Because fixed bed 5 itself and send warm pipe 3 to belong to and dismantle the connection, through letting send warm pipe 3 cover fixed bed 5, can utilize to send warm pipe 3 to resist the impact of material, let the impact force that fixed bed 5 received less, help protecting fixed bed 5 itself and fixed bed 5 and send the connected state of warm pipe 3. Moreover, after the temperature conveying pipeline 3 is used for buffering, the materials can generate turbulent flow and enter from all directions of the fixed bed 5 more easily, and the materials are matched with the catalyst, so that all surfaces of the catalyst are contacted with the materials more uniformly.
In order to make the catalyst distribution more uniform and the cooperation with the material better, the spoiler formed by the temperature-sending pipeline 3 extends upwards from the bottom along the axial direction of the reactor body on the inner wall of the reaction kettle 1. This setting can let the catalyst all have the distribution about in reation kettle 1, and distributes more evenly, need not be like among the prior art, need let the material evenly dispersed in the material through high-speed stirring.
Preferably, the stirring blades of the stirrer 2 are straight plates, the extending direction of the straight plates corresponds to that of the stirring shaft, the side surfaces of the straight plates are fixed with the stirring shaft, and the temperature conveying pipeline 3 and the fixed bed 5 are positioned between horizontal lines at two ends of the straight plates.
