The hot air supplied from the burner 50 while the activated carbon passes through the regenerator 10 heats the activated carbon to separate the foreign matter adsorbed on the activated carbon from the activated carbon and the separated activated carbon is stored in the discharge reservoir 32 And then is returned to the adsorption section.

The hot air supplied into the regeneration tower 10 by the burner 50 is discharged to the outside of the regeneration tower 10 after heating the activated carbon.

The activated carbon heated in the regeneration tower 10 is cooled while falling down from the inside of the regeneration tower 10. The activated carbon is cooled by the outside air flowing into the regeneration tower 10 and the high temperature air Is supplied to the storage tank (30) along the preheating part (80).

Therefore, the activated carbon supplied into the regeneration tower 10 is preheated while being in contact with the hot air supplied along the preheating unit 80, so that the activated carbon can be easily heated by the hot air supplied from the burner 50.

Thereby, the regeneration efficiency of the regenerator 10 is improved, and the amount of fuel required in the burner 50 can be reduced.

Further, when the regeneration efficiency is improved, the concentration of foreign matter discharged from the regeneration tower 10 is increased, so that the concentration of SOx required by the sulfuric acid plant can be achieved, so that the foreign substances discharged from the regeneration tower 10 can be utilized in the sulfuric acid plant do.

The regeneration tower 10 is provided with a heating section 12 for heating activated carbon supplied from an input stocker 30 while passing hot air supplied from the burner 50 and a heating section 12 for cooling the activated carbon passing through the heating section 12 And a blowing pipe 16 for supplying outside air to the cooling unit 14 by the operation of the first blowing fan 18.

A heating section 12 for heating the activated carbon is disposed in the upper part of the regenerator 10 while hot air supplied from the burner 50 is passed through the regenerator 10. In the lower part of the regenerator 10, And a cooling section 14 for cooling and moving to the next process is located.

The cooling unit 14 is connected to a lower end of the cooling pipe 14 to supply external air to the cooling unit 14 and a first blowing fan 18 is installed in the lower pipe 16.

The outside air supplied to the cooling unit 14 along the inlet pipe 16 absorbs the heat while being in contact with the activated carbon to perform a cooling operation and is supplied to the input storage unit 30 along with the preheating unit 80, ) Of the activated carbon.

The burner 50 can heat the activated carbon passing through the heating unit 12 to a temperature higher than the set temperature even if the burner 50 supplies the regeneration tower 10 with a relatively low temperature high temperature air using a small amount of fuel .

A discharge pipe 90 for discharging foreign matter separated from activated carbon to the outside of the regenerator 10 is provided between the heating unit 12 and the cooling unit 14 and a second blower fan 92 is installed to the discharge pipe 90 do.

The activated carbon passing through the heating unit 12 is heated up to 400 to 450 degrees to separate the SOx from the foreign substances contained in the activated carbon. The SOx separated from the activated carbon is discharged to the discharge pipe 90 by the operation of the second blowing fan 92, To the outside of the regeneration tower 10.

The preheating unit 80 includes a preheating pipe 82 for supplying the hot air discharged through the heating unit 12 to the input stocker 30 and the hot air passing through the input stocker 30, And a discharge pipe (84) for guiding it to the outside.
