Description
技术领域 technical field
本实用新型涉及一种用于冶金炉渣水碎的喷嘴。The utility model relates to a nozzle used for crushing metallurgical slag.
背景技术 Background technique
冶金行业冶金高温炉渣的水碎，一般采用开放管或带筛网的传统喷嘴，使水流冲击高温炉渣，达到水碎、冷却炉渣的目的。但是，传统喷嘴的打散和冲渣力量不足，造成热炉渣附着在溜槽壁上冲不走，热渣淤积到一定程度后，热量大量积聚，使水瞬间大量汽化，从而发生爆炸。传统喷嘴只能满足小渣量(50t/h以下)的水碎，在中等渣量(60～70t/h)时，经常性发生放炮事故(俗称“放炮”)。而在较高炉渣(70t/h以上)时，该喷嘴水碎效果更差，易造成未冷却的炉渣在溜槽内结渣，发生爆炸事故，轻则炸坏溜槽等设施，重则伤及职工身体安全，给安全生产带来较大威胁。The water crushing of metallurgical high-temperature slag in the metallurgical industry generally adopts an open pipe or a traditional nozzle with a screen to make the water flow hit the high-temperature slag to achieve the purpose of water crushing and cooling the slag. However, the traditional nozzles have insufficient power to disperse and wash slag, causing hot slag to adhere to the chute wall and cannot be washed away. After the hot slag deposits to a certain extent, a large amount of heat accumulates, causing a large amount of water to vaporize instantly, resulting in an explosion. The traditional nozzle can only meet the water crushing of small slag amount (below 50t/h), and when the slag amount is medium (60-70t/h), blasting accidents (commonly known as "blasting") often occur. However, when the slag is high (above 70t/h), the water crushing effect of the nozzle is even worse, and it is easy to cause the uncooled slag to slagging in the chute, resulting in an explosion accident, which may damage the chute and other facilities in the slightest, and injure the employees in severe cases. Physical safety poses a greater threat to safe production.
