Embodiment Construction

[0016] The invention is mainly used for seawater desalination, that is to say for producing fresh water from brine. The device according to the invention is therefore advantageously installed on the coast in order to be able to obtain from the sea the almost unlimited amount of required brine.

[0017] The apparatus according to the invention comprises an evaporator side and a condenser side. Figure 1 contains a dotted line A, on the right hand side of which is the evaporator side and on its left hand side the condenser side. The evaporator side includes a raw water tank 1 designed as an upwardly open tank and fed with seawater by a pump 2 . Under the raw water tank 1, the lower water level cylinder piston unit 3 is arranged, which includes a piston 4 arranged in the cylinder, which is connected to the piston 6 of the same stroke cylinder piston unit 7 through the piston rod 5, and the cylinder piston unit 7 is controlled by hydraulic pressure or It is preferably pneumatical...

Abstract

When fresh water is produced from salt water or similar by evaporation of untreated or crude liquid in an evaporation device under partial vacuum and by vapour condensation in a condensation device connected with the vapour outlet of the evaporation device a high degree of evaporation and cost effectiveness can be obtained in that the evaporation device and the condensation device in a disconnected condition, are filled with crude or clean liquid, respectively, and are subsequently exposed to a partial vacuum created by volume enlargement under hermetically sealed conditions and that the evaporation device and the condensation device are not flow-connected with each other until they are under partial vacuum.

Description

technical field [0001] The present invention relates to a process and apparatus for the production of clean liquid from untreated liquid, more particularly to the production of fresh water from brine by evaporating the untreated liquid under partial vacuum in an evaporating device and steaming in connection with the evaporating device The steam is condensed in the output condensing unit. [0002] The invention also relates to a device suitable for carrying out such a process, having at least one evaporation device capable of being supplied with untreated liquid, in which a partial vacuum can be generated; and at least one condensation device, which can be connected by The line is fed with steam from at least one upstream evaporation device. Background technique [0003] Such a process and device are known from DE 33 45 937 A1, in which the connecting line between the evaporator and the condensing device cannot be shut off. In order to create the desired partial vacuum, the...
