The invention discloses a titanium sponge forced heat dissipation device and method, belongs to the technical field of titanium sponge production equipment. The problem of reactor necking deformationcaused by frequent start and stop of an exhaust fan in a high-speed feeding section of reaction in the prior art is solved. The titanium sponge forced heat dissipation device comprises a reduction furnace and a reactor, the reactor is arranged in the reduction furnace, the reduction furnace is provided with an air inlet and an air outlet, the air inlet is connected with an air inlet pipeline, a fan is arranged at one end of the air inlet pipeline, the air outlet is connected with an air outlet pipeline, the reactor is provided with a feeding pipe, a feeding device is connected to one end of the feeding pipe, and the feeding pipe is further provided with a flow meter. According to the continuously-forced heat dissipation device and method, the air inlet amount is controlled according to thefeeding speed of titanium tetrachloride, and heat generated by reaction is accurately and timely discharged out of a system, so that the deformation of the reactor caused by cold and hot impact is avoided, and the quality of titanium sponge is improved.
Description
technical field [0001] The invention relates to the technical field of titanium sponge production equipment, in particular to a device and method for forced heat dissipation of titanium sponge. Background technique [0002] In the process of producing sponge titanium by magnesia thermal method, the magnesia thermal reduction of titanium tetrachloride is a strong exothermic reaction. During the reduction production period, the maximum temperature at the center of the reactor (4) will exceed 1200°C. If the waste heat generated by the reduction reaction is not discharged in time, the internal and external quality of titanium sponge will be affected, the production cycle of titanium sponge will be prolonged, and the production cost will be increased. Regardless of the I-type furnace or the U-type furnace in domestic sponge titanium production enterprises, the heat dissipation methods include forced heat dissipation and natural heat dissipation, but most of them use forced heat d...
