Definitions
- the present invention relates to a method for obtaining a treated liquid from a contaminated liquid by evaporation and condensation by means of heated air as a carrier material.
- the invention relates to a device for obtaining a treated liquid in the form of a condensate from a contaminated liquid by evaporation and condensation, in particular according to the inventive method.
- the invention primarily serves to recover drinking water from various sources of water, such as contaminated river water, brackish water or seawater, but may also be used to recover volatile solvents from liquid mixtures, with or without solid contents.
- the present invention therefore has as its object to provide a method which allows the cost-effective and mobile recovery of pure liquids, in particular drinkable water.
- the object of the invention is to provide a device for extracting pure liquids, in particular drinkable water, which preferably requires no additional electrical energy, is essentially maintenance-free, consists of modular components, which are light with the means even in rough areas can be transported to the place of use, can also be assembled by non-professionals, are cost-effective in their production and can be operated with locally available energy, such as solar energy or waste heat from existing heat sources
- This object is achieved in terms of the method, starting from a method of the type mentioned in the present invention that the air is conducted in a substantially closed circuit by natural convection, the air heated in an air collector, then a Kas- It passes through the evaporated evaporator, which is then flowed through by the contaminated liquid, in order subsequently to discharge the moisture absorbed in the cascade evaporator in a downstream condenser before it re-enters the air collector.
- a substantially closed circuit is provided with air as a substrate at atmospheric pressure, in which a vertically or obliquely arranged air collector with means for receiving heat from an external heat source and Dissipate this heat to the air, a cascade evaporator and a condenser are integrated, so that the air moves through natural convection through the circulation.
- the device is used in particular for carrying out the method according to the invention.
- Alternative embodiments or advantageous developments of the method and apparatus are the subject of the dependent claims.
- the method is based on the consideration that for the evaporation of a liquid a significantly lower energy input is required than for their evaporation and the performance of a device of the generic type substantially from the heat content of the contaminated liquid and the carrier medium, as well as their temperature difference in the separation of the treated liquid depend on.
- the process parameters should be adapted in particular to the local conditions at the site and the highest possible heat recovery be possible to create temperature and energy input optimized conditions.
- the stated objects are achieved and considerations implemented by the recovery of a treated liquid from a contaminated liquid by evaporation and condensation by means of heated air is carried out as a carrier material, wherein the air transported in a substantially closed circuit by natural convection becomes.
- an air collector for heating the carrier air a cascade evaporator and a condenser for cooling the carrier material air and recovery of the treated liquid are integrated as a condensate.
- any water source can be used as the contaminated liquid, for example sea, lake, river, spring, groundwater or brackish water. This water may well be contaminated with suspended matter or dissolved substances. All of these undesirable ingredients are just as safely retained in the contaminated, concentrated liquid as they are in an evaporation evaporation.
- the inventive method is also suitable for the recovery of volatile solvents from liquid mixtures. Only in the case of equipment wetted by the liquid or its vapors, the selection of the material must be considered.
- the structure of the device is also simplified by the fact that the process is operated at atmospheric pressure.
- An oblique arrangement is particularly useful when the air collector is designed as a solar collector.
- the air below the translucent cover is heated by the solar radiation, whereby this effect is supported by a collector base made of blackened metal sheet. Radiation losses can be significantly reduced by known insulation measures.
- heat from other heat sources for heating the carrier air via corresponding installations in the air collector, for example spiral or register tubes.
- exhaust gases from a generator, process heat, geothermal energy, etc. may be considered.
- the solar radiation is assumed to be the energy source.
- the embodiment of the cascade evaporator shown here is merely illustrative of the principle and therefore does not limit its construction.
- the air guided in the essentially closed circuit 1 is heated in the air collector 2 by the solar radiation 3 and / or by indirect transfer of the waste heat from another heat source, rises by natural convection and enters the cascade evaporator 4 through the inlet opening 15 , in which a predetermined number of horizontal or slightly inclined Verdunsterblechen 5 are arranged so that in the cascade evaporator 4 - preferably via a siphon-like installation 17 - introduced, contaminated liquid 6 on its way through the Kaskadenverdunster 4 has the longest possible way. In this case, part of the liquid in the form of vapor is taken up by the hot air 7 which slides over the liquid film.
- the residue of contaminated liquid 6 concentrated with the impurities is discharged in the lower region of the cascade evaporator 4, preferably via a siphon-like installation 18, and disposed of in a suitable manner.
- the saturated with moisture hot air 7 is supplied through the outlet opening 16 from the cascade evaporator 4 out of a condenser 8, in which the heat content of the hot air 7 - preferably by indirect contact with fresh contaminated liquid 6 - is deducted.
- the resulting in droplet form condensate 9 is discharged from the condenser and the cooled transport air flows back into the air collector 2 a.
- the air collector 2 is arranged obliquely or vertically, to support the natural convection of the transport air.
- the air convection is supported by an additional fan 10.
- the inflow of contaminated liquid 6 into the condenser 8 and further into the inflow line 11 to the cascade evaporator 4 takes place via the pump 12.
- the pump 12 it is also possible for the contaminated liquid 6 directly, so without preheating in the condenser 8 via an entry device 13 of any type the cascade evaporator 4 supply.
- the entry of the contaminated liquid 6 into the cascade evaporator 4 via the feed line 11 preferably takes place via a siphon-like installation 17.
- a siphon-like installation 18 is preferably also provided in order to ensure a largely closed circuit 1 to ensure.
- the feed line 11 for the contaminated liquid 6 ends in a distributor device 19, for example a transverse channel, which is arranged on or above the first evaporator plate 5.
- the evaporator plates 5 are supplied with heat via additional devices, not shown here, in order to compensate for excessive cooling due to evaporation energy.
- additional devices may be, for example, outwardly projecting metal sheets heated by the sun or by other heat sources, which are in good heat-transmitting contact with the evaporator sheets 5.
- many other constructions familiar to the person skilled in the art are also conceivable. In order to prevent heat loss of the cascade evaporator 4, it is also possible to form this heat-insulated.
