Description
Technical field
This utility model belongs to technical field of metallurgical equipment, is related to a kind of simple structure, raising coal dust combustion easy to use
The blast furnace spray gun head of burning rate.
Background technology
Traditional coal powder lance for blast furnace carries out coal powder injection operation using straight spray gun, but finds in actual use, works as height
Stove injecting coal quantity reaches 170~180kg/t, and higher 28~33%, the Jing that reaches of phosphorus content analyzes some coal dust not in dedusting ash
Can completely burn, enter in dedusting ash in carbon residue shape, and the initial distribution shape of the imperfect combustion of coal dust and coal dust when going out spray gun
State has much relations, sees from air port peephole and looks into coal dust and go out in plume shape is concentrated after spray gun, and area of dispersion is less, edge portions and heat
More fully burning is more abundant for wind contact, and many little air burnings of middle body coal less completely, easily produce unburned coal powder,
To solve this problem, the initial distribution for changing coal dust is needed, reduce the coal dust that middle body is excessively concentrated, expand whole coal dust
The area of dispersion of stream, increases the probability mixed with air contact, and to reach the clean-burning purpose of coal dust is enable, therefore, grind
Send out a kind of improve coal combustion rate blast furnace spray gun head it is significant..
The content of the invention
The purpose of this utility model is to provide a kind of simple structure, the blast furnace spray of raising coal combustion rate easy to use
Pipette tips.
The purpose of this utility model is achieved in that including body the body is set to circular tube shaped, the body
Exit arranges scattering guide body.
This utility model tubular lance head nozzle arrange cone scattering guide body, make coal dust spray when,
Spray along conical surface scattering, coal dust is separated into into thin coal mist, it is more abundant with air contact in burning, complete to fill
Divided combustion；The spray tank of axis direction is set on the pipe of lance head, part coal dust is reached before circular cone scattering guide body just
Spray from spray tank, strengthen the scattering degree of coal dust, also mitigate injection pressure of the coal dust in exit；This utility model structure
Simply, it is easy to use, the burning of coal dust is completed to greatest extent, make the energy be fully utilized.
Description of the drawings
Fig. 1 is this utility model structural representation；
Fig. 2 is the left view structural representation of Fig. 1；
In figure：1- bodies, 2- spray tanks, 3- connecting plates, 4- scattering guide bodies.
Specific embodiment
This utility model is further described below in conjunction with the accompanying drawings, but this utility model must not be added by any way
To limit, any change or improvement based on this utility model training centre work belongs to protection domain of the present utility model.
As shown in Figure 1 and 2, this utility model includes body 1, and the body 1 is set to circular tube shaped, the outlet of the body 1
Place arranges scattering guide body 4.
The scattering guide body 4 is set to bullet, the microcephaly of the bullet towards it is relative with the direction of coal dust output,
Major part direction is identical with coal dust outbound course.
The stub end of the bullet is concordant with the port of export of body 1, and the bullet is connected to body 1 by connecting plate 3
Inwall on.
Spray tank 2, the principle that spray tank is arranged are set in the axial direction on the outlet section of the body 1, it is ensured that installing
Lance outlet equivalent aera after guiding bullet will not just occur stifled rifle more than former discharge area.
In the uneven setting 3 ~ 5 in three directions of circumference of body 1, tuyere small sleeve side can not slot the spray tank 2,
In order to avoid abrasion tuyere small sleeve.
More than 2 ~ 3 times of length for scattering guide body 4, the spray tank 2 is arranged on scattering guiding to the length of the spray tank 2
The working front edge of body 4.
The width of the spray tank 2 is the 1/10 ~ 1/5 of the diameter of body 1.
Gap sectional area between the scattering guide body 4 and the inwall of body 1 is set to the 2 ~ 3 of the tube wall sectional area of body 1
Times.
The connecting plate 3 is an edge of a knife shape, and cutting edge is towards, the connecting plate 3 outlet from body 1 relative with the coal dust direction of motion
End is coupled with cone major part, reduces the resistance that coal dust passes through to greatest extent to the greatest extent.
Utility model works principle and the course of work：
This utility model tubular lance head nozzle arrange cone scattering guide body 4, make coal dust spray when,
Spray along conical surface scattering, coal dust is separated into into thin coal mist, it is more abundant with air contact in burning, complete to fill
Divided combustion；The spray tank 2 of axis direction is set on the pipe of lance head, part coal dust is reached before circular cone scattering guide body 4
Just spray from spray tank, strengthen the scattering degree of coal dust, also mitigate injection pressure of the coal dust in exit；This utility model is tied
Structure is simple, easy to use, and the burning of coal dust is completed to greatest extent, makes the energy be fully utilized.
