Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings.
[0019] as attached figure 1 and 2 As shown, the solution dehumidification device based on ultrasonic atomization and electrostatic hydrophobicity includes an ultrasonic atomization solution unit A, a gas-liquid heat mass transfer unit B, an impact defogging unit C and a high-voltage electrostatic demisting unit D arranged in sequence. The inlet of the ultrasonic atomization solution unit A is connected to the humid air pipeline through a variable diameter and a branch pipe, and the humid air enters from the inlet of the ultrasonic atomization solution unit A, and passes through the gas-liquid heat mass transfer unit B, the impact defogging unit C and the high-voltage electrostatic Demister unit D, the last thing that comes out is dry air.
[0020] The ultrasonic atomized solution unit A is a box with a cubic structure, and a concentrated solution storage tank 7 is ar...

The invention discloses a liquid dehumidification device based on ultrasonic atomization and electrostatic hydrophobic. The liquid dehumidification device comprises an ultrasonic atomizing solution unit, a gas-liquid heat mass transferring unit, a hitting demisting unit and a high-voltage electrostatic demisting unit which are connected in sequence; humid air enters from the ultrasonic atomizing solution unit and finally comes out to be dry air after passing the gas-liquid heat mass transferring unit, the hitting demisting unit and the high-voltage electrostatic demisting unit. Compared with a traditional packed-tower dehumidification device, the liquid dehumidification device has the advantages of large gas-liquid contact areas, the problem that droplet entrainment existing in ultrasonic atomization liquid dehumidification cannot be removed completely is solved, and heat and mass transfer performance of the dehumidification device is improved under the condition that the droplet entrainment is not increased.
Description
technical field [0001] The invention belongs to the technical field of air dehumidification and independent treatment of heat and humidity, and in particular relates to a solution dehumidification device based on ultrasonic atomization and electrostatic hydrophobicity. Background technique [0002] Traditional air-conditioning systems generally generate 7-12°C cold water through an artificial cold source-refrigeration unit, which is passed into the air handling unit, and then generates low-temperature and dry air to be sent to the room to uniformly control the temperature and humidity of the room. In this way, more than 50% of the sensible heat load that can be treated with high-temperature cold water (16-18°C) must also be taken away by low-temperature cold water. The COP of the chiller is low and the power consumption is large. At the same time, because the air supply is close to the saturation line in the condensation dehumidification mode, the range of heat-humidity rati...
