Description

459 158 10 15 20 25 30 uppfinningen bygger på kylning och utkondensering av lösningsmedlen, beror resthalten av lösningsmedel i den avgående frånluften på respektive lösningsmedels ång- tryck vid den sluttemperatur som valts. De utkonden- serade lösningsmedlen avskiljes och erhålles tack vare uppfinningen med så rena att de kan återanvändas. 459 158 10 15 20 25 30 invention is based on cooling and condensation of the solvents, the residual content of solvent in the exhaust exhaust air depends on the vapor pressure of the respective solvent at the final temperature selected. The condensed solvents are separated and obtained thanks to the invention with such pure that they can be reused.

Uppfinningen ger här stor frihet att välja mycket låga temperaturer. Den möjliggör även att värmeinnehållet i frånluften återvinnes och användes för uppvärmnings- ändamål.The invention here gives great freedom to choose very low temperatures. It also enables the heat content of the exhaust air to be recovered and used for heating purposes.

Figur Den bifogade figuren visar flödesschemat för en före- dragen utföringsform av uppfinningen.Figure The attached figure shows the flow chart for a preferred embodiment of the invention.

Detaljerad beskrivning av uppfinningen Uppfinningen skall beskrivas närmare i anslutning till den utföringsform, som visas i figuren.Detailed description of the invention The invention will be described in more detail in connection with the embodiment shown in the figure.

Från en lokal, där lösningsmedel föràngas, ledes från- luften 1, som har rumstemperatur t ex 18-20°C, först till ett filter för borttagande av fasta och flytande föroreningar t ex damm och färgrester och därefter till en anordning enligt uppfinningen. Denna innehåller först en fläkt 3 för transport av luften genom anordningen.From a room where solvents evaporate, the exhaust air 1, which has a room temperature eg 18-20 ° C, is led first to a filter for removing solid and liquid pollutants, eg dust and paint residues, and then to a device according to the invention. This first contains a fan 3 for transporting the air through the device.

Första steget i sättet enligt uppfinningen har till ändamål att ta bort så mycket vattenånga ur luften, att svårigheter på grund av isbildning inte kan uppstå i de senare stegen. Vattenângan borttages lämpligen genom adsorption i bäddar 4,5 av en adsorbent som företrädes- vis adsorberar vattenånga. Konstgjorda zeoliter ofta kallade molekylarsilar kan lämpligen användas för detta ändamål. Dessa kan nämligen framställas så, att de selektivt adsorberar vissa ämnen t ex vattenånga. I detta fall kan det eventuellt vara intressant att även 10 15 20 25 30 vb ...i LH CO 45 adsorbera koldioxid, om man önskar kyla till mycket låga temperaturer i tredje steget. Däremot kan adsorptionen av föràngade lösningsmedel hållas mycket låg. Bäddarna inkopplas växelvis med ventiler 6, 7, 8, 9 och regeneras dessemellan med varmluft 25, som inkopplas med ventiler 26, 27, 28, 29.The purpose of the first step in the method according to the invention is to remove so much water vapor from the air that difficulties due to ice formation cannot arise in the later steps. The water vapor is suitably removed by adsorption in beds 4,5 of an adsorbent which preferably adsorbs water vapor. Artificial zeolites, often called molecular sieves, can be suitably used for this purpose. Namely, these can be prepared in such a way that they selectively adsorb certain substances, for example water vapor. In this case, it may be interesting to also adsorb carbon dioxide in LH CO 45, if desired to cool to very low temperatures in the third stage. However, the adsorption of vaporized solvents can be kept very low. The beds are connected alternately with valves 6, 7, 8, 9 and regenerated therebetween with hot air 25, which is connected with valves 26, 27, 28, 29.

Den från vattenånga befriade luften passerar via en rörledning 10 till en första kylapparat 12 i vilken det andra steget i sättet enligt uppfinningen genomföras. I kylapparaten kyles luften med en värmepump, 11, 13, 14, 16. I denna komprimeras ett lämpligt köldmedium i en kompressor 13, kyles och kondenserar 14 för att sedan efter trycksänkning 16 föràngas 11 med hjälp av den inkommande föràngade lösningsmedel innehållande luften, som därvid kyles. Såsom köldmedium i värmepumpar an- vändes för närvarande vanligtvis freoner. Med dessa t ex freon 22 kan luften kylas ned till -30 ä -40°C. En del av de föràngade lösningsmedlen kondenseras ut och avskiljes 17 samt bortledes 18.The air freed from water vapor passes via a pipeline 10 to a first cooling apparatus 12 in which the second step in the method according to the invention is carried out. In the cooling apparatus the air is cooled with a heat pump, 11, 13, 14, 16. In this a suitable refrigerant is compressed in a compressor 13, cooled and condensed 14 and then after depressurization 16 is evaporated 11 by means of the incoming evaporated solvent containing the air, which then cooled. Freons are currently commonly used as refrigerants in heat pumps. With these, for example Freon 22, the air can be cooled down to -30 to -40 ° C. Some of the evaporated solvents are condensed out and separated 17 and discharged 18.

För kondensering 14 av köldmediet kyles detta med vatten eller möjligen luft, som därvid uppvärmes och ledes bort 15 för uppvärmningsändamál. Till exempel kan friskluften till lokalen värmas med detta varmvatten.For condensation 14 of the refrigerant, this is cooled with water or possibly air, which is then heated and led away for heating purposes. For example, the fresh air to the room can be heated with this hot water.

För att genomföra det tredje steget i sättet enligt uppfinningen ledes den nedkylda luften från föràngaren 11 och avskiljaren 17 till slutkylningen 19 där tempera- turen sänkes ytterligare så att kondensering av de förångade lösningsmedlen sker. Dessa avsätter sig på ytorna i kylaren 19 och tappas av 21. Den utgående luften fràn slutkylaren 19 värmeväxlas 22 med den ingående luften.To carry out the third step in the method according to the invention, the cooled air is led from the evaporator 11 and the separator 17 to the final cooling 19 where the temperature is further lowered so that condensation of the evaporated solvents takes place. These deposit on the surfaces of the radiator 19 and are drained by 21. The outgoing air from the final cooler 19 is heat exchanged 22 with the incoming air.

Ytterligare kylning 20 sker dessutom pà lämpligt sätt.Additional cooling also takes place in a suitable manner.

Detta kan t ex vara kylning med flytande kväve. Ett 459 158 10 annat förfarande, som ej illustreras i figuren, innebär att torr luft av rumstemperatur, t ex en delström av den frán vattenånga befriade luften från första steget, komprimeras, kyles, lämpligen med den från tredje steget avgående kalla luften, och får expandera t ex direkt in i kylaren 19. Hela apparaten för slutkylningen 24 isoleras lämpligen mot omgivningen. Den avgående kall- luften 23 kan sommartid användas för kylning av frisk- luft. Även om föràngningen av lösningsmedel i den aktuella lokalen upphör, kan anordningen enligt uppfin- ningen helt eller delvis användas för värmeàtervinning ur fránluft eller ur utomhusluft och för lokaluppvärm- ning.This can be, for example, cooling with liquid nitrogen. Another method, not illustrated in the figure, means that dry air of room temperature, for example a partial stream of the air vapor-liberated from the first stage, is compressed, cooled, suitably with the cold air leaving the third stage, and allowed to expand, for example, directly into the radiator 19. The entire apparatus for the final cooling 24 is suitably insulated from the environment. The departing cold air 23 can be used in summer to cool fresh air. Even if the evaporation of solvent in the room in question ceases, the device according to the invention can be used in whole or in part for heat recovery from exhaust air or from outdoor air and for room heating.
