Air cooling device for large cover of titanium sponge I-type reactor

Abstract

The invention relates to an air cooling device for a large cover of a titanium sponge I-type reactor, which comprises a cover plate, air cooling areas are distributed on the left side and the right side of the cover plate, one air cooling area is provided with an air inlet, the other air cooling area is provided with an air outlet, the middle part of the cover plate is provided with a feed port, an air distribution plate is arranged below the cover plate through a connecting plate, and the air distribution plate is provided with an air outlet. The air inlet and the air outlet penetrate through the air distribution plate, the air inlet is located above the air distribution plate, air distribution plate outlets are evenly formed in the air distribution plate, a guide plate is vertically arranged between the upper side of the air distribution plate and the cover plate on the lower side of the air inlet, and a temperature measuring opening is formed in the bottom of the cover plate. The device can monitor and reduce the surface temperature of the large cover, avoids high-temperature deformation, improves the feeding speed, shortens the reduction reaction time, and is high in safety coefficient.

Description

Technical field [0001] The present invention belongs to the field of sponge titanium equipment manufacturing technology, specifically relates to an air-cooled device for a large cover of sponge titanium type I reactor. Background [0002] In the production of sponge titanium by the Klauer method, the reduction-feeding semi-combined process is adopted, which mainly refers to the use of "I" type semi-combined reactor to carry out the reduction distillation reaction to produce sponge titanium, which is characterized by the installation of the distillation reactor after the reduction is completed, the upper condenser, the lower is the still; In the prior art, due to the high temperature of the reactor lid in the reduction stage, about 850 ° C, the feeding speed is slow and the reduction reaction time is long; In addition, the surface temperature of the large cover is high, and the high temperature causes the deformation of the large cover to be serious, which seriously shortens the s...

Problems solved by technology

[0002] In the process of producing sponge titanium by the Krall method, the reduction-distillation semi-combined process is adopted, which mainly refers to the use of "I" type semi-combined reactors to carry out reduction distillation reaction to produce sponge titanium, which is characterized in that it is carried out after the reduction is completed. For the installation of the distillation reactor, the upper part is the condenser and the lower part is the distiller; in the prior art, due to the high temperature of the reactor cover in the reduction stage, about 850°C, the feeding speed is slow and the reduction reaction time is long; in addition, the large The surface temperature of the cover is high, and the high temperature leads to serious deformation of the large cover, which seriously shortens the service life, and increases the difficulty of combining with the distillation reactor after deformation, which poses a safety risk; in view of the above problems, the present invention provides a method that can monitor and reduce Temperature, avoid high temperature deformation, increase feeding speed, shorten reduction reaction time, air cooling device with high safety factor for the large cover of sponge titanium type I reactor
