Claims

[Scope of utility model registration request]

(1) An adsorption device that brings exhaust gas into contact with a granular carbon-based adsorbent to adsorb and remove the sulfur dioxide gas contained therein, and heats the carbon-based adsorbent that has adsorbed sulfur dioxide gas to expel the sulfur dioxide gas and regenerate the carbon-based adsorbent. In a dry desulfurization device equipped with a desorption device and a reduction device that brings sulfur dioxide gas expelled from the desorption device into contact with a carbon-based reducing agent to reduce it to sulfur,
Dry desulfurization characterized in that an indirect contact heat exchanger is provided between the desorption device and the reduction device to raise the sulfur dioxide gas expelled from the desorption device to the reduction reaction starting temperature in the reduction device. Device.

(2) Scope of Utility Model Registration The dry desulfurization device according to claim 1, characterized in that the heat source of the indirect contact heat exchanger is the combustion heat of reducing agent residue discharged from the reducing device.

(3) In claim 1 of the utility model registration claim, the heat source of the indirect contact heat exchanger is a dry type heat exchanger characterized in that the heat source of the indirect contact heat exchanger is the combustion heat of fine particulate adsorbent separated and removed from an adsorption device or a desorption device. Desulfurization equipment.

(4) Scope of Utility Model Registration Claims In paragraph 1, the heat source of the indirect contact heat exchanger is collected by a dust collection device provided for processing clean exhaust gas after adsorption and removal of sulfur dioxide gas discharged from an adsorption device. In Claim 1, the heat source of the indirect contact heat exchanger is the heat of combustion of the particulate adsorbent produced by the reduction device. Dry desulfurization equipment characterized by heat.
