Description

Technical Field

[0001] The invention relates to the field of production wastewater oxidation recovery, in particular to a production wastewater oxidation recovery device. Background Art

[0002] In the dye processing and production industry, 2% of the products for every ton of dye produced are discharged with wastewater, which not only causes a large loss of dyes, but also brings huge economic losses and leads to environmental pollution. There are tens of thousands of types of dyes, which have complex structures, are difficult to degrade and have low biodegradability. They are extremely toxic, either explicitly or potentially. Once they are discharged directly into the water without treatment, they will cause obvious damage to the microbial environment of the water and the soil, and thus endanger the human living environment. Faced with such an urgent situation, coupled with the guidance of energy-saving and emission reduction policies, how to efficiently and cleanly dispose of them? The wastewater contains cyanide, which is difficult to treat. The production process produces a large amount of cyanide-containing washing mother liquor during centrifugal washing of the bromide solution. It has the characteristics of complex components, high chroma, high COD and BOD concentrations, many suspended solids, large changes in water quality and water volume, and many difficult-to-degrade substances. It is one of the more difficult to treat industrial wastewaters.

[0003] The treatment method for washing mother liquor containing cyanide is generally to thermally oxidize hydrogen bromide in the mother liquor into elemental bromine, and the elemental bromine is returned to the bromination process to further participate in the reaction, which reduces the discharge of wastewater, realizes the recycling of dye intermediate wastewater, and improves the product yield and reduces the production cost. At present, hydrogen bromide is thermally oxidized into elemental bromine, and hydrogen peroxide is usually selected as an oxidant. Hydrogen peroxide reacts with hydrogen bromide under acidic conditions to generate water and elemental bromine. The oxidized reaction liquid is then distilled, and the bromine is distilled out by utilizing the low boiling point of bromine. When hydrogen peroxide is mixed with hydrogen bromide for reaction, the mixing degree of the two needs to be ensured so that more elemental bromine can be produced and the subsequent distillation effect can be achieved. The current distillation equipment is limited to being a container for containing solutions due to its structural design. There is still room for expansion for the mixing of multiple materials.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Reference Figure 1 - Figure 8 , a production wastewater oxidation recovery device, comprising an evaporation box 1, an evaporation component is provided in the evaporation box 1, and a condensation component is provided at the upper port of the evaporation box 1; The evaporation assembly includes a rotating shaft 2, which is horizontally arranged in the evaporation box 1, and a wheel body 3 is coaxially fixedly connected to the middle position of the rotating shaft 2, and a plurality of arc-shaped evaporation plates 4 are arranged on the surface of the wheel body 3; The condensation assembly includes a cover plate 5 covering the upper port of the evaporation box 1, and a material pipe 6 is connected to the cover plate 5. The end of the material pipe 6 extends downwardly at an angle, and the inclined portion of the material pipe 6 is a condensation pipe 7. The water inlet end of the outer pipe 8 of the condensation pipe 7 extends downward, and the water outlet end of the outer pipe 8 of the condensation pipe 7 extends upward. The inlet end of the inner pipe 9 of the condensation pipe 7 is expanded and connected to the upper port of the evaporation box 1; In this embodiment, the end of the rotating shaft 2 is connected to an external driving device, such as a motor that can drive the rotating shaft 2 to rotate forward and reverse; a feed port is set at the upper end of the evaporation box 1 for feeding hydrogen bromide wastewater and oxidant hydrogen peroxide, and the feed port is in a normally closed state; the bottom of the evaporation box 1 is set in an arc shape and is designed to match the outer contour of the wheel body 3, and a discharge port is also set at the bottom of the evaporation box 1 for discharging the waste material of the later distillation; a plurality of evaporation plates 4 on the wheel body 3 are connected to the power supply through the wheel body 3, and the evaporation plates 4 are used to evaporate the bromine solution, that is, the bromine solution generated by the hydrogen bromide wastewater and the oxidant hydrogen peroxide; the material pipe 6 is set to keep the condenser 7 and the bromine vapor warm, so as to reduce the temperature interference of the external environment on the bromine vapor; The hydrogen bromide wastewater and the oxidant hydrogen peroxide are filled into the evaporation box 1 to form a mixed liquid, and then the motor is driven to drive the wheel body 3 to rotate through the rotating shaft 2; During the slow rotation of the wheel body 3, the wheel body 3 can stir the mixed liquid in the evaporation box 1 to ensure that the oxidant is fully in contact with the wastewater, thereby improving the oxidation reaction efficiency of hydrogen bromide and hydrogen peroxide. At the same time, after the evaporation plate 4 rotates out of the mixed liquid, the mixed liquid dipped on the evaporation plate 4 is heated and evaporated by the evaporation plate 4, and separated by using the difference in boiling points of water and bromine. The boiling point of water is 100°C, and the boiling point of bromine is 58.8°C. By controlling the current passed through the evaporation plate 4, the temperature of the evaporation plate 4 is controlled, so that the mixed liquid dipped on the evaporation plate 4 is heated to 60°C-80°C, and the elemental bromine solution evaporates and flows into the material pipe 6 along the upper port of the evaporation box 1, and then flows into the condenser 7. Cooling water is continuously passed into the outer tube 8 of the condenser 7 to cool the vaporized elemental bromine, and the cooled elemental bromine liquid is finally discharged from the lower end of the inner tube 9 of the condenser 7 for centralized recovery; In this embodiment, the wheel body 3 is designed to stir the hydrogen bromide wastewater and the oxidant hydrogen peroxide during rotation, and the stirring is continuous, which can ensure that the oxidant is in full contact with the wastewater and improve the oxidation reaction efficiency of hydrogen bromide and hydrogen peroxide. At the same time, the wheel body 3 is continuously rotated to continuously rotate each evaporation plate 4 out of the mixed liquid. After being taken out, the evaporation plate 4 can quickly heat and evaporate the elemental bromine solution on the evaporation plate 4, and the evaporation effect is also significantly improved.

[0022] Reference Figure 1 - Fig.12 A conductive component is provided between the two sides of the wheel body 3 and the inner wall of the evaporation box 1. The conductive component is used to transmit current to the evaporation plate 4, and the conductive component includes a ring body 10. The inside of the ring body 10 is hollow. One end face of the ring body 10 is fixedly connected to the inner wall of the evaporation box 1 through a plurality of insulating rods 11. The end faces of the ring body 10 opposite to the wheel body 3 are open, and a plurality of conductive rods 12 are provided in the open mouth of the ring body 10. One end of the conductive rod 12 is attached to the inner surface of the outer ring plate of the ring body 10 to slide, and the other end of the conductive rod 12 is fixedly connected to the side wall of the wheel body 3. Two conductive rods 12 on opposite sides of the wheel body 3 are electrically connected to an evaporation plate 4; The setting of the conductive component independently supplies stable power to the evaporation plate 4, while reducing the possibility of short circuit of the recovery device as a whole; the ring body 10 is fixed to the evaporation box 1 through the insulating rod 11, and the entire ring body 10 is erected in the evaporation plate 4, and can be electrically connected to the external power supply through a wire. The ring bodies 10 on both sides of the wheel body 3 are connected to the positive pole of the power supply and the negative pole of the power supply. One end of the conductive rod 12 slides along the inner surface of the outer ring plate of the ring body 10. At this time, the evaporation plate 4 is electrically connected to the ring body 10 through the conductive rod 12, that is, the evaporation The generator plate 4 is electrically connected to the positive and negative electrodes of the power supply; the conductive rod 12 is arranged close to the axis of the wheel body 3, the liquid level of the mixed liquid in the evaporation box 1 is lower than the height of the conductive rod 12, and the ring body 10 is also located above the liquid level of the mixed liquid. Even if the wheel body 3 rotates and stirs the mixed liquid, the swing of the mixed liquid cannot contact the conductive rod 12 and the ring body 10, thereby reducing the possibility of an overall short circuit in the recovery device. At the same time, one end of the conductive rod 12 slides along the inner surface of the outer ring plate of the ring body 10, which can provide stable power for the evaporation plate 4.

[0023] Reference Figure 1 - Fig.12 , the inner surface of the lower half of the outer ring plate of the ring body 10 is arranged away from one end of the conductive rod 12; like Fig.10 As shown, the outer ring plate of the ring body 10 is protruded downward. When the conductive rod 12 rotates relatively to the lower half of the ring body 10, one end of the conductive rod 12 is no longer in contact with the ring body 10. At this time, the upper half of the outer ring plate of the ring body 10 is in electrical contact with the conductive rod 12, which controls the evaporation plate 4 rotating out of the mixed liquid to pass current, that is, the evaporation plate 4 rotating out of the mixed liquid has the function of heating and evaporating the elemental bromine solution. This design saves power by controlling a single or multiple evaporation plates 4 to be energized instead of all evaporation plates 4, thereby saving power resources. Secondly, it avoids continuous heating of the mixed liquid. When the mixed liquid is heated to nearly 100°C, part of the water will evaporate and mix with the bromine vapor, affecting the extraction and recovery quality of the elemental bromine solution.

[0024] Reference Figure 1 - Figure 7 A plurality of strip grooves 13 are evenly formed on the outer surface of each evaporation plate 4. The strip grooves 13 are formed along the two sides of the wheel body 3. Drainage grooves 14 are also formed on the two sides of each evaporation plate 4. The drainage grooves 14 overlap with the two sides of the strip grooves 13. The strip grooves 13 are arranged to increase the surface area of ​​the evaporation plate 4, contact more mixed liquid, and further improve the evaporation efficiency of the elemental bromine solution. At the same time, when the strip grooves 13 are placed in the mixed liquid, the resistance to the mixed liquid is increased, and the rotating wheel body 3 can further stir the mixed liquid; The drainage groove 14 is provided to guide the flow path of the mixed liquid in the strip groove 13 to prevent the mixed liquid from dripping onto the ring body 10 or the conductive rod 12 and causing corrosion to the ring body 10 or the conductive rod 12 .

[0025] Reference Figure 1 - Fig.12 The other end of each conductive rod 12 is connected to the side wall of the wheel body 3 through a spring 15, and one end of the conductive rod 12 is inclined and arranged away from the axis of the wheel body 3; The conductive rod 12 is connected to the wheel body 3 through a spring 15, and the spring 15 is electrically connected to the evaporation plate 4. By utilizing the elasticity of the spring 15, one end of the conductive rod 12 can continuously squeeze the inner surface of the upper half of the outer ring plate of the ring body 10 in an inclined state, which is also a way to improve the electrical stability connection between the conductive rod 12 and the ring body 10. Even if one end of the conductive rod 12 and the ring body 10 rotate, rub and wear, the elasticity of the spring 15 can ensure the stability of the electrical connection between the conductive rod 12 and the ring body 10.

[0026] Reference Figure 1 - Figure 8 A cover plate 16 is provided inside the upper port of the evaporation box 1, the upper edge of the cover plate 16 is fixed to the cover plate 5, the lower edge of the cover plate 16 is arranged in an arc shape, and the lower edge of the cover plate 16 is arranged close to the surface of the evaporation plate 4; The lower edge of the cover plate 16 is arranged close to the evaporation plate 4. After the bromine vapor is generated on the evaporation plate 4, the flow of the bromine vapor is guided so that the bromine vapor can fully flow along the material pipe 6 into the condenser tube 7, thereby reducing the amount of bromine vapor flowing out into the evaporation box 1 and improving the evaporation extraction and recovery efficiency of the elemental bromine solution.

[0027] Reference Figure 1 - Figure 5 A roller brush 17 is provided on one side of the cover plate 16, and both ends of the roller brush 17 are rotatably connected to the evaporator box 1, and the end of the roller brush 17 is connected to the end of the rotating shaft 2 through a belt; Pulleys are provided at the ends of the roller brush 17 and the ends of the rotating shaft 2, and the two pulleys are connected by a belt drive. When the wheel body 3 rotates, the roller brush 17 is also driven to rotate. The rotation of the roller brush 17 can clean the foreign matter on the evaporation plate 4, and some foreign matter attached to the evaporation plate 4 can be cleaned and loosened. When the evaporation plate 4 rotates again, it can directly contact the mixed liquid, thereby ensuring the heating and evaporation effect of the evaporation plate 4 on the elemental bromine solution. The rotation of the roller brush 17 rotates with the rotation of the wheel body 3, and no additional power source is required to drive the roller brush 17 to rotate.

[0028] Reference Figure 1 - Fig.12 One end of the conductive rod 12 is rotatably connected to a ring-shaped conductor 20, which is attached to the inner surface of the upper half of the outer ring of the ring body 10 and rolls; A conductor 20 is arranged at one end of the conductive rod 12. The conductor 20 can be attached to the inner surface of the upper half of the outer ring enclosure of the ring body 10 and roll, thereby converting the sliding friction between the conductive rod 12 and the ring body 10 into rolling friction between the conductor 20 and the ring body 10, thereby reducing wear. At the same time, a brush can be arranged on the outer surface of the inner ring enclosure of the ring body 10, and the brush can contact the surface of the conductor 20. During the rotation of the conductor 20, the brush cleans the surface of the conductor 20, removes foreign matter or wear debris on the surface of the conductor 20, and ensures a good electrical connection between the conductive rod 12 and the ring body 10.

[0029] Reference Figure 1 - Figure 7 , annular baffles 18 are provided on both side edges of the wheel body 3; The baffle plate 18 is used to assist the guide groove in limiting the flow of the mixed liquid. The baffle plate 18 can shield the mixed liquid to prevent the mixed liquid on the surface of the evaporation plate 4 above from dripping onto the conductive rod 12 or the ring body 10 .

[0030] Reference Figure 1 - Fig.13 The inner tube 9 of the condenser tube 7 is provided with a plurality of vortex-shaped tube bodies 19, and the plurality of tube bodies 19 are connected end to end in sequence; The surface of the inner tube 9 of the condenser 7 is provided with a multi-vortex tube body 19, so that the bromine vapor can flow along the tube body 19, and the setting of the tube body 19 can extend the cooling path and duration of the bromine vapor. Even if more bromine vapor is generated, the condenser 7 can fully cool the bromine vapor into a single bromine solution.

[0031] Working principle: hydrogen bromide wastewater and oxidant hydrogen peroxide are filled into the evaporation box 1 to form a mixed liquid, and then the motor is driven, and the motor drives the wheel body 3 to rotate through the rotating shaft 2; during the slow rotation of the wheel body 3, the wheel body 3 can stir the mixed liquid in the evaporation box 1 to ensure that the oxidant and the wastewater are fully in contact, thereby improving the oxidation reaction efficiency of hydrogen bromide and hydrogen peroxide. At the same time, after the evaporation plate 4 rotates out of the mixed liquid, the mixed liquid dipped on the evaporation plate 4 is heated and evaporated by the evaporation plate 4, and the boiling point difference between water and bromine is used for separation. The boiling point of water is 100°C, while the boiling point of bromine is 58.8°C. By controlling the current passed through the evaporation plate 4, the temperature of the evaporation plate 4 is controlled, so that the mixed liquid dipped on the evaporation plate 4 is heated to 60°C-80°C, and the elemental bromine solution evaporates and flows into the material pipe 6 along the upper port of the evaporation box 1, and then flows into the condenser 7. Cooling water is continuously passed into the outer tube 8 of the condenser 7 to cool the vaporized elemental bromine, and the elemental bromine is cooled to become elemental bromine liquid, and finally flows out from the lower end of the inner tube 9 of the condenser 7 for centralized recovery.
