Description
Technical field
The utility model relates to exhaust piping technical field more particularly to a kind of kiln hood exhaust pipings.
Background technique
Cement dry method production line is current international cement industry vanguard technology, its main feature is that yield is high, heat consumption
It is low, it can effectively recycle waste gas residual heat.The grate-cooler of one of capital equipment as dry-process rotary kiln even more can largely recycle ripe
Expect waste heat, reduces energy consumption and carbon emission.Although remaining recuperation of heat ability is very high, but has quite a few thermal energy unrestrained
It has been taken that, especially since in May, 2008 trial production, grate-cooler outlet exhaust temperature maintains always 280 DEG C or more, leads for my company
It causes kiln hood cleaner failure rate high, greatly reduces dust-collecting efficiency, polluted environment, and waste partial heat energy.
My company's kiln hood cleaner is electric precipitation, and since trial operation in 2008, there are two electric fields within short 2 months
Occur because of short-circuit stop jumping accident, when stopping kiln maintenance at the end of Year 2008, discovery both inner pad is severely deformed, it is necessary to replace
Just pole plate can continue to use, after replacement, in order to improve operation rate, we increase water injector for grate-cooler, but it is useless
Temperature degree is also at 250 DEG C or more, and in order to recycle waste gas residual heat, we pass through multiple technology special meeting discussion, intends determining benefit
Domestic hot-water is provided with waste gas residual heat.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of kiln hood flue gas leading proposed
Road.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of kiln hood exhaust piping, including drum, the drum inside are equipped with exhaust piping, the drum and exhaust piping
Between weld, the both ends of the exhaust piping extend to the outside of drum, and the upper surface of the drum is welded with water inlet line, institute
The lower surface for stating drum is welded with outlet conduit, the water inlet line and outlet conduit not on the same vertical plane, it is described into
Waterpipe and outlet conduit are connected with drum.
Preferably, the diameter of the exhaust piping is 3.8M.
Preferably, the diameter of the drum is 4.2M, and the height of the drum is 2M.
Preferably, the drum is heat collector.
Compared with prior art, the utility model has the beneficial effects that
1, in the utility model, by setting drum, outlet conduit and water inlet line, the waste heat of exhaust piping can be to circle
The internal water of bucket is heated, so as to provide domestic water for people.
To sum up, the waste heat of exhaust piping can heat the water inside drum, so as to provide life for people
Water is applied flexibly, the waste heat in exhaust gas can be recycled in this way, and ensure that exhaust gas temperature is not exceeded.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of kiln hood exhaust piping structural schematic diagram；
Fig. 2 be the utility model proposes a kind of kiln hood exhaust piping hydrographic chart.
In figure: 1 drum, 2 water inlet lines, 3 exhaust pipings, 4 outlet conduits.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of kiln hood exhaust piping, including drum 1, are equipped with exhaust piping inside drum 1, drum 1 and useless
It is welded between feed channel 3, the both ends of exhaust piping 3 extend to the outside of drum 1, and the upper surface of drum 1 is welded with water inlet line
2, the lower surface of drum 1 is welded with outlet conduit 4, and water inlet line 2 and outlet conduit 4 be not on the same vertical plane, water inlet pipe
Road 2 and outlet conduit 4 are connected with drum 1.
The diameter of exhaust piping is 3.8M, and the diameter of drum 1 is 4.2M, and the height of drum 1 is 2M, and drum is heat collector.
Working principle: the waste heat of exhaust piping 3 being internally heated to drum 1, and under water inlet line 2 pacify
Two IRG65-315B are filled, the water pump of 18.5KW, one is reserve pump, another is used as normal water pump, so as to
It solves the problems, such as to heat collector moisturizing, in addition, the water heated can be delivered to office building, dining room, Zhi Gonggong by outlet conduit 4
It resides on hot duct, is that its heat supply in winter and the daily bathing of worker are used, water for bathing is discharged into sewage conduct, and heating water is recycled
It uses, the utility model can heat the waste heat of exhaust piping 3 to the water inside drum 1, so as to mention for people
For domestic water, the waste heat in exhaust gas can be recycled in this way, ensure that exhaust gas temperature is not exceeded.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
