Description

Technical Field

[0001] This utility model relates to the field of chemical equipment, specifically to a water replenishment device for a dual scrubbing tower. Background Technology

[0002] The water supply tank of the scrubbing tower is the core equipment of the waste gas treatment system. The water supply tank is connected to the scrubbing tower through pipelines. Water pumps deliver water from the water supply tank to the scrubbing tower. The water supply tank is equipped with a magnetic level gauge and a water supply pipe with a control valve. When the level gauge is lower than the first set value, the control valve opens and the water supply pipe replenishes water to the water supply tank. When the level gauge is higher than the second set value, the control valve closes and water replenishment stops.

[0003] The existing dual scrubbing tower uses two water supply tanks that are independently supplied with water. The magnetic float level gauge is prone to occasional failures such as signal drift and mechanical jamming during long-term operation. When the magnetic float level gauge in one of the water supply tanks fails, real-time level monitoring under fault conditions cannot be achieved. Utility Model Content

[0004] In view of the above-mentioned problems and to overcome at least one deficiency, this utility model proposes a water replenishment device for a dual scrubbing tower.

[0005] The technical solution adopted by this utility model is as follows:

[0006] A water supply device for a dual scrubbing tower includes:

[0007] First water tank;

[0008] The first magnetic level gauge is installed on the first water supply tank;

[0009] The first water supply pipe is connected at one end to the lower part of the first water replenishment tank and at the other end to the first washing tower.

[0010] The first water pump is installed on the first water supply pipe;

[0011] Second water tank;

[0012] The second magnetic level gauge is installed on the second water supply tank;

[0013] The second water supply pipe is connected at one end to the lower part of the second water supply tank and at the other end to the second washing tower.

[0014] The second water pump is installed on the second water supply pipe;

[0015] The U-shaped tube has a middle section and two vertical sections. The middle section is located above the two water supply tanks, and the two vertical sections extend into the first water supply tank and the second water supply tank, respectively.

[0016] This application utilizes the siphon principle, connecting the first and second water supply tanks via a U-shaped tube to maintain the liquid levels in both tanks at the same level. In this connected state, the liquid level measured by the magnetic level gauge in the first tank can be considered the liquid level in the second tank, and vice versa. Even if one magnetic level gauge malfunctions, real-time liquid level monitoring can be achieved using the other gauge.

[0017] In existing technologies, it has been found that two water replenishment tanks suffer from problems such as delayed water replenishment and high energy consumption. This application addresses this issue by using siphon-based balanced water replenishment: achieving liquid level synchronization without the need for external power, thus reducing energy consumption.

[0018] In this application, "vertical" in the vertical segment is a general term and is not limited to being completely perpendicular to the horizontal plane. The vertical segment can also be set at an angle.

[0019] This application uses a U-shaped tube.

[0020] In practical applications, the control system of the traditional water replenishment device can be improved without changing it. Simply adding a U-shaped pipe can achieve better control and improve the stability of the entire system.

[0021] In one embodiment of the present invention, the first water tank has a first water supply pipe and a first control valve; the second water tank has a second water supply pipe and a second control valve.

[0022] In one embodiment of the present invention, both the first water tank and the second water tank are provided with a drain valve at their lower parts.

[0023] In one embodiment of the present invention, an overflow valve is provided on the upper part of both the first water tank and the second water tank, and the overflow valve is used to connect to the water supply device through a pipeline.

[0024] The water replenishment device also includes a controller (PLC). In practical applications, the water replenishment device of this application has a fault response mechanism that can be implemented as follows:

[0025] For example, if the second magnetic level gauge in the second water replenishment tank malfunctions while the second water replenishment tank continues to be filled, the first magnetic level gauge in the first water replenishment tank can accurately report the water level information to the PLC because the first and second water replenishment tanks are connected. When the water level is 600mm above the set value, the controller automatically opens the drain valve of the first water replenishment tank to drain the water and prevent it from becoming too high. If the water level continues to rise to 650mm, the two overflow valves will open to drain the water, further ensuring system safety. If the water level continues to climb to 700mm, the controller will trigger an alarm to alert staff so that they can handle the abnormal situation promptly and avoid more serious consequences caused by excessively high water levels.

[0026] The overflow valve of this application is used to connect to a water supply device through a pipeline, that is, the overflow liquid is returned to the circulation system, which can reduce water waste.

[0027] In one embodiment of this utility model, filter heads can be detachably installed at the lower ends of both vertical sections.

[0028] Filter heads come in various forms, such as those screwed into a vertical section and containing at least one filter screen. 316L stainless steel is a preferred material to withstand the highly corrosive environment of the scrubbing tower.

[0029] In one embodiment of this utility model, the distance between the lower end of the vertical section and the bottom wall of the corresponding water replenishment tank is 50mm~150mm.

[0030] This depth setting is to prevent impurities at the bottom of the water tank from entering the U-tube and affecting the normal operation of the system, while also ensuring that the liquid level can still be connected through the U-tube when the water tank level is low.

[0031] In one embodiment of this utility model, the inner diameter of the U-shaped tube is 20mm~100mm.

[0032] In one embodiment of the present invention, the U-shaped tube further includes a vacuum section connected to the middle section, and a shut-off valve is installed on the vacuum section.

[0033] To connect the first and second water supply tanks, the U-shaped tube needs to be filled with water. A vacuum section is installed to connect to an external vacuum device to evacuate the U-shaped tube. At this time, water from the water supply tank can enter and fill the U-shaped tube. Once the U-shaped tube is full, the shut-off valve is closed.

[0034] In one embodiment of the present invention, a support component is further included, the upper end of which contacts the middle section, and the support component has a height adjustment element.

[0035] The distance between the lower end of the vertical section and the bottom wall of the water tank can be adjusted by the height adjustment element, which can be adjusted as needed, making the device more adaptable.

[0036] In one embodiment of the present invention, the support assembly further includes a support frame, the upper end of which cooperates with the middle section, and the lower end of which is mounted on a height adjustment element.

[0037] The height adjustment element is a jack.

[0038] In practical applications, it can be used as a common jack structure for automobiles.

[0039] The beneficial effects of this utility model are as follows: This application utilizes the siphon principle, connecting the first and second water supply tanks via a U-shaped tube, thereby ensuring that the liquid levels in both tanks remain at the same level. In this connected state, the liquid level measured by the magnetic level gauge in the first water supply tank can be considered the liquid level in the second water supply tank, and vice versa. Even if one magnetic level gauge malfunctions, real-time liquid level monitoring can be achieved through the other magnetic level gauge in the faulty state. Attached Figure Description

[0048] The present invention will now be described in detail with reference to the accompanying drawings.

[0049] Example 1

[0050] like Figure 1 As shown, a water supply device for a dual scrubbing tower includes:

[0051] First water tank 11;

[0052] The first magnetic level gauge 111 is installed in the first water supply tank 11;

[0053] The first water supply pipe 112 is connected at one end to the lower part of the first water replenishment tank 11, and at the other end to the first washing tower 31.

[0054] The first water pump 21 is installed on the first water supply pipe 112;

[0055] Second water tank 12;

[0056] The second magnetic level gauge 121 is installed on the second water supply tank 12;

[0057] The second water supply pipe 122 is connected at one end to the lower part of the second water supply tank 12, and at the other end to the second washing tower 32.

[0058] The second water pump 22 is installed on the second water supply pipe 122;

[0059] The U-shaped tube 4 has a middle section 41 and two vertical sections 42. The middle section 41 is located above the two water supply tanks, and the two vertical sections 42 extend into the first water supply tank 11 and the second water supply tank 12, respectively.

[0060] This application utilizes the siphon principle, connecting the first water supply tank 11 and the second water supply tank 12 via a U-shaped tube 4, thereby ensuring that the liquid levels in both tanks remain at the same level. In this connected state, the liquid level measured by the magnetic level gauge in the first water supply tank 11 can be considered the liquid level in the second water supply tank 12, and vice versa. That is, even if one magnetic level gauge malfunctions, real-time liquid level monitoring can be achieved through the other magnetic level gauge in the faulty state.

[0061] In existing technologies, it has been found that two water replenishment tanks suffer from problems such as delayed water replenishment and high energy consumption. This application addresses this issue by using siphon-based balanced water replenishment: achieving liquid level synchronization without the need for external power, thus reducing energy consumption.

[0062] In this application, the verticality of the vertical segment 42 is a general term and is not limited to being completely perpendicular to the horizontal plane. The vertical segment 42 can also be set at an angle.

[0063] This application uses a U-shaped tube 4.

[0064] In practical applications, the control system of the traditional water replenishment device can be improved without changing it. Simply adding a U-shaped pipe can achieve better control and improve the stability of the entire system.

[0065] In this embodiment, the first water supply tank 11 has a first water supply pipe 113 and a first control valve 114; the second water supply tank 12 has a second water supply pipe 123 and a second control valve 124.

[0066] In this embodiment, both the first water tank 11 and the second water tank 12 are provided with a drain valve 101 at their lower parts.

[0067] In this embodiment, both the first water supply tank 11 and the second water supply tank 12 are provided with an overflow valve 102 at their upper parts. The overflow valve 102 is used to connect to the water supply device through a pipeline.

[0068] The water replenishment device also includes a controller (PLC). In practical applications, the water replenishment device of this application has a fault response mechanism that can be implemented as follows:

[0069] For example, when the second magnetic level gauge 121 of the second water replenishment tank 12 malfunctions and the second water replenishment tank 12 continues to add liquid, since the first water replenishment tank 11 and the second water replenishment tank 12 are connected, the first magnetic level gauge 111 of the first water replenishment tank 11 can accurately feed back the liquid level information to the PLC. When the liquid level is higher than the set value of 600mm, the controller automatically opens the drain valve 101 of the first water replenishment tank 11 to drain the liquid to prevent the liquid level from being too high. If the liquid level continues to rise to a height of 650mm, the two overflow valves 102 will open to drain the liquid, further ensuring system safety. If the liquid level continues to climb to 700mm, the controller will trigger an alarm to remind staff to handle the abnormal situation in a timely manner and avoid more serious consequences caused by excessive liquid level.

[0070] The overflow valve 102 of this application is used to connect to a water supply device through a pipeline, that is, the overflow liquid is returned to the circulation system, which can reduce water waste.

[0071] In this embodiment, filter heads 421 can be detachably installed at the lower ends of both vertical sections 42.

[0072] The filter head 421 can take many forms, such as being screwed onto the vertical section 42 and having at least one filter screen inside. The preferred material is 316L stainless steel to withstand the highly corrosive environment of the scrubbing tower.

[0073] In practical applications, the distance between the lower end of the vertical section 42 and the bottom wall of the corresponding water supply tank is 50mm to 150mm. In this embodiment, it is 100mm. This depth setting is to prevent impurities at the bottom of the water supply tank from entering the U-shaped pipe 4 and affecting the normal operation of the system, while also ensuring that the liquid level can still be connected through the U-shaped pipe 4 when the water level in the tank is low.

[0074] In this embodiment, the inner diameter of the U-shaped tube 4 is 20mm~100mm.

[0075] This embodiment is used in an RTO scrubbing tower system of a chemical plant to treat factory waste gas.

[0076] Compared to the traditional independent two-tank structure, the effect of adopting the solution in this application is as follows: the water level fluctuation in the water tank is reduced from ±50mm to ±5mm, and the washing efficiency is improved by 15%; approximately 500 tons of water are saved annually, and the replacement cycle of the magnetic level gauge is extended from 12 months to 3 years; under extreme working conditions (such as valve jamming), the system automatically protects against shutdown accidents.

[0077] Example 2

[0078] like Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the U-shaped tube 4 also includes a vacuum section 411 connected to the intermediate section 41, and a shut-off valve 412 is installed on the vacuum section 411.

[0079] To connect the first water tank 11 and the second water tank 12, the U-tube 4 needs to be filled with water. A vacuum section 411 is provided to connect to an external vacuum device to evacuate the U-tube 4. At this time, water from the water tank can enter and fill the U-tube 4. After the U-tube is filled, the shut-off valve 412 is closed.

[0080] Example 3

[0081] like Figure 3 As shown, the difference between this embodiment and embodiment 1 or embodiment 2 is that the U-tube 4 also includes a vacuum section 411 connected to the intermediate section 41, and a shut-off valve 412 is installed on the vacuum section 411.

[0082] To connect the first water tank 11 and the second water tank 12, the U-tube 4 needs to be filled with water. A vacuum section 411 is provided to connect to an external vacuum device to evacuate the U-tube 4. At this time, water from the water tank can enter and fill the U-tube 4. After the U-tube is filled, the shut-off valve 412 is closed.

[0083] In this embodiment, a support component 5 is also included, the upper end of which contacts the middle section 41, and the support component 5 has a height adjustment element 51.

[0084] The distance between the lower end of the vertical section 42 and the bottom wall of the water tank can be adjusted by the height adjustment element 51, which can be adjusted as needed, making the device more adaptable.

[0085] In this embodiment, the support assembly 5 further includes a support frame 52, the upper end of which engages with the middle section 41, and the lower end of which is mounted on a height adjustment element 51; the height adjustment element 51 is a jack. In practical applications, it can be a common jack structure used in automobiles.

[0086] The above description is only a preferred embodiment of the present utility model and does not limit the scope of patent protection of the present utility model. Any equivalent structural transformations made based on the content of the present utility model specification and drawings, whether directly or indirectly applied to other related technical fields, are similarly included within the scope of protection of the present utility model.
