Description

Technical Field

[0001] The utility model relates to the technical field of electroplating wastewater treatment equipment, in particular to an electroplating wastewater evaporation circulation treatment device. Background Art

[0002] Electroplating wastewater refers to wastewater generated during the electroplating production process, mainly including plated parts cleaning water, waste plating solution, and water used in the washing workshop. This wastewater contains harmful components such as heavy metal ions, cyanide, acids and alkalis. If it is directly discharged into the environment, it will cause serious pollution and harm to the soil, water bodies and ecosystems. Evaporation and concentration of electroplating wastewater is one of the important processes for treating electroplating wastewater. It uses the principle of evaporation to evaporate the water in the electroplating wastewater, thereby reducing the amount of wastewater and concentrating harmful substances for further treatment or recycling.

[0003] In the prior art, electroplating wastewater enters the evaporator and is heated by a heating device to make the wastewater reach a boiling state, and then the water molecules are converted into water vapor in the boiling state, and finally, the water vapor is condensed into water through a condenser; in order to facilitate the reduction of the boiling point of the water vapor, a vacuum pump is generally used to reduce the internal pressure in the evaporator, resulting in a fast flow rate of the water vapor when it is discharged from the pipeline in a low-pressure environment and a high heating temperature. After directly entering a single condenser, the water vapor cannot meet the cooling requirements of the steam in the case of rapid flow of the water vapor, which affects the treatment effect of the electroplating wastewater. Therefore, we propose an electroplating wastewater evaporation and circulation treatment device to solve the above problems. Utility Model Content

[0025] A cooling mechanism is provided inside the condensing water tank 7, and the cooling mechanism includes two sealed partitions 8. The inner wall of the condensing water tank 7 is fixedly connected to the outer walls of the two sealed partitions 8. A plurality of disc pipes 9 are fixedly connected between the two sealed partitions 8. The plurality of disc pipes 9 increase the flow path of water vapor and increase the cooling time. An inlet pipe 10 and an outlet pipe 11 are fixedly connected to the outer wall of the condensing water tank 7. One end of the inlet pipe 10 and the outlet pipe 11 are fixedly connected to the same condensing unit. The existing pump body transports the cooling water to between the two sealed partitions 8 through the inlet pipe 10.

[0026] A circulation pipe 12 is fixedly connected to the outer wall of the condensing water tank 7, and one end of the circulation pipe 12 is fixedly connected to the outer wall of the circulation box 1. The water vapor that has not been completely cooled re-enters the circulation box 1 through the circulation pipe 12 for re-circulation and cooling. A fixed pipe 13 is fixedly connected between the water collecting pipe 5 and the condensing water tank 7.

[0027] A drainage mechanism is provided inside the condensate water tank 7, and the drainage mechanism includes a drain pipe 14, one end of which is fixedly communicated with the outer wall of the condensate water tank 7, and a connecting plate 16 is fixedly connected to the inside of the condensate water tank 7, and a plurality of through holes 17 are evenly provided on the outer wall of the connecting plate 16. Water droplets formed in the disc tube 9 flow into the inside of the condensate water tank 7 through the plurality of through holes 17.

[0028] Working principle: When in use, the water vapor in the evaporator enters the circulation box 1 from the water vapor docking pipe 2, and is initially cooled along the spiral blades 3. The cooled water droplets drip into the water collecting pipe 5 along the spiral blades 3, and the water in the water collecting pipe 5 enters the condensing water tank 7 along the fixed pipe 13. The remaining water vapor enters the condensing water tank 7 along the curved pipe 4 and the connecting pipe 6, and is discharged from the multiple disc pipes 9. The cooling water is transported to between the two sealing partitions 8 through the existing pump body through the water inlet pipe 10 to cool the water vapor in the disc pipe 9, and the water after heat transfer re-enters the condensing unit along the water outlet pipe 11 for cooling, and is then transported by the pump body to achieve For recycling, the water droplets formed by the partially cooled water vapor are concentrated in the condensate tank 7, and as the liquid level rises, the float on the float level gauge 18 is driven to rise. After reaching a certain liquid level, the electronic valve 15 opens to discharge part of the condensate through the drain pipe 14, but a certain liquid level height is guaranteed to discharge part of the condensate. Due to the obstruction of the condensate, the water vapor that has not been completely cooled re-enters the circulation box 1 through the circulation pipe 12 for re-circulation and cooling. After the subsequent completely evaporated water vapor is completely condensed, the valve on the exhaust pipe is opened to release the pressure in the circulation box 1, the evaporator and the condensate tank 7.
