Description

Technical Field

[0001] This utility model relates to the field of air humidification equipment, and in particular to a wet film humidifier with wastewater discharge and overflow prevention functions. Background Technology

[0002] A wet film humidifier is a clean and energy-efficient new type of humidification equipment. It features a simple structure, no special requirements for water quality, and no white powder residue when humidifying air. It is widely used in computer rooms, paper mills, tobacco processing workshops, offices, and modern residences. Wet film humidification is an isenthalpic humidification method. Its main component is a wet film, which is a corrugated, cross-linked, overlapping hydrophilic material bonded with special components, providing a large contact area between air and water. The humidification capacity of a wet film humidifier is directly related to the airflow and the evaporation surface area of ​​the wet film.

[0003] In existing wet film humidifiers, water is typically supplied from a water tank to the wet film humidification assembly to humidify and purify the air. The humidified water then returns to the water tank, forming a water cycle. However, the humidified water often contains impurities from the dry, turbid air, making it no longer clear. Continuing to use this turbid water to purify the air affects the quality of the exhaust air, thus posing a threat to human health. At the same time, the water level in the tank needs to be constantly monitored manually, as excessive water often overflows, damaging the internal structural components. Utility Model Content

[0024] The wet film humidification unit 4 includes a wet film humidifier assembly 15 for spraying water and humidifying the air. The water circulation pipeline structure includes a water spraying pipe 16 arranged on the top of the wet film humidifier assembly 15. A cavity 17 is provided between the wet film humidifier assembly 15 and the air inlet 2. Specifically, the water spraying pipe 16 extends outward to the cavity 17 and is provided with a connecting pipe 26. A water passage pipe 27 is provided at the bottom of the cavity 17. The water circulation pipeline structure connects the water pump 11 and the connecting pipe 26 through the water passage pipe 27.

[0025] The water in the water tank 6 is fed into the water spray pipe 16 through the water circulation pipe structure. The water spray pipe 16 sprays the water onto the wet film humidifier assembly 15. The water sprays into the wet film humidifier assembly 15 and purifies the turbid air. The wastewater containing the turbid matter in the air is finally returned to the water tank 6 through the return water port 18.

[0026] The air inlet 2 includes a filter plate 19 located on the side of the main unit 1. The filter plate 19 has air inlets 20 evenly distributed on it for air intake.

[0029] The specific structure and working principle of the wet film humidifier assembly 15 are common and easily conceived techniques for those skilled in the art, so they will not be elaborated upon further.

[0030] The working principle of this utility model is as follows: An external water source is connected to the water inlet pipe structure 7. Water enters the water tank 6 from the water inlet on the side wall of the water tank 6 through the water inlet pipe structure 7. The water in the water tank 6 is pumped into the wet film humidification section 4 by the water pump 11. The water enters the water spray pipe 16 through the water circulation pipe structure connecting the water pump 11 and the pipe 26, and then exits through the water spray pipe 16 at the top of the wet film humidifier assembly 15. External air enters the machine body through the air inlet 20 on the filter plate 19. The dry and turbid air after the initial filtration by the filter plate 19 and the air inlet 20 enters the cavity 17 and then enters the wet film humidifier. Inside the assembly 15, water sprayed from the water pipe 16 humidifies and purifies the air within the wet film humidifier assembly 15. The purified water carries away impurities and dust from the air, forming wastewater. The wastewater is discharged through the return water port 18 at the bottom of the wet film humidifier assembly 15 and then returns to the water tank 6 through the water circulation pipe structure. Therefore, the water in the water tank 6 gradually becomes turbid due to the introduction of wastewater. At the same time, the air humidified and purified inside the wet film humidifier assembly 15 enters the air outlet 3 and is blown out to the air outlet frame 22 by the air outlet fan 21, and finally blown out to the outside through the air outlet grille 23, resulting in humidified and clean air. After a period of use, the water in the water tank 6 becomes so turbid that it is no longer suitable for circulating and humidifying the air. In this case, the wastewater is discharged to the outside through the drain outlet 12 at the bottom of the water tank 6, through the wastewater pipe 9, the three-way valve 10, and the outlet pipe 14. Fresh water is then introduced through the inlet pipe structure 7 to carry out the next water circulation and humidification operation. At the same time, as fresh water is introduced into the water tank 6, the water level in the water tank 6 gradually rises. When the water level rises to the overflow outlet 13 located on the side wall of the water tank 6 near the top, in order to prevent overflow and damage to the internal structural parts of the main unit 1, the water is discharged from the overflow outlet 13. The water discharged from the overflow outlet 13 is discharged to the outside through the overflow pipe 8, the three-way valve 10, and the outlet pipe 14.

[0031] The advantages of this utility model are: by setting an inlet pipe structure 7 and a drain pipe structure on the water tank 6, the drain pipe structure includes an overflow pipe 8 and a wastewater discharge pipe 9. The wastewater discharge pipe 9 is used to discharge the turbid wastewater containing impurities after the air has been purified in the water tank 6, so as to keep the water source clean. The overflow pipe 8 is used to prevent the water in the water tank 6 from overflowing due to excessive water, which could damage other parts inside the host 1.
