Abstract
The utility model relates to a multi-flow-passageway blast-furnace tuyere and belongs to the technical field of blast-furnace accessories. The multi-flow-passageway blast-furnace tuyere comprises a cross flow type structure and a cavity type structure. The multi-flow-passageway blast-furnace tuyere further comprises a multi-hole type structure, wherein the cross flow type structure is used in the front portion of the blast-furnace tuyere, the multi-hole type structure is used in the middle portion of the blast-furnace tuyere, the cavity type structure is used in the back portion of the blast-furnace tuyere, a cross flow part, a multi-hole part and a cavity part are respectively provided with an independent set of a water inlet and a water outlet, the tuyere of the cross flow part and the tuyere of the cavity part are respectively provided with a cooling room, the multi-hole part is provided with a flow returning room, the water inlet of the cross flow part and the water outlet of the cross flow part are connected with the cooling room, and the water inlet of the cavity part and the water outlet of the cavity part are connected with the cooling room. The multi-flow-passageway blast-furnace tuyere has the advantages of being high in cooling water flow speed, strong in cooling intensity, not prone to be burnt or be damaged, and favorable for wind flowing out.
Description
Technical field
The utility model belongs to high furnace accessory technical field, particularly a kind of multiple flow passages blast-furnace tuyere.
Background technology
Blast-furnace tuyere adopts cavity type and the tubular structure that combines at present, and wherein cavity type easily damages, and work-ing life is short; Although it is not tubular fragile, long service life, but as long as inlet front end burns out and leaks, blast furnace just must be changed the air port by damping down, changes the air port process complicated, labor intensive and time, impact is produced, and causes production efficiency to reduce, and, the structure of gas backstreaming is not set, is unfavorable for the gas discharge.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of multiple flow passages blast-furnace tuyere.
The technical solution of the utility model is achieved in that and comprises tubular and the cavity type structure, this blast-furnace tuyere also comprises open grain structure, the blast-furnace tuyere fore portion adopts tubular structure, the blast-furnace tuyere middle portion adopts open grain structure, the cavity type structure is adopted in the blast-furnace tuyere rear section, through-flow part, porous part and cavity partly are equipped with 1 and overlap independently water-in and water outlet, the air port of through-flow part and cavity part is equipped with cooling room, porous part is provided with return passage, and the through-flow part all is connected with cooling room with water outlet with the water-in in cavity part air port.
Described vesicular structure is to be provided with at least 2 holes on the return passage inwall.
Wherein tubular structure is that through-flow part water-in connects through-flow part cooling room, and through-flow part cooling room is that multi-layer helical is arranged, and through-flow part cooling room connects through-flow part water outlet.
Wherein the cavity type structure is that cavity part water-in connects cavity part cooling room, and cavity part cooling room is individual layer, and cavity part cooling room connects cavity part water outlet.
Advantage of the present utility model: this blast-furnace tuyere fore portion adopts tubular structure, the high cooling intensity of water coolant flow velocity is large, be difficult for scaling loss, in case fore portion scaling loss, namely can close the intake-outlet of air port fore portion, middle portion adopts vesicular structure, be convenient to distinguished and admirablely go out, rear section, air port cavity partly is provided with independently intake-outlet, blast furnace can continue as usual to produce, can be because of Tuyere Damage not interim damping down, row is changed again when the blast furnace scheduled overhaul, thereby has improved economic benefit that blast furnace produces and mitigation technique personnel and workman's work load greatly.
