Abstract
The utility model provides a heat insulation device which heats a blast furnace body and insulates heat for the blade furnace body at low temperature, so as to ensure that the blast furnace body is subjected to a water pressure test in a low-temperature environment of above 5 DEG C. The heat insulation device comprises a heat isolation cover which surrounds the blast furnace body and comprises a heat isolation board, and a steam outlet pipe which is communicated with a steam source is arranged in the heat isolation cover.
Description
Technical field
The utility model relates to the attemperator that blast furnace carries out the hydraulic testing under the low temperature environment.
Background technology
In the winter of the Northwest, temperature is generally at-20 ℃ to-10 ℃.In order under this low temperature environment, to carry out the hydraulic testing to blast furnace, must guarantee high furnace temperature more than 5 ℃, to prevent the water freezing in the water body of heater.How the blast furnace temperature being improved is a difficult point.
The utility model content
The purpose of this utility model provides and a kind ofly at low temperatures blast furnace is heated up, is incubated, with the true furnace body temperature attemperator that blast furnace carries out the hydraulic testing under the low temperature environment more than 5 ℃.
Blast furnace carries out the attemperator of the hydraulic testing under the low temperature environment of the present utility model, comprises the surrounded heat shield with the thermal insulation board composition of blast furnace is arranged the steam that communicates with vapour source in the inside of heat shield and goes out pipe.
Above-mentioned attemperator is provided with fire retardant canvas at the inside surface of thermal insulation board.
Above-mentioned attemperator is provided with heat-preservation cotton between thermal insulation board and fire retardant canvas.
Above-mentioned attemperator, the periphery of blast furnace is provided with the multilayer platform, is provided with 4-10 steam at every layer platform and goes out pipe.
Above-mentioned attemperator all arranges thermometer on every layer platform.
The beneficial effects of the utility model: the utility model adopts thermal insulation board surrounded blast furnace, form an inner space isolated with external environment condition, simultaneously in this inner space, feed high-temperature steam, to improve temperature, the temperature that makes the interior needs of heat shield carry out the blast furnace of the hydraulic testing can just can guarantee when like this body of heater being carried out hydraulic pressure test that water can not freeze more than 5 ℃.Fire retardant canvas has played the effect of anti-flaming thermal-insulation, has improved security and heat-insulating property.Heat-preservation cotton has further stoped scattering and disappearing of the interior heat of heat shield.The blast furnace periphery is provided with the multilayer platform, steam all is set on every layer platform pipe, has guaranteed the homogeneity of blast furnace temperature on differing heights up and down.Thermometer can when temperature is lower than 5 ℃, increase quantity of steam immediately in the real-time temperature that shows in the heat shield.
Description of drawings
Fig. 1 is the synoptic diagram that blast furnace carries out the attemperator of the hydraulic testing under the low temperature environment.
Fig. 2 is the sectional view of heat shield 1.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring under-20 ℃ of outside low temperature environments shown in Figure 1 for blast furnace carries out the attemperator that the hydraulic testing is used, comprise the surrounded heat shield 1 of blast furnace 5.Referring to Fig. 2, heat shield 1 is thermal insulation board 2, heat-preservation cotton 3, two-layer insulation canvas 4 from outside to inside successively.The periphery of blast furnace 5 is provided with multilayer platform 6 along the vertical direction, is provided with 8 steam at every layer platform and goes out pipe 7, and steam goes out pipe 7 by main steam range 9 and vapour source.Thermometer 8 all is set on every layer platform.Like this, go out pipe feeding high-temperature steam by steam and heat, guaranteed that the interior temperature of heat shield is more than 5 ℃.
Claims (5)
1. the attemperator that blast furnace carries out the hydraulic testing under the low temperature environment is characterized in that: it comprises the surrounded heat shield of forming with thermal insulation board of blast furnace, in the inside of heat shield the steam that communicates with vapour source is set and to manage.
2. attemperator as claimed in claim 1, it is characterized in that: the inside surface at thermal insulation board is provided with fire retardant canvas.
3. attemperator as claimed in claim 2 is characterized in that: be provided with heat-preservation cotton between thermal insulation board and fire retardant canvas.
4. as claim 1,2 or 3 described attemperators, it is characterized in that: the periphery of blast furnace is provided with the multilayer platform, is provided with 4-10 steam at every layer platform and goes out pipe.
5. attemperator as claimed in claim 4 is characterized in that: thermometer all is set on every layer platform.
