Suspension crystal washing equipment and method

The invention provides suspension crystallization washing equipment and method, the suspension crystallization washing equipment comprises a raw material slurry pipeline, at least four washing tanks, a finished product tank, a residual liquid pipeline and a finished product pipeline, and the operation process comprises the following steps: a, unloading; step b, feeding; step c, final-stage washing; step d, intermediate washing; and e, primary washing: during operation, at least one washing tank is in the steps a and b, one washing tank is in the step c, one washing tank is in the step e, and the other washing tanks are in the step d. Compared with a mechanical washing tower of existing washing equipment, the suspension crystallization washing equipment disclosed by the invention does not relate to a dynamic sealing device; compared with existing centrifugal machine washing equipment, the purification effect is good, and the equipment manufacturing cost and difficulty are remarkably reduced. 本发明提出了一种悬浮结晶洗涤设备及方
