The utility model has the advantages of compact structures, large heat exchange area, good cool-down effect, powerful force, low slag temperature without slag blockage, low power consumption, small noise, strong security without strong extrusion pressure, light abrasion and long useful time, thereby being beneficial to environment protection and energy saving, and widely applicable to the double-cylinder roller slag cooler for the boiler furnace cinder process.
Description
Affiliated technical field the present invention relates to a kind of double-cylinder type rotary drum cold slag machine drum body, can be widely used in the double-cylinder type barrel slag cooler of boiler slag processing.
Background technology is along with boiler capacity continues to increase, and exerting oneself of cold slag machine required also improving constantly, and the cooling effect of slag is directly connected to the safe and stable operation of the follow-up equipment of slagging tap, and handles badly, can influence the operation of boiler.Existing cold slag machine drum body, be generally monotubular formula structure, be subjected to the restriction of himself structure and installing space, its heat exchange area is little, can not satisfy the requirement of exerting oneself greatly, if use reluctantly, will certainly cause the tapping temperature height even go out red slag phenomenon, badly influence the safety in production of boiler.
Summary of the invention the object of the present invention is to provide that a kind of compact conformation, heat exchange area are big, good cooling results, exert oneself greatly, stifled slag, tapping temperature is low, low in energy consumption, noise is little, high safety, no strong extruding force, light abrasion, long service life, help the double-cylinder type rotary drum cold slag machine drum body of environmental protection, energy savings.
In order to achieve the above object, double-cylinder type rotary drum cold slag machine drum body of the present invention, comprise the spiral tank is set in the interlayer, inwall is provided with lifting blade and the crisscross outer cylinder body that is the Omasum shape of helical blade, be installed in the spiral tank be set in outer cylinder body inside, the interlayer, inwall is provided with lifting blade and the crisscross inner barrel that is the Omasum shape of helical blade, the expansion joint that is provided with on the outer cylinder body, between the inside and outside wall of inner barrel slag input end, be provided with the sub-feed tube that distributes the quantity of slag, the cooling water pipeline system that on outer cylinder body, inner barrel interlayer, is provided with.
Double-cylinder type rotary drum cold slag machine drum body of the present invention, the outer cylinder body of employing, inner barrel structure make full use of barrel space, compact conformation.
Double-cylinder type rotary drum cold slag machine drum body of the present invention, be the inside and outside double-deck cylindrical shell of carrying the cooling warm sludge, inner barrel, outer cylinder body are sandwich type structure, and the interlayer inwall is provided with lifting blade and helical blade, and crisscross being showed the Omasum shape, play a part heat exchanger fin, heat exchange area is big, and it is big to exert oneself, and heat exchange efficiency improves, good cooling results, tapping temperature is low.
Double-cylinder type rotary drum cold slag machine drum body of the present invention, said lifting blade makes slag can lift to higher height on the one hand, has prolonged the time of contact of slag and barrel, has prolonged cool time, has increased heat exchange area simultaneously, has improved cooling capacity and effect; Played the effect of stirring on the other hand again, the relative displacement that has alleviated slag and cylindrical shell has alleviated wearing and tearing, and prolonged the service life of cylindrical shell slag input end greatly.
Double-cylinder type rotary drum cold slag machine drum body of the present invention, said sub-feed tube can distribute the quantity of slag according to the size of the film-cooled heat separately of inside and outside cylindrical shell, guarantees no matter be the warm sludge of inner barrel, and still the interior warm sludge of outer cylinder body all can satisfy the requirement of tapping temperature.
Double-cylinder type rotary drum cold slag machine drum body of the present invention, said expansion joint plays a part thermal compensation, reduces thermal stress, difference variation is had very strong adaptive capacity, so weld seam does not ftracture long service life.
Double-cylinder type rotary drum cold slag machine drum body of the present invention, when cylindrical shell rotated, the slag material was free state and rolls forward under the guide effect of flight, unimpeded when warm sludge is flowed through, and does not have strong extruding force, not stifled slag, low in energy consumption, noise is little, and so high safety is light abrasion.
Double-cylinder type rotary drum cold slag machine drum body of the present invention, its operation principle is: when cylindrical shell rotates, the high temperature furnace slag material that boiler is discharged is free state and rolls forward under the guide effect of helical blade, and carries out heat exchange with current in the interlayer, thereby makes the thermal slag cooling.Cooling water enters the outer cylinder body interlayer by the cooling water pipeline system of cylindrical shell slag output end, and forms the helical form current within it, enters inner barrel via the hydroecium of cylindrical shell slag input end.Lifting blade and helical blade that outer cylinder body, inner barrel interlayer inwall are provided with, the crisscross Omasum shape that is plays a part heat exchanger fin in the course of the work, carries out heat exchange.Inner barrel interlayer inwall and inner blade in length and breadth thereof participate in the heat exchange of its inner warm sludge, the warm sludge of slag input end is cooled off while carrying, inner barrel interlayer outer wall then participates in the heat exchange of slag in the outer cylinder body, the hot water that finishes heat exchange is back to the cooling water pipeline system conduit assembly of cylindrical shell slag output end, and flows out through outlet.
Double-cylinder type rotary drum cold slag machine drum body of the present invention proves through prototype test, because of heat exchange area increases greatly, makes warm sludge and cooling water obtain heat exchange more fully, reaches the lower target of tapping temperature, has satisfied the requirement of heavy duty boiler to slag treatment.
Double-cylinder type rotary drum cold slag machine drum body of the present invention; adopt the dry slag disposal mode; cooling water and lime-ash cool off indirectly; do not contact with water; can not destroy the physical activity of slag chemical analysis, save big water gaging consumption and expense, the lime-ash activity is maintained; utilization rate improves greatly, helps the comprehensive utilization and the environmental protection of lime-ash.
Double-cylinder type rotary drum cold slag machine drum body of the present invention, cold slag machine water inlet can connect soft water, and cooling water is behind cold slag machine, and temperature rise can reach 60 ℃～80 ℃, and water outlet can link to each other with boiler feedwater, plays economizer, improves boiler thermal output, energy savings.
In sum, double-cylinder type rotary drum cold slag machine drum body of the present invention, compact conformation, heat exchange area is big, good cooling results, it is big to exert oneself; tapping temperature is low, not stifled slag, and low in energy consumption, noise is little, high safety; there is not strong extruding force, light abrasion, long service life helps environmental protection, energy savings.
