Description
Technical field:
The present invention relates to a kind of solution dehumidification system, especially a kind of compound solution dehumidification system based on ultrasonic atomization technique.Belong to the air conditioner energy saving technical field.
Background technology:
The air-conditioning power consumption can account for 40% in big city total power consumption in summer such as Beijing-Shanghai, the investigation of civil buildings air-conditioning system is found, the dehumidifying energy consumption of summer air-conditioning accounts for the 20%-40% of whole air-treatment energy consumption, therefore as seen, dehumidification system energy-conservation has critical role in air conditioner system energy saving.In dehumidification system, solution dehumidification not only can be good at utilizing low-grade heat sources such as solar energy, industrial exhaust heat, and the design of system and structure can be very flexible, both can use the purpose that plays dehumidifying separately, can be used with traditional air-conditioning system again, effectively reduce its energy consumption; Employed dehumidification solution can be eliminated airborne bacterium and microorganism simultaneously, helps to improve indoor air quality.Therefore, the solution dehumidification technology has obtained paying close attention to widely and research in recent years with its incomparable advantage.
The dehumidifying tower module that wherein adopts filler is the basic Heat and Mass Transfer unit in the solution dehumidification system, also is the building block of system, and a plurality of dehumidifying tower modules can assembly be organized out multiple different solution dehumidification system form.Material filling type dehumidifying tower can utilize better simply geometry to realize bigger specific area, and heat and mass efficient is higher, is most widely used dehumidifying tower, and its major defect is: heat absorption heats up during the dehumidifying of 1 dehumidification solution; Pressure fell bigger when 2 air flow through.Did deep research for these two many scholars of shortcoming.For first dehumidifying tower that has the people to propose internally cooled dehumidifying tower and dehumidification solution is carried out the heat exchange cooling, obtained effect preferably; For second point, constantly there is the scholar to propose novel filler with high-specific surface area.In the prior art, by the generation person of outstanding talent, Zhang Weijiang is (refrigeration journal in " Metal Fill-Type Direct Evaporative Air Cooler research [J] " literary composition, 1994 (4): 28-31) and the Chen Yingzai experimental study of liquid regenerative process " a kind of honeycomb paper felt packing be used to dehumidify " (refrigeration journal Vol.28, No.3 June.2007) two kinds of form of bio-carrier has been proposed in the literary composition respectively, though but these two pieces of articles point out all that also two kinds of form of bio-carrier have improved specific area greatly simultaneously, equally not having to solve along with packed height increases the filler wetted surface area increases the same shortcoming that increases of still pressure drop.This grandson He Jiang, also spell out in " experiment of idle call metal packing heat and mass transfer performance " (the journal Vol.38 No.6 Jun.2005 of University Of Tianjin) literary composition by the generation person of outstanding talent: " experiment shows; the specific area of filler is bigger to the heat transfer and the mass-transfer performance influence of filler. but the specific area increase can cause the filler resistance to rise appreciably; therefore, can not emphasize to improve the thermal property of filler simply by the specific area that increases filler. "
Thereby further developing of packing technique has been subjected to the restriction that the dehumidifying tower requires resistance greatly.Not only to consider to improve its specific area in the filler design process, simultaneously also to consider to reduce crushing and make it have good porosity, this series of requirements makes the tremendous development of packing technique be restricted, the simultaneously simple high-specific surface area of pursuing filler must bring the increasing of filler research difficulty, and a series of problems such as cost up, processing difficulties.How to pass through under such a case in conjunction with new technological improvement dehumidification system, raising dehumidifying tower specific area improves the dehumidifying column efficiency simultaneously and seems especially important.
Summary of the invention:
For deficiency and the defective that overcomes prior art, the invention provides a kind of simply, be easy to realize, efficiently based on the compound solution dehumidification system of ultrasonic atomization technique.
The present invention is achieved through the following technical solutions: the present invention increases a solution atomization device on traditional dehumidifying column foot plinth, the solution atomization device comprises supersonic generator and spray chamber, wherein the ultrasonic transducer in the supersonic generator places the spray chamber bottom, concentrated solution is equipped with in the spray chamber bottom, and concentrated solution is flooded ultrasonic transducer.The spray chamber air inlet communicates with pending air, and the spray chamber gas outlet communicates with dehumidifying tower air inlet, and dehumidified air is discharged in dehumidifying tower gas outlet.The concentrated solution outlet of spray chamber is connected with the concentrated solution import of dehumidifying tower solution tank, and the weak solution outlet of dehumidifying tower solution tank communicates with the import of spray chamber concentrated solution by regenerating unit.
Concentrated solution is flooded ultrasonic transducer, it convert electric energy to machinery shake can, transducer is applied resonant electrical signals makes transducer produce the vibration of ultrasonic wave of scope at 1-5MHZ, this vibration of ultrasonic wave is atomized into salting liquid the salt fog particle of diameter 1-10 micron; In spray chamber, the concentrated solution atomizing particle mixes with air and fully contacts.Air is tentatively dehumidified in spray chamber this section before enter the dehumidifying tower, and this dehumidification process relies on the salt fog particle dehumidifying of atomizing to realize fully; Air and salt fog mist enter the dehumidifying tower, carry out the secondary dehumidifying, and this dehumidification process is identical with traditional solution dehumidification.
Beneficial effect of the present invention: because air brings a large amount of salt fogs into the dehumidifying tower, make the dehumidifying specific area of dehumidifying tower increase greatly, ultrasonic atomization effect simultaneously, the specific area that makes the salting liquid of equal quality produce increases greatly.Because the existence of salt fog, the tower inner ratio surface area improves, and this makes dehumidifying tower be minimized the requirement of filler, and to adopt body surface area in packed tower be not big especially and the high filler of porosity becomes feasible thereby make.And the filler porosity improves the drag losses minimizing that just means the tower that dehumidifies, thereby energy consumption also is minimized.The technology of the present invention is not only can reduce the dehumidifying tower to the filler requirement than traditional solution dehumidification system biggest advantage, reduces dehumidifying tower cost, and can improve the solution dehumidification Energy Efficiency Ratio.
