Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and particularly to a device for recycling concentrated brine from printing and dyeing wastewater. Background Art

[0002] The device for recycling concentrated brine from printing and dyeing wastewater is mainly used to extract the concentrated brine from printing and dyeing wastewater, so as to facilitate subsequent secondary use.

[0003] Currently, the recycling of concentrated brine from printing and dyeing wastewater mainly uses high-temperature steam to heat and evaporate the water in the wastewater. What remains after evaporation is a concentrated salt solution (i.e., concentrated brine). Then, the steam is cooled into liquid water through a cooler or condenser, so that water recovery and salt concentration can be achieved. However, additional environmental pollution or waste will be generated during the process, such as chemical solvents, refrigerant substances, etc. These substances may pose risks to the environment and health, and large cooling equipment is only suitable for specific environmental conditions or scales, such as equipment in large industrial production, and the cost is too high for small-scale or non-industrial application scenarios.

[0035] The following is a further detailed description of this application in conjunction with the attached Figure 1-6 drawings.

[0036] An embodiment of this application discloses a device for recycling concentrated brine from printing and dyeing wastewater.

[0037] Referring to Figure 1 , as shown in Figure 2, a device for recycling concentrated brine from printing and dyeing wastewater includes a device bottom plate 1. The top of the device bottom plate 1 is fixedly connected to the bottom of a heating plate 11. The connection end on the side wall of the heating plate 11 horizontally penetrates through the side wall of a support plate 21 Figure 2 As shown in the figure, a steam recovery mechanism 2 is arranged on the top of the device bottom plate 1.

[0038] The staff horizontally places the device bottom plate 1 on the ground, then pours the printing and dyeing wastewater into the interior of the reaction box 23, and then starts the heating plate 11. The heating plate 11 will heat the bottom of the reaction box 23.

[0039] Referring toFigure 5 ,6, The steam recovery mechanism 2 includes a first water collecting tank 28. One end of the side wall of the first water collecting tank 28 close to the first water collecting tank 28 is fixedly connected to the water baffle 29, so as to support the side wall of the first water collecting tank 28 through the water baffle 29. The water outlet 210 is formed through the bottom of the first water collecting tank 28, so that the water inside the first water collecting tank 28 can flow out from the water outlet 210. The bottom of the first water collecting tank 28 is fixedly connected to the top of the second water collecting tank 211. The water outlet 210 is located above the second water collecting tank 211, so that the water inside the first water collecting tank 28 can flow into the second water collecting tank 211. One end of the second water collecting tank 211 away from the first water collecting tank 28 is fixedly connected to the connecting end of the confluence tank 212 close to the second water collecting tank 211, so that the water flow can flow into the confluence tank 212.

[0040] After the heating plate 11 continuously heats the reaction box 23, the printing and dyeing wastewater inside the reaction box 23 will boil, and the water molecules therein will vaporize to form water vapor rising. The rising water vapor will adhere to the bottom of the condensation inclined plate 25. As the water vapor continuously adheres, it will condense into water droplets. Since the condensation inclined plate 25 has an angle on both sides, when the water droplets continuously condense, they will slide to both sides and finally fall into the first water collecting tank 28 from both sides for collection.

[0041] Refer to Figure 3 ,4, The steam recovery mechanism 2 further includes a support plate 21 fixedly connected to the top of the device bottom plate 1. Both ends of the horizontal plate 22 are fixedly connected between the two support plates 21, so as to make the connection more coherent through the horizontal plate 22. Both sides of the reaction box 23 close to the support plate 21 are fixedly connected between the two support plates 21 to fix the reaction box 23. The reaction box 23 is made of metal material and has good thermal conductivity. One end of the vertical support column 24 close to the horizontal plate 22 is fixedly connected to the top of the horizontal plate 22, so that the vertical support column 24 vertically supports the horizontal plate 22. The top of the vertical support column 24 is fixedly connected to the bottom of the condensation inclined plate 25. The bottom of the support column 1 26 is fixedly connected to the top of the device bottom plate 1. One end of the support column 2 27 close to the device bottom plate 1 is fixedly connected to the top of the device bottom plate 1, so that the structure is more stable. One end of the support column 1 26 away from the device bottom plate 1 is fixedly connected to one side of the first water collecting tank 28 close to the support column 1 26, so as to vertically support the first water collecting tank 28 through the support column 1 26. One side of the support column 2 27 away from the device bottom plate 1 is fixedly connected to one side of the second water collecting tank 211 close to the support column 2 27, so as to vertically support the second water collecting tank 211 through the support column 2 27. The bottom of the confluence tank 212 is fixedly connected to the top of the support column 3 213. The bottom of the support column 3 213 is fixedly connected to the top of the device bottom plate 1. A collecting box 3 is arranged on one side of the confluence tank 212 away from the second water collecting tank 211. The collecting box 3 is located at the bottom of the water outlet of the confluence tank 212 to store the collected water.

[0042] Subsequently, water droplets converge into a water flow in the first water collecting tank 28. The water flow flows through the water outlet 210 in the first water collecting tank 28 into the second water collecting tank 211, then flows through the second water collecting tank 211 into the confluence tank 212, and then flows through the confluence tank 212 into the collection box 3 for storage, thus completing the natural collection of water vapor. After distillation, what remains in the reaction box 23 is a high-concentration salt molecule solution.

[0043] Among them, the heating plate 11 is a prior art, and its structural principle will not be elaborated herein.

[0044] The implementation principle of the device for recycling concentrated brine from printing and dyeing wastewater in the embodiment of the present application is as follows: The staff starts the heating plate 11 to heat the printing and dyeing wastewater in the reaction box 23, converges the water vapor into water droplets through the condensation inclined plate 25, and then collects the water droplets through the first water collecting tank 28. The first water collecting tank 28 then conveys the water to the second water collecting tank 211 through the water outlet 210, and the second water collecting tank 211 finally stores the water in the collection box 3 through the confluence tank 212, thus completing the collection of water vapor for recycling concentrated brine. What remains inside the reaction box 23 is the concentrated salt molecule solution.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
