Fly ash treatment for chemical liquid supplying method and fly ash treatment for chemical supply equipment

摘要

PROBLEM TO BE SOLVED: To use a float type flowmeter in order to know the flow rate of a high viscosity chemical liquid even if a fly ash treatment chemical liquid is a high viscosity chemical liquid.;SOLUTION: In this method for supplying the fly ash treatment chemical liquid for supplying the fly ash treatment chemical liquid to a kneader 4 for kneading fly ash with the fly ash treatment chemical liquid by the kneader 4 to form a fly ash treatment material constituted so as to prevent the elution of heavy metals in fly ash, a first chemical liquid storage tank 101 for storing the first fly ash treatment chemical liquid supplied to the kneader 4, a second chemical liquid storage tank 102 for storing the high viscosity fly ash treatment chemical liquid supplied to the kneader 4 and a dilution water storage tank 103 for storing the diluting water supplied to the kneader 4 are provided. The first chemical liquid sent out of the first chemical liquid storage tank 101 to be passed through a first float type flowmeter 106 and the high viscosity chemical liquid sent out of the second chemical liquid storage tank 102 are allowed to meet with each other to be guided to a second float type flowmeter 108 provided to the pipeline L101 communicating with the kneader 4.;COPYRIGHT: (C)2009,JPO&INPIT
