mini air purifier!Working principle of wet film humidifier

　　1. General wet film humidifier

　　The water is sent to the sprinkler system through a pipeline through a water pump, and the lower part is made of a highly absorbent humidifying material - a wet film. Water permeates downwards along the wet membrane material under the action of gravity, and is absorbed by the wet membrane material to form a uniform water film; When dry air passes through wet film materials, water molecules fully absorb the heat in the air and vaporize, increasing the humidity of the air, forming moist air. The increase in humidity in the air causes a decrease in temperature, but the enthalpy value of the air remains unchanged. Wet film humidifiers are divided into two types: direct drainage humidification and circulating water humidification. The wet film direct drainage humidification system operates, and the clean tap water through the solenoid valve is sent to the water distributor at the top of the wet film through the water supply pipeline. The water flows downward along the surface of the wet film under the action of gravity, wetting the surface of the wet film. The water that flows to the water tray is discharged into the drainage pipeline through the drainage elbow, and this water is not recycled.

　　2. Circulating water wet film humidifier

　　Introduction to the working principle of a circulating water wet film humidifier, which uses clean tap water to supply the humidifier. Water enters the circulating water tank through the water supply pipeline, and its high water level is controlled by the water inlet switch. The circulating water pump sends the water in the tank to the sprinkler at the top of the humidifier, which evenly distributes the water onto the wet film material to form a uniform water film. When dry air passes through the wet film, A portion of the water surface air is vaporized and vaporized, resulting in an increase in air humidity; Another part of water that has not evaporated flows back to the water tank from the bottom of the humidifier, and the water in the circulating water tank is repeatedly recycled through the circulating water pump, achieving the goal of water conservation.
