中国石油网消息：8月29日，从川庆钻探获悉，该公司自主研发的《高温高压稠化仪导热油循环过滤系统装置》，正式获得国家知识产权局发明专利授权。

China Oil News: On August 29th, Chuanqing Drilling announced that the company's independently developed "Thermal Oil Circulation and Filtration System Device for High Temperature and High Pressure Thickening Instrument" has officially obtained an invention patent authorization from the National Intellectual Property Administration.

为解决导热油废液处理长期存在的难题，川庆钻探技术团队采用“离心+加压”双级过滤装置设计，先将废导热油进行高速离心旋转，初步脱除大部分固相杂质，然后进入加压过滤阶段，通过向封闭腔体内注入高温高压气体，驱动油液穿过多层滤层，完成二次精密过滤，最终净化后的油品汇集于下腔，实现有效回收利用。

To address the long-standing problem of treating waste heat transfer oil, the technical team of Chuanqing Drilling adopted a dual-stage filtration device design of "centrifugation + pressurization". Firstly, the waste heat transfer oil was subjected to high-speed centrifugal rotation to initially remove most of the solid-phase impurities. Then, it entered the pressurized filtration stage. By injecting high-temperature and high-pressure gas into the sealed cavity, the oil was driven to pass through multiple filter layers, completing a second level of precise filtration. Finally, the purified oil was collected in the lower chamber, achieving effective recycling and utilization.

应用数据显示，“离心+加压”双级过滤装置可将导热油更换周期延长2至3倍，年均节约耗材及维护费用超10万元，不仅降低了生产成本，而且减少了废弃物排放，实现经济效益与环保效益兼顾。

Application data shows that the "centrifugal + pressurization" two-stage filtration device can extend the replacement cycle of the heat transfer oil by 2 to 3 times, saving over 100,000 yuan in consumables and maintenance costs annually. This not only reduces production costs but also decreases waste emissions, achieving a balance between economic benefits and environmental benefits.
