BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blast furnace apparatus, and more particularly, to a blast furnace apparatus, in which a reaction gas is provided to be shifted upward from below and a charge is shifted upward from gravity by gravity.

The blast furnace operation is the work of charging and melting iron ore such as sintered oresite, etc. with the coke into the blast furnace, thereby heating and reducing the iron ore to produce molten iron as raw material for steelmaking.

In the blast furnace operation, the contents such as iron ore and coke are charged into the blast furnace through the charging device disposed on the upper part of the blast furnace. At this time, the charged raw materials are uniformly distributed without being biased to any one side of the blast furnace, It is needless to say that the reduction reaction must be performed normally to perform the operation with a good blast furnace.

By providing such a simulated reaction furnace 10, it is possible to provide a blast furnace environment similar to the actual blast furnace N than the conventional blast furnace L. That is, as can be seen from the graph of FIG. 8, the actual blast furnace N has a low temperature at the upper part, a temperature distribution in which the isothermal zone due to reduction reaction and heat loss occurs at the middle part, see.

On the other hand, in the conventional blast furnace apparatus (L), the temperature is slightly increased at the upper part, the isothermal zone is weak at the middle part, and the temperature is rapidly increased at the lower part. The reliability of the system can not be guaranteed.

However, in the blast furnace apparatus M of the present invention, the temperature rises from the upper part, the isothermal zone in the middle part becomes more apparent than the conventional blast furnace unit, and the temperature in the lower part rises weakly, L, the reliability of the blast furnace analysis can be improved by simulating the temperature distribution of the actual blast furnace N in a similar manner.

Providing the first upper hopper 33 and the second upper hopper 33 as described above can prevent the release of the charge c or the reaction gas g due to the pressure difference with the simulated reaction furnace 10 .

Specifically, when transferring the charge c from the lower hopper 31 to the second upper hopper 33 via the elevating portion 32, the second upper hopper 33 is connected to the lower hopper 33 (C) from the second upper hopper (33) to the first upper hopper (33) while maintaining the same pressure as the first upper hopper (31) The pressure of the first upper hopper 33 is kept equal to the pressure of the second upper hopper 33 and the amount of the charge c from the second upper hopper 33 to the first upper hopper 33, .

This is because, when the charge (c) such as iron ore, coke or the like is reduced by the reduction reaction, the volume increases, and thus the cross-sectional area of the hollow interior of the simulated reaction furnace

As a result, the sample (s) containing at least one of the charge (c) and the reaction gas (g) whose volume gradually increases can be smoothly lowered downward.

The simulated reaction furnace 10 may be formed such that the hollow inside the simulated reaction furnace 10 is inclined in the longitudinal direction y in order to increase the sectional area of the inner hollow from the upper end 11 to the lower end 12, It can be formed so as to decrease the area of the cross sectional direction (x) toward the lower side.

In order to form the cross-sectional area of the inner hollow larger from the upper end 11 to the lower end 12, the simulation reactor 10 has a shield tube 13b provided by the first temperature measuring unit 13 The shape may be formed to be smaller in the downward direction, and a detailed description thereof will be described later with reference to FIG.

The simulation reactor 10 may be divided into an upper end portion 11 and a lower end portion 12 and the furnace c and the reaction gas g may be heated by the lower end portion 12.

Thus, by charging the charge c and the reaction gas g, it is possible to perform the reduction reaction between the charge c and the reaction gas g as in the actual blast furnace. That is, the reaction gas g rises upward from the lower side and comes into contact with the charge c, and the heater H is provided at the lower end portion 12 of the simulation reactor 10, (C), which moves downward due to its own weight, can be sequentially heated to cause a reduction reaction with the reaction gas (g).

A heat insulating material may be formed at a portion adjacent to the inner hollow where the charge (c), the reaction gas (g) to the sample (s) are located for heat insulation of the upper end portion 11 or an insulating hollow may be formed. It may be provided to supply the same amount of heat as the amount of heat to be dissipated similarly to the heater H for maintaining the temperature.

In addition, the simulation reactor 10 of the blast furnace apparatus according to an embodiment of the present invention includes a second temperature measuring unit 14 provided at the outer side of the simulation reactor 10 to measure the temperature, The temperature control unit 15 may further include a temperature controller 15 connected to the first temperature measuring unit 13 and the second temperature measuring unit 14 to control the temperature in the cross sectional direction of the furnace 10.

That is, the simulation reactor 10 is provided with a first temperature measurement unit 13, a second temperature measurement unit 14, and a temperature control unit (not shown) for controlling the temperature inside the simulation reactor 10 15 may be provided.

That is, it is preferable that the shield tube 13b is formed of a material having heat resistance, wear resistance, and thermal conductivity, and is provided long in the longitudinal direction (y) of the simulation reactor 10.

The shield tube 13b may be formed to have a smaller sectional area from the upper end 11 to the lower end 12 of the simulation reactor 10. In addition to the structure for deforming the shape of the inside of the simulation reactor 10 as described above, the shape of the shield tube 13b inserted into the simulation reactor 10 may be modified, So that the size of the hollow inside the furnace 10 is increased from the upper end 11 to the lower end 12. Thus, the fact that the sample (s) can be smoothly moved has been described above.

The second temperature measuring unit 14 may be provided on the outer surface of the simulation reactor 10 to measure the temperature. This is because the first temperature measuring unit 13 measures the temperature inside the simulated reaction furnace 10 and the second temperature measuring unit 14 measures the temperature outside the simulated reaction furnace 10, So that the temperature distribution in the cross-sectional direction (x) of the simulated reaction furnace 10 is formed similarly to the actual blast furnace.

The rotating plate 51 is provided with a top opening so as to contain the sample s discharged from the simulation reactor 10 and the sample s can be separated by a centrifugal force. A portion of the side surface may be provided in an open cylinder shape.

The sample discharging means 50 provides the driving unit 52 and the rotating plate 51 so that when the sample s flows into the open top surface of the rotating plate 51, The sample s is also rotated by the driving unit 52 so that the sample s is also subjected to the centrifugal force so that the sample s can be discharged to a part of the opened side of the rotating plate 51.

Here, by regulating the rotation speed of the rotary plate 51, the amount of the discharged sample s can be adjusted by adjusting the centrifugal force received by the sample s.

That is, although the sample s discharged from the simulation reactor 10 may be discharged only by the load of the sample s itself, it is difficult to control the discharge amount. In the present invention, the sample discharging means 50 ).

Specifically, since the sample (s) is continuously solidified or closely adhered, when the lower sample (s) is discharged, the upper sample (s) can also be continuously moved downward.

Therefore, if the speed at which the sample discharging means 50 discharges the lower sample s by the centrifugal force is adjusted, the discharging speed of the entire sample s in the simulating reactor 10 can be adjusted.
