Recovered sand cooling system and recovered sand cooling method

摘要

PROBLEM TO BE SOLVED: To provide a reclamation sand cooling system and a reclamation sand cooling method which enable reclamation sand to be reliably cooled.SOLUTION: A reclamation sand cooling system 1 that cools reclamation sand and adjusts a water content of cooled reclamation sand is provided, comprising: a sand water content temperature measuring instrument 2 which measures a water content and a temperature of the reclamation sand; a control device 3 which decides a proper amount of addition of water which is an amount of water added to the reclamation sand; water spray cooling devices 4, 5 which add water of the proper amount of addition of water to the reclamation sand, and cool the same by an evaporative latent heat of water thereby obtaining the cooled reclamation sand; an air introduction device 6 which introduces air to the water spray cooling devices 4, 5; and an introduction air temperature/humidity measuring instrument 7 which measures a temperature and a humidity of introduction air which is introduced to the water spray cooling devices 4, 5. In the reclamation sand cooling system 1, the control device 3 decides the proper amount of addition of water based on the water content and the temperature of the reclamation sand and the temperature and the humidity of the introduction air.SELECTED DRAWING: Figure 1
