Abstract

An efficient turn-back type SDS (sodium dodecyl sulfate) desulfurization tower device belongs to the technical field of flue gas desulfurization and purification. The device comprises an inlet compensator, an inlet flue, a first ascending bin ash bucket, a spraying hole, a first ascending bin, a flow guide plate, a communication opening, a flow guide plate, a descending bin, a descending bin ash bucket, a communication opening, a flow guide plate, a second ascending bin, a second ascending bin ash bucket, a flow guide plate, an outlet compensator, an ash discharging valve, a level gage, a vibrator, an access hole, a first partition plate and a second partition plate. The device has the advantage that the problems of short contact time of flue gas and a desulfurizing agent, low desulfurization efficiency, poor matching effect with a dust removal system and the like in a sodium-based dry desulfurization system are solved.

Description

technical field [0001] The invention belongs to the technical field of flue gas desulfurization and purification, and in particular provides a high-efficiency switchback type SDS desulfurization tower device, which is suitable for SDS sodium-based dry desulfurization systems. The device is designed to solve the problems of short contact time between flue gas and desulfurizer, low desulfurization efficiency, and poor matching effect with the dust removal system in the sodium-based dry desulfurization system. Background technique [0002] SDS sodium-based dry desulfurization technology mainly uses NaHCO 3 Strong activity characteristics, widely used in steel industry gas boilers, hot air stoves, coking furnaces, biomass boilers, waste incinerators and other exhaust gas SO 2 In the flue gas working condition with low content and moderate flue gas temperature, the sodium-based powder activates thermal decomposition under the action of high-temperature flue gas, and the SO in th...
