The utility model provides a kind of coke dry quenching furnace flue water-cooled bracket, comprise furnace shell and refractory brick, around described furnace shell inboard, be provided with the water cooled pipeline of a plurality of one-tenth " 7 " font, fixedly connected with furnace shell to form the water-cooled bracket in the upper and lower of this water cooled pipeline, this water cooled pipeline links to each other with rising pipe with the water inlet pipe in the furnace shell outside.
According to coke dry quenching furnace flue water-cooled bracket of the present utility model, also can be provided with first and strengthen gusset in the interior angle corner of " 7 " word of the water cooled pipeline of described " 7 " font, strengthen gusset in the furnace shell arranged outside second that is connected with the import and export of water cooled pipeline simultaneously, to play local booster action to the junction of water cooled pipeline and furnace shell.
According to coke dry quenching furnace flue water-cooled bracket of the present utility model, also can be provided with an annular heating resisting metal plate and be connected, in order to support the flue inwall with water cooled pipeline with a plurality of one-tenth " 7 " font on the top of the water cooled pipeline of described a plurality of one-tenth " 7 " font; In the bottom of the water cooled pipeline of a plurality of one-tenth " 7 " font, the inboard of furnace shell also can be provided with support ring, with fixing and support the flue outer wall.
Brick bracket compared to existing technology, dried breath coke oven flue water-cooled bracket of the present utility model has following advantage:
1,, ceases the interior hot gas flow of coke oven so it can bear red Jiao's thermal radiation and do, thereby avoided the brickwork construction bracket under the environment that colds and heat succeed each other, to produce longitudinal crack and disconnected brick phenomenon because dried breath coke oven flue water-cooled bracket of the present utility model is a water-cooling structure.
2, because the outside of the water cooled pipeline of a plurality of " 7 " font in the dried breath coke oven flue water-cooled bracket of the present utility model is coated with heat resistance fiber and refractory castable, avoid air-flow to the washing away of the water cooled pipeline of " 7 " font, so the utility model life-span reaches 4 years.
3, by utilization, can improve recovery ability to red burnt waste heat to the recirculated cooling water in the water-cooled bracket described in the utility model.
And, because the water cooled pipeline of a plurality of " 7 " font in the dried breath coke oven flue water-cooled bracket of the present utility model outside coats heat resistance fiber and refractory castable, so cooling water amount can be not too many yet.
