Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0017] Vacuum energy vortex condenser, such as figure 1 As shown, it includes a vortex generating chamber 3 and a condensed water collecting chamber 5 . The vortex generating chamber 3 is a cylindrical structure made of high-hardness alloy steel, and its outer wall is wrapped with heat insulating material. The condensate water collection chamber 5 is located at the lower part of the vortex generation chamber 3, and is a cylinder with the same diameter as the vortex generation chamber. The vortex generation chamber and the condensate water collection chamber are combined into a cylinder with the same diameter. The bottom wall of the vortex generation chamber Combined with the top wall of the condensed water collection chamber to form a middle partition 9, the middle partition 9 is located at the lower part of the entire cylinder, and the middle partition 9 is a ring-s...

Abstract

The invention discloses a vacuum energy vortex steam condenser which comprises a cylindrical vortex generating chamber, wherein a condensate collecting chamber is communicated with the lower part of the vortex generating chamber, a vacuum pump is connected with the upper end of the vortex generating chamber through a vacuum pipe, a spout is formed on the side wall of the vortex generating chamber and tangential to the generatrix of the inner wall of the vortex generating chamber and used for injecting the steam exhaust from a steam turbine, a condensate pump is connected with the lower end of the condensate collecting chamber through a condensate delivery pipe, the spout is a slit penetrating the vortex generating chamber in the vertical direction, and a wedged nozzle is communicated with the spout. The vacuum energy vortex steam condenser has the advantages of simple operating principle, economic efficiency and applicability, high efficiency and energy saving, safety and reliability, simple construction and installation, convenience for operation and maintenance, stable operation, lower water consumption as compared to a wet cooling unit, higher heat efficiency as compared to an air cooling unit, and lower investment as compared to a wet cooling unit.

Description

technical field [0001] The invention relates to a device for condensing exhaust steam of a steam turbine, in particular to a vacuum energy vortex condenser. Background technique [0002] At present, the condensers of pure condensing thermal power plants include air-cooled condensers and water-cooled condensers. The principle is heat exchange, that is, the latent heat released by the liquefaction of water vapor is taken away by air or water. Its function is: the first First, establish and maintain a high degree of vacuum at the exhaust port of the steam turbine; second, condense the exhaust steam of the steam turbine into pure water to supply the boiler to complete the cycle of the steam-water system. [0003] The advantage of the air-cooled condenser is to save water, but the disadvantages are large power consumption, high investment, high plant power consumption, and low thermal efficiency; the advantages of water-cooled condensers are low plant power consumption, low inves...
