Condensed water circulating cooling energy-conserving and emission-cutting technology

Abstract

The invention discloses a condensate water circulation cooling energy-saving emission-reduction technology. Condensate water as well as sprayed and atomized steam water are adopted to be directly mixed with heat exchange condensation at a high temperature end in the exhaust orifice of a steam turbine; the condensate water after heat exchange condensation flows into a condensate water collection well, is pumped into the hot pump of a water source by a condensate water pump, returned to the high temperature end in the exhaust orifice for spraying and atomizing to form cooling circulation after being cooled by the hot pump of the water source; the afterheat is transferred to a boiler simultaneously when being cooled by the hot pump of the water source to form afterheat circulation for the water consumption of water or other different water qualities. The technology has a plurality of functions of energy saving, water saving, environment protection, running cost reducing, efficiency improving, etc. The technology realizes the cooling circulation and afterheat circulation in particular and gains new breakthrough on the aspects of improving the heat exchange effect, increasing the vacuity of a machine set, improving the output, the afterheat recycling and utilizing as well as energy saving and emission reducting; besides, the environment protection and the social benefit are remarkable.

Description

Technical field [0001] The invention relates to a condensed water circulating cooling energy saving and emission reduction technology, which is mainly used in the field of thermal power. Background technique [0002] Lack of water resources, energy depletion and serious environmental pollution are common phenomena at present. Water, energy and environmental issues in the 21st century are issues of universal concern to the world. In recent years, with the rapid development of modern science and technology, people pay more and more attention to the low-temperature heat energy that has not been effectively used until now. Among the low-temperature heat energy that has not been effectively used, the low-temperature heat energy of thermal power plants is one of them. [0003] Circulating water cooling towers in the iconic buildings of thermal power plants swallow clouds and fog all the year round, and most of the heat is discharged into the atmosphere through the cooling towers. This ...
