[0002] Ammonia water is a commonly used pH regulator and is widely used in the field of dosing in thermal systems of power plants and pH adjustment of desalted water. It not only protects thermal systems and desalted water systems of power plants by adjusting the pH value, but also does not cause deterioration of the quality of soda and water in the corresponding systems. Ammonia water is generally stored in a solution tank and added to the dosing point by a metering pump. In order to avoid the liquid level of the ammonia solution tank being too high, an overflow port and an overflow pipe are set on the tank body to discharge the ammonia water that may overflow into the drain.
[0003] In related technologies, such as Figure 5 As shown, due to the high volatility of ammonia water, the liquid level in the solution tank is lower than the overflow port under normal circumstances.

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0029] The following describes an ammonia solution tank overflow device according to an embodiment of the utility model with reference to the accompanying drawings.
[0030] like Figure 1-4 As shown, the ammonia solution tank overflow device 100 according to the embodiment of the utility model includes a solution tank 1 and an overflow pipe 2.
[0031] The solution tank 1 has a chamber, a liquid inlet and a liquid outlet, the liquid inlet is connected to the chamber so that ammonia water flows into the chamber through the liquid inlet to store ammonia water, and the liquid outlet is connected to the chamber so that ammonia water in the chamber flows out through the liquid outlet. Figure 1 As shown, the solution tank 1 can be cylindrical, rectangular, etc., and the liquid inlet and the liquid outlet are both connected to the solution tank 1, so that the ammonia water flows into the solution tank 1 through the liquid inlet and is stored in the solution tank 1. When the ammonia water is needed, the ammonia water is discharged out of the solution tank 1 through the liquid outlet.
[0032] The overflow pipe 2 includes a first section 21 and a second section 22 which are interconnected. The first section 21 is arranged in the solution tank 1 and at least a part of the first section 21 is located in the ammonia water. The first section 21 is provided with ammonia water so as to block the first section 21. The first section 21 includes a first tube 211, a second tube 212 and a third tube 213 which are connected in sequence. The first tube 211 and the third tube 213 extend in the up-down direction, the second tube 212 extends in the inside-outside direction, and both ends of the second tube 212 are respectively connected with the lower end of the first tube 211 and the lower end of the third tube 213. One end of the second section 22 passes through the solution tank 1 and is connected with the upper end of the third tube 213. The other end of the second section 22 extends out of the solution tank 1 and at least a part of the second section 22 is located above the third tube 213, so that when the ammonia water in the solution tank 1 is higher than a preset value, the ammonia water flows out of the solution tank 1 through the overflow pipe 2. Specifically, as Figure 1-4As shown, the first tube 211 and the third tube 213 are vertical tubes in the up-down direction, the second tube 212 is a vertical tube extending in the left-right direction, and the left and right ends of the second tube 212 are respectively connected to the lower end of the first tube 211 and the lower end of the third tube 213, thereby making the first section 21 generally U-shaped, the first section 21 is arranged in the solution tank 1 and at least partially located in the ammonia water, and the first section 21 is provided with ammonia water, so that the first section 21 is blocked by the ammonia water, the mixed gas in the ammonia solution tank 1 is isolated from the connection with the external environment of the solution tank 1, and the ammonia mist is prevented from being directly connected to the ammonia solution tank 1. In the case of being discharged into the environment, the second section 22 passes through the right side of the solution tank 1 and is connected to the upper end of the third section. Therefore, when the liquid level of the ammonia water in the solution tank 1 is higher than the upper end of the first tube 211, the ammonia water can flow out of the solution tank 1 through the first section 21 and the second section 22 to prevent the ammonia water level in the solution tank 1 from being too high. At least a part of the second section 22 is higher than the top of the first section 21. Therefore, the sealing effect of the overflow pipe on the mixed gas of air and ammonia in the solution tank 1 is improved, and it is ensured that the ammonia water can be discharged through the overflow port in time when the liquid level is too high, thereby ensuring the safety of the solution tank 1.
[0033] The ammonia solution tank overflow device 100 of the utility model embodiment is provided with a first section 21 and a second section 22. When the liquid level in the ammonia solution reaches a preset value, the excess ammonia solution can be discharged outside the solution tank 1 through the first section 21 and the second section 22, and the first section 21 is blocked by the ammonia solution to isolate the connection between the mixed gas in the ammonia solution tank 1 and the external environment of the solution tank 1, thereby avoiding the direct discharge of ammonia mist into the environment. When the solution tank 1 operates normally, the volatilization of ammonia mist in the tank to the outside of the tank is greatly reduced, thereby avoiding ammonia pollution and affecting the entire working environment.
[0034] In some embodiments, at least a portion of the upper end surface of the first tube 211 extends in the inner and outer directions and is inclined downward. Figure 1-4 As shown, the upper end surface of the first tube 211 is a wedge-shaped slope, which is conducive to the ammonia water in the box to enter the overflow pipe 2 and ensures the smoothness of the ammonia water flowing into the overflow pipe 2.
[0035] In some embodiments, the second section 22 includes a fourth tube 221, a fifth tube 222, and a sixth tube 223 that are connected in sequence. The fourth tube 221 and the sixth tube 223 extend in the up-down direction, the fifth tube 222 extends in the out-and-down direction and is connected to the upper ends of the fourth tube 221 and the sixth tube 223, respectively. The lower end of the fourth tube 221 is connected to the upper end of the third tube 213, so that the ammonia water flows out of the solution tank 1 through the fourth tube 221, the fifth tube 222, and the sixth tube 223, respectively. Specifically, as Figure 4As shown, the fourth tube 221 and the sixth tube 223 are vertical tubes extending in the up-down direction, the fifth tube 222 is a horizontal tube extending in the left-right direction, and the left and right ends of the fifth tube 222 are respectively connected to the upper end of the fourth tube 221 and the sixth tube 223, so that the second section 22 is an inverted U-shaped tube, and the lower end of the fourth tube 221 is connected to the upper end of the third tube 213, thereby making the setting of the second section 22 more reasonable, so that the solution tank 1 flows out through the overflow pipe 2.
[0036] In some embodiments, an overflow line (not shown in the figure) is provided in the inner circumference of the solution tank 1, the fifth tube 222 is flush with the overflow line in the horizontal direction, and the upper end of the first tube 211 is located below the overflow line, so that when the liquid level of the ammonia water in the chamber is higher than the overflow line, the ammonia water flows out of the chamber through the overflow tube 2. Specifically, the position of the overflow line can be set according to actual conditions and is a horizontal line extending in the left-right direction, the upper end of the fifth tube 222 is flush with the overflow line in the horizontal direction, and the upper end of the first tube 211 is located about 200 mm below the overflow line (in other words, the distance between the outlet of the upper end of the first tube 211 and the fifth tube 222 in the vertical direction is 200 mm), so that when the ammonia water in the solution tank 1 reaches the liquid inlet at the upper end of the first tube 211, the ammonia water can fill the U-shaped tube, which can seal the ammonia water in the solution tank 1, and when the liquid level of the ammonia water in the chamber reaches the overflow line or is higher than the overflow line, the ammonia water can be discharged from the solution tank 1 in time.
[0037] In some embodiments, the sixth tube 223 includes a first sub-tube 2231 and a second sub-tube 2232, both of which extend in the up-down direction and are arranged opposite to each other at intervals in the up-down direction, the upper end of the first sub-tube 2231 is connected to the fifth tube, the lower end surface of the first sub-tube 2231 is at the same height as the upper end surface of the first tube 211, and the cross-sectional area of the upper end portion of the second sub-tube 2232 gradually decreases from top to bottom. Specifically, as Figure 4As shown, the first sub-tube 2231 and the second sub-tube 2232 are both vertical tubes in the up-down direction. The first sub-tube 2231 and the second sub-tube 2232 are spaced apart in the up-down direction. The upper end of the first sub-tube 2231 is the inlet of the first sub-tube 2231, the lower end of the first sub-tube 2231 is the outlet of the first sub-tube 2231, the upper end of the second sub-tube 2232 is the inlet of the second sub-tube 2232, the lower end of the second sub-tube 2232 is the outlet of the second sub-tube 2232, and the outlet of the first sub-tube 2231 is horizontally aligned with the upper end surface of the first tube 211. The second sub-tube 2232 is arranged below the first sub-tube 2231, and the inlet of the second sub-tube 2232 and the outlet of the first sub-tube 2231 are spaced apart in the up-down direction. The cross-sectional area of the inlet end of the second sub-tube 2232 gradually decreases from top to bottom (in other words, the inlet end of the second sub-tube 2232 is funnel-shaped 7). Thus, siphoning is avoided to cause too little ammonia solution in the first section 21. At this stage, the first section 21 is used to isolate the mixed gas in the ammonia solution tank 1 from the external environment of the tank, thereby avoiding the direct discharge of ammonia mist into the environment.
[0038] In some embodiments, the liquid inlet is located at the top of the solution tank 1, and the liquid outlet is located at the bottom of the solution tank 1. Thus, it is convenient for the ammonia water to flow into the solution tank 1 through the liquid inlet and flow out of the solution tank 1 through the liquid outlet.
[0039] In some embodiments, the ammonia solution tank overflow device 100 further includes a liquid inlet pipe 3 and a liquid outlet pipe 4, wherein the liquid inlet pipe 3 is disposed at the top of the solution tank 1 and extends in the up-down direction, the liquid inlet pipe 3 is connected to the liquid inlet port so that the ammonia solution flows into the solution tank 1 through the liquid inlet pipe 3, and the liquid outlet pipe 4 is connected to the liquid outlet port of the solution tank 1 so that the ammonia solution flows out of the solution tank 1 through the liquid outlet pipe 4. Specifically, Figure 1-4 As shown, the liquid inlet pipe 3 and the liquid outlet pipe 4 are both L-shaped, and the liquid inlet pipe 3 is fixed to the top of the solution tank 1, the outlet of the liquid inlet pipe 3 extends into the solution tank 1 through the liquid inlet, the inlet of the liquid inlet pipe 3 can be connected to an external pipeline, thereby the solution tank 1 can be supplemented with ammonia water, the liquid outlet pipe 4 is arranged at the bottom of the solution tank 1, the inlet of the liquid outlet pipe 4 is connected to the outlet of the solution tank 1, thereby, the ammonia water in the solution tank 1 flows out of the solution tank 1 through the liquid outlet pipe 4.
[0040] In some embodiments, the lower end of the liquid inlet pipe 3 passes through the liquid inlet and is disposed adjacent to the bottom of the solution tank 1 so that the liquid inlet pipe 3 extends into the ammonia solution. Figure 1-4 As shown, the liquid inlet pipe 3 extends in the up-down direction and the outlet of the liquid inlet pipe 3 is adjacent to the bottom of the solution tank 1 , and the outlet of the liquid inlet pipe 3 is located inside the ammonia water in the solution tank 1 , thereby preventing the ammonia water in the solution tank 1 from flowing out of the solution tank 1 through the liquid inlet pipe 3 .
[0041] In some embodiments, the ammonia solution tank overflow device 100 further includes a metering pump 5, which is connected to the liquid outlet so that the ammonia solution in the solution tank 1 flows out of the solution tank 1 through the metering pump 5. Figure 1-4 As shown, the metering pump 5 is connected to the outlet of the liquid outlet pipe 4 , so that the ammonia water in the solution tank 1 is discharged out of the solution tank 1 through the metering pump 5 .
[0042] In some embodiments, Figure 1-4 As shown, the ammonia solution tank overflow device 100 further includes a drain ditch 6, which is provided at one side of the solution tank 1, and the overflow pipe 2 is connected to the drain ditch 6, so that the ammonia solution flowing out through the overflow pipe 2 is discharged through the drain ditch 6. Thus, the excess ammonia solution in the solution tank 1 is discharged through the drain ditch 6.
[0043] The following is based on the attached Figure 1-4 As shown, the ammonia solution tank overflow device 100 according to the embodiment of the utility model is specifically described.
[0044] The ammonia solution tank overflow device 100 includes two parts, one inside the solution tank 1 and one outside the solution tank 1. The first section 21 is arranged inside the solution tank 1 and connected to the overflow port of the solution tank 1. The pipe mouth of the first section 21 inlet is provided with a wedge-shaped slope, which is conducive to the ammonia solution in the solution tank 1 entering the overflow pipe 2; at the same time, the vertical distance H between the highest point of the suction wedge-shaped slope of the first section 21 in the solution tank 1 and the lowest point of the overflow port is set to a height of about 200 mm. The above arrangement not only ensures the sealing effect of the first section 21 on the mixed gas of air and ammonia in the solution tank 1, but also ensures that the ammonia solution can be discharged through the overflow port in time when the liquid level is too high, thereby ensuring the safety of the solution tank 1.
[0045] The first sub-tube 2231 and the second sub-tube 2232 are arranged outside the solution tank 1, and the upper end of the second sub-tube 2232 is provided with a funnel 7, and the lower end of the second sub-tube 2232 is connected to the drainage ditch 6. The elevation of the funnel 7 is consistent with the elevation of the highest point of the suction wedge-shaped groove of the first section 21 in the solution tank 1. The above arrangement can ensure that the solution in the solution tank 1 is discharged into the drainage ditch 6 when the solution is too high. At the same time, the high-level venting (the setting of the funnel 7) is set to avoid the siphon effect of the first section 21 and the second section 22 inside, and always ensure that there is liquid in the first section 21, isolating the air circulation between the solution tank 1 and the external environment, and greatly reducing the volatilization area of ammonia water connected to the outside from S1 of the entire ammonia solution tank 1 to S2, which greatly reduces the volatilization of ammonia water to the external environment.
[0046] (1) Figure 3 and Figure 4 As shown, when the liquid level of ammonia solution tank 1 is too high:
[0047] At this time, the ammonia level in the solution tank 1 is higher than the overflow port. According to the connection distance, the ammonia in the solution tank 1 enters the overflow port through the first section 21 and flows into the emptying funnel 7 through the second section 22 and is discharged into the drain ditch 6 until the liquid level is lower than the height of the overflow pipe 2.
[0048] (2) Figure 2 As shown, when the liquid level of the ammonia solution tank 1 is between the suction wedge-shaped groove of the first section 21 and the overflow port, the liquid surface of the ammonia solution tank 1 at this stage isolates the internal mixed gas from the connection with the outside of the solution tank 1, avoiding the direct discharge of ammonia mist into the environment.
[0049] (3) Figure 1 As shown, when the liquid level of the ammonia solution tank 1 is lower than the first section 21 suction wedge groove
[0050] Due to the arrangement of the second section 22 and the funnel 7 outside the solution tank 1, the liquid in the first section 21 is prevented from being too little due to siphonage. At this stage, the mixed gas in the ammonia solution tank 1 is isolated from the external environment of the solution tank 1 by the first section 21, thereby preventing the ammonia mist from being directly discharged into the environment. Figure 5 .
[0051] In summary, the utility model provides an overflow pipe 2 in the ammonia solution tank 1, thereby ensuring normal solution overflow and preventing ammonia mist in the solution tank 1 from volatilizing to the outside of the solution tank 1, thereby causing ammonia mist pollution and affecting the working environment.
