Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature vacuum evaporators for hazardous waste water, in particular to a low-temperature vacuum evaporator for hazardous waste water. Background Art

[0002] The main function of the low-temperature vacuum heat pump evaporator is to lower the boiling point of the raw liquid under vacuum pressure, causing it to boil and evaporate at over 30 degrees Celsius after heating. This prevents harmful substances in hazardous wastewater from boiling at high temperatures, ensuring the stability and compliance of recycled water quality. The evaporated steam is condensed into liquid water through the condensation system and discharged through the drain pipe. Depending on the specific gravity of the water, the concentration and reduction rate can reach up to 95%;

[0003] However, after use, the existing low-temperature vacuum evaporator for hazardous waste water will produce a large amount of recycled water and a portion of high-concentration concentrated waste liquid. Since the water content in these concentrated waste liquids is low, the fluidity of these concentrated waste liquids is low, and the concentrated waste liquids become viscous, causing these concentrated waste liquids to be easily adsorbed inside the distillation tank in the low-temperature vacuum evaporator for hazardous waste water, causing the concentrated waste liquids to easily remain in the distillation tank, causing great trouble to the cleaning of the distillation tank; therefore, it does not meet the existing needs, and we have proposed a low-temperature vacuum evaporator for hazardous waste water.

The lower end of the flexible spring 13 is fixedly installed with the shock ball 14;

[0027] The waste discharge rod 15 is welded to one side of the lower end surface of the rotating bracket 10. A cleaning bracket 16 is welded to one side of the waste discharge rod 15. A spiral bracket 17 is installed at the lower end of the waste discharge rod 15. The spiral bracket 17 can be installed to rotate, so that the spiral bracket 17 pushes the concentrated waste liquid to move, thereby making the concentrated waste liquid better discharged from the device, ensuring that the device discharges the concentrated waste liquid smoothly. The spiral bracket 17 is fixedly connected to the waste discharge rod 15, and a driven gear 11 is fixedly installed on the upper end of the rotating bracket 10. A driving gear shaft 12 is provided on one side of the driven gear 11. The driving gear shaft 12 is rotatably connected to the main body 1 of the hazardous waste water low-temperature vacuum evaporator distillation tank through a bearing, and the driving gear shaft 12 is meshed with the driven gear 11.

[0028] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4A driving motor 7 is fixedly installed on one side of the upper end surface of the main body 1 of the hazardous waste water low-temperature vacuum evaporator distillation tank, and the driving motor 7 is connected to the driving gear shaft 12 through a coupling. A hazardous waste water discharge pipe 5 is installed on the other side of the upper end surface of the main body 1 of the hazardous waste water low-temperature vacuum evaporator distillation tank, and the hazardous waste water discharge pipe 5 is fixedly connected to the main body 1 of the hazardous waste water low-temperature vacuum evaporator distillation tank. A concentrated liquid discharge pipe 3 is installed at the lower end of the main body 1 of the hazardous waste water low-temperature vacuum evaporator distillation tank, and the concentrated liquid discharge pipe 3 is fixedly connected to the main body 1 of the hazardous waste water low-temperature vacuum evaporator distillation tank. A heat exchange pipe 4 is arranged inside the heat conductive layer 8, and the heat exchange pipe 4 is connected to the heat conductive layer 8 is connected through a card slot, and a vacuum pipe 18 is installed at the rear end of the upper end surface of the main body 1 of the low-temperature vacuum evaporator for hazardous waste water. The vacuum pipe 18 is welded to the main body 1 of the low-temperature vacuum evaporator for hazardous waste water. The main body 1 of the low-temperature vacuum evaporator for hazardous waste water is fixedly connected to the heat-conducting layer 8. The installation of the limit platform 9 can ensure that the rotating bracket 10 can rotate stably and ensure the stable operation of the device.

Then the staff will discharge the hazardous waste water into the pipe 5 through the hazardous waste water and add it to the inside of the hazardous waste water low temperature vacuum evaporator distillation tank body 1. Then the vacuum pump will draw the vacuum degree inside the hazardous waste water low temperature vacuum evaporator distillation tank body 1 to -0.096MPa. Then the heat exchange mechanism will pass the heat exchange medium into the heat exchange pipe 4 to increase the temperature inside the heat exchange pipe 4. Since the air pressure of the hazardous waste water low temperature vacuum evaporator distillation tank body 1 is low, the boiling point of the water in the hazardous waste water is reduced. When the water heats up, it evaporates to form water vapor. The water vapor passes through the regeneration The water vapor discharge pipe 6 enters the condensation tank and condenses into recycled water, and the concentrated waste liquid finally formed is discharged from the device through the concentrated liquid discharge pipe 3. When the concentrated liquid is discharged from the concentrated liquid discharge pipe 3, the driving motor 7 drives the driving gear shaft 12 to rotate, so that the driving gear shaft 12 drives the rotating bracket 10 to rotate through the driven gear 11, so that the waste discharge rod 15 and the cleaning bracket 16 at the lower end of the rotating bracket 10 rotate, so that the cleaning bracket 16 scrapes the concentrated waste liquid remaining inside the device. When the cleaning bracket 16 rotates, the cleaning bracket 16 collides with the oscillation ball 14 at the lower end of the limit platform 9, causing the cleaning bracket 16 to vibrate, and the vibration is transmitted to the concentrated waste liquid scraped off by the cleaning bracket 16, so that the concentrated waste liquid is better and faster discharged downward from the device, preventing the concentrated waste liquid from remaining inside the distillation tank body 1 of the hazardous waste water low-temperature vacuum evaporator, and reducing the difficulty of cleaning the device.
