Abstract
The invention discloses an anti-blocking transformation method of a material returner fluidization wind pipe. The anti-blocking transformation method is characterized in that the material returner fluidization wind pipe is aslant transformed to conveniently and timely discharge internal furnace slag; the fluidization wind pipe connected with a header is transformed from lower connection to upper connection to prevent the furnace slag in a fluidization wind distribution header from flowing into a fluidization wind master pipe to block the fluidization wind pipe; and through the transformations, normal work of a material returner is guaranteed.
Description
Technical field
The present invention be more particularly directed to the anti-blocking remodeling method of a kind of material returning device fluidisation airduct.
Background technology
Tai'an, Huaneng Group Zhong Tai electricity generating corporation, Ltd #1,2 unit boilers from ALSTOM company of the U.S., to be Shanghai Furnace Factory Co., Ltd introduce that CFB boiler advanced technology designs, the super-pressure manufactured, resuperheat, a single drum natural circulation boiler.Boiler adopts two level air-distributions, and First air enters burner hearth from burner hearth bottom air distribution plate, blast cap, and Secondary Air enters burner hearth from combustion chamber pyramidal portion, and burner hearth bottom is provided with steel plate type air compartment, is suspended on furnace wall cooling lower collecting box.
The shortcoming of existing scheme is: slag enters after fluidized wind distributes header can continue to flow to the female pipeline of the vertical current wind transmission be connected with header immediately below being in, and boiler material returning device fault Matter Transfer will be caused to be obstructed, be forced to blowing out after vertical female pipeline accumulated slag.The object of the invention is the shutdown of boiler solved because fluidized wind pipe-line system blocking material returning device causes.
Summary of the invention
The present invention mainly solves boiler material returning device fluidized wind mother pipe with distributing after header enters slag and blocks the boiler material returning device caused and cannot normally work.
The anti-blocking remodeling method of material returning device fluidisation airduct of the present invention, it is characterized in that: inner slag is convenient in material returning device fluidized wind header inclination transformation and discharges in time, the fluidized wind pipeline be connected with header is transform as upper connection by lower connection, avoiding the fluidized wind slag distributed in header to continue trickling choked flow wind transmission pipeline in the female pipeline of fluidized wind, ensureing that material returning device normally works by transforming above.
The invention has the beneficial effects as follows: change fluidized wind pipeline into upper connection to distributing header moral connected mode by lower connection, slag in distribution header can be avoided after changing connection into fall into blocking pipe in vertical female pipe and to cause the blowing out of material returning device fault, former horizontally disposed material returning device fluidized wind header is transform as and is in tilted layout, and in bottom, ash gate is installed, enter the slag distributed in header and discharged by bottom ash gate.

Detailed description of the invention
According to Fig. 1: the anti-blocking remodeling method of material returning device fluidisation airduct of the present invention, it is characterized in that: inner slag is convenient in material returning device fluidized wind header (1) inclination transformation and discharges in time, the fluidized wind pipeline (2) be connected with header (1) is transform as upper connection by lower connection, avoiding the fluidized wind slag distributed in header (1) to continue trickling choked flow wind transmission pipeline in the female pipeline of fluidized wind, ensureing that material returning device normally works by transforming above.
Claims (1)
1. the anti-blocking remodeling method of material returning device fluidisation airduct, is characterized in that: transformation of material returning device fluidized wind header (1) being tilted, transform by lower connection the fluidized wind pipeline (2) be connected with header as upper connection.
