摘要/Abstract

摘要： 干熄焦一次除尘器运行多年后，存在入口膨胀节浇注料脱落、料位计频繁误报、水冷套管内套漏水及下灰不畅等问题。对一次除尘器工艺进行了优化和改进，入口膨胀节采用耐火砖砌筑，将静电容式料位计改为纯电阻型料位计，利用锅炉排污水冷却水冷套管焦粉，同时改进除尘灰外排方式。改进后，一次除尘系统运行更加稳定，干熄焦清洁环保生产水平得以提升。

Abstract:

After the CDQ primary deduster puts into operation for years,it would occur the problems such as castable flake-off at the inlet expansion joint,frequent false alarm of level indicator,internal leakage of water-cooling jacket and slow discharge of dust,etc..Measures have been taken to improve the primary deduster,i.e.the inlet expansion joint is made of refractory bricks,electrostatic capacitance type level indicator is changed to resistor type,coke breeze is cooled by boiler blowdown through water-cooling jacket and coke dust discharge method is modified.After the improvement,the primary dedusting system can run in a stabler level and the CDQ unit can be in a more environmental-friendly operation.

Key words:

"> CDQ, Expansion joint, Primary deduster, Level indicator, Water-cooling jacket tube
