Description

This invention relates to a power system, in particular to steam turbine condensers.

The purpose of the invention is to increase efficiency.

The drawing shows a diagram of the surface condenser.

The surface condenser comprises a housing 1 with a bundle of heat-exchange tubes 2 connected inside the inlet and outlet water chambers 3 and 4, the nozzles 5 and 6 of the steam and cooling water supply, the nozzles 7 and 8 of the condensate and heated water, and an ejector 9 for suction of gases At least from the inlet water chamber 3, the Condenser is additionally equipped with an injector 10 disposed in the outlet chamber 4, the discharge nozzle of which is placed coaxially with the outlet 8 of the heated water. The output section of the pipe 8 is made V - shaped with the formation of a hydraulic seal. The heat exchanger tube bundle 2 is placed with a slope upward along the water movement. Capacitor,. in addition, it contains a water level regulator II, once again in the inlet chamber 3,

The device works as follows.

The cooling water enters the inlet chamber 3 through the pipe 6 and further, the passage through the pipes 2 of the heat exchange beam enters the output chamber 4, from where it is drained through the pipe 8, made V-shaped to form a water seal. The steam enters the condenser corus 1 through the pipe 5, and the condenser on the pipes 2 of the heat exchange beam is discharged through the pipe 7. The water level in the inlet chamber 3 through the regulator 11 is maintained at the level of placement of the pipes 2, and pipes to the outlet chamber 4. The vacuum in the upper part of the chamber 3 is maintained by the ejector 9, which ensures that the water receives heat from the steam. The suction of gases from the upper part of the output chamber I is carried out by the injector 10, the discharge nozzle of which is placed coaxially with the nozzle 8

removal of heated water, which contributes to the accelerated discharge of water. The implementation of the nozzle 8 V - shaped with. The formation of a hydraulic lock, which has a height h Hume, provides

reliable continuous operation of water discharge at any vacuum in the chamber 3.
