Description

technical field [0001] Based on physical methods, photothermal theory, photoelectric theory and thermodynamic principles, the present invention proposes a photovoltaic-driven ultraviolet lamp sterilizing solar water heating device. It involves ultraviolet light sterilization technology, solar heat utilization technology, photoelectric conversion technology and heat exchange technology. Background technique [0002] The traditional fossil energy resources are increasingly depleted, and the environment is seriously polluted in the process of utilization, which restricts the sustainable development of the world economy. At the same time, people's demand for energy is increasing day by day, and it has become an important strategic material. In this case, the use of renewable energy is an inevitable trend, especially solar energy as an "inexhaustible, inexhaustible "New energy sources such as safety, energy saving, and environmental protection have attracted more and more attent...

Problems solved by technology

[0007] The advantages of using ultraviolet lamps to sterilize domestic water are: (1) high sterilizing efficiency and very short sterilizing time. For example, the sterilizing time for several common bacterial viruses such as mold spores and algae is within one second, and the sterilizing efficiency is as high as 99%; (2) No secondary pollution; (3) No biological immunity, ultraviolet sterilization is to destroy the DNA of microbial genetic material, interfere with its replication and transcription, make it lose its reproductive ability and then inactivate it, which belongs to physical method of sterilization; (4) Broad-spectrum sterilization (5) High operational safety, low operation and maintenance costs, easy installation and operation, small footprint, continuous large-scale disinfection, etc. However, ultraviolet light sterilization also cannot provide remaining disinfection capabilities and bacterial regeneration and The problem of re-pollution. The traditional ultraviolet lamp sterilization device causes a certain waste of UV dose and uneven sterilization. This patent uses an integrated device of ultraviolet lamp and water tank, which belongs to the closed ultraviolet sterilization device. The change should make the water flow in the reactor as much as possible. The traditional design concept of forming a plug flow inside to fully accept the radiation, puts forward a new concept: use its own structure to make the ultraviolet energy more evenly distributed in the water body, and does not make special requirements for the flow of water. At the same time, the new domestic hot water standard (GB5749-2006) added detection and limit values ​​for Giardia and Cryptosporidium in the microbial indicators, which undoubtedly played a huge role in promoting the application of ultraviolet technology in water treatment in China.
