Description

one

The invention relates to the energy sector and can be used to recover heat from the steam generators' blowdown water.

The closest to the present invention is a continuous blowdown spreader, comprising a housing with an upper steam discharge pipe, provided with a conical socket at the inlet end and a vessel placed in the housing, communicating with the latter in water by means of holes and having a fitting for supplying purge water and a nozzle for steam removal installed in the conical socket of the steam pipe

one.

The disadvantage of such a continuous blowdown spreader is its reduced efficiency, so KaiK water after the spreader is not used.

The aim of the invention is to improve the economy.

This goal is achieved by the fact that the continuous blowout expander is equipped with a device for treating water, made in the form of a vertical chamber with upper and lower nozzles, respectively, for draining purified water and removing sludge, and located in the chamber snail swirler

with an inlet mixer connected to the lower part of the body and to an additional source of raw water through an additional device for magnetizing the latter, and the outlet section of the swirler communicates with the cavity of the chamber.

FIG. 1 schematically shows a continuous product expander, a general view; in fig. 2 shows section A-A in FIG. one.

The expander - continuous purge comprises a housing 1 with an upper steam exhaust pipe. 2, provided with a conical bell 3 at the inlet end, and a vessel 4 disposed in the housing 1, communicated with the latter in water by means of the holes 5 and having a nozzle 6 for supplying purge water and a nozzle 7 for removing steam installed in the conical socket 3 steam discharge In addition, the expander of continuous blowing is equipped with a water treatment device, made in the form of a vertical chamber 8 with upper and lower nozzles 9 and 10, respectively, for draining purified water and surprising sludge, and located in the chamber 8 telem.11 with mixer at 12

the entrance. The mixer 12 is connected to the lower part of the housing 1 and to an additional source of raw water (not shown) through an additional device 13 for the magnetization of the latter. The output section of the swirler 11 is in communication with the cavity of the chamber 8.

The purge water through the fitting 6 enters the vessel 4, where it separates steam and water. Water through holes 5 is directed into the cavity of housing 1, and steam from vessel 4 is directed through nozzle 7 into the conical socket 3 of the steam exhaust pipe 2, creating a vacuum in housing 1 for additional vaporization. Evaporated water of the same alkalinity enters the mixer 12, where it is mixed with the raw water passing through the device 13 for its magnetization. The mixed stream enters the snail swirler 11, where the precipitated salts (sludge) are lowered and removed through the pipe 10. At the same time, the water freed from salts is discharged from the chamber 8 through the pipe 9. The purified water is directed for further use.

Thus, in the inventive device, purge water is used for treating raw water, which improves efficiency.
