Description
Technical field
The present invention relates to boiler washing pipe technical fields, and in particular to 660MW supercritical unit is rushed without boiler water circulating pump boiler
Guard system.
Background technique
After boiler is used for a long time, can be deposited on the inner wall of boiler a large amount of steam dirt, iron filings and with the sundries such as iron rust,
When the sundries in boiler runs up to a certain amount of, it may appear that a part of sundries falls off, and when the sundries to fall off is larger, just will appear
Sundries blocks steam conveying pipeline and pipe is caused to overheat explosion, or sundries occurs and impinge upon on turbine blade with high speed steam flow
Leaf destruction is caused, has caused a serious accident.The most susceptible to plugging steam conveying pipeline of sundries come out from boiler is just proximate to pot
One section of nearest steam conveying pipeline of furnace, as long as often clear to sundries is carried out close to one section of nearest steam conveying pipeline of boiler
It removes, the steam conveying pipeline of steam turbine will be made unimpeded.
When being now to eliminating impurities are carried out close to the closer one section of steam conveying pipeline of boiler, it is necessary to stop steam conveying
Pipeline is to steam turbine steam supply, to cause halt turbines.
Summary of the invention
When the present invention is to solve now to eliminating impurities are carried out close to the closer one section of steam conveying pipeline of boiler, need
Stopping steam conveying pipeline to just can be carried out after steam turbine steam supply, to cause the deficiency of halt turbines, providing one kind not
The steam supply of steam turbine can be achieved with carrying out to close to the closer one section of steam conveying pipeline of boiler with steam conveying pipeline is stopped
Eliminating impurities, highly-safe, the 660MW supercritical unit of good reliability is without boiler water circulating pump boiler tube system.
The above technical problem is solved through the following technical scheme:
660MW supercritical unit is without boiler water circulating pump boiler tube system, including boiler, steam lead, supervisor, out steam
Pipe, side pipe, scale removing tube and dirt removal device；The left nozzle of supervisor includes the upper left nozzle and lower-left nozzle arranged in forked,
The right nozzle of supervisor includes the upper right nozzle and bottom right nozzle in forked arrangement；The left end of side pipe is curved in arc-shaped downwardly toward the right side
The left bending segment pipe of side pipe is obtained after folding, the right end of side pipe obtains the right bending segment of side pipe after bending downwardly toward a left side in arc-shaped
Pipe；One end of steam lead is connected on the lower-left nozzle of supervisor, and the other end of steam lead is connected in boiler
On one steam (vapor) outlet；The left end of steam pipe is connected on the bottom right nozzle of supervisor out, and the bending segment pipe of side pipe is in succession
It connects on the upper left nozzle of supervisor, the right bending segment pipe of side pipe is connected on the upper right nozzle of supervisor；To allow after connection
Side pipe and supervisor formed a perimetrical lumen；Dirt removal device is movably arranged in perimetrical lumen, and dirt removal device energy
It is mobile in perimetrical lumen annular；If side pipe is made of left bending segment pipe, middle section pipe and right bending segment pipe；At right bending segment pipe
The middle section pipe of side pipe be equipped with side steam inlet, the both ends of an auxiliary tube are connected on the steam inlet of side and boiler
On another steam (vapor) outlet；And the steam flowed out from auxiliary tube can push dirt removal device to move counterclockwise in perimetrical lumen
