Description
Technical field
The invention belongs to air dewetting technical field, and in particular to a kind of disc type film dehumidifier and dehumidification system.
Background technology
Air humidity is to influence the key factor of amenity degree.In the weather of hot humid, particularly bay-type city,
Dehumidifying is almost equally important with cooling.Research shows that the suitable relative humidity of human body is 40-60%, and too high humidity can cause
Human body produces discomfort, seriously then also results in the amount reproductions of some viruses of interior of building and bacterium.
With the development of national economy, the living standard of people improves constantly, for building the requirement of hygrothermal environment also not
Disconnected to improve, the application of air-conditioning is more and more extensive, the also more and more higher of the requirement to air-conditioning system.Power consumption of the air-conditioning system as China
Rich and influential family accounts for 15% or so of national energy-consuming, and China's most area summer high-temperature high humidity, especially South China, dehumidify energy
Duty adjusts total energy consumption 20%~40% is consumed, so humid control is to realizing that the energy-conservation of air-conditioning system has very great meaning.
Conventional air dehumidification method includes cooling method dehumidifying, solid absorbent dehumidifying and liquid desiccant dehumidifying.Cooling
Method dehumidifying is that humid air is cooled to below dew-point temperature, is removed after making the water vapor condensation in air from air.This method
Air need to be down to below dew-point temperature, ventilation state, high energy consumption are warming up to again after removing moisture.Solid absorbent dehumidifying is profit
Dehumidified with the method for some solid absorbent moisture absorptions.The disadvantage of this method is that the regeneration of these solid absorbents is tired
Difficulty, and device is complicated, and the volume ratio of equipment is huger, and cost is also high.Liquid desiccant dehumidifying is that have moisture absorption using some
Moisture that the solution of property comes in absorption air and reach dehumidifying purpose.Liquid dehumidifying regeneration is easy, and shortcoming is processing air and liquid
Body hygroscopic agent directly contacts, and easily causes air to carry hygroscopic agent secretly, further causes the corrosion of pipeline and equipment.In addition, with system
The progress of heat, solution temperature rise, can reduce heat exchange efficiency.
Meanwhile drier has very high affinity to water, water vapour can be nearby absorbed from it.Followed in desiccant cooling
In ring, drier reduces the humidity of air by the moisture in absorption air, then by routine cooling coil or other

KCHOO solution, Ca (NO3) solution, LiNO3Mixed liquor more than one or both of solution, its certain density solution equilibria
Steam partial pressure is smaller than the steam partial pressure of pure water flow surface under certain temperature, and these solution have strongly as water absorbing agent
Water imbibition.Moisture that can be in the absorption air of high speed, dehumidifies to air.
In the present embodiment, pellicle is using polyvinylidene fluoride porous film, its surface be a thin layer liquid silica gel or
Dimethyl silicone polymer thus only allows vapor to be transmitted by film to increase the hydrophobicity of film, and other gases
Film can not be passed through with liquid.
As shown in Fig. 4-a, Fig. 4-b, in the present embodiment, installing fin needs to resist the impact of fluid in two runners,
Higher strength and toughness is needed, and only pellicle does not meet this requirement generally, is made herein of water penetration non-woven fabrics,
Pellicle is attached to nonwoven surface again, and triangular fin can resist the impact of fluid made of non-woven fabrics, and not hinder water
The transmission of steam, dehumidification rate can not be influenceed, meanwhile, the fins 13 of different number wings can be installed, 4-a is four wings, Fig. 4-b
For six wings.
Embodiment 2
Main technical schemes in the present embodiment are same as Example 1, in the present embodiment unaccounted feature, using reality
The explanation in example one is applied, is no longer repeated herein.As shown in figure 5, the present embodiment and the difference of embodiment one are, each molten
Coiled cooling tube 15 is mounted with liquid stream road 10.
During work, dehumidification solution absorbs the vapor in air, and the latent heat of vapor causes dehumidification solution temperature to raise,
Dehumidification rate reduces, so when dehumidifier works, while cooling water or cooling gas are passed through in coiled cooling tube 15,
The dehumidifying heat of dehumidification liquid is taken away, is that dehumidification liquid recovers higher dehumidification rate.

As shown in figure 1, a kind of dehumidification system includes, including disc type film dehumidifier 1, fluid reservoir 2, cooler 3, second draw
Blower fan 4, regenerator 5, heater 6 (selecting solar heater), air-introduced machine 7.During work, dense dehumidification solution stream in fluid reservoir 2
Enter in disc type film dehumidifier 1, the dehumidification solution after dehumidifying absorbs vapor so that concentration step-down, makes it flow through heater 6
Heated, flowed into after the temperature needed for heating cause regeneration in regenerator 5 and carry out concentrating regenerative, the dehumidifying by regenerator 5 is molten
Liquid reverts to concentrated solution, and now solution temperature is higher, and dehumidification rate is relatively low, flows through and is cooled down in cooler 3, finally flows into storage
Storage, which remains to be again introduced into dehumidifier 1, in flow container 2 is dehumidified, and completes circulation；Outdoor fresh air is sent into disc type by air-introduced machine 7
In film dehumidifier 1, after the dehumidifying of dehumidification solution, then indoor use is flowed into；Meanwhile outdoor fresh air is sent by the second air-introduced machine 4
Enter in regenerator 5, take away the vapor in dehumidification solution.In the present embodiment, system utilizes disc type film dehumidifier 1 and regeneration
Device 5 is respectively completed the dehumidifying of air and the regenerative process of solution, and the two processes realize circulation so that dehumidification system can continue
Work.
