Example 1
A filter cake dehydration method for novel coal gasification comprises the following steps:
a. taking a ceramic filter, evacuating the inner cavity of the ceramic plate to ensure that the inside of the cavity is in a vacuum state, and generating air pressure difference between the inside and the outside of the cavity;
b. placing the material in a material groove at the upper end of the ceramic plate, and adsorbing the material on the ceramic plate under the action of negative pressure;
c. the solid-liquid mixture of the materials in the material tank is always stirred by the stirring rod, the solid materials cannot be intercepted above the ceramic plate through the microporous ceramic plate, and the liquid smoothly passes through the gas-liquid distribution device under the action of vacuum pressure difference and the hydrophilicity of the ceramic plate;
