Abstract
The invention relates to a through-flow cavity type blast-furnace tuyere with double flow passages, which belongs to the technical field of blast-furnace fittings. The blast-furnace tuyere has a structural form of integrating through-flow type and cavity type, the front part of the blast-furnace tuyere has a through-flow type structure, the rear part of the blast-furnace tuyere has a cavity type structure, both the through-flow part and the cavity part are provided with a set of independent water inlet and water outlet, both the tuyeres at the through-flow part and the cavity part are provided with a cooling chamber, and the water inlets and the water outlets of the tuyeres on the through-flow part and the cavity part are communicated with the cooling chambers. The through-flow cavity type blast-furnace tuyere with the double flow passages has the advantages that: because the front part of the blast-furnace tuyere has the through-flow type structure, the flow speed of the cooling water is high and the cooling strength is large, and the front part is not easy to burn; once the front part is burnt, the water inlet and the water outlet on the front part of the tuyere can be closed; and because the cavity part on the rear part of the tuyere is provided with the independent water inlet and outlet, the blast furnace can continuously perform production and avoid blowing down for replacement due to the damage of the tuyere.
Description
Technical field
The invention belongs to high furnace accessory technical field, particularly a kind of through-flow cavity type blast-furnace tuyere with double flow passages.
Background technology
Blast-furnace tuyere adopts cavity type or tubular more at present, and wherein cavity type damages easily, and work-ing life is short; Though tubular not fragile, long service life is as long as inlet front end burns out and leaks, blast furnace just must be changed the air port by damping down, change air port process complexity, labor intensive and time, influence is produced, cause production efficiency to reduce, utility model patent 01241354.8 has been introduced the medium and small cover of a kind of double flow duct multiple-chamber type blast furnace wind cinder notch, and its shortcoming is that the air port fore portion burns out easily, and in case burn out the maintenance process complexity, influence is produced, and productivity reduces.
Summary of the invention
Deficiency at the prior art existence, the invention provides a kind of through-flow cavity type blast-furnace tuyere with double flow passages, by cavity type and tubular blast-furnace tuyere are carried out combination, make the blast-furnace tuyere long service life to reach, in case even scaling loss can be closed its Inlet and outlet water, another part still works on, make blast furnace continue to produce the purpose of enhancing productivity.
Technical scheme of the present invention is achieved in that this blast-furnace tuyere adopts tubular and cavity type to become the structure formation of one, the blast-furnace tuyere fore portion adopts tubular structure, the cavity type structure is adopted in the blast-furnace tuyere rear section, the through-flow part partly is equipped with 1 with cavity and overlaps independently water-in and water outlet, through-flow part and cavity part air port are equipped with cooling room, and the through-flow part all links to each other with cooling room with water outlet with the water-in in cavity part air port.
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 an individual layer, and cavity part cooling room connects cavity part water outlet.
Working process of the present invention: tubular structure and cavity type structure are independently unit, and the through-flow part water-in that water flows in the tubular structure of blast-furnace tuyere front end flows into through-flow part water outlet through the cooling of multilayer through-flow part cooling room; The cavity part water-in that water flows in the blast-furnace tuyere cavity type structure flows into cavity part water outlet through individual layer cavity part cooling room.
Advantage of the present invention: this blast-furnace tuyere fore portion adopts tubular structure, the high cooling intensity of water coolant flow velocity is big, be difficult for scaling loss, in case the fore portion scaling loss promptly can be closed the intake-outlet of air port fore portion, rear section, air port cavity partly is provided with independently intake-outlet, blast furnace can continue to produce as usual, can be because the air port damages interim damping down, when treating the blast furnace scheduled overhaul again row change, thereby improved economic benefit that blast furnace produces and mitigation technique personnel and workman's work load greatly.

Embodiment
The detailed structure of a kind of through-flow cavity type blast-furnace tuyere with double flow passages of the present invention is illustrated with accompanying drawing in conjunction with the embodiments.
This blast-furnace tuyere adopts tubular and cavity type to become the structure formation of one such as Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the blast-furnace tuyere fore portion adopts tubular structure, the cavity type structure is adopted in the blast-furnace tuyere rear section, the through-flow part partly is equipped with 1 with cavity and overlaps independently water-in and water outlet, the air port of through-flow part and cavity part is equipped with cooling room, and the through-flow part all links to each other with cooling room with water outlet with the water-in in cavity part air port.
Wherein tubular structure is that through-flow part water-in 3 connects through-flow part cooling room 6, and through-flow part cooling room 6 is that 4 helical layers are arranged, and through-flow part cooling room 6 connects through-flow part water outlet 4.
Wherein the cavity type structure is that cavity part water-in 1 connects cavity part cooling room 5, and cavity part cooling room 5 is an individual layer, and cavity part cooling room 5 connects cavity part water outlet 2.
