Spray humidifier

Technical Field

The utility model belongs to the technical field of air conditioning equipment, and relates to a spraying humidifier.

Background

Air humidification is one of the basic methods for heat and humidity treatment in air conditioning engineering, and according to the heat and humidity exchange theory, the following two humidification methods are commonly used in the actual engineering:

1. the water spraying chamber sprays circulating water to humidify air, namely, the water absorbs the sensible heat of the air to perform evaporation humidification, and the change process of the humidification on an enthalpy diagram is an approximate isenthalpic process.

2. The steam is sprayed to humidify the air, namely, the air is directly sprayed into the air to humidify after water is evaporated into steam by utilizing an external heat source, and the change process of the humidification on an enthalpy-humidity diagram is an approximate isothermal process.

Steam spraying humidification requires special equipment for vaporizing water into steam, such as an electrothermal or electrode steam generator. This requires a large amount of energy consumption and a high running cost. And the water can be seriously scaled in the process of high-temperature evaporation, so that the water is used as little as possible.
