氯化钾速溶装置的设计与应用

Design and application of KCl quick dissolving device

氯化钾是压裂液配制中防膨剂的主要成分,在添加氯化钾时,常出现下料不畅、溶解不充分等问题,物料溶解量达不到设计要求,影响配液质量。针对出现的问题,提出喷淋加搅拌的方式解决下料问题,采用射流混合加提升搅拌的方法解决溶解问题,从而达到氯化钾快速溶解的目的,可以达到"随配随溶",提高了配液中固体添加剂的溶解速度。2016年以来,速溶装置在多个压裂液配液站应用,工艺流畅,设备可靠性高,满足了业主使用要求,对压裂液精细化配液提供了有力支持。

KCl is the main component of the anti-swelling agent in preparation of fracturing fluid. When adding KCl, there are many problems such as poor discharge and inadequate dissolution. So the amount of the material dissolving can not meet the design requirements,the quality of solution is not up to the standard. Aiming at the existing problems,this paper puts forward spraying and mixing to solve the discharging problem, and solves dissolving problem by the method of jet flow mixing and lifting agitation, so as to achieve the purpose of rapid dissolution of KCl, and improve the dissolution rate of solid additive in liquid. Since2016, the quick dissolving device has been applied in many fracturing fluid preparation stations. The process is smooth and the equipment is reliable, which satisfies the owner's requirements and provides strong support for fine fluid preparation technology of fracturing fluid.
