| 中文摘要: |
| 葛洲坝嘉鱼水泥有限公司现有5 000 t/d新型干法水泥生产线HMMC224-2*10袋式收尘器粉尘排放浓度控制在≤30 mg/m³以下，运行阻力偏高，进出口压差最高达到1 550 Pa左右。为响应国家环保要求，我公司2025年初年度检修期间对窑尾袋式收尘器进行改造。文章详细介绍了对收尘器、清洁室及滤袋的改造，改造后整体收尘器检修方便，漏风量减少，无积水腐蚀现象。改造后的收尘器风量能满足提产后（6 200 t/d）的废气处理能力，设备运行阻力小于1 000 Pa，粉尘排放量排放小于10 mg/m3，实现了粉尘超低排放，满足环保及生产要求。 |
| 英文摘要: |
| The existing 5 000 t/d new dry-process cement production line at Gezhouba Jiayu Cement Co., Ltd. is equipped with an HMMC224-2*10 bag filter, which controls dust emissions at ≤30 mg/m³ but suffers from high operational resistance, with the maximum inlet-outlet pressure differential reaching approximately 1 550 Pa. To comply with national environmental requirements, the company carried out a renovation of the kiln tail bag filter during the annual maintenance period in early 2025. This article introduces the modifications made to the filter, cleaning chamber, and filter bags. After the renovation, the overall maintenance of the filter became more convenient, air leakage was reduced, and there was no water accumulation or corrosion. The upgraded filter’s air volume meets the exhaust gas treatment capacity after the production increase (to 6 200 t/d), with an operational resistance of less than 1 000 Pa and dust emissions below 10 mg/m³. This achieves ultra-low dust emissions, fulfilling both environmental and production requirements. |
