1. An ion-exchange equipment comprising: a tank unit formed by a sidewall having open top and bottom ends and defining a cooling liquid flow-in port, a top member received in the open top end and defining a cooling liquid flow-out port, and an imperforate bottom member received in the open bottom end, wherein inner surfaces of the sidewall, top member, and imperforate bottom member of the tank unit define an ion-exchange chamber, and wherein the inner surface of the bottom lid closes a bottom end of the ion exchange chamber;
an ion-exchange resin in form of particles filling the ion-exchange chamber of the tank unit such that the filling rate does not exceed 88.8% of the volume of the ion exchange chamber, wherein the ion-exchange chamber is provided so as to extend along an axial direction of the tank unit and the ion-exchange chamber has a circular cross section taken perpendicularly to the axial direction of the tank unit, and the cooling liquid flow-in port is formed so as to extend in a tangential direction of the ion-exchange chamber, wherein the cooling liquid flow-out port is provided with a cylindrical member that is disposed within the ion-exchange chamber and is spaced radially inwardly from the inner surface of the sidewall, the cylindrical member extending downwardly from the cooling liquid flow-out port toward the inner surface of the imperforate bottom member such that a lower end of the cylindrical member is opposed to the inner surface of the imperforate bottom member. |
