Abstract

The invention discloses a combined pump room arrangement method, relating to the technical field of nuclear power. The invention solves the problem that the prior art lacks a compact and efficient arrangement method for reasonably arranging devices in a combined pump room. The embodiment of the invention provides a combined pump room arrangement method, wherein the combined pump room comprises a pump region and a filtering device region; the pump region comprises an important house service pump sump; the important house service pump sump is used for arranging important house service pumps, drum mesh backwash pumps and fire service pumps with higher safety degree requirements; the outer side of the important house service pump sump is used for arranging water circulating pumps and seawaterlift pumps with lower safety degree requirements; and the filtering device region is used for arranging steel gates, a coarse grating, chlorination pipe devices, a fine grating, cleaners and drum meshes. The combined pump room arrangement method provided by the embodiment of the invention is widely applied to nuclear power generating units and the like.

Description

technical field [0001] The invention relates to the technical field of nuclear power, in particular to a method for arranging a combined pump room. Background technique [0002] The combined pump house is a sub-item with high process design standards and complex civil design, and its status in nuclear power plants is second only to nuclear island and conventional island powerhouses. The combined pump house provides sufficient cooling water to both the conventional island power building and the nuclear island power building to ensure the normal operation of the nuclear power plant and the safe shutdown in case of an accident. Its main functions include: [0003] (1) Provide necessary cooling water to the condenser and auxiliary cooling water system of the turbogenerator unit, and this part of the function is completed by the circulating water (CRF) system; [0004] (2) Transfer the heat load collected by the equipment cooling water system in the nuclear island powerhouse to ...
