AI Technical Summary
Technical Problem
The thermal compensation of the riser and descending pipes in the heat absorption tower has problems such as large space occupation, high project investment, frequent support hangers failures, and maintenance problems.
Method used
The molten salt pipeline system adopts a folded bent structure, and supports and fixes the pipeline by combining support steel beams and various forms of support hangers (such as spring hangers and limit hangers), reducing the length of pipes and improving system stability.
Benefits of technology
It reduces the project cost, increases the yield of photothermal power stations, reduces the project volume of factory piping and construction site piping, and improves the convenience and efficiency of maintenance and operation.

Abstract
The invention belongs to the field of heat absorption towers, and provides a molten salt pipeline system in a heat absorption tower and the heat absorption tower. Wherein the molten salt pipeline system in the heat absorption tower comprises a molten salt pipeline, a support hanger and a combined support steel beam; the combined supporting steel beam comprises a main beam and a supporting beam; the molten salt pipeline comprises an upper tower cold molten salt pipeline and a lower tower hot molten salt pipeline; the upper tower cold molten salt pipeline and the lower tower hot molten salt pipeline are respectively formed by connecting a plurality of pi-shaped bends end to end; the pi-shaped bend is formed by connecting two bent bends end to end; the bent bend is composed of a first vertical pipe, a first elbow, an inclined pipe, a second elbow and a second vertical pipe which are connected in sequence; the angle of the first elbow and the angle of the second elbow are both smaller than or equal to 75 degrees. The upper tower cold molten salt pipeline and / or the lower tower hot molten salt pipeline are rooted on the corresponding combined supporting steel beams through the supporting hangers; and the upper tower cold molten salt pipeline and the lower tower hot molten salt pipeline are arranged between the main beam and the cylinder wall of the heat absorption tower.
