Be divided into two parts again after cylinder, a part of low-pressure steam, which enters oxygen-eliminating device and heated as the deoxygenation of boiler feedwater, to be used, another part after
Continuous acting, the steam for finishing work(is discharged into condenser and is condensed into water, again through feedwater after squeezing into oxygen-eliminating device heating deoxygenation through condensate pump
Pump squeezes into boiler and continues to heat generation steam.
The problem of current steam power plant heat energy utilization is present：
1）, steam power plant boiler circuit in, inevitably in the presence of the condensate of some loss of steam and water, especially heat user
When back amount is few, it is necessary to the water through desalting processing is supplemented into system in time.Fresh coolant-temperature gage is at 10 DEG C or so, at desalination
Temperature does not change substantially during reason, and boiler feedwater requires heat to 104 DEG C of ability deoxygenations, is that this needs a large amount of steam in heating
Vapour, increases primary energy consumption.
2）, when finishing in steam turbine the steam of work(and being discharged into condenser and be condensed into water, work as heat carrier with recirculated water, by cold
But steam condensation is dispersed into air by tower into heat during water, is not utilized, and the thermal efficiency is low.
The content of the invention
The utility model provides a kind of device that power plant is taken out to solidifying machine waste heat of condensation recycling realization energy-conservation, to solve at present
The increase primary energy consumption of presence, the steam for finishing in steam turbine work(are not utilized, the problem of thermal efficiency is low.
The utility model is adopted the technical scheme that：Water stop is connected with heat exchanger one, water stop also by valve one with
Desultwater Station is connected, and heat exchanger washs heat exchanger once valve two and starch workshop and is connected, Desultwater Station through feed pump respectively with
Heat exchanger two and valve three are connected, and heat exchanger two is connected with oxygen-eliminating device, and valve three is connected with oxygen-eliminating device, and oxygen-eliminating device connects with boiler
Connect, boiler is connected with steam turbine, steam turbine is connected with generator, user's sub-cylinder, oxygen-eliminating device respectively, the steam turbine is by taking out solidifying
The on-condensible gas pipeline of generation is connected with valve four, condenser, heat exchanger one, heat exchanger two respectively, valve four and heating heat-exchange
Device is connected, and condenser is connected with cooling tower.
The utility model has the advantages that structure is novel, newly-increased heat exchanger one, heat exchanger two and condenser is individually sealed
Operation is closed, is independent of each other, does not influence original system to run；Newly-increased heat exchanger one, heat exchanger two and condenser adds heat-transfer surface
Product, improves heat transfer effect, reduces the heat that the steam discharge of steam turbine discharges when being condensed into water, desalination coolant-temperature gage is by original
10 DEG C bring up to 40 DEG C reduce deoxygenation heating steam consumption, improve the heat utilization rate of whole therrmodynamic system；Starch washing
Water and heating do not need live steam to heat with water extraction temperature, save primary energy.
