Therefore, slag washing ponds, trenches and slag dumping ponds are serious sources of toxic water vapor pollution.
- Air curtain technology A high-power blower is used to artificially create an isolation layer above the slag trap. This technology seems to isolate the toxic steam in the slag pool, but in fact it only blows the toxic steam into the atmosphere (a very irresponsible approach to the environment!), and does not solve the pollution problem of toxic steam, and it is a one-time investment. Large, large power consumption, high operating costs (the blower consumes millions of yuan a year), and also increases the evaporation rate of the pool water, resulting in a lot of waste of water resources.

Description
本发明涉及一种高炉炉渣取送及渣池毒性水蒸汽污染治理综合系统，属于环境治理技术领域。
目前，钢厂高炉炉渣取渣一般是通过行车式捞渣机在捞渣池进行，取渣工作由人工操作的捞渣机完成。到了晚秋至早春时节，捞渣池上方蒸汽腾腾，能见度极低，工人的操作十分困难，并且存在极大的安全隐患。加上水蒸汽的毒性和高温，操作工人的操作环境十分恶劣。另外，平流式捞渣池取得的渣子往往为湿渣，湿渣在运往水泥厂的路上，会洒落很多毒水，对沿途的道路和环境造成极大的污染，并且不受水泥厂欢迎。
冲渣池、地沟和捞渣池是处理钢铁厂高炉炉渣的循环系统。炉渣靠水熄渣，该过程中会产生大量的含有各种酸性和碱性化学物质的水蒸汽，而这些水蒸汽往往被直接排放到大气中，产生液体PM2.5，严重污染空气,危害人类健康。故冲渣池、地沟和捞渣池是严重的毒性水蒸汽污染源。
现阶段，针对冲渣池、地沟的毒性水蒸汽污染问题(俗称白色污染)，国内已有一些研究和应用实例。捞渣池为敞开系统，毒性水蒸汽直接排至大气，而捞渣池的面积大，对大气的污染最大。但捞渣池部分的有毒水蒸汽污染，除了山东奇士登润滑科技有限公司的合成工业酸性水蒸汽阻隔剂方案外，目前尚无其它成熟的技术和方案，有的仅仅是概念性的，存在很多不足，具体现状如下：
(1)国内某知名大学提出的“地下巨型筛子”技术，每台高炉系统的造价高达1.3亿元人民币，且需高炉停工停产，尽管得到的为干渣，但并未解决污染问题，需要二次治理。
(2)气幕技术：利用大功率鼓风机在捞渣池的上方人为地制造一隔离层。此技术貌似将渣池的有毒蒸汽隔离开了，实则只是将毒性水蒸汽吹散到大气中(对环境很不负责任的做法！)，并没有解决毒性水蒸汽的污染问题，且一次性投资大，耗电量大，运行成本高(鼓风机一年耗电就高达数百万元人民币)，还加大了池水的蒸发速度，造成大量的水资源浪费。
(3)盖房子：在捞渣池上方盖一高大的房子，将捞渣行车等盖在里面，利用大功率引风机将水蒸汽引到二次治理的地方。该技术很难推广使用，主要原因如下：
A)房子太高，需要将渣池周边的地基进行专门的处理，投资大；
B)房内温度高达80-90℃，水蒸汽毒性又大，工人无法在房内进行捞渣工作；
C)引风机不可能将房内的毒性水蒸汽吸净，由其造成的负压只能加速池水的蒸发，从而造成大量的水资源浪费；
D)引风机耗电高，一台引风机每年需耗电近三百万元人民币，运行成本高。
E)被引风机抽走的蒸汽需要二次治理。
综上，市场亟需一种高炉炉渣取送及渣池毒性水蒸汽污染治理的技术方案。
