Problems solved by technology

[0003] Due to the stave's approximate rectangular parallelepiped structure, the existing stave water exchange pipes are mostly arranged in parallel or in a serpentine shape, and the inner wall of the heat exchange pipe is a smooth arc surface. No matter what the arrangement is, there will be local overheating

Embodiment Construction

[0019] In order to clearly illustrate the technical features of the solution, the solution will be described below through specific implementation modes.

[0020] Such as figure 1 A high-efficiency heat exchange cooling stave for a blast furnace is shown, including a cooling stave body 2 and a water exchange pipe 1. The middle section of the water exchange pipe is arranged in the stave body, and the two ends of the heat exchange pipe are respectively provided with The bending section is formed by bending to facilitate the layout of the blast furnace cooling water pipe.

[0021] In this embodiment, according to the situation that one side of the blast furnace cooling wall is heated, 6 to 10 spiral bosses 3 are arranged on the inner wall of the heat exchange pipe, and spiral grooves 4 are formed between adjacent spiral bosses. The axis of the spiral boss It coincides with the axis of the heat exchange pipe, so that the cooling water entering the heat exchange pipe flows along t...

Abstract

The invention relates to an efficient heat exchange cooling wall for a blast furnace and a cooling method of the efficient heat exchange cooling wall. The efficient heat exchange cooling wall for theblast furnace comprises a cooling wall body and a heat exchange water pipe, multiple spiral bosses are arranged on the inner wall of the heat exchange water pipe, and a spiral groove is formed betweenevery two adjacent spiral bosses. The spiral bosses are arranged on the inner wall of the heat exchange water pipe to form the spiral grooves, and therefore cooling water flows in the axial directionand flows in the circumferential direction of the heat exchange water pipe at the same time, the heat exchange water pipe is heated evenly, then the portions, on the two sides of the heat exchange water pipe, of the cooling wall are heated evenly, and the problem of local overheating caused by single-side heating of the cooling walls is solved.

Description

technical field [0001] The invention relates to the technical field of blast furnace staves, in particular to a blast furnace high-efficiency heat exchange stave and a cooling method thereof. Background technique [0002] The stave is the cooling equipment of the blast furnace body, its main function is to protect the furnace shell, cool and support the refractory material and maintain a reasonable furnace shape. The stave is installed on the inner surface of the blast furnace shell, and the heat exchange pipe passes through the furnace shell. Its main working principle is to use the circulating cooling water in the heat exchange pipe to discharge heat out of the furnace. [0003] Due to the stave's approximate rectangular parallelepiped structure, the existing stave water exchange pipes are mostly arranged in parallel or in a serpentine shape, and the inner wall of the heat exchange pipe is a smooth arc surface. No matter what the arrangement is, there will be local overhe...
