The technical scheme of the utility model it is high about 10% to reduce the pre -heater, consequently can practice thrift pre -heater frame investment about 12%, the pre -heater is separately arranged with the dore furnace, separately construction, can show about saving construction period 15 sky. Arrange separately with pre -heater and dore furnace that the overall arrangement is more reasonable, annual operating repair is more convenient, practices thrift maintenance time.
Description
Technical field
This new technique belongs to field of cement production equipment, and more particularly to a kind of transformation for cement clinker production line is new
System.
Background technology
It is with deepening continuously that Industry Structure is adjusted, energy-saving to have become the huge of every profession and trade survival and development and push away
Power.Every profession and trade all suffers from the pressure of the market competition and national industrial policies adjustment, only constantly carries out technological innovation, improves
Product quality, reducing energy consumption, improve product competitiveness in the market, and Cai Nengshi enterprises obtain the permanent survival and development.Cement kiln end
Thus the transformation of technology is also produced with innovation.The arrangement of existing kiln tail preheater and dore furnace, is roughly divided into two classes：One
It is that preheater is arranged together with dore furnace, that what is leaned on each other is close, is arranged in a framework, this kind of arrangement causes
Preheater bottom is too crowded, and Maintenance and Repair are inconvenient, and upper space is too abundant, while structural steel consumption is more.Two
It is that dore furnace is arranged for off-line type, hang over outside dore furnace outside preheater framework, the program is higher to Structural Design Requirement, and
Decomposing force arranges that operation operation is cumbersome, and heat consumption is higher offline.
Utility model content
The purpose of this utility model is the defect for prior art, there is provided a kind of cement kiln production line new system.
To achieve these goals, this utility model is using technical scheme once：A kind of cement kiln production line new system, bag
Include：Grate-cooler, rotary kiln, dore furnace, Pyatyi cyclones in series, preheater framework and dore furnace framework；It is wherein described pre-
Hot device framework, dore furnace framework are respectively as Pyatyi cyclones in series and the support frame of dore furnace, the Pyatyi series connection
Cyclone separator is from top to bottom respectively the first to level V cyclone separator, and wherein fourth stage cyclone separating device of dust outlet connects
Connect the solid inlet of dore furnace, the flue gas discharge opening connection level V cyclone inlet of dore furnace, level V cyclonic separation
Device dust export connects rotary kiln smoke-box, and the rear portion of rotary kiln is provided with grate-cooler.
Preheater framework and dore furnace framework are separated from each other or share one side or side framework.
The preheater framework is higher than dore furnace framework.
The dore furnace is directly seated on rotary kiln smoke-box.
The kiln gas of rotary kiln smoke-box and the tertiary air of grate-cooler enter dore furnace.
The technical solution of the utility model can reduce preheater height about 10%, therefore can save the throwing of preheater framework
Money about 12%；Preheater is arranged apart with dore furnace, separate construction, can significantly save the construction period 15 days or so.By preheater
Arranged apart with dore furnace, layout is more reasonable, and annual Maintenance and Repair are convenient, saves maintenance time.
Description of the drawings
Fig. 1 is the structural representation of this utility model cement kiln production line.
Specific embodiment
With reference to specific embodiments and the drawings, the present invention is described further.
Cement kiln production line new system, including：Grate-cooler 1, rotary kiln 2, rotary kiln pier 3, dore furnace 4, dore furnace framework
5th, Pyatyi cyclones in series 6, preheater framework 7 and high-temperature blower 8.Rotary kiln bottom is supported for rotary kiln pier 3.
Pyatyi cyclones in series is from top to bottom respectively the first to level V cyclone separator (C1 to C5), wherein the
Tetra-cyclone C4 dust exports connect the solid inlet of dore furnace, the flue gas discharge opening connection level V whirlwind of dore furnace
Separator C5 entrances, level V cyclone separating device of dust outlet connection smoke-box, material enter rotary kiln by smoke-box, rotary kiln
Rear portion is provided with grate-cooler, and dore furnace is directly seated on rotary kiln smoke-box, and the kiln gas and tertiary air of rotary kiln
Into dore furnace.
Support frame of the preheater framework as Pyatyi cyclones in series, support of the dore furnace framework as dore furnace
Framework, preheater framework and dore furnace framework are separated from each other, or two frameworks share organ timbering, but preheat in plan view
Device and dore furnace are still arranged in different frameworks.
Technical process and material flow are as follows：
Material flow：Raw material are promoted to feeding at the blast pipe of the C1 of cyclone separator 6, enter C1, Jing with high-temperature gas
Gas solid separation enters next stage airduct from C1 bottoms, and with thermal current together into the C2 of next stage cyclone separator 6, before repeating
The program in face, until dore furnace 4.C5 is entered after decomposing in dore furnace 4, Jing C5 select powder to enter kiln.
Flue gas flow:Kiln gas and tertiary air enter dore furnace 4, and Jing hot air ducts enter the C5 of cyclone separator 6, from C5 tops
Air-out enters the C4 of cyclone separator 6, with this sequentially until out entering high-temperature blower 8 from the C1 of cyclone separator 8.
The above, is only preferred embodiment of the present utility model, not does any type of to this utility model
Limit.It is every to become according to technology of the present utility model and the substantive any simple modification made to above example of method, equivalent
Change and modification, still fall within the range of technology of the present utility model and method scheme.
