22 are wound in coiling fixing piece 211, and adding thermal resistance 23 is fixed in the inner side of fixed frame 21.
Wind deflector 211 determines the fixation and trend when heating cable 22 is wound so that distance is suitable between cable often encloses,
Heating effect is more preferable.
Heating 23 two kinds of heaters of cable 22 and adding thermal resistance can take into account the demand of quick heating and continuous heating, reach
More preferable heating effect.
The maximum temperature of mineral insulated cable long-term work is 600 DEG C, has good oxidation-resistant corrosion-resistant performance.Pass through
Heating cable jacket material uses oxidation-resistant corrosion-resistant alloy so that heating cable has oxidation-resistant corrosion-resistant performance, closes at the same time
Golden material make it that heating the heat that cable produces effectively exports.
In the present embodiment, 122 outer shape of construction section is reducer pipe.Reducer pipe by fill in pipeline tapping to be heated into
Row air-supply.The sectional area of reducer pipe is gradually reduced from rear end to front end, improves the speed that air reaches thermal region to be added, and reduction is sent
Thermal losses during wind.
In the present embodiment, using the connection that is screwed between heating unit casing 11 and the air port reducing casing tube 12；Institute
State and be fixedly connected between heating unit casing 11 and the air-supply arrangement 3 using bolt or buckle.
By using the connection that is screwed between heating unit casing 11 and air port reducing casing tube 12 so that between the two may be used
To dismantle according to demand, while the connection that is screwed could alternatively be buckle and be fixedly connected；Pass through heating unit casing 11 and institute
State and be fixed by bolts connection between air-supply arrangement 3 so that can dismantle according to demand between the two, while bolt is fixedly connected
Buckle is could alternatively be to be fixedly connected.In the above manner, so that all can mutually be dismantled between each critical piece, convenient split is transported
Defeated or quick-replaceable reparation when having partial destruction.
