The purpose of this utility model is to provide a kind of mode of vibration and the combination of shallow fluid bed that can adopt and carries out the cooling of high temperature furnace slag, adopt the batcher that has cooling structure to control the flow of high temperature furnace slag simultaneously, and then realize the continuous blow-down of fluid bed slag and the commercial plant of cooling.
The purpose of this utility model is achieved in that it is made up of charger 3 and discharging machine 13 and three major parts of slag cooler body, it is characterized in that body is provided with the reciprocal straight-line oscillation of the self-balancing type of being made up of both sides vibrating motor 9 system.It is charger that high temperature furnace slag at first enters an electro-vibrating feeder that has air-cooled or water-cooling structure, to realize quantitatively controlling the flow of slag, enters the vibrated fluidized bed slag cooler then.Cold wind enters cooling chamber from air compartment through air distribution plate, carries out the direct contact type heat exchange with slag on the air distribution plate.Because adopt lower fluidizing velocity, the natural layering phenomenon vertically appears in material; Bigger particle is energy fluidizing not, is subjected to vibration force to do to travel forward in order to the moving bed form; Then being fluidized the back than granule follows the material main body at bed face and travels forward.After being cooled, slag discharges through discharging machine 13 from slag notch 12; Discharge from air outlet 7 behind the heat of cold wind acquisition slag.
Effect of the present utility model compared with prior art has following characteristics: it adopts the continuous and quantitative control technology of high temperature sludge, the combination of the surface bed fluidization technology of body vibrotechnique and the heat exchange of enhancing particle." channel " and fluidisation inequality have not only been avoided in the vibration of material effectively, and make Flow of Goods and Materials unimpeded; Fluidization technology has strengthened the heat transfer between gas-solid; Vibration has strengthened the contact between gas-solid; Surface bed reduces the power consumption of air blast.The combination of above-mentioned multiple factor not only makes the mobile highly stable of material, and makes between gas-solid heat exchange very abundant, and the heat recovery rate of slag cooler reaches 85%～94% when 2t/h～4t/h, and the wind slag ratio is lower than 2.In addition, this equipment volume compactness, cost is low, be convenient to and the supporting use of the fluidized-bed combustion boiler of various ways, have and economize on coal, smooth combustion and steam parameter, reduce the power consumption of boiler, reduce flue gas and heat loss due to sensible heat in slag, improve the overall economic efficiency of boiler thermal output.
