Photocatalytic reactor and method for treating gaseous pollutants using the same

摘要

The present invention provides a photocatalytic reactor and a method for treating gaseous pollutants using the same, which can decompose and remove gaseous pollutants such as volatile organic compounds (VOCs), odors, etc. as well as liquid pollutants using an environmentally friendly photocatalytic reaction. To this end, the present invention provides a photocatalytic reactor including: a solution tank to which a fluid containing gaseous pollutants to be treated is supplied through an inlet; a solution injector installed at the top of the inlet and injecting a gaseous pollutant solution into the fluid to be treated such that the gaseous pollutants of the fluid are dissolved; and a liquid photocatalytic treatment device receiving the gaseous pollutant solution, in which the gaseous pollutants of the fluid are dissolved and liquefied, from the solution tank and decomposing the liquefied gaseous pollutants of the fluid.

1. A photocatalytic reactor comprising:
a solution tank to which a fluid containing gaseous pollutants to be treated is supplied through an inlet; a solution injector installed above the inlet which injects a gaseous pollutant solution into the fluid to be treated such that the gaseous pollutants of the fluid are dissolved; and a liquid photocatalytic treatment device receiving the gaseous pollutant solution, in which the gaseous pollutants of the fluid from the solution tank are dissolved and liquefied, then the liquefied gaseous pollutants are decomposed, wherein a porous filler is provided below the solution injector to increase contact time between the gaseous pollutants of the fluid and the gaseous pollutant solution, wherein a plurality of optical fibers are arranged parallel to each other at regular intervals and fixed between an inlet and an outlet of the liquid photocatalytic treatment device, and wherein a plurality of partial partitions are arranged at regular interval in a direction longitudinal to the optical fibers such that the optical fibers are inserted and fixed through holes of the partial partitions, and one end of each partial partition is fixed to one side of the photocatalytic treatment device and the other end has an opening through which the fluid to be treated passes.
