Title:
BULK DENSITY DETECTION METHOD AND DEVICE, WATER CONTENT CALCULATION METHOD AND DEVICE, AND METHOD FOR PRODUCING COKE
Document Type and Number:
WIPO Patent Application WO/2024/063082
Kind Code:
A1
Abstract:
Provided are a bulk density detection method and device, a water content calculation method and device, and a method of producing coke that enable highly accurate detection of bulk density without needing to use a special device. This bulk density detection method is for emitting microwaves at an object and detecting the bulk density of the object, said method comprising: a microwave emission step for emitting emission microwaves of each of a plurality of wavelengths at the object; a microwave receiving step for receiving the emission microwaves, having been transmitted through the object, as reception microwaves for each of the plurality of wavelengths; an attenuation amount calculation step for calculating, for each of the plurality of wavelengths, an attenuation amount that is the difference in energy between the emission microwaves and the reception microwaves; a wavelength identification step for extracting a wavelength distribution of the attenuation amounts that is based on a predetermined regular wavelength distribution, with regard to the relationship between the calculated attenuation amounts and the wavelengths corresponding to the attenuation amounts, and also identifying, in the wavelength distribution, a predetermined representative wavelength included in the regular wavelength distribution; and a bulk density detection step for detecting the bulk density of the object on the basis of the identified representative wavelength.
