SU1428401A1 - Evaporation chamber for water-desalinating plant of instantaneous boiling - Google Patents

Abstract

The invention relates to desalination technology, in particular, the device of an evaporation chamber of a desalting plant of instantaneous boiling, and improves its performance. The instantaneous boiling evaporation chamber contains a housing, a condenser, a condensate collection tray, a separator, a vertical partition installed between the inlet and outlet nozzles of desalinated water to form two compartments. The inlet compartment is provided with a calibrating perforated plate placed at the height of the upper edge of the partition, which prevents the dripping of liquid droplets, and the exit compartment is equipped with inclined shoulder plates for water flow, installed zigzag at an acute angle to each other and attached alternately to the vertical partition and the wall of the housing. 3 il.

Description

The invention relates to a desalination technique, and more specifically, to a device for evaporating boil-off instant desalination chambers,

i The purpose of the invention is to increase the efficiency of the evaporation chamber.

Fig. 1 shows an evaporation chamber of a desalination boiling unit; 2 shows a section A-A in FIG. 1J in FIG. 3; a section B-t-B in FIG. one .

; The evaporation chamber of the instantaneous desalination plant doesn’t remove the body 1, the power supply supply nozzle 2, the breaker shield 3, and the otBOfla water outlet 4, a vertical partition 5 is installed in the lower part of the body. Horizontal section is installed at the cut-off height of the vertical partition 5 The pcrunner plate 6, which is supplied with dusts, and in the output compartment there are rows of plates 7 for film brine swelling, equipped with shoulders 8. The upper part of the chamber is equipped with a separator 9 and a condenser 10

The evaporation chamber operates as follows: 13 ohm.

The desalinated water through, the branch pipe 2 enters from the inlet from the chamber. Here, the water level is maintained by the height of the partition 5. Water is uniformly distributed over the entire volume of the inlet compartment by means of a baffle plate 3 "In the entrance compartment of the chamber due to the initial overheating, the brine is evaporated during puffy boiling. The vapor bubbles, having passed the perforated horizontal calibration plate 6, the separator passage, enter the working surfaces of the condensate. 10. The condensate formed during condensation vapor is collected in a tray and discharged. Without evaporating the Yoda part with a residual overheating of 2–5 ° C, overflowing through the cut of the partition 5, from the inlet chamber falls on the plate 7 of the film flow of water equipped with flanges. In the outlet compartment of the chamber, the water is combined with single phase convection; yes on a row of plates and then on the bottom of the camera body. The resulting single-phase convection 1c and steam are supplied to the working surfaces of the condenser.

10 where it condenses. The non-evaporating part of the water is removed from the chamber body through the nozzle 4 and is supplied to the next chamber, where the brine evaporation process is repeated, but at a pressure lower than in the first chamber. The resulting distillate is diverted to freshwater tanks (not shown).

The presence of a horizontal calibrating plate and the use of plates of the film runoff of water, as well as the use of a vertical partition, allowing bubble boiling and single-phase convection to be connected in one chamber, allows more complete removal of the initial brine overheating and reduction of its residual overheating while improving the quality of the resulting disperse - Ty.pl ta. Thus, the performance of the evaporation chamber and the desalination plant as a whole is improved, since removing overheating by 1 C allows, at the same costs, to increase productivity by 2.5-3.0%, which reduces the cost of produced fresh water .

Thus, the use of the proposed evaporation chamber allows increasing productivity, reducing fuel consumption for producing a unit of fresh water volume and reducing the cost of producing fresh water. The invention can be applied both in the design and manufacture of installations of instantaneous boiling up, and in upgrading existing evaporation chambers of desalination installations of instantaneous boiling.
