The desulfurizer uses dry desulfurization.
The chimney is equipped with measurement of soot and dust concentration instrument and gas vent sulfur content detector.
The outlet of the desulfurizer is equipped with bypass line, and bypass line is equipped with the second valve.
Technological process is as follows：Dedusting gas from coke dry quenching body is by the vacuum suction of dedusting fan through pipe influx
Into one, sack cleaner dedusting is entered after dedusting manifold cools into heat accumulating type cooler, the gas warp after dedusting
Enter desulfurizer after dedusting fan pressurization and carry out desulfurization, the gas after desulfurization is emitted into air through chimney.
The beneficial effects of the utility model are：There is high dust collection efficiency using sack cleaner, floor space is small, to dust-laden
The advantages that low dust treatment effect of rate is good.According to the process characteristic of dry coke quenching ground station for dust removal, preferably desulfurizer is arranged in
The rear portion of dedusting fan, it is excellent preferably to select suitable for the relatively low dry desulfurization of high-temperature gas and sulfide concentration, such as activity
Charcoal method, iron oxide process and zinc oxide method etc., dry desulfurization is also with flow is simple, energy consumption is low, does not produce waste water and desulfuration efficiency
The advantages that high.The dry coke quenching dedusting gas handled by the device complies fully with《The industry of GB 16171-2012 coking chemistries is dirty
Contaminate thing discharge standard》Environmental requirement in the middle, and the sulfide recycled can send to the ammonium sulfate workshop section in coking recovery of chemical products workshop
Change into ammonium sulfate so that waste utilization, its economic benefit is improved in the case where meeting the requirement of environmental protection.
