[0023] Embodiment 1

[0024] This utility model provides a heat-insulating and heat-resistant box-type energy-saving device, including a preheating layer 1, a heat insulation layer 2 and an outer box 3. The heat insulation layer 2 and the preheating layer 1 are arranged sequentially inside the outer box 3. The preheating layer 1 includes an inner top cover 11, an inner bottom plate 12, an inner shell a13 and an inner shell b14.

[0025] In this embodiment, various system connection pipe interfaces and components can be installed on the outer casing 3.

[0026] In this embodiment, the insulation layer 2 is composed of high temperature-resistant heat insulation material, and the insulation layer 2 is disposed on the outer surface of the preheating layer 1.

[0027] In this embodiment, the inner base plate 12, the inner shell a13, and the inner shell b14 constitute the main body of the preheating layer 1. The inner shell a13 and the inner shell b14 are welded to the inner base plate 12. There is also a gap between the inner shell a13 and the inner shell b14 so that the preheating layer 1 forms a double-layer structure.

[0028] In this embodiment, the inner top cover 11 is installed above the main body of the preheating layer 1. The inner top cover is connected to the inner shell a13 and the inner shell b14. The inner bottom plate 12, the inner shell a13, the inner shell b14, and the inner top cover 11 constitute a high-temperature sealed space.

[0029] In this embodiment, a connecting pipe 15 is installed on the inner top cover 11 via a flange 16, and the connecting pipe 15 connects the inside of the preheating layer 1 to the outside.

[0030] In this embodiment, the preheating layer 1 is provided with a partition 17 and a flow equalization plate 18.

[0031] This utility model is a box-type thermal insulation device. During normal operation, the space inside the preheating layer 1 is isolated, which is the high-temperature working environment. In this working state, it is necessary to continuously maintain this environment at a stable high temperature, and to minimize the temperature of the outer surface of the outer casing 3 to reduce internal energy loss.

[0032] like Figures 1-2 As shown, during normal system operation, the system medium (such as gas or liquid) first passes through inlet 4 ( Figure 1 The medium enters the inlet of preheating layer 1, and then is distributed by the flow equalization plate 18 to ensure uniform flow of the system medium in preheating layer 1. At this time, the internal heat (high temperature) exchanges heat with the system medium (low temperature) in preheating layer 1 through the inner shell b14. This heat exchange continues throughout the entire transfer process in preheating layer 1. Then, the system medium passes through outlet 5 and connecting pipe 15 (…). Figure 1) into the internal environment. The preheating layer 1 of the utility model, using the heat that system can lose, preheats the medium that needs to be warmed, rationally uses the heat of system itself, reduces the energy loss in system to a great extent, and reduces the energy loss of system to outside, reduces the surface temperature, and improves the safety.

[0033] In combination with the utility model, after the heat in the system preheats the continuously-inlet medium in the above heat exchange process, the residual heat continues to dissipate outward through the heat preservation layer 2, at this time, the heat reaching the outer box body 3 is extremely low after passing through the high-temperature-resistant heat insulation material of the heat preservation layer 2, basically satisfying the surface temperature safety factor.

[0034] The structure, function and connection form disclosed in the present application can be realized by other ways. For example, the above-described embodiments are only illustrative, for example, a plurality of components can be combined or integrated into another component; in addition, each functional component in each embodiment herein can be integrated into one functional component, or each functional component can exist physically alone, or two or more functional components can be integrated into one functional component.

[0035] The above is only the preferred embodiment of the utility model, and it should be pointed out that, for ordinary skilled person in the art, without departing from the creative concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model.
