摘　　要：针对油田生产中悬浮细颗粒污泥处理难的实际情况,介绍了研制的适用于石油石化企业的快速污泥处理工艺。由于在实际应用中浓度变化和工人操作可能造成浓缩段流道堵塞的现象,基于PLC技术设计了一套压力自适应系统。该系统可以实现压力变化的自动识别、系统流程的自动切换和自动恢复,可以根据需要设定压力限制范围、时间节点和动作顺序。该套压力自适应系统的实现为快速污泥处理装置的安全稳定运行提供了保证。这一方法也为今后环保设备模块化配置时的系统安全提供了解决途径。A set of rapid sludge treatment equipments were introduced in this paper which can deal with the suspended and fine sludge in oil and petrochemical enterprise efficiently.But blocking phenomenon would happen in the section of concentrating separator because of changing of thickness or worker’s wrong operation. The self-adapting pressure controlling unit was designed to solve this puzzle. It can inspect the pressure fluctuation and switch the work flow on/off automatically,and can set its pressure range,time interval and motion sequence as required. It can ensure security and stabilization of the whole process of the rapid sludge treatment equipments and can be regarded as one of the necessary conditions to configurate the modular environmental protection processes.
