Background technology
The direct-fired high hot-blast stove that purifies also can be referred to as high flue stove based on its working condition, adopts fuel directly to burn exactly, forms flue gas and the dry or baking with the material Direct Contact Heating of uniform temperature through high purified treatment.The consumption of this method fuel is approximately than reducing about 20% to 50% with steam-type or other indirect heaters.Therefore, under the prerequisite that is not influencing the oven dry product quality, can use the direct-fired high hot blast-be high flue of purifying fully.Its fuel can be divided into: solid fuel, like Flammable Solid Class 4.1 such as coal, firewood, poor slags; Liquid fuel is like diesel oil, heavy oil, heavy oil residue, Aalcohols fuel; Gaseous fuel is like producer gas, coke-stove gas, natural gas, oil liquefied gas, biogas.High-temperature flue gas that fuel obtains after combustion reaction and the air in the environment directly get into hothouse or bakery after being mixed into certain design temperature, contact with the material that is dried, and heating, transpiring moisture, thus obtain dry products.In order to utilize the heat of reaction of these fuel combustions, must set up a cover fuel burner like coal burner, fuel oil/air burner, fuel oil/gas burner, traveling-grate stoker etc.
Indirect heat exchange formula hot-blast stove can be referred to as real hot-blast stove according to its working condition, because it is that pure air is heated fully, what obtain is the free of contamination hot-air of pure cleaning.Indirect heat exchange formula hot-blast stove is mainly used in the material that is dried and does not allow contaminatedly, or is applied to the drying of the lower heat sensitive material of temperature, as: food, milk powder, pharmacy, synthetic resin, fine chemistry industry etc.The essence of indirect heat exchange formula hot-blast stove is heat exchange.Can utilize steam, conduction oil, flue gas as carrier, the heat exchanger through various ways adds hot-air, and in this sense, all indirect type hot blast heat exchangers all can be referred to as hot-blast stove, and its heater is then varied.This place says that hot-blast stove just is meant the medium of the flue gas of utilization burning formation as the heats cold air in general, utilizes the heat-exchanger rig of heat exchanger as air and flue gas, has the assembly of burner and hot blast heat exchanger simultaneously.It is found that heat exchanger structure and member thereof are extremely huge for the influence of heat exchange effect, even be directly connected to the service life of heat exchanger.Judge that the most basic one of hot-blast stove energy-saving effect quality is exactly the height of flue-gas temperature after reaching the hot blast temperature heat exchange.Flue-gas temperature is low more, and heat utilization efficiency is just high more, otherwise then the thermal efficiency is lower.
The utility model content
The purpose of the utility model provides a kind of tower stove, and its floor space is little, low cost of manufacture, maintenance convenient.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
Tower stove includes body of heater, is provided with the several layers drying-plate in the said body of heater; Form drying cavity between drying-plate and the sidewall of the furnace body, said drying-plate has the opening that supplies the baking material to pass through, the interleaved openings setting of each drying-plate; Also be provided with the feeding rake in the body of heater, the feeding rake makes the baking material, and drying-plate moves toward lower floor's drying-plate from the upper strata, and the body of heater top has charging aperture; Bottom of furnace body is provided with discharging opening, and the baking material after the oven dry is discharged from discharging opening, is provided with air inlet, preheating gas port and hot gas mouth from bottom to up in order near the sidewall of the furnace body of discharging opening; Air inlet, preheating gas port and hot gas mouth are communicated with the inner drying cavity of body of heater respectively; Extraneous air gets in the body of heater from air inlet, and coming out of the stove through the preheating gas port through pre-warmed air gets into the combustion chamber, is got in the body of heater through the hot gas mouth by the air after the heating of combustion chamber; Upper of furnace body also is provided with exhaust outlet, and the air that flow to top from the body of heater bottom is discharged from this exhaust outlet;
Further, the drying-plate opening that is positioned at air inlet and hot gas mouth place has been provided with the normally closed air door of isolated air-flow effect, during the feeding of feeding rake air door is backed down;
In addition, said side wall of furnace is provided with side door, makes things convenient for the maintenance of body of heater.
The advantage of the utility model is, this drying oven adopts multilayer vertical, and under the effect of feeding rake, the baking material in layer moves down along drying-plate the baking material after the charging of upper strata; Combustion gas gets into from lower floor, and with the reverse flow of baking material, sandwich construction, floor space is little; Baker is the most two-layer blows with air blast, and air flow continues transpiring moisture when making the cooling of baking material, directly gets into the combustion chamber through heat-exchanged air, can save the energy; The furnace bottom layer is established the twice air door, plays isolated air-flow effect at ordinary times, when the feeding of feeding rake, backs down air door, and material stays from air door; Baker is made box, and the side door of baker is detachable, is convenient to very much maintenance.
