<p>PURPOSE:To carry out the adsorption and removal of hydrogen sulfide and reproduction of adsorbent by a single tower treatment by providing a water removing plate part between an upper adsorbent packing layer and a lower water sprinkler to collect the regenerated water discharged from the upper adsorbent packing layer and to discharge to the outside of the device. CONSTITUTION:Two layers 2A, 2B packed with hydrogen sulfide adsorbent are provided at the upper and lower parts with a distance between in a single treatment vessel 1, and the gas contg. hydrogen sulfide is continuously passed through the layers 2A, 2B, and the layer packed with hydrogen sulfide adsorbent which is deteriorated in adsorption capacity due to the adsorption of hydrogen sulfide is selectively regenerated. For this purpose, the sprinklers 3A, 3B selectively sprinkling the water for regeneration are provided above each layer, and a bottom water discharge system 7B is provided under the layer 2B to discharge the water for regeneration to the outside of the vessel, while the water removing plate part 4 is disposed between the layer 2A and the lower sprinkler 3B to collect the water for regeneration from the layer A into the water removing plate part 4, from which the water is discharged through an intermediate water discharge system 7A to the outside of the vessel.</p> |
