The invention provides a component and a method for overcoming the deposition of particles on a horizontal pipeline of heat exchange equipment. Through mounting a component consisting of a washer and a guide blade in the horizontal pipeline of the heat exchange equipment, liquid and solid phases generates spiral flow when flowing across the guide blade by means of kinetic energy provided by the liquid and the solid phases flowing into the horizontal pipeline to overcome the deposition phenomenon generated under the gravity action when the particles flow in the horizontal pipeline. Meanwhile, with the adoption of the component, the scale prevention property, the descaling property and the heat exchange property of the heat exchange equipment are improved, and the cleaning frequency of the heat exchange equipment is reduced. The component can be widely applied to the field of energy sources, chemical industry, pharmacy, sea water desalination and the like.
