Abstract
The utility model relates to a cyclic slideway drier, which comprises a drying chamber with an air distribution port and a smoke vent. The cyclic slideway drier is characterized in that hot air ducts are parallelly arranged beside the drying chamber; both the drying chamber and the hot air ducts are provided with a closed-loop slideway; a fire grate motor trolley is arranged on the closed-loop slideway and is provided with a drive mechanism for the fire grate motor trolley; the top part of the drying chamber is provided with an air collection chamber, and the lower part of the drying chamber is provided with an air distribution chamber; and the air distribution port of the air distribution chamber is connected with the hot air ducts through a hot air pipe and an air blower. The cyclic slideway drier has the advantage that boiler end gas can be taken as hot air resource for drying to realize the drying at the low temperature of between 200 DEG C and 150 DEG C, so that heat consumption is low and heat utilization rate is improved; a motor trolley fire grate is adopted to arrange coal, and the fire grate motor trolley circularly moves along the slideway, so the coal can be effectively and uniformly dried by hot air; the size of the drier and the number of the motor trolleys can be determined according to actual requirements, and drying area is greatly increased; the air distribution chamber which is arranged at the bottom of the cyclic slideway drier can play a role in final dusting; and the cyclic slideway drier avoids coal ash pollution, and can reduce smoke dust density.
Description
Technical field
The utility model belongs to a kind of coal-fired drying equipment, particularly a kind of circulation guide rail drying machine.
Background technology
Mostly about 10-20%, the brown coal water content is more up to 30% for the coal-fired moisture content of China, because coal-fired water content is higher, causes the fired coal combustion calorific value to descend, and identical heat increases freight volume down.Therefore to dry especially brown coal oven dry be the important behave that improves coal-fired calorific value and save transport power to coal.
At present, the coal in China dry technology is comparatively backward, and existing coal drying equipment adopts the cylinder-rotating drying.Because coal rotates in cylinder, cause most of coal dust to be taken away by hot blast, not only cause energy loss, also caused the pollution of air ambient, the drum-type coal drying needs the hot blast more than 600 ℃ simultaneously, heat energy expends height, and equipment exhaust emissions temperature is up to 100-120 ℃, and the heat energy utilization rate is lower.Equipment occupation space is big in addition.
The utility model content
The purpose of this utility model provides a kind of circulation guide rail drying machine, does not have coal ash pollution, also can remove the concentration of flue dust in the low cigarette institute, and heat energy expends low, raising heat energy utilization rate, and equipment occupation space is little.
The purpose of this utility model is achieved by the following technical solution: it comprises the hothouse of band cloth air port and exhaust opening, it is characterized in that: the hothouse side is provided with hot-flow flue arranged side by side, in the hothouse with on the hot-flow flue closed loop guide rail is set, the fire grate railcar is arranged on the closed loop guide rail, and fire grate railcar driving mechanism is set, the top of hothouse is wind assembling set, and the bottom is an air compartment, and the cloth air port of air compartment is connected hot-flow flue by warm-air pipe with blower fan.
Advantage of the present utility model:
1, can utilize boiler exhaust gas as the oven dry hot blast energy, realize 200 ℃-150 ℃ low temperature drying, heat energy expends low, improves the heat energy utilization rate.
2, adopt railcar fire grate cloth coal, the fire grate railcar along orbital cycle move, coal distributes on the air distribution plate equably, can guarantee that hot blast dries coal effectively equably.
3, circulation guide rail drying machine adopts the orbital cycle motion, can determine the size of drying machine and the quantity of railcar according to actual needs, has greatly improved the oven dry area.
4, circulation guide rail drying machine bottom air compartment is simultaneously also as secondary ash collector, and after flue gas entered air compartment, because dilatation rapidly, flue gas flow rate descended, and most of flue dust also can be separated from flue gas under the effect of gravity, plays the effect of final dusting.Not only do not have coal ash pollution, can also reduce the concentration of flue dust.

Fig. 3 is the B-B revolved sectional view of Fig. 1.
The specific embodiment
See Fig. 1-3, concrete structure is as follows: at the hothouse 3 other hot-flow flues arranged side by side 10 that are provided with, in the hothouse 3 with above the hot-flow flue 10 closed loop guide rail 1 is set.The fire grate railcar 2 of a plurality of tape running wheels 15 is arranged on the closed loop guide rail 1, and fire grate railcar driving mechanism is set, the drives structure of railcar can be taked prior art, also can take following structure: be provided with the shifting part 13 that drives by motor 14 below guide rail 1, shifting part 13 is to connect driving lever on the disk that rotates.Stir 2 operations of a railcar by shifting part 13, and this railcar 2 promotes previous operation, transferring power successively.The top of hothouse 3 is wind assembling set 3.1, and the bottom is an air compartment 3.2, and the cloth air port 12 of air compartment 3.2 is connected hot-flow flue 10 by warm-air pipe 16 with blower fan 17.Hot-flow flue 10 is communicated with boiler exhaust gas outlet 11.The exhaust opening 4 of wind assembling set 3.1 connects chimney 8.The circulation guide rail drying machine that the utility model provides can be designed to the single-row or multilayer multiple row structure of individual layer.
Operation principle: employing be railcar fire grate cloth coal form, fire grate railcar 8 is along the guide rail shuttling movement, coal is evenly distributed on the railcar fire grate, hot blast equably by the coal seam, does not have coal dust to be taken up by hot blast from railcar bottom air compartment 13, after flue gas enters air compartment 13 simultaneously, because dilatation rapidly, flue gas flow rate descends, and most of flue dust also can be separated from flue gas under the effect of gravity, plays the effect of final dusting.
