Description
Technical field
The present invention relates to a kind of novel firepower condenser of power plant and its circulating cooling system, the present invention and traditional design
Condenser has the difference of essence, suitable for water-cooled generator group and air cooling turbo-generator or their spike cooling system.It is novel
The good cooling results of condenser effectively can reduce coal consumption for power generation under operation conditions on design economic pressures, reduce heat row
Into air, rivers, to reduce the influence and thermal pollution to environmental ecology.
Background technique
Thermal power plant's condenser is that steam turbine was done to the steam discharge of function to be condensed into water, with a kind of cooling equipment recycled,
Since the equipment is needed at work using largely cold resource medium, such as recirculated water, cold air, therefore, this condenser
It is designed to as surface condenser.There is following technical problem in operation in this condenser: (1) there are heat transfer resistance,
Show that there are terminal temperature differences, thus its cooling effect has certain deficiency；(2) cooling medium of this condenser puts steam
Heat out is carried in ambient enviroment, there is certain destruction to ambient enviroment ecology；(3) high for air cooling unit
Warm season limits generated output because back pressure is excessively high, also results in coal consumption for power generation and increases, thus some air cooling units violate it is water-saving
Policy adds spike cooling system to reduce back pressure, but consumes a large amount of water resource；(4) the steam thermal energy utilization rate of steam turbine
Less than 42%, unit capacity is smaller, and the efficiency that thermal energy is converted into electric energy is lower, and the useless heat more than 60% is all discharged into
It is wasted in environment.
In order to solve the above-mentioned technical problem, the present invention propose thermal power plant's Condenser Design at a kind of direct-contact type condenser simultaneously
Using corresponding circulating cooling system.
Summary of the invention
By taking air cooling unit as an example, air cooling unit be steam is condensed into water using cold air as cooling medium, but
At summer, cooling system is not able to satisfy safety economy production, thus some units increase again it is a set of small-sized as used in water cooling
The circulating water cooling system of unit, for steam turbine part steam discharge is condensed into water, to mitigate the load of Air-Cooling Island, this undoubtedly increases
The burden that water resource utilizes is added.The present invention proposes that a kind of device systems and method can solve these technical problems, that is, newly establishes
Direct-contact type condenser and its circulating cooling system, cooling working medium is using condensed water itself or uses soft water as cooling water source, this
A little water sources can reuse, and therefore, be not required to consume a large amount of water resource, when direct-contact type condenser works, cooling medium and quilt
Cooling steam directly contacts, and heat transfer resistance is not present, and therefore, terminal temperature difference, cooling effect is also not present in performance in the technical effect
Fruit is more ideal.
If mixing condenser described above is designed sufficiently large, conventional water cooling firepower at present can be theoretically substituted completely
The surface condenser of generating set, to solve at one stroke all.
The present invention is achieved through the following technical solutions:
A kind of novel firepower condenser of power plant and its circulating cooling system are by direct-contact type condenser, one or more condensation
Water pump, one or more refrigeration unit, sprayer and its cooling line system constitute a closed-loop system, wherein hybrid condensing
Device size is designed as the several times or decades of times size of steam discharge quality volume, can be arbitrary shape, in the side of condenser closed container
Middle face is equipped with steam inlet, steam cooling zone, on-condensible gas cooling zone is equipped with inside condenser closed container, in condensing
Device closed container highest point is equipped with vacuumizing and exhausting mouth, direct-contact type condenser bottom is condensed water reservoir, is commonly called as hot well.Heat
Well is connected by pipe valve with condensate pump, and the condensate pump is connected by pipe valve with refrigeration unit, and refrigeration unit is being dropped
Low-temperature condensate after temperature transfers to the spray cooling system inside condenser by pipe valve, provides endlessly circulating cooling use
Water, the Municipal Sewage for Circulating form subparticle droplet after nebulizer and arrange full of entire condenser container and steam turbine
Steam out directly contacts and carries out condensation heat, achievees the purpose that condensed steam, the evacuated exhaust outlet of incondensable gas
It is taken away by vacuum pump.
Refrigeration unit described above is preferably BrLi chiller, and function is freezed using thermal energy, condensed water
A part cooling after be used as work cooling water, while again using another part condensed water be used as the cooling water of refrigeration unit, use
To recycle the consumed useless heat that freezes.

Specific embodiment
In order to better understand the technical solution of the utility model condenser, using 1 300MW unit as embodiment.Below with reference to
The embodiment that attached drawing the present invention is described in detail provides:
Shown in referring to Fig.1, common thermal power plant surface-type gas trap includes: that turbine discharge access port, surface-type are cold
But element (being equipped with recirculated cooling water water inlet, discharge outlet and into and out of water chamber), hot well, condensate pump, pumped vacuum systems and vacuum
Pump etc..Common gas trap is taken away the latent heat of vaporization that turbine discharge condensation is released by recirculated water and is discharged into environment, disappears
It has consumed a large amount of water resource and has had certain destruction, i.e. thermal pollution to ambient enviroment.To solve this technical problem, table
Face formula Condenser Design is at direct-contact type condenser, as shown in Figure 2 --- direct-contact type condenser by arbitrary shape closed container, one
Platform or more condensate pumps, one or more refrigeration unit, sprayer and its cooling line system constitute a closed-loop system,
