Description

water supply system

technical field

The invention relates to the field of water supply, in particular to a water supply system.

Background technique

In order to provide residents with safer drinking water, some communities or residential buildings have separate secondary water supply systems to supply water to residents. For example, the pure water of the large-scale RO engineering mechanism in the community is supplied to users through the secondary water supply system. In the secondary water supply process, such as the pure water produced by the RO engineering mechanism, although some toxic and harmful chemical substances are removed, the residual chlorine that can be used for disinfection and sterilization in the pipeline is also removed. This will inevitably lead to the problem of secondary pollution caused by the growth of bacteria in the pipeline. The current secondary water supply system generally uses separate chlorine addition, ozone addition, or ultraviolet sterilization to eliminate bacteria. Adding chlorine alone will introduce chemical substances twice, adding ozone will produce ozone water that will affect the taste of water, and ozone water has a longer half-life, and ultraviolet sterilization has a better instantaneous effect, but the pipeline at the back end of ultraviolet cannot Sterilization treatment.

Patent No. 201410400943.3 discloses an air-energy water heater with a bactericidal effect. An ozone generator is connected to the first water tank and the second water tank to provide ozone for the water in the water tank.

But the obtained ozone-containing water of this patent cannot guarantee that the ozone has been completely decomposed when it is supplied to the user. Ozone has strong oxidizing properties and may cause certain damage to the skin. If this technology is used in the treatment of drinking water, it may also affect the taste.

The fourth liquid level detection device 16.

The working principle of the water supply system of the present invention will be described in conjunction with FIG. 1 .

First, when the system is just established: after the pipes and water tanks are cleaned, fill the first water tank 11 with water. While injecting water, the ozone generator 10 simultaneously prepares ozone, which is mixed with water to form ozone water. After the first water tank 11 is full of water, it is reserved for a certain period of time to make the ozone decay to a safe value range. Then open the first water discharge control valve 3 and the first water intake control valve 5, the first water tank 11 supplies water to the user, and the water supply circulation pipeline sequence is the first water tank 11—the first water discharge control valve 3—the water pump 30— Ultraviolet sterilization device 20—user water supply building—one-way valve 7—first water inlet control valve 5—first water tank 11.

Second, the normal water supply process: during the water supply process of the first water tank 11, the first water supply control valve 1, the second drainage control valve 4 and the second water intake control valve 6 are closed. The second replenishment control valve 2, the first drainage control valve 3, and the first water intake control valve 5 are in an open state. During the water supply process of the first water tank 11, inject water and ozone into the second water tank 12, and carry out ozone sterilization after mixing. The process of water supply from the first water tank 11 can provide enough time for the second water tank 12 to carry out ozone sterilization and ozone decomposition.

Third, the pipeline disinfection process: when the pipeline needs to be disinfected, the first water tank 11 still supplies water normally, and the second water tank 12 passes ozone to make ozone water. When the concentration of ozone water in the second water tank 12 reaches the set value that can be used for sterilization, the first replenishment control valve 1, the second replenishment control valve 2, the first drainage control valve 3 and the first water intake control valve 5 perform closure. The second drainage control valve 4 and the second water intake control valve 6 are opened, and the ozone water in the second water tank 12 is pumped into the pipeline system. When the whole pipeline was full of ozone water, close the second drainage control valve 4 and the second water inlet control valve 6, and keep it for several minutes for disinfection. In this step, the second drain control valve 4 and the second water intake control valve 6 may not be closed to keep the water circulation for several minutes. After the disinfection process is finished, the second drainage control valve 4 is closed, the first drainage control valve 3 and the second water intake control valve 6 are opened, and the ozone-free water is pumped into the pipeline from the first water tank 11, and the pipeline contains The ozone water squeezes into the second water tank 12. When the water containing ozone in the pipeline is all squeezed into the second water tank 12. Close the second water inlet control valve 6, and open the first water inlet control valve 5. Restoration of the first water tank 11—the first drainage control valve 3—water pump 30—ultraviolet sterilizing device 20—user water supply building—one-way valve 7—the first water inlet control valve 5—the first water tank 11 circulation water supply lines. The second water tank 12 then performs the step of ozone decomposition. After the first water tank 11 is supplied with water, the ozone in the second water tank 12 is also basically decomposed, and then the second water tank 12 is switched to supply water, and the first water tank 11 performs water replenishment and ozone sterilization.

From the above description, it can be seen that the above-mentioned embodiments of the present invention have achieved the following technical effects:

Water supply system of the present invention has realized following effect:

1. Two water tanks are used to perform ozone disinfection and water supply operations in turn, so that one water tank is supplying water while the other water tank is simultaneously performing ozone disinfection and ozone decomposition operations. Therefore, it will not cause the user to get the ozone water, and there is no need to wait for the time for the ozone to decompose.

2. When the pipeline is sterilized, one water tank is used for water supply, and the other water tank is used for the preparation of ozone water. After the preparation of the ozone water is completed, the pipeline is switched, and the ozone water is pumped into the pipeline to disinfect the pipeline. Since the ozone water disinfection time only takes a few minutes, the ozone water only needs to stay in the pipeline for a few minutes before switching the pipeline, replacing the ozone water in the pipeline with ozone-free water, and then restoring the water supply to users. The process of pipeline disinfection only needs a few minutes of contact with ozone water disinfection, and there is no need to wait for the time of ozone decomposition.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
