Description

Technical Field

[0001] The utility model relates to the technical field of evaporation and crystallization, in particular to an evaporation and crystallization device for treating high-salt wastewater. Background Art

[0002] Evaporation refers to the process of separating the solvent from the solute by increasing the temperature; crystallization is the process of solute polymerization into solid (crystals).

[0003] In the field of chemical product production, when evaporating and crystallizing concentrated high-salt wastewater, it is necessary to first perform evaporation treatment on it so that the high-salt wastewater changes from solid to gas for evaporation, and then cool and crystallize the gas in a special reactor through filtration. However, when cooling and crystallizing the gas, the existing evaporation device often cools the gas independently, and the cooling time is long, so it takes a long time to crystallize, which makes the gas crystallization efficiency low.

[0004] Therefore, we provide an evaporation crystallization device for treating high-salt wastewater. Utility Model Content

[0005] The purpose of this utility model is to provide an evaporation crystallization device for treating high-salt wastewater in order to improve the efficiency of evaporation crystallization in order to solve the above-mentioned technical problems.

[0006] In view of this, the utility model provides an evaporation crystallization device for treating high-salt wastewater, comprising a kettle body and a semiconductor refrigerator arranged on one side of the kettle body, wherein a plurality of sealing sleeves are fixedly installed on the upper surface of the semiconductor refrigerator, a cooling pipe is fixedly installed on the upper end of the sealing sleeve, a fixing part is fixedly installed at the pipe connection of the cooling pipe, and a cooling plate is fixedly installed on the end of the cooling pipe away from the sealing sleeve.

[0007] Preferably, a top plate is fixedly mounted on the upper end of the kettle body, a reaction box is fixedly mounted on the upper end of the top plate, the cooling plate is fixedly mounted on the surface of the reaction box, and a material removal door is hinged on the upper surface of the reaction box.

[0008] Preferably, a feed pipe is installed on one side surface of the kettle body, the feed pipe passes through the kettle body and extends into the interior thereof, and a flange is fixedly installed on one end of the feed pipe located outside the kettle body.

[0009] Preferably, a plurality of filter screens are fixedly installed inside the kettle body, a secondary filter plate is fixedly installed inside the top plate, and an electric heating plate is fixedly installed at the bottom end of the kettle body.

[0010] Preferably, an electric heater is fixedly mounted on the lower surface of the kettle body, and two quartz electric heating components are fixedly mounted on the upper surface of the electric heater, and the quartz electric heating components are mounted on the electric heating plate.

[0011] Preferably, a plurality of supporting legs are fixedly mounted on the lower surface of the kettle body, and the supporting legs are located on the outside of the electric heater.

[0012] Preferably, a heat dissipation component is fixed on one side surface of the semiconductor refrigerator.

[0013] Preferably, an electrical connection module is fixedly mounted on a surface of the semiconductor cooler on a side away from the heat dissipation component.

[0014] Compared with the prior art, the present invention provides an evaporation crystallization device for treating high-salt wastewater, which has the following beneficial effects:

[0015] 1. The utility model opens the semiconductor refrigerator on one side of the kettle body to carry out the cooling operation, and seals the connection between the cooling tube and the semiconductor refrigerator through the sealing sleeve. The generated cooling medium will be transmitted through the cooling tube. During the transmission of the cooling medium, the corner connection of the cooling tube can be made more firm by the fixing parts, so as to avoid leakage of the cooling medium during transportation. The cooling medium enters the interior of the cooling plate through the cooling tube. The cooling plates are respectively arranged on the three surfaces of the reaction box. The surface of the reaction box is surrounded by the cooling medium inside the cooling plate, so that the high-salt evaporation gas inside the reaction box is quickly cooled, and the high-salt gas inside the reaction box can be quickly cooled to form high-salt crystals, which improves the efficiency of evaporation and crystallization.

[0016] 2. In the present invention, when high-salt wastewater is heated and evaporated into gas, the filter screen filters the evaporated gas once, and filters and screens the impurities inside the evaporated gas, so that the purity of the evaporated high-salt gas is higher, and thus the overall purity of the high-salt crystals during the later crystallization is better. The secondary filter plate is set at the connection between the upper end of the top plate and the reaction box. The secondary filter plate will perform secondary filtration and screening on the gas filtered out by the filter screen to ensure the accuracy of filtration and screening. After the crystallization and cooling in the reaction box is completed, the high-salt crystals will fall onto the surface of the secondary filter plate and will not fall directly back into the reaction box, which can play a certain role as a carrier. However, the experimenter must always pay attention to the duration of the reaction crystallization, and take out the high-salt crystals in time to avoid a large amount of high-salt crystals accumulating and clogging the surface of the secondary filter plate, resulting in obstruction of gas transmission.

[0017] 3. The utility model sets an electric heater. When high-salt wastewater flows into the kettle, the electric heater is turned on to work. The heat energy generated will be conducted through the quartz electric heating component and enter the electric heating plate to heat and evaporate the high-salt wastewater liquid on its surface, achieving the effect of electric heating evaporation.

[0018] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] Example 1: An evaporation crystallization device for treating high-salt wastewater, such as Figures 1-4 As shown, it includes a kettle body 1 and a semiconductor refrigerator 8 arranged on one side of the kettle body 1. Several sealing sleeves 10 are fixedly installed on the upper surface of the semiconductor refrigerator 8. A cooling pipe 11 is fixedly installed on the upper end of the sealing sleeve 10. A fixing part 12 is fixedly installed at the pipe connection of the cooling pipe 11. A cooling plate 13 is fixedly installed on the end of the cooling pipe 11 away from the sealing sleeve 10. The semiconductor refrigerator 8 mentioned in the present invention is a prior art feature, so it is not described in detail in this embodiment. The experimenter installs the feed pipe 3 with the external storage equipment through the flange 4. The high-salt wastewater liquid required for evaporation and crystallization will enter the kettle body 1 through the feed pipe 3 to be heated and evaporated. The high-salt gas formed will enter the interior of the reaction box 5. The reaction box 5 has a good cooling effect and is convenient for transmitting the cooling medium. For transmission, the experimenters open the semiconductor refrigerator 8 on one side of the kettle body 1 to carry out the cooling operation, and seal the connection between the cooling pipe 11 and the semiconductor refrigerator 8 through the sealing sleeve 10. The generated cooling medium will be transmitted through the cooling pipe 11. During the transmission of the cooling medium, the fixing part 12 can make the corner connection of the cooling pipe 11 more secure, so as to avoid leakage of the cooling medium during transportation. The cooling medium enters the interior of the cooling plate 13 through the cooling pipe 11. The cooling plate 13 is respectively arranged on the three surfaces of the reaction box 5. The surface of the reaction box 5 is surrounded by the cooling medium inside the cooling plate 13, so that the high-salt evaporating gas inside it is quickly cooled, and then the high-salt gas inside the reaction box 5 can be quickly cooled to form high-salt crystals, which improves the efficiency of evaporation and crystallization.

[0027] like Figures 1-4 As shown, a top plate 18 is fixedly installed on the upper end of the kettle body 1, a reaction box 5 is fixedly installed on the upper end of the top plate 18, a cooling plate 13 is fixedly installed on the surface of the reaction box 5, and a material removal door 7 is hinged on the upper surface of the reaction box 5. The top plate 18 is set, which can play the role of installing a carrier, and the reaction box 5 can be installed on its upper surface. The evaporated gas inside the kettle body 1 will directly enter the interior of the reaction box 5 for cooling and crystallization after the filtration is completed. Through the set material removal door 7, after the evaporation and crystallization are completed, the experimenter can take out the high salt crystals inside by opening the material removal door 7.

[0028] like Figures 1-4As shown, a feed pipe 3 is installed on one side surface of the kettle body 1, and the feed pipe 3 passes through the kettle body 1 and extends into the interior thereof. A flange 4 is fixedly installed at one end of the feed pipe 3 located on the outside of the kettle body 1. Several filter screens 20 are fixedly installed inside the kettle body 1, and a secondary filter plate 19 is fixedly installed inside the top plate 18. An electric heating plate 16 is fixedly installed at the bottom end of the kettle body 1. When the high-salt wastewater is heated and evaporated into gas, the filter screen 20 filters the evaporated gas once, filters and screens the impurities in the evaporated gas, so that the purity of the evaporated high-salt gas is higher, thereby making the overall purity of the high-salt crystals during the later crystallization higher. The purity is even better. The secondary filter plate 19 is set at the connection between the upper end of the top plate 18 and the reaction box 5. The secondary filter plate 19 will perform secondary filtration and screening on the gas filtered out by the filter screen 20 to ensure the accuracy of filtration and screening. After the crystallization and cooling of the reaction box 5 is completed, the high-salt crystals will fall onto the surface of the secondary filter plate 19 and will not directly fall back into the interior of the reaction box 5. It can play a certain role as a carrier for objects. However, the experimenter must always pay attention to the duration of the reaction crystallization and take out the high-salt crystals in time to avoid a large amount of high-salt crystals accumulating and clogging the surface of the secondary filter plate 19, resulting in obstruction of gas transmission.

[0029] Example 2: An evaporation crystallization device for treating high-salt wastewater, such as Figures 1-4 As shown, an electric heater 14 is fixedly installed on the lower surface of the kettle body 1, and two quartz electric heating components 15 are fixedly installed on the upper surface of the electric heater 14. The quartz electric heating components 15 are installed with the electric heating plate 16. Through the arrangement of the electric heater 14, after high-salt wastewater flows into the kettle body 1, the electric heater 14 is turned on to work, and the heat energy generated will be conducted through the quartz electric heating components 15 for electric heat energy, enter the electric heating plate 16 to heat and evaporate the high-salt wastewater liquid on its surface, thereby achieving the effect of electric heating evaporation.

[0030] like Figures 1-4 As shown, a plurality of support legs 2 are fixedly installed on the lower surface of the kettle body 1, and the support legs 2 are located on the outside of the electric heater 14. A heat dissipation component 9 is fixed on one side surface of the semiconductor refrigerator 8, and an electrical connection module 17 is fixed on the side surface of the semiconductor refrigerator 8 away from the heat dissipation component 9. The support legs 2 are set, which can support the kettle body 1, so that the installation is more stable during evaporation operation. The heat dissipation component 9 is set to dissipate heat for the semiconductor refrigerator 8, avoiding the semiconductor refrigerator 8 from self-igniting due to overheating of the internal structure in a long-term working environment. Through the electrical connection module 17, it can be electrically connected to an external power source for transmission to achieve the power supply effect for the semiconductor refrigerator 8.

[0031] Working principle: The experimenter installs the feed pipe 3 with the external storage equipment through the flange 4. The high-salt wastewater liquid required for evaporation and crystallization will enter the kettle body 1 through the feed pipe 3 to be heated and evaporated. The high-salt gas formed will enter the interior of the reaction box 5. The reaction box 5 has a good cooling effect and is convenient for transmitting the cooling medium. The experimenter opens the semiconductor refrigerator 8 on one side of the kettle body 1 to carry out the cooling operation. The sealing sleeve 10 is used to seal the connection between the cooling pipe 11 and the semiconductor refrigerator 8. The generated cooling medium will be transmitted through the cooling pipe 11. During the transmission of the cooling medium, the fixing part 12 can make the corner connection of the cooling pipe 11 more firm to avoid cooling. When the medium leaks during transportation, the cooling medium enters the interior of the cooling plate 13 through the cooling pipe 11. The cooling plates 13 are respectively arranged on the three surfaces of the reaction box 5. The cooling medium inside the cooling plate 13 is surrounded by the surface of the reaction box 5 for cooling and transmission, so that the high-salt evaporated gas inside it is quickly cooled, and then the high-salt gas inside the reaction box 5 can be quickly cooled to form high-salt crystals, which improves the efficiency of evaporation and crystallization. The top plate 18 is provided, which can play the role of installing a carrier. The reaction box 5 can be installed on its upper surface. The evaporated gas inside the kettle body 1 will directly enter the interior of the reaction box 5 for cooling and crystallization after the filtration is completed. After the evaporation and crystallization are completed, the experimenter can open the material taking door 7 through the provided material taking door 7. The high-salt crystals inside it are taken out, and when the high-salt wastewater is heated and evaporated into gas, the filter screen 20 filters the evaporated gas once, and filters and screens the impurities inside the evaporated gas, so that the purity of the evaporated high-salt gas is higher, thereby making the overall purity of the high-salt crystals during the later crystallization better. The secondary filter plate 19 is set, which is set at the connection between the upper end of the top plate 18 and the reaction box 5. The secondary filter plate 19 will perform a secondary filtration and screening on the gas filtered out by the filter screen 20 to ensure the accuracy of the filtration and screening. After the crystallization and cooling of the reaction box 5 is completed, the high-salt crystals will fall to the surface of the secondary filter plate 19 and will not fall directly back into the reaction box 5, which can play a certain role as a carrier, but the experimenter must always pay attention to the reaction. The crystallization time should be calculated, and the high-salt crystals should be taken out in time to avoid a large amount of high-salt crystals accumulating and clogging the surface of the secondary filter plate 19, which will cause gas transmission to be obstructed. Through the provided electric heater 14, after high-salt wastewater flows into the kettle body 1, the electric heater 14 is turned on to work, and the heat energy generated will be conducted through the quartz electric heating component 15 to conduct electric heat energy, enter the electric heating plate 16 to heat and evaporate the high-salt wastewater liquid on its surface, and achieve the effect of electric heating evaporation. The provided support legs 2 can support the kettle body 1, making the installation more stable during the evaporation operation. The provided heat dissipation component 9 can dissipate heat for the semiconductor refrigerator 8, avoiding the semiconductor refrigerator 8 in a long-term working environment.The phenomenon of spontaneous combustion due to overheating of the internal mechanism can be electrically connected to the external power supply through the electrical connection module 17 to achieve the power supply efficiency of the semiconductor cooler 8.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
