Abstract
The invention discloses an energy-saving low-temperature circular heating furnace. The heating furnace comprises a furnace body, a combustor, a high-temperature combustion chamber, a smoke circulating system pipe network, a circulating smoke high-temperature fan, a high-temperature smoke ejector, a control valve, an opened smoke exhausting pipe and a furnace door. The energy-saving low-temperature circular heating furnace has the beneficial effects that the environmental pollution is reduced; the use ratio of heat energy is promoted; the heat convection efficiency in a kiln is increased; the heat treating period of products is shortened; the temperature in the furnace is uniform and the technical quality is optimized; the fuels are fully burnt and the pollution on the products is reduced to the lowest; the heating furnace is strong in adaptability to fuels and can use urban coal gas, generator coal gas, natural gas and liquefied petroleum gas; the construction cost is low and the application scope is wide; the temperature adjustment is sensitive and accurate; and the temperature stability is excellent and the temperature difference in the furnace is small. The energy-saving low-temperature circular heating furnace can be applied to a heat treatment process of magnesium carbon bricks and dehydrating heat treatment processes of unfired bricks and poured prefabricated blocks in the industry of refractory materials.
Description
Technical field
The invention belongs to the thermal kiln furnace technical field, the energy-saving low temperature circular heating furnace that especially a kind of refractories industry is used.
Background technology
The heat treatment for solidification technology of magnesia carbon brick is that goods are heated to 180 ℃～200 ℃, and bond is solidified.Traditional handicraft adopts the electric heating kiln, promptly in cave dwelling, establishes electric hot plate or the quartzy width of cloth is penetrated heating tube, because this heat treatment is that to penetrate the heat transfer form with the width of cloth be main, firing rate is slow, the processing time long (one-period is 16～24 hours).Power consumption is big, and the heating element heater loss is also big.General processing brick total cost per ton is at 100～150 yuan.Some enterprises directly burning coal or heat-conducting oil heating technology on probation are also arranged, but effect is all undesirable.
Unburned brick and refractory precast block are handled, and tradition adopts the flaming of direct fuel burning to handle kiln, and temperature Centralized during operation, kiln temperature are inhomogeneous and wayward, handle of poor qualityly, and stoving time is long, the energy consumption height.
Summary of the invention
The invention provides a kind of energy-saving low temperature circular heating furnace, be applied to the dehydration fever treatment process of heat treatment, unburned brick and the casting preformed block of refractories industry magnesia carbon brick.
Energy-saving low temperature circular heating furnace provided by the invention is according to the desired thermal technology's processing feature of Low Temperature Heat Treatment stove, according to thermal technology's basic principle; That should discharge is not less than 180 ℃ of flue gas recirculation utilizations; And the flow velocity of hot flue gas medium in the stove is increased through the high temperature circulation blower fan, and go into the stokehold once more at flue gas and controllably replenish high-temperature flue gas, convection heat transfer' heat-transfer by convection efficient significantly improves; The processing time of material is shortened greatly, reach smoke discharge amount and reduce and purpose of energy saving significantly.
Energy-saving low temperature circular heating furnace provided by the invention comprises with lower component:
Body of heater, burner, high temperature combustors, flue gas recirculation system pipe network, circulating flue gas high-temperature blower, high-temperature flue gas injector, by-pass valve control, open circuit smoke discharge pipe, fire door.Bottom of furnace body and all around the sealing, above opening, fire door is at opening part; Burner connects high-temperature flue gas injector and flue gas recirculation system pipe network; High temperature combustors is in burner; The flue gas recirculation system pipe network passes body of heater, and the high-temperature flue gas that high temperature combustors produces is through flue gas recirculation system pipe network heating furnace body; Circulating flue gas high-temperature blower and by-pass valve control are connected in the flue gas recirculation system pipe network, and the flue gas of being extracted out by body of heater blasts body of heater once more through the recyclegas blower fan; Open circuit smoke discharge pipe and by-pass valve control are installed in flue gas recirculation system pipe network upper shed between circulating flue gas high-temperature blower and high-temperature flue gas injector, are heated goods and put into stove through fire door.
The present invention with compare its significant beneficial effect with existing low-temperature heat stove and be embodied in:
1. owing to adopt flue gas recirculation, only open circuit is emitted the sub-fraction flue gas, has reduced environmental pollution and has improved utilization efficiency of heat energy.With similar traditional burner than its energy consumption cost low 40%～80%.
2. owing to adopt flue gas recirculation, improve the inner flue gas of the stove flowing velocity, increased the heat convection efficient in the kiln, shortened the heat treatment cycle of goods, improved production efficiency.
3. owing to improved the furnace gas flow velocity, make the interior temperature of stove even, processing quality optimization.
4. owing to be provided with the high temperature highly effective combustion system, make fuel combustion complete, flue gas pollutant reduces in a large number, drops to minimum to the pollution of goods.
5. this reheat furnace system is strong to fuel tolerance, can use town gas, producer gas, natural gas, liquefied petroleum gas.
6. this energy-saving low temperature circular heating furnace construction cost is low, maintenance is little, the life-span is long, and the scope of application is wide.
7. this energy-saving low temperature circular heating furnace adjustment is sensitive, accurate, has a narrow range of temperature in furnace temperature good stability, the stove.
