摘要
本文主要针对在五氧化二钒生产过程中一种副产铬资源的工业应用中出现煅烧窑附属布袋收尘器布袋使用寿命降低的问题,经收集煅烧尾气分析,煅烧时生成酸性气体腐蚀收尘布袋,为降低腐蚀气体含量,通过对比工业水逆洗、工业水浆洗两种方法,结果表明,工业水五级逆洗脱除率高于一次浆洗,但存在过滤速度慢、增加固态的流转等不足.通过在生产线中,增加副产铬资源洗涤工序,大大降低其酸性离子含量,使煅烧窑收尘布袋使用寿命由半年提升至 2 年,每年降低成本约 27 万元.
Abstract
This article mainly focuses on the problem of reduced service life of the bag filter attached to the calcination kiln in the industrial application of a by-product chromium resource in the production process of vanadium pentoxide.After collecting and analyzing the calcination exhaust gas,acidic gas is generated during calcination to corrode the dust collection bag.In order to reduce the content of corrosive gas,by comparing the two methods of industrial water reverse washing and slurry washing,the removal rate of industrial water fifth stage reverse washing is higher than that of prima-ry slurry washing.However,there are shortcomings such as slow filtering speed and increased solid-state flow.By adding a washing process for by-product chromium resources in the production line,the acidic ion content is greatly re-duced,and the service life of the calcination kiln dust collection bag is increased from half a year to 2 years,reducing costs by about 270 000 yuan per year.
