US 2017/0176109 A1 · SOLUTION CONVEYING AND COOLING APPARATUS

Abstract

To provide a solution conveying and cooling apparatus that enables removal of a deposit of solid material, or a fouling deposit, inside the apparatus with extremely simple work equipment by fewer on-site workers in a short tune without any dangerous work such as hydroblasting. The solution conveying and cooling apparatus has a rigid outer tube for a cooling medium and a plurality of rigid outer tubes for solution arranged parallel to each other inside the rigid outer tube for a cooling medium. A thin inner tube is disposed inside each of the rigid outer tubes for solution, this thin inner tube having an outer diameter smaller than an inner diameter of the rigid outer tube for solution at normal temperature and pressure, and expanding by an increase in at least one of temperature and pressure of a solution conveyed and as a result contacting with an inner surface of the rigid outer tube for solution that is cooled by the cooling medium.
