Multi-bed axial and radial reactor

The invention discloses a multi-bed axial and radial reactor. The reactor comprises a radial cylindrical sealed pressure-bearing shell (2), an air inlet pipe (16), an axial-radial catalytic reaction zone (8) and an air outlet pipe (14), wherein the axial-radial catalytic reaction zone (8) is a cylindrical containing space capable of containing catalyst beds; the containing space is formed by side walls (11), a top seal head (5) and a seal bottom (18); the side walls (11) and the alternative seal bottom (18) are of an opening structure through which fluid can penetrate but solid catalysts cannot penetrate; and the top seal head (5) is of a fluid impenetrable structure. The pressure of the reactor is reduced, the space utilization rate is high, and any gas flow deviation or short-circuit phenomenon is avoided. 本发明公开了种多床层轴径向反应器，该反应器包括径向圆筒形密封承压壳体(2)、进气管(16)、轴径向催化反应区(8)、以及出气管(14)；所述轴径向催化反应区(8)为可容纳催化剂床层的圆筒形容纳空间，该容纳空间的外壳由侧壁(11)、顶部封头(5)和封底(18)形成，其中所述侧壁(11)以及可选择地所述封底(18)为流体可透过但固体催化剂不可透过的开孔结构，所述顶部封头(5)为流体不可透过结构。该反应器压降低
