[0037] Example:

[0038] See also Figures 1 to 3 The spray rod for spraying the pre-concentrator of the waste hydrochloric acid regeneration device in the preferred embodiment of the utility model has multiple nozzle structures on the outer cover and the inner rod, and adopts a return design, so that the device can quickly spray the waste hydrochloric acid solution into the container for treatment through multiple nozzles.

[0039] Specifically, the spray rod in the preferred embodiment of the utility model includes an inner rod 100 and an outer cover 200; a feed port 101 and a discharge port 107 are respectively formed at both ends of the inner rod 100 along its axial direction, and a first channel 102 is formed inside the inner rod 100; the outer cover 200 is sleeved on the outer periphery of the inner rod 100, and a second channel 201 is formed between the inside of the outer cover 200 and the outer periphery of the inner rod 100, and a plurality of nozzles 202 are formed on the outer cover 200; at the same time, a material guiding structure is arranged in the inner rod 100, and the first channel 102 and the second channel 201 are connected through the material guiding structure; and the first channel 102 and the discharge port 107 are also connected through the material guiding structure.

[0040] During actual use, the operator first uses a suction pump to connect the feed port 101 to introduce the waste hydrochloric acid solution into the interior of the inner rod 100, and then the hydrochloric acid solution is guided to the guide structure through the first channel 102. At this time, since the guide structure is connected to the discharge port 107 and the second channel 201, part of the hydrochloric acid solution will be directly sprayed out from the discharge port 107, or enter the second channel 201 and sprayed out from the nozzle 202, so as to realize axial and circumferential two-way discharge, thereby greatly improving the spraying efficiency.

[0041] In more detail, Figure 1As shown in , the spray rod in the preferred embodiment of the utility model includes a material guide structure including a limit ring 103, a guide block 105 and a guide ring 104; the limit ring 103 is arranged at one end of the inner rod 100 close to the discharge port 107, the guide ring 104 is clamped and arranged in the limit ring 103, the guide block 105 is assembled in the guide ring 104, one end of the guide block 105 is open, and the other end is connected with the discharge port 107 through the guide ring 104; and the guide ring 104 is connected with the first channel 102.

[0042] Furthermore, in order to allow the hydrochloric acid solution to better enter the guide ring 104, the main projection surface of the end of the guide block 105 away from the discharge port 107 is trumpet-shaped. The trumpet-shaped variable diameter structure can effectively increase the flow rate and pressure of the solution here, and prevent the occurrence of problems such as solution accumulation.

[0043] In addition, in the preferred embodiment of the present invention, the nozzle 202 includes a mesh plate and a nozzle. The nozzle is assembled on one side of the mesh plate, and a plurality of through holes are formed on the mesh plate.
