Abstract
The invention relates to an anti-outflow device of a coal gasifier; the anti-outflow device includes an n-shaped anti-outflow ash blocking plate, and is characterized by also including an inverted-L shaped bracket; one side of the ash blocking plate is fixed with a coal bunker through a first bolt; a vertical section of the inverted-L shaped bracket is fixed with the coal bunker by a second bolt, a cross section of the inverted-L shaped bracket is connected with a horizontal section of the n-shaped anti-outflow ash blocking plate through a guide rail which can slide horizontally; the anti-outflow device of the gasifier utilizes the guide rail and a heat expansion and cold contraction effect of metals, one end of the anti-outflow device is fixed, and the other end of the anti-outflow device freely stretches out and draws back, so as to avoid a fracture phenomenon of the anti-outflow device during temperature changing and prolong the service cycle.
Description
Technical field
The present invention relates to the outer anti-stream device of a kind of coal gasifier, be specially adapted to small nitrogenous fertilizer plant intermittent coal gas stove.
Background technology
In little nitrogen enterprise, outer anti-stream device uses relatively more extensive on intermittent type vapourizing furnace, and play very important effect to the stable of gasification layer in coal gasifier, particularly old-fashioned mill construction, the gas furnace that cannot transform, anti-outflow device more seems important.
In actual motion, because of the processing condition of intermittent coal gas stove, anti-outflow device contacts repeatedly with the gasifying medium such as the red charcoal of high temperature, steam, water for a long time, temperature low during height during medium makes anti-outflow device generation deformation, but two ends are fixedly connected with mode causes its easy fracture, coal gasifier after fracture, is caused to collapse the loss of charcoal, the stream technology accident such as charcoal and feed coal.
Summary of the invention
For above-mentioned situation, the object of this invention is to provide the outer anti-stream device of a kind of coal gasifier, make simple, safe and reliable to operation, life cycle is long.
The outer anti-stream device of coal gasifier of the present invention, realize in the following way: the outer anti-stream device of a kind of coal gasifier, comprise the outer anti-stream ash damper of " n " shape, it also comprises an inverted "L" shaped support, the side of ash damper is fixed by a bolt and coal bunker, the perpendicular section of inverted "L" shaped support is fixed by the second bolt and coal bunker, inverted "L" shaped support the horizontal section of the outer anti-stream ash damper of crosspiece and " n " shape can the guide rail of horizontal slip be connected by one.
The outer anti-stream device of coal gasifier of the present invention, utilize the effect of expanding with heat and contract with cold of guide rail and metal, outer anti-stream device one end is fixed, one end free-extension, thus avoids the phenomenon of rupture of outer anti-stream device when temperature variation, extends life cycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the outer anti-stream device of a kind of coal gasifier, comprise the outer anti-stream ash damper 1 of " n " shape, it also comprises an inverted "L" shaped support 3, the side of ash damper 1 is fixed by the first bolt 5 and coal bunker 2, the perpendicular section of inverted "L" shaped support 3 is fixed by the second bolt 6 and coal bunker 2, inverted "L" shaped support 3 the horizontal section of crosspiece and " n " shape anti-stream ash damper 1 outward can the guide rail 4 of horizontal slip be connected by one.
In concrete use procedure, when outer anti-stream device contacts repeatedly with the gasifying medium such as the red charcoal of high temperature, steam, water for a long time, outer anti-stream device, by guide rail 4 free-extension in the horizontal direction between inverted "L" shaped support 3 and the horizontal section of the outer anti-stream ash damper 1 of " n " shape, prevents the phenomenon of rupture of outer anti-stream device when temperature variation.
Claims (1)
1. the outer anti-stream device of coal gasifier, comprise the outer anti-stream ash damper of " n " shape, characterized by further comprising an inverted "L" shaped support, the side of ash damper is fixed by the first bolt and coal bunker, the perpendicular section of inverted "L" shaped support is fixed by the second bolt and coal bunker, and the horizontal section of the crosspiece of inverted "L" shaped support and the outer anti-stream ash damper of " n " shape can the guide rail of horizontal slip be connected by one.
