Abstract

The invention discloses a photocatalysis water purification device with the advantage that an encapsulated ceramic ultrafiltration membrane can achieve the self-cleaning function. The photocatalysis water purification device comprises a water inlet cabin body and a purification cabin body, wherein the water inlet cabin body is provided with a cavity; the cavity is provided with a water inlet opening and a water outlet opening; an impeller is also arranged in the cavity; the impeller is rotationally connected relative to the water inlet cabin body; the impeller is also in transmission connection with a rotating shaft of a power generator; the purification cabin body is provided with a cavity; a ceramic ultrafiltration membrane is also arranged in the cavity; an inner cavity formed in the ceramic ultrafiltration membrane communicates with the cavity only through membrane holes formed in the ceramic ultrafiltration membranes; an inner cavity formed in the ceramic ultrafiltration membrane communicates with a water collecting cavity with an outlet; the ceramic ultrafiltration membrane comprises a ceramic filtering plate and a titanium oxide nanometer hole membrane attached onto the ceramic filtering plate; an LED (light emitting diode) lamp is also arranged in the cavity; the power generator provides a power supply for the LED lamp.

Description

technical field [0001] The invention belongs to the technical field of water purification devices, and in particular relates to a photocatalytic water purification device. Background technique [0002] At present, there is a ceramic filter plate device with self-cleaning function, which includes a ceramic filter plate and a titanium oxide porous membrane. This kind of ceramic filter plate device is installed inside the shell. Usually, the shell is made of non-transparent material. The titanium oxide porous membrane has the function of degrading polymer pollutants. For this, it is necessary to remove the ceramic filter plate device and expose it to the sun. This causes inconvenience to use. Contents of the invention [0003] The purpose of the present invention is to provide a photocatalytic water purification device, which can enable the encapsulated ceramic ultrafiltration membrane to perform the function of self-cleaning. [0004] For solving the problems of the techn...
