A heat preservation and dissipation device for a large cover in titanium sponge production comprises a reactor and the large cover. A magnesium oxide heat preservation layer is arranged in the large cover, and the granularity phi of magnesium oxide is larger than or equal to 5 mm and smaller than or equal to 10 mm. A pipeline C connected through a flange A and a pipeline B connected through a flange B are arranged above the large cover, a valve A is arranged on the pipeline B, sealing gaskets are arranged on the flange B and the flange A correspondingly, and a filter screen B is further arranged on the flange B. The other end of the pipeline C is connected with a storage tank, and a filter screen A and a baffle are arranged in the storage tank. A pipeline A connected with the pipeline B isconnected to the upper part of one side of the storage tank, a valve B is arranged on the pipeline A, and a water ring pump is connected to the other side of the pipeline A. The pipeline B is furtherconnected with a pipeline D, the other end of the pipeline B is connected with a draught fan, and the pipeline D is provided with a valve C. The technical problem of large cover heat dissipation in the reduction period in the titanium sponge production process is solved, and in the reduction period, no heat preservation layer is arranged in the large cover, and forced ventilation and heat dissipation are conducted through the draught fan.
Description
technical field [0001] The invention relates to a heat preservation and heat dissipation device for a large cover in the production of sponge titanium. Background technique [0002] The production process of titanium sponge mainly includes the reduction and feeding production stage and the distillation production stage. Most of the domestic and foreign industrial production of sponge titanium adopts the method of reducing titanium tetrachloride with magnesium, and directly feeds titanium tetrachloride into the large cover system of the closed vessel reactor combined with the reactor and the large cover, and contacts with the liquid surface of molten magnesium. A thermochemical reaction occurs, and the temperature of the reaction point reaches above 1200°C, and a large amount of heat is released during the production of the reduction stage. Sponge titanium is produced in the distillation stage. It is produced at a high temperature of 1000°C and a high vacuum environment. The...
