SU645662A1 - Apparatus for distillation of sea and saline water - Google Patents

Description

I

The invention relates to evaporators used, for example, for producing distillate from sea and industrial saltwater, as well as for separating liquid media into fractions (for example, oil), and can be used for distillation salt containing ODs by heat sources; organic, so nerny fuel, in chemical, metallurgic ni) ukh of industries.

Multistage drills are known: a boil-off partner containing superheated water expanders, evaporator condensers; of these expanders and 1 pumps for pumping cooling condensate from stage to stage G.

The disadvantage of this evaporator is that it only allows the evaporation of heat once.

A device for generating steam, made in the form of a vortex chamber with tangential nozzles, is known in which an eruption is obtained by

a decrease in pressure in the working environment of the swirl squared hot liquid, this produces steam only due to part of the heat accumulated by the liquid 2,

Using heat from the steam for

the production of secondary hyphae by these inventions is not contemplated. The known apparatus for DISTILLEIN.IN: sea and salt water, in the vortex evaporation chamber is placed in a casing and equipped with tangent pipes for supplying and evacuating evaporated water and an axial patrol. for removal of secondary steam 1d. In this there is no heating of the evaporative coke with the heat of the secondary steam.

The aim of the invention is to improve the efficiency of the apparatus by utilizing the heat of the secondary steam. This goal is achieved by the fact that the vortex chambers are installed in series, each chamber is connected to the casing of the subsequent chamber by means of a nozzle for discharging secondary steam. FIG. 1 depicts an ash trap for distilling sea water in saline waters; in fig. 2, section A-A of FIG. 1. The apparatus contains cylindrical vortex evaporating chambers 1, placed in steam jackets 2, tangential nozzles 3 and 4, respectively, for injecting desalinated water and draining it from azcharat, axial nozzle S an of the secondary vapor removal. During operation of the apparatus, the desalinated water heated to the saturation temperature is fed under pressure into the vortex chamber, where the working medium pressure decreases and its partial evaporation occurs. Evaporation lasts until a new thermodynamic equilibrium is established. The evaporation of the first stage of the evaporator enters the steam jacket of the second stage, where it condenses, HE heats the liquid medium in the second stage of the vortex evaporator; The evaporator of the second stage enters the third stage of the evaporator steam jacket, etc. The evaporation condensate is removed from each stage of the evaporator. From the last stage, the evaporator enters the condenser. During the annular motion of a fluid in a vortex evaporator, an intense turbulence of the flow occurs, resulting in a decrease in the thickness of the boundary layer and an increase in the heat exchange coefficient between the fluid and the inner surface; evaporator. In this connection, the productivity of the apparatus of the same area of heat exchange increases in comparison with the existing heat exchangers. Apparatus of the Invention to increase its efficiency by utilizing the heat of the secondary steam, the vortex chambers are arranged in series and each chamber is connected to the casing of the subsequent chamber through a nozzle for discharging the secondary steam.
