Technical field
It is unconventional clammy with air cooling apparatus engineering field that the invention belongs to steam power plant's steam exhaust, and in particular to one kind is based on refrigeration
Mode makes steam exhaust be converted into the device of condensed water.
Background technique
No matter its fuel supplies the differences such as form such as coal, gas, oil, rubbish, nuclear material for traditional steam power plant, distributes electricity
Steam exhaust will use cooling water temperature in cooling tower, be changed into after the condensed water of suitable temperature for reusing.This is steam power plant
The inevitable requirement of operating condition.
Cooled down by traditional cooling tower to steam exhaust, because it uses open system mode all there can be a large amount of water with water vapour every year
Form is dispersed into atmosphere, this consumption for general steam power plant also in ten-million-ton scale, at present cooling water per ton
Reason expense calculates, this is also a no small consumption.And no small pressure also is brought to power plant's addressing, operation because water consume is larger
Power.Area especially less in water resource.

(2) turbine back pressure luffing is big, and back pressure changes with air temperature variations.(3) vacuum system is huge.
The advantages of Harmon formula indirect air cooling system is that (1) saves power plant's electricity consumption, and equipment is few, cooling water system and boiler circuit
It separates, the two water quality can be by respective requirement control.(2) cooling water inflow is according to seasonal adjustment.(3) air cooling heat radiator is in Ta Neibu
It sets, substantially not by the ability of its on-load of adverse weather conditions.
The disadvantage is that the land occupation of (1) air cooling tower is big, capital expenditure big (2) power generation coal is about 105% more than conventional wet type cooling unit；(3)
It needs to exchange heat and belong to surface heat exchanging twice in system, declines power plant's entirety thermal efficiency.
The advantages of Hai Leshi direct-contact type condenser indirect air cooling system is that (1) is run with the low pressure water system of micro-positive pressure, easily
, can be mating with middle back pressure turbine in manipulation, (2) cooling system consumption power is low, and occupied area is moderate, invests lower.
The disadvantage is that (1) system anti-freezing property is poor, (2) air cooling heat radiator is arranged outside tower vulnerable to its bringing onto load energy of big wind effect
Power (3) device systems are complicated, and (4) cooling water is directly contacted with exhaust steam in steam turbine.
