Description

Technical Field

[0001] This utility model belongs to the field of industrial wastewater treatment technology, specifically a distillation treatment device for saline industrial wastewater. Background Technology

[0002] In today's era of rapid industrial development, various industrial production activities, such as chemical processing, pharmaceutical manufacturing, printing and dyeing, and electroplating, generate large amounts of saline industrial wastewater. This wastewater has a complex composition, containing not only high concentrations of inorganic salts such as sodium chloride, sodium sulfate, and calcium chloride, but also heavy metal ions, organic matter, and other toxic and harmful substances.

[0003] Direct discharge of saline industrial wastewater without effective treatment will cause serious and multifaceted harm to the ecological environment. Firstly, the discharge of high-salinity wastewater into natural water bodies will alter the osmotic pressure, leading to dehydration of aquatic organisms, disrupting the balance of aquatic ecosystems, making it difficult for many aquatic organisms to survive, and causing a decline in biodiversity. Secondly, harmful substances such as heavy metal ions and organic matter in the wastewater may accumulate in soil and water bodies, entering the human body through the food chain and harming human health. It may also pollute the soil, affecting crop growth and soil ecological functions.

[0004] Currently, there are various methods for treating saline industrial wastewater, such as ion exchange, membrane separation, biological treatment, and distillation. While ion exchange can effectively remove certain specific ions, it suffers from high resin regeneration costs and susceptibility to fouling. Membrane separation faces challenges in treating high-salt wastewater, including severe membrane fouling, short lifespan, and high investment costs. Biological treatment methods suffer from poor treatment results because the activity of microorganisms is inhibited by the high-salt environment.

[0005] Therefore, this utility model provides a distillation treatment device for saline industrial wastewater. Utility Model Content

[0006] To overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a distillation treatment device for saline industrial wastewater is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A distillation treatment device for saline industrial wastewater, comprising a tank; a support leg is fixedly installed at the bottom of the tank, a water inlet is fixedly installed at the bottom of the tank, an air outlet is fixedly installed on one side of the top of the tank, a heating component is provided on the inner wall of the tank, a driving component is provided on the top of the tank, an adjustment mechanism is provided on the inner wall of the tank, a stirring component is provided on the inner wall of the tank, a cleaning component is provided on the inner wall of the tank, and a limiting mechanism is provided on the inner wall of the tank; the heating component includes a heat-conducting shell and a heating coil, the heat-conducting shell is fixedly installed on the inner wall of the tank, and the surface of the heat-conducting shell is fixedly installed with the heating coil; the heat-conducting shell can guide the heat generated by the heating coil into the interior and heat the wastewater inside, ensuring effective heat transfer while reducing heat loss; the heating coil can heat the exterior of the heat-conducting shell, and because it is not connected to the tank, it can prevent heat loss.

[0008] Preferably, the drive assembly includes a motor and a drive shaft. The motor is fixedly mounted on the top of the tank, and the drive shaft is rotatably mounted on the inner wall of the tank. The top end of the drive shaft is fixedly mounted to the output end of the motor. The drive shaft is located inside the heat-conducting shell. In this scheme, the combined use of the motor and the drive shaft can provide sufficient power for the use of the adjustment mechanism, the stirring assembly, and the limiting mechanism, and can make full use of the driving force of the motor, improve energy utilization, and reduce energy loss and waste.

[0009] Preferably, the adjustment mechanism includes a fixed support rod, an electric push rod, and a first bracket.

[0010] Preferably, the stirring assembly includes a stirring plate and a slot. Several sets of stirring plates are arranged and fixedly mounted longitudinally on the surface of the drive shaft. The surface of the stirring plate is provided with a slot. In this scheme, the stirring plate can stir the wastewater inside the heat-conducting shell through the drive shaft, so that the wastewater can be heated evenly, improving the heating efficiency. At the same time, it can also prevent salt in the wastewater from precipitating or adhering to the inner wall of the heat-conducting shell. The slot can reduce the contact area between the stirring plate and the wastewater, preventing excessive salt from adhering to the surface of the stirring plate.

[0011] Preferably, the cleaning assembly includes a support plate and a cleaning brush. The support plate is fixedly installed at the end of the agitator away from the drive shaft, and the side of the support plate away from the agitator is fixedly installed with the cleaning brush. In this design, the cooperation between the support plate and the cleaning brush can clean the inner wall of the heat-conducting shell, keeping the inner wall of the heat-conducting shell clean, preventing salt corrosion, and improving the service life of the heat-conducting shell.

[0012] Preferably, the limiting mechanism includes an elongated cylindrical rod, a second bracket, and a cleaning roller brush. Two sets of elongated cylindrical rods are provided, and the two sets are fixedly installed on both sides of the bottom surface of the drive shaft. The inner wall of the elongated cylindrical rod is slidably installed with the second bracket. The top of the second bracket, on the side away from the elongated cylindrical rod, is rotatably installed with the cleaning roller brush. The end of the cleaning roller brush, away from the second bracket, is rotatably installed with the first bracket. In this design, the combined use of the elongated cylindrical rod and the second bracket makes the first bracket more stable when it extends, while ensuring that the cleaning roller brush has sufficient support for use. The cleaning roller brush can cooperate with the support plate and the cleaning brush to effectively remove residual impurities that cannot be removed by the support plate.

Several sets of stirring plates 81 are arranged and fixedly installed longitudinally on the surface of the drive shaft 62. The surface of the stirring plates 81 is provided with slots 82. The cleaning assembly 9 includes a support plate 91 and a cleaning brush 92. The support plate 91 is fixedly installed at the end of the stirring plate 81 away from the drive shaft 62. The side of the support plate 91 away from the stirring plate 81 is fixedly installed with the cleaning brush 92. The limiting mechanism 10 includes an elongated round rod 101, a second bracket 102, and a cleaning roller brush 103. Two sets of elongated round rods 101 are provided. The two sets of elongated round rods 101 are fixedly installed on both sides of the bottom surface of the drive shaft 62. The inner wall of the elongated round rod 101 is slidably installed with the second bracket 102.

[0028] like Figures 1 to 6As shown, the combined use of motor 61 and drive shaft 62 provides sufficient power for the adjustment mechanism 7, stirring assembly 8, and limiting mechanism 10, fully utilizing the driving force of motor 61, improving energy efficiency, and reducing energy loss and waste.

[0029] Working Principle: During operation, first place tank 1 on a flat surface, then connect inlet 3 to a water pump and outlet 4 to a gas-liquid separator. Start the water pump to deliver wastewater to the heat-conducting shell 51, then activate heating coil 52 to generate heat. The heat-conducting shell 51 will heat up due to the heating coil 52, thus heating the wastewater inside. To accelerate the heating process, start motor 61 to drive drive shaft 62 to rotate. The rotation of drive shaft 62 will drive agitator 81 to rotate. The rotating agitator 81 agitates the wastewater inside the heat-conducting shell 51, ensuring even heating and accelerating distillation. While agitator 81 rotates, support plate 91 and cleaning brush 92 rotate synchronously, preventing salt from adhering to the wastewater. Inside the heat-conducting housing 51, the temperature of the wastewater inside continuously rises. The vaporized wastewater is discharged out through the vent 4. After distillation, the motor 61 is started to drive the drive shaft 62, support plate 91, and cleaning brush 92 to rotate, scraping off the salt adhering to the inner wall of the heat-conducting housing 51. At the same time, the electric push rod 72 is started to push the first support 73 outward. When the first support 73 extends outward, the second support 102 and cleaning roller brush 103 move synchronously until the cleaning roller brush 103 can contact the inner wall of the heat-conducting housing 51. Then, the drive shaft 62 drives the rotation to further remove the salt remaining on the inner wall of the heat-conducting housing 51, effectively preventing the salt from corroding the heat-conducting housing 51. After cleaning, the water pump is disconnected from the inlet 3, and the salt is discharged out through the inlet 3.
