Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in the figure, be a preferred embodiment of the present utility model.
Dry and fresh water based on solution dehumidification is produced a combined unit, comprises hothouse 1, reverse osmosis unit 2 and solution dehumidification device 3; Solution dehumidification device 3 is prior art, generally comprise the spray structure 31 that is positioned at device case, and salting liquid is pumped to the interior circulation solution pump 36 of spray structure 35, be usually used in air-conditioning system, solution dehumidification is exactly the solution that utilizes some good hygroscopicity, such as lithium bromide, lithium chloride, the solution such as calcium chloride are processed air to be processed, at the processed air-steam partial pressure of dehumidifying side, be greater than the partial pressure of water vapor of concentrated solution, utilize pressure differential between the two, water vapour is passed to solution from air, solution concentration is thinning.In regeneration side, process is contrary, to the solution processing of regenerate, is equally also to utilize the partial pressure of water vapor between regeneration air and solution poor, and spent regeneration solution continuation dehumidifies to processed air.So loop.
Between hothouse 1 and solution dehumidification device 3, by pipeline, be connected to form independently air circulation loop, between reverse osmosis unit 2 and solution dehumidification device 3, by pipeline, be connected to form independently salting liquid closed circuit; The pipeline of air circulation loop is provided with air exhauster 6, and salting liquid closed circuit is provided with solution pump, and the water outlet of reverse osmosis unit 2 is drawn by outlet pipe 23.
The gas outlet 11 of hothouse 1 is communicated with the inlet end 31 in solution dehumidification device 3 by outlet pipe 4, and air exhauster 6 is arranged on air inlet pipeline 4, and the air inlet 12 of hothouse 1 is communicated with the outlet side 32 in solution dehumidification device 3 by air inlet pipeline 7; Outlet end 33 in solution dehumidification device 3 is communicated with the solution inlet port 21 of reverse osmosis unit 2 by feed liquor pipeline 8, the taphole 22 of reverse osmosis unit 2 is communicated with the liquid feeding end 34 in solution dehumidification device 3 by fluid pipeline 10, and solution pump 9 is arranged on fluid pipeline 10.Feed liquor pipeline 8 is provided with cooler 5, because the salting liquid dehumidifying through solution dehumidification device 3 will absorb heat, the effect that enters its absorption water vapour in solution dehumidification device 3 through cooled salting liquid is better.In solution cooler 5, being provided with spirals arranges the water pipe 51 passing through for cold water, and the import of this water pipe 51 and outlet all expose outside solution cooler 5.
Operation principle and the process of this device are as follows: the biology material with dry is placed in hothouse, and the operation of this device is comprised of salting liquid (LiCl etc.) circulation and air circulation.From hothouse 1 moist Cryogenic air out, driving, air exhauster 6 enters in solution dehumidification device 3, steam in humid air is absorbed by the salting liquid in solution dehumidification device 3 (LiCl etc.), the air flowing out after solution dehumidification device 3 will become dry air, then by air inlet pipeline 7, enter again in hothouse 1, to being positioned at the biology material of hothouse 1, be dried; The salting liquid of dehydrating unit 3 absorbs after steam at solution dehumidification assembly, become moisture rare salting liquid, this rare salting liquid enters reverse osmosis unit 2 after being passed solution cooler 5, by wherein contained humidity is separated with salt, make fresh water, the dense saline solution of going out after moisture content is entered solution dehumidification device 3 by solution pump 9 pumps simultaneously, completes circulation.This device is compared not only and can be prepared fresh water with existing drying device, and without extra electric heater, openning is dried, and has advantages of that drying efficiency, high energy consumption are low.
The principle of reverse osmosis unit: when the weak solution of same volume and dope being placed in respectively to the both sides of a container, centre intercepts with pellicle, solvent in weak solution will naturally pass pellicle, to concentrated solution side flow, the liquid level of concentrated solution side can exceed certain altitude than the liquid level of weak solution, form a pressure differential, reach osmotic equilibrium state, this kind of pressure differential is osmotic pressure.If when concentrated solution side applies a pressure that is greater than osmotic pressure, the solvent in concentrated solution can flow to weak solution, the opposite direction of the flow direction of this kind of solvent and original infiltration, and this process is called counter-infiltration.The material seeing through is had to optionally film and be called pellicle, the film that generally can only can not see through through solvent solute be referred to as desirable pellicle.For example, for example, when the weak solution of same volume (fresh water) and concentrated solution (salt solution) are placed in respectively to the both sides of pellicle, the solvent in weak solution will be naturally through pellicle and spontaneously to concentrated solution one side flow, this phenomenon is called infiltration.When infiltration reaches balance, the liquid level of concentrated solution side can exceed certain altitude than the liquid level of weak solution, forms a pressure reduction, and this pressure reduction is osmotic pressure.The size of osmotic pressure depends on the intrinsic property of solution, relevant and irrelevant with the character of pellicle with kind, concentration and the temperature of concentrated solution.If when concentrated solution one side applies a pressure that is greater than osmotic pressure, the flow direction of solvent, by the infiltration opposite direction with original, starts from concentrated solution to weak solution one side flow, and this process is called counter-infiltration.Counter-infiltration is a kind of reverse travel motion of infiltration, a kind of under pressure-driven, separation method solute in solution and solvent being separated by means of the selective retention effect of pellicle, it has been widely used in the purification of various liquid with concentrated, wherein the most general application example is in water treatment technology, with reverse osmosis technology by Impurity removals such as the inorganic ions in former water, bacterium, virus, organic matter and colloids, to obtain high-quality pure water.
