Description

Technical Field

[0001] The present application relates to the technical field of secondary water supply, and in particular to a residual chlorine replenishing system for a secondary water supply system. Background Art

[0002] The widespread use of secondary water supply facilities has effectively alleviated the contradiction between water supply and use in high-rise buildings and has become an important part of the urban water supply system.

[0003] In the related art, a Chinese patent with publication number CN221680879U discloses a safe chlorine replenishing device for a secondary water supply tank at the end of a pipe network. The device includes a water tank, a water inlet pipe, a water outlet pipe, a water inlet control valve, a chlorine replenishing unit and an inlet residual chlorine sensor. The water tank has a water inlet connected to the water inlet pipe and a water outlet connected to the water outlet pipe. The water inlet control valve is arranged between the water inlet pipe and the municipal water supply pipe. The inlet residual chlorine sensor is connected to the water inlet pipe for detecting the residual chlorine value of the municipal inlet water; the water inlet pipe is also provided with a chlorine replenishing port connected to the chlorine replenishing unit, which is used to replenish chlorine through the water inlet pipe when water enters the water tank; by setting up the chlorine replenishing unit, chlorine can be replenished in the water tank in time to improve the residual chlorine value of the water in the water tank, thereby meeting the water quality requirements of the water tank.

[0004] Regarding the above-mentioned related technologies, after chlorine is mixed with water in the water tank, if the water stays in the water tank for a long time, the residual chlorine will gradually be consumed. Since the water stays in the water tank for an uncertain time, when draining, the residual chlorine concentration at the water outlet of the water tank may decrease, and the water quality requirements further delivered to the user end will not meet the standards, further causing drinking water safety issues for users.

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The present application embodiment discloses a residual chlorine replenishing system for a secondary water supply system. Figure 1The residual chlorine replenishing system of the secondary water supply system includes a water tank 1 and a chlorination system 2. The water tank 1 is provided with a water inlet 11 and a water outlet 12. The chlorination system 2 is connected to the water inlet 11 of the water tank 1 through a first pipe 3, and the chlorination system 2 is connected to the water outlet 12 of the water tank 1 through a second pipe 4. A first valve 321311 is provided on the first pipe 3, and a second valve 421 is provided on the second pipe 4; a concentration detector 5 is connected to the side of the water tank 1 near the water outlet 12; according to the amount of water inlet, chlorine is added at the water inlet 11 through the first pipe 3 in a certain proportion, and chlorine is added to disinfect the water in the water tank 1. When the water is discharged, the residual chlorine content at the water outlet 12 is detected by the concentration detector 5. If the free residual chlorine at the water supply outlet 12 is insufficient, the second valve 421 is opened, and the chlorine in the chlorination system 2 is added to the water tank 1 through the second pipe 4 to make the chlorine content in the water reach the standard.

[0038] Reference Figure 1 In order to pass water into the water tank 1, the first pipe 3 includes a water inlet pipe 31 and a chlorine inlet pipe 32. The water inlet end of the water inlet pipe 31 is connected to the water outlet, and the chlorine inlet pipe 32 is connected between the water inlet pipe 31 and the chlorination system 2. The first valve 321 is provided on the chlorine inlet pipe 32; water flows into the water tank 1 through the water inlet pipe 31, and chlorine flows into the water tank 1 through the chlorine inlet pipe 32 and the water inlet pipe 31 in sequence, that is, chlorine can be introduced into the water tank 1 at the same time as water is taken in, thereby achieving the effect of increasing the residual chlorine value in the water tank 1.

[0039] Reference Figure 1 In order to discharge water to supply users, the second pipe 4 includes a water outlet pipe 41 and a chlorine replenishing pipe 42. The water outlet end of the water outlet pipe 41 is connected to the water outlet, and the chlorine replenishing pipe 42 is connected between the water outlet pipe 41 and the chlorination system 2. The second valve 421 is provided on the chlorine replenishing pipe 42; when the concentration detector 5 detects that the residual chlorine concentration near the water outlet 12 of the water tank 1 is low, the second valve 421 is opened to replenish chlorine for the water in the water tank 1; when the concentration detector 5 detects that the residual chlorine concentration near the water outlet 12 of the water tank 1 meets the standard, the second valve 421 is closed, and the water is discharged from the water outlet pipe 41.

[0040] Reference Figure 1 In order to control the water inlet and outlet, an inlet valve 311 is provided on the water inlet pipe 31, and a water outlet valve 411 is provided on the water outlet pipe 41. When water is inletting, the inlet valve 311 is opened. When water is out, if the concentration detector 5 detects that the residual chlorine concentration in the water tank 1 is low, the outlet valve 411 is closed and the second valve 421 is opened. When the residual chlorine content in the water tank 1 reaches the standard, the outlet valve 411 is opened and the second valve 421 is closed to allow water to be discharged from the outlet pipe 41.

[0041] Reference Figure 2In order to further make the water and chlorine in the water tank 1 react quickly, an agitator 13 is provided in the water tank 1 to achieve a uniform reaction between the water and the chlorine. In this embodiment, the agitator 13 is a conventional technology in this field, and the structure of the agitator 13 is not described in detail here.

[0042] Reference Figure 2 and Figure 3 When it is necessary to supplement chlorine to the water near the water outlet 12 in the water tank 1, in order to quickly mix the chlorine and water, a diverter plate 6 is fixedly connected to one end of the outlet pipe 41 near the water outlet 12. The diverter plate 6 is in the shape of a circular plate, and the outer diameter of the diverter plate 6 is larger than the water inlet pipe 41. The diverter plate 6 is located in the water tank 1, and one end face of the diverter plate 6 is a feed surface 61, and the other end face is a discharge surface 62. The diverter plate 6 is provided with a plurality of diverter holes 63 along the direction of water flow. The plurality of diverter holes 63 are distributed in multiple circles on the discharge surface 62, and the openings of the plurality of diverter holes 63 in each circle on the discharge surface 62 are evenly distributed along the circumference of the diverter plate, and each diverter hole 63 is connected to the water inlet pipe 31. After the chlorine enters the outlet pipe 41, it enters the water tank 1 through the plurality of diverter holes 63 to achieve uniform mixing of chlorine and water.

[0043] Reference Figure 3 and Figure 4 When water is discharged, in order to ensure that the water flow can be discharged from the water outlet pipe 41 at a certain flow rate, a water outlet groove 64 is opened through the diverter plate 6 along the water flow direction. The water outlet groove 64 is set corresponding to the water outlet pipe 41, and the aperture of the water outlet groove 64 is larger than the aperture of the diverter hole 63. By setting the water outlet groove 64, when draining water, the water flows from the water outlet groove 64 into the water outlet pipe 41 for further discharge.

[0044] Reference Figure 4 In order to allow chlorine to smoothly enter the diversion hole 63 and be discharged from the diversion hole 63, the water outlet 64 has a first water outlet portion 641 and a second water outlet portion 642. The first water outlet portion 641 is located on the side of the second water outlet portion 642 away from the water outlet pipe 41, and the inner diameter of the first water outlet portion 641 is smaller than the inner diameter of the second water outlet portion 642, so that a blocking portion 643 is formed at the connection between the first water outlet portion 641 and the second water outlet portion 642. A plurality of connecting grooves 6421 are opened on the side wall of the second water outlet portion 642, each connecting groove 6421 is connected to the second water outlet portion 642. The groove 6421 is connected to a diverter hole 63, so that after the chlorine enters the water inlet pipe 31, it enters the second water outlet 642 and the connecting groove 6421 in sequence and is discharged from the diverter hole 63. Since a blocking portion 643 is formed between the first water outlet 641 and the second water outlet 642, after entering the second water outlet 642, the chlorine will not immediately enter the first water outlet 641 and enter the water tank 1 from the first water outlet 641, but will enter the diverter hole 63 through the connecting groove 6421 on the second water outlet 642.

[0045] Reference Figure 4In order to further improve the uniformity of the reaction between chlorine and water, the connecting groove 6421 is arranged at an angle. The connecting groove 6421 is arranged at an angle along the direction from the feed surface 61 to the discharge surface 62 toward the side away from the central axis of the water outlet pipe 41, that is, the multiple connecting grooves are in a diffuse state relative to the central axis of the water outlet pipe 41. The connecting groove 6421 guides the chlorine so that the chlorine entering the connecting groove 6421 can enter the water tank 1 in a diffused form, so that the chlorine and water can be diffused more evenly, the efficiency is improved, and the content meets the standard.

[0046] The implementation principle of the residual chlorine replenishing system of a secondary water supply system in the embodiment of the present application is as follows: water enters the water tank 1 through the water inlet pipe 31, the first valve 321 is opened, and chlorine enters the water inlet pipe 31 through the chlorine inlet pipe 32 and enters the water tank 1 together with the water, thereby meeting the water quality requirements in the water tank 1. When the concentration detector 5 detects that the residual chlorine concentration at the water outlet 12 of the water tank 1 is low, the second valve 421 is opened and the water outlet valve 41 is closed. The chlorination system 2 passes chlorine into the water tank 1 through the chlorine replenishing pipe 42 and the water outlet pipe 41. After the chlorine enters the water outlet trough 64, it enters the water tank 1 through the connecting groove 6421 and the diversion hole 63 in turn. The chlorine is guided by the inclined direction of the connecting groove 6421 to achieve uniform diffusion of chlorine and water, ensuring uniform residual chlorine in the water tank 1. When the concentration detector 5 detects that the residual chlorine concentration at the outlet of the water tank 1 meets the standard, the second valve 421 is closed and the water outlet valve 411 is opened to allow water to enter the water outlet pipe 41 from the water outlet trough 64 and then be discharged.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
