[0041] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0042] The present embodiment provides a heat preservation structure 10, which is applied to the heat preservation of heat storage equipment and can meet the heat preservation requirements of existing high-temperature heat storage boxes and the requirements for regular replacement of electronic components.

[0043] See also Figure 1 , Figure 1 The specific structure of the thermal insulation structure 10 in this embodiment is shown.

[0044] The heat preservation structure 10 includes a heat preservation cover bottom layer 11 and a heat preservation cover body 12. The heat preservation cover bottom layer 11 is formed with a slot, and the slot is used to be detachably connected to the heat insulation block 32 of the equipment bottom plate 30 provided on the heat storage device 10a. The bottom end of the heat preservation cover body 12 is detachably connected to the heat preservation cover bottom layer 11. The heat preservation cover bottom layer 11 and the heat preservation cover body 12 together constitute a heat preservation space for accommodating the heat storage device. The heat storage device 10a is shown in the figure.

[0045] The thermal insulation structure 10 includes a thermal insulation cover bottom layer 11 and a thermal insulation cover body 12. The thermal insulation cover bottom layer 11 and the thermal insulation cover body 12 have the effect of thermal insulation and heat insulation, which can avoid the heat energy loss of the heat storage device, and can also make the heat storage device installed with the thermal insulation structure 10, the outer surface of the overall structure is at 40℃~50℃ (generally, the surface temperature of the heat storage device is 80~800℃), so as to reach a safe temperature that the human body can withstand. The thermal insulation cover bottom layer 11 is used to be arranged on the bottom surface of the heat storage device, and is detachably connected to the insulation block, so as to facilitate the separation of the thermal insulation cover bottom layer 11 and the device bottom plate. The thermal insulation cover body 12 is used to be arranged on the outer surface of the heat storage device, and is detachably connected to the thermal insulation cover bottom layer 11, so as to wrap each surface of the heat storage device together with the thermal insulation cover bottom layer 11 to keep it warm. Since the thermal insulation cover bottom layer 11 and the thermal insulation cover body 12 are detachably matched, they can be easily disassembled to meet the needs of regular replacement of electronic components.

[0046] The bottom layer 11 of the heat-insulating cover and the main body 12 of the heat-insulating cover are both double-layer flexible heat-insulating protective covers.

[0047] The double-layer flexible heat-insulating protective cover comprises an inner heat-insulating cover 13 and an outer heat-insulating cover 14, which are arranged from the inside to the outside. It should be noted that the direction from the inside to the outside can be understood as the direction in which the outer surface of the heat storage device extends outward with the heat storage device as a reference point.

[0048] See also Figure 2 , Figure 3 as well as Figure 4 , Figure 2 The specific structure of the double-layer flexible heat insulation protective cover is shown. Figure 3 The specific structure of the inner thermal insulation sleeve 13 is shown. Figure 4 The specific structure of the outer thermal insulation sleeve 14 is shown.

[0049] The inner layer insulation sleeve 13 comprises an inner layer protective material and an inner layer insulation material, and the inner layer insulation material is located between the two inner layer protective materials.

[0050] In this embodiment, the inner protective material is a high-silica cloth 20, and the inner thermal insulation material is a ceramic fiber blanket. The ceramic fiber blanket is located between two high-silica cloths 20, wherein two layers of 30 mm thick ceramic fiber blankets 21 and one layer of 20 mm thick ceramic fiber blanket 22 are sequentially arranged between the two high-silica cloths 20 from the inside to the outside.

[0051] The outer layer thermal insulation sleeve 14 comprises an outer layer protective material, an outer layer thermal insulation material and a thermal insulation material; the outer layer thermal insulation material is located between two outer layer protective materials, and the thermal insulation material is connected to the outer layer protective material located on the outside.

[0052] The outer protective material includes high-silica cloth 20, the outer thermal insulation material includes interconnected ceramic fiber blankets and aerogel felts, and the thermal insulation material is a long-distance low-energy heat network high-temperature resistant convection layer 24. Among them, two layers of 20mm thick ceramic fiber blankets 22 and three layers of 10mm thick aerogel felts 23 are interconnected, and the ceramic fiber blankets and aerogel felts are located between the two high-silica cloths 20, and the long-distance low-energy heat network high-temperature resistant convection layer 24 is connected to the high-silica cloth 20 located on the outside.

[0053] Among them, in a possible implementation, as Figure 1 As shown, the insulation cover body 12 includes an insulation cover side enclosure 120 for being arranged on the side wall of the heat storage device and an insulation cover top layer 121 arranged on the top surface of the heat storage device, the bottom end of the insulation cover side enclosure 120 is detachably connected to the insulation cover bottom layer 11, and the top end of the insulation cover side enclosure 120 is detachably connected to the insulation cover top layer 121.

[0054] It should be noted that the insulation sleeve side 120 and the insulation sleeve top layer and insulation sleeve bottom layer 11 can be detachably connected in an overlapping manner.

[0055] It should be noted that for the high-temperature heat storage box used to store heat, the temperature itself is high and the heat loss is serious. The surface of the equipment contains many flanges, protruding water inlet and outlet pipes at both ends, plate exchangers, and electronic components that need to be replaced regularly (such as heating rods, temperature probes, etc.). Traditional insulation methods cannot meet this demand. The actual operating temperature of the box is 500℃ and the design temperature is 600℃. In order to reduce heat loss and improve energy utilization, a detachable insulation method is required on the surface. After insulation, the outer surface temperature is required to be around 40℃~50℃.

[0056] To this end, a heat preservation method is also provided below, comprising the following steps:

[0057] Providing the thermal insulation structure 10 and the heat storage device described above;

[0058] The surface of the heat storage device is leveled, wherein this step includes inserting high temperature resistant soft insulation material, such as ceramic fiber blanket, into the channel steel on the surface of the heat storage device. The side protruding parts of the heat storage device are covered with two layers of high temperature resistant soft insulation material in the horizontal and vertical directions, and wrapped with insulation material. For example, the output part of the copper pipes on both sides of the heat storage device is covered with two layers of ceramic fiber blanket strips in the horizontal and vertical directions, and wrapped with a high temperature resistant long-distance transmission low energy consumption high temperature reflective layer.

[0059] Place the insulation block on the bottom plate of the heat storage device and insert it into the slot of the bottom layer of the insulation cover. Figure 5 As shown in the figure, the bottom plate of the equipment has an angle steel groove for fixing the insulation block. The insulation block is half inserted into the angle steel groove and half inserted into the preset slot on the bottom layer of the insulation cover. Figure 5 The equipment base plate 30 and the angle steel channel 31 are shown in FIG.

[0060] The insulation sleeve body is installed on the heat storage equipment, wherein the insulation sleeve body includes an inner insulation sleeve and an outer insulation sleeve. The steps of installing the insulation sleeve body on the heat storage equipment include: installing the inner insulation sleeve and installing the outer insulation sleeve and insulating the exposed copper pipe. The steps of installing the inner insulation sleeve include: the inner insulation sleeve is sequentially provided with high-silica cloth, two layers of 30mm thick ceramic fiber blanket, one layer of 20mm thick ceramic fiber blanket and high-silica cloth from the inside to the outside, pre-opening holes at the outlet holes and bolt positions of the heat storage equipment, the openings are completely sutured and not exposed, and wrapped with a high-temperature resistant long-distance low-energy consumption high-temperature reflective layer. The steps of installing the outer insulation sleeve include: the outer insulation sleeve is sequentially provided with high-silica cloth, two layers of 20mm ceramic fiber blanket, three layers of 10mm thick aerogel felt, high-silica cloth and a high-temperature resistant convection layer of a long-distance low-energy consumption heat network from the inside to the outside. Among them, the aerogel felt can be lightly scratched with a knife for easy bending, the inner and outer layers of the wire outlet opening should be staggered, and a wiring harness channel is reserved for the wiring harness.

[0061] The steps of heat preservation treatment for the external parts of the heat storage equipment include the following:

[0062] Performing insulation treatment on the components of the heat storage device extending out of the device box. The steps of performing insulation treatment on the components of the heat storage device extending out of the device box include:

[0063] High-temperature resistant soft insulation materials are used at the parts outside the box, and holes are opened at the corresponding parts. The high-temperature resistant soft insulation materials are inserted into the parts, and the sides of the high-temperature resistant soft insulation materials are stuffed into the lower pressure seam of the insulation sleeve body. For example, two ceramic fiber blankets are used at the copper tubes on both sides of the heat storage equipment, and holes are opened at the copper tubes. The ceramic fiber blankets are integrally inserted into the copper tubes, and the sides of the ceramic fiber blankets are stuffed into the lower pressure seam of the insulation sleeve body (wherein, various insulation materials are connected by pressure seams in the inner insulation sleeve and the outer insulation sleeve), and then aerogel felt strips wrapped with high-silica cloth are inserted horizontally and vertically crosswise, and the inner layer of the pores of the heat storage equipment is stuffed with aluminum silicate wool, and the outer layer is stuffed with aerogel felt to seal the pores, which are fixed by stainless steel belts or iron wires.

[0064] The exposed parts are insulated, and the steps include: wrapping the exposed parts of the heat storage device with high-temperature resistant soft insulation material, and spirally wrapping tape on the surface. For example, wrapping the exposed copper tube of the heat storage device with an aluminum silicate ceramic fiber blanket, and spirally wrapping aluminum foil tape on the surface.

[0065] The exposed metal components of the heat storage device are subjected to insulation treatment, and the steps are as follows: inserting a high temperature resistant soft insulation material into the exposed metal components, for example, inserting a ceramic fiber blanket insulation sleeve into the exposed metal components.

[0066] It should be noted that the insulation method described above can be adapted to energy storage boxes of various sizes.

[0067] It should be noted that the thickness of the inner insulation sleeve and the outer insulation sleeve described above can be calculated according to the existing formula. Since it is the existing technology, it will not be described in detail in this embodiment.

[0068] It should be noted that the inner insulation cover and each layer of insulation material in the outer insulation cover, as well as the inner insulation cover and the outer insulation cover are all staggered with upper and lower pressed seams to solve the heat leakage problem caused by the direct air access of the seams. At the same time, it also ensures that the cable holes of the heating elements, temperature probes, etc. will not be directly exposed to the air, thereby ensuring the insulation effect.

[0069] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
