Description

Technical Field

[0001] The present invention relates to the technical field of dehydrogenation reaction, and more particularly to a dehydrogenation reaction device. Background Art

[0002] Propane dehydrogenation refers to the process of producing propylene monomer by dehydrogenating propane. It is an important way to produce propylene.

Through the pressure detector and the temperature detector, people can easily detect the pressure and temperature inside the sandwich reactor body. The air inlet pipe is convenient for the input of propane. The electric heater can heat the inside of the sandwich reactor body through the electric heating wire, so as to improve the efficiency of the reaction. The air outlet pipe is convenient for the output of the gas after the reaction. The first valve can control the output of the gas.

[0050] Working principle: When the dehydrogenation reaction device is in use, the staff starts the first motor 4, and the first motor 4 drives the transmission shaft 9 to rotate, and the transmission shaft 9 drives the two cams 17 to rotate. Through the relative arrangement of the protruding ends of the two cams 17, the protruding ends of the cams 17 can push the material barrel 14 to tilt at the rotation point of the first universal ball 13 during the rotation process, and make the catalyst inside the material barrel 14 shake, so that the contact area between the catalyst and the gas is increased to a certain extent, so that the catalytic speed of the catalyst to the gas is increased to a certain extent, and the transmission shaft 9 can drive the transmission ring 12 to rotate around the power gear 15 inside the support ring 10 through the power gear 15, and realize the rotation of the material barrel 14, so that the catalyst inside the material barrel 14 can be disturbed, so that the propane gas can react more fully with the catalyst, and to a certain extent, the speed of the propane dehydrogenation reaction is guaranteed to a certain extent;

[0051] When the first rotating shaft 5 rotates clockwise, the inclined surface provided on the L-shaped positioning frame 31 enables the first rotating shaft 5 to push the L-shaped positioning frame 31 to slide out of the fixing groove 30 when rotating clockwise, thereby realizing the independent rotation of the first rotating shaft 5. When it is necessary to clean the filter plate 34, the first motor 4 drives the first rotating shaft 5 to rotate in the opposite direction. Under the action of the spring 32 on the L-shaped positioning frame 31, the first rotating shaft 5 drives the L-shaped positioning frame 31 to rotate through the fixing groove 30, so that the L-shaped positioning frame 31 drives the transmission plate 6 to rotate, and the transmission plate 6 drives the transmission roller 38 to rotate through the cleaning plate 7, and the transmission roller 38 drives the power transmission shaft 35 to rotate through the worm 39 and the worm gear 37.
