FJS-1A型地质钻探废浆处理设备的研制

Development of FJS-1A geological drilling waste slurry treatment equipment

为了处理在地质钻探过程中产生的废弃冲洗液,结合废弃冲洗液处理工艺流程,开展了FJS-1A型废浆处理设备总体结构设计,介绍了设备的工作原理和主要性能参数。室内试验与青海共和干热岩钻探项目野外试验结果表明,FJS-1A型废浆处理设备所设置的破胶絮凝模块能有效破坏冲洗液的稳定体系,并使固液分层。固液分离模块能有效分离固相和废水,氧化模块能有效处理废水,最终处理废水可达国家污水二级排放标准,满足地质钻探废弃冲洗液的处理需求,实现了一人一机一键操作。该设备的成功研制为绿色勘查提供了有力的支撑。

In order to treat the waste drilling fluid produced during geological drilling,the overall structure design of the waste slurry treatment equipment FJS-1A is carried out in combination with the waste drilling fluid treatment process flow.The working principle and main performance parameters of the equipment are introduced.The laboratory test and field test results of Qinghai Gonghe Dry‑heat Rock Drilling Project show that the gel breaking flocculation module set by the waste slurry treatment equipment FJS-1A can effectively destroy the stable system of drilling fluid and separate the solid‑liquid.The solid‑liquid separation module can effectively separate the solid phase and waste water,and the oxidation module can effectively treat the waste water.The final treated waste water can reach the national sewage secondary discharge standard and meet the treatment requirements of waste drilling fluid in geological drilling.The successful development of this equipment can provide some reference for green exploration.
