Embodiment Construction

[0048] see Figure 1 to Figure 10 As shown, a lotus condenser of the present invention is a direct air-cooled condenser, which includes two steam distribution risers 4 and a condensed water return riser 6 between the two steam distribution risers 4; The steam riser 4 and the condensate return riser 6 are connected by a plurality of inclined flat base pipes 5 to form a finned tube sheet 2; the upper part of the steam distribution riser 4 has a forward and reverse flow partition slant plate 8 to form a forward flow The flow tube bundle and the reverse flow tube bundle; the lower part of the steam distribution riser 4 is connected to the horizontal pipeline through an equal diameter elbow, and a rotatable movable joint 3 is set on the horizontal pipeline, and a ball bearing 20 is set to support the entire tube sheet. A pumping pipe 7 is provided at the top of the steam distribution standpipe for taking out gas and non-condensed gas during initial vacuuming and operation. The suc...

Abstract

The invention discloses a lotus flower type condenser and a hertz dry cooling system. The lotus flower type condenser comprises two steam distribution vertical pipes and a condensation water return vertical pipe positioned between the two steam distribution vertical pipes, wherein the steam distribution vertical pipes are connected with the condensation water return vertical pipe by a plurality of oblique flat base pipes; downstream and reversed stream separation inclined plates are arranged at the upper parts of the steam distribution vertical pipes; the lower parts of the steam distribution vertical pipes are connected with steam distribution horizontal pipes by elbows; movable joints capable of rotating are arranged on the steam distribution horizontal pipes; an air suction pipeline is arranged at the top ends of the steam distribution vertical pipes, is led and connected to the bottom of the lotus flower type condenser, and is transited by the elbows to form an air suction horizontal pipe; a movable joint capable of rotating is also arranged on the air suction horizontal pipe; the lower part of condensation water return vertical pipe is connected with a condensation water recovery horizontal pipe by the elbow; and a movable joint capable of rotating is also arranged on the condensation water recovery horizontal pipe. The hertz dry cooling system has no fan energy consumption or fan noise of an ACC (Accelerated Cooling Control) system, and has no indirect air cooling circulating water or the weight of the circulating water.

Description

【Technical field】 [0001] The invention belongs to the technical field of turning exhaust steam into condensed water by dry-type cooling of exhaust steam in a thermal (nuclear) power plant, and in particular relates to a condenser and a Hertz dry-type cooling system. 【Background technique】 [0002] For every kilowatt-hour of thermal power generation, the use of dry cooling (also known as air cooling) saves 2.5kg of water compared to wet cooling. The classic dry cooling system is divided into three types: mixed room, surface room and direct cooling. The other six cooling systems are derived from the classic three systems. [0003] Developed countries have renamed the air cooling system as drycoolingsystem. For power station cooling, heat exchangers, radiators, condensers and wet cooling and dry cooling systems are defined as follows: [0004] [0005] The significant water-saving effect of dry cooling will inevitably lead to larger system investment and higher operating ...
