A method for optimal configuration of cooling water pipes and a water pipe structure with uniform distribution

Abstract

The invention belongs to the field of blast furnace cooling systems, and specifically relates to an optimal configuration method of a cooling water pipe and a uniform distributing type water pipe structure. The uniform distributing type water pipe structure comprises a first big ring of which the connecting inner diameter relative to a main water inlet / a main water outlet is the same as the mainwater inlet / the main water outlet, a transverse distributing pipe, a vertical distributing pipe, a second big ring which is connected to the vertical distributing pipe and the transverse distributingpipe, and a third big ring which is connected to the vertical distributing pipe and a cooling wall water pipe, wherein the first big ring, the transverse distributing pipe, the second big ring, the vertical distributing pipe and the third big ring sequentially communicate with each other; the vertical distributing pipe and the second big ring are not on the same horizontal plane; and the third big ring communicates with the cooling wall water pipe. With the adoption of the uniform distributing type water pipe structure, water on the cooling wall of a blast furnace body in the circumferentialdirection is uniformly distributed, and moreover, the damage of the cooling wall is reduced, so that the service life of the blast furnace is prolonged.

Description

technical field [0001] The invention belongs to the field of blast furnace cooling systems, and in particular relates to a method for optimizing configuration of cooling water pipes and a water pipe structure for uniform flow distribution. Background technique [0002] Blast furnace longevity has become an important symbol and part of the progress of contemporary ironmaking technology. Especially in the blast furnace, the heat load is high, the heat flow impact is large, and it is highly destructive to the furnace cooling equipment. Therefore, improving the life of the furnace cooling equipment is one of the key factors to ensure the longevity of the blast furnace; In addition to the anti-corrosion ability of carbon bricks and enhancing the heat transfer capacity of the cooler, improving the uniformity of the water supply method is also an important method. By improving the uniformity of the water supply method, the damage of the blast furnace cooler can be effectively reduc...

AI Technical Summary

Problems solved by technology

This water supply method can greatly improve the water distribution uniformity of the cooling system, but the water distribution uniformity of the intermediate cooling wall is largely affected by the water distribution uniformity of the outer large ring pipe, due to the water distribution of the outer large ring pipe It is not uniform, so the water distribution of the internal cooling wall is still not uniform
