The composite heat insulation unit comprises aerogel insulation cotton 2 arranged on the inner side and aluminum silicate insulation cotton 3 arranged outside the aerogel insulation cotton 2. The utility model uses the aerogel insulation cotton 2 with relatively good heat preservation effect and the aluminum silicate insulation cotton 3 with relatively poor heat preservation effect to form the composite heat insulation unit, so as to improve the heat preservation effect of the high temperature pipeline 1 at a low cost. Specifically, the aerogel insulation cotton 2 with relatively good heat preservation effect is tightly attached to the outer circumferential surface of the high temperature pipeline 1, the aluminum silicate insulation cotton 3 with relatively poor heat preservation effect is wrapped outside the aerogel insulation cotton 2, and the holding unit is used in cooperation with the above structure to improve the heat preservation effect.

[0026] Further, the drawings will be described below in conjunction with the embodiments of the utility model. Figure 1 , 2, 4, the inner side of the aluminum silicate insulation cotton 3 is provided with a groove, and the aerogel insulation cotton 2 is arranged in the groove. Since the composite heat insulation unit is a double-layer structure, and the high-temperature pipeline 1 will expand and displace during the process of passing the high-temperature fluid, the displacement between the aerogel insulation cotton 2 and the aluminum silicate insulation cotton 3 will be caused, thereby affecting the heat preservation effect; based on this, preferably, the utility model discloses that the groove is arranged on the aluminum silicate insulation cotton 3, and the aerogel insulation cotton 2 is arranged in the groove, so that the purpose of limiting the aerogel insulation cotton 2 is realized; the above structure can solve the problem that the aerogel insulation cotton 2 and the aluminum silicate insulation cotton 3 are always wrapped around the high-temperature pipeline 1 when the high-temperature pipeline 1 expands and displaces, thereby achieving the purpose of solving the above technical problem.

[0027] Further, referring to Figure 1 , 3 , 5 and 6, the holding unit comprises a lower pipe support 4 and an upper pipe clamp 5; the two sides of the lower pipe support 4 are provided with lower pipe support fastening parts 6, the lower pipe support fastening parts 6 are provided with bolt through holes, the two sides of the upper pipe clamp 5 are provided with upper pipe clamp fastening parts 7, the upper pipe clamp fastening parts 7 are provided with bolt through holes, and the two bolt through holes are connected by high-strength bolts 13. By cooperating the high-strength bolts 13 with the lower pipe support 4 and the upper pipe clamp 5, the composite heat insulation unit can be closely attached to the high-temperature pipeline 1, so that the heat preservation effect is improved.

[0028] Further, referring to Figure 1 , 5 and 6, the length of the lower pipe support 4 is greater than the length of the upper pipe clamp 5, the lower pipe support fastening parts 6 are provided with a plurality of bolt through holes, and the upper pipe clamp fastening parts 7 are provided with one bolt through hole; the upper pipe clamp 5 is provided with two upper pipe clamps arranged at positions corresponding to the edges of the groove. In the utility model, the lower pipe support fastening parts 6 are provided with a plurality of bolt through holes, and the upper pipe clamp fastening parts 7 are provided with one bolt through hole, so that the installation position of the upper pipe clamp 5 can be adjusted according to the actual situation. Meanwhile, the cooperation between the lower pipe support 4 and the upper pipe clamp 5 can not only make the composite heat insulation unit closely attached to the high-temperature pipeline 1, but also tightly fix the edge position of the groove, so that the aerogel insulation cotton 2 can be fixed in a targeted manner, thereby achieving the purpose of firmly limiting the aerogel insulation cotton 2.

[0029] Further, referring to Figures 1-3 , the sliding part comprises an upper sliding pair 8 and a lower sliding pair 9, the upper sliding pair 8 is connected to the bottom of the lower pipe support 4 through a pipe support bracket 10, and the bottom of the lower sliding pair 9 is connected to the top of a pipe support beam 11. By arranging the sliding part, the displacement of the high-temperature pipeline 1 caused by the high-temperature fluid can be compensated, and the holding unit can realize the purpose of heat preservation of the high-temperature pipeline 1 through the composite heat insulation unit at the same time of compensation.

[0030] Further, referring to Figure 1 The utility model discloses a scale 12 is equipped on the lower pipe support 4 for marking the recess edge position and recording the high temperature pipeline relative displacement.

Further, the scale 12 can be set as 0 in the middle, negative number on the left side and positive number on the right side. The form can facilitate data reading and observing the displacement direction and value of the lower pipe support 4. The displacement direction and value can be compared with the design value, so that whether the pipeline is normally operated can be conveniently judged. For example, when the displacement value of the lower pipe support 4 is too small, it can be judged that no fluid passes through the high temperature pipeline 1, and the high temperature pipeline 1 may be blocked.

[0031] The utility model discloses a specific working process as follows: in actual use process, the lower pipe support 4, pipe support bracket 10 and upper sliding pair 8 can be an integral structure, and the lower sliding pair 9 and pipe support crossbeam 11 can be an integral structure. The main structure of the utility model is combined by matching the upper sliding pair 8 and the lower sliding pair 9. On this basis, the aerogel heat insulation cotton 2 is placed in the recess on the inner side of the aluminum silicate heat insulation cotton 3, and the composite heat insulation unit composed of the aerogel heat insulation cotton 2 and the aluminum silicate heat insulation cotton 3 is wrapped outside the high temperature pipeline 1. Meanwhile, the position of the recess edge is recorded by the scale 12. Finally, the lower pipe support 4 and the upper pipe clamp 5 are tightly fixed by the high-strength bolt 13, and the two upper pipe clamps are ensured to be on the edge positions on both sides of the recess. After the above structure is fixed, the relative position of the scale 12 and the lower sliding pair 9 is observed and recorded. After the high temperature fluid is input, the relative position of the scale 12 and the lower sliding pair 9 is observed again. The displacement direction and value are determined to realize the characteristics of detecting the operating condition of the high temperature pipeline 1. The utility model has the characteristics of simple structure, reasonable design, low investment cost and good heat preservation effect. Meanwhile, the utility model can conveniently detect whether the high temperature pipeline 1 is normally operated.
