Device for removing reaction heat generated in acrolein oxidation

The utility model discloses a device for removing reaction heat in the process of generating acrolein by oxidization reaction of propylene. The device comprises a reactor and two sets of fused salt regulators, wherein one set of fused salt regulators is connected with a reaction section of the reactor, and the other set of fused slat regulators is connected with a quenching section of the reactor; a steam drum is arranged between the two sets of regulators. An axial flow pump I is started in the reaction section; fused salt is fed from an inlet A2 of an bottom ring cavity F1 in the reaction section of the reactor; the fused salt flows through a baffle plate and then flows out of an outlet A1 of an upper ring cavity; the quantity of fused salt entering a boiler in the reaction section is controlled through a slide valve in the reaction section so as to form an independent cycle; an axial flow pump II is started in the quenching section; the fused salt is fed through an inlet A8 of a bottom ring cavity F2 in th
