Description

Technical Field

[0001] The utility model belongs to the technical field of thermal desalination, and relates to a desalination system using a humidification and dehumidification technology, in particular to a humidification bin of the desalination system. Background Art

[0002] Chemical industrial wastewater has complex composition and contains a large amount of inorganic salts, so it has high requirements for treatment equipment and technology. Thermal desalination technologies such as humidification dehumidification (HDH) include humidification chambers and dehumidification chambers. The humidification chamber forms concentrated liquid and water vapor through spraying, and the water vapor flows to the dehumidification chamber through the pipeline and condenses into water, thereby reducing the amount of wastewater. In order to promote the mass and heat transfer inside the humidifier, porous fillers are often used inside the humidifier to break up the wastewater droplets. However, as the desalination process proceeds, the deposited crystals and dirt will cause pipe blockage and reduce the desalination performance of the system. In other words, during the desalination process, water evaporation and changes in the temperature of the concentrated liquid will lead to the nucleation and growth of crystals with inorganic substances as the main component, and the dirt composed of colloidal particles in the wastewater will be affected by the van der Waals force, causing crystals and dirt to accumulate on the surface of structures such as pipes, fillers and shells.

[0003] Most of the crystals and dirt in the wastewater have colloidal properties. They not only interact with each other during movement, but also undergo adsorption with the surfaces they come into contact with. As the desalination process proceeds, the number of collisions between solid substances such as crystals and dirt increases, the collision frequency becomes higher and higher, and the probability of solid substances aggregating together becomes higher and higher, causing blockage of the system and pipelines. In HDH technology, porous fillers are used to break up and spread droplets, thereby increasing the evaporation area. However, the dirt in the wastewater will accumulate in the pores of the fillers, and the increasing salinity also promotes the nucleation and growth of crystals.

[0004] At present, the methods of decrystallization include using acid and alkali to crystallize the desalination system and regularly chemically clean the dirt, but this consumes a lot of chemicals, cannot achieve zero emissions in the true sense, and does not directly achieve decrystallization. In thermal desalination technology, the concentrated solution after decrystallization should be maintained at a certain temperature so that it can continue to enter the desalination system for evaporation. Therefore, the freezing crystallization method that uses the property of crystal saturation changing with temperature to decrystallize is not applicable to thermal desalination. The commonly used decrystallization method is to add an evaporation crystallizer outside the desalination system to decrystallize the wastewater concentrated to a near-saturated state. The boiling point of the concentrate is reduced by reducing pressure, and the evaporation crystallizer uses centrifugation and evaporation to separate the solid particles and liquid in the concentrate, thereby achieving decrystallization. For example, application No. 201611214327.4 discloses a dual thermal mass coupled solar hot air evaporation system and method thereof. The system recovers water vapor and the corresponding sensible heat and latent heat in the humid air, but the remaining concentrated solution is directly discharged without recycling. The system has difficulties in handling high-salt solution in actual operation, and no solution is proposed for the phenomenon of crystal scaling generated when the high-salt solution evaporates in the evaporator.

[0005] In addition, the power source of the evaporation crystallizer is electricity and high-temperature steam. The scraper designed inside the evaporation crystallizer can remove the substances attached to its surface. However, the equipment investment of the evaporation crystallizer can account for 15%-16% of the total system investment. HDH technology can use factory waste heat for desalination. When combined with the evaporation crystallizer, most of the system's power consumption and heat consumption come from the evaporation crystallizer part. In addition, when using the evaporation crystallizer for desalination, the conditions and quantity of use are easily restricted by the environment.

[0006] From the above, the heat source of HDH thermal desalination technology can be the large amount of waste heat in the factory, and HDH itself is made of plastic and is insensitive to highly corrosive wastewater. HDH has economic feasibility and high energy utilization in the field of desalination. Although the problems of crystallization and fouling inside the humidifier can be solved by adding an evaporation crystallizer externally or performing regular chemical cleaning, it is limited by the environment and energy sources, and cannot truly achieve zero emissions directly. Therefore, finding a simple and effective de-crystallization method in HDH thermal desalination technology is extremely important to improve energy utilization and achieve zero emissions.
