Embodiment
[0073] Such as figure 1 As shown, the present invention is suitable for treating highly concentrated saline wastewater. The waste water will be split into all evaporation parts 2 of the humidification dehumidification system with three evaporation / condensation units 1 . The waste water is distributed on the filling material 7 through the distribution tank 6 and evaporates at a rate corresponding to the flow rate of the carrier gas mixture and the temperature inside the evaporation part 2, and the flowing carrier gas mixture will carry away part of the evaporated water from the waste water. Waste water is collected at the bottom of the evaporator element 2 and fed back into the waste water circuit 11 . Evaporation of the water results in a higher concentration of wastewater leaving the evaporating part 2 than entering the evaporating part 2, and the carrier gas mixture leaving the evaporating part 2 contains more water vapor and has a higher concentration than the carrier gas ...

The invention discloses a humidification-dehumidification system and a distillation method using same, relates to the technical field of distillation, and aims to solve the problem that a conventional humidification-dehumidification system is low in heat exchange efficiency. The humidification-dehumidification system comprises a plurality of evaporation / condensation units, wherein each evaporation / condensation unit comprises an evaporation member; each evaporation member comprises a fluid circulation system and an evaporation chamber; at least one of the evaporation / condensation unit further comprises a condensation member; the condensation members comprise condensation chambers; each condensation member is supplied with a recycling heat exchanger, at least one heat source and at least one cold source. Due to adoption of the evaporation / condensation units, a gas-carrying mixture can be enabled to flow through all evaporation members in a preset unit sequence, and flow through all condensation members in a unit sequence opposite to the preset unit sequence; each evaporation / condensation unit has independent control on the circulation system of the evaporation member in the evaporation / condensation unit, and thus the flowing speed of liquid-containing fluid in each evaporation member can be independently adjusted.
Description
technical field [0001] The invention relates to the technical field of distillation, in particular to a humidification and dehumidification system and a distillation method using the same. Background technique [0002] Evaporation is used as a method of distilling water from polluted water sources. The most common application is with wastewater containing high concentrations of pollutants that cannot be removed by other methods such as filtration, biological or chemical treatment. For example, the largest field uses evaporation as a method of desalination from seawater to provide drinking water. [0003] To achieve evaporation, a large amount of heat is required, resulting in high energy consumption for most evaporation technologies. To reduce this energy consumption, most evaporation equipment is designed to reuse part of the heat in the steam generated in the evaporation process. The most common method is reuse through multiple-effect distillation (MED), where steam gen...
