Vortex type ultraviolet sterilizer

Abstract

The invention discloses a vortex type ultraviolet sterilizer. The vortex type ultraviolet sterilizer comprises a shell (3) and an ultraviolet sterilizing lamp (12), wherein the ultraviolet sterilizinglamp (12) is located in the shell (3); the exterior of the ultraviolet sterilizing lamp (12) is sleeved by an ultraviolet-permeable quartz sleeve tube (4); a water passing channel (5) is formed between the shell (3) and the quartz sleeve tube (4); a plurality of flow guide plates (7) are arranged in the water passing channel (5); the outer edge of one side of each flow guide plate (7) is providedwith a flow guide opening (6) used for guiding a water flow to pass through; the flow guide openings (6) of every two adjacent flow guide plates (7) are located at different sides; and the inner wallof the shell (3) and / or the surface of each flow guide plate (7) are subjected to polishing treatment to form ultraviolet reflecting surfaces (8). Compared with a conventional ultraviolet sterilizer,the ultraviolet sterilizer provided by the invention increases the ultraviolet irradiance by 10% to 20%, and has better sterilizing effect.

Description

technical field [0001] The invention relates to ultraviolet sterilizing equipment in the field of water treatment, in particular to a vortex type ultraviolet sterilizer. Background technique [0002] In recent years, with the improvement of living standards, people have paid more and more attention to the safety of drinking water, and the awareness of healthy drinking water has gradually increased. Various types of water purifiers have also been recognized and promoted by people. At present, there are two main methods of physical purification of drinking water by water purifiers on the market, filter element filtration and ultraviolet sterilization. In the process of ultraviolet sterilization, the problem that the industry generally cannot overcome is that the sterilization rate is low. The main reason is that the current general-purpose ultraviolet sterilizers are often straight-through, and the water flows out from the outlet along a straight line after entering the water ...

AI Technical Summary

Problems solved by technology

In the process of ultraviolet sterilization, the problem that the industry generally cannot overcome is that the sterilization rate is low. The main reason is that the current general-purpose ultraviolet sterilizers are often straight-through, and the water flows out from the outlet along a straight line after entering the water inlet. The time of the ultraviolet sterilizer is often very short, so that the bacterial microorganisms are not exposed to sufficient ultraviolet radiation dose

However, considering the design structure and cost of the water purifier, if the method of increasing the volume of the ultraviolet sterilizer to improve the sterilization effect also has limitations
