Self-disinfecting device for large-scale stainless steel water dispenser and disinfection process thereof

Abstract

The invention relates to a self-disinfecting device for a large-scale stainless steel water dispenser and a disinfection process thereof. The self-disinfecting device comprises a heater and a heat exchanger between which a water pipe is arranged, and a water inlet pipeline is arranged at an opening A1 of the heat exchanger; a water outlet pipeline is arranged at an opening A4; taps are arranged on the water outlet pipeline; a circulating pipeline is connected between the water outlet pipeline and the water inlet pipeline so that a circulation loop is formed; and a circulating pump is arranged on the circulating pipeline. The self-disinfecting device is simple, achieves a good disinfection effect through high-temperature disinfection and is short in disinfection time; solenoid valves are adopted to control switching between circulatory disinfection and normal water supply, so that the switching is convenient; the operation is stable, the later-period operation and maintenance are convenient and the cost is low.

Description

technical field [0001] The invention relates to a water dispenser, in particular to a self-disinfection device for a large stainless steel water dispenser and a disinfection process thereof. Background technique [0002] At present, public water dispensers are provided in many densely populated public places. These public water dispensers are located in stations, hospitals and schools, and need to provide a large amount of warm water for instant drinking. Therefore, public water dispensers need to be equipped with cooling boiling water devices and corresponding water storage devices, but the temperature of warm water is suitable for the growth and reproduction of bacteria. Especially in spring and summer, the growth of bacteria will pollute the water quality, and even the excessive number of harmful bacteria will make drinking water People get sick. Therefore, the disinfection device in the public water dispenser is very important. The existing water dispenser disinfection ...

Problems solved by technology

Therefore, public water dispensers need to be equipped with cooling boiling water devices and corresponding water storage devices, but the temperature of warm water is suitable for the growth and reproduction of bacteria. Especially in spring and summer, the growth of bacteria will pollute the water quality, and even the excessive number of harmful bacteria will make drinking water personnel sick

Therefore, the disinfection device in the public water dispenser is very important. The existing water dispenser disinfection methods mainly include ozone sterilization, ultraviolet sterilization, filter sterilization, etc. Ozone sterilization is a bacteriolysis-level method, and the sterilization is thorough. It can damage a variety of items, and most of the devices inside the water dispenser are metals that are easily oxidized; the cost of ultraviolet sterilization is low, and the disinfection effect is less affected by water temperature and pH, but there is no continuous sterilization effect, and the sleeve of the ultraviolet lamp is easy to scale, which affects Bacteria will be revived due to ultraviolet light penetration and sterilizing effect; filtration sterilization can eliminate bacteria in time to avoid secondary pollution, but the filtration efficiency is low, it is difficult to discharge water with a large flow rate, and the filter medium also needs to be replaced regularly

The above external sterilization equipment is difficult to meet the needs of public water dispensers with high sterilization efficiency, remarkable sterilization effect, easy maintenance and low cost.
