Description

Technical Field

[0001] The utility model relates to the technical field of electroplating wastewater evaporation separation experiments, in particular to an electroplating wastewater evaporation separation experiment device capable of monitoring spray performance. Background Art

[0002] Electroplating wastewater contains a variety of heavy metal ions, such as zinc, copper, nickel, cadmium, etc. It has complex composition and strong pollution, and its treatment is relatively difficult. The traditional treatment methods of electroplating wastewater can be roughly divided into chemical precipitation, electrochemical, adsorption and physical methods. These methods have been applied in actual production and need to be tested through evaporation separation experimental equipment.

[0003] During the use of the above-mentioned equipment, the spray evaporation separation tower is usually made of stainless steel. Although this design meets the basic needs of the experiment to a certain extent, when conducting evaporation separation experiments, due to the opacity of stainless steel, it becomes difficult to observe the uniformity of the spray during the experiment. The uniformity of the spray is an important factor affecting the evaporation separation effect. If the spray condition cannot be observed intuitively, it is difficult to judge whether the experiment has achieved the expected effect. Whether the nozzle is blocked is also a key factor affecting the experimental results. However, in the existing spray evaporation separation tower, due to structural limitations, it is difficult to detect whether the nozzle is blocked in time. In order to check the condition of the nozzle, it is often necessary to disassemble the tower body, which not only increases the difficulty of experimental operation, but also prolongs the experimental time and reduces the efficiency of the experiment. This needs to be optimized and improved. Utility Model Content

[0049] Specifically, Figure 2 As shown, a flange 2 7 is welded to the outer top of the stainless steel tower body 1, and a connecting screw 8 is connected to the inner thread of the flange 2 7;

[0050] In this embodiment: the internal structure of flange 2 7 is the same as flange 1 601, and is provided with the same insertion groove 602 and positioning hole 603. The internal threaded hole is convenient for connecting with screws 8 to fit and fix with flange 1 601.

[0051] Specifically, Figure 3 As shown, the plug-in limit assembly 9 includes a plug-in card frame 901, and the plug-in card frame 901 is arranged at the left and right ends of the outer side of the flange 601, and the upper and lower walls inside the plug-in card frame 901 are fixedly connected with a rubber extrusion head 902;

The electroplating wastewater reaches the pressure nozzle 502 through the electroplating wastewater inlet pipe 501 in the middle of the visual tower top 2, and is atomized into a spray. After that, it exchanges heat with the hot air flowing from above, so that the water in the electroplating wastewater is gradually evaporated.

The internal structure of flange 2 7 is the same as that of flange 1 601, and is provided with the same plug-in slot 602 and positioning hole 603. The internal threaded hole is convenient for connecting the screw 8 and fitting with flange 1 601. The plug-in card frame 901 is stuck in the internal plug-in slot 602 of flange 1 601, and then the upper and lower flanges 1 601 and flange 2 7 can fit together, and the threaded holes are aligned.
