Problems solved by technology

On the other hand, much of the research on light pipes at home and abroad is still in the continuous strengthening and improvement of their own performance. In fact, no system exists in isolation, and the research on light pipe systems also needs to be considered in combination with other systems. For example, natural ventilation systems, etc., combined with new technologies can not only improve the performance of the light pipe but also expand its application range

Embodiment

[0020] Experimental equipment: UV filter, quartz cuvette, Fresnel lens, Petri dish, coating rod, etc.

[0021] Experimental drug: R2A agar medium

[0022] Measurement parameters: HPC

[0023] Such as figure 2 As shown, after the sunlight is gathered by a Fresnel lens, it passes through a filter and irradiates on a quartz cuvette filled with fresh tap water, and the irradiation time is set at 500s, 950s, and 1500s. The exposure time is calculated as follows:

[0024] According to the test results of the sunlight ultraviolet intensity, the pass rate of the filter to the ultraviolet is about 0.42, and the transmittance of the Fresnel lens to the ultraviolet is about 0.26. Assume that the UV intensity in sunlight is 0.01 mW / cm 2 , after passing through the Fresnel lens, the sunlight area is 38.47 cm 2 Concentrate to 1cm 2 size. Then the ultraviolet intensity in this area is 0.042 mW / cm 2 .

[0025] According to the "Ultraviolet Disinfection Standard", the dosage of ultra...

Abstract

The invention discloses a solar water supply pipe network ultraviolet sterilization device which comprises a plurality of sunlight sterilization pipes installed in series. The side wall of each sunlight sterilization pipe is communicated with one end of a light pipe, the other end of the light pipe is provided with a light filter, two Fresnel lenses in opposite directions are arranged on one side of the light filter, the light filter is positioned on a focusing light path of the two Fresnel lenses, each sunlight sterilization pipe is further provided with a prism, and the Fresnel lenses are automatically controlled by a controller to track the sun. By combining electric energy with solar energy, the device has the advantages of environmental protection and no pollution.

Description

technical field [0001] The invention relates to a solar-type ultraviolet sterilizing device for a water supply pipe network, in particular to a high-efficiency water quality treatment device for sterilizing a water supply pipe network with intelligent control and no pollution using solar energy and light guide technology. Background technique [0002] At present, ultraviolet systems have been widely used in municipal sewage treatment in my country. Designers have a deep understanding of the design and selection of ultraviolet systems used in sewage treatment, and have accumulated a lot of valuable experience. However, the application of ultraviolet systems in water supply plants has just started in China, and currently only a few municipal water plants in China have set up ultraviolet disinfection processes. "Drinking Water Hygienic Standards" (GB 5749-2006) clearly lists two insects (Giardia and Cryptosporidium) as target microorganisms for water treatment disinfection, whi...
