Abstract : the paper presents the application of esp on the jiant electric titanium slag furnace and demonstrates the feasibility of esp for dust collection on electric titanium slag furnace 文摘:介绍了电收尘器在大型钛渣电炉上的应用，论证了钛渣电炉烟气静电收尘的可行性。
To avoid dust pollution , an impulse bag filter will be used to collect dust from crusher and discharging points of belt conveyor . purified air will be drained to the atmosphere 为避免粉尘污染，破碎车间设有气箱脉冲袋收尘器一台，抽取破碎机及带式输送机下料处的含尘气体，经收尘器净化后的气体由排风机排入大气。
Hot waste gas from grate cooler is divided into four parts : part of it is sent to kiln as secondary air , part of it is sent to decomposition furnace as burning air by tertiary duct , and the rest is drained to the atmosphere after purified by electric dust collector at kiln head 出篦冷机高温废气一部分作为窑用二次空气入窑；一部分由三次风管送到分解炉作为燃烧空气；剩余废气经窑头电收尘器净化处理后排入大气。
By use plc , system can complete function as follow : this auto - control system be applicable to the temperature and smoke and dust the deal the variety quick , control the process is difficult with the operation is ; by the temperature controlor can automatically follow to the wet tower " exit temperature , error in the ? 3 v including ; by to automatically spray fog to lower the electric resistance , with the function for full the electricity equipment accepting the dust ; because of adopting feedback closed loop , and come to a to respond to the speed quick , constant temprature control the accuracy is high ; because of adopting the sensors , and make the system circumstance to leak water quick ; system have many control parameter can set exit control temperature and adjust value low limit by key ; can communication with remote computer and have remote control 通过使用plc ，使该自控系统可以完成如下功能：适用于温度及烟尘量变化快、控制过程难以操作的场合；通过温控表自动跟踪增湿塔出口温度，误差达到3以内；通过自动喷雾来降低粉尘比电阻，以此充分发挥电收尘器的作用；由于采取了闭环反馈回路，达到了响应速度快，恒温控制精度高；通过使用各种检测传感器，使得异常情况泄水快；该自控系统具有多套控制参数，增湿塔出口控制温度及调节阀下限值可通过按键设定；可与上位机通讯，具有“现控远控”功能。
