Description
Technical field
The utility model belongs to exhaust steam in steam turbine condensation technology field, and in particular to based on the small machine condenser being arranged in juxtaposition
With main frame condenser combined type condensing system.
Background technology
As energy-conservation and water saving pressure are increasing, the feed pump type of drive in modern major part thermal power plant is by electronic
Machine drives and transform Steam Turbine Driven as, to reduce station service power consumption rate, reaches energy-saving purpose.Current motor-driven is changed to vapour
When turbine drives, feed pump turbine steam discharge is directly arranged and carries condenser or main frame condenser to it.Small steam turbine exhaust steam is arranged
During to carrying condenser, condenser load with small turbine power condition changing, when small machine underrun, prevent by condenser winter
Jelly problem is notable, it is impossible to protect small machine condenser well, and easily cause condenser exert oneself it is disproportionate with energy consumption；Small steamer
Machine steam discharge is arranged during to main frame condenser, and main frame condenser can be made to exert oneself not enough, improves main frame exhaust pressure, causes steam turbine to do work
Ability reduction.Thus developmental research one kind is in order to improve turbine efficiency, while meet the system that small turbine operates needs, tool
There is important meaning.
Utility model content
The purpose of this utility model is directed to the in line entrance of current small steam turbine exhaust steam and carries condenser, can only condense small vapour
Turbine discharge, but in the winter time underrun when, easily cause condenser bursting by freezing, the problem of risk can be brought to main frame operation,
And provide a kind of based on the small machine condenser being arranged in juxtaposition and main frame condenser combined type condensing system.
To solve the above problems, the technical solution adopted in the utility model is：It is a kind of based on the small machine condensing being arranged in juxtaposition
Device and main frame condenser combined type condensing system, it includes：Small turbine, vacuum butterfly valve, small machine condenser, main frame, main frame coagulate
Vapour device and main frame steam exhaust device；The outlet of the small turbine passes through the import of blow-off line and small machine condenser with main frame respectively
Import with main frame condenser is connected；The vacuum butterfly valve is provided at the blow-off line between small turbine and small machine condenser
On；The outlet of the small machine condenser is connected by gradient hydrophobic pipeline with the import of main frame steam exhaust device, the main frame
The outlet of condenser is connected by drain pipe with the import of main frame steam exhaust device.
Further preferred embodiment, described small machine condenser is wet type condenser, connects the hydrophobic pipeline of small machine condenser
Gradient is 4-6 degree.
Compared with prior art, the utility model has advantages below：
Firstth, the small machine condenser of the utility model and main frame condenser are arranged in parallel, due in small steam turbine exhaust steam pipeline
On be mounted with vacuum butterfly valve, when vacuum butterfly valve is opened, can realize that small steam turbine exhaust steam and main frame steam discharge unrestricted choice back pressure are low
Condenser, main frame steam discharge and small machine steam discharge can not only be condensed, effectively reduce main frame condenser load, improve unit generation energy
Power, increases generating end power output.Meanwhile, it is capable to main frame exhaust pressure is reduced, so that the gross coal consumption rate of main frame substantially drops
It is low.When vacuum butterfly valve is closed, small machine condenser only receives the steam discharge from main frame, can substantially reduce main frame exhaust pressure, carries
Generatine set heat efficiency high, increases unit output, while preventing main frame steam discharge from entering small turbine, protection small turbine is without prejudice.
Secondth, at a temperature of winter environment, small machine condenser can just condense steam discharge in the case where recirculated water is not needed,
The power consumption of water circulating pump is effectively reduced, with good energy-conserving action.
Therefore, the utility model has simple system, investment operating cost low, using the small machine condenser that is arranged in parallel and
The complementation of main frame condenser, can realize effective cooling of small turbine and main frame steam discharge, with good economy and
Environmental benefit.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, the present embodiment is a kind of solidifying based on the small machine condenser being arranged in juxtaposition and main frame condenser combined type
Vapour system, it includes：Small turbine 1, vacuum butterfly valve 2, small machine condenser 3, main frame 4, main frame condenser 5 and main frame steam exhaust device
6；The outlet of the small turbine 1 passes through import of the blow-off line with small machine condenser 3 and main frame condenser 5 respectively with main frame 4
Import connection；The vacuum butterfly valve 2 is provided on the blow-off line between small turbine 1 and small machine condenser 3；It is described small
By gradient for the hydrophobic pipeline of 4-6 degree is connected with the import of main frame steam exhaust device 6, the main frame coagulates for the outlet of machine condenser 3
The outlet of vapour device 5 is connected by drain pipe with the import of main frame steam exhaust device 6.
The steam discharge of small turbine 1 and the steam discharge of main frame 4 described in the present embodiment can lead to small machine condenser 3 and main frame is solidifying
Vapour device 5, effectively cools down main frame 4 and the steam discharge of small turbine 1, and all connecting main frame 1 after steam discharge condensation coagulates steam exhaust device 6, realizes
The carbonated drink balance of power plant.The closing of vacuum butterfly valve 2 can control small turbine 1, and steam discharge and main frame steam discharge do not fall in stopping process
Stream, protects small turbine 1.Whole system can realize effective cooling of the steam discharge of small turbine 1 and the steam discharge of main frame 4.
