Abstract

Wet Combustion Gas Sulfur Removal Equipment The removal of sulfur from combustion gases is achieved through the contact between the gas/liquid phase of the combustion gas and the absorbent slurry. Specifically, the stage had revealed the total absorption tower that consisted of Absorbent slurry tank Thickening tank that serves to intensify the slurry. The reaction products formed by the reaction of the adsorbent and SO2 contained in the combustion gas fall to the bottom. The adsorption section above the tank for interphase contact. Combustion gas/liquid gases and slurries, adsorbents and also for sulfur removal reactions and the chimney above such adsorption section serving for dispersing gas from The treated combustion enters the atmosphere. The adsorption part has a nozzle. for injecting sherry adsorbent in an upward direction and the gas from such combustion was introduced into the lower end of the section. Such adsorption and the adsorbent slurry injected through the nozzle will cause contact between the gas/liquid and the non-reactive absorbent slurry and slur. product storage The reaction will fall into the aforementioned liquid tank. The reaction product slurry is then taken from the tank into the thickening tank.

Claims (4)

1. A device to remove sulfur from gas from wet burning, which removes sulfur from combustion gas. It is made in such a way that there is contact between the gas / the combustion gas liquid and the sorbent slurry. The device consists of a combined adsorption tower. Within this single section there is a liquid tank with slurry, sorbent, thickening tank. In which the reaction product between the adsorbent and SO2 contained in the combustion gas was concentrated with agreement. Adsorption part Above the tank Such liquid And is where the sulfur removal reaction occurs by interphase contact. Gas / liquid gas from combustion and sorbent sorbents. The nozzle at the lower end of the adsorption section is positioned directly above the liquid surface. For injecting sorbent sorbent in the direction above. And the chimney above the adsorption section, which serves to distribute the treated combustion gas into the atmosphere. The combustion gases introduced into the lower end of the adsorption section and the sorbent slurry injected through the nozzles come into contact. As for the slurry, the inactive adsorbent and slurry, the reaction product falls and is collected in the tank into the thickening tank. And the rich sludge was removed from the thickened tank. 2. The equipment for removing sulfur from gases from wet combustion according to claim 1, the thickening tank is made by dividing a part of the liquid tank mounted at the bottom of the suction tower. Such a combined liner with a baffle with a hole in the pad. To allow serrine, the reaction product to flow from the liquid tank into the thickening tank. 3. Equipment for removing sulfur from wet combustion gas according to claim 1, in which silo, sorbent and disperser for dispersing sorbent powder and allowing the sorbent powder to enter the adsorption section. Will be installed on the adsorption section. And the sorbent powder that is supplied to the adsorbent solo by air transport. Will be distributed in the adsorption section by the diffuser Causing the absorbent powder to fall It comes into contact with Slerry and is captured by Slerry in the adsorption section. 4. Equipment for removing sulfur from wet burning gas according to one of the claims 1 to 3, where the flue contains a mist arrester.
