Abstract
The utility model discloses a fluidized bed furnace for a grain drying tower, which comprises a furnace body, a fluidized bed chamber, a combustion chamber, a cowl, a settling chamber, a coal feed inlet, a hot smoke outlet and a fan. A refractory material is arranged on the inner layer of the furnace body, the fluidized bed chamber and the combustion chamber are disposed in the furnace body, the cowl is arranged below the fluidized bed furnace, a slag discharge hole, a slag discharge pipe and a constant-pressure air box are arranged below the cowl, and the bottom end of the air box is communicated with the fan arranged on one outer side of the furnace body via an air duct. The coal feed inlet and a fire door are arranged in the front of the furnace body, and the hot smoke outlet is arranged on the rear side of the furnace body. The fluidized bed furnace adopts coal gangue as fuel, and the coal gangue can be in fluidized-bed combustion sufficiently by uniform air supply from the cowl. Since the coal gangue is low in price, slag after fluidized-bed combustion can be used as a raw material for production of cement, the fluidized bed furnace can save drying cost for grain storage enterprises by 30%, and accordingly has low production cost which is less than 50% of other furnaces. The fluidized bed furnace is capable of reducing discharge of pollutants, saving energy and reducing emission, has remarkable economical benefits, and is suitable to be popularized and applied for grain drying enterprises.
Description
Technical field
The utility model relates to grain drying device, is specifically related to a kind of grain drying tower fluidized bed furnace.
Background technology
China has several ten million tons of various grains to need oven dry every year, goes mouldy in order to prevent stock's grain, and grain depot all will be dried processing to the grain of warehouse-in every year.At present, the grain drying tower that grain depot generally uses (machine) all is heating equipment with stoker fired grate moulded coal stove, the manufacturing cost height of drying oven, and the fat coal that need burn, it is not thorough to burn, and along with constantly riseing of burned coal price, causes the cost of grain heat-drying to increase day by day.
The utility model content
The utility model purpose is to provide a kind of grain drying tower fluidized bed furnace, uses the utility model can make grain heat-drying cost savings 30%.
For achieving the above object, the utility model grain drying tower fluidized bed furnace, comprise body of heater, boiling-house, combustion chamber, blast cap, expansion chamber, feed coal mouth, hot exhanst gas outlet and blower fan, described body of heater internal layer is provided with refractory material, boiling-house and combustion chamber are set in the body of heater, blast cap are set below the boiling-house, slag-drip opening and scum pipe are set below the blast cap, also be provided with below the blast cap and all press bellows, the bellows bottom is connected with the blower fan that is arranged on the outer side of body of heater by airduct.The front of body of heater is provided with feeds coal mouth and fire door, and the rear side of body of heater is provided with hot exhanst gas outlet.
Back, described body of heater inner combustion chamber also is provided with expansion chamber, is provided with ash releasing tube below the expansion chamber.
Described body of heater front also is provided with coke cleaning mouth and cleaning door.
The utility model grain drying tower adopts inside and outside double-layer structure with the body of heater of fluidized bed furnace, the outer common building material that adopts, and internal layer adopts refractory material, and boiling-house and combustion chamber are set in the stove, is provided with expansion chamber simultaneously.The utility model is fuel with the gangue, evenly make gangue can reach abundant Boiling Combustion for wind through blast cap, because gangue is cheap, but and the making cement raw materials for production also of the lime-ash after the Boiling Combustion, so the utility model oven dry grain, can be grain and store enterprise's saving 30% oven dry cost, and the fluidized bed furnace low cost of manufacture, less than 50% of other stove cost.
Below in conjunction with accompanying drawing the utility model is described in further detail
Description of drawings
Fig. 1, Fig. 2, Fig. 3 are respectively the cutaway view of the utility model grain drying tower with front view, vertical view and the left view of fluidized bed furnace
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model grain drying tower fluidized bed furnace, comprise body of heater 1,2, boiling-house 14, combustion chamber 15, blast cap 13, expansion chamber 11, feed coal mouth 3, hot exhanst gas outlet 9 and blower fan 8, described body of heater are double-layer structure, and outer 1 adopts the common building material, internal layer 2 adopts refractory material, boiling-house 14 and combustion chamber 15 are set in the body of heater, blast cap 13 are set below the boiling-house 14, slag-drip opening 10 and scum pipe 6 are set below the blast cap 13, also be provided with below the blast cap 13 and all press bellows 12, bellows 12 bottoms are connected with the blower fan 8 that is arranged on the outer side of body of heater by airduct.The front of body of heater is provided with feeds coal mouth 3 and fire door 4, and the rear side of body of heater is provided with hot exhanst gas outlet 9.
15 back, described body of heater inner combustion chamber also are provided with expansion chamber 11, are provided with ash releasing tube 7 below the expansion chamber.
Described body of heater front also is provided with coke cleaning mouth 5 and cleaning door 17.
When using the utility model oven dry grain, earlier gangue is pulverized, the heat exchanger of hot exhanst gas outlet 9 of the present utility model and grain drying tower is connected, gangue after the pulverizing is inserted boiling-house through feeding coal mouth 3, the high-pressure blast that high pressure positive blower produces is through airduct with after all pressing bellows 12 all to press, form uniform high pressure stratification of wind by blast cap 13 gangue in the fluidized bed furnace is formed the Boiling Combustion state, seethe with excitement highly about 1 meter, fully burning in the combustion chamber, because gangue is in the fluidized state burning, oxygen supply is abundant, make the complete after-flame of gangue, the control furnace temperature can be by feeding the adjustable electromagnetic feeder on coal mouth 3 tops, and the control feed quantity gets final product, and furnace temperature can be adjusted control arbitrarily in 500-1000 ℃.The spoil slag of after-flame is arranged down through scum pipe 6 by bottom slag-drip opening 10, and removes through cleaning door 17.For reaching environmental protection, the utility model also is provided with expansion chamber 11, can make hot flue gas before exporting dust fallen into expansion chamber, has reduced the discharging of pollutant.The utility model cost is low, energy-saving and emission-reduction, and remarkable in economical benefits is adapted at the grain heat-drying business enterprise expand and uses.
