To defoam with blower fan in connection with defoamer,the foam that cannot be naturally eliminated in the black liquor can be led into the black liquor by differential pressure,and then naturally defoamed with defoamer,and the remnant foams after defoaming can be sucked with the blower fan and further treated in a seperator.

In this paper,aperture defoamer is introduced,which belongs to the mechanical method and tests are set up on test-bed indoor with defoaming rate of 86%.

The application of blower fan in the defoaming of black liquor tank in the extraction section;
