Embodiment 1
[0039] figure 1 Schematically provides a partial structure cross-sectional diagram of the tubular heating furnace of the embodiment of the present invention, as figure 1 Shown, described tubular heating furnace comprises:
[0040] Insulation layer 41, the insulation layer 41 encloses the furnace, and the structure and material of the insulation layer 41 are prior art in the art, and will not be repeated here.
[0041] A refractory fiber furnace lining 31, the refractory fiber furnace lining 31 is provided on at least part of the insulation layer 41;
[0042] Accommodating space, the accommodating space is arranged on the refractory fiber furnace lining 31, and its specific shape matches the installation end of the black body element 11; preferably, the accommodating space is a hole or a groove, such as a blind hole, a cylindrical hole, a prism-shaped A hole, an annular groove; in order to install the blackbody element more reliably, preferably, the depth of the accommodating...
Embodiment 2
[0056] An application example of the tubular heating furnace and the energy-saving method according to Embodiment 1 of the present invention.
[0057] image 3 Schematically provides a partial structure cross-sectional diagram of the tubular heating furnace of the embodiment of the present invention, as image 3 As shown, the blackbody element 11 is a cylindrical member with two ends open, and one end also has a flange along the radial direction. Utilize tool on the refractory fiber furnace lining 31 to open the blind hole that matches with the end of the flange of the black body element 11, the depth is 20mm, the aperture in the depth of the blind hole matches the outer diameter of the flange, and the aperture in the shallow part matches the outer diameter of the flange. Matches outside diameters of cylindrical parts and cleans debris from blind holes. Before embedding the blackbody element 11 , spray reinforcement to the refractory fiber lining 31 in and around the blind h...
Embodiment 3
[0059] An application example of the tubular heating furnace and the energy-saving method according to Embodiment 1 of the present invention in an ethylene cracking furnace.
[0060] Figure 4 Schematically provides a partial structure cross-sectional diagram of the tubular heating furnace of the embodiment of the present invention, as Figure 4 As shown, the black body element 11 is a cylindrical part with both ends open, use a tool to open an annular groove matching the black body element 11 on the refractory fiber lining 31, the depth is 10mm, and clean the debris in the annular groove. Before embedding the blackbody element 11 , spray a strengthening agent to the refractory fiber lining 31 in and around the annular groove, so as to increase the hardness of the lining. Then apply high-temperature adhesive 21 on one end of many blackbody elements (such as 10,000), and insert one end of the blackbody element with adhesive 21 into the annular groove, thereby reliably fixing t...
