> Comparison between direct drainage wet film humidifiers and circulating water wet film humidifiers
> Principle of direct drainage wet film humidifiers The water in the water tank is transported to the sprinkler on the top of the humidifier, and the water is evenly poured onto the wet film At the top, the sprinkler ensures that water is evenly distributed on the wet film material. The water penetrates downward along the wet film material under the action of gravity, wets all layers inside the wet film, and is absorbed by the wet film material at the same time, forming a uniform water film. When the dry wind passes through the wet film material, the dry air and the moist wet film surface have a large area of contact, and the water fully absorbs the heat of the air and vaporizes and evaporates, thereby achieving the purpose of humidifying the air. During this humidification process, the humidity of the air increases and the temperature decreases, but the enthalpy of the air remains unchanged.
> The principle of circulating water wet film humidifier is to use wet film materials for humidification, which belongs to isenthalpy clean humidification. Its working process is that clean tap water enters the circulating water tank through the water inlet pipe, and the water level is controlled through the float valve when the humidifier is working. , the circulating water pump transports the water in the water tank to the sprinkler on the top of the humidifier. The sprinkler ensures that the water is evenly distributed to the wet film material. The water penetrates downward from the top of the wet film material and is absorbed by the wet film material to form a uniform of water film. When the dry air passes through the humidifier, part of the water vaporizes and evaporates in contact with the air, making the air moist (that is, the humidity increases) to achieve the purpose of humidification. The water that has not evaporated flows back to the circulating water tank from the lower part of the humidifier, and the water in the circulating water tank passes through the cycle. The water pump is recycled repeatedly. When the water level in the circulating water tank drops, the water inlet switch is turned on to replenish the water tank to ensure that the water level in the water tank is maintained within the set height range. When the water level in the circulating water tank drops to a certain height, the low water level sensor in the water tank works. , ensure that the circulating water pump stops running when there is a lack of water. When the water in the circulating water tank circulates for a certain period of time, the water is discharged through the drain port of the water tank, the water tank is cleaned, and clean water is replaced to ensure that the circulating water and humidified air are not polluted again.

> The core of the wet film humidifier is the wet film material. It uses plant fiber as the base material and is treated with resin with special ingredients and sintered to form a corrugated plate-shaped cross-overlapping polymer composite material. It has strong water absorption, good self-cleaning ability, non-toxic, acid and alkali resistance, mold resistance, flame retardant and provides the largest contact surface area between moisture and air. The structure of the wet membrane can provide the largest contact area between the air and its surface. Each square meter of membrane body can provide a contact area of
~
m2. The inclination angle of the membrane flow channel is
degrees.
At present, there are four materials for wet film humidifiers, organic wet film, inorganic glass fiber wet film, metal aluminum alloy wet film, and metal stainless steel wet film.
