Example Embodiment
[0024] Example 1
[0025] First, the TiCl produced from the fluidized bed 4 The gas passes through the dust collector for preliminary solid slag discharge; then, the TiAl intermetallic compound porous material is used as the filter element, and the TiCl 4 The gas is directly separated from gas and solid, and the filtration pressure is 0.002MPa. After filtering for 3 hours, use inert gas for backwashing. The backwashing pressure is controlled at 0.050MP and the backwashing time is 5 seconds. After the backwashing is completed, continue to filter. TiCl 4 The gas enters the leaching tower to be condensed and then enters the thickener to make the remaining liquid slag settle naturally to obtain TiCl with a solid content of 0.5% 4 product.

[0026] Example 2
[0027] First, the TiCl produced from the fluidized bed 4 The gas passes through the dust collector for preliminary solid slag discharge; then, the TiAl intermetallic compound porous material is used as the filter element, and the TiCl 4 The gas is directly separated from gas and solid, and the filtration pressure is 0.030MPa. After 4 hours of filtration, TiCl is used 4 The filtered air is backwashed, the backwash pressure is controlled at 0.050MP, and the backwash time is 10 seconds. After the backwash is completed, continue to filter, and the filtered TiCl 4 The gas enters the leaching and condensed, and then enters the thickener, so that the remaining liquid slag settles naturally, and TiCl with a solid content of 0.45% is obtained. 4 Product; in order to further improve TiCl 4 The purity of the liquid, the TiCl in the thickener 4 After the liquid overflows to the low-level storage tank, it is pressed into the high-level tank by a pressurizing pump, and a clot...

[0028] Example 3
[0029] First, the TiCl produced from the fluidized bed 4 The gas passes through the dust collector for preliminary solid slag discharge; then, the TiAl intermetallic compound porous material is used as the filter element, and the TiCl 4 The gas is directly separated from gas and solid, and the filtration pressure is 0.040MPa. After 6 hours of filtration, TiCl is used 4 The filtered air is backwashed, the backwash pressure is controlled at 0.090MP, and the backwash time is 8 seconds. After the backwash is completed, continue to filter, and the filtered TiCl 4 The gas enters the leaching tower to be condensed and then enters the thickener to make the remaining liquid slag settle naturally to obtain TiCl with a solid content of 0.5% 4 Product; in order to further improve TiCl 4 The purity of the liquid, the TiCl in the thickener 4 After the liquid overflows to the low-level storage tank, it is pressed into the high-level tank by a pressure pump, and the TiAl interm...
