The invention discloses a device and method for removing reaction heat in a 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 the fused salt regulators is connected with a reaction section of the reactor, and another set of the fused slat regulators is connected with a quenching section of the reactor; a steam drum is arranged between the two sets of regulators. The method comprises the following steps: starting an axial flow pump in the reaction section; feeding the fused salt through an inlet A2 of an F1 bottom ring cavity in the reaction section of the reactor; enabling the fused salt to flow through a baffle plate and then flow out of an outlet A1 of an upper ring cavity; controlling the quantity of fused salt entering a boiler in the reaction section through a slide valve in the reaction section, in order to form an independent cycle; starting another axial flow pump in the quenching section; feedi
