【技术实现步骤摘要】
本技术涉及一种喷雾冷却装置,尤其涉及在恶劣的烟雾环境中进行大流量喷雾冷却的机械式自动装置,本技术可以根据实际工作要求实现喷嘴的快速启停,并对装置自身采取必要的保护措施。
技术介绍
在钢铁、化工等行业,一些生产工艺中需要对大流量的烟气、热风等气体进行快速冷却,冷却的方式普遍采用喷雾实施冷却降温。这种需冷却的气体有如下几个特点:1、温度高、流量大,冷却时需要的冷却水量较大;2、气体进口温度波动大,但出口温度必须控制在一定范围内,且气体常含可燃气体成分,存在爆燃危险,因此需要根据要求实现快速启停,短时间快速冷却,并且具有可靠的控制措施;3、烟气的含尘量大,高温灰尘粘结性大,一旦附着堵塞喷嘴,则烟气温度不能及时降低,轻则烧布袋,重则影响后续生产,甚至有发生爆炸的危险性;4、烟气的流速高,含尘量大,快速流动的含尘烟气极易磨损置入其中的喷嘴,甚至能打坏喷嘴。以炼钢电炉为例,一台150t电炉的烟气量为2X IO5 3X IO5NmVh,汽化冷却烟道出口温度为500°C 650°C,进入机力风冷器的温度不高于450°C,喷雾冷却需要将温度从650°C降至450°C,则需要的水量为30t/h。根据雾化原理,压力式雾化喷嘴的流量与直径的关系为:权利要求1.一种大流量喷雾冷却装置,其特征在于,所述冷却装置设置有筒状保护罩,保护罩一端带有锥形盖板,在盖板上开设有若干个喷雾孔;所述保护罩内部设置有喷嘴座,喷嘴座的形状与保护罩的锥形盖板相适配,喷嘴座上设置有与所述喷雾口相适配的雾化喷嘴;在所述保护罩的锥形盖板与所述喷嘴座之间设置有一块转盘,该转盘的形状与所述保护罩的锥形盖板相适配, ...
