Steam heat accumulator and method for fixing thermal insulating layer thereof

Abstract

An embodiment of the invention discloses a steam heat accumulator comprising a tank body, wherein a thermal insulating layer is arranged on the tank body; a plurality of hoops, end rings, longitudinal braces and radial braces are further arranged between the thermal insulating layer and the tank body; the end rings are arranged at the end portions of the tank body; the hoops are arranged on the tank body; the longitudinal braces are arranged between adjacent hoops; each radial brace is arranged between one end ring and the hoop adjacent to the end ring; and the thermal insulating layer is fixed to the longitudinal braces and the radial braces. In the embodiment of the invention, the thermal insulating layer can be smoothly fixed to the steam heat accumulator by means of the hoops arrangedon the tank body of the steam heat accumulator; and the thermal insulating layer is not needed to be welded on the outer surface of the steam heat accumulator by way of fixing using the hoops; therefore, the thermal insulation performance of the steam heat accumulator in the embodiment of the invention can be ensured.

Description

technical field [0001] The invention relates to the technical field of steelmaking steam recovery, in particular to a fixing method for a steam heat accumulator and its insulation layer. Background technique [0002] A heat accumulator is a device that stores excess heat in the steam supply system of an industrial boiler and releases the stored heat when needed. There are two types of regenerators: variable pressure and constant pressure. The working pressure of the variable pressure regenerator changes with the increase or decrease of the stored heat, and the most typical one is the steam regenerator. [0003] Such as figure 1 As shown, the steam accumulator 12 is arranged between the boiler 11 and the steam end 15, the valve 13 is arranged between the inlet pipe of the steam accumulator 12 and the boiler 11, the outlet pipe of the steam accumulator 12 is connected to the steam end 15 A valve 14 is provided in between. When the evaporation of steam in the boiler 11 is gr...

AI Technical Summary

Problems solved by technology

However, due to the large volume of the steam accumulator (diameter 3m×length 16m), and it has passed the pressure inspection before leaving the factory. When it is transported to the construction site for thermal insulation, it is not allowed to weld on its surface with hot fire

The thermal insulation layer on the outer surface of the steam accumulator is not well fixed, so the thermal insulation performance of the steam accumulator cannot be guaranteed
