Fluidized bed alcohol dehydration reaction device
A fluid bed reactor used for preparing ethene from dehydrated alcohol is in the shape of a barrel with an upper cover, and is divided into an upper part and a lower part by a horizontal partition plate at the middle and lower part of the barrel. The upper part was covered with a multi-layer vertical separation sleeve, which was divided into a cylindrical reaction chamber, a ring-shaped heating chamber, and a ring-shaped heat-resistant greenhouse in turn. The cylindrical reaction chamber is a separated hollow cylinder that can be lifted up. The rock wool layer in the cylinder divided the cylinder into a catalyze dehydration layer and a glass bead zeolite layer. The cylinder is equipped with a movable upper cover and a lower bottom directly connected to the cylinder. A small hole is arranged at the center of the upper cover to extend a heating couple into the catalyst, and another small hole is installed with an air outlet pipe. The ring-shaped heating chamber is composed of an electric heating wire and an electric heating wire fixing sleeve, the sleeve is made of a fire-resistant insulation material, the inner diameter of the sleeve is greater than the outer diameter of a hollow cylinder which can be separated from the reaction chamber, and the outer wall of the electric heating wire fixing sleeve is provided with a spiral groove for fixing the electric heating wire; the ring-shaped heat-insulation chamber is composed of a sleeve made of an asbestom and a fire-resistant insulation material, the ring-shaped sleeve is positioned between the outer wall of the reactor and the ring-shaped heating chamber, and the space between the outer wall of the reactor and the ring-shaped sleeve is filled with the asbestom.
