Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and specifically discloses a dust removal system for water plants. Background Technology

[0002] To ensure tap water meets safety and hygiene requirements and prevent waterborne infectious diseases, disinfectants are added during the water purification process to inactivate pathogenic microorganisms in the water. Chlorine is widely used in the domestic water treatment industry due to its high cost-effectiveness. Residual chlorine refers to the amount of chlorine remaining in water after some has been consumed by bacteria, microorganisms, organic matter, and inorganic matter. If the residual chlorine in the water exceeds the normal range, it will cause serious harm to humans and the environment.

[0003] Reverse osmosis technology is commonly used in water production, purifying and filtering water through reverse osmosis membrane modules. However, residual chlorine in tap water can oxidize the reverse osmosis membrane, causing it to age and shorten its lifespan. Therefore, residual chlorine must be removed from the water before it enters the reverse osmosis membrane. This is achieved by adding a certain amount of sodium bisulfite solution to the water. Sodium bisulfite has reducing properties, protecting the reverse osmosis membrane from oxidation. Currently, water plants prepare their own sodium bisulfite solution, and the process involves manually pouring bagged sodium bisulfite into the solution tank through an opening at the top. The opening is then manually sealed with a water-sealed curtain. However, due to the small size of the opening on the existing solution tank, sodium bisulfite tends to accumulate at the opening during the pouring process, thus sealing the opening and preventing the sodium bisulfite powder from falling into the solution tank. Therefore, it is necessary to manually monitor the opening at all times and use hand tools to unclog it. However, during the pouring and unclogging process, sodium bisulfite powder is easily released into the air, resulting in material waste. In addition, the workers responsible for pouring and unclogging sodium bisulfite are prone to inhaling the sodium bisulfite that has fallen into the air, which can affect their health.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Refer to the instruction manual appendix Figure 1 As shown, a dust removal system for a water plant includes a solution tank 1, a jet pump 11, a dust collection tank 12, and a second pipe 8. The solution tank 1 has a solution tank opening 3, and a water seal curtain 5 that can be sealed to the solution tank 1 is provided at the upper end of the solution tank opening 3. A vacuum valve 6 is provided on the water seal curtain 5. The outlet end and the external water inlet end of the jet pump 11 are connected to the dust collection tank 12 and the solution tank 1 respectively through a first pipe 7. The dust collection tank 12 has a return pipe that communicates with the solution tank 1. One end of the second pipe 8 is connected to the upper end of the solution tank 1, and the other end of the second pipe 8 is connected to the water inlet end of the jet pump 11. A vacuum valve 6 is provided on the second pipe 8. With a vacuum gauge 9, sodium bisulfite powder can be poured into the solution tank opening 3 first, and the solution tank opening 3 can be sealed with a water seal curtain 5. Then, the jet pump 11 is started, and the second pipeline 8 evacuates the solution tank 1, causing the sodium bisulfite powder at the solution pipe opening 3 to fall into the solution tank 1. This technical solution avoids the waste of sodium bisulfite powder when it is poured into the solution tank, which would otherwise be scattered outside the solution tank. In addition, there is no need to manually unload the sodium bisulfite powder that has accumulated at the solution tank opening, which prevents the sodium bisulfite powder from affecting human health, saves time and effort, and can accelerate the mixing rate of sodium bisulfite powder with the water in the solution tank.

[0023] In a preferred embodiment of this invention, the second pipe 8 includes at least two branch pipes 10, which are connected to different heights of the solution tank 1. The branch pipes 10 can evacuate different heights inside the solution tank 1, thereby lifting the sodium bisulfite powder into the jet pump 11 to mix with external water and accelerating the mixing rate of sodium bisulfite powder and water.

[0024] In a preferred embodiment of this invention, the upper end of the solution tank opening 3 is provided with a funnel-shaped pouring port 2, the water seal curtain 5 is located at the upper end of the pouring port 2, and a plurality of nozzles 4 are distributed on the side of the pouring port 2. The nozzles 4 can rinse the pouring port 2 to prevent sodium bisulfite powder from accumulating on the side wall of the pouring port 2.

[0025] In a preferred embodiment of this invention, the first pipe 7 is connected to the bottom of the solution tank 1, ensuring that water is always available in the solution tank 1 as external water entering the jet pump 3 to mix with the sodium bisulfite powder.

[0026] Specifically, the bottom of the dust collection tank 12 is horizontally higher than the top of the solution tank 1. The two ends of the return pipe 17 are connected to the bottom of the dust collection tank 12 and the top of the solution tank 1, respectively, so that the dust collection tank 12 can return to the solution tank 1 by gravity.

[0027] As another preferred embodiment of this example, the first pipe 7 is provided with a first valve 13 and a second valve 14. The first valve 13 and the second valve 14 are located at the external water inlet and outlet of the jet pump 3, respectively. The water in the first pipe 7 can be evacuated by controlling the first and second valves.

[0028] Specifically, a third valve 15 is provided on the second pipeline 8.

[0029] In addition, a fourth valve 16 is provided on the return pipe 17, and the water in the dust collection water tank 12 is controlled to enter the solution tank 1 by opening and closing the fourth valve 16.

[0030] Working principle: The operator pours sodium bisulfite powder into the discharge port 2 at the top of the solution tank opening 3, closes the water seal curtain 5, which seals the solution tank 1, and starts the jet pump 3. The first pipe 7 draws water from the solution tank 1 into the jet pump 3, which in turn drives the second pipe 8 to create a vacuum in the solution tank 1. At this time, the sodium bisulfite powder accumulated at the solution tank opening 3 falls into the solution tank 1 due to the vacuum created by the second pipe 8. Then, the nozzle 4 starts to rinse the sodium bisulfite powder on the side wall of the discharge port 2. Some of the sodium bisulfite powder floats on the top of the liquid in the solution tank 1. The second pipe 8 then rinses the sodium bisulfite powder floating in the solution tank 1. The solution is not drawn into the jet pump 3 and mixed with the water in the first pipe 7 to form a sodium bisulfite solution, which then enters the dust collection tank 12. The sodium bisulfite solution in the dust collection tank 12 can be controlled by a valve to flow back into the solution tank 1. The entire dust removal system can determine whether the solution level is higher than that in the second pipe 8 by observing the changes in the vacuum gauge 9, and thus determine the liquid level in the solution tank 1. When the pointer of the vacuum gauge 9 fluctuates greatly, it indicates that liquid has entered the second pipe 8 and affected the detection data of the vacuum gauge 9, and the system is then shut down. In addition, the vacuum valve 6 can adjust the vacuum in the solution tank 1 as needed. When the pressure in the solution tank 1 is higher than the preset value of the vacuum valve 6, the vacuum valve 6 opens.

[0031] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0032] This technical solution provides a dust removal system for water treatment plants, including a solution tank, a jet pump, a dust collection tank, and a second pipeline. The solution tank has an opening, and a water seal curtain that can be sealed to the solution tank is installed at the upper end of the opening. A vacuum valve is installed on the water seal curtain. The outlet end and the external water inlet end of the jet pump are connected to the dust collection tank and the solution tank respectively through a first pipeline. The dust collection tank has a return pipeline that communicates with the solution tank. One end of the second pipeline is connected to the upper end of the solution tank, and the other end of the second pipeline is connected to the water inlet end of the jet pump. The connection involves a second pipe equipped with a vacuum gauge. Sodium bisulfite powder can be poured into the solution tank opening, the opening sealed with a water-sealed curtain, and the jet pump activated. The second pipe then evacuates the solution tank, causing the sodium bisulfite powder at the solution pipe opening to fall into the solution tank. This technical solution avoids the waste of sodium bisulfite powder that scatters outside the solution tank when it is poured in. Furthermore, it eliminates the need for manual removal of sodium bisulfite powder accumulating at the solution tank opening, preventing sodium bisulfite powder from affecting human health while saving time and effort.
