锅炉引风机出口挡板移动式密封装置改造设计

Design Modification on the Mobile Sealing Device of the Outlet Baffle of Boiler Induced Fan

针对燃煤锅炉引风机出口挡板密封风机腐蚀严重的问题,研发了一种移动式引风机出口挡板密封装置,通过改变装置的布置、连接和投运方式,有效解决了密封装置因腐蚀而无法及时投运的问题,提高了设备的可靠性和使用寿命,保障了引风机检修工作的安全性,机组的经济性也得到进一步改善。

In allusion to the serious corrosion of outlet baffle sealed fan of a coal-fired boiler,a mobile fan outlet baffle sealing device is developed by changing the layout,connection and commissioning mode of the device,which effectively solves the problem that the sealing device cannot be put into operation in time due to corrosion,improves the reliability and service life of the equipment,ensures the safety of the maintenance of induced fan,and further improves the economics of the unit.
