Abstract
The invention discloses an alignment device for an ash lock upper valve guide cylinder of a Lurgi gasifier. The alignment device comprises a circular tube, an upper ring, a lower ring and a disk, wherein the disk is fixed on a middle section of the circular tube; the upper ring and the lower ring are respectively fixed at two ends of the circular tube; and the center lines of the disk, the upper ring and the lower ring and the circular tube are coincident. With the adoption of the alignment device for the ash lock upper valve guide cylinder of the Lurgi gasifier, the problem that the ash lock upper valve guide cylinder to neutral is not easy to control is solved; a factor to influence the damage of the ash lock upper valve guide cylinder of the Lurgi gasifier is eliminated; the operation period of the Lurgi gasifier is prolonged; and the economic loss is reduced.
Description
Technical field
The present invention relates to the repair and maintenance that a kind of lurgi gasifier ash locks valve and use instrument, be specifically related to the alignment device that a kind of lurgi gasifier ash is locked the valve guide cylinder.
Background technology
The ash lock is the supporting band pressure ash equipment of German lurgi gasifier, is responsible for the lime-ash that produces in the lurgi gasifier gas-making process being discharged in order its working environment very severe of living in.It is one of critical component of ash lock that ash is locked valve, and when ash lock needed ash discharge, ash is locked valve needed that assurance is tight does not down in off position leak.The operating temperature that ash is locked valve is about 300 ℃; Sealing surface contacts with lime-ash, and the sealing between valve head and the valve seat will bear the high pressure of 3.0MPa, and it is very frequent to add switch; Each circulation all will be moved more than ten time; Clash into sealing surface repeatedly, it is fast unusually to cause ash to lock the damage of valve, changes frequent.
Lock in the maintenance replacing process of valve at the lurgi gasifier ash, need blowing out, pressure release, cooling after, pull down the ash lock and be shifted, finish changing ash and lock the driving that resets again behind the valve, the lurgi gasifier at least 18 hours of must stopping transport like this causes the cycle of operation of lurgi gasifier short especially.
And lock in the replacing process of valve at ash since ash lock the valve guide cylinder to the bad control of neutrality, ash is locked to be easy to generate between valve head and the upper valve base of valve and is pounded inclined to one side phenomenon, it is inhomogeneous to cause contact-making surface to be puted forth effort, and can increase the weight of the damage that ash is locked valve again.
Summary of the invention
The purpose of this invention is to provide a kind of lurgi gasifier ash and lock valve guide cylinder alignment device, lock the problem of valve guide cylinder the bad control of neutrality to solve ash.
Lurgi gasifier ash of the present invention is locked valve guide cylinder alignment device and is made up of pipe, last annulus, following annulus and disk; Said disk is fixed on the stage casing of pipe; Be fixed with annulus and following annulus at the two ends of pipe respectively, and said disk, go up the central lines of annulus, time annulus, pipe.
Wherein, the described internal diameter of going up annulus and following annulus specifically is the internal diameter less than pipe, greater than the diameter of last valve valve rod between round tube inside diameter and last valve stem diameter.
And then the present invention also is provided with a seam that cooperates with ash lock on said disk, and the center line of said seam equally and the central lines of pipe.
On said disk, also be provided with air-vent, said air-vent evenly distributes along the circumferencial direction of disk.
Lock in the valve maintenance replacing process at the lurgi gasifier ash; Ash is locked valve seat and is returned before the dress; Earlier lurgi gasifier ash of the present invention is locked valve guide cylinder alignment device and be placed on ash and lock, ash is locked the valve valve rod pass, just can lock the flange of the upper and lower guide ring of valve guide cylinder and adjust the gap between guide cylinder and the last valve valve rod through adjusting ash from its centre bore; Guaranteed ash lock the valve guide cylinder to neutrality; Having eliminated one influences the lurgi gasifier ash and locks the valve deadline factor, has prolonged the cycle of operation of lurgi gasifier, has reduced economic loss.
Description of drawings
Fig. 1 is the structural representation that lurgi gasifier ash of the present invention is locked valve guide cylinder alignment device.
Fig. 2 locks the user mode figure that uses alignment device of the present invention at the lurgi gasifier ash.
The specific embodiment
According to accompanying drawing the specific embodiment of the present invention is described below.
The lurgi gasifier ash is locked structure such as Fig. 1 of valve guide cylinder alignment device; By pipe 3; Be separately fixed at the last annulus 1 at pipe 3 two ends, annulus 2, and disk 4 compositions that are fixed on pipe 3 stage casings down, on disk 4, be provided with a seam 6 that cooperates with ash lock 5; And the circumferencial direction along disk 4 is evenly distributed with air-vent 7; Above-mentioned disk 4, go up annulus 1, the central lines of annulus 2, pipe 3, seam 6 down, the internal diameter of last annulus 1 and following annulus 2 is slightly less than the internal diameter of pipe 3, but greater than the diameter 0.5mm of last valve valve rod 8.
Lock in the valve maintenance replacing process at the lurgi gasifier ash; As shown in Figure 2; Lock before valve seat returns dress at ash, earlier the lurgi gasifier ash is locked valve guide cylinder centering instrument and be placed on above the ash lock 5, then the last valve valve rod 8 of ash lock 5 centre bore from the centering instrument is passed through seam 6 cards; Just can lock on the guide ring of valve guide cylinder 9 lower flange and adjust the gap between guide cylinder 9 and the last valve valve rod 8, make its centre-to-centre spacing be no more than 1mm through adjusting ash.
Claims (4)
1. a lurgi gasifier ash is locked valve guide cylinder alignment device; Form by pipe, last annulus, following annulus and disk; It is characterized in that said disk is fixed on the stage casing of pipe; Be fixed with annulus and following annulus respectively at the two ends of pipe, the central lines of said disk, last annulus, following annulus, pipe.
2. lurgi gasifier ash according to claim 1 is locked valve guide cylinder alignment device, it is characterized in that the said internal diameter of going up the internal diameter of annulus and following annulus less than pipe, greater than the diameter of last valve valve rod.
