Abstract
The utility model relates to an energy-saving and cost-reducing device, in particular to a surplus heat utilization device for a moulded coal kiln, which solves the problem that the hearth exhaust gas of the prior moulded coal kiln is directly discharged to cause energy source waste and environmental pollution. The surplus heat utilization device comprises an exhaust gas discharge outlet positioned at the hearth of the kiln, wherein an exhaust gas conveying pipe is arranged on the exhaust gas discharge outlet; the tail end of the exhaust gas conveying pipe is connected to a coal-burning air heating furnace which provides drying medium for the kiln and the air outlet of coal-burning air heating furnace; the exhaust gas conveying pipe is provided with a dust catcher, or the tail end of the exhaust gas conveying pipe is connected to the lower part of a fire grate of the coal-burning air heating furnace. On the premise that the original drying mode is not changed, the utility model can circularly utilize the exhaust gas generated from the hearth of the kiln, can reduce the energy consumption for drying by 20-40 percent, utilizes the nearby resources, decrease process equipment, reduces the production cost, saves the energy sources, and has simple structure, simple operation, obvious energy-saving effect and certain generalizing value.
Description
Technical field
The utility model relates to a kind of energy saving device, is specially a kind of Furnace drying briquette residual heat using device.
Background technology
At present, the Furnace drying briquette drying medium all adopts open system, be that drying medium (flue gas) that hot-blast stove produces blasts drying oven by drying air fan and the material that is dried carries out all directly entering or all enter atmosphere after the heat exchange (dry run) behind cleaner.After deliberation, 60%～80% waste gas that drying oven produces is discharged through furnace roof, and it is saturated that humidity is tending towards, and sensible heat seldom, no value, and 20%～40% waste gas is discharged by furnace bottom, and humidity is little, sensible heat is higher, can effectively utilize, but effectively do not utilize this part energy at present, cause energy loss, and these discarded being discharged in the air, can produce greatly influence to environment.
Summary of the invention
The utility model directly discharges in order to solve existing Furnace drying briquette furnace bottom waste gas, causes energy waste and problem of environment pollution caused, and a kind of Furnace drying briquette residual heat using device is provided.
The utility model is to adopt following technical scheme to realize: the Furnace drying briquette residual heat using device, comprise the Waste gas outlet that is positioned at the drying oven furnace bottom, Waste gas outlet is provided with waste gas pipeline, the terminal coal-fired hot-blast stove that drying medium is provided to drying oven that inserts of waste gas pipeline.Adopt structural design of the present utility model, the waste gas of being discharged by the drying oven furnace bottom enters coal-fired hot-blast stove again through waste gas pipeline and carries out recyclingly, has reduced energy consumption and production cost, has reduced the environmental pollution that direct discharging causes.
Furnace bottom waste gas recycling has dual mode, the one,, the terminal air outlet that inserts coal-fired hot-blast stove of waste gas pipeline is equipped with deduster on the waste gas pipeline, clean high-temp waste gas after dedusting directly enters drying oven by the air outlet of coal-fired hot-blast stove, as drying medium; The 2nd,, the terminal coal-fired hot-blast stove fire grate below of inserting of waste gas pipeline is again in the coal-fired hot-blast stove internal combustion.
Compared with prior art, the utility model is keeping under the constant prerequisite of former drying mode, the waste gas circulation that the drying oven furnace bottom produces is used, can be made energy consumption for drying reduce 20-40%, and utilize nearby, reduce process device, reduce production costs, energy savings, the utility model is simple in structure, easy and simple to handle, energy-saving effect is obvious, has certain popularization value.
