ABSTRACT:
There is disclosed a reactor designed to produce phosphoric acid by wet process. The reaction vessel proper is a cylindrical body divided into two compartments by a sinusoidal wall. The first space formed inside by the cylindrical wall of the vessel and the sinusoidal one and by one curved segment joining them is semi-circular and serves as pre-mixer provided with a stirring device and a pocket to allow the fluid flowing down through the bottom to reach the reaction space overhead. The reaction vat has two compartments and provided with a series of stirring devices so located as to permit an efficient, intimate mixture of the reaction medium. The vat is integrally roofed by a tight cover with many orifices left in it fitted for connection sleeves, such as: supply, gas venting, sight holes, and manholes, etc. The reactor incorporates as an integral unit a space devoted to the pre-mixing of reactants and means to guide the reaction medium through the reaction vessel; in this way the retention time required for the reaction process and calcium sulphate crystallization is decreased.
