Description
Technical field：
Cement clinker production line field is the utility model is related to, it is integrated online to relate generally to a kind of cement kiln waste heat recovery
System.
Background technology：
Existing cement clinker production line system, as shown in figures 1 and 3, generally comprise pre-heating system 1, kiln tail humidification
Cooling device 2, kiln tail waste heat boiler 3, high-temperature blower 4, firing system 5, grate-cooler 6, kiln hood waste heat boiler 7, aerial cooler
8th, bag filter 9, kiln head exhaust fan 10, chimney 11.Wherein kiln exit gas flow is that high-temperature flue gas picks out from pre-heating system
After respectively enter kiln tail waste heat boiler and humidification cooling device, kiln tail waste heat boiler be humidified cooling device be in parallel standby each other
Relation, the flue gas after kiln tail waste heat boiler or humidification cooling device desuperheat are sent to kiln tail gas system into high-temperature blower；Kiln
Head flue gas flow is that grate-cooler high-temperature flue gas is connected by different flues with kiln hood waste heat boiler and air-cooling apparatus, kiln
Head boiler and aerial cooler are standbies in parallel, high-temperature flue gas after kiln hood waste heat boiler or aerial cooler cool down after again
Bag filter is passed through, is discharged through kiln head exhaust fan and chimney.
In recent years, reaching its maturity with domestic cogeneration equipment and managerial skills, the stability of afterheat generating system
There is the raising of matter with reliability, therefore in the supporting clinker production line of afterheat generating system, humidification cooling device 2,
Aerial cooler 8 is substantially at idle state, has both wasted investment, while also increases the maintenance dynamics of equipment.
Utility model content：
A kind of the defects of the utility model purpose is exactly to make up prior art, there is provided cement kiln waste heat recovery online one
Body system, to solve the problems, such as that flue gas cooling device has idle waste in prior art cement producing line.
The utility model is achieved through the following technical solutions：
A kind of online integral system of cement kiln waste heat recovery, include firing system, pre-heating system, kiln tail waste heat pot
Stove, high-temperature blower, grate-cooler, kiln hood waste heat pot, bag collector, a high-temperature flue gas part is through kiln tail caused by the firing system
Portion is entered in pre-heating system, subsequently into kiln tail waste heat boiler, is most sent to kiln tail gas system through high-temperature blower afterwards, another
Part is worked by the grate-cooler of kiln hood position and is passed into high-temperature flue gas in kiln hood waste heat boiler by flue, its high temperature
Flue gas is passed through bag filter again after kiln hood waste heat boiler, is discharged through kiln head exhaust fan and chimney.
Three are set on described grate-cooler respectively and takes air port, one of them takes air port to be located at grate-cooler front portion, another
Air port is taken to be located in the middle part of grate-cooler, the 3rd takes air port to be located at cooling drive end unit, is controllable by the cigarette air valve group on airduct
EAT of the system into kiln hood waste heat boiler.
Its principle is：Because kiln tail gas system does not have particular/special requirement to exhaust gas temperature, therefore in new technological process on the one hand
Cancel humidification cooling device, flue gas enters high-temperature blower after directly being cooled down by preheater to kiln tail waste heat boiler, delivers to kiln tail and give up
Gas system, not pipe boiler whether run, go out preheater high-temperature flue gas and enter high-temperature blower directly after boiler cools down, deliver to kiln tail
Waste gas system.On the other hand aerial cooler is cancelled, grate-cooler flue gas directly gathers dust after kiln hood waste heat boiler cools down into bag
Device, discharged by kiln head exhaust fan and chimney.For kiln hood system smoke discharging temperature requirement, grate-cooler combination takes wind to design, and passes through
Cigarette air valve group on airduct is the controllable EAT into kiln hood waste heat boiler, so as to ensure kiln hood system under various operating modes
The exhaust gas temperature of system meets to require.
The utility model has the advantages that：
The utility model cancels flue gas cooling device on the basis of original cement clinker production line（Including aerial cooler,
Be humidified cooling device）, and with kiln hood, kiln tail waste heat boiler directly as the flue gas heat recovery in cement clinker production line and cooling
Equipment, melt waste heat boiler for the online integrated part produced of clinker, rather than optional equipment.It is of the present utility model
Use, saved construction investment, simplified technique and management process, improve production efficiency, therefore the utility model has very
Good market popularization value.
Brief description of the drawings：
Fig. 1 is existing kiln tail process chart.
Fig. 2 is the utility model kiln tail process chart.
Fig. 3 is existing kiln hood process chart.
Fig. 4 is the utility model kiln hood process chart.
Fig. 5 is that grate-cooler combination smoke takes wind design diagram.
Fig. 6 is overall structure diagram of the present utility model.
Embodiment：
Referring to accompanying drawing.
A kind of online integral system of cement kiln waste heat recovery, includes firing system 5, pre-heating system 1, kiln tail waste heat
Boiler 3, high-temperature blower 4, grate-cooler 6, kiln hood waste heat pot 7, bag collector 9, high-temperature flue gas one caused by the firing system 5
Lease making kiln tail portion is entered in pre-heating system 1, subsequently into kiln tail waste heat boiler 3, is most sent to kiln tail through high-temperature blower 4 afterwards and is given up
Gas system, another part are worked by the grate-cooler 6 of kiln hood position high-temperature flue gas being passed into kiln hood waste heat by flue
In boiler 7, its high-temperature flue gas is passed through bag filter 9 again after kiln hood waste heat boiler 7, through kiln head exhaust fan 10 and the row of chimney 11
Go out.
Three are set to take air port respectively on described grate-cooler 6, one of them takes air port 01 to be located at grate-cooler front portion, another
Individual to take air port 02 to be located in the middle part of grate-cooler, the 3rd takes air port 03 to be located at the afterbody of grate-cooler 6, passes through the cigarette air valve group on airduct
That is the controllable EAT into kiln hood waste heat boiler.
