Problems solved by technology

The installation and support of the insulation layer need to be realized through the channel steel fixed on the cement wall of the pile pit, but there must be gaps at the connection between the channel steel and the insulation layer, which will lead to heat leakage, and eventually lead to the surface of the channel steel and local piles. The temperature of the cement wall of the pit is too high, which reduces the durability of the material

Embodiment Construction

[0013] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0014] A channel steel bracket with a baffle structure for fixing the thermal insulation layer outside the reactor;

[0015] As stated in the background technology, the pores existing between the existing insulation layer and the channel steel support are as follows: figure 1 As shown, one end of the channel steel bracket is fixed to the cement wall of the pile pit, and the other end is inserted into the hole of the insulation layer structure to support the insulation layer. For the convenience of installation, the aperture of the insulation layer is always slightly larger than the channel steel section structure. The groove in the middle of the channel steel bracket together forms the pore structure at the connection between the insulation layer and the channel steel.

[0016] The installation and support...

Abstract

The invention belongs to the technical field of reactor engineering, and relates to channel steel supports with a flow blocking sheet structure for fixing a heat preservation layer outside a reactor.The channel steel supports are distributed on the outer side of a pit, one ends of the channel steel supports are fixed with the cement wall surface of the pit, the other ends of the channel steel supports are inserted into holes in the heat preservation layer and are used for supporting the heat preservation layer; the pore diameter of the holes in the heat preservation layer is larger than thatof the steel channel supports, and holes are formed between each channel steel support and the holes in the heat preservation layer; and flow blocking sheets are arranged in the length direction of the channel steel supports located on the upper portion of the heat preservation layer, the flow blocking sheets are located between the heat preservation layer and the wall surface of the pile pit, andthe cross sections of the flow blocking sheets are larger than the cross section of the heat preservation layer, so that the flow resistance is ensured. According to the novel channel steel structurewith the flow blocking sheet structure, the heat of the pore leakage and the cold air from the outer side of the heat preservation can be effectively mixed, and the influence of too high local temperature caused by directly washing the wall surface of the pit by heat is reduced.

Description

technical field [0001] The invention belongs to the technical field of reactor engineering, and relates to a channel steel bracket with a spoiler structure for fixing the thermal insulation layer outside the reactor. technical background [0002] Because nuclear power generation technology is more economical and environmentally friendly than traditional power generation technologies, and its power generation efficiency is more objective, it has been widely respected by countries all over the world. Over the past few decades, nuclear power technology has developed rapidly. The metal insulation layer on the outside of the reactor pressure vessel is used to reduce heat loss as much as possible, and at the same time reduce the fatigue loss of the reactor pit structure caused by thermal stress. The installation and support of the insulation layer need to be realized through the channel steel fixed on the cement wall of the pile pit, but there must be gaps at the connection betwe...
