Quench cooler for cooling hot flowing gas

摘要

The cooler has a cylindrical cover (10) which is connected to a hot gas conduit (7) via a gas inlet connection (11), and to a cold gas conduit (9) via a gas outlet connection (12). Water sprays (30) upstream a filler body column (13) filling out the flow cross-section of the cover. The column is a cartridge with its own casing (14) insertable into the cylindrical cover. It is provided with thermocouples (25). The column also has thermocouples (26,27) upstream and downstream of it and which are arranged in the flow cross-section. The sprays are pressure atomising nozzles, which are fed with water and water vapour. The water vapour is produced in an evaporator (17), which is arranged in the hot air conduit.
