SU117582A1 - Continuously operating apparatus for vapor phase dehydrogenation - Google Patents

Description

A continuously operating apparatus for vapor phase dehydrogenation, for example, borneols, with induction heating, consisting of a metering shut-off feeder, an evaporator and a dehydrator, is known.

The described continuously operating apparatus of the same designation, as compared with the known, speeds up the dehydrogenation process and allows to obtain higher quality products. This is achieved by making a contact dehydrator for vapor phase dehydrogenation of two heated cylinders, the annular space between which is filled with a catalyst. Heating of the evaporator and contact dehydrator is carried out by means of an induction device.

The drawing shows a diagram of a continuously operating apparatus.

The hopper 1 has a disintegrating device 2 in the lower part, which is a shaft with blades arranged in a shakhmat order.

The dosing feeder 3 is made in the form of a two-disk self-cleaning device and is a gate preventing the outflow of gases.

The evaporator 4 is made in the form of a hollow cylinder with a conical bottom, equipped with a loading hatch 5, to which the dosing feeder 3 is connected, the pressure gauge 6 clamp, the thermocouple clamp 7 and the 8 clamp to drain contaminated residues.

The contact dehydrator for vapor phase dehydrogenation consists of a heated outer cylinder 9 and a heated inner cylinder 10. The annular space 11 of the dehydrator is filled with a catalyst and covered with a grille 12 at the bottom. The outer cylinder 9 has four manholes 13 for unloading the catalyst and is equipped with three fittings for thermocouples 14 , fitting 15 for the release of camphor vapors and two devices 16 for additional loading of the catalyst during operation of the apparatus installed on the top cover of contact part no. 117582-2 -

hydrator and consisting of a check valve, screw, flywheel and side hatch.

Inside the cylinder 10, a metal element 17 is inserted, consisting of a cut-out on one side along the entire length of the stainless tube, inside which there is a core of transformer iron. Copper wire is wound on the outer surface of the stainless tube.

Copper wire 18 is wound on the outer surface of cylinder 9, as well as on the surface of evaporator 4, to which a voltage of 60 V is connected. Heating of the evaporation and contact zones carried out by induction heating. The electrical part of the apparatus consists of a step-down transformer 19 and starting equipment 20.

The metering feeder 3 and the shaft of the disintegrating device 2 are driven by the engine 21, the variator 22 and the gearbox 23.

The mass to be treated, such as borneol, is loaded into the hopper 1, where it is loosened and then fed to the metering feeder 3. From the feeder 5, the borneol in the required amount is sent to the evaporator 4, passes in vapor form through the catalyst and is dehydrated into the camphor. Camphor in vapor form is directed to condensation.
