Description

Technical Field

[0001] This utility model relates to the field of water supply system technology, specifically a pipeline disinfection water supply system. Background Technology

[0002] With the continuous development of society and the improvement of people's living standards, people are paying more and more attention to water safety. Most of the existing high-rise water supply systems use negative pressure water supply, box-type variable frequency water supply and simple booster pumps to pressurize water supply. After a long period of water supply, the inner walls of equipment pipelines, pipeline network riser main pipelines and branch pipelines on each floor will gradually be covered with impurities such as rust, mud, bacteria, and algae. In order to ensure the safety of users' water use, each pipeline needs to be disinfected and derusted.

[0003] The existing water supply equipment does not have the function of both supplying water and disinfecting and derusting the internal pipelines, high-rise riser main pipelines and branch pipelines on each floor. It requires manual cleaning and disinfection of branch pipelines and main pipelines on each floor, as well as disassembly and cleaning of equipment. This is labor-intensive, has low cleaning efficiency, and affects the normal water supply of the equipment. If the disinfection and cleaning of water supply equipment and pipelines are not properly managed and are not carried out within the required time, it will also lead to the growth of harmful substances, affect water quality, and thus lead to water safety issues for people. Summary of the Invention

[0004] In view of the above-mentioned technical deficiencies, this utility model provides a pipeline disinfection water supply system. This pipeline disinfection water supply system can not only disinfect the water supply equipment pipeline, but also automatically disinfect and remove rust from the main pipelines and branch pipelines of each building. Moreover, the system can automatically disinfect and remove rust during non-water use periods according to user settings, without affecting the normal water supply of the water supply equipment, and effectively ensuring water safety.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following specific solution:

[0006] This utility model provides a technical solution for a pipeline disinfection water supply system, which includes: a water storage tank, a water supply booster pump, a disinfection booster pump, a disinfectant tank, a pipeline mixer, and matching electric valves, check valves, rubber expansion joints, gate valves, and air vents in the pipeline.

[0007] The water inlet of the water storage tank is connected to the tap water inlet electric valve, and the water outlet of the water storage tank is connected to the water tank outlet electric valve. The other side of the water tank outlet electric valve is connected to the water supply booster pump inlet. The water supply booster pump outlet is connected to a check valve, a rubber expansion joint, and a water outlet gate valve to the user. An air vent valve is installed at the top of the terminal user's main pipeline, and a drain electric valve is connected between the check valve and the rubber expansion joint.

[0008] Based on the above-mentioned technology, the tap water pipeline is also connected to a disinfection booster pump. A disinfection inlet electric valve is installed before the inlet of the disinfection booster pump. The outlet of the disinfection booster pump is connected to the inlet of the pipeline mixer. The outlet of the pipeline mixer is connected to the pipeline between the water storage tank outlet electric valve and the water supply booster pump, and a disinfection main outlet electric valve is installed. The disinfectant connection port of the pipeline mixer is connected to the disinfectant tank. An electric valve for the disinfectant tank outlet and a disinfectant outlet gate valve are installed in the middle. The disinfectant tank is equipped with an electromagnetic metering pump, which can adjust the amount of disinfectant added according to the actual situation.

[0009] Based on the aforementioned technology, a control section is also included. All electrical components are electrically connected to the control box. These electrical components include, but are not limited to, electric valves, level gauges, remote pressure gauges, pressure transmitters, frequency converters, and displays. The control section of the controller can utilize existing technologies such as PLCs or microcontrollers. No restrictions or protections are imposed on the control methods, therefore, the control methods will not be described.

[0010] The working principle of this utility model is described as follows: During normal water supply, tap water enters the water storage tank through the inlet electric valve. When the user uses water, the outlet electric valve of the water tank opens, and all the electric valves of the disinfection section close. The equipment starts water supply normally, and the gas in the pipeline is discharged through the exhaust valve at the top of the main pipe, so that the pipeline is filled with water to meet the user's water needs.

[0011] The specific working principle of this utility model is described in two parts: During the disinfection and cleaning process, the drain electric valve is first opened to drain the water from the pipeline. Simultaneously, the water tank inlet and outlet electric valves are closed, while the disinfection inlet electric valve, disinfectant tank outlet electric valve, and main disinfection outlet electric valve are opened. After the water in the pipeline is drained, the drain electric valve automatically closes, and the disinfection booster pump, the electromagnetic metering pump in the disinfectant tank, and the water supply booster pump are started. The diluted disinfectant is pumped into the equipment pipeline, main pipeline, and branch pipelines after the water supply booster pump. Gas is discharged through the exhaust valve at the top of the main pipeline. After the diluted disinfectant fills all pipelines, all electromagnetic valves are closed. After a certain period of time, the drain electric valve opens to discharge the diluted disinfectant. Then, through the normal water supply process, all pipelines are filled with water for rinsing. Finally, the drain electric valve is opened to discharge the cleaning water, achieving the purpose of cleaning each pipeline.

[0012] The advantage of this utility model is that it can automatically disinfect and remove rust from the pipelines after the water supply pump, the main pipelines and the branch pipelines on each floor of the water supply equipment. This not only saves labor, but also allows for automatic disinfection and rust removal during non-water supply periods, without affecting the normal water supply of the equipment and ensuring water quality safety.

At the same time, the disinfection water inlet electric valve 13, the disinfectant water outlet electric valve 14 and the disinfection main water outlet electric valve 11 are opened, the disinfection booster pump 7 and the electromagnetic metering pump 18 are started, and other electric valves are closed. At this time, the diluted disinfectant mixture is injected into the pipeline for pipeline disinfection.

[0024] When the pipeline drain electric valve 16 is opened, the disinfectant mixture in the equipment pipeline and main pipeline is discharged. After there is no pressure in the pipeline, the drain electric valve 16 automatically closes. At the same time, the disinfection water inlet electric valve 13 and the disinfection main water outlet electric valve 11 are opened, the disinfection booster pump 7 is started, and other electric valves are closed. At this time, the water washing state is entered. After the water washing is completed, the drain electric valve 16 is opened to drain the water in the equipment pipeline and main pipeline. After the water is drained, the normal water supply state is resumed, and the drain electric valve is closed.
