The purpose of this utility model provides a kind of molten steel scum heat-energy recovering apparatus; sensible heat when this device makes full use of the warm sludge discharging; by converting cold slag particleization; warm sludge concentrated in the storage tank realize energy recovery; technology is simple, cost is low, effective used heat resource of having utilized, and the slag after the subzero treatment also can carry out the recycling of iron.
For achieving the above object, the utility model is achieved through the following technical solutions:
The device of molten steel scum energy recovery, comprise fusion slag ladle, cold slag injector, mix slag ladle, distributor, hot blast recovery tube, chassis, fan housing, travelling belt, cold slag injector is arranged at top or the sidepiece that mixes slag ladle, and the fusion slag ladle is positioned at the top of mixing slag ladle; Between the slag notch of chassis and mixing slag ladle, be provided with distributor; Transport on the section of transporting of mixing slag at chassis and to be provided with fan housing, the chassis bottom is provided with cold air inlet, and hot-blast outlet is arranged at chassis top.
Described mixing slag ladle bottom is provided with the secondary granulating device, and the secondary granulating device is that two pair rollers that all inwardly rotate constitute.
Compared with prior art, the beneficial effects of the utility model are:
1) rationally utilizes the used heat resource, turn waste into wealth energy-saving and emission-reduction.
2) make full use of the sensible heat that warm sludge discharges, reach high efficiente callback, effectively utilize residual heat resources.
3) the device layout is easy, by the continuous granulation of realization, heat transfer process on the device, and the equipment less investment, simple in structure.
4) the dust gas that produces in the heat recycle process can purify through material, no dust discharge, the purpose of realization energy-conserving and environment-protective.
5) the cold conditions waste can be used to produce cement or ultrafine powder, helps realizing the zero release of waste.
Description of drawings
Fig. 1 is the structural representation of molten steel scum heat-energy recovering apparatus.
Embodiment
Be described in detail the utility model below by embodiment.
See Fig. 1; the device of molten steel scum energy recovery; comprise fusion slag ladle 1, cold slag injector 2, mix slag ladle 3, secondary granulating device 4, distributor 5, hot blast recovery tube 6, chassis 7, fan housing 8, travelling belt 9; cold slag injector 2 is arranged at top or the sidepiece that mixes slag ladle 3, and fusion slag ladle 1 is positioned at the top of mixing slag ladle 3.Mix slag ladle 3 bottoms and be provided with secondary granulating device 4, between the slag notch of chassis 7 and mixing slag ladle 3, be provided with distributor 5.Transport on the section of transporting of mixing slag at chassis and to be provided with fan housing 8, in fan housing, finish cold wind and mix the heat exchange of slag.The chassis bottom is provided with cold air inlet 10, and hot-blast outlet 11 is arranged at chassis top, and the hot blast of deriving by hot blast recovery tube 6 enters waste-heat recovery device.
Adopt this device with blast furnace or converter molten steel scum in a spot of cold conditions iron and steel slag is inserted the insulation slag ladle, mix, make and form slag bath in the slag ladle; By the granulation of cold slag to the molten steel scum, increase heat interchanging area, make the heat energy of melting slag obtain efficient recovery; The process of energy recovery is by being blown into cold wind, after the cold wind heating hot blast being imported waste heat boiler and realize.
This device can make the heat energy of 1400-1500 ℃ molten steel be able to efficient recovery; be used for the heat recovery device; after hot slag and cold conditions slag carry out heat exchange; the temperature of mixing slag reaches 900-1000 ℃; slag ladle bottom is provided with warm sludge secondary granulating device, can make not conforming to the granularity slag and can reach next step processing requirement in the warm sludge.After one section cold and hot exchange, waste residue is discharged at slag notch.Whole melting slag cooling, cold wind adds the energy of thermogenesis in the waste heat boiler utilization, and low temperature waste gas can draw again gets back to the hot rolling cooling system, forms closed cycle.
