Title:
WATER CONTENT MEASUREMENT METHOD, WATER CONTENT MEASUREMENT DEVICE, AND MANUFACTURING METHOD FOR COKE
Document Type and Number:
WIPO Patent Application WO/2024/063081
Kind Code:
A1
Abstract:
Provided are: a water content measurement method capable of reliably measuring a water content of a measured object, even when a layer thickness of the measured object fluctuates; a water content measurement device; and a manufacturing method for coke. The water content measurement method includes: a microwave measurement step of, when transmitted microwaves are transmitted to a measured object S by a microwave transmission unit 11 that moves relative to the measured object S, receiving, by using a microwave reception unit 12, the transmitted microwaves that have passed through the measured object S as received microwaves, and finding the attenuation thereof and the phase difference between the transmitted microwaves and the received microwaves; a bulk density calculation step of calculating an amount of the measured object S, a movement speed of the measured object S relative to the microwave transmission unit 11, and the bulk density of the measured object S on the basis of the layer thicknesses of the measured object S; and a water content calculation step of calculating a water content of the measured object S using the phase difference, the attenuation, and the bulk density measured by a microwave evaluation unit 13.
