Description
Technical field
A kind of heating system is the utility model is related to, especially a kind of coal damping heating system, belongs to coal process field.
Background technology
Be divided between existing standby coal car unload, two processes of coal blending；The unloading of the external coal of primary recipient of unloading coal, heap takes work, matches somebody with somebody
Coal mainly undertakes the transport of coke oven coal charge, crushed work；But the outdoor storage of rickyard, coal is thin in addition, viscous, hardened and moisture surpasses
Height, moisture is high after causing cooperation crushing, influences coke oven hot index, aggravation shove charge operation, increases coke oven heat dissipation, the cake that collapses etc. and work
Amount increases.
Coal humidifying technology is dried using gas-fired heat as main heating source to wet coal, and stack gases are by mixing wind furnace
Into heat supplemented by coal damping rotating cylinder, the two combines to form thermal current and the coal charge of rolling carries out heat exchange and reaches evaporation moisture
Effect, this operation can obtain drop point dewatering effect.
Check that coke oven flue waste gas has 20.06% H20 through analysis, heat exchange, coal gas are carried out through 20 meters of rotating cylinders after mixing
Combustion high temperature heat mixes with low temperature flue gas necessarily causes temperature to reduce, while evaporates vapor in flue gas and expend big calorimetric
Amount；The temperature of gaseous mixture is not only reduced, or even large quantity of moisture is brought into coal so that moisture content of coal is unable to maximum mode removal, because
This is necessary to be used to 150-180 ° of waste gas again, and then, on the basis of existing, it is badly in need of a kind of coal damping heating system.
The content of the invention
To reduce cooperation moisture content of coal to greatest extent, coal damping production capacity is improved, meets that coke oven produces, this novel practical carries
It is as follows for a kind of coal damping heating system, concrete scheme：
A kind of coal damping heating system, including dryer and some air-introduced machines connected with dryer, it is characterised in that：Institute
Stating dryer includes interior airduct, and the body of interior airduct is provided with swash plate and some ventilation elbows, and some ventilation elbows are uniformly distributed
In swash plate both sides, the tube wall of interior airduct is also provided with some air vents, and some air-introduced machines pass through some fume pipes and dryer
Interior airduct connection, and some fume pipes located at drying machine tail end.
Further, box flashboard is equipped with some flues.
Further, the dryer also includes the lifting blade located at cylinder Inner Front End.
Further, the swash plate has two pieces, and two pieces of swash plate one end are on interior airduct, and the other end is connected with each other, swash plate
It it is 60 ° with horizontal plane angle.
Further, the air-introduced machine is 3.
Further, the dryer also include the bull gear in the middle part of the cylinder, the front-wheel band located at barrel front end and
Located at the trailing wheel band of cylinder back-end, the preceding support roller and rear support roller of cylinder lower end coordinate with front-wheel band, trailing wheel band successively, drive device
Cylinder is driven by bull gear.
Further, preceding sealing and rear sealing are additionally provided with the cylinder.
Compared with prior art, the utility model has following beneficial effect：
Overall structure is novel, compact, sets stack gases to enter dryer by afterbody, mitigates heat exchange and brings the steaming of coal reclaimed water into
Gas, the coal charge that back-end ductwork gas is kicked up lifting blade by interior airduct carry out secondary injection and drying, vapor in coal are dispelled,
Induced draft blower withdraws ability is reduced, steam is directly pumped to dust pelletizing system from afterbody, contrasted through moisture, can show that drum outlet drops more
Moisture 0.5-1.0%；Greatly improving moisture reduces efficiency；Important function is got to stablizing coke oven production and reducing coking heat dissipation.Cigarette
Nitrogen content is up to 68% in road waste gas, can reduce hood position because high temperature remaining dust produces fire risk, improve overall behaviour
Make security.
