Description

Technical Field

[0001] The invention relates to the field of water treatment, in particular to a central micro-acid disinfected water treatment system. Background Art

[0002] At present, the dental filtered water supply system needs to be transmitted to the equipment at each medical station through a pipeline network. After a period of use, a certain degree of bacterial growth will inevitably occur in the pipeline, thus affecting the quality of the water. If the traditional method of adding disinfectants is used for sterilization, the equipment is large in size and high in cost. Moreover, disinfectants need to be added during use, which is very inconvenient to use. Summary of the invention

[0003] The object of the invention is to provide a centralized micro-acid disinfection water treatment system which has a simple structure, low manufacturing cost, is easy to use and can ensure the disinfection effect.

[0004] The central micro-acid disinfection water treatment system of the present invention is implemented as follows, including a reverse osmosis membrane water treatment mechanism, a pure water supply pipeline connected to the pure water supply port of the reverse osmosis membrane water treatment mechanism through a valve, and several terminal water supply ports with valves connected to the pure water supply pipeline. The special feature of the system is that an acidolysis production mechanism is provided, the acidolysis production mechanism is an electrolysis mechanism, the water inlet of the acidolysis production mechanism is connected to the pure water supply port of the reverse osmosis membrane water treatment mechanism, and the water outlet of the acidolysis production mechanism is connected to the water inlet of the pure water supply pipeline. Before using pure water every day, acid water containing chlorine (produced during electrolysis) is produced by the acidolysis production mechanism. Chlorine and acid produced), the pH value of acid water is 2-3, close the valve between the reverse osmosis membrane water treatment mechanism and the pure water supply pipeline, open the valve at the terminal water supply port, the acid water containing chlorine directly enters the pure water supply pipeline, and then is discharged from the terminal water supply port to disinfect the pure water supply pipeline. After disinfection, the acidolysis production mechanism continues to produce slightly acidic water, and the pH value of slightly acidic water is 5-6.5. Open the valve between the reverse osmosis membrane water treatment mechanism and the pure water supply pipeline to mix the slightly acidic water containing chlorine into the pure water, making the pure water become slightly acidic pure water, and then it is supplied to the terminal water supply ports of various places through the pure water supply pipeline.

[0005] When disinfection starts, the acid water containing chlorine produced by the acid hydrolysis production mechanism directly enters the pure water supply pipeline, which has high acidity and high chlorine content, and can effectively disinfect the pure water supply pipeline including the terminal water supply port with a valve; After disinfection, the process switches to producing slightly acidic water. The slightly acidic water containing chlorine is mixed into pure water to make the pure water slightly acidic pure water. Slightly acidic pure water can effectively inhibit the growth of bacteria, while ensuring that the pure water meets the hygiene requirements without affecting the requirements of pure water in medical dentistry.

[0006] Compared with the prior art, the present invention has the advantages of simple structure, low manufacturing cost, convenient use and guaranteed disinfection effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0009] The central micro-acid disinfection water treatment system of the present invention is now described in further detail with reference to the accompanying drawings and embodiments: Example 1: Figure 1 As shown, the central micro-acid disinfection water treatment system of the present invention is implemented as follows, including a reverse osmosis membrane water treatment mechanism 1, a pure water supply pipeline 3 connected to the pure water supply port of the reverse osmosis membrane water treatment mechanism 1 through a valve 2, and several terminal water supply ports with valves 4 connected to the pure water supply pipeline 3. The reverse osmosis membrane water treatment mechanism 1 includes a pre-stage filter 101, a constant pressure water pump 102, and a reverse osmosis membrane filter 103. The terminal water supply port matches the dental treatment station A. The special feature is that an acidolysis production mechanism 5 is provided. The acidolysis production mechanism 5 is an electrolysis mechanism. The water inlet of the acidolysis production mechanism 5 is connected to the pure water supply port of the reverse osmosis membrane water treatment mechanism 1, and the water outlet of the acidolysis production mechanism 5 is connected to the water inlet of the pure water supply pipeline 3. Before using pure water every day, Under the control of the control device B, acid water containing chlorine (chlorine and acid produced during electrolysis) is produced through the acidolysis production mechanism 5, and the pH value of the acid water is 2-3. The valve 2 between the reverse osmosis membrane water treatment mechanism 1 and the pure water supply pipeline 3 is closed, and the valve 4 at the terminal water supply port is opened. The acid water containing chlorine directly enters the pure water supply pipeline 3, and then is discharged from the terminal water supply port to disinfect the pure water supply pipeline 3. After the disinfection is completed, the acidolysis production mechanism 5 is converted to produce slightly acidic water containing chlorine, and the pH value of the slightly acidic water is 5-6.5. The valve 2 between the reverse osmosis membrane water treatment mechanism 1 and the pure water supply pipeline 3 is opened to mix the acid water containing chlorine into the pure water, so that the pure water becomes slightly acidic pure water, and then it is supplied to the terminal water supply ports of various places through the pure water supply pipeline 3.

[0010] Example 2: Figure 2As shown, a pure water storage tank 7 is provided, and a reverse osmosis membrane water treatment mechanism 1 is connected to the pure water storage tank 7 with a drain valve 6 through a valve 2, and a water inlet of a pure water supply pipe 3 is connected to the pure water storage tank 7 through a water pump 8, and a water return port of the pure water supply pipe 3 is connected to the pure water storage tank 7. After the pure water storage tank 7 supplies the terminal water supply port, the excess pure water flows back to the pure water storage tank 7. During disinfection, in addition to opening the valve 4 at the terminal water supply port, the drain valve 6 of the pure water storage tank 7 is opened at the same time. After the disinfection is completed, the valve 2 between the reverse osmosis membrane water treatment mechanism 1 and the pure water supply pipe 3 is opened, and the drain valve 6 is closed to mix the slightly acidic water containing chlorine into the pure water, so that the pure water becomes slightly acidic pure water, and then it is supplied to the terminal water supply ports at various locations through the pure water supply pipe 3.

[0011] When disinfection starts, the acid water with high acidity containing chlorine produced by the acid hydrolysis production mechanism 5 directly enters the pure water supply pipeline 3 and the pure water storage tank 7. The acid water has high acidity and high chlorine content, and can effectively disinfect the pure water supply pipeline 3 including the terminal water supply port with the valve 4; After disinfection, the slightly acidic water containing chlorine produced by the acidolysis production mechanism 5 is mixed into the pure water, making the pure water slightly acidic pure water. The slightly acidic pure water can effectively inhibit the growth of bacteria, while ensuring that the pure water meets the hygiene requirements without affecting the requirements of the pure water in medical dentistry.
