Abstract
The utility model discloses a kind of female pipe blowdown apparatus of steam turbine smoke exhaust fan outlet, including: main fuel tank, smoke exhaust fan, outlet mother pipe, the dirty well of storage, sewage draining valve, U-shaped blow-off pipe, female pipe, the dirty well of described storage is arranged on the lower section of female pipe and is connected with female pipe；Described outlet mother's pipe is perpendicular to female pipe connection；Described smoke exhaust fan is connected with outlet mother's pipe and main fuel tank respectively；The bottom of the dirty well of described storage is connected with U-shaped blow-off pipe；Described U-shaped blow-off pipe is double-U-shaped, and its other end is connected with sewage draining valve.This utility model have following technical effect that the female pipe blowdown apparatus of steam turbine smoke exhaust fan outlet that this utility model provides can continuous blowdown, to guarantee to export female pipe unimpeded without blocking, the negative pressure that maintains fuel tank, the safe and stable operation of turbine oil system is effectively ensured, it is to avoid unit has an accident.
Description
Technical field
This utility model relates to turbine oil system technical field, particularly to a kind of female pipe blowdown apparatus of steam turbine smoke exhaust fan outlet.
Background technology
Smoke exhaust fan is the important composition equipment of turbine oil system, and its effect is the oil smoke in eliminating fuel tank, steam, maintains the slight negative pressure (20～25mm water column) of fuel tank, to ensure that oil return is unobstructed.Every unit arranges two smoke exhaust fans, and one properly functioning and another is standby.If the female pipe of smoke exhaust fan outlet is due to hydrops or long-pending oil blocking, the most whole lubricating oil system just cannot set up negative pressure, system oil return is the most smooth, more seriously steam turbine bearing gets rid of oil outward and makes unit have an accident, the technical problems to be solved in the utility model is to install blowdown apparatus additional at the female pipe of smoke exhaust fan outlet, continuous blowdown, to guarantee to export female pipe unimpeded without blocking, the negative pressure that maintains fuel tank, the safe and stable operation of turbine oil system is effectively ensured, reduces unit failure incidence rate.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of simple in construction, runs the female pipe blowdown apparatus of steam turbine smoke exhaust fan outlet smoothly.
For achieving the above object, this utility model adopts the following technical scheme that realization: a kind of steam turbine smoke exhaust fan exports female pipe blowdown apparatus, including: main fuel tank, smoke exhaust fan, outlet mother pipe, the dirty well of storage, sewage draining valve, U-shaped blow-off pipe, female pipe, the dirty well of described storage is arranged on the lower section of female pipe and is connected with female pipe；Described outlet mother's pipe is perpendicular to female pipe connection；Described smoke exhaust fan is connected with outlet mother's pipe and main fuel tank respectively；The bottom of the dirty well of described storage is connected with U-shaped blow-off pipe；Described U-shaped blow-off pipe is double-U-shaped, and its other end is connected with sewage draining valve.
Preferably, cutting, cancel elbow, install self-control threeway additional at female pipe φ 159 × 4.5 elbow bend of smoke exhaust fan outlet, middle part is welded with former pipeline with top, and the straight tube self-assembling formation sewage well of length 800mm is set up in bottom.
Preferably, installing sewage door additional and connect 32 pairs of " U " type pipes of φ, the outlet of double " U " type pipe is connected to sump oil emission point.
This utility model have following technical effect that the female pipe blowdown apparatus of steam turbine smoke exhaust fan outlet that this utility model provides can continuous blowdown, to guarantee to export female pipe unimpeded without blocking, the negative pressure that maintains fuel tank, the safe and stable operation of turbine oil system is effectively ensured, it is to avoid unit has an accident.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
In order to be better understood from the technical solution of the utility model, describe the embodiment that this utility model provides below in conjunction with the accompanying drawings in detail.
The female pipe blowdown apparatus of this one steam turbine smoke exhaust fan outlet, including: main fuel tank 106, smoke exhaust fan 104, the female pipe 105 of outlet, the dirty well 102 of storage, sewage draining valve 107, U-shaped blow-off pipe 103, female pipe 101, the dirty well 102 of described storage is arranged on the lower section of female pipe 101 and is connected with female pipe 101；Described outlet mother's pipe 105 is perpendicular to female pipe 101 and connects；Described smoke exhaust fan 104 pipe 105 female with outlet and main fuel tank 106 respectively are connected；The bottom of the dirty well 102 of described storage is connected with U-shaped blow-off pipe 103；Described U-shaped blow-off pipe 103 is double-U-shaped, and its other end is connected with sewage draining valve 107.
After installing, after unit startup optimization is normal, dynamically observe the female pipe blowdown apparatus of transformed smoke exhaust fan outlet and connecting line, pipe valve No leakage, smoke exhaust fan is working properly, main fuel tank depressimeter display negative pressure is at (20～25mm water column), and oil return is unobstructed, normal continuous blowdown, the female pipe of smoke exhaust fan outlet, without clogging, is transformed successfully.
The female pipe blowdown apparatus of a kind of steam turbine smoke exhaust fan outlet provided this utility model embodiment above is described in detail, for one of ordinary skill in the art, thought according to this utility model embodiment, the most all will change, in sum, this specification content should not be construed as restriction of the present utility model.
