Spiral photoreactor

A helical photoreactor (1), comprising:

• at least one lamp module (10);
• at least one tube coil (20), which has a plurality of tube windings (23, 23a, 23b) between an input section (21) and an output section (22), the at least one tube coil (20) being arranged around the at least one lamp module (10);
• a carrier device (30), which carries the at least one tube coil (20);
• a protective housing (40),
• wherein the protective housing (40) surrounds a receiving space (38′),
• wherein the carrier device (30) with the at least one tube coil (20) and the at least one lamp module (10) are arranged in the receiving space (38′), and
• wherein the carrier device (30) provides a predetermined positioning of the at least one tube coil (20) with respect to the at least one lamp module (10) and the protective housing (40);
• and
• at least one elongated guide element (33), which is present in the protective housing (40) parallel to a longitudinal axis, the longitudinal axis being defined by the at least one lamp module (10),
• wherein the carrier device (30) has at least one engagement element (31),
• wherein the at least one engagement element (31) is arranged on the at least one elongated guide element (33) so as to be capable of being guided in a longitudinally movable manner and so as to be capable of being positioned,
• wherein the at least one elongated guide element (33) specifies a positioning of the carrier device (40) with the at least one tube coil (20) by the at least one engagement element (31) guided on the at least one elongated guide element (33).
