Abstract
The utility model discloses a smoke pipeline of high -temperature furnace, the pipeline body that form is welded including the steel sheet, resistant firebrick and fixed through the bitch has been built by laying bricks or stones to pipeline body inner wall, the bitch is T type structure, is located between two upper and lower resistant firebrick, resistant firebrick opens on upper and lower terminal surface has the jack, upper and lower terminal surface on the resistant firebrick has the follow the logical groove that the jack extends to the inboard, the ejector pin of bitch is located lead to in the groove, the inner end of bitch is connected on the pipeline body, transplants on the outer end to insert the jack of terminal surface under the resistant firebrick in upper strata, and the underthrust stem cutting of outer end is gone into in the jack of lower floor's up end of nai firebrick. The utility model discloses a bitch buries and covers in resistant firebrick, and expend with heat and contract with cold warp for a short time for the difficult not hard up life who has drop, has improved smoke pipeline of high -temperature furnace of resistant firebrick.
Description
Technical field
The utility model belongs to boiler smoke duct technical field, is specifically related to one and is applied in boiler using brown coalIn stove smoke pipeline.
Background technology
In the blower mill unit pulverized-coal system in boiler using brown coal power plant, smoke from boiler using brown coalMouth is to the high-temperature furnace smoke pipeline of blower mill entrance, and its pumped (conveying) medium temperature is up to 1100 DEG C, at presentThe design of high-temperature furnace smoke pipeline, manufacture, have a kind of in insulation form, high-temperature furnace smoke pipeline adoptsOrdinary carbon steel sheet material is welded, and inner time with laying fireproof bricks, and fixes with bitch. At boilerIn the starting and stopping process of coal pulverizer, high-temperature flue gas temperature sharply changes between 20-1100 DEG C. ByAdopt iron and steel to make in bitch, the termination of bitch is exposed to refractory brick and directly contacts with high-temperature flue gas outward,Bitch can expand with heat and contract with cold and cause the loosening of refractory brick, produces obscission, stove smoke pipeline life-spanMore disconnected.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of refractory brick and is difficult for easily loosening high temperatureStove smoke pipeline, the deficiency existing to overcome prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of high-temperature furnace smoke pipeline, comprises the pipeline body that Plate Welding forms, in described pipeline bodyWall has been built refractory brick by laying bricks or stones and has been fixed by bitch, it is characterized in that: described bitch is T-shaped structure, positionBetween upper and lower two refractory brick, described refractory brick has jack on upper and lower end face, described fire-resistantUpper and lower end mask on brick has the groove extending from described jack to inboard, the mandril position of described bitchIn described groove, the inner end of described bitch is connected on pipeline body, transplants and insert on outer endIn the jack of layer refractory brick lower surface, under outer end, transplant and insert in the jack of lower floor's refractory brick upper surface.
In the utility model detailed description of the invention, described bitch is welded on described pipeline body. InstituteState the end face center that jack is positioned at refractory brick.
Adopt technique scheme, whole bitch all can be buried and cover by refractory brick, and bitch can be not directContact with high-temperature furnace smoke pipeline, bitch expand with heat and contract with cold distortion little, make refractory brick be difficult for loose or dislocation,Improve the service life of high-temperature furnace smoke pipeline.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Fig. 1 is pipe wall position structural representation of the present utility model;
Fig. 2 is the end view of refractory brick.
Detailed description of the invention
As shown in Figure 1, high-temperature furnace smoke pipeline of the present utility model, comprises the pipeline that Plate Welding formsBody 100, pipeline body 100 inwalls have been built refractory brick 200 by laying bricks or stones and have been passed through bitch 300.
Wherein, bitch 300 is T-shaped structure, comprises nail bar 301 and is positioned at the upper of nail bar 301 outer endsTransplant 302 and under transplant 303, bitch 300 is between upper and lower two refractory brick 200.
Shown in Fig. 2, refractory brick 200 has jack 201 in the center of upper and lower end face,Upper and lower end face on refractory brick also has the groove 202 extending from jack 201 to inboard.
Again as shown in Figure 1, the nail bar 301 of bitch 300 is arranged in groove 202, the weldering of bitch 300Be connected on pipeline body 100, in the jack of the 302 refractory brick lower surfaces, insertion upper strata of transplanting on outer end,Under outer end, transplant in the jack of 303 insertion lower floor refractory brick upper surfaces.
Adopt technique scheme, whole bitch all can be buried and cover by refractory brick, and bitch can be not directContact with high-temperature furnace smoke pipeline, bitch expand with heat and contract with cold distortion little, make refractory brick be difficult for loose or dislocation,Improve the service life of high-temperature furnace smoke pipeline.
