Adsorption tower of dry exhaust gas treatment device

An adsorption tower used in an exhaust gas dry treatment device having an adsorption tower for adsorbing and removing the harmful components contained in an exhaust gas, using a granular adsorbent, which adsorbent tower comprises

• a box-shaped tower body,
• a horizontal partition plate of predetermined length formed in the tower body from a front tower wall toward a rear tower wall over the total width of the front tower wall,
• a plurality of reaction chambers which are vertically formed between the horizontal partition plate and the rear tower wall from a tower top wall to a tower bottom wall and which have moving beds therein,
• lower partition plates formed in a lower tower body below the horizontal partition plate so as to alternately close the openings between the ends of reaction chambers and, as necessary, the openings between the ends of reaction chambers and a tower inner wall,
• upper partition plates formed in an upper tower body above the horizontal partition plate so as to alternately close the openings between the ends of reaction chambers and, as necessary, the openings between the ends of reaction chambers and the tower inner wall, wherein no upper partition plate being installed above the lower partition plates and no lower partition plate being installed below the upper partition plates,
• an exhaust gas supply port allowing the inside of an inlet side wind box space which is formed in the tower body below the horizontal partition plate, to communicate with the inside of an exhaust gas supply duct, and an exhaust gas discharge port allowing the inside of an outlet side wind box space which is formed in the tower body above the horizontal partition plate, to communicate with the inside of an exhaust gas discharge duct.

An adsorption tower used in an exhaust gas dry treatment device having an adsorption tower for adsorbing and removing the harmful components contained in an exhaust gas, using a granular adsorbent, which adsorbent tower comprises a first adsorption tower and a second adsorption tower installed above the first adsorption tower, the first adsorption tower and the second adsorption tower each comprising

• a box-shaped tower body,
• a plurality of reaction chambers which are vertically formed in the tower body so as to extend from a front tower wall side toward a rear tower wall facing the front tower wall and from a tower top wall to a tower bottom wall while being separated from the front tower wall by a predetermined distance, and which have moving beds therein, and
• vertical partition plates installed so as to alternately close the openings between the ends of each two facing reaction chambers at the front tower wall side and, as necessary, vertical partition plates installed so as to close the openings between the ends of reaction chambers at the front tower wall side and a tower inner wall,
• and which adsorption tower further comprises
• at least one connecting duct allowing the inside of at least one closed space formed in the first adsorption tower body by two facing reaction chambers, the rear tower wall and one vertical partition plate, to communicate with the inside of at least one closed space formed in the second adsorption tower body by two facing reaction chambers, the rear tower wall and one vertical partition plate,
• an exhaust gas supply port allowing the inside of an inlet side wind box space formed in the first adsorption tower body between the front tower wall and the vertical partition plates, to communicate with the inside of an exhaust gas supply duct, and
• an exhaust gas discharge port allowing the inside of an outlet side wind box space formed in the second adsorption tower body between the front tower wall and the vertical partition plates, to communicate with the inside of an exhaust gas discharge duct.
