Description

Technical Field

[0001] The utility model relates to the technical field of evaporator equipment, in particular to a water evaporator. Background Art

[0002] The low-temperature vacuum evaporator is evacuated into a vacuum state by a vacuum pump. The vacuum degree of the evaporation chamber is about 95%~97%. The boiling point of water is 35 degrees Celsius~37 degrees Celsius at this pressure. The system does not need to be equipped with a feed pump. The negative pressure of the evaporation chamber is used to suck the material into the evaporation chamber, and the material is circulated and atomized by a forced circulation pump and sprayed onto the heat exchanger. The moisture in the material is evaporated, and the material is continuously circulated and atomized. The material is automatically replenished through the liquid level in the evaporation chamber. When the concentration reaches the requirement, it is discharged from the equipment as a concentrated liquid.

[0003] Therefore, the current evaporation structure mainly sprays the material onto the heat exchanger, the water in the material is evaporated, and the material is continuously circulated and atomized for evaporation. However, with the development of people's processing and manufacturing industries, the demand for wastewater treatment is gradually increasing, and more and more wastewater needs to be treated. Only this structure can no longer meet the demand and cannot keep up with the treatment efficiency. In addition, heat exchange evaporation also requires a heating component, and the power demand is relatively large. Therefore, an improved technology that can improve evaporation efficiency and save energy is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0025] The water evaporation filler assembly 3 includes a plurality of truncated cone-shaped support bodies 9, which are also shaped like other structures with the largest surface area, such as a pyramid shape, with the smaller end facing upwards, and a mounting edge 10 tightly mounted in the tank body 1 is provided on the side of the support body 9. The support bodies 9 are arranged side by side up and down, and the shortest distance between each other can be taken. The support body 9 is hollow inside, and the number of support bodies 9 is set according to the use requirements. The outer side of the support body 9 is provided with a plurality of stepped table surfaces 11, and the table surface 11 is provided along the circumferential direction. A number of leakage holes 12 are evenly distributed, and a number of contact fillers 13 are provided on each table 11 and along the circumference. The contact fillers 13 are preferably ball rings. The contact fillers 13 are located above the leakage holes 12 and allow liquid to flow from the contact fillers 13 into the leakage holes 12. The coordinated design of the support body 9 and the ball ring allows water mist to fall onto its outer surface to form a thin oil film, greatly increasing the surface area, so that water can evaporate easily and be sucked away by the vacuum equipment through the vacuum pipe 6, thereby making the treatment of oily wastewater more efficient and convenient.

[0026] A lifting lug 14 is installed on the upper head 4. At least two lifting lugs 14 are installed for lifting the tank body 1. A tank body fixing piece 15 is provided on the outer side of the tank body 1 for easy installation.

[0027] As an embodiment of the utility model, in addition to the above structure, the water mist spray assembly 2 includes a three-claw nozzle 16, and can also be a nozzle with a greater number of claws. The spraying end of the three-claw nozzle 16 is equipped with an impact-type atomizing nozzle 17. The impact-type atomizing nozzle 17 can disperse the liquid into tiny droplets in an instant, and can control the size and dispersion of the droplets, thereby improving the atomization efficiency. The liquid inlet end of the three-claw nozzle 16 is connected to a liquid inlet pipe 18 through a pipe connector. The liquid inlet pipe 18 enters from the bottom end of the tank body 1 and then extends to the upper end of the tank body 1, and is finally connected to the three-claw nozzle 16. One end of the liquid inlet pipe 18 located outside the tank body 1 is connected to an external wastewater source.

[0028] As an embodiment of the utility model, in addition to the above-mentioned structure, it also includes a liquid level detection component for detecting the liquid level in the tank body 1. The liquid level detection component includes a float liquid level gauge 19 located in the tank body 1, a valve body 20 and a liquid level installation pipe 21 located outside the tank body 1.

[0030] When the utility model is implemented:

[0031] The liquid inlet pipe draws the wastewater into the tank body and sprays it through the impact atomizing nozzle. The impact atomizing nozzle instantly disperses the liquid into tiny droplets and drops them onto the outer or inner surface of the support body and the ball ring, spreading the liquid to increase the surface area, increasing the surface area of ​​contact between the liquid and the gas, thereby accelerating the air flow rate on the liquid surface, quickly evaporating the water, and the vacuum equipment draws the water away, leaving waste oil and / or impurities, which finally accumulate in the tank body and are sucked away and discharged by the oil pump.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
