Description

New Disinfection Device Combining Ultraviolet and Sodium Hypochlorite

technical field

The utility model belongs to the technical field of drinking water disinfection devices, and in particular relates to a new type of disinfection device combined with ultraviolet rays and sodium hypochlorite.

Background technique

The current situation of microbial risks in drinking water in villages and towns in my country is common. The application and implementation of disinfection technology has become an important issue for the health of rural drinking water. However, most rural water supply projects do not choose appropriate disinfection technology and equipment according to their own characteristics, but only consider Due to economic factors, choosing a cheaper disinfection method, or only going through a simple filtration and precipitation process without using a disinfection process, will pose a great threat to the health of the people. At the same time, there are still many problems in the drinking water supply of villages and towns in my country, scattered water supply points, relatively small scale, and limited village and town management level. Disinfection technology to meet the disinfection needs of drinking water.

The current disinfection techniques can be roughly divided into two categories, namely, physical methods and chemical methods. Chemical disinfection methods generally include chlorine disinfection, chlorine dioxide disinfection, ozone disinfection, sodium hypochlorite disinfection, etc. Among them, although the cost of chlorine disinfection is relatively low, it may make China Produce trihalomethanes (TMHs) substances, and trihalomethanes (TMHs) substances are very carcinogenic to humans. Drinking water after chlorine dioxide disinfection has a special smell, and it will also produce some substances that are recognized by the United Nations Health Organization Suspected carcinogens, ozone disinfection has high cost, poor stability, and limited application range in remote rural areas. In contrast, sodium hypochlorite disinfection is the most stable chemical disinfection method and is most suitable for disinfection of drinking water in villages and towns However, the current sodium hypochlorite disinfection also has problems such as low degree of automation and outdated technology; in physical disinfection, ultraviolet disinfection is the most commonly used disinfection method, because ultraviolet disinfection is the only disinfection method that does not produce disinfection by-products. Broad-spectrum bactericidal ability will not cause secondary pollution, but it lacks continuous bactericidal ability, and the sterilized bacteria are prone to photoreactivation. At the same time, according to experimental research, the distribution of light intensity in the ultraviolet disinfection reactor is uneven, and the light intensity at the entrance and exit is weak, which decreases with the increase of the distance between the water flow and the lamp tube; the light intensity at the front part of the reactor and the inner wall of the reactor is small The high flow rate is the reason that affects the disinfection efficiency.

In the present utility model, the ultraviolet sterilizer 5 is connected to the console 6 for control, and the console 6 is installed on the ground 13 or the wall according to actual needs.

In the present utility model, there are 10-15 holes of the same size on the surface of the rectifying plate 16, which are evenly distributed on the surface of the rectifying plate 16, and the distance between each hole is 1-2cm.

In the utility model, the cross section of the plane mirror 17 is a regular hexagon. 

In the utility model, the ultraviolet sterilizer 5 includes a reflective device with a regular hexagonal cross-section. In order to ensure a good reflective effect, the device adopts a plane mirror made of glass, and the plane mirror is connected with the outer sleeve of the ultraviolet sterilizer 5 .

The beneficial effect of the utility model is that, due to the use of ultraviolet disinfection and sodium hypochlorite disinfection combined disinfection equipment, sodium hypochlorite is added at the end of ultraviolet disinfection, which solves the weakness of ultraviolet disinfection without continuous disinfection ability. The consumption of sodium hypochlorite is reduced, which is more than 80% less than that of completely using sodium hypochlorite for disinfection, and there is no need to set up another disinfection pool. Since the ultraviolet sterilizer adopts rectification facilities and plane mirror reflection, it overcomes the decline in the disinfection ability of ultraviolet disinfection due to too fast flow rate and too far away from the lamp tube, and strengthens the ability of ultraviolet disinfection, and the disinfection effect is increased by 20% compared with the original. At the same time The power consumption is reduced, and one set of equipment can be disassembled for maintenance in case of failure, and the other set of equipment can be operated independently to ensure stable water disinfection effect.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Embodiment 1: As shown in Figures 1-3, the device is composed of a main water delivery pipeline 1, a sodium hypochlorite storage tank 2, an ultraviolet sterilizer 5, a console 6, a base 13 and a sodium hypochlorite metering pump 14. The main water pipeline 4 includes a water inlet 1, a first valve 7, and a water outlet 3. The end close to the water inlet is connected to the ultraviolet sterilizer 5 through a second valve 11 through a first flange 8, and its flow is controlled by a second valve 11. ; The main water pipeline 4 is connected to the ultraviolet sterilizer 5 through the second flange 9 near the water outlet, and the flow is controlled by the third valve 12 . The sodium hypochlorite storage tank 2 is located behind the ultraviolet sterilizer 5 and the main water pipeline 1 interface. The operating parameters of the ultraviolet sterilizer 5 can be controlled through the console 6, and the console 6 is installed on the ground or on the wall according to actual needs. The inside of the ultraviolet sterilizer 5 includes a rectifying plate 16 , a flat mirror 17 , an ultraviolet lamp 14 , and a quartz tube cover 15 . There are 10-15 holes of the same size on the surface of the rectifying plate 18, which are evenly distributed on the surface of the ultraviolet sterilizer 5, and the distance between each hole is 1-2cm. The cross section of the plane mirror 17 is a regular hexagon.

The drinking water enters the main water delivery pipeline 4 through the water inlet 1 after passing through the front-end coagulation, filtration, precipitation and other processes. At this time, the first valve 7 is closed, the second valve 11 and the third valve 12 are opened, and the drinking water enters the ultraviolet sterilizer 5. After being rectified by the rectifying plate 18, the flow rate is relatively uniform and no eddy current is formed, which strengthens the ultraviolet disinfection effect. Since the ultraviolet rays are reflected by the plane mirror 17, the water entering the edge of the ultraviolet sterilizer is also fully disinfected. After disinfection treatment The influent water returns to the main water pipeline 4. According to the ultraviolet disinfection effect, the sodium hypochlorite in the sodium hypochlorite storage tank 2 is added to the main water pipeline 4 through the metering pump 14 to further disinfect the drinking water to ensure the amount of residual chlorine in the water and prevent bacteria. The light is resurrected.

Embodiment 2: If the ultraviolet disinfection equipment breaks down and needs to be removed for maintenance, the second valve 11 and the third valve 12 can be automatically controlled or manually closed through the console 6, and after the first valve 7 is opened, pass through the first flange 8. The second flange 9 removes the ultraviolet disinfection system for maintenance, so that the incoming water can be directly disinfected by sodium hypochlorite to ensure that the drinking water is disinfected. If the sodium hypochlorite disinfection system fails, use the opposite method to run ultraviolet disinfection alone to ensure the disinfection effect.
