Description

Vapour extraction device
Technical field
The present invention relates to vapour extraction device, more specifically, relate to the device of from air, removing water vapour and the devaporizer that comprises such device.The invention still further relates to a kind of method of from air stream, extracting steam.
Background technology
Vapour extraction device conventionally is being used for carrying out dry a lot of situations when the steam content of needs minimizing air stream or to air stream.Particularly, often need from air stream, remove too much moisture at heating ventilator with in air-conditioning system.Other situations that also may extract water vapour comprise dryer, industrially drying and dehumidifier.
A kind of vapour extraction device that uses in the drum-type clothes drier is a condenser.Warm air with saturated vapor passes through heat exchanger, and cools down in heat exchanger.More airborne water vapours are condensate on the surface of heat exchanger and are collected.The cooling air that leaves condenser carries less moisture, and absolute humidity is than reducing in the porch.But still keep the saturated with moisture state.The characteristics of such condenser are that they can only be worked under the situation of air near the saturated line of 100% humidity.Need additional heating steps with reduction relative humidity and away from saturated line.
Carry out drying for humidity being lower than 100% unsaturated air, used hygroscopic material routinely.The known a kind of conventional equipment of people is a desiccant wheel, and utilizes drier such as silica gel to absorb moisture.Drier is arranged on the carrier layer, and coiling or fold are to form the big many passages of surface area.Carrier layer is rolled-up or be arranged to the structure of a runner shape, and passage is parallel with the axis of runner.In use, the air that will be dried is crossed first sector (sector) of runner as first circulation of air.Greater than the affinity to air, and the agent that is dried of airborne moisture absorbs drier to the affinity of water.Especially silica gel is extremely effective, and it is that its several-fold water of weight is until finally reach capacity that silica gel can absorb.In operation, the partial rotation that becomes saturated of runner rotation and runner is left first air stream.They are exposed in second high temperature air stream then.The water that evaporates absorption is effectively crossed in second circulation of air makes drier become dry.In order to evaporate these water, need be equal to the big energy of evaporation latent heat.Such desiccant device is relatively large and heavy usually.Recently, developed another kind (intelligence) material, this material can absorb predetermined substance selectively, and in response to stimulating these materials is discharged.The LCST polymer is the profit in these materials.These materials are because they have when so-called lower critical solution temperature (LCST) state of change, the ability from hydrophilic relatively modality conversion to hydrophobic relatively form and known.These polymer mainly are used to biomedical applications at present.The example of this material sees European patent EP 501 301, and it is incorporated into this for your guidance in full.
One of field that steam extraction is useful is the evaporative cooling system field.Evaporative cooling system utilizes the water evaporation latent heat to extract heat in air stream.Indirect evaporation cooler and " Dewpoint cooler " flow product air stream cooling becoming control air by evaporation.If control air stream has had higher relatively humidity, then the amount of its water vapour that can absorb is limited.One of such Dewpoint cooler example is referring to WO03/091633, and it is incorporated into this for your guidance in full.Another device sees U.S. Pat 6,050,100, and it is incorporated into this for your guidance in full.How the document can be attached to the system that comprises indirect evaporation cooler to a kind of desiccant wheel is illustrated.Desiccant wheel regeneration needs a burner, needs a lot of energy inputs.In addition, the heat that moisture is absorbed with rotary wheel regeneration can be heated to empty stream up to 80 ℃.Therefore, in order to improve effective cooling capacity, it is desirable a kind of effective ways that reduce the humidity that sucks air being provided for such devaporizer.It still should be minimum carrying out the steam extraction energy needed.
Therefore just need alternative vapour extraction device, this device can turn round under the situation away from saturated line, and does not need to improve the energy input.This device should be cheap, production easily, and volume is less relatively, being attached in the existing system better.
Summary of the invention
According to the present invention, a kind of device that extracts water vapour from fluid stream is provided, attempt reducing some above-mentioned shortcomings.This device comprises the flow channel that is used for fluid stream; Be arranged in a certain amount of selectivity absorbing material of flow channel, this material has first state and second state, and this material can keep the water of first higher amount in first state, and this material can keep the water of the second low amount in second state; This device also comprises actuator, is used for optionally material being transformed into second state from first state, thereby discharges the product that surpasses second amount.After having absorbed certain water gaging, be transformed into second state by impelling material from first state, this material of can regenerating effectively.This material can be used for further absorbing steam once more then.Clearly, the second low amount can be zero substantially, does not therefore keep a lot of water in second state.Yet because this type of properties of materials should be understood this material and always have minimum hydrophily, and remain with a certain amount of water in second state.Suitable material also can be called as the stimuli responsive material, because these materials can be transformed into second state from first state in response to stimulating.In the present context, will be referred to the absorption of moisture, however, hygroscopic material also should be thought and is contained in the scope of this term.
According to preferred form of the present invention, device comprises carrier structure, and material is arranged on the carrier structure.In the present context, term " is arranged on " the following situation that is understood to include: material is the part of carrier structure.Carrier structure can be paillon foil or silk screen, and can be by forming as metal or plastic material.But also unusable paper or cardboard.Preferably material is disposed in the flow channel, so that relatively large surface area and relatively low flow resistance to be provided to fluid stream.Particularly, these materials or carrier structure can adopt the form of a plurality of passages, and be parallel with flow direction with the mode of prior art desiccant wheel.Alternatively, the mesh-structured of opening provides favourable flow behavior, because they can stimulate turbulent flow and help to reduce whole flow resistance.More preferably, material should keep solid or gel form, to keep structural form and to guarantee attached on the carrier structure.

In order to use in water vapour extracts, material can be selected as at first state hydrophilic relatively, and hydrophobic relatively at second state.In a kind of operation format, in first state, absorbed water vapour after, material can discharge aqueous water when being transformed into second state.In this case particularly importantly, when material absorbs steam, the phase transformation of liquid taking place to change to from steam, and does not carry out inverse process when being transformed into second state release water.Therefore, when conversion, from material, discharge the water energy needed that water institute energy requirement is less than evaporation similar quantity from silica gel or similar drier greatly.
Typically can be used in the material that extracts water vapour is stimulus responsive polymers, more specifically the LCST polymer.These materials can this state from hydrophilic relatively modality conversion to hydrophobic relatively form change ability and known because they have when so-called lower critical solution temperature (LCST).The LCST polymer presents the reversible solubilized-insoluble variation of heat in response to variations in temperature in the aqueous solution.A kind of form of LCST polymer be poly-(N-N-isopropylacrylamide) (PNIPAM).Other LCST polymer comprise polysilane and poly-silicon alkynes (polysilyne), as poly-(4,7,10-three oxygen undecyl silicon alkynes (trioxaundecylsilyne)) with gather (4,7,10,13-four oxygen myristyl silicon alkynes (tetraoxatetradecylsilyne)), poly-(dimethylamino ethyl methacrylate) (PDMAEMA), use ethyl and isopropyl group De Ju oxazoline, particularly poly-(2-ethyl-2-oxazoline) (PETOX) and poly-(2-isopropyl-2-oxazoline).When improving the temperature of this type of aqueous solutions of polymers, at lower critical solution temperature (LCST) reversible being separated takes place.In the aqueous solution of the environment temperature that is lower than LCST, polymer is rendered as highly folding with coiler (coil).When being higher than LCST, the framework of polymer becomes the structure that stretches more, and water is released.By adding inorganic salts or comonomer, the position of LCST may be adjusted to a very big temperature range (from 27 ℃ to 75 ℃).In addition, by adding horizontal bridging agent, this stability of structure can be enhanced, and remains on solid or gel form to guarantee material.Under the situation of using poly-(ethane oxazolin), find that the horizontal bridging agent (2-isopropenyl-2-oxazoline) that adds more than 30% can stop this polymer to become liquid when absorbing water.
Preferably, material response is transformed into second state in heat from first state, and actuator comprises heater.The preferred operations form of polysilane is that heating reaches LCST to cause the generation of conversion.When using in atmosphere control system, LCST can be configured to be higher than a little the inversion temperature of the maximum temperature that runs into usually.Material is heated to this inversion temperature causes that these materials regenerate.However, inversion temperature will still be lower than about 100 ℃, because rise to boiling and lot of energy loss that such temperature can need water.
Other activation form can be used for making material to be transformed into second state from first state, for example, and in response to electromotive force, electric current, magnetic field, electromagnetic radiation, pH, vibration or mechanical stress.
Preferably, device also comprises the drainage arrangement of the water that is used to collect release, and these water can be collected for later use.Adopt this mode, this device can be used for providing clean fresh water by extracting the wet air that flows top, ocean for example.For the ease of collecting, can provide the gravity flow structure of leading to drainage arrangement.Alternatively or in addition, also can use collection centrifugal or that vibrating device improves liquid.
Be associated with the absorption of water vapour, the latent heat of evaporation/absorption will cause the rising of temperature.This may cause warming of fluid stream and material.To add hot fluid stream for the temperature that material maintained hope and/or in order preventing, the heat exchange with surrounding air or another fluid for example can be provided.This can be by on flow channel or suitable fin is set on every side, or by subsequently the guiding of fluid stream being realized by heat exchanger.
This device and evaporation-cooled device, preferred Dewpoint cooler combines particularly useful, and wherein in use, fluid stream is directed into the porch of evaporation-cooled device working fluid from flow channel.Adopt this method, the fluid that enters cooling device can be dehumidified, and absorbs to allow more moisture in cooling procedure.
