[0002] In the prior art, general ultraviolet germicidal lamps or photocatalytic processors are equipped with ultraviolet lamps in a hollow quartz tube, and photocatalysts are coated on the surface of the irradiated tube body, and then according to the total output energy of the ultraviolet lamp and the irradiable To the total area of ​​the tube body with the photocatalyst, a certain proportion of the flow of liquid flows through the tube body, so that the living body in the liquid is irradiated by ultraviolet rays for direct sterilization or irradiated by the photocatalyst to generate OH free radicals, which can be photocatalyzed The effect of degrading organic pollutants; while the pipe body of the prior art is only a pipe for liquid circulation, and the liquid flow directly passes through the inside. Due to the limited flow rate, the liquid flow flowing inside the pipe body will appear uneven in speed In some cases, when some liquids containing organic pollutants and bacteria pass through at high speed, they will not be able to fully receive sufficient ultraviolet radiation and degradation of the photocatalytic layer, so the effect is not good, and when the liquid flows through the tube body, because the cross-section area The sectional area of ​​the inlet pipe is larger than that of the liquid inlet pipe, so the flow rate is slowed down, causing dirt to accumulate on the wall of the quartz tube, blocking and reducing the ultraviolet light transmission rate, which directly reduces the total energy of the photocatalyst receiving ultraviolet rays, resulting in a decrease in performance, while ultraviolet rays The aging of the lamp tube and the intensity of ultraviolet output cannot be measured visually, so it can only be measured by expensive instruments or estimated by the service time of the ultraviolet lamp tube, so the operation of the photocatalytic processor cannot be reliably guaranteed
