Description

High-efficiency over-flow ultraviolet disinfection equipment

technical field

The utility model relates to a high-efficiency overflow ultraviolet disinfection equipment, which belongs to the technical field of water quality treatment.

Background technique

Faced with increasingly serious water pollution and backward water purification technology, coupled with the secondary pollution of the municipal pipe network, the safety and health of tap water in China has become a major issue related to people's livelihood; nowadays, more and more people People began to pay attention to the health of drinking water, and the optimization of tap water came into being. After the optimization of the water body, how to ensure the freshness and sterility of the water quality is an urgent problem to be solved in the process of water quality optimization. At present, domestic tap water optimization mainly includes bottled water and bottled water, small household water purifiers and pipe-based water supply; bottled water, bottled water and small household water purifiers generally do not have terminal sterilization technology, and cannot Bacterial growth is controlled; the sterilization technologies used in pipeline water supply mainly include chlorine disinfection, ozone sterilization and ultraviolet disinfection. Chlorine disinfection is a water treatment disinfection method commonly used in my country, but chlorine is also harmful to the human body. It cannot be ignored; the bactericidal effect of ozone varies greatly due to different types of microorganisms, but ozone is very easy to decompose, and can usually be decomposed into oxygen at normal temperature and pressure; at this stage, common ultraviolet disinfection equipment is divided into over-flow type and submerged. Ultraviolet sterilizers can sterilize, mainly relying on ultraviolet rays. Ultraviolet rays are a kind of light waves invisible to the naked eye. They exist outside the ultraviolet end of the spectrum, so they are called ultraviolet rays. According to different wavelength ranges, they are divided into three types: A, B, and C. Among them, the C-band ultraviolet wavelength is between 240 and 260nm, which is the most effective germicidal band. The strongest wavelength in the band is 253.7nm. When the various bacteria, viruses, microorganisms, parasites or other pathogens are irradiated by ultraviolet light UV-C, the DNA and RNA in the cell tissue are destroyed, thereby preventing the regeneration of daughter cells. The ultraviolet disinfection equipment is not in use In the case of any chemical agent, it can kill more than 99.9% of bacteria and viruses in water, liquid or air in a short period of time (usually 0.2~5 seconds); scientific experiments have proved that ultraviolet rays with a wavelength of 240~280nm have high efficiency. Sterilization function.

Among them, the submerged ultraviolet sterilizer mainly includes ultraviolet lamps, electronic ballasts, quartz sleeves and connectors; this type of sterilizer can effectively act on the liquid and residual air in the water tank, and can effectively prevent secondary pollution , to maintain the cleanliness of the water tank, it is more suitable for industries that require time-based and segmented water supply, such as water supply by quality, electronics, pharmaceuticals, food, and cosmetics; Convenience, high sterilization rate and other characteristics. It is the first choice for disinfection of high-level water tanks, outlets of water storage tanks, and inlets of centralized water supply frequency conversion pumps; it is more suitable for engineering, but it is difficult to apply to the end of small household water purifiers. The over-flow ultraviolet sterilizer mainly includes ultraviolet lamps, electronic ballasts, quartz sleeves, stainless steel chambers and connectors; it is a simple ultraviolet sterilizer, suitable for small water dispensers, Ro pure water systems, and direct drinking water systems Water disinfection is mainly used in household drinking water, small pure water plants, small mineral water plants, drinking fountains, etc.; however, there are problems such as short contact time between water flow and ultraviolet lamps, and the sterilization effect is limited.

Utility model content

(2) Technical solutions

The high-efficiency over-flow ultraviolet disinfection equipment of the present utility model includes a stainless steel cavity, which is made of food-grade stainless steel to ensure that the water body is hygienic and clean; the inside of the stainless steel cavity is provided with a quartz sleeve to protect the ultraviolet lamp and The ultraviolet light has a high light transmittance; the quartz casing is equipped with an ultraviolet lamp tube, and the ultraviolet light is used to kill bacteria in the water body; a double-helix water inlet and outlet quartz tube is installed between the stainless steel cavity and the quartz casing, which is The double-helix water inlet and outlet method, the water inlet and the water outlet are set at the same end of the stainless steel cavity, this method prolongs the contact time between the overflowing water body and ultraviolet rays without increasing the length of the main structure, and can effectively improve the sterilization effect ; The end of the double helix water inlet and outlet quartz tube is provided with a water inlet and a water outlet; the water flow enters the double helix water inlet and outlet quartz tube from the water inlet at one end, and the ultraviolet rays emitted by the ultraviolet lamp tube pass through the quartz casing to treat the fungus in the water body. For killing, the water flow goes back and forth in the double-helix water inlet and outlet quartz tubes, and then flows out from the water outlet; fully contacting with ultraviolet rays, the bactericidal effect is greatly improved compared with the traditional over-flow ultraviolet germicidal lamps, ensuring that the water quality is safe, fresh, healthy.

Further, the water inlet and the water outlet are respectively connected to the water inlet pipeline and the water outlet pipeline through hoses, and the water inlet and the water outlet are respectively arranged on both sides of the end of the ultraviolet lamp tube.

Further, the other end of the double helix inlet and outlet water quartz tube is sealed.

As a preferred embodiment, the double-helix inlet and outlet water quartz tubes are arranged around the outside of the ultraviolet lamp tube.
