Description
Technical field
The utility model relates to a kind of condenser atomizing humidifying cooling device in the power station direct air-cooling system, and this device can improve the operational efficiency of the air cooling tubes condenser of summer high temperature period.
Technical background
The coal resources of China three northern areas of China are abundanter, but because water resources shortage has limited local construction of fire and electricity.Direct air cooling system has good water-saving result because of it, has obtained extensive promotion and application in recent years.Along with the aggravation of greenhouse effects, the problem that the feasible Direct Air-cooled Unit that puts into operation in recent years of global warming is exerted oneself and is obstructed, can not completely sends out at summer high temperature ubiquity in season.Because the cooling capacity of Direct Air-cooled Unit depends on the dry-bulb temperature that enters the air cooler air, summer, higher air themperature can cause the air cooler cooling capacity to descend, reduce the unit vacuum, make actual the exerting oneself of unit be lower than design rating, very big to the economy and the Safety Effect of unit.Therefore, taking the necessary measure of aestivating to reduce the inlet air temperature of air cooler, strengthen the cooling effect of air cooler, is to solve Direct Air-cooled Unit to exert oneself summer and to be obstructed, and improves one of effective way of unit economy and security.
Because direct air cooling system is directly to utilize dry air to cool off, so exerting oneself of Direct Air-cooled Unit depended on the air dry-bulb temperature that enters air cooler.Use for reference the experimental result of the atomizing conditioning Tower of chemical industry and cement industry, adopt the atomizing humidifying method can reduce the temperature of air cooler intake air effectively, significantly improve the cooling capacity of air cooler in the air cooler import.Its operation principle is: water forms the droplet of certain particle diameter through nozzle atomization, droplet fully mixes and evaporation rapidly with air in motion process, because the latent heat of vaporization of water is bigger, can absorb airborne heat in a large number during the water evaporation, thereby reduce the dry-bulb temperature of air, the humid air after will lowering the temperature is then delivered to air cooling heat radiator, reaches the operational efficiency that improves air cooling tubes condenser, reduce unit operation pressure, increase the purpose of unit output.
Atomizing humidifying cooling device adopts power plant's demineralized water as the water source, though need during work to consume a certain amount of demineralized water and increase investment and operating cost, but improve the economic benefit of being brought with respect to unit output, the increase of its expense is less relatively, and economic benefit is still more considerable.
At present, known atomizing humidifying cooling device all is that design and installation is under the blower fan lifting beam, jet hole is sprayed downwards, such layout has produced two problems: if nozzle is arranged in the fan bridge both sides, though water spraying direction is for adding contrary spray to spray, but, influence cooling-down effect because the fine droplet evaporation that nozzle near the blower fan exit, makes atomizing form is insufficient; If the position of arrangement of nozzles is increased to blower fan lifting beam lower end, adopt a nozzle, though evaporation process prolongs to some extent, but because water spraying direction only is contrary spray, its atomizing cool effect does not increase yet, and this kind structure need be installed in the blower fan lifting beam under, will influence mobile after the fan drive device lifting, therefore need dismounting atomizing humidifying cooling device before the maintenance process, waste time and energy, very inconvenient.
