The Cloth Dust Removing And Desulphurization Technology Application Research

Coal-fired boiler exhaust emissions,caused great damage to the current environment,especially the problem in north China.To solve this problem,the state,provinces,cities and developed the related environmental protection policies.These policies,to towns across heating engineering constraint was proposed,also made contributions to the local environmental protection.Kailuan tangshan money community service center set up camp living community coal-fired boiler room two 20 t/h coal-fired boiler,face the reality of outdated equipment,emission exceeds bid badly,the flue gas desulfurization dust removal.In this paper,from the technology revamping scheme selection,design,equipment selection,sulfur removal effect calculation and renovation project economic accounting of the sulfur removal of the reconstruction project comprehensive design research work.Results show that the area do not have central heating heat source,and no gas protection,according to local conditions and policy conditions,flue gas desulfurization dust removal renovation is the only appropriate solutions.On the basis of clear the decision scheme,according to the boiler room process design was carried out on the existing conditions and market conditions,formed the cloth bag dust removal with limestone/gypsum desulfurization process,the theoretical calculation shows that the technology can meet the requirements of the boiler room,and can be fully realized "boiler air pollutant emission standard" regulation of emissions limits.On the basnt performance indicators.On the specific process,the original spray type dust removal desulfurization towis of process design,choose the appropriate equipment,accounting for all sorts of equipmeer desulfurization system for cloth bag dust catcher system,realized the sulfur removal way of change.After bag dust removal desulfurization renovation of money home living community coal-fired boiler room,began putting-in-service proactively in the winter of 2015,after a heating season running show that the emission indexes have reached the design requirements,operation cost is increased before modification.But as a result of emissions targets up to the national,regional relevant environmental standards,to the enterprise to save a large amount of pollutant discharge fee each year,investment in equipment is fully recycled through a heating season.
