Tower type direct air cooling condenser

Abstract

The invention relates to the technical field of power station air-cooling systems, and particularly discloses a tower type direct air-cooling condenser. The tower type direct air-cooling condenser comprises a steam engine room, a steam exhaust pipeline, a supporting column, a draught fan set, an air-cooling platform support, a heat sink pipe bundle, a steam distribution pipe and a tower type wind break wall. Exhausted steam of a steam turbine in the steam engine room is exhausted into the heat sink pipe bundle through the steam exhaust pipeline and the steam distribution pipe in sequence, the steam distribution pipe is communicated with the upper end of the heat sink pipe bundle, the heat sink pipe bundle, the draught fan set and the tower type wind break wall are arranged on the air-cooling platform support, the draught fan set is located below the heat sink pipe bundle, the tower type wind break wall is located on the periphery of the heat sink pipe bundle, the size of an opening in the upper end of the tower type wind break wall is smaller than that of an opening in the lower end of the tower type wind break wall, the position of the opening in the upper end is higher than the position of the upper end of the steam distribution pipe, and the air-cooling platform support is erected on the supporting column; and according to the condenser, the influence of exterior environment wind on the direct air-cooling condenser can be effectively reduced, and meanwhile the power consumption of draught fans can be reduced.

Description

technical field [0001] The invention relates to the technical field of power station air-cooling systems, in particular to a tower-type direct air-cooling condenser. Background technique [0002] As the country pays more and more attention to the protection of fresh water resources, the air-cooling system of power stations has gradually been widely used in water-scarce areas in my country. The air-cooling system of power stations is currently divided into two types: direct air-cooling system and indirect air-cooling system. The direct air-cooling system has the characteristics of simple system, good antifreeze performance, small footprint, flexible adjustment, low initial investment, and short construction period. application. The direct air cooling system is also called the air-cooled condenser (ACC). The exhaust steam of the steam turbine is directly cooled and condensed by the air in the closed radiator. The cooling air is driven by a mechanical axial flow fan. The fan,...
