Description

Sterilizer

Technical field

The invention relates to a sterilizer.

Background technique

The water purification equipment has increased the water storage unit in order to solve the problem of insufficient water supply for the reverse osmosis and nanofiltration membrane process, but since the water storage unit and the long water pipeline are not completely sterile and safe, inevitably exist or More or less microbial breeding problems, so the water flowing out of the pure water storage bucket often has the problem of exceeding the microbiological index. In particular, the total number of bacteria in the water quality often exceeds the standard, so in order to achieve the goal of direct drinking, the water quality must be carried out. Sterilization and disinfection treatment is widely used because of its simple operation, reliable technology and small side effects. Therefore, in the drinking water purification or pure water system using the reverse osmosis or nanofiltration membrane water purification process, a UV sterilizer has been added, and the ultraviolet sterilizer has been widely used in the field of water treatment technology for killing bacteria and viruses in water. , micro-organisms and other harmful organisms. In household or commercial drinking water purification equipment, UV sterilization has become a reliable, efficient and safe water quality protection technology to kill bacteria, viruses and microbes that remain or breed in the water, and to ensure the sanitation and safety of water quality. The working principle of the ultraviolet sterilizer is that the water that needs to be sterilized flows through the water inlet, is irradiated and sterilized by the internally installed germicidal lamp, and then flows out through the water outlet after the bent pipe, thereby completing the sterilizing treatment of the water.

Ultraviolet germicidal lamps are low pressure mercury lamps. Low-pressure mercury lamps are excited by a lower mercury vapor pressure to emit ultraviolet light. UV disinfection and sterilization has a wide range of applications. Long-life UV germicidal lamps are of great significance in water disinfection and environmental protection projects. Water disinfection equipment such as pure water systems generally operate at 24 hours. The life and reliability of UV germicidal lamps are required. High, the existing sewage treatment device that uses ultraviolet rays to sterilize, because the direction of the water flow is uncontrollable, the sterilization effect is not uniform, and the problem of insufficient sterilization cannot be achieved.

The traditional ultraviolet sterilizer places the germicidal lamp inside the over-flow steel pipe, and is limited by the length of the flow-through component. The flow of the water in the sterilizer is very short, so the sterilization time of the germicidal lamp is short, which greatly affects the use efficiency of the germicidal lamp. The killing rate of the device against bacteria is not as good as expected.

detailed description

The drinking water channel structure of the sterilizer of the invention uses a quartz surrounding water pipe to pass the water, and the germicidal lamp is placed in the middle of the surrounding water pipe. The surrounding water pipe can be a spiral water pipe, a vertical labyrinth water pipe or a lateral labyrinth water pipe, so that the water flowing through the sterilizer of the present invention is subjected to 360 degree sterilization without a dead angle.

As shown in FIG. 1, the sterilizer includes a tube body 5, a germicidal lamp 11, a spiral water pipe 10, a water inlet fixing device 16, and a water outlet fixing device 1, and the water inlet fixing device and the water outlet fixing device are respectively fixed to the At both ends of the pipe body, one end of the spiral water pipe is connected to the water inlet fixing device, and the other end is connected to the water outlet fixing device.

The germicidal lamp is in the shape of a rod, and the germicidal lamp is located at the center of the spiral water pipe. The tube body is provided with a lamp fixing device 8 . One end of the germicidal lamp is fixed to the lamp fixing device 8 and the lamp tube is fixed. The device 8 is located in the middle of the spiral water pipe 10, and the other end is fixed to the water inlet fixing device.

The surrounding water pipe is made of quartz. The drinking water channel structure uses a quartz spiral water pipe to pass the water. The shape of the spiral tube is like a spring. The inside of the spring wire is a solid core, but the inside of the quartz spiral tube is hollow, the drinking water passes through the quartz spiral tube, and the germicidal lamp is placed in the spiral. In the middle, so that the drinking water has no contact with the germicidal lamp, the designed structure has the following advantages:

When the germicidal lamp is broken or damaged, the toxic substances in the germicidal lamp will not be polluted into the water, which ensures the safety of water.

The waterway is designed in a spiral shape. When the water rotates in the spiral tube, all the passing water will be turned over, which ensures that all the passing water will be uniformly irradiated by the ultraviolet rays, that is, all the passed water is sterilized, and at the same time the water It takes more than 1 second to pass through the spiral tube, thus ensuring that all the passing water will be irradiated with ultraviolet rays for sufficient time and thorough sterilization. This structure makes sterilization more thorough in terms of time and balance. Compared with the traditional structure, it is avoided that the water may be over-sterilized or has not passed until it has passed the sterilizer.
