Title:
TREATMENT METHOD OF MOISTURE-CONTAINING BULK MATERIAL, AND FLOCCULANT ADDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/187539
Kind Code:
A1
Abstract:
A method is provided which, even when continuously adding a polymer flocculant to moisture-containing bulk material conveyed on a conveyor belt, enables using simpler equipment to more uniformly add the polymer flocculant to moisture-containing bulk material. This treatment method of moisture-containing bulk material, which involves adding a flocculant to moisture-containing bulk material conveyed on a conveyor belt, involves: using as the aforementioned flocculant a liquid dispersion that contains a polymer flocculant in a salt solution in a dispersed state; using a tube-shape member installed above the conveyor belt and having outlets which are provided in the peripheral wall along the long axis direction and which let the liquid dispersion flow out in the width direction of the conveyor belt; and adding the liquid dispersion from the outlets in the tube-shape member onto the moisture-containing bulk material on the conveyor belt.
