Description
Technical field
The present invention relates to a kind of solar lithium chloride dehumidifier and dehumidifying process thereof.
Background technology
Because industrial production and human lives's needs, people find a lot of dehumanization methods in the air conditioner dehumidification field.Comprise: cool air to below the dew-point temperature, airborne moisture is separated out; Pressurization raises airborne steam partial pressure, and airborne steam is separated out; Solid or fluent material that employing has moisture-absorption characteristics directly contact with air, absorb airborne moisture etc.Because the liquid dehumidifying employing has the stronger salting liquid of wettability power and directly contacts with air as moisture absorption medium, and salting liquid and steam partial pressure are fully utilized, the effect of drying is better.
The existing lithium chloride dehumidifier that is used for the air humidity adjusting, as the KATHABAR dehydrating unit of the U.S., it is industrial to be widely used in medicine, food etc.At present in the liquid dehumidifying device to the hygroscopic solution concentrated system of regenerating, generally use other energy such as coal, electricity to heat concentrated hygroscopic solution.After the cold and hot exchange of evaporator of refrigerator is at present adopted usually and obtained cold water, reduce the temperature of salt solution again by heat exchanger with cold water.This multi-level cold and hot exchange must cause the loss in the energy replacement process to increase.Simultaneously, be used for though heat content increases, being discharged after air to refrigerator condenser cooling is heated.Not only waste energy, also cause pollution surrounding enviroment.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of energy-conservation liquid dehumidifying device one solar lithium chloride dehumidifier and dehumidifying process thereof are provided.
One of basic design of the present invention is: the lithium chloride solution to the regenerator of flowing through in the liquid lithium chloride dehumidifier carries out solar energy heating earlier, promptly utilizes the lithium chloride solution heating of solar energy to need regeneration; Adopt existing electrical heating as auxiliary heater means in case of necessity again.Do not use boiler, help environmental protection, with energy savings.
It two is by changing in the liquid lithium chloride dehumidifier, form the condenser of refrigeration machine and the heat exchange process flow process of evaporimeter, the evaporimeter that is about to refrigeration machine directly places the lithium chloride solution that is used for dehumidifying, lithium chloride is directly lowered the temperature, exempt to adopt chilled water to cool off indirectly, and the loss of refrigeration capacity that causes of multi-stage heat exchanger; Also can further utilize the air that is heated intensification by condenser in the refrigeration machine, improve the regeneration efficiency of lithium chloride solution, avoid condensation heat directly to drain into atmosphere simultaneously, surrounding environment is polluted, improve efficiency of energy utilization, realize the bi-directional energy-saving purpose.Also can use one of them separately.
Therefore, the present invention is the innovation to prior art, the regenerating unit, main jet pump that it comprises regeneration cycle pump and regeneration case with remove wet tank at interior dehydrating unit and give the dehumidifying liquid heater that regeneration is heated, it is characterized in that described heater is solar heat collector and/or electric heater unit.
Consider further and raise the efficiency that it also can comprise the refrigeration machine of being made up of evaporimeter and condenser, and the evaporimeter of refrigeration machine is arranged in the liquid medium except that wet tank bottom; And be communicated with the air inlet end that is guided to the regeneration case by blower fan through the cooling air of refrigerator condenser.

Wherein 1 solar heat collector, 2 evaporimeters, 3 condensers, 4 electric heaters, 5 regeneration casees 6 remove wet tank 7 regeneration cycle pumps 8 blower fans 9 main jet pumps
The specific embodiment
As Fig. 1, the present invention includes regeneration cycle pump 7 and regeneration case 5 at interior regenerating unit and the heater of giving the dehumidifying liquid warming, it is characterized in that described heater is solar heat collector 1 and/or electric heater unit 4.
As same embodiment, it also can comprise the refrigeration machine of being made up of evaporimeter 2 and condenser 3, and the evaporimeter 2 of refrigeration machine is arranged in the liquid-liquid except that wet tank 6 bottoms; And the wind of process refrigerator condenser 3 is connected to the air inlet end of regeneration case 5 through blower fan 8.
Dehumidification process: the regeneration technology and the spray cooling dehumidification process that comprise the liquid that dehumidifies, the regeneration technology of liquid of wherein dehumidifying is that lithium chloride liquid in the regeneration case 5 is by regeneration cycle pump 7, g from regeneration case 5 lower ends holds through the f of electric heater unit 4 to the top of regeneration case 5, and sprays in regeneration case 5 through water tank e, the pump of solar heat collector; The air that is heated after the intensification by the condenser 3 of refrigeration machine is guided to the air inlet c end of regeneration case 5 bottoms by the b end via blower fan 8,
The spray cooling dehumidification process then dense lithium chloride liquid of evaporimeter 2 coolings of mountain refrigeration machine is removed spray in the wet tank 6 through main jet pump 9 by the I end that removes wet tank 6 bottoms to the h end on top.
The flow process of representing as the arrow among Fig. 1 of the present invention: the lithium chloride liquid in the regeneration case 5 of liquid lithium chloride dehumidifier is flowed to by the g end on the loop of f end solar heat collector 1 is set, and the lithium chloride liquid that is flowed to the f end by the g end is heated.Because the energy of sunshine is constantly to change, the temperature of hygroscopic solution can not satisfy when regenerating requiring of concentrating after being heated, and controls 4 pairs of lithium chloride liquid of electric heater automatically by control system and assists heating.Regenerative pump 7 provides safeguard for the uninterrupted circulation of lithium chloride liquid.
As Fig. 1, the present invention realizes that to the condenser 3 of refrigeration machine in the liquid lithium chloride dehumidifier and evaporimeter 2 the concrete scheme of bi-directional energy-savings is: the evaporimeter 2 of refrigeration machine is directly placed lithium chloride solution except that wet tank 6 bottoms, lithium chloride liquid is directly lowered the temperature.After changing the cold and hot exchange employing acquisition cold water of existing evaporimeter, reduce the multi-level cold and hot exchange process of brine temp again by heat exchanger with cold water.Reducing energy resource consumption effectively reaches more than 15%.And will be heated air after the intensification by refrigerator condenser 3 by a end, be guided to the air inlet c end of regeneration case 5 by blower fan 8 by the b end of condenser 3.Change the existing energy waste phenomenon that the air that increases heat content through refrigerator condenser 3 heat exchanges is discharged, also improved thermal pollution surrounding enviroment.Main jet pump 9 will be delivered to the h end by the i end that removes wet tank 6 bottoms through the lithium chloride liquid after evaporimeter 2 coolings of refrigeration machine, to guarantee continual spray dehumidifying.
Remove the k end pipeline of wet tank 6 bottom j end, be used for balance lithium chloride strength of fluid and liquid level to case 5 bottoms of regenerating.
Consider the corrosion of lithium chloride liquid to common metal, the evaporator of refrigerator 2 in this case adopts the manufacturing of pure titanium material.Other have the surface that directly contacts with lithium chloride liquid, all should be corrosion resistant materials.
The present invention who constructs thus makes full use of the natural energy resources of the sun, and is pollution-free to surrounding enviroment, the dehumidification rate height, and it is effective to dry.
