Problems solved by technology

However, because the set ultraviolet lamp is above the water, only a part of the ultraviolet rays can directly sterilize the water; and the ozone produced only works on the surface of the water. If the water body is thicker, the underground water cannot be purified.

Embodiment Construction

[0013] The following further describes the utility model with reference to the drawings and embodiments.

[0014] Please refer to Figure 1, which is a schematic diagram of an embodiment of the ultraviolet water purification device of the present invention. The ultraviolet water purification device has a reaction tank 1 with a certain amount of water in the reaction tank 1 and an irradiation tube 2 is arranged in the water perpendicular to the water surface. A low-pressure discharge tube 21 (only one is shown in the figure) is installed in the above-mentioned irradiating tube 2, and the low-pressure discharge tube 21 can emit ultraviolet rays with wavelengths of 253.7NM and 184.9NM. The irradiation tube 2 is made of transparent material, which can irradiate the ultraviolet light emitted by the low-pressure discharge tube 21 on the water body. Since the irradiation tube 2 is arranged inside the water body, the ultraviolet rays can be irradiated to the water body in the largest area ...

Abstract

The invention relates to a water purification installment with ultraviolet radiation, at least includes the reactor, its characteristic lies in that the reactor is equipped with irridating tube and one circulation cooling tube, the low atmospheric pressure discharge tube is in the irridating tube , one air feeder and one trachea one end enters in the above illumination hall, leaves the trachea another end connection and enters the reactor, which shine in the hall the mix and has the ozone air-input in the reactor of the water purification, which revolves the illumination tube establishment to have the light catalyst piece group. In the illumination hall has send out the purple outwire discharge tube, the discharge tube's send out is lower than 290NM ultraviolet radiation The reactor has induction pipe and inputs the chlorine together with water, the promotion oxidation.

Description

Technical field [0001] The present invention relates to a water purification device, in particular to an ultraviolet water purification device that uses ultraviolet rays and ozone and photocatalyst technology generated by ultraviolet rays to irradiate the air to eliminate and purify bacteria in water. Background technique [0002] Existing devices that use ultraviolet light (UV for short) to kill germs in water, such as the product of Shanghai Light Industry Machinery No. 7 Factory, are equipped with a UV lamp above a closed container. Under the ultraviolet lamp, the two ends of the container are equipped with water inlet and water outlet respectively. Water flows in from the water inlet and flows out from the water outlet after being irradiated by ultraviolet rays. This structure is only sterilized by ultraviolet radiation, and the water is deformed, Carcinogenic and mutagenic organic matter is difficult to remove. [0003] In view of the above defects, a solution has been produ...
