Design of crystallized salt discharge method

The crystallized material in the system is discharged to the thickener through the discharge pump, and the thickener is discharged to the centrifuge for solid-liquid separation. The internal material of thickener is concentrated brine, which is the mixture of crystals and mother liquor, constituting a supersaturated solution system, the crystal particles in the solution are dispersed uniformly, the large particles are formed due to gravity to settle to the bottom of the kettle, and the fine particles are suspended in the solution, which is stirred by the stirring paddle and overflows to the mother liquor tank and then back to the system. The large crystals are discharged to the centrifuge through the discharge valve, we design and verify the discharge method.

A-Self-control cut-off ball valve + self-control regulating globe valve (steam automatic flushing) discharge form

B-Manual ball valve + self-control regulating shut-off valve (automatic steam flushing) Discharge form

C-automatic cut-off ball valve + manual shut-off valve (automatic steam flushing) discharge form

D-Manual ball valve + manual shut-off valve (steam manual flushing) discharge form

E-automatic upward spreading valve + manual ball valve (steam manual flushing) discharge form

According to the design requirements and customer control requirements, you can choose the appropriate discharge method to achieve stable discharge;
