Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, and specifically discloses a dust removal system for a water plant. Background Art

[0002] To ensure that tap water meets the safety and hygiene requirements and prevent waterborne infectious diseases, disinfectants need to be added during the purification process of tap water to inactivate pathogenic microorganisms in the water. Residual chlorine refers to the amount of chlorine remaining after chlorine is added to water. After part of the chlorine is consumed by reacting with bacteria, microorganisms, organic matter, and inorganic matter in the water, the remaining amount of chlorine is called residual chlorine. If the residual chlorine in the water exceeds the normal range of residual chlorine, it will cause serious harm to humans and the environment.

[0003] During the process of water production, a reverse osmosis water production technology is often used to purify and filter water through a reverse osmosis membrane module. However, the residual chlorine contained in tap water will oxidize the reverse osmosis membrane, causing the reverse osmosis membrane to age and shortening the membrane life. Therefore, before water enters the reverse osmosis membrane, we need to remove the residual chlorine in the water. Therefore, a certain amount of sodium bisulfite solution needs to be added to the storage water. Sodium bisulfite has a certain reducing property to protect the reverse osmosis membrane from oxidation. The water treatment plant prepares the sodium bisulfite solution by itself. In the existing process of preparing sodium bisulfite, workers need to pour the bagged sodium bisulfite into the opening at the upper end of the solution tank, and then manually seal the opening with a water seal curtain. However, due to the small opening on the existing solution tank, when pouring sodium bisulfite, sodium bisulfite is prone to accumulate at the opening, and then seal the opening, resulting in sodium bisulfite powder being unable to fall into the solution tank. Therefore, workers need to constantly monitor the opening and use tools to dredge the opening. However, during the process of pouring and dredging sodium bisulfite powder, it is easy to float into the air, causing material waste. In addition, the workers responsible for pouring and dredging sodium bisulfite are prone to inhaling the sodium bisulfite floating in the air, which affects their physical health.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0022] Refer to the attached specification Figure 1As shown in the figure, a dust removal system for a waterworks includes a solution tank 1, a jet pump 11, a dust collection water tank 12, and a second pipeline 8. A solution tank opening 3 is provided on the solution tank 1. A water seal curtain 5 that can seal 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 respectively connected to the dust collection water tank 12 and the solution tank 1 through a first pipeline 7. The dust collection water tank 12 is provided with a return pipeline communicating with the solution tank 1. One end of the second pipeline 8 communicates with the upper end of the solution tank 1, and the other end of the second pipeline 8 is connected to the water inlet end of the jet pump 11. A vacuum gauge 9 is provided on the second pipeline 8. Sodium bisulfite powder can be first poured into the solution tank opening 3, and the solution tank opening 3 is sealed with the water seal curtain 5. 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 floating outside the solution tank when pouring it; in addition, there is no need for manual feeding of the sodium bisulfite powder accumulated at the solution tank opening, which saves time and effort while preventing sodium bisulfite powder from affecting human health. Moreover, it can accelerate the mixing rate of sodium bisulfite powder and the water body in the solution tank.

[0023] As a preferred implementation manner of this embodiment, the second pipeline 8 includes at least two sub-pipelines 10, and the sub-pipelines 10 communicate with different heights of the solution tank 1. The sub-pipelines 10 can evacuate different heights inside the solution tank 1, improve the entry of sodium bisulfite powder into the jet pump 11 for mixing with external water, and accelerate the mixing rate of sodium bisulfite powder and the water body.

[0024] As a preferred implementation manner of this embodiment, a "funnel-shaped" pouring port 2 is provided at the upper end of the solution tank opening 3. The water seal curtain 5 is located at the upper end of the pouring port 2, and several spray heads 4 are distributed on the side surface of the pouring port 2. The spray heads 4 can wash the pouring port 2 to avoid sodium bisulfite powder accumulating on the side wall of the pouring port 2.

[0025] As a preferred implementation manner of this embodiment, the first pipeline 7 communicates with the bottom of the solution tank 1 to ensure that there is always water in the solution tank 1 as external water entering the jet pump 3 for mixing with sodium bisulfite powder.

[0026] Specifically, the horizontal position of the bottom of the dust collection water tank 12 is higher than the horizontal position of the top of the solution tank 1. Both ends of the return pipeline 17 are respectively connected to the bottom of the dust collection water tank 12 and the top of the solution tank 1, and the dust collection water tank 12 can flow back into the solution tank 1 by gravity.

[0027] As another preferred embodiment of this embodiment, a first valve 13 and a second valve 14 are provided on the first pipeline 7. The first valve 13 and the second valve 14 are located at the external water inlet end and the water outlet end of the jet pump 3, and the water body in the first pipeline 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 reflux pipeline 17, and the water body in the dust collection water tank 12 is controlled to enter the solution tank 1 by switching the fourth valve 16.

[0030] Working principle: The staff pours sodium bisulfite powder into the feeding port 2 at the upper end of the opening of the solution tank 3, closes the water seal curtain 5, and the water seal curtain 5 seals the solution tank 1. The jet pump 3 is started, and the first pipeline 7 takes the water body in the solution tank 1 as external water and enters the jet pump 3, thereby driving the second pipeline 8 to evacuate the solution tank 1. At this time, the sodium bisulfite powder accumulated at the opening 3 of the solution tank falls into the solution tank 1 due to the air extraction of the second pipeline 8. At this time, the nozzle 4 is started to wash the sodium bisulfite powder on the side wall of the feeding port 2. Part of the sodium bisulfite powder floats on the upper end of the liquid in the solution tank 1. The second pipeline 8 extracts the sodium bisulfite powder floating in the solution tank 1 to the jet pump 3 end and mixes it with the water body in the first pipeline 7 to form a sodium bisulfite solution and enters the dust collection water tank 12. The sodium bisulfite solution in the dust collection water tank 12 can be controlled by a valve to flow back into the solution tank 1. The entire dust removal system can judge whether the solution is higher than the second pipeline 8 by observing the change of the vacuum gauge 9, and then judge the liquid level in the solution tank 1. When the pointer of the vacuum gauge 9 rotates greatly, it means that the liquid enters the second pipeline 8 and affects the detection data of the vacuum gauge 9, and then the system is shut down. In addition, the vacuum valve 6 can adjust the vacuum of the solution tank 1 in a timely manner. When the pressure in the solution tank 1 is higher than the preset value of the vacuum valve 6, the vacuum valve 6 is opened.

[0031] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
