Description
Technical field
The present invention relates to a kind of superhigh temperature resistant smoke pipelines, solve the resistance to height that 1400 DEG C to 1600 DEG C high-temperature gases pass through
The problems such as technology of warm flue is few, effect is poor, the lost height of the energy, the service life is short, high temperature is dangerous.Suitable for waste incinerator
And the various facilities for having high-temperature flue gas.
Background technique
High temperature resistant flue due to there is the high-temperature flue gas of certain speed to pass through, and has corrosivity, presently mainly adopts
The flue being made with the refractory materials such as steel resistant to high temperature or stainless steel, ceramics wraps up heat preservation in pipeline external again
Heat-barrier material has certain heat insulation effect, but (especially flue-gas temperature is more than 1000 DEG C to unbearable prolonged high temperature
When) flue gas passes through, therefore, substantially flue-gas temperature is below 1000 DEG C, otherwise, can make pipeline fusing, fall off and scrap, simultaneously
Also scatter and disappear thermal energy, and service life is short.
Summary of the invention
A kind of high temperature cigarette the object of the present invention is to provide superhigh temperature resistant flue, especially temperature at 1400 DEG C or so
Feed channel.Above-mentioned purpose is realized by following technical scheme: a kind of superhigh temperature resistant flue, and composition includes: resistance to super
High-temperature pipe layer, thermostable heat-isolating layer, flexible heat-insulating layer, structure sheaf, the superhigh temperature resistant pipe layers outer surface package
Thermostable heat-isolating layer, thermostable heat-isolating layer appearance wrap up flexible heat-insulating layer, and flexible heat-insulating layer appearance and structure sheaf are close
Real connection and the multi-layer piping formed, i.e. superhigh temperature resistant flue.
The resistance to overtemperature pipe layers are the pipeline that high-temperature flue gas passes through, and the main material of pipe layers is the molybdenum of superhigh temperature resistant
Carbon silicon is uniformly mixed by certain proportion, after the molding of scheduled design mold, then calcine, in 1600 DEG C of high temperature
Under will not melt or fall off.To solve the technical problem of high-temperature flue gas pipeline non-refractory.
The high temperature insulating insulating layer, is wrapped around the layer of material of superhigh temperature resistant pipe layers outer surface, mainly by
Fire resisting brick masonry forms, and fully wrapped around superhigh temperature resistant pipe layers prevent heat energy dissipation, and play heat-blocking action, effectively solves
Certainly heat-insulated and heat preservation problem.
The flexible heat-insulating layer, to make heat-insulated, heat insulation effect more preferably, between structure sheaf and high temperature insulating insulating layer,
Increase one layer of heat preservation layer again, flexible heat-insulating layer carries out dense packing effect using elastic material, has not only facilitated production, but also increase heat insulation effect.
More importantly structure sheaf is effectively protected because of temperature change.
The structure sheaf is the structural support of entire pipeline, and fixed by structure sheaf.It is required that structure sheaf has
There is certain structural capacity, carries the support of resistance to overtemperature pipe layers, high temperature insulating insulating layer enough, can be steel, be also possible to
Other materials.
The superhigh temperature resistant flue, is traditionally arranged to be length 4m hereinafter, too long, manufacture difficulty is too big.
The superhigh temperature resistant flue can be typically provided with ring flange at both ends, can also be in favor of pipeline connection
It is connected with other methods.
Effect of the invention:
1, the service life for increasing substantially high-temperature flue gas pipeline, due to using the ultra-high temperature resistant material conduct of molybdenum carbon silicon production
Exhaust gases passes will not generate fusing because of high temperature, fall off.
2, thermal loss is considerably reduced, due to increasing high-temperature-resistant thermal-insulation thermal insulation layer and elastic heat preserving layer, in pipeline
When inside passing through 1500 DEG C or so high temperature, in structure sheaf, i.e. the temperature of pipeline appearance is lower than 50 DEG C.
Detailed description of the invention
Fig. 1 is main view
Fig. 2 is top view
Fig. 3 is A-A sectional view
1 is superhigh temperature resistant pipe layers, and 2 be thermostable heat-isolating layer, and 3 be flexible heat-insulating layer, and 4 be structure sheaf.
Specific embodiment
It is explained by taking circular pipe as an example: according to the exhaust gas volumn passed through, using ∮ 300mm as the superhigh temperature resistant fume pipe of internal diameter
The size in road, other each layers designs as follows:
Superhigh temperature resistant pipe layers are the wall thickness of 30mm, and thermostable heat-isolating layer is 240mm thick, and flexible heat-insulating layer is 50mm thick,
Structure sheaf is 5mm thick, then the outer diameter of this pipeline is ∮ 950mm.
Superhigh temperature resistant pipe layers are that molybdenum carbon silicon is mixed in a certain ratio, and are outer diameter by ∮ 300mm internal diameter and ∮ 360mm, are about
1000mm, the concaveconvex structure that both ends port is provided with convenient for connection, is formed using Mold Making, and through calcining.
Thermostable heat-isolating layer uses Mo Naishi brick, is constructed by the way of masonry.
Flexible heat-insulating layer uses refractory wool, appropriate to pressurize using filling, is allowed to keep closely knit connection with structure sheaf.
Structure sheaf uses 5mm thickness steel pipe.That is internal diameter ∮ 940mm, outer diameter ∮ 950mm, are usually made using steel plate, and length is
3m。
Specific production method: taking an outer diameter ∮ 950mm, the steel pipe of thick 5mm, the as structure sheaf 4, and level is fixed
It places, at one end the refractory wool of one layer of 5mm thickness of inner cavity lower part laying, i.e. the flexible heat-insulating layer 3, in high-temperature-resistant thermal-insulation cotton
The upper Mo Naishi brick for building a treaty 1000mm long, i.e. thermostable heat-isolating layer 2, build thickness 240mm, then in Mo Naishi brick
On put superhigh temperature resistant pipe layers 1 well;Mo Naishi brick and filling high-temperature-resistant layer cotton are according to said method gradually built, the system of one end is completed
Make.
Further, pipeline is stood vertically, one end that production face is completed is bottom, by first to connecting superhigh temperature resistant
Pipe layers, then build Mo Naishi brick, refill heat-preservation cotton, in this order, by the size of Mo Naishi brick, successively build, from lower
On complete.
Effect of the invention:
1, the service life for increasing substantially high-temperature flue gas pipeline, due to using the ultra-high temperature resistant material conduct of molybdenum carbon silicon production
Exhaust gases passes will not generate fusing because of high temperature, fall off.
2, thermal loss is considerably reduced, due to increasing high-temperature-resistant thermal-insulation thermal insulation layer and elastic heat preserving layer, makes the guarantor of pipeline
Temp effect is more obvious, and for inner cavity temperature at 1000 DEG C or more, the temperature of outer surface is lower than 40 DEG C.
