Abstract
A pipeline for transmitting high-temperature flue gas comprises a pipeline body (1) for transmitting high-temperature gas, an inner coating (2) and an outer coating (3), wherein the inner coating (2) is arranged on the inner side face and used for preventing dust of the high-temperature gas from abrading the pipeline body (1), and the outer coating (3) is arranged on the outer side face and used for preventing heat energy of the high-temperature gas from dissipating. When the dust of the high-temperature flue gas gathers, grooves are not generated on the inner surface of the pipeline body (1) under the action of the inner coating (2), and meanwhile, the loss of heat of the high-temperature flue gas can be avoided under the action of the outer coating (3), and therefore transmitting speed of the high-temperature flue gas can be ensured, and the loss of the heat can be avoided.
Description
Technical field
The utility model relates to a kind of conveyance conduit, especially a kind of conveyance conduit that is used for high-temperature flue gas.
Background technique
The a large amount of high-temperature gases of industrial normal needs are as working medium, are used for drying, heating finished product, because the gas flow that needs is bigger, through setting up the source of the gas output unit, as hot blast stove with being everlasting the thermal source demand; But problem because of allocation of production, thermal source supply equipment such as hot blast stove etc. can not be in the same localities fully with terminal thermal source party in request, in order to continue to provide high-temperature gas, therefore the conveyance conduit that is used for high-temperature flue gas is an important defeated thermic devices, existing high-temperature flue gas conveyance conduit case is seldom perhaps used instead and is carried other media to substitute flue gas.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model provides a kind of conveyance conduit that is used for high-temperature flue gas, has therefore guaranteed the transporting velocity of high-temperature flue gas, has avoided the loss of heat.
For achieving the above object, the technological scheme that the utility model is taked is: the dust that includes the pipeline body that is used to carry high-temperature gas, is arranged on the inner side surface and is used to prevent high-temperature gas to pipeline body produce wearing and tearing undercoating, be arranged on the outer side surface and be used to prevent the external coating that the heat energy of high-temperature gas distributes.
When high-temperature flue gas in conveyance conduit, carry at a distance, thereby heat energy is transported in the terminal thermal source, owing to designed pipeline body, undercoating and external coating, when the dust accumulation of high-temperature flue gas, under internally coated effect, groove does not appear in the internal surface that has guaranteed pipeline body, under the effect of external coating, prevents the high-temperature flue gas heat loss simultaneously, therefore guarantee the transporting velocity of high-temperature flue gas, avoided the loss of heat.
The utility model has designed, and also includes shell, and the inner side surface of pipeline body is provided with undercoating, and the outer side surface of pipeline body is provided with external coating, and the outer side surface of external coating is provided with shell.
The utility model has designed, undercoating be set to by aluminium oxide ceramics constitute the layer body.
The utility model has designed, external coating be set to by glass fibre constitute the layer body.
The utility model has designed, shell be set to by polystyrene constitute the layer body.
Description of drawings
Accompanying drawing is a schematic representation of the present utility model.
Embodiment
Accompanying drawing is an embodiment of the present utility model, specify present embodiment in conjunction with the accompanying drawings, include pipeline body 1, undercoating 2, external coating 3 and shell 4, the inner side surface of pipeline body 1 is provided with undercoating 2, the outer side surface of pipeline body 1 is provided with external coating 3, and the outer side surface of external coating 3 is provided with shell 4.
In the present embodiment, undercoating 2 be set to by aluminium oxide ceramics constitute the layer body.
In the present embodiment, external coating 3 be set to by glass fibre constitute the layer body.
In the present embodiment, shell 4 be set to by polystyrene constitute the layer body.
When high-temperature flue gas in conveyance conduit; when carrying; undercoating 2 plays high temperature resistant and the abrasionproof effect, and external coating 3 plays the insulation heat-blocking action, and shell 4 plays a protective role; when carrying more than 600 ℃ high-temperature flue gas; pipeline body 1 is the 1Cr18Ni9Ti Stainless Steel Tube, and when carrying more than 750 ℃ high-temperature flue gas, pipeline body 1 is the Cr25Ni20 Stainless Steel Tube; when carrying high-temperature flue gas below 600 ℃, pipeline body 1 is No. 20 seamless steel pipes.
The characteristics of the utlity model has down:
1, owing to designed pipeline body 1, undercoating 2 and external coating 3, when the dust accumulation of high-temperature flue gas, under the effect of undercoating 2, groove does not appear in the internal surface that has guaranteed pipeline body 1, simultaneously under the effect of external coating 3, prevent the high-temperature flue gas heat loss, therefore guaranteed the transporting velocity of high-temperature flue gas, avoided the loss of heat.
2, owing to designed undercoating 2,, guaranteed the roughness of internal surface, alleviated the influence of flowing high-temperature flue gas by aluminium oxide ceramics.
3, owing to designed external coating 3,, guaranteed intensity, improved effect of heat insulation by glass fibre.
In being used for the conveyance conduit technical field of high-temperature flue gas; The dust that everyly includes the pipeline body 1 that is used to carry high-temperature gas, is arranged on the inner side surface and is used to prevent high-temperature gas to pipeline body 1 produce wearing and tearing undercoating 2, be arranged on the outer side surface and the technology contents that is used to prevent the external coating 3 that the heat energy of high-temperature gas distributes all in protection domain of the present utility model.
