Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nozzles, in particular to a high-temperature resistant nozzle for a vertical kiln spray cooling water gun. Background Art
[0002] A vertical kiln is a thermal equipment that continuously calcines clinker with top loading and bottom discharge. It consists of a kiln body, loading and discharge devices, and ventilation equipment. It is widely used to calcine various refractory materials and lime. Its advantages include low capital investment, small footprint, high clinker efficiency, low fuel consumption, and ease of mechanization and automation.
[0003] Hot vertical kilns have a long history of application in the refractory industry. The ancient naturally ventilated vertical kiln is shaped like a bottle, commonly known as a bottle kiln, and is the predecessor of the modern vertical kiln. In the 1960s, the structure and operation of the vertical kiln were significantly improved. The dolomite magnesia vertical kiln calcined with a vaporized cooling wall instead of a refractory brick lining to solve the problem of sticking to the kiln. The material sealing device is used, and the discharge can continue without stopping the wind, creating conditions for the automation of the entire kiln system operation. The utilization coefficient has also been greatly improved. The thermal insulation layer of the lining bricks uses blast furnace water-quenched slag diatomaceous earth powder or aluminum silicate refractory fiber felt to reduce heat consumption. Some vertical kilns have switched from burning coke to burning coal gas, natural gas or heavy oil, eliminating the pollution of fuel ash to the thermal system, while improving working conditions. In the 1970s, high-temperature vertical kilns with temperatures of ≥2200°C were also built;
[0004] However, the existing vertical kiln spray cooling water gun nozzle does not have the function of high temperature resistance during actual use, and the vertical kiln spray cooling water gun nozzle is easily damaged due to high temperature erosion during use. Therefore, we propose a high temperature resistant vertical kiln spray cooling water gun nozzle. Utility Model Content
