UV REACTOR FOR CHEMICAL REACTIONS AND USE THEREOF
An ultraviolet (UV) reactor for carrying out chemical reactions in a pumpable medium by means of UV. The pumpable medium may also be, where appropriate, a multi-phase medium. The UV reactor has a reactor chamber through which the medium can flow In a direction of flow from an inlet to an outlet. The reactor chamber is penetrated by a number of UV transparent jacket tubes, which are arranged one behind the other in the direction of flow. UV emitters are arranged within the jacket tubes for emitting UV radiation into the reactor chamber. The jacket tubes are arranged one behind the other and are interlocked against one another at an angle αin the circumferential direction of the reactor chamber.
