Description

The invention relates to energy and can be used in steam turbine condensers.

The aim of the invention is to increase the efficiency of a capacitor by expanding its functionality.

FIG. 1 shows a capacitor, a transverse section; in fig. 2 - mixing compartment; in fig. 3 - capacitor, longitudinal section.

The combined condenser includes a housing 1 with a steam supply pipe 2 and a condensate drain pipe 3, a condensate collector made of two water-isolated sections 4 and 5, surface compartments with tube bundles 6 placed in them (Fig. 1), a mixing compartment between the surface compartments , including a water distribution device, made in the form of a zigzag shape perforated in the lower part of the collector 7 in horizontal section, and a branch pipe 8 of cooling water supply connected to the collector 7 ( 2) placed under the mixing compartment along the entire body 1 section 5 of the condensate collection section of the mixing section with its own pipeline 9 for draining heated water, while section 5 is provided with a vertical plate 10 (Fig. 3).

The condenser is equipped with nozzles 11 (Fig. 1) for non-condensable gases withdrawn placed on the side walls of the housing 1 along the surface compartments, and a collector 12 for withdrawing the vapor-air mixture (PVA) from the mixing compartment placed along its axis.

The combined capacitor works as follows.

The vapor enters the housing 1 through the nozzle 2 and condenses on the surfaces of the tube bundles 6, the surface compartment. The condensate of the surface compartment enters the corresponding sections 4 of the condensate collector and is discharged from the condenser.

0 Discharge of non-condensable gases is carried out through nozzles 11. Steam enters the mixing chamber from two sides. Cooling water (chemically cleaned, network, etc.) of the mixing chamber post, falls into the condenser through the collector 7 and heats up, drains down to form a curtain of thin jets having a zigzag shape (in horizontal section). In this case, part of the steam condenses on the water jets. The water with a small part is heated

0 condensate from the mixing compartment is discharged through line 9 and the condenser. Plate 10, mounted above the suction pipe in section 5, prevents the occurrence of circular movement of water in it. Drainage of PVA from the mixing Chamber is carried out through the collector 12.

Since the movement of steam to the mixing compartment is carried out from two sides, the cooling water 0 of the mixing compartment does not splash, and its effective heating and deaeration are carried out. Thus, the overall performance of the capacitor is improved.
