    • Process and device for distilling fresh water from sea water by a combined multi-stage film (VTE)-flash-(MSF)-evaporation process, in which the sea water after passing through the first VTE-process stage (Fst1) and before entering the next VTE process stage is fed to a storage point where it is subjected to flash evaporation in at least one MSF process stage (vsT1-3). The fresh water distillate and brine condensate pass jointly to all subsequent VTE process and MSF process stages. The steam (28) serving to heat up the sea water is fed through all evaporation stages consecutively. The exhaust vapor arising during the last VTE process stage is extracted, cleaned (49) of brine condensate and compressed (21), and enriched with water (52), so that a state of saturated steam is achieved. The saturated steam is fed again to the first VTE process stage at the temperature and pressure selected for the first VTE process stage. The inert gases arising during evaporation in the individual VTE process stages are conveyed away together with the fresh water distillate in the same flow direction as the residual steam, consisting of the distillate or condensate and primary steam. The extraction of the inert gases (35) is performed at the end of the condensation stage of the sea water pre-heater.

    • The invention concerns a method for evaporation and possibly distillation of liquids by means of a heat pump. By using a heat pump (2), energy is taken from energy reservoirs (1) such as rivers, lakes, sea water, air, sun or ground heat. It is however difficult to obtain temperatures high enough to evaporate water at atmospheric conditions. According to the invention, low temperature heat is utilized by means of a heat pump by using the condenser (high pressure part) of the heat pump to evaporate liquids in an evaporator (4') at a pressure lower than the atmospheric pressure, and thus at a lower evaporation temperature. A pump or a compressor (10) after the evaporator (4') together with a pressure reducing device (9) at the inlet of the evaporator (41) ensures lower evaporation pressure. To fully utilize the heat energy from the heat pump, the liquids may be preheated in heat exchangers (5) before the pressure reducing means, or as part of the same means. To achieve higher temperature and pressure of the evaporated liquids, said liquids are further compressed by means of compressors (10), or alternatively by heating in intermediate heat exchangers (11) in order to achieve the desired temperature level. In the case of distillation, one stage will be required for each distillate. In addition to compressors (10), intermediate heat exchangers (11) and draining devices (12), pumps (13) are required to maintain desired recondensation pressure, possibly also valves (14) to insure correct dosing of residual products and distillates to collecting devices (15).
    • 本发明涉及通过热泵蒸发和可能地蒸馏液体的方法。 通过使用热泵(2),能量来自诸如河流,湖泊,海水,空气,太阳或地热的能量储存器(1)。 然而难以在大气条件下获得足够高的蒸发水的温度。 根据本发明,通过使用热泵的冷凝器(高压部件)利用热泵利用低温热,以在低于大气压的压力下蒸发蒸发器(4')中的液体,从而 在较低的蒸发温度。 蒸发器(4')之后的泵或压缩机(10)与蒸发器(41)入口处的减压装置(9)一起确保较低的蒸发压力。 为了充分利用来自热泵的热能,液体可以在减压装置之前的热交换器(5)中预热,或者作为相同装置的一部分。 为了实现蒸发的液体的更高的温度和压力,所述液体通过压缩机(10)进一步压缩,或者通过在中间热交换器(11)中加热来实现所需的温度水平。 在蒸馏的情况下,每个馏出物需要一个阶段。 除了压缩机(10)之外,需要中间热交换器(11)和排水装置(12),泵(13)以保持所需的再冷凝压力,可能还需要阀(14)以确保残留产物和馏出物的正确计量以收集 设备(15)。
