Description

一种煤气洗净水收集池及煤气洗净装置 技术领域
本实用新型涉及煤气处理的技术领域，具体涉及一种煤气洗净水收集池及煤气洗净装置。
背景技术
高炉是用钢板作炉壳，壳内砌耐火砖内衬。高炉本体自上而下分为炉喉、炉身、炉腰、炉腹、炉缸5部分。由于高炉炼铁技术经济指标良好，工艺简单，生产量大，劳动生产效率高，能耗低等优点，故这种方法生产的铁占世界铁总产量的绝大部分。高炉生产时从炉顶装入铁矿石、焦炭、造渣用熔剂(石灰石)，从位于炉子下部沿炉周的风口吹入经预热的空气。在高温下焦炭(有的高炉也喷吹煤粉、重油、天然气等辅助燃料)中的碳同鼓入空气中的氧燃烧生成的一氧化碳和氢气，在炉内上升过程中除去铁矿石中的氧，从而还原得到铁。炼出的铁水从铁口放出。铁矿石中未还原的杂质和石灰石等熔剂结合生成炉渣，从渣口排出。产生的煤气从炉顶排出，经除尘后，作为热风炉、加热炉、焦炉、锅炉等的燃料。高炉冶炼的主要产品是生铁，还有副产品高炉渣和高炉煤气。
然而，目前国内部分冶金企业为避免高炉煤气系统发生腐蚀，对干法除尘系统之后的高炉煤气在洗净塔内采用了喷淋碱液(洗净水)的工艺方案，该方案的主体设备即为煤气洗净塔。洗净塔内设有锥形收集池对洗净水进行初步回收之后，经水管送至循环水池。碱洗高炉煤气的耗水量较大导致收集池、循环水池等配置结构较大，且收集池 安装于基础面之上以及洗净塔之下，具体表现为洗净塔放置较高、单独收集池及循环水池占地较大等技术问题。是故亟待解决。
