Description

Known ship water desalination plants with the use of. The evaporator of zigzag-like coils with collectors of float regulator P1, Achi water, taken out of the body (a vaporizer, and placed in a dryparnik with devices) for separating water droplets from steam.

In order to provide a constant, non-ferrous sea-water / set-up power supply and more complete use of the heat of the exhaust steam from the vessel's help mechanisms, the evaporator chamber was removed in the form of an evaporator connected to the steam and water spaces, a vertical L or H with a vacuum tube placed in it, filled with a boa and fixed on a brush, the upper end of which is connected with the help of a weight-bearing rocker arm with a weight with an equalized cylindrical valve mounted on the supply steam line, and for heating the evaporator coils used auxiliary mehunizmov exhaust steam, superheated via superheater mounted in .j.i: ohode boiler.

For heating the evaporator supplying the seawater, a preheater, heated by condensate of the primary steam, passed through the coil of the evaporator, was used.

FIG. 1 shows the general design of the water supply plant proposed; on fng. 2 - view of desalination plant with collectors and float chamber.

The proposed ship water desalination plant consists of an evaporator / with cyxonapHtiKOM 2, a condenser 3, a float chamber 4 connected by evaporator tubes with steam and water spaces and a steam superheater 5 installed in the chimney of a steam boiler (see Fig. D).

Desalination and compaction of the evaporator case 1, in which three horizontal evaporation coils 6 are placed, above which the steam-holding coil 7 is placed (see Fig. 2).

The case of the evaporator 1 is equipped with a steam chamber 2, in which 4 cone-shaped plates 8 are fixed. The evaporation coils 6 are connected to collectors 9 and 10. To the inlet collector 9 there is attached a float chamber 4, made in the form of a vertical cylinder with a hollow piston mounted on the rod // // , the upper end of which is connected by means of a weight-bearing rocker arm 12 with a weight 13. The rocker arm 12 is connected to a cylindrical self-unloading balanced valve 14 regulating the desalination power supply (i. Fig. 1 and 2).

When B0x is operating:; an installation of an emergency desalination unit on spent steam from auxiliary engines, nutrient, sanitary and other steam steam lines, has passed a steam superheater 5 installed in the boiler’s smoke box, raises its temperature from 108 to 135-140 and through the valve 15 is fed to a manifold 9. D.; d. The temperature of the superheated steam decreases to it by opening the valve 16 saturated steam is added.

The resulting steam with a temperature of 120-125 from the collector 9 is distributed along three coils connected in parallel, and, giving heat to evaporate the outside salt water, to the collector 10, from where it comes to heating water for feeding the water compressor, to the heater 17. Having transferred the heat of the feed water, the mixture in the form of condensate with a temperature of 70-80 °, enters the warm box 18. Part of the superheated steam with a temperature of 135-140 ° flows through the pipe through the valve 19 into the vapor protection coil 7, and, giving heat to the secondary steam, and through klapai 20 eg It is straight to the warm box 18. Secondary steam under atmospheric pressure, the passage of the steam-squeaking coil 7 rises through the sucker 2, bends around four conical plates 8, goes through the pipe through the valve 21 to the upper part of the condenser 3, which is installed half a dozenite meter

From the bottom of the condenser 3, the distillates are directed through a pipe through valve 22 to a warm box 18 for feeding the boilers or through valve 23 to the supply for household expenses.

During cleaning or repair of the boiler, in the chimney of which the steam heater is installed, desalination plant

can work without steam superheating; tel. In the 3TOJM case, the controllers 16 and 24 are opened and the valves 25, 26, 15, 19 are closed and the desalination plant is operated with a saturated batch (cf. Fig. 1).

Power isp. Ch)) itel produce with water, cool oid, condensate to it 3. Water is taken from outside the valve 27 and inlet valve 28, then enters the heater 17, where it is heated to 60-70, and is equilibrium nlindrically; valve 14 enters the evaporator 1 Water in the evaporator) is available due to the pressure in the pipe and inside the evaporator housing.

The power supply is made by the polispatel automatically using the self-regulating valve 14 and a floating device that keeps the water level in the evaporation constant. With the elevation of water observed over the water; gauge glass 29 floats up and, by means of a rod v of a lever (rocker arm) 12 connected with it, closes valve 14, thereby reducing power. When the level is lowered, the float is lowered and the valve 14 opens. Power is great.

The desalination brine is purged continuously through the pipe through valve 30 in the valve. To reduce the temperature of the renewed solution, outboard water from the sanitary pipeline is added through the valve 31.

The condenser 3 is pumped through the valve 32 by a centrifugal pump servicing the main condenser 33. When the evaporator is working, the main condenser 33 is supplied with water from the side through the valve 34. Water in this case is fed to the evaporator due to the differential pressure of the outboard water column and its level inside the evaporator housing.

The proposed water desiccator installation is simple in the device, allows the use of spent steam through lines 35 from auxiliary mechanisms, pars pumps, winches, etc., does not require continuous monitoring and

easily controlled by one bypass valve 26.

Without this water desalination unit, the auxiliary mechanisms worked with the exhaust pressure of 0.5–1 kg / cm to the feedwater heater. The pressure was regulated by valve 36. The use of heat was less effective. The proposed installation allows you to more fully use the heat of the exhaust steam.

Due to intensive circulation and continuous blowdown, scum on the surface of the evaporator coils forms very little, which allows cleaning the coils to be done once a month.

A filter 37 is installed on the mains to trap suspended particles in the feed water. Thermometers 38 are installed on the mains to control the temperature of the steam.
