Description
Technical field
The utility model relates to indirect air cooling technical field, particularly relates to a kind of tower body draft adjusting device and indirect air cooling system.
Background technology
At present, indirect air cooling system has been widely used in northern area thermal power plant.Since running from indirect air cooling system, preventing freeze in winter problem governs a performance for cooling system safety and stability advantage always.And the probability that freezing accident occurs remains high, innovation need be deepened further in conjunction with cooling tower structure form while running later stage antifreeze strategy emphatically.
The indirect cooling tower of gravity-flow ventilation is in the winter time under operating mode, the sector quantity that generally comes into operation is few, and, also less for cost consideration gravity-flow ventilation indirect cooling tower sector division numbers, this brings trouble to controlling radiator amount of cooling water flexibly winter, cause and adopt the section of the coming into operation amount of N+1 to do the following two kinds of disastrous effects of improvements antifreeze logic generation: first, improvements section temperature is high causes overall circulation cooling water temperature drift, unfavorable to economy, simultaneously, other cooling section can according to back pressure rise situation continued increase cooling capacity, to antifreeze unfavorable; The second, in well-known tower there is lifting effect in the high draft to the indirect cooling tower of gravity-flow ventilation of lower curtate environment temperature, and the thermal current of cooling tower can be formed " plume " under more extraneous meteorological condition.
When calm and air is without appearance of low altitude inversion layers, plume relies on the kinetic energy of cooling tower outlet ascending air, and can vertically rise certain altitude.This lifting height is the rising height having height scope to add outward at air duct, also produce draft to the air-flow in cooling tower, in tower, the draft of lower curtate environment temperature more high tower is stronger, selects N+1 pattern, continue the ventilation adding tower to a certain extent, cause anti-freezing pressure equally.
As under winter condition, cooler ventilation of how controlling well just seems particularly important.The improvements pattern of general employing N+1 is exactly be that the closedown shutter that doing has appearred in low temperature condition carries out the measure heated up that gets warm again after a cold spell from definition.And often occurring that antifreeze improvements section not yet terminates, other target phase also occurs that low temperature needs the operation that promptly gets warm again after a cold spell, and causes improvements hop count amount to increase, and in tower, temperature continues to rise.
In sum; indirect air cooling system of the prior art can not regulate the draft of cooling tower; cause when temperature is low; shutter aperture is less; cooler unit are wind speed is larger, and anti-freezing pressure becomes large, and along with after the antifreeze logical action of proterctive equipment security consideration; the above-mentioned trend final unavoidable unit high back pressure that also grows in intensity runs, and even occurs the possibility of shutting down.
