Abstract
The invention provides a technical scheme of a guiding device for a water cooled wall. In the technical scheme, the middle part of the guiding device is provided with a water cooled wall tube curved outwards and a water cooled wall refractory lining; a platform extending towards a hearth is arranged at the upper top end of the water cooled wall refractory lining and is positioned on the upper part, which is curved outwards, of the water cooled wall tube, the width H of the platform is between 10 and 50 centimeters, an included angle a between a platform surface and the axis of the water cooled wall tube is between 45 and 150 degrees; the water cooled wall refractory lining between the heath end of the platform and the bottom, which is curved outwards, of the water cooled wall tube is a guiding surface, and an included angle d between the guiding surface and a plane is between 20 and 80 degrees; and in the water cooled wall refractory lining enclosed by the platform surface and the guiding surface, a radiator is connected to the water cooled wall tube on the upper part, which is curved outwards, of the water cooled wall tube.
Description
Technical field
What the present invention relates to is a kind of structure of fluid bed boiler water-cooling wall, especially a kind of guider of water-cooling wall.
Background technology
In the prior art, technique known is that No. 90100764.1 patents open and that expired are authorized by Patent Office of State Intellectual Property Office, this patent disclosure the water-cooling wall in a kind of fluidized-bed reactor, its objective is the wearing and tearing that reduce water-cooling wall refractory lining top water screen tube, also is anti-wear structure preferably at present.But in actual motion, find, intersection at water-cooling wall refractory lining top and water screen tube, the wearing and tearing of water-cooling wall refractory lining and water screen tube are still quite serious, after operation a period of time, just can form the mechanical wear pit and have to change water screen tube, therefore want the abrasion condition of running check water screen tube, this causes great trouble and inconvenience for operation work, and this is the existing in prior technology weak point.
Summary of the invention
Purpose of the present invention is exactly at the existing in prior technology deficiency, and provide a kind of guider technical scheme of water-cooling wall, a platform is extended to burner hearth in this scheme employing top on the water-cooling wall refractory lining, burner hearth has just formed a reducing, make furnace charge by after on the lower furnace portion, the reducing guiding furnace charge that forms through the water-cooling wall refractory lining flows to lower furnace portion, and this has just prevented the friction of furnace charge to water-cooling wall refractory lining top edge water screen tube, has thoroughly prevented the wearing and tearing of water screen tube.
This programme is realized by following technical measures: comprise that there are bandy water screen tube and water-cooling wall refractory lining in the middle part, there is a platform to the burner hearth extension on the characteristics of this programme top on described water-cooling wall refractory lining, this platform is positioned at the bandy top of water screen tube, the width H=10-50 of platform centimetre, angle a=45-150 degree between flat surface and water screen tube axis, the burner hearth end of platform is a spigot surface to the water-cooling wall refractory lining between the bandy bottom of water screen tube, the angle d=20-80 degree between this spigot surface and the horizontal plane; In the water-cooling wall refractory lining of described flat surface and spigot surface encirclement, be connected with a radiator on the bandy upper water cold wall pipe of water screen tube.The concrete characteristics of this programme also have, and described radiator is the cooling water pipe or the metal bar of Arabic numerals 7 types.The top water pipe of described cooling water pipe and the angle b=90-30 degree between the water screen tube axis are preferably 45.The bottom water pipe of described cooling water pipe and the angle c=20-90 degree between the water screen tube axis are preferably 30 degree.The width H of described platform is preferably 30 centimetres.Angle a between described flat surface and water screen tube axis is preferably 90 degree.Angle d between described spigot surface and the horizontal plane is preferably 45 degree.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme.A platform is extended to burner hearth in employing top on the water-cooling wall refractory lining, make burner hearth just form a reducing that taper is arranged, after furnace charge comes on by lower furnace portion, the taper reducing guiding furnace charge that forms through the water-cooling wall refractory lining returns to lower furnace portion mobile, the whirlpool diameter that causes in reducing place, be less than the distance of reducing to water screen tube, therefore, can not occur causing the mechanical friction of furnace charge to water screen tube because of whirlpool, this has just prevented the friction of furnace charge to water-cooling wall refractory lining top edge water screen tube, has thoroughly prevented the wearing and tearing of water screen tube.Being added in has cooling water pipe cooling water-cooling wall refractory lining again in the outstanding water-cooling wall refractory lining of platform, make the temperature of water-cooling wall refractory lining can be not too high, and this has guaranteed the intensity of water-cooling wall refractory lining on the one hand, does not also influence the heat exchange effect of water screen tube simultaneously.This shows that the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the specific embodiment of the invention.
Among the figure, 1 is water screen tube, and 2 is cooling water pipe, and 3 is platform, and 4 is the water-cooling wall refractory lining, and 5 is spigot surface, and 6 is burner hearth.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the guider of the water-cooling wall of this programme, comprise that there are bandy water screen tube and water-cooling wall refractory lining in the middle part, there is a platform to the burner hearth extension on this programme top on described water-cooling wall refractory lining, this platform is positioned at the bandy top of water screen tube, the width H=10-50 of platform centimetre, this specific embodiment adopts H=30 centimetre.Angle a=45-150 degree between described flat surface and water screen tube axis, the angle between flat surface of this specific embodiment and water screen tube axis is the a=90 degree.The burner hearth end of platform is a spigot surface to the water-cooling wall refractory lining between the bandy bottom of water screen tube, spigot surface makes burner hearth form a taper reducing, angle d=20-80 degree between this spigot surface and the horizontal plane, the angle d=45 degree that this specific embodiment adopts.In the water-cooling wall refractory lining of described flat surface and spigot surface encirclement, be connected with a radiator on the bandy upper water cold wall pipe of water screen tube, this radiator is the cooling water pipe or the metal bar of Arabic numerals 7 types, and what this specific embodiment adopted is cooling water pipe.The top water pipe of described cooling water pipe and the angle b=90-30 degree between the water screen tube axis, what this specific embodiment adopted is the b=45 degree.The bottom water pipe of described cooling water pipe and the angle c=20-90 degree between the water screen tube axis, what this specific embodiment adopted is the c=30 degree.
The present invention is not limited in the above-mentioned specific embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
