摘要:
The photoreactor comprises a tube bundle (10) made up of numerous capillary tubes (11) through which a reaction medium flows. The tubes (11) are transparent. Solar radiation or artificial radiation acts upon the reaction medium for effecting a photochemical or photobiological treatment. The inlet chamber (12) connected with the tube bundle (10) comprises a flow distributor (16) which distributes the reaction medium from the fluid inlet (15) to the tubes (11). The flow distributor (16) allows for a smaller volume of the inlet chamber (12). The reactor volume, which is not irradiated, is thus reduced, and the efficiency of the rector is enhanced.

摘要:
The present invention relates to a device and method for introducing solar radiation energy into a photoreactor. This reactor can be employed for performing photochemical or photobiological reactions, i.e., syntheses, decontamination, disinfection and treatment processes. The device is characterized in that the photoreactor consists of one or more transparent outer tubes irradiated with light from the exterior, the reaction medium being passed through the tubes and thereby exposed to the radiation, wherein one or more empty transparent tubes with a smaller diameter are provided in the interior of said outer tubes, especially in a concentric arrangement, and the reaction medium is passed through the gap formed between an outer and an inner tube or, in the case of several inner tubes, through the gaps formed therebetween.
