The present invention relates to a sintered flue gas adsorption tower control device, and more particularly, to detect the differential pressure in each adsorption tower and to control the residence time of activated carbon in the adsorption tower by increasing or decreasing the amount of activated carbon in the roll feeder under the adsorption tower to correspond to the differential pressure state. It relates to a sintered flue gas adsorption tower control device.

As shown in FIGS. 1 and 2, the activated carbon circulation control device of the conventional sintered flue gas adsorption tower includes SOx, NOX, dioxin, etc., which are harmful gases contained in the sintered flue gas in the activated carbon pores by densely packed activated carbon. Adsorption tower (7) for adsorption filtration, a roll feeder (10) for discharging contaminated activated carbon in the adsorption tower (7) at a constant speed, a hopper (11) for temporarily storing activated carbon discharged from the roll feeder (10), and , A bucket conveyor 14 for transporting the contaminated activated carbon to the regeneration tower, a bucket conveyor (13, 14) for transporting the healthy activated carbon to the adsorption tower (7) after desorbing the contaminated activated carbon from the regeneration tower, and the activated carbon of the adsorption tower (7). It consists of the level meter 9 which detects a level, the tripper 13a which adjusts the amount of activated carbon granularity according to the level state of activated carbon, and the rotary valve 8 which loads activated carbon in the said adsorption tower 7.

Then, in the operating system 100, the retention time of activated carbon in the adsorption tower 7 and the average level of the adsorption tower 7 are set. The above-mentioned retention time is a time from when the activated carbon is introduced into the upper part of the adsorption tower 7 and immediately before the discharge to the lower roll feeder 10. That is, it means the time for the activated carbon to adsorb and filter the sox, SOx, NOX, dioxin, etc. which are noxious gases in the adsorption tower 7.

Therefore, the speed of the roll feeder 10 is determined by the set residence time in the operating system 100. If the set residence time is large, the speed of the roll feeder 10 is slow, and if the residence time is short, the roll feeder 10 The speed is fast.

In addition, the process of adsorbing harmful gases in the sintered flue gas will be briefly described. As shown in FIGS. 1 and 2, the sintered flue gas generated when the sintered ore is generated in the sintering machine passes through the electrostatic precipitator 1 to collect dust. After removal, when the pressure is blown through the main blower 3 to a weakened state (about 0 mmH ₂ O), the weakened sintered flue gas is boosted by a boost-up fan 5 to absorb the adsorption tower 7. Will blow air.

Then, the sintered flue gas introduced into the adsorption tower 7 collects harmful gas contained in the flue gas while passing through the activated carbon layer.

In addition, the reaction in which the activated carbon in the adsorption tower 7 adsorbs harmful gases contained in the sintered flue gas is as follows.

SOX catalysis

1) SO ₂ + 1 / 2O ₂ + H ₂ O → H ₂ SO ₄ (sulfuric acid)

2) H ₂ SO ₄ + NH ₃ → NH ₄ HSO ₄ (ammonia salt)

NOX catalysis

1) NO + NH ₃ + 1/4 O ₂ → N ₂ + 3 / 2H ₂ O (nitrogen + water)

2) Dioxin and Dust Filtration

Therefore, the gas discharged to the stack (not shown) after passing through the adsorption tower 7 is the clean gas from which noxious gas is completely removed to the stack.

The polluted activated carbon which collects the harmful gas and the dust contained in the exhaust gas is lowered from the upper portion of the adsorption tower 7 to the lower portion at a speed corresponding to the residence time set by the driver in the operating system 100 and the roll feeder 10. By the discharge to the hopper 11, the discharged activated carbon is conveyed to the regeneration tower through the bucket conveyor (14). Subsequently, a high temperature of 400 ° C. or higher is used to desorb sulfuric acid (H ₂ SO ₄ ), ammonia salt (NH ₄ HSO ₄ ), etc. catalyzed by the pores of the activated carbon, and then regenerate them in a healthy state. We carry in (7).

In addition, the activated carbon conveyed to the adsorption tower 7 using the bucket conveyors 13 and 14 calculates an average level of the adsorption tower 7 set by the driver in the operating system 100 and a detection signal of the level meter 9. Each tripper 13a is operated on the activated activated carbon of the corresponding adsorption tower 7 to keep the activated carbon level of the adsorption tower 7 constant.

That is, the discharge amount and the input amount of activated carbon in the adsorption tower 7 are almost constant in an amount corresponding to the residence time set by the driver in the operating system 100, and the amount of circulation consumed when the adsorption tower 7 and the regeneration tower are circulated. About 2% activated carbon is replenished externally.

And the harmful gas and dust content of the flue gas generated during the sintering operation has a large difference depending on the sintering operation situation or the dust collection state of the electrostatic precipitator (1).

However, since the discharge amount of the roll feeder 10 is always constant at a speed corresponding to the residence time set by the driver in the operating system 100, the sintering operation situation or the dust collecting state of the electric precipitator 1 is good, and the harmful gas of the exhaust gas is good. And even when the dust content is low, since the activated carbon is constantly discharged from the roll feeder 10, there is a problem in that expensive carbon (millions of won per ton) of activated carbon is excessively consumed.

In addition, when there is a high harmful gas and dust content of the exhaust gas in the operating situation or poor dust collection state of the electrostatic precipitator (1), there is a problem that the facility must be stopped due to the air permeability decrease due to excessive clogging of activated carbon pores and activated carbon layer in the adsorption tower (7). .

In addition, the gate of the roll feeder 10 causes partial blockage due to the removal of foreign substances and mechanical parts of the facility, and the activated carbon in the blocked portion forms a stagnant layer in a state in which discharge is impossible.

In particular, when the stagnant layer of activated carbon is expanded as described above, and the stagnant layer is left for a long time, SOx, moisture, etc., in which activated carbon having high carbon content is contained in the sintered flue gas, is generated by heat of oxidation when reacting with sulfuric acid and carbon dioxide. In addition, there is a problem in that activated carbon damage as well as the spread of fire accidents and equipment accidents due to excessive temperature rise to several hundred ℃.

Meanwhile, reference numerals 6 and 12, which are not described in FIG. 1, represent inlet chambers and outlet chambers, respectively.

The present invention was created to solve the above problems, by detecting the differential pressure in each adsorption tower and controlling the speed of the roll feeder corresponding to the differential pressure state by adjusting the residence time of activated carbon in the adsorption tower to reduce the consumption of activated carbon and equipment Improves the utilization rate of the activated carbon, detects the circulation of activated carbon, and indirectly determines the blockage of the gate of the roll feeder with the detection signal, and controls the increase in the amount of activated carbon discharged from the roll feeder when a certain deviation occurs. The purpose of the present invention is to provide a sintered flue gas adsorption tower control device that prevents accidents and spreads due to ignition of activated carbon by preventing and recognizing the driver with an alarm and stopping the facility when an abnormal deviation occurs.

Meanwhile, reference numeral 34b, which is not described in the drawings, shows a roller, 40 a pressure gauge, 51 a chain, and 52 a rail.

Referring to the operation of the sintered flue gas adsorption tower control device according to the present invention having the configuration as described above are as follows.

Referring back to the drawings, first, the pressure gauge 700a of the pressure detector 700 is installed on the inlet and outlet of each adsorption tower 27 to detect the pressure. In addition, the load cell 42 of the metering unit 800 detects the weight applied when the roller 34b of the bucket 34a on which the activated carbon is loaded moves the upper portion of the load cell rail 42a and transmits an electric signal corresponding thereto. Output converted

The sebum 42g of the metering unit 800 detects the signal when the bucket 34a on which activated carbon is loaded passes the installation site of the sebum 42g, and outputs the signal as a pulse signal.

In addition, the first operator 900a of the activated carbon circulating amount control unit 900 calculates and outputs a signal input from the pressure gauge 700a of the pressure detector 700 as a differential pressure signal of each adsorption tower 27.

In addition, the ratio controller 900b of the activated carbon circulation control unit 900 calculates and outputs a ratio corresponding to the management pressure of the adsorption tower and the residence time signal of the activated carbon set by the operating system 100.

In the ratio control method, a signal corresponding to the set residence time of activated carbon is initially output, and the deviation value is compensated to the initial output value when a deviation between the set pressure signal of the adsorption tower and the differential pressure signal input from the first operator 900a occurs.

In addition, the second operator 900a 'of the activated carbon circulating amount control unit 900 is a signal input from the load cell 42 and sebum 42g of the metering unit 800 to calculate a signal corresponding to the hourly feed amount of the bucket conveyor 34. Output

The comparator 900d of the activated carbon circulating amount control unit 900 is a roll feed back from the feed amount signal of the bucket conveyor 34 of the second operator 900a 'and the speed control means 500a of the motor control unit 500. The rotation speed of the feeder 30 is compared to generate an alarm or stop the facility together with the output of the deviation corresponding to the deviation to the adder 900c when the deviation occurs.

The adder 900c of the activated carbon circulation amount control unit 900 further outputs the input signal of the ratio controller 900b and adds and outputs the signal input from the comparator 900d.

And the management pressure of the adsorption tower 27 in the operating system 100 is set to a value corresponding to the differential pressure applied to the adsorption tower in the normal operating state.

In addition, the activated carbon residence time in the operating system 100 is set to a value corresponding to the differential pressure applied to the adsorption tower 27 in a steady operating state to maintain stable operation.

When the sintered flue gas generated during the sintering operation is boosted by the boost-up fan 25 and then introduced into the adsorption tower 27, a ratio corresponding to the management pressure of the adsorption tower 27 set by the operating system 100 and the activated carbon residence time signal are obtained. When the output signal is transmitted to the speed control means 500a of the motor control unit 500 through the adder 900c, the corresponding power signal is output to drive the roll feeder 30.

In addition, the activated carbon in the adsorption tower 27 starts to descend by the driving of the roll feeder 30, and discharge is started to the lower hopper 31. The discharged activated carbon is loaded into the bucket conveyor 34 to the regeneration tower. Is carried.

When the sintered flue gas flows into the adsorption tower 27, it is applied to the inlet side and the outlet side of each adsorption tower 27, and the pressure gauge 700a of the pressure detector 700 detects the respective pressures and transmits the signal to the activated carbon circulation control unit ( Input to the first operator (900a) of 900, the differential pressure applied to each adsorption tower 27 is calculated and output to the ratio controller (900b).

In addition, the ratio controller 900b to which the differential pressure signal is input compensates the deviation value to the initial output value when the deviation between the management pressure signal of the set adsorption tower 27 and the differential pressure signal input from the calculator 900a occurs, and outputs it to the adder 900c. And, the signal input to the adder (900c) is input to each speed control means (500a) of the motor control unit 500 to control the rotational speed of the roll feeder 30 to adjust the discharge of activated carbon.

In other words, due to deterioration of the sintering operation state or poor dust collection state of the electrostatic precipitator 31, the sintered flue gas contains a lot of dust and noxious gas, so that the differential pressure of each adsorption tower 27 calculated by the first operator 900a increases. By increasing the rotational speed of 30), the descending speed of the activated carbon in the adsorption tower 27 is increased to improve the air permeability of the activated carbon, thereby lowering the set pressure of the adsorption tower 27.

When the differential pressure applied to the adsorption tower 27 is lower than the control pressure set value due to the stopping of the sintering machine or the stabilization of the sintering operation state, etc., the rotation speed of the roll feeder 30 is decreased to slow down the descending speed of the activated carbon in the adsorption tower 27. The consumption of expensive activated carbon is prevented by reducing the circulation amount of.

In addition, the weight of the bucket 34a loaded with the activated carbon of the bucket conveyor 34 during the movement of the 'C' part of FIG. 3 during transportation to the regeneration tower is detected by the load cell 42. The bucket 34a is detected by the sebum 42g and the signal is outputted to the second operator 900a 'of the activated carbon circulation control unit 900.

In addition, a signal corresponding to the hourly feed amount of the bucket conveyor 34 is output to the comparator 900d as a signal of the load cell 42 and sebum 42g input to the second operator 900a 'of the activated carbon circulation control unit 900. When the rotation speed of the roll feeder 30 fed back from the speed control means 500a of the motor control unit 500 is compared, the output is not generated when the first deviation occurs, and when the deviation occurs between the first deviation and the second deviation. The compensation value corresponding to the deviation is added to the adder 900c and added to the existing output value by the adder 900c to output the value to the speed control means 500a to increase the rotational speed of the roll feeder 30. Raise an alarm.

In addition, when the occurrence deviation of the comparator 900d is greater than or equal to the second deviation, the roll feeder 30 is stopped.

That is, when the output signal of the operator 900d and the feedback signal from the speed control means 500a compare the signal from the comparator 900d to the first deviation or less, the gate of the roll feeder 30 is determined to be in a normal state. When the first deviation is less than or equal to the second deviation, a part of the gate of the roll feeder 30 is blocked to determine the formation of the fixed layer of activated carbon as a start step, thereby increasing the rotational speed of the roll feeder 30 to solve the fixed layer. Although the rotation speed of the roll feeder 30 is increased to solve the fixed layer of the activated carbon, when the second deviation or more occurs, the blockage of the gate of the roll feeder 30 is diffused to determine that the fixed layer of activated carbon is spread. (30) is stopped.

As described above, the apparatus for controlling sintered flue gas adsorption tower according to the present invention has the following effects.

By controlling the circulation of activated carbon due to the differential pressure of the adsorption column, it is possible to prevent excessive consumption of expensive activated carbon, thereby contributing to cost reduction.

In addition, by maintaining the stabilization differential pressure of the adsorption tower to improve the operation rate of the equipment, it is possible to prevent equipment accidents due to the ignition of activated carbon.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
