Attendance water concentrated system and attendance water concentrated method

摘要

With the coal seam gas being the attendance water concentrated system which has the evaporation method thickener 18 which concentrates the attendance water which is discharged from green coal zone, as for the cooling system which cools the aforementioned evaporation method thickener 18, for the indirect heat exchanger the chilled water 36 which is used 28 which cools the aforementioned evaporation method thickener 18 and cooling well 68 or it takes in water from reservoir, 34 the chilled water supply expedient 38 which is supplied to the aforementioned indirect heat exchanger 28, or, well 68 or either of the abolition warm water sending back expedient 40 which is reset to reservoir 34 it forms the abolition warm water 44 after the cooling in the closed circuit which consists of one side. Because of this, after using with evaporation method thickener 18, special equipment in order to process chilled water 36 is not needed.
