Embodiment 1）

[0051] See figure 1 with figure 2 , The thermal insulation device of the glass tank kiln of this embodiment is the thermal insulation device of the float glass tank kiln, including the thermal insulation composite layer 2 and the fixing member 5 . The thermal insulation composite layer 2 is composed of an aluminum silicate fiber blanket layer 21 and a first airgel thermal insulation blanket layer 22 .

[0052] The aluminum silicate fiber blanket layer 21 and the first airgel thermal insulation blanket layer 22 are sequentially laid and covered on the outer surfaces of all parts of the glass tank kiln where the thermal insulation layer 1 is provided in the order from the inside to the outside, and the fixing member 5 is arranged on the first Outside the airgel thermal insulation blanket layer 22, the thermal insulation composite layer 2 is compacted and compacted on the outer surface of the thermal insulation layer 1 of the glass tank kiln. The thermal insulation layer 1 is ...

Embodiment 2）

[0061] See image 3 , The rest of this embodiment is the same as that of Embodiment 1, except that: the heat preservation device of the glass tank kiln of this embodiment also includes a reflective layer 4 . The reflective layer 4 is an aluminum plate or galvanized iron sheet with a thickness of 0.5 mm, covering the outer surface of the first airgel insulation blanket layer 22 of the thermal insulation composite layer 2, and the fixing part 5 is arranged outside the reflective layer 4, so that the reflective layer 4 and The thermal insulation composite layer 2 is pressed sequentially from the outside to the inside, and is compacted on the outer surface of the thermal insulation layer 1 of the glass tank kiln.

[0062] Compared with the heat preservation device of embodiment 1, the heat preservation device of this embodiment can reflect a part of the heat radiated from the heat preservation layer 1 of the glass tank kiln back to the heat preservation layer 1 due to the existenc...

Embodiment 3）

[0064] See Figure 4 with Figure 5 , the rest of this embodiment is the same as that of Embodiment 1, except that: the thermal insulation device of this embodiment also includes a thermal insulation composite layer 3 . The thermal insulation composite layer 3 is divided into a single thermal insulation composite layer 3a and a double thermal insulation composite layer 3b according to the number of glass fiber felt layers and airgel thermal insulation blanket layers included. The single thermal insulation composite layer 3a has only one composite layer, that is, the first glass fiber felt layer 31 and the second airgel thermal insulation blanket layer 32 are arranged sequentially from inside to outside. The double thermal insulation composite layer 3b has 2 composite layers, that is, the first glass fiber blanket layer 31, the second airgel thermal insulation blanket layer 32, the second glass fiber blanket layer 33 and the third airgel thermal insulation blanket layer 34 acc...

Abstract

The invention discloses an insulation apparatus for a glass tank furnace. The insulation apparatus comprises, from interior to exterior, a heat insulation composite layer, an insulation composite layer, a reflecting layer and a fixing part, wherein the heat insulation composite layer is mainly composed of an alumina silicate fiber blanket layer and a first aerogel insulation blanket layer, the alumina silicate fiber blanket layer and the first aerogel insulation blanket layer are successively, from interior to exterior, laid and covered on the external side surfaces of all the positions of the glass tank furnace provided with an insulation layer, the insulation composite layer is composed of a glass fibrofelt layer or rock wool layer and an aerogel insulation blanket layer, the reflecting layer is an aluminum plate or galvanized sheet iron, and the fixing part is arranged out of the reflecting layer to allow the heat insulation composite layer, the insulation composite layer and the reflecting layer to be tightly compacted on the external surface of the insulation layer of the glass tank furnace. The insulation apparatus for the glass tank furnace in the invention is applied at the outer side of the insulation layer of a traditional float glass tank furnace, enables heat dissipation quantity of the insulation layer of the traditional glass tank furnace to be greatly reduced and has a substantial secondary insulation effect on the glass tank furnace.

Description

technical field [0001] The invention relates to a heat preservation device for a glass tank kiln, in particular to a heat preservation device for a float glass tank kiln. Background technique [0002] Glass refers herein to inorganic glass whose main component is silica. The glass industry is closely related to building energy conservation and is a typical resource and energy-consuming industry. The annual energy consumption of flat glass in my country is about 1 million tons of standard coal, and fuel consumption accounts for more than 80% of the energy consumption of glass enterprises; the average unit consumption is 7800 kJ / kg glass liquid (1866 kcal / kg glass liquid), which is higher than the international average level 20%, more than 30% higher than the international advanced level. [0003] Due to the continuous rise of energy prices in recent years, fuel costs have seriously affected the economic benefits of glass companies. The increasing energy costs require glass f...
