【摘要】：在水泥熟料生产过程中,生料在分解炉内的分解是一个复杂的物理化学反应。由于生料流量波动大且生料边界条件频繁变化,生产过程经常处于异常工况,导致预热器C5出口温度高于上限,致使预热器C5下料管堵塞造成生产停产。为了解决上述问题,提出了一个具有前馈补偿的温度智能切换控制策略,由分解炉温度和预热器C5出口温度协调控制器、异常工况控制器和切换机制组成。实际应用结果表明,所提出的控制策略能够根据当前工况的变化选择正确的控制器,并且使生产远离故障工况。
[Abstract]:In the process of cement clinker production, the decomposition of raw material in calciner is a complex physical chemical reaction. Because the raw material flow fluctuates greatly and the raw material boundary condition changes frequently, the production process is often in abnormal working condition, which leads to the temperature of the outlet of the preheater C5 being higher than the upper limit, resulting in the blockage of the preheater C5 discharge tube and the production stoppage. In order to solve the above problems, a temperature intelligent switching control strategy with feedforward compensation is proposed, which consists of a coordinated controller for calciner temperature and C5 outlet temperature of preheater, a controller for abnormal working conditions and a switching mechanism. The practical application results show that the proposed control strategy can select the correct controller according to the change of the current working conditions and make the production away from the malfunction condition.
