in the presence of outer thermal (temperature difference) stress；In water-spraying control band, the middle temperature to temperature below 800 DEG C from top to down
Slag surface atomizing is sprayed water, and slag temperature is further reduced, and at the same time the f-CaO in slag and f-MgO occurs violent
Hydration reaction generates Ca (OH) 2 and Mg (OH) 2 and produces volumetric expansion, and swelling stress makes slag further be crushed；It is stewing in heat
Cracking band, the water that slag is injected into continues cool to less than 80 DEG C, and f-CaO therein and f-MgO continues hydration swelling and makes steel
Slag is cracked completely.
During hot steel slag experiences the stewing cracking band of steam bath cold belt, misting cooling band, heat from top to bottom, penetrating
Water is heated vaporization, and steam through the stewing cracking band of overheat, misting cooling band and steam bath cold belt, is finally arranged by furnace roof from bottom to top
Go out, and be imported into low-temp low-pressure saturated vapor heat reclaiming system, so as to realize the recycling of hot steel slag sensible heat.
It is the weight that can reliably carry bell itself to the basic demand of steel slag cracking furnace bell, and by red-hot
Vibration and the influence of impact that slag is produced when pouring into steel slag cracking furnace from slag ladle；Bell has stronger heat resistance in itself
Can, so that it remains to remain intact in the case of by hot steel slag long term high temperature thermal radiation；Bell will have preferably insulation
Performance；Bell should also have good sealing property, not admit air into heat reclaiming system, steam is not made yet to leaking
Leakage.
The content of the invention
The purpose of this utility model be exactly it is bad to solve the boiler roof sealing and heat insulating ability of existing steel slag cracking furnace,
And a kind of heat insulation furnace cover of steel slag cracking furnace is provided.
The technical solution of the utility model is：A kind of heat insulation furnace cover of steel slag cracking furnace, with body of heater, the top of body of heater fills
There is bell, bell center is provided with feed pipe, and feed pipe upper end is flange arrangement, and push-pull valve, upper of furnace body are housed on flange arrangement
Side wall is provided with steam fairlead, valve is housed, particularly on steam fairlead：The bell is hollow body structure, case
Body includes top board, base plate and side plate, and the top board, base plate and side plate are using steel plate material and are welded into an entirety knot
Structure, built with intersecting parallels spandrel girder, groined type spandrel girder is welded by I-steel or channel-section steel to casing, intersecting parallels spandrel girder
Top board and base plate of the upper and lower wing plate respectively with casing are welded, and casing center is provided with feed pipe, right on roof box and base plate
Answer feed pipe to be provided with through hole, feed pipe through box house intersecting parallels spandrel girder center mouth word and with the top board and base plate of casing
It is welded, light heat insulating material is filled with the space of box house.
Bell material described in the utility model is heat resisting steel or cast iron.
Heat preserving and insulating material described in the utility model is blast furnace granulated slag, expanded perlite, asbestos, glass fibre or lightweight
Any one or a few in castable refractory.
Valve on steam fairlead described in the utility model is electric butterfly valve.
The utility model simple structure, it is safe and reliable, hollow body structure is designed as by by bell, set in casing
Intersecting parallels spandrel girder is put, makes the weight of bell itself by the intersecting parallels load-bearing load bearing beam inside bell, and load is uniform
It is assigned on working lining, heat insulation furnace cover center is provided with feed pipe, and is provided with push-pull valve in feed pipe upper end, when loading operation is completed
Afterwards, closing push-pull valve can make furnace roof be in sealing state, will not admit air into heat reclaiming system, also will not be to outward leakage
Steam.
