Abstract
Disclosed is a transverse arrangement design of a cement preheater which is mainly used for preheating raw materials at the tail of a cement kiln. By the transverse arrangement design, the height of a suspension preheater system can be reduced, short circuit is prevented, and grades of cyclones can be optionally determined according to the temperature requirement of gas at the tail of the kiln. Pipelines of adjacent preheaters are designed in 'U'-shape, and the raw materials can be fed near the bottom of the 'U' shape. The transverse arrangement design can be used for building or rebuilding of the preheater system of the tail of the cement kiln.
Description
The present invention is mainly used in cement kiln end to the preheating of raw material, can heat as quick as thought cement slurry, reduces the height of suspended preheater system, and can not be subjected to the restriction of height, determines arbitrarily the progression of cyclone cylinder.
Suspended preheater is that the flue gas that raw meal powder and rotary kiln are discharged is mixed, and makes raw material be suspended in the equipment that carries out heat exchange in the hot flue gas.Therefore it has fundamentally changed the heat transfer type between air-flow and the raw meal powder, has greatly improved heat transfer area and heat transfer coefficient.
At present, the suspended preheater system adopts the five-stage whirlwind cylinder vertically to arrange usually, and this causes system height higher, has following shortcoming:
1, specification requirement is high.
2, kiln tail framework and preheater long construction period, difficulty of construction are large.
3, operating condition is poor.
4, be prone to short circuit phenomenon.In the former design, if then being prone to raw material, raw material bad dispersibility such as agglomerate etc. directly fall into the next stage cyclone cylinder.
The present invention adopts lateral arrangement with the cyclone cylinder in the suspended preheater system, but not the vertical layout that adopts at present, as shown in the figure.Main its working method is summarized as follows:
Pipeline between the adjacent preheater is the design of " U " shape, and raw material add near the bottom of " U " font, are dispelled and be brought to the next stage cyclone cylinder in pipeline under the effect of thermal current.The pipeline that is " U " shape can lengthen arbitrarily according to the preheating needs of raw material, can greatly improve like this heat exchange degree and the efficient (because the raw material heat exchange is mainly finished in pipeline) of raw material and flue gas.
The present invention has the following advantages: owing to highly reduce, infrastructure investment can reduce, and the requirement of raw material conveyor equipment also reduces.Short circuit phenomenon can not appear, available lower gas flow rate.Can according to the requirement of kiln exhaust gas temperature, determine arbitrarily the progression of cyclone cylinder.
Claims (2)
1. it is horizontally disposed that new cement preheater method for arranging, its principal character are that preheater has adopted, rather than present vertical layout;
2. the pipeline between the adjacent preheater is the connection of " U " shape.
