Aromatic hydrocarbon continuous catalytic nitration reaction device

The invention discloses an aromatic hydrocarbon continuous catalytic nitration reaction device. A feeding port (7) and a discharging port (8) are formed in the top of a reactor main body (1); a hollow shaft (2) is mounted on the axial line of the reactor main body (1); the top end of the hollow shaft (2) is communicated with a nitric acid storage tank (10) and a sulfuric acid storage tank (11) respectively; an aromatic hydrocarbon storage tank (9), the nitric acid storage tank (10) and the sulfuric acid storage tank (11) are communicated with the feeding port (7) respectively; the bottom end of the hollow shaft (2) is connected with a hollow worm wheel (6); a flow guide cylinder (3) and a deflection baffle (4) are mounted at the periphery of the hollow worm wheel (6) in the reactor main body (1) from the top down; a coiled heat exchange pipe (5) is mounted between the inner wall of the reactor main body (1) and the flow guide cylinder (3)/a deflection baffle (4); the whole body forms the reaction device. The aromatic hydrocarbon continuous catalytic nitration reaction device adopts a self-absorption mode without a liquid conveying device, and has the advantages of high reaction efficiency, high product quality, few byproducts, small release quantity of nitrogen oxide gas and environment-friendly process.
