Abstract
A kind of kiln tail smoke-box channel design, belong to field of cement production equipment, including dore furnace cone, necking section, transition and conversion section, smoke-box expansion joint, smoke-box；Described dore furnace cone is arranged on the bottom of dore furnace, and its top is connected with decomposing body of heater, and bottom is connected with necking section；Described necking section is arranged on dore furnace cone lower end；Described transition and conversion section is arranged between necking section and smoke-box expansion joint, and its upper end is connected with necking section, and lower end is connected with smoke-box expansion joint；Described smoke-box expansion joint is arranged between transition and conversion section and smoke-box outlet, and its both ends connects with transition and conversion section and smoke-box outlet respectively；Described smoke-box is arranged on the bottom of smoke-box expansion joint, and its outlet is connected with smoke-box expansion joint；With the flowing resistance that can reduce smoke-box passage, expand the ventilation-sectional area of passage, using electricity wisely, it is possible to increase the characteristics of the yield of rotary kiln.
Description
Technical field
The invention belongs to field of cement production equipment, more particularly to one kind is arranged on cement burning rotary kiln afterbody and smoke-box
Between the vent passages that connect.
Background technology
Kiln tail smoke-box passage, it is the ventilation that is set between cement burning rotary kiln and smoke-box in cement production process
Passage, the wind in rotary kiln are sent into by blower fan from kiln hood, mix it is coal-fired form hot blast, the cement slurry in rotary kiln is forged
Burn, hot blast reaches smoke-box by vent passages from kiln tail and then reaches dore furnace, therefore, the ventilation in rotary kiln, determines
Fire coal, in identical ventilation, can determine flowing resistance with the amount of completely burned；Existing kiln tail smoke-box passage, mostly
It is arranged on using passage between smoke-box and dore furnace, outer layer has housing, internally using refractory material is poured, forms passage, by
It is square in the outlet of smoke-box, and dore furnace centrum is circular arc interface, therefore just need between smoke-box and dore furnace using side
It is excessive to round section, therefore often channel wall thickness is excessively done net sectional area that is thicker, therefore reducing passage by these,
Reduce ventilation, hinder kiln hood coal dosage, add kiln ventilation resistance, while add blower fan power consumption, finally lead
The yield of rotary kiln is caused to be difficult to improve.
The content of the invention
For above mentioned problem existing for existing kiln tail smoke-box passage, the present invention proposes a kind of kiln tail smoke-box channel design,
It is characterized in that：Including dore furnace cone, necking section, transition and conversion section, smoke-box expansion joint, smoke-box；Described dore furnace cone
The bottom of dore furnace is arranged on, its top is connected with decomposing body of heater, and bottom is connected with necking section；Described necking section is arranged on point
Stove cone lower end is solved, its top is connected with dore furnace cone, and bottom is connected with transition and conversion section；Described necking section inner chamber is straight
Cartridge type；Described transition and conversion section is arranged between necking section and smoke-box expansion joint, and its upper end is connected with necking section, lower end and cigarette
Room expansion joint connection；The lower end section of described transition and conversion section is square, is matched with smoke-box outlet shape and size；
The upper end section of described transition and conversion section is circle, is matched with necking section shape and size；Described transition and conversion section
It is abnormally-structured for tubular, i.e., be from lower end to upper end formed from square-section to circular cross-section by curve smoothing transition it is hollow
Body；Described smoke-box expansion joint be arranged on transition and conversion section and smoke-box outlet between, its both ends respectively with transition and conversion Duan Yuyan
Room outlet connection；Described smoke-box is arranged on the bottom of smoke-box expansion joint, and its outlet is connected with smoke-box expansion joint.
Beneficial effect
The beneficial effects of the present invention are, the flowing resistance of smoke-box passage can be reduced, expands the ventilation-sectional area of passage,
Using electricity wisely, it is possible to increase the yield of rotary kiln.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention
1. dore furnace cone, 2. necking sections, 3. transition and conversion sections, 4. smoke-box expansion joints, 5. smoke-boxes.
Embodiment
In order to further illustrate technical scheme, in conjunction with the embodiment of the brief description of the drawings present invention；Such as
Fig. 1, wide 2500 millimeters using the outlet of smoke-box 5 to be long 2500 millimeters in this example, a diameter of 2300 milli of dore furnace cone 1
Exemplified by rice；Height from necking section 2 is 650 millimeters, 2300 millimeters of diameter, and cast protective layer thickness is 250 millimeters, will thereon
End is connected with dore furnace cone 1, and lower end is connected with transition and conversion section 3；Height from transition and conversion section 3 is 1000 millimeters, on
Mouthful a diameter of 2300 millimeters, lower section is long 2500 millimeters, wide 2500 millimeters square, and cast wall thickness is 250 millimeters, middle part
Template is made using steel plate, poured into a mould, its upper end is connected with necking section 2, lower end is connected with smoke-box expansion joint 4；From this
The smoke-box expansion joint of industry universal is installed in smoke-box 5 and exported between transition and conversion section 4 as smoke-box expansion joint 4；With regard to complete
Into the implementation of the present invention；Because employ two segment type transition so that smoke-box passage minimum ventilation-sectional area can reach 2000
Millimeter X2000 millimeters；According to existing channel design, it is merely able to reach 1700 millimeters of X1700 millimeters, considerably increases smoke-box and lead to
The draught area in road, reduces flowing resistance, provides possibility to the yield for improving rotary kiln, while reduce kiln ventilation
Resistance so that the load of main air blower reduces, and saves electric energy.
