AI Technical Summary

Technical Problem

The refractory bricks in the existing recycled lead smelting furnaces are prone to burning and burning, which will last a long time to replace, which will affect production.

Method used

A furnace wall cooling wall is designed, including the cooling wall body of arc-shaped rectangular blocks, a serpentine tube cooling system, a water inlet and water outlet, and a brick-inlay structure of refractory bricks. The heat is quickly derived through the serpentine tube water cooling system, forming a slag protective layer and extending its service life.

Benefits of technology

The serpentine tube cooling system effectively reduces the furnace wall temperature, extends the service life of the refractory bricks, shortens the replacement time, improves the cooling capacity and slag hanging performance of the furnace wall, and ensures the stability and safety of production.

Abstract

A furnace wall cooling stave of a secondary lead smelting furnace belongs to the technical field of secondary lead smelting. The furnace wall cooling stave includes: a furnace wall cooling stave body, a furnace wall combustion-supporting hole, a furnace wall fixing bolt, a furnace wall brick dovetail groove, a furnace wall cooling stave serpentine pipe, a furnace wall water inlet, a furnace wall water outlet and a furnace wall refractory brick; there are furnace wall combustion-supporting holes and fixing holes on the furnace wall cooling stave body, and the furnace wall fixing bolts fix the furnace wall cooling stave body to the furnace shell through the fixing holes; there are two furnace wall cooling stave serpentine pipes, which are embedded in the furnace wall cooling stave body side by side, and there are furnace wall water inlet and furnace wall water outlet at both ends of the furnace wall cooling stave serpentine pipe respectively leading to the outside of the furnace wall cooling stave; there is a furnace wall brick dovetail groove on the back of the furnace wall cooling stave body; the combustion-supporting hole is a furnace wall combustion-supporting hole including: a furnace wall spray gun hole and a furnace wall burner hole. Advantages: simple structure, low cost and high strength. It is convenient to replace the furnace wall refractory bricks, which greatly shortens the replacement time.
