Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032]The combined cooling system of the auxiliary machine cooling water into the cooling tower of the main machine room refers to the combined cooling system in which the auxiliary machine cooling water system of the indirect air-cooled unit is merged into the cooling tower of the main machine room. This system organically combines two independent systems of main machine cooling and auxiliary machine cooling, and cancels the auxiliary machine cooling system that must be set separately for conventional units, thereby saving the structures and equipment required for the auxiliary machine cooling system and saving project investment. , saves the factory land, and reduces the operating costs of fans and other equipment in the auxiliary system that is set separately. It has the advantages of unified cooling equipment scheme, centralized arrangement...

Abstract

The invention discloses a combined cooling system and method with auxiliary machine cooling water entering a main machine intercooling tower. The system comprises a main machine cooling unit adoptinga four-row-pipe radiator or a six-row-pipe radiator and an auxiliary machine cooling unit adopting a six-row-pipe radiator. When the auxiliary machine cooling unit adopts one cooling sector, the sector is arranged in parallel to the predominant wind direction in summer; when the auxiliary machine cooling unit adopts two cooling sectors, the two cooling sectors are symmetrically arranged in the intercooling tower and are parallel to the predominant wind direction in summer; first, second and third communication valves are arranged between the main / auxiliary machine cooling units and in the auxiliary machine cooling unit; and the area of the auxiliary machine cooling unit is provided with an air inlet regulating device and an emergency cooling device. The arrangement scheme of the main / auxiliary machine cooling units, the number of the auxiliary machine cooling sectors, the relation with the wind direction, the types of the auxiliary machine cooling unit radiators, the included angle ofa main / auxiliary cooling triangle, the distance between the intercooling tower and the radiators, the communication valves and the like in the combined cooling system are specifically designed, and the operation method of the combined cooling system under severe conditions is also provided.

Description

technical field [0001] The invention belongs to the field of power generation and transformation, and in particular relates to a combined cooling system and method for incorporating cooling water of auxiliary machines into cooling towers between main machines. Background technique [0002] In recent years, for the cooling tower of indirect air-cooled generating units (hereinafter referred to as "indirect cooling tower") at home and abroad, aerodynamic field, ventilation volume, resistance and thermal characteristics of heat exchanger, and the influence of natural wind on the performance of air cooling tower have been carried out. However, there are no relevant reports on the specific layout scheme of the combined cooling system in which the cooling water of the auxiliary machine is integrated into the cooling tower in the main engine room, and the research on engineering measures to deal with unfavorable working conditions. At present, there is no operation performance of pow...
