Evaporative condensers for peak cooling in power plants

Abstract

The invention discloses an evaporative-type condenser for peak cooling of a power plant. The evaporative-type condenser comprises a condenser shell, an air inlet is arranged on each of two opposite side walls of the condenser shell, a filler-coiler composite-type evaporative cooling unit is arranged in the condenser shell, vertical-pipe-type indirect evaporative cooling units are symmetrically arranged on the left side and the right side of the filler-coiler composite-type evaporative cooling unit, an air outlet a is arranged on the corresponding top wall of the condenser shell above the filler-coiler composite-type evaporative cooling unit, and an air outlet b is arranged on the corresponding top wall of the condenser shell above each of the vertical-pipe-type indirect evaporative cooling unit. The evaporative-type condenser is high in condensing efficiency, a certain affluence amount is provided for high-temperature strong-air running of an air cooling system of the power plant in summer, running effect of an air cooling unit is better, and huge economic benefit is brought to the power plant.

Description

technical field [0001] The invention belongs to the technical field of exhaust steam condensation in power plants, and in particular relates to an evaporative condenser for power plant peak cooling. Background technique [0002] Northwest China is "rich in coal and lacks water", so a large number of power plants use direct air cooling systems to condense and cool the exhaust steam of steam turbines. The direct air-cooling system of the power plant is that the exhaust steam of the steam turbine is introduced into the steel radiator of the air-cooled condenser through the pipeline, and is directly cooled by the ambient air into condensed water, and then recycled. [0003] During the high temperature period in summer, the heat exchange temperature difference of the air-cooled condenser decreases, and the heat exchange capacity decreases, and dust, catkins and other pollutants cause the surface of the condenser to be dirty, which affects the heat exchange, and the unit is forced...

AI Technical Summary

Problems solved by technology

[0003] During the high temperature period in summer, the heat exchange temperature difference of the air-cooled condenser decreases, and the heat exchange capacity decreases, and dust, catkins and other pollutants cause the surface of the condenser to be dirty, which affects the heat exchange, and the unit is forced to reduce the load to operate. Huge economic losses to power plants

[0004] At present, power plants use evaporative condensers to divert part of the exhaust steam for condensation, but affected by environmental factors, the condensation efficiency of evaporative condensers is limited. If the temperature of the air entering the evaporative condenser and the temperature of spray water can be adjusted If it is lowered, the condensation efficiency of the evaporative condenser can be improved, and it will play a greater role in the operation of the air cooling system of the power plant during the high temperature period in summer
