摘要： Apparatus for the continuous production of phosphoric acid from phosphate-containing rock and sulfuric acid, consisting of a reaction tank with a cylindrical side wall and a planar horizontal bottom and cover, wherein the improvement comprises a rigid vertical internal S-shaped baffle with one end smoothly merging into the said cylindrical side wall of the reaction tank and the other end freely projecting into the tank so as to permit of free circulation and flow of the reaction mixture from one side of the baffle to the other but dividing the reaction tank into two distinct zones.

摘要： 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.
