Description
Technical field
The utility model belongs to gas-particle two-phase field of heat exchange, relates to a kind of solid material cooling device, particularly a kind of vertical cement chamotte cooler.
Background technology
Cement clinker cooler is one of the visual plant during clinker is produced, it carry the high temperature chamotte rotary kiln is cooled fast, the effect of heat recovery and conveying.The chilling of clinker is conducive to stoping growing up of the essential mineral C3S crystal in grog, and this is conducive to the early strength improving grog, improves the grindability of grog; Make the liquid phase under molten condition be frozen into vitreum simultaneously, MgO and C3A major part is set in vitreum, be conducive to improving clinker stability and resistance to chemical attack; Reclaiming heats contained a large amount of in high temperature chamotte, for heating two, tertiary air, oven dry coal dust and cogeneration etc., is the important channel reducing sinter leaching hear rate and enterprise's production cost; After high temperature chamotte cooling, the conveying being also convenient to grog stores and process.
At present, cooling device many employings rotation drum type cooling machine of clinker or grate cooler.
Rotation drum type cooling machine is difficult to the quenching realizing clinker, and grog essential mineral likely crystal phase transition occurs, and affects clinker quality; Enter two of rotary kiln Sum decomposition stove, tertiary air temperature is too low; The cooler thermal efficiency is low, is only 35 ~ 45%, and the clinker temperature going out cooler reaches 220 DEG C.
Although grate cooler can realize the chilling of high temperature chamotte, provide two, tertiary air Wen Keda 900 ~ 1000 DEG C, the cooler thermal efficiency reaches 50 ~ 65%, goes out cooler clinker temperature lower than 65 DEG C+environment temperature.But it in use, the lingering remnants of past customs entering air has taken away a large amount of unemployed heats.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of vertical cement chamotte cooler, and it has high heat exchange efficiency and high efficiency of utilization, make to realize countercurrent flow between material and gas, quick cooling hot solid material, has energy consumption low, the feature that cost is low.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of vertical cement chamotte cooler, comprise cylindrical shell 5, cylindrical shell 5 is tightly connected by upper vertical tube 51 and lower vertical tube 52 and forms, connect charging aperture 2 above upper vertical tube 51, upper vertical tube 51 inside arranges disintegrating machine 7, arranges unloader 11 in lower vertical tube 52, discharge duct 14 is arranged at the bottom of lower vertical tube 52, described unloader 11 is driven by transmission mechanism 12, and the fixed axis of transmission mechanism 12 is hollow blast pipe 13, and blast pipe 13 communicates with the inside of lower vertical tube 52.
Wherein said disintegrating machine 7 can be kibbler roll or tower-type crusher, and kibbler roll can arrange central tube 8 at roller inner.
Unloader 11 is to be tower unloader or vibration unloader, and transmission mechanism 12 can select reductor.
The shape of cross section of cylindrical shell 5 can be multiple, such as, go up vertical tube 51 cross section for circular or rectangle and also can be circle or rectangle with vertical tube 52 cross section at present.
The utility model compared with prior art, has the following advantages:
One) realize countercurrent flow between material and gas, heat exchange is abundant, and heat exchange efficiency is high, and heat utilization ratio is high;
Two) required cooling air quantity is little, effectively can reduce energy consumption;
Three) reduced investment, floor space are little, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, the charging aperture of the utility model cooler and cement rotary kiln, and upper vertical tube connects kiln head cover, and in figure, arrow R represents hot blast, and L represents cold wind, the direction of arrow and wind direction.
Fig. 2 is structural representation side view of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further details.
As depicted in figs. 1 and 2, the utility model is a kind of vertical cement chamotte cooler, comprise cylindrical shell 5, cylindrical shell 5 is tightly connected by upper vertical tube 51 and lower vertical tube 52 and forms, charging aperture 2 is connect above upper vertical tube 51, the i.e. rotary kiln in cement plant, upper vertical tube 51 is also connected to kiln head cover 17 in addition, upper vertical tube 51 inside arranges disintegrating machine 7, space above disintegrating machine 7 is quench zone 6, in lower vertical tube 52, unloader 11 is set, discharge duct 14 is arranged at the bottom of lower vertical tube 52, space between unloader 11 and disintegrating machine 7 is cooling zone 10, unloader 11 is driven by transmission mechanism 12, transmission mechanism 12 is reductor, its fixed axis is hollow blast pipe 13, blast pipe 13 communicates with the inside of lower vertical tube 52.
Disintegrating machine 7 can be kibbler roll or tower-type crusher, itself hollow of tower-type crusher, and kibbler roll inside can arrange central tube 8, and below arranges cooling tube 9.
Unloader 11 is can be tower unloader or vibration unloader.
During work, the high temperature chamotte 4 going out rotary kiln enters into quench zone 6 from charging aperture 2, because the temperature of high temperature chamotte 4 and the temperature of quench zone 6 and normal temperature differ greatly, therefore high temperature chamotte 4 realizes preliminary quenching cooling in quench zone 6, then be moved into cooling zone 10 under machine 7 fragmentation that is broken is backward, under the effect of transmission mechanism 12, grog 15 after cooling drawn off by discharge duct 14 by the unloader 11 bottom lower vertical tube 52 after cooling.
While charging, an air cooling air is upwards flowed by the comb hole of blast pipe 13 through unloader 11, behind cooling zone 10 with the abundant heat exchange of grog, enters quench zone 6 by the space between breaker roll.Another part cooling-air upwards flows through cooling tube 9, first cools disintegrating machine 7, then enters cooling zone 10.
Air or water can be passed into, in order to cooled roller in the central tube 8 of disintegrating machine 7.After entering high temperature chamotte 4 heat exchange near the air of cooling zone 10 and disintegrating machine 7, a part supplies as rotary kiln Secondary Air 3 the coal dust firing use that coal injection pipe 16 sprays into, another part as tertiary air 18 through tertiary-air pipe 1 for dore furnace coal dust firing.
In the utility model, the cross sectional shape of upper vertical tube 51 and lower vertical tube 52 can design with on-site actual situations, and the cross sectional shape of upper vertical tube 51 and lower vertical tube 52 can consistent also can be inconsistent, such as, the cross sectional shape of upper vertical tube 51 is circular or rectangle, lower vertical tube 52 also can be circle or rectangle.
