1. A reaction system for preparing butyraldehyde by propylene carbonylation, characterized in that, comprising:
a reactor, a propylene storage tank, a carbon monoxide storage tank, a hydrogen storage tank, a propylene pipeline and a synthesis gas pipeline; a side wall of the reactor is sequentially provided with a propylene inlet and a synthesis gas inlet from top to bottom;
two micro-interface generators are arranged inside the reactor from top to bottom, and the micro-interface generator located at a top is connected with the propylene inlet to break the propylene gas into micron-scale micro-bubbles; the micro-interface generator located at a bottom is connected with the synthesis gas inlet for breaking the synthesis gas into micron-scale micro-bubbles; outlets of the two micro-interface generators are opposite, and the outlets are connected with a gas distributor for evenly distributing raw materials;
the propylene inlet is connected to the propylene storage tank through the propylene pipeline, the carbon monoxide storage tank is connected in parallel with the hydrogen storage tank, and both the carbon monoxide storage tank and the hydrogen storage tank are connected to the synthesis gas inlet through the synthesis gas pipeline; both the propylene pipeline and the synthesis gas pipeline are provided with bubble generators for pre-dispersing and breaking the gas into bubbles;
wherein the gas distributor comprises a distributor body and a plurality of nozzles; the plurality of nozzles is obliquely arranged on the distributor body for uniformly dispersing the micro-bubbles generated by the micro-interface generators;
wherein a catalyst inlet is arranged on the side wall of the reactor, and a sprayer is arranged in the reactor and the sprayer is located at a top of the micro-interface generator; the sprayer is connected to the catalyst inlet; and the catalyst inlet is connected with a catalyst storage tank.
