Embodiment 1

[0037] figure 1 Schematically provides a partial structural diagram of the energy-saving kiln of the embodiment of the present invention, as figure 1 As shown, the energy-saving kiln includes:

[0038] The kiln wall 41, which encloses a hearth, and the structure and material of the kiln wall 41 are prior art in the art, and will not be repeated here.

[0039] A refractory fiber lining 31, the refractory fiber lining 31 is provided on at least part of the kiln wall 41;

[0040] 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 space is 5-80mm.

[0041] Black body element 11, the interior of the black body e...

Embodiment 2

[0052] An application example of the energy-saving kiln and the energy-saving method for the kiln according to Embodiment 1 of the present invention.

[0053] image 3 Schematically provides a partial structural diagram of the energy-saving kiln of the embodiment of the present invention, as image 3As shown, the blackbody element 11 is a cylindrical member with two ends open, and one end also has a radially annular extension. Utilize tool on the refractory fiber furnace lining 31 to open a blind hole that matches the end of the black body element 11 that has an extension, and the depth is 20mm. 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 hole, so as to increase the hardness of the lining. Then apply high-temperature adhesive 21 on one end of a large number of blackbody elements 11 (for example, 2000) with extension...

Embodiment 3

[0056] An application example of the energy-saving kiln and the energy-saving method for the kiln according to Embodiment 1 of the present invention in a gas furnace.

[0057] Figure 4 Schematically provides a partial structural diagram of the energy-saving kiln 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 the blackbody element 11 . ...

Abstract

The invention provides an energy-saving kiln which comprises linings made of refractory fibers, accommodating rooms and black body elements. The accommodating rooms are arranged on the linings made of the refractory fibers; the black body elements are hollow, an opening is arranged at one end, which points to the center of a hearth, of each black body element, and one end of each black body element is embedded in the corresponding accommodating room; and the linings made of the refractory fibers are at least partially arranged on the wall of the kiln. The energy-saving kiln has the advantages of reliability in installation, good energy-saving effect, low cost, high efficiency in construction, and the like.

Description

technical field [0001] The invention relates to a furnace, in particular to an energy-saving furnace and an energy-saving method. Background technique [0002] The heat transfer theory and a large number of engineering cases prove that the black body technology can increase the emissivity of the furnace and strengthen the radiation heat transfer of the furnace wall, which is an efficient furnace energy-saving technology. Refractory fiber furnace lining can effectively reduce the heat dissipation and heat storage loss of the furnace wall, and is increasingly used as the lining of modern furnaces. [0003] At present, blackbody elements can only be installed on refractory brick masonry or refractory castable furnace walls. In a kiln lined with refractory fiber, the installation of black body elements encountered huge technical obstacles: [0004] General adhesives can only be bonded to very light flake-like fibers, and the adhered objects with a little weight will peel off f...
