Liquid state magnesium chloride pelletization and particle classification collection equipment and method

Abstract

The invention relates to a liquid state magnesium chloride pelletization and particle classification collection equipment and method. The pelletization and particle classification collection equipmentcomprises a pelletization channel, a pelletizer, a driver, a classification collection channel and fluidization units. According to the liquid state magnesium chloride pelletization and particle classification collection equipment, liquid state magnesium chloride in the pelletizer flies out of the pelletizer due to a function of centrifugal force and move facing to the inner wall of the pelletization channel to change into magnesium chloride spherical particles then enters the classification collection channel, and controls the air injection speed of air injectors of the pelletization units to enable solid core magnesium chloride spherical particles and hollow core magnesium chloride spherical particles to correspondingly discharge from magnesium chloride spherical particle outlets corresponding to a first fluidization unit and a second fluidization unit. The liquid state magnesium chloride pelletization and particle classification collection equipment and method can realize the classification collection of the solid core magnesium chloride spherical particles and the hollow core magnesium chloride spherical particles, and additional value of products of magnesium chloride is improved.

Description

technical field [0001] The invention relates to liquid magnesium chloride granulation and particle classification collection equipment and method. Background technique [0002] At present, the production method of sponge titanium is mainly magnesium thermal reduction method. The method is based on Mg and TiCl 4 As a raw material, the reduction reaction is carried out at a high temperature of 800-1000 ° C to form titanium sponge, and at the same time, MgCl is also produced. 2 . MgCl 2 Its melting point is 714°C, and the temperature when discharged from the reduction furnace is 820-890°C. Currently, liquid MgCl 2 The main treatment method is that the furnace is pressurized and discharged directly into the open collection tank, and then naturally cooled in the air. This method results in a large amount of latent and sensible heat not being recovered. Although the initial temperature of bulk magnesium chloride is relatively high, it is difficult to recover waste heat due ...
