高くしなければならなかつた。 By the way, the height of the demineralizer storage chamber 1 mentioned above is
Arrangement height of desalinators 2 and 3, height of shield 4,
It is necessary to take into account the height of the filter element 10 and the lifting height of the monorail hoist 9. Therefore, it was necessary to increase the height of the desalination chamber.
本発明の目的は、以上の点を考慮し、高さを低
くすることのできる構造の脱塩器収納室を提供し
ようとするものである。 An object of the present invention is to provide a demineralizer storage chamber having a structure that allows the height to be reduced in consideration of the above points.
