Abstract

The invention discloses a sulfur resource recovery method and device making incineration, resolution, charcoal head reduction coordinated. The sulfur resource recovery device comprises a resolution tower, an incineration furnace and a fluidized bed carbon thermal reduction tower, wherein the resolution tower is divided into a preheating section, a resolution section and a cooling section from topto bottom, the bottom of the incineration furnace is connected with a tail heated device, and the tail heated device is sequentially provided with a primary air heater, a secondary air heater, a mixedreaction gas heater from bottom to top. A tube nest outlet of the cooling section is connected with a gas inlet of the secondary air heater, a gas outlet of the secondary air heater is connected witha tube nest inlet of the resolution section, the tube nest outlet of the resolution section is connected with the tube nest inlet of the preheating section, the tube nest outlet of the preheating section and the gas outlet of the primary air heater are both connected with an air inlet of a combustor of the incineration furnace, a resulted gas outlet of the resolution tower is connected with a gasinlet of the mixed reaction gas heater, and a gas outlet of the mixed reaction gas heater is connected with a resulted gas inlet of the fluidized bed carbon thermal reduction tower.

Description

technical field [0001] The invention belongs to the field of air pollutant control and resource utilization, and in particular relates to incineration heating, active coke analysis and charcoal thermal reduction of SO 2 Sulfur resource recovery device and process coordinated by the three processes of preparing sulfur. Background technique [0002] In view of the current development trend of environmental protection technology, resource-based and sustainable coal-fired flue gas SO 2 The removal process is becoming the development direction of the current environmental protection technology. Currently the most widely used SO 2 The removal technology is limestone wet desulfurization technology. This technology consumes a large amount of limestone resources and water resources. The utilization rate of the by-product desulfurization gypsum is low, and the desulfurization wastewater is difficult to treat. It brings a large amount of wastewater and waste solid discharge, causing ...
