Abstract
The utility model discloses a device for improving burning efficiency of a COREX vertical-mill hot blast furnace. The device comprises a barrel (4), an outer flame baffle plate (2) is arranged on the outer wall of the barrel (4), an inner isolation plate (1) is arranged on the inner wall of the barrel, eight guide plates (3) are uniformly distributed between the outer flame baffle plate (2) and the inner isolation plate (1) and are all connected with an adjusting ring (5). The section of each guide plate (3) is arc-shaped, projections (3a and 3a') are symmetrically arranged on two sides of the guide plates (3), and the guide plates are arranged between the inner isolation plate (1) and the outer flame baffle plate (2) through the projections on two sides. The arc angle of each guide plate (3) ranges from 60 degrees to 100 degrees. The original linear guide plates are modified into adjustable plates, and arc angles of the guide plates are adjusted by the adjusting ring, so that flame gathering is realized, and the burning efficiency of the hot blast furnace is improved evidently.
Description
Technical field
The utility model relates to a kind of device for improving COREX hot blast stove of vertical grinder efficiency of combustion.Belong to COREX hot blast stove of vertical grinder accessory technical field.
Background technology
The COREX hot blast stove of vertical grinder is as supplying heat source at present, and its combustion medium is blast furnace gas and coke-stove gas.Coke-stove gas sprays burning in the middle of internal partition in process of production, and blast furnace gas sprays in deflector, burns after lighting by coke-stove gas.Because the deflector of COREX hot blast stove of vertical grinder burner cylindrical shell is linear pattern, the flame effect that in use burning produces is diffused, causes calorific value to gather, and efficiency of combustion is lower.And part flame directly burns to fire resisting material of furnace body, and long-time high-temperature baking obviously reduces the service life of refractory material.In addition, needing that aborning material is carried out the transient heating baking processes, this just needs stable thermal source supply, and the thermal source that diffused flame produces is unfavorable for the conveying of heat continous-stable, has caused the problems such as the vibration of Vertical Mill production line is large, the bed of material is unstable, specific energy consumption is high to occur.
The utility model content
Technical problem to be solved in the utility model provides a kind of device for improving COREX hot blast stove of vertical grinder efficiency of combustion, can gather thermal source, improves efficiency of combustion.
The technical scheme that the utility model addresses the above problem is as follows:
A kind of device for improving COREX hot blast stove of vertical grinder efficiency of combustion comprises cylindrical shell, and the outer wall of described cylindrical shell is the flame envelope baffle plate, the inwall of cylindrical shell is internal partition, be evenly distributed with several deflectors between described flame envelope baffle plate and the internal partition, described deflector all is connected with adjustment ring, it is characterized in that:
The cross sectional shape of described deflector is circular arc, and the bilateral symmetry of deflector is provided with projection, and deflector is connected between internal partition and the flame envelope baffle plate by the projection of both sides.
Further, the arc chord angle of described deflector is 60～100 °.
As preferably, the quantity of described deflector is 8.
Compared with prior art, change former linear pattern deflector into adjusting plate, by adjustment ring the arc angle of deflector is adjusted, gather the effect of flame to reach effect, avoid flame shape transition diffusion, the efficiency of combustion of hot-blast stove is improved significantly.By repeatedly adjusting test, the blast furnace gas flame shape is the rotation compact by diffusion-type transition, and the baking of the anti-material of body of heater is obviously reduced, and anti-material temperature drops to 500 ℃ by improving front 750 ℃, and under the identical working environment, specific energy consumption descends about 8%.The efficiency of combustion of hot-blast stove obviously improves.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of deflector.
Among the figure: 1, internal partition; 2, flame envelope baffle plate; 3, deflector; 3a, 3a ', projection; 4, cylindrical shell; 5, adjustment ring;
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
As shown in Figure 1, a kind of device for improving COREX hot blast stove of vertical grinder efficiency of combustion, comprise cylindrical shell 4, the outer wall of described cylindrical shell is flame envelope baffle plate 2, the inwall of cylindrical shell is internal partition 1, be evenly distributed with several deflectors 3 between described flame envelope baffle plate 2 and the internal partition 1, described deflector 3 all is connected with adjustment ring 5, the cross sectional shape of described deflector 3 is circular arc, the bilateral symmetry of deflector is provided with projection 3a, 3a ', deflector is connected between internal partition 1 and the flame envelope baffle plate 2 by the projection of both sides, rotates adjustment ring 5, just can regulate the arc angle of deflector.The arc chord angle of described deflector 3 is 60 °～100 °.As required, the quantity of described deflector 3 is 8.
The course of work of the present utility model is, among described cylindrical shell 4 and the blast furnace gas burner figure not the inboard of expression supervisor be connected, coke-stove gas ejection burning in the middle of the internal partition, its flame is direct light type, blast furnace gas sprays in deflector, burns after lighting by coke-stove gas.Because the arc angle of deflector can be regulated by adjustment ring, can be the rotation compact by diffusion-type transition with the blast furnace gas flame shape therefore, gather flame and avoid flame shape transition diffusion to reach effect.The efficiency of combustion of hot-blast stove is improved significantly.
