Description
Technical field
The present invention relates to steam turbine field, starts Analysis of Exhaust Steam Recovering System more particularly, to a kind of back pressure turbine.
Background technology
In the heating project provided with back pressure turbine, as shown in figure 1, the characteristics of due to back pressure turbine itself,
Unit is generally provided with startup exhaust line, towards sky steam discharge when being mismatched for parameter during unit starting, protects unit
And system.The startup exhaust line in operation can there are the following problems：
(1) in start-up course, when the exhaust steam pressure of back pressure turbine is less than the requirement of heat supply heating network pressure, unit is only
Idle discharge vapour can be caused substantial amounts of medium-loss and heat loss, caused " visual pollution " during this period.
(2) during steam discharge is started, huge noise can be produced, urban environment is impacted.Particularly factory site position
There are many residents and commercial land in distributed busbar protection project in down town, factory site side, and the control for noise will be non-
Chang Yange.
The content of the invention
It is an object of the invention to：The problem of existing for prior art, there is provided a kind of back pressure turbine starts steam discharge
Recovery system, solves the problems such as working medium waste, " visual pollution ", noise pollution existing for back pressure turbine start-up course.
The goal of the invention of the present invention is achieved through the following technical solutions：
A kind of back pressure turbine starts Analysis of Exhaust Steam Recovering System, it is characterised in that the system includes hybrid startup steam discharge
Heater, start steam discharge recovery boiler, start exhaust line, low temperature desalination water lines, high temperature desalination water lines and demineralized water
Case, the hybrid startup steam discharge heater are connected by starting exhaust line with back pressure turbine, the hybrid startup
Steam discharge heater is connected by high temperature desalination water lines with starting steam discharge recovery boiler, and the sweet-water tank passes through low temperature desalination
Water lines are connected with hybrid startup steam discharge heater.
Preferably, desalination water pump and shut-off are sequentially provided between the sweet-water tank and hybrid startup steam discharge heater
Valve.
Preferably, the startup exhaust line, which is provided with, starts air bleeding valve.
Preferably, the high temperature desalination water lines are provided with shut-off valve.
Preferably, the startup steam discharge recovery boiler is connected with Recovery of the hot water pipeline, the Recovery of the hot water pipeline and low temperature
