Abstract
The present invention relates to a kind of residual neat recovering system of double condensers, involved system and device is made of steam turbine, generator, absorption heat pump, level-one condenser, two level condenser, plate heat exchanger, flow regulator, various water pumps and pipeline.The present invention is by by absorption heat pump and two groups of rational united applications of condenser machine, intermediary's water flows through level-one condenser and absorbs exhaust steam residual heat, as the low-temperature heat source of absorption heat pump, the power source of the stage casing steam extraction of steam turbine as vapor-water heat exchanger and absorption heat pump.Absorption heat pump and vapor-water heat exchanger successively act as primary net return water and are heated, and the primary water supply after heating is input to user side.Simultaneously flow through two level condenser tube side Absorption by Sea Water part flow through two level condenser shell intermediary's water thermal energy, be reached for the purpose of intermediary water cooling cooling.
Description
Technical field
The invention belongs to improve efficiency of energy utilization field, it is related to a kind of residual neat recovering system of double condensers.
Background technology
The current central heating in China mainly uses cogeneration of heat and power form.Coastal waters, nearly lake, Jin He steam power plants, often through sea
Water, river or lake water are directly entered condenser and are condensed to exhaust steam in steam turbine, can effectively reduce in this way steam power plant's construction at
This.For generating electricity, low-grade heat source is but needed through river, river, lake, seawater discharge steam power plant's high-grade heat source.River, river, lake, seawater
In possess a large amount of minerals, can heavy corrosion heating conveyance conduit and heating building heating equipment, therefore one can not be used as
Secondary net heating water, this partial heat discharge in vain for a long time.
Invention content
For the steam power plant that river, river, lake, seawater cool down, although the surface water containing a large amount of minerals contains a large amount of low temperature
Heat can not but be used as primary the problem of netting water supply, carry out technological transformation, its waste heat be allow to be recovered.Steam turbine discharge simultaneously
Steam exhaust in contain a large amount of latent heats of vaporization, the problem of can not all being recycled using absorption heat pump, the present invention provides a kind of double
The residual neat recovering system of condenser.
The technical solution adopted in the present invention is：
1, the steam extraction of steam turbine stage casing is divided into two parts, and a part of stage casing steam extraction is input to absorption heat pump, as absorption
The power source of heat pump unit participates in heat exchange；The steam extraction of another part stage casing is input to steam water heat exchanger, to having passed through absorption heat pump
The primary net of unit, which supplies water, carries out two level heating；Primary net return water flows through in absorption heat pump, and a part comes from level-one condenser
The condensed water with Low Temperature Thermal as low-temperature heat source, be that low-temperature primary net returns with the stage casing steam extraction collective effect from steam turbine
Water is heated, and the primary net return water after heating is input to steam water heat exchanger, carries out two level heating, and the high-temperature water after heating is made
It is input to big temperature difference heating user side once to net water supply, completes cycle；
2, one condenser is installed again, two solidifying after the condenser by script using earth's surfaces water coolings such as river, river, lake, seas
Cooling water is injected among vapour device, the condenser newly installed is cooled down using seawater, because condenser internal pipeline is that titanium alloy is anticorrosive,
Shell side is that carbon steel is not anticorrosive, so seawater walks condenser tube side, cooling water walks shell side.
3, the low-temperature steam exhaust after driving steam turbine acting is cooled down by level-one condenser condenses, and carries the condensed water of Low Temperature Thermal
It is divided into two parts, as absorption heat pump low-temperature heat source, second part is limited to absorption heat pump recycling ability and asks for first part
Topic, is cooled down using two level condenser, discharges heat.
The beneficial effects of the invention are as follows：
Using double condenser structures, seawater only flows through the tube side of two level condenser, and tube side is titanium material, will not be by sea
Aqueous corrosion acts on.By double condenser structures, seawater is isolated with absorption type heat pump assembly, prevent seawater to heat pump unit and its
The corrosiveness of his system unit greatly improves the stability of system work.

Specific implementation mode
In steam power plant, steam turbine (1) high temperature steam drive generator (2) power generation；Then by the stage casing of steam turbine (1)
Steam extraction is divided into two parts, and a part is input to steam water heat exchanger (4), to being supplied by the primary net of absorption heat pump (3) unit
Water is heated；Another part is transported to absorption heat pump (3), and the power source participation as absorption heat pump (3) unit is changed
Heat；
Steam exhaust in steam turbine (3) is discharged into level-one condenser (5), and condensed water, condensed water are condensed into after exchanging heat with condensed water
It is divided into two parts, part input absorption heat pump (3), the Low Temperature Thermal as absorption heat pump (3) unit after exchanging heat with steam exhaust
Source；Another part is input in the shell side of two level condenser (6), is carried out with the low temperature seawater for flowing through two level condenser (6) tube side
Heat exchange cooling, condensate return (9) after cooling and the low temperature cold condensate return water (9) after absorption heat pump (3) heat exchange are mixed
Level-one condenser (5) is flowed into after conjunction.
In absorption heat pump (3) unit, a part of stage casing steam extraction from steam turbine (1) passes through one as power source
Condensed water after grade condenser (5) exchanges heat is discharged (8) as low-temperature heat source, and collective effect is to carry out arrogant temperature difference heating user side
Primary net return water (10) exchanges heat, and the primary net water supply (11) after heat exchange is input to steam water heat exchanger (4) progress two level and adds
Heat is finally delivered to big temperature difference heating user side (7).
