Embodiment 1
[0052] This embodiment provides a kind of equipment for preparing catalyst slurry, such as figure 1 Shown include
[0053] The primary powder-liquid shear mixing system is connected to the slurry feed port 8 set on the upper side wall of the solvent buffer tank 1 and the stirring tank 2;
[0054] The secondary powder-liquid shear mixing system is connected to the slurry outlet 17 set at the bottom of the stirring tank 2 and the slurry input port set on the upper side wall of the catalyst mixing tank 3;
[0055] The primary powder-liquid shear mixing system has a catalyst feed system 5;
[0056] The top of the stirring tank 2 is provided with a solvent feed port 9, and the bottom of the catalyst mixing tank is provided with a slurry output port.
[0057] The equipment adopts two-stage powder-liquid shear mixing, and the first-stage powder-liquid shear mixing system is used to transport the solid-liquid medium to the mixing tank 2, so as to avoid the catalyst powder from formi...
Embodiment 2
[0079] Embodiment 2 uses the equipment of the present invention to prepare catalyst slurry
[0080] (1) Inject 90°C coal tar solvent into the solvent buffer tank, then output from the solvent buffer tank, and enter the Venturi suction pipe through the solvent booster pump, and then feed the catalyst in the Venturi suction pipe with the catalyst sucked through the Venturi suction pipe The solid catalyst of the system is sheared and mixed together to obtain a catalyst slurry;
[0081] (2) Put the catalyst slurry output by the primary powder-liquid shear mixing system into the mixing tank for re-mixing, and then pass into the secondary powder-liquid shear mixing system for shear mixing. The particle size range of the solid particles in the mixing tank is 5 μm~ 500μm, the temperature in the stirring tank is 90°C, the slurry concentration in the stirring tank is 0.1%, the pressure in the stirring tank is normal pressure, and the solid content at the inlet of the secondary powder-li...
Embodiment 3
[0083] Embodiment 3 uses the equipment of the present invention to prepare catalyst slurry
[0084] (1) Fill the wax oil solvent at 60°C into the solvent buffer tank, then output it from the solvent buffer tank, and enter it into the Venturi suction pipe through the solvent booster pump, and then feed the catalyst in the Venturi suction pipe with the catalyst sucked through the Venturi suction pipe The solid catalyst of the system is sheared and mixed together to obtain a catalyst slurry;
[0085] (2) Pass the catalyst slurry output by the primary powder-liquid shear mixing system into the stirring tank and mix again in the stirring tank, and then pass into the secondary powder-liquid shear mixer for shear mixing, and the solid particles in the stirring tank The diameter range is 5 μm to 500 μm, the temperature in the mixing tank is 60°C, the slurry concentration in the mixing tank is 5%, the inside of the mixing tank is normal pressure, and the solid content at the entrance o...
