Abstract

The invention relates to the technical field of power plant air cooling, in particular to a power plant air cooling island capacity increasing switching system. The power plant air cooling island capacity increasing switching system comprises a first air cooling unit, a second air cooling unit and two columns of capacity increasing air cooling condensers, dead steam inlets of the capacity increasing air cooling condensers communicate with second dead steam pipes through capacity increasing dead steam pipes, condensed water outlets of the capacity increasing air cooling condensers communicate with second condensed water pipes through capacity increasing condensed water pipes, and vacuumizing outlets of the capacity increasing air cooling condensers communicate with second vacuumizing pipes through capacity increasing vacuumizing pipes. Dead steam inlets of switching air cooling condensers communicate with first dead steam pipes through dead steam switching pipes, condensed water outlets of the switching air cooling condensers communicate with first condensed water pipes through condensed water switching pipes, and vacuumizing outlets of the switching air cooling condensers communicate with first vacuumizing pipes through vacuumizing switching pipes. The improvement measure of capacity increasing (namely heat exchange area increasing) of an existing air cooling unit is adopted, so that the operation back pressure of a steam turbine unit is reduced, and the operation economical efficiency of a power plant unit is improved.

Description

technical field [0001] The invention relates to the technical field of power plant air cooling, in particular to a power plant air cooling island capacity increase switching system. Background technique [0002] The air cooling technology of power plants is roughly divided into two forms, one is direct air cooling, and the other is indirect air cooling. Direct air cooling means that the exhaust steam of the steam turbine is directly cooled by air, and heat exchange is performed between air and steam. The dry cooling of the air cooling unit does not require a large amount of cooling water, and the dry cooling unit of the power plant saves more than 60% of water than the wet cooling unit. Therefore, in the north of our country where there is more coal and less water, there are many air-cooled power plants. [0003] The main task of the direct air cooling system of the power plant is to condense the exhaust steam of the steam turbine into condensed water through the ambient a...
