Abstract
The invention discloses a steam condenser type seawater desalting device with a steam turbine generator unit, which comprises a boiler, a steam turbine and a low-temperature multiple effect evaporation seawater desalting device, wherein the steam turbine is connected with the boiler; the steam exhaust output of the steam turbine is connected with the boiler through a steam condenser and a circulating water pump; and the condenser is a first effect evaporator of the low-temperature multiple effect evaporation seawater desalting device. The steam exhaust discharged by the steam turbine generator is used as the heat source of the low-temperature multiple effect evaporation seawater (brackish water) desalting device, i.e. the first effect evaporator of the low-temperature multiple effect evaporation seawater (brackish water) desalting device is substituted for the condenser of a power generating system, the steam exhaust discharged by the steam turbine is condensed into water and cyclically used, thus the costs of power generation and seawater desalination are greatly reduced, and the energy utilization rate of the unit is obviously improved.
Description
Technical field
The present invention relates to a kind of sea water desalinating plant, especially a kind of electric turbine group condenser formula sea water desalinating plant that can effectively utilize heat energy, reduce the sea water desaltination cost.
Background technology
At present, the structure of low-temperature multi-effect evaporation desalination device is more, and multiple-effect horizontal tube falling film evaporation device or the like is arranged.Multiple-effect horizontal tube falling film evaporation device by vaporizer, separator, preheater, condenser, coagulate parts such as water pot, recycle pump and form.Seawater (brackish water) feed liquid is through liquid spraying or liquid distributor, on the horizontal heat exchange tube bundle in the uniformly distributing auto levelizer, under gravity, vacuum induced and air-flow effect, becoming evenly membranaceous flows from top to bottom, partially liq is by heat transfer tube heating vaporization in flowing, and formed vapour-liquid is through fully separating, and steam enters down 1st effective evaporator as heating medium, steam is fresh water through the formed water of condensation of heat exchange, collects as freshwater product by imitating; Liquid (strong brine) after concentrating drains into down the top or the bottom of 1st effective evaporator, and in the end 1st effective evaporator converges and discharges.The used steam of existing multiple-effect horizontal tube falling film evaporation device is supplied with by the special boiler (boiler, solar heat collector) that is provided with, and need expend a large amount of energy, and the sea water desaltination cost is higher.
Existing fiery (heat) power plant mainly contains the Steam Turbine of condensing-type and two kinds of operation scheme of back pressure type, and system's main composition and working process are: boiler produces high pressure steam, and the acting of high pressure steam pushing turbine drives generator work; For the back pressure unit, the steam of finishing acting in steam turbine also has higher pressure, drain into steam pipe system and be used for process requirements or heat supply, but if thermal load will cause extremely adverse influence to unit operation unstable; For the condensing unit or take out with fixed attention unit, the steam of finishing merit is disposed to condenser as exhaust steam, and exhaust steam heat release in condenser back of condensing is transported to recycle behind the unit for treating water by water circulating pump.The heat that exhaust steam is discharged in condenser (account for the very big part of fuel energy, even more than the 50%) medium that is cooled (air or water) is discharged in the environment and wastes.
Summary of the invention
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, a kind of electric turbine group condenser formula sea water desalinating plant that can effectively utilize heat energy, reduce the sea water desaltination cost to be provided.
Technical solution of the present invention is: a kind of electric turbine group condenser formula sea water desalinating plant, the steam turbine that boiler is arranged and join with boiler, the exhaust steam output of steam turbine is joined by condenser, water circulating pump and boiler, it is characterized in that: be provided with low-temperature multi-effect evaporation desalination device, described condenser is first single-effect evaporator of low-temperature multi-effect evaporation desalination device.
Described low-temperature multi-effect evaporation desalination device is a multiple-effect horizontal tube falling film evaporation device.
Seawater ingress at described multiple-effect horizontal tube falling film evaporation device is provided with the seawater preheating condenser.
The present invention is the thermal source that evaporates seawater (brackish water) desalting equipment with the weary steam that electric turbine is discharged as low-temperature multi-effect, promptly substitute the condenser of power generation system with first single-effect evaporator of low-temperature multi-effect evaporation seawater (brackish water) desalting equipment, after being condensed into water, the weary steam that steam turbine is discharged recycles, generating and sea water desaltination cost are reduced significantly, and the energy utilization rate of unit obviously improves.
Description of drawings:
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment:
Below in conjunction with description of drawings the specific embodiment of the present invention.As shown in Figure 1: with existing generating set, the steam turbine that boiler is arranged and join with it, the weary discharge of steam of steam turbine is to condenser, agglomerative water joins through water circulating pump and boiler behind condenser, different is with prior art, condenser is first single-effect evaporator of low-temperature multi-effect evaporation desalination device, and low-temperature multi-effect evaporation desalination device is multiple-effect horizontal tube falling film evaporation device preferably.In order further to improve sea water desaltination efficient, the seawater ingress of imitating the horizontal tube falling film evaporation device at N is provided with the seawater preheating condenser.
Between 110 ℃ ~ 60 ℃ of the terminal exhaust temperature scopes of steam turbine, the inlet air temperature of low-temperature multi-effect evaporation desalination device is set between 70 ℃ ~ 50 ℃, determine the operation scheme of steam turbine and vacuum tightness and the effect number that multiple-effect horizontal tube falling film evaporation device is used in sea water desaltination according to this temperature range: exhaust temperature is high more, the effect number of desalting equipment vaporizer is many more, and the steam discharge thermal resource is fully utilized.
