And this kind of acidic wastewater containing heavy metals is treated by sulfidation-gypsum-iron salt neutralization process. The flow of the sulfidation section is as shown in Figure 4
[0003] The process is introduced as follows: first, the dirty acid pump b transports the dirty acid in the dirty acid stock solution tank a to the hydrogen sulfide absorption tower c, and reacts with the hydrogen sulfide gas extracted from the top of the sulfidation reaction tank e by the fan, and the reacted liquid flows into the sulfidation reaction tank e and reacts with the sodium sulfide from the sodium sulfide high-level adding tank d. Because sodium sulfide is high-level added, the amount of sodium sulfide entering 1-3# sulfidation reaction tank e is constant. If the amount of dirty acid entering 1-3# reaction tank e is not constant, the sulfidation reaction in 1-3# reaction tank e will be different, and the heavy metals in the dirty acid will not be removed uniformly, so it is necessary to frequently adjust the electric valve of 1-3# sulfidation reaction tank e or the manual valve of the sodium sulfide high-level adding tank d, the valve is operated frequently, and the water quality of 1-3# sulfidation reaction tank e is quite different. Therefore, in order to facilitate operation and ensure the consistency of the water quality of each sulfidation reaction tank e, the liquid from the hydrogen sulfide absorption tower c needs to be evenly distributed to 1-3# sulfidation reaction tank e.

[0025] The utility model will be described in further detail below in combination with the drawings and specific embodiments, but the protection scope of the utility model is not limited to the content.
[0026] As shown in Figure 1 and Figure 2 , the application provides a uniform shunt device, which comprises a steady flow tank 1, a shunt pipe 2 and a liquid inlet pipe 3.
[0027] The bottom of the steady flow tank 1 is provided with at least one shunt pipe 2, the number of shunt pipes 2 is matched with the number of reaction tanks 4, specifically, three shunt pipes 2 are arranged in a circumferential array, the liquid inlet end of any one of the shunt pipes 2 is inserted into the steady flow tank 1, and the insertion depth is adjustable, the liquid outlet end of the shunt pipe 2 is connected with the reaction tank 4 through a pipeline, and a valve 5 is arranged on the connecting pipeline.
[0028] The side surface of the steady flow tank 1 is provided with a liquid inlet pipe 3, the liquid inlet end of the liquid inlet pipe 3 is connected with the absorption tower 6 through a pipeline, the liquid outlet end of the liquid inlet pipe 3 is inserted into the steady flow tank 1 and is arranged in a curved manner upwards, and a baffle 7 is arranged above the liquid outlet end of the liquid inlet pipe 3.
[0029] When working, the waste liquid of the absorption tower 6 is introduced into the liquid inlet pipe 3 through a pipeline, then introduced into the steady flow tank 1 through the liquid inlet pipe 3, and then uniformly distributed to each shunt pipe 2 through the steady flow tank 1, since the pressure of the liquid inlet end of each shunt pipe 2 is basically the same, the flow of each shunt pipe 2 is effectively ensured to be the same.
[0030] Meanwhile, the liquid outlet end of the liquid inlet pipe 3 is arranged in a curved manner upwards, so that the introduced waste liquid does not have a large impact on the waste liquid in the steady flow tank 1, and the flow of each shunt pipe 2 is further ensured to be the same; and the baffle 7 is arranged above the liquid outlet end of the liquid inlet pipe 3, which effectively avoids the problem that the waste liquid is splashed out of the steady flow tank 1.
[0031] Furthermore, by adjusting the depth of the diversion pipe 2 inserted into the flow stabilizing box 1, the different flow rates caused by the different pipe lengths of the diversion pipe 2 to each reaction tank 4 can be balanced, which helps to ensure that the flow rate of each diversion pipe 2 is the same.
[0032] Furthermore, if three pipes are connected horizontally from the bottom of the hydrogen sulfide absorption tower 6 and respectively into the 1-3# sulfidation reaction tank 4, the purpose of uniform liquid separation can also be achieved. However, the pipelines are too numerous and too long. This application adopts a uniform liquid separation device, which can reduce costs.
[0033] In this embodiment, the bottom of the current stabilizing box 1 is provided with a through hole whose diameter matches the outer diameter of the diverter pipe 2. The diverter pipe 2 passes through the through hole, and two locking nuts 8 are threaded onto the diverter pipe 2. One locking nut 8 is located inside the current stabilizing box 1, and the other locking nut 8 is located outside the current stabilizing box 1. When adjusting the depth of the diverter pipe 2 inserted into the current stabilizing box 1, the two locking nuts 8 can be loosened, making the adjustment more convenient. When the two locking nuts 8 are tightened, the two locking nuts 8 clamp the bottom of the current stabilizing box 1 from the top and bottom sides respectively, thereby achieving a sealing effect.
[0034] In this embodiment, a sealing gasket 9 is provided between the locking nut 8 located inside the flow stabilizer 1 and the inner bottom surface of the flow stabilizer 1, which effectively prevents the waste liquid in the flow stabilizer 1 from flowing out from between the diversion pipe 2 and the hole wall.
[0035] In this embodiment, the baffle 7 is a downward-curved arc shape. After the waste liquid is sprayed out from the inlet pipe 3, it hits the arc-shaped baffle 7 and is dispersed, which effectively avoids the waste liquid flowing down in streams and causing excessive impact on the waste liquid in the flow stabilizing box 1, and further ensures that the flow rate of each diversion pipe 2 is the same.
[0036] In some specific implementations, such as Figure 3 As shown, the top of the flow stabilizer 1 is provided with a cover plate 13, and the cover plate 13 is provided with a first vent hole 10. The bottom of the cover plate 13 is provided with a conduit 11 that matches the position of the first vent hole 10. The side wall of the conduit 11 is provided with a second vent hole 14. The conduit 11 is provided with a hollow float ball 12, which is made of rubber material. When the flow stabilizer 1 is basically full, the waste liquid in the flow stabilizer 1 enters the conduit 11 through the second vent hole 14, and then causes the float ball 12 to float up and rise with the rise of the liquid level in the flow stabilizer 1. When the float ball 12 is in contact with the first vent hole 10, it blocks the first vent hole 10, effectively avoiding the technical problem of waste liquid overflowing from the flow stabilizer 1.
