采用煤气干法除尘装置的高炉炉顶压力控制系统
摘要：
本发明提供了一种采用煤气干法除尘装置的高炉炉顶压力控制系统，包括煤气放散塔、煤气干法除尘装置、净煤气管网和TRT系统，其还包括粗煤气减压阀组、净煤气减压阀组和TRT静叶/快开调节阀组，以及分别控制这三种阀组的粗煤气减压阀组控制模块、净煤气减压阀组控制模块和TRT静叶/快开调节阀组控制模块。本发明根据切换条件，可自动实现三套顶压控制设备之间的相互切换，切换过程能够实现高炉炉顶压力的稳定。
摘要（英）：

The invention provides a blast furnace top pressure control system adopting a gas dry-method dust-removal device, comprising a gas-diffusing tower, a gas dry-method dust-removal device, a clean gas pipe network, a TRT system, a rough gas pressure relief valve group, a clean gas pressure relief valve group, a TRT stator blade/quick adjustment valve group and three valve group control modules respectively controlling the three valve groups, i.e. a rough gas pressure relief valve group control module, a clean gas pressure relief valve group control module and a TRT stator blade/quick adjustment valve group control module. The invention can automatically and mutually switch the three top pressure control devices according to switching conditions, and the stable blast furnace top pressure in the switching process can be realized.
