Sea sand purification system
The invention discloses a sea sand purification system, which belongs to the field of sea sand purification, and comprises a flushing device and a sand-water separation device, the flow flushing device comprises an inlet, an outlet and a flow flushing channel, the inlet is used for adding a sand-water mixed solution formed by fully mixing sea sand and water, the flow flushing channel is used for flushing the sand-water mixed solution in the flow flushing channel from the inlet to the outlet at a certain flow flushing speed, and the outlet is used for discharging the sand-water mixed solution; and the sand-water separation device is used for carrying out sand-water separation on the sand-water mixed liquid discharged from the outlet of the flushing device, and discharging harmful substances which are removed from the sea sand and enter the water along with the water. Harmful substances on the surface of the sea sand and in fine seams and pores can be fully removed, the chemical binding activity of a sand body and a cementing material is improved, the chlorine ion content of the purified sea sand can be reduced to 0.0002%-0.002%, the sea sand is reduced into river sand before entering the sea, concrete reinforcement corrosion and concrete deterioration cannot be caused after the purified sea sand is used, and the service life of the sea sand is prolonged. Durability is good and cost is low.
本发明公开了一种海砂净化系统，属于海砂净化领域，包括冲流器和砂水分离装置；冲流器包括入口、出口和冲流通道，入口用于加入由海砂和水充分混合形成的砂水混合液，冲流通道用于使得砂水混合液在冲流通道内从入口向出口以一定的冲流速度进行冲流，出口用于排出砂水混合液；砂水分离装置用于对从冲流器的出口排出的砂水混合液进行砂水分离，将从海砂上去除并进入水中的有害物质随水一同排放。本发明能够将海砂表面上和细缝、孔隙内的有害物质充分清除，提高砂体与胶凝材料化学结合活性，净化后海砂的氯离子含量可降至0.000％～0.002％，达到将海砂还原成入海前河砂的状态，净化后的海砂使用后不会导致混凝土钢筋锈蚀和混凝土劣化，耐久性好，成本低廉。
