Humidification and dehumidification water purification device with fluidized bed enhanced evaporation

Abstract

The invention discloses a humidification and dehumidification type water purification device for evaporation enhancement of a fluidized bed. The humidification and dehumidification type water purification device comprises a condensation chamber, a condenser, an evaporation chamber, an upper partition board, a lower partition board, a spraying device, a heating device and a drive device, wherein an evaporation cavity is limited in the evaporation chamber, a second gas inlet, a second gas outlet and a sewage outlet are formed in the evaporation chamber, and the second gas outlet is communicated with a first gas inlet; the upper partition board and the lower partition board are arranged in the evaporation cavity in a spaced mode so as to divide the evaporation cavity into an upper cavity, a middle cavity and a lower cavity, suspended solid particles are arranged in the middle cavity, the second gas inlet is communicated with the lower cavity, and the second gas outlet is communicated with the upper cavity. The spraying device is provided with a spraying nozzle in the upper cavity. The heating device is connected between the spraying device and a water outlet pipe. The drive device is connected between a first gas outlet and the second gas inlet. By means of the humidification and dehumidification type water purification device, water purification efficiency can be improved, the structure is simple, and cost is low.

Description

technical field [0001] The present invention relates to the field of water purification, in particular to the application of fluidized bed enhanced evaporation process and the use of humidification and dehumidification method for seawater desalination and waste water, sewage treatment, more specifically, to a fluidized bed enhanced evaporation humidification and dehumidification water Purification device. Background technique [0002] With the increase in global water consumption, natural factors such as soil erosion and human factors such as illegal discharge of factories, the damage to existing water resources has aggravated, and the shortage and pollution of fresh water resources have become major problems that seriously restrict the development of human society. Designing water purification devices to use seawater to obtain fresh water or to treat sewage is an effective means to solve water resource problems. [0003] At present, water purification methods are mainly di...

Problems solved by technology

However, these three methods require large equipment investment, high cost, high energy consumption, and high requirements for pretreatment of seawater or sewage, and are not suitable for solving small water purification needs.

Some other methods include technologies such as ion exchange, liquid-liquid extraction and dew point evaporation. Due to the high cost, these technologies have not been widely used except in some special occasions that require high water quality.

In recent years, forward osmosis membrane technology has received widespread attention and is expected to be commercialized. This technology is also costly and has not yet matured.
