The invention relates to a device for drawing off liquid salt, particularly for facilities for purifying wastewater, said device comprising a heating chamber. The heating chamber comprises an inlet for introducing a salt-containing substance and is connected to an outlet for a salt melt. The outlet comprises an outlet channel and an outlet channel end, a cooling region for cooling the salt melt being provided downstream of the outlet channel end. The outlet channel is peripherally surrounded by an outlet wall at least along a section, the outlet comprising a heating element.

Proposed is a fines removal apparatus installed on a radioactive liquid waste granulator, the apparatus including: a body unit fastened to an outlet provided on the radioactive liquid waste granulator and configured to receive the granulated radioactive waste by an operation of a first opening/closing valve, the radioactive liquid waste granulator being configured to manufacture concentrated liquid waste and to manufacture granulated radioactive waste by drying the concentrated liquid waste. an air supply unit provided on one side of the body unit and configured to spray air to the supplied granulated radioactive waste at regular periods, thereby scattering and separating fines contained in the granulated radioactive waste; and a reprocessing unit provided in a vacuum state on an opposite side of the body unit and configured to allow the scattered fines to be transferred to the radioactive waste granulator along a transfer pipe by vacuum pressure.

Carbonate salts are efficiently produced from carbon dioxide in exhaust gas. The method for producing carbonate salts includes an atomizing step that forms an aqueous alkaline solution mist with an atomizer; a mixing step that mixes exhaust gas with the aqueous alkaline solution mist produced in the atomizing step to absorb exhaust gas carbon dioxide in the mist and combine mist positive ions with the carbon dioxide to produce mist that contains carbonate salt; and a separating step that separates the mist that contains carbonate salt produced in the mixing step from exhaust gas.

A removable insert and a spray nozzle which includes the removable insert and a nozzle cap. The removable insert has a base member and a protruding member. The nozzle cap has an annular flange which delimits an interior locating surface for the insert. The flange extends radially and ends with an internal extremity which defines a planar spray opening. When in use, the base member is housed within the nozzle cap whilst the protruding member projects outwardly and stands proud of the planar spray opening.
