Abstract
The utility model discloses a center water-cooling type blast furnace tuyere, relating to a blast furnace tuyere. The center water-cooling type blast furnace tuyere comprises a tuyere outer wall and a tuyere inner wall, wherein an air inlet is arranged at the upper end of the tuyere inner wall; and an air outlet is arranged at the lower end of the tuyere inner wall. The center water-cooling type blast furnace tuyere is characterized in that a water separation cavity is arranged between the tuyere outer wall and the tuyere inner wall to form an inner water cavity structure and an outer water cavity structure; an inner water cavity is communicated with a water inlet hole; and an outer water cavity is communicated with a water outlet hole. The center water-cooling type blast furnace tuyere has the beneficial effects that: the conventional water circulation mode is changed, the water-flowing speed is high, the cooling effect is good, the structure is simple, the manufacturing cost is low, the operation is easy, and the practicability is strong.
Description
Technical field
The utility model relates to a kind of blast-furnace tuyere, specifically is a kind of center water-cooled blast-furnace tuyere.
Background technology
Blast-furnace tuyere is the critical process spare of iron work in the Iron and Steel Production, and high-temperature hot-air and furnace bottom coke oxidizing fire by blast-furnace tuyere is blown into restore the iron that exists with oxide form.Blast-furnace tuyere is installed in the furnace wall between bosh and the furnace bottom usually; Front end has 500mm to go deep in the stove; Directly receive the hot erosion of liquid slag iron and the heavy wear of the heat material that drops, the environment for use of blast-furnace tuyere is exceedingly odious, not only will bear the above high temperature of about 1500 degree; Also will bear washing away with the wearing and tearing of furnace charge, slag of high temperature flowing molten iron and lose efficacy easily, the frequent change air port causes the blast furnace staying and the underproduction.
At present, according to different blast furnace operating modes and different request for utilization, economic requirements, scientific and technical personnel have designed the blast-furnace tuyere of multiple water-cooling structure.The blast-furnace tuyere structure of using both at home and abroad mainly contains: cavity water cooled tuyere, two-chamber swirl diffuser, throughflow tuyere, the air port that goes with each other all the time, centering type air port.Cavity type structure inlet front end is prone to form the cooling dead band; Cause air port cover front end local superheating, rotating, the tubular streaming of two-chamber, the formula that goes with each other all the time, the existence in various degree of centering type cooling structure, cooling water pressure is not enough; Flow is little; Flow velocity is low, is not enough to take away the air port and puts the accumulative heat, causes the blast-furnace tuyere life-span low.So there is certain problem in the existing type of cooling.
Summary of the invention
The utility model is in order to remedy the deficiency of prior art, provides that a kind of flow velocity is fast, the center water-cooled blast-furnace tuyere of good water cooling effect.
The utility model comprises air port outer wall and air port inwall; The upper end of air port inwall is provided with blast inlet; The lower end is provided with air outlet, and its special character is: be provided with the water proof chamber between described air port outer wall and the air port inwall, water cavity and outer water cavity structure in constituting; Interior water cavity and prosopyle are connected, and outer water cavity and posticum are connected.Water cavity in outside water coolant gets into through the prosopyle after the arrival tuyere bottom, can flow in the outer water cavity through the space between water proof chamber and the tuyere bottom; Outer water cavity communicates with posticum; The water coolant that gets into outer water cavity just can flow out through posticum, and is simple to operate, good cooling results.
The bottom in described water proof chamber is that non-closed contact is connected with the bottom, air port.The water of water cavity just can get in the outer water cavity easily in getting into like this.
The beneficial effect of the center water-cooled blast-furnace tuyere of the utility model: change water cycle mode in the past, flow velocity is fast, and good cooling results is simple in structure, low cost of manufacture, and easy handling is suitable for blast-furnace tuyere and uses.

Among the figure: 1, posticum, 2, blast inlet, 3, hot-air channel, 4, the prosopyle, 5, the air port base, 6, the air port outer wall, 7, the air port inwall, 8, outer water cavity, 9, the water proof chamber, 10, interior water cavity, 11, the bottom, air port, 12, air outlet.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Accompanying drawing is a kind of specific embodiment of the utility model; This embodiment comprises air port outer wall 6 and air port inwall 7, and the upper end of air port inwall 7 is provided with blast inlet 2, and the lower end is provided with air outlet 12; Be provided with water proof chamber 9 between described air port outer wall 6 and the air port inwall 7; Water cavity 10 and outer water cavity 8 structures in constituting, interior water cavity 10 is connected with prosopyle 4, and outer water cavity 8 is connected with posticum 1.The bottom in described water proof chamber 9 and bottom, air port 11 are connected for non-closed contact.
The utility model in use; Water is poured in the interior water cavity 10 through prosopyle 4; Arrive tuyere bottom 11 places, owing to have the space between tuyere bottom 11 and the water proof chamber 9, so water coolant will flow in the outer water cavity 8 through the slit; Outer water cavity 8 is connected with posticum 1, and water coolant will flow into the outside through posticum 1.Completion is for the water cooling effect of blast-furnace tuyere, and is simple to operate, easy to use.
