Abstract

PURPOSE:To safely discharge dust while preventing the hanging of dust by discharging dust from a dust bin in such a state that the inside of the dust bin is reduced to the pressure somewhat higher than the atmospheric pressure. CONSTITUTION:A control means 15 for discharging a dust bin is closed and a pressure equalizing valve 9 is opened and thereby a pressure equalizing state is obtained and thereafter dust 7 is discharged to a dust bin 6 from dust removal chambers 1 by opening the control means 4 for discharging the dust removal chambers. Then after closing the control means 4, the pressure equalizing valve 9 is closed and thereby the discharge of dust 7 to the dust bin 6 from the dust removal chambers 1 is stopped. Thereafter in case of reducing the pressure inside the dust bin 6 by opening and closing a pressure discharge valve 11 of the dust bin, the evacuation is stopped in such a state that it is reduced to the pressure somewhat higher than the atmospheric pressure and dust 7 is discharged from the dust bin 6 in this state little higher than the atmospheric pressure and dust 7 is discharged from the dust bin 6 in this state. As a result, the discharge of dust 7 can be safely performed while preventing the hanging of dust.

After rough dust removal in step 2, the blast furnace gas is supplied to the furnace top pressure power generation equipment 25 through a dry dust collector Wi 24 like a bag filter attached to a wet dust collector 23, and the energy of the blast furnace gas is recovered as electricity. .

Dust removal chamber 1 of such a blast furnace gas dust collector @24
When discharging dust from the dust bin 6 to the pug mill 16, if the dust in the dust bin 6 and the pressure gas are discharged at the same time, the dust bin discharge control means will wear out, and the gas seal may become impossible in a short period of time, or the case may become damaged. Accidents such as holes may occur. On the other hand, fluctuations in the dust flow rate become large, making control difficult. In order to prevent this, a method has been proposed in which the gas inside the dust bin 6 is released, the inside of the dust bin 6 is brought into an atmospheric pressure state, and the dust is discharged from the inside of the dust bin 6.

In this case, if you are discharging dust from the dust bin 6 with the pressure release valve that releases the gas in the dust bin 6 open, air will be sucked into the dust bin 6 and oxygen will be supplied to the dust bin 6. This could result in a dangerous situation such as an explosion, so it is necessary to close the pressure relief valve after releasing the gas pressure.

(Problem to be solved by the invention) However, when the dust is discharged from the dust bin with the pressure relief valve closed, the inside of the dust bin becomes negative pressure due to the volume change due to the discharge of dust, and only the lower part of the dust inside the dust bin is discharged. There is a problem in that a dust shelf phenomenon occurs in which the upper part of the dust remains in a shelf shape, making it impossible to discharge the dust.

Therefore, in order to prevent ledges when discharging dust, a technique has been proposed in JP-A-51-145976, in which the dust is discharged by equalizing the pressure between the dust hopper and the transport pipe during suspension of operation. In this case, suction is carried out by a vacuum pump, which prevents shelf-situation during normal operation, but unlike the dust collector of a blast furnace, a vacuum pump is not used, and the pressure is always above atmospheric pressure, which is frequently used during blast furnace operation. This method has the problem that it cannot be applied to equipment that discharges dust.

Furthermore, in order to prevent dust from adhering to the seal valve and gas leakage, a technique for injecting high temperature, high pressure inert gas into the seal valve was proposed in JP-A-59-147659; Since the above is not taken into account, the problem is that the problem is that it only encourages the occurrence of ledges and cannot prevent them.

(Means for Solving the Problems) - In order to achieve the above object, the present invention discharges dust from the dust removal chamber of the dust collector to the dust bin via the dust removal chamber discharge control means, and then controls the discharge from the dust bin to the dust bin. In the method for discharging dust from a dust collector configured to discharge dust through means, the dust bin control means is closed when discharging dust from the dust removal chamber to the dust bin, and a pressure equalization valve is provided to equalize the pressure between the dust removal chamber and the dust bin. The dust removal chamber discharge control means is opened to obtain an equal pressure state, and the discharge of dust from the dust removal chamber to the dust bin is stopped by closing the dust removal chamber discharge control means and then closing the pressure equalization valve. Further, the dust is discharged from the dust bin by opening the exhaust pressure valve provided in the dust bin to reduce the pressure inside the dust bin to a high pressure state, and then closing the exhaust pressure valve and opening the dust bin control means. It is characterized by

(Function) After discharging the dust from the dust removal chamber into the dust bin, the dust inside the dust bin is discharged without reducing the pressure inside the dust bin to atmospheric pressure, so that the dust is pressurized in the discharge direction. Therefore, no shelf phenomenon occurs. In addition, by stopping the discharge of gas inside the dust bin at a state slightly higher than the outside air, the internal pressure gradually decreases as the dust is discharged, and at the final stage of dust discharge, the pressure inside the dust bin is reduced to a state close to atmospheric pressure. High-pressure gas is not exhausted at high speed along with dust.
