Technical Field
[0001] The utility model relates to the technical field of water supply for protective engineering, in particular to a disinfection water supply system for domestic water for protective engineering. Background Art
[0002] The water source for urban domestic water is treated and disinfected in the water treatment facilities of the water plant until the water quality reaches the standard for domestic drinking water. The water is then transported to the municipal water supply network through the water pump station, thereby supplying residential areas, factories, and other places with water for living, production, and fire fighting.
[0003] The domestic water for protective projects is used in an isolated protection state. When the external water source is completely cut off and the protective project enters a high-level combat readiness state, it must still be able to ensure the continuous work and life of personnel of a corresponding scale for 15 days or even longer. The current defects of the domestic water system for protective projects are: 1) Since the water source is directly supplied by the municipality, the municipal tap water is polluted to varying degrees during the transportation process, and the water quality is reduced, resulting in the water quality failing to meet the standards for drinking water. 2) In order to prevent water pollution, it is stipulated that the water storage design renewal cycle of the domestic water pool (tank) should not exceed 48 hours, which is far from the requirements of the isolation protection time of the protective project (15 days or even longer). If the water does not flow for a long time, there is a hidden danger of stagnant water.
[0004] Therefore, in view of the above-mentioned defects, a corresponding water source disinfection and water supply system is proposed for the domestic water supply in the protection project to ensure the survival needs of personnel during the isolation and protection period. Utility Model Content
[0005] In view of the shortcomings of the above-mentioned prior art, the present application provides a disinfection water supply system for domestic water for protective projects. By regularly running the circulation pump, the guide plate and the vortex prevention device can intermittently circulate and guide the water in the pool to avoid retention and significantly improve the activity of the water. On the other hand, the residual chlorine detection device constantly detects the concentration of disinfectant in the pool and adds medicine according to the concentration, thereby performing a secondary disinfection on the water quality.
[0006] The technical solution adopted by the utility model to solve the above technical problems is as follows:
[0007] A disinfection water supply system for domestic water used in a protective project comprises at least one domestic water pool, a water supply network is formed from the domestic water pool to various water use points in the protective project through a variable frequency water supply system, and a circulating dosing system is also arranged in the domestic water pool to detect the residual chlorine content in the domestic water pool and perform circulating dosing.
[0008] Furthermore, the variable frequency water supply system includes a variable frequency water supply unit arranged in a domestic water pool, and a plurality of water supply main pipes evenly distributed in the protection project are led out from the pump of the variable frequency water supply unit.
[0009] Furthermore, it also includes an ultraviolet disinfector arranged along the water supply path of the water supply main pipe.
[0010] Furthermore, the circulating dosing system includes a residual chlorine detection device arranged in the domestic water pool and a circulating pump arranged outside the domestic water pool, one end of the circulating pump is connected to the domestic water pool through a vortex prevention device, and the other end of the circulating pump is connected to the domestic water pool through a circulating return pipe. It also includes a disinfectant storage container arranged outside the domestic water pool, and a metering pump is provided at the outlet of the disinfectant storage container, and the pump back of the metering pump is connected to the circulating return pipe through a dosing pipe.

[0012] Furthermore, the domestic water pool is arranged in a tunnel of the protection project, and the inner wall of the domestic water pool is lined with a stainless steel plate.
[0013] Furthermore, a plurality of guide plates are arranged in the domestic water pool, and the guide plates are arranged along an S-shaped guide path.
[0014] The beneficial effects of the utility model are as follows:
[0015] Compared with the existing technology, the traditional domestic water pool has a long renewal cycle, and the water is stagnant in the pool without flowing, which poses a hidden danger of dead water. The utility model regularly runs the circulation pump to prevent the water from becoming stagnant dead water due to staying in the pool for too long. It cooperates with the stainless steel guide plate to improve the flow state of the circulating water in the horizontal direction, reduce the impact of short-flow, and form an ideal plug flow state. After the circulating return water pipe enters the pool, a vortex prevention device is installed in the vertical direction against the inner wall of the pool, so that the circulating water can also have an ideal plug flow state in the vertical direction, thereby significantly improving the activity of the water in the pool.

[0021] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.
[0022] The utility model provides a disinfection water supply system for domestic water of a protection project, aiming to solve the problem that the water quality of the water source in the traditional protection project deteriorates due to the municipal secondary transportation and to avoid the hidden danger that the water in the protection project may become dead water due to too long retention time.
[0023] like Figures 1 to 3 As shown, the utility model includes a domestic water pool 1, and a water supply network is formed from the domestic water pool 1 to various water use points in the protection project through a variable frequency water supply system. A circulating dosing system is also arranged in the domestic water pool 1 to detect the residual chlorine content in the domestic water pool 1 and perform circulating dosing.
[0024] Through the above technical solution, the water in the pool is pressurized by the variable frequency water supply unit, assisted by ultraviolet disinfection, and then led out of the domestic water supply main pipe 2 from the pump, and arranged into a branch-like pipe network in the protection project to provide domestic water for each water point. Through the circulating dosing system, the circulating pump 4 runs regularly to ensure the activity of the water in the pool, and the residual chlorine detection device 3 always detects the concentration of the disinfectant in the pool, and the circulating pump 4 and the metering pump 8 are linked to start according to the detected concentration to achieve follow-up dosing.
[0025] In some embodiments, the variable frequency water supply system includes a variable frequency water supply unit (illustrated in the figure) arranged in a domestic water pool 1, and a plurality of water supply main pipes 2 evenly distributed in the protective project are led out from the pump of the variable frequency water supply unit.
[0026] In some embodiments, it also includes an ultraviolet disinfector arranged along the water supply path of the water supply main pipe 2. In this embodiment, the ultraviolet disinfector includes but is limited to various conventional models in the field of water treatment.

[0028] Through the above technical solution, the circulation pump 4 is operated regularly, so as to avoid the water becoming stagnant water due to staying in the pool for too long, which is in line with the provisions of the specification that the water storage design renewal cycle of the domestic water pool 1 (tank) should not exceed 48h;
[0029] The domestic water pool 1 is disinfected twice with chlorine disinfectant. The residual chlorine detection device 3 constantly detects the concentration of disinfectant in the pool. The circulation pump 4 is automatically turned on when the effective chlorine amount is less than 0.05 mg / L, and is automatically turned off when the effective chlorine amount is ≥ 0.07 mg / L. The dosing pipe 9 is connected to the circulating return pipe 5, and is evenly added into the pool along with the vortex prevention device 6.
[0030] In some embodiments, the metering pump 8 and the circulation pump 4 are both connected to the residual chlorine detection device 3 by signal.
[0031] In some embodiments, the living water pool 1 is arranged in the tunnel of the protection project, and the inner wall of the living water pool 1 is lined with stainless steel plates. Since the protection project has a long isolation protection time and stores a large amount of living water, in order to save building area, the living water pool 1 is built using the tunnel structure as the pool wall, and is lined with stainless steel plates to ensure that the materials in contact with water are safe and appropriate, thereby preventing water pollution.
[0032] In some embodiments, a plurality of guide plates 7 are provided in the living water pool 1 , and the guide plates 7 are arranged along an S-shaped guide path.

After the circulating return pipe 5 enters the pool, a swirl prevention device 6 is made in the vertical direction against the inner wall of the pool, so that the circulating water can also have an ideal push flow state in the vertical direction. The number of swirl prevention devices 6 can be appropriately set according to the depth of the living water pool 1.
[0034] The working principle of this utility model:
[0035] By running the circulation pump 4 regularly, the water can be prevented from becoming stagnant water due to staying in the pool for too long, which is in line with the specification that the water storage design renewal cycle of the domestic water pool 1 (tank) should not exceed 48 hours; at the same time, a stainless steel guide plate 7 is made in the pool to improve the flow state of the circulating water in the horizontal direction, reduce the impact of short-flow, and form an ideal plug flow state. After the circulating return pipe 5 enters the pool, a swirl prevention device 6 is made in the vertical direction against the inner wall of the pool, so that the circulating water can also have an ideal plug flow state in the vertical direction. The number of swirl prevention devices 6 can be appropriately set according to the depth of the domestic water pool 1.
[0036] The domestic water pool 1 is disinfected twice with chlorine disinfectant. The residual chlorine detection device 3 constantly detects the concentration of disinfectant in the pool.

The dosing pipe 9 is connected to the circulating return pipe 5, and is evenly added into the pool along with the vortex prevention device 6.
[0037] The water in the pool is pressurized by the variable frequency water supply unit and disinfected with ultraviolet light. It is then led out of the domestic water supply main pipe 2 from the pump and arranged into a branch-like pipe network within the protection project to provide domestic water for each water point.
[0038] The timing cycle system includes the following working states:
[0039] a. Routine control: After the protection project is officially put into use, the living water pool 1 always contains 15 days' living water (about 530m3) for people of corresponding size. The daily water consumption is controlled by the float valve of the water tank and replenished to the full water level in time. The circulation pump 4 is manually turned on every 2 days (48h) for 5h to ensure the uniformity and fluidity of the water in the pool and maintain the activity of the water.
[0040] b. Wartime control: During wartime, the external water source is cut off, and the water in the pool is gradually consumed and reduced as the isolation protection time increases. The operation cycle of the circulation pump 4 is still guaranteed to be once every 2 days, and the operation time is adjusted according to the water volume, and it is implemented according to the principle of circulating all the water once.
[0041] The circulating dosing system includes the following two working states:
[0042] a. Automatic control: When the residual chlorine detection device 3 detects that the effective chlorine content is less than 0.05 mg / L, the circulation pump 4 is automatically turned on, and the metering pump 8 is also turned on to add medicine; when the effective chlorine content is ≥0.07 mg / L, the metering pump 8 is automatically stopped and the circulation pump 4 is turned off at the same time.
[0043] b. Manual control: manual control buttons for the circulation pump 4 and the metering pump 8 are provided on the panel of the control cabinet, and the manual control button of the metering pump 8 is linked with the circulation pump 4, that is, when the metering pump 8 is manually turned on, the pump starting sequence is: first turn on the circulation pump 4 and then turn on the metering pump 8, and the action is reversed when turned off; when the circulation pump 4 is manually turned on, only the circulation pump 4 is turned on.
