Description
[technical field]
The utility model belongs to generating set cooling technology field.More specifically, the utility model relates to the circulating-water in thermal power plant system that has function of recovering waste heat.
[background technology]
Along with the enforcement of country about " energy-saving and emission-reduction " and fired power generating unit " go up big press little " policy, be that the concentrated supply of heating in the city system of thermal source is more general in China " three Norths " area to be equipped with the draw gas cogeneration plant of condensing-type unit of good economy performance, big capacity that load performance is strong.And in recent years, cogeneration plant is aided with absorption heat pump and reclaims the recirculated water waste heat, realizes that the transformation of energy efficiency has become irreversible gesture.But the cooling tower that brings thus freezes, heat pump performance guarantees and problem such as recirculated water optimization operation is also more outstanding.
Because winter severe cold phase heat load is big, the steam turbine displacement is considerably less, and cooling tower is crossed the low problem that freezes because of thermal load and perplexed power plant always.Usually cogeneration plant adopts put into operation a water circulating pump even the operation of low speed low discharge at this problem, and cooling tower only adopts inner ring or outer ring operation simultaneously.But behind absorption heat pump recovery section recirculated water waste heat, the cooling tower thermal load is lower, and the cooling tower filler layer freezes and can't avoid.After heat pump reclaimed a unit waste heat fully, the cooling tower filler layer can not freeze because of anhydrous, but freezed and be inevitable in the pond.The power plant that also has adds abat-vent around the cooling tower and realizes cooling tower antifreezing, but causes in the higher period of temperature that the unit back pressure is higher, economy descends.
Another one contradiction is that the height of heat pump outlet circulating water temperature is bigger to heat pump manufacturing cost and performance impact.Cogeneration plant all adopts raising outgoing condensate water method of temperature to guarantee heat pump performance at present.But under separate unit water circulating pump operating condition, heat pump outlet recirculated water can not be higher.Otherwise the steam turbine economy descends more.Concerning the cogeneration plant that is equipped with two identical units, usually as far as possible to having the heating of drawing gas of waste heat recovery unit, to reduce to improve the adverse effect that circulating water temperature brings unit economy more.
Separate unit water circulating pump operation brings the another one problem to be, condenser cooling tube internal cause water velocity is lower and easy fouling influence heat exchange effect and unit economy, and needs adopt the glueballs cleaning relatively frequently.After heat pump was introduced, glueballs cleaning operation and effect may affect adversely, and took all factors into consideration when needing system's design.
And conventional circulating-water in thermal power plant system can't guarantee the outgoing condensate water temperature constant, how to regulate by the circulation design and running, guarantees heat pump entrance circulating water temperature at design level, and is significant equally.
In order to guarantee the security of heat supply, present large-scale cogeneration plant arranges two units usually at least, corresponding two cooling towers.Some power plant freeze for avoiding the cooling tower filler layer, adopt double tower unification operational mode, but the phenomenon that freezes appear in the cooling tower tower basin water that do not move this moment, if ice cube enters the damage that will cause impeller or blade in the ebullator.In addition, after tower basin freezes, when needing, unit can't put into operation fast and directly.And after increasing absorption heat pump recovery recirculated water waste heat, after advancing heat pump, the recirculated water that the direct employing of most power plant will be recovered the waste heat unit returns pond of cooling tower or corresponding water circulating pump inlet duct, comprehensive inadequately to genset and the consideration of source pump operation coupling factor, when heat pump only can reclaim recirculated water fraction waste heat, unit safety operation is constituted a threat to; When heat pump can reclaim most recirculated water waste heat, can't solve the cooling tower filler layer problem that freezes; When heat pump reclaims the recirculated water waste heat fully, can't solve the antifreeze problem of pond of cooling tower of stopping using again.The cogeneration plant that has is in order to solve water tower packing layer and the pond problem that freezes, and the sacrificial section waste heat is specifically designed to antifreezely, causes the waste of the energy.
In addition, during the winter operation, cogeneration plant usually only needs water circulating pump of operation can guarantee that unit works under economic back pressure, when needs carry out increasing a water circulating pump operation when glueballs cleans again to condenser, cleans and becomes a pump operating cycle again after finishing.But the introducing of heat pump is cleaned to condenser ball and to be brought difficulty, perhaps because the cold water in pond enters system and causes heat pump entrance circulating water temperature well below design load, influences heat pump performance even can't normally move.
Therefore, how to realize the utilization each other of resource between unit, design a kind of flexible operation, efficient height, can under various operating modes, guarantee the circulation that has function of recovering waste heat and the operation control method thereof of unit safety operation to have very important meaning again.
