Background technology
At present, the waste gas that from boiler, ejects enters atmosphere after passing through purified treatment usually.And entrained waste heat has also slatterned in the flue gas.Simultaneously, brown coal because of water content up to 35-40%, and calorific value has only 2500-3500kc/kg usually, so efficiency of combustion is on the low side, the investment of main frame subsidiary engine is bigger, the integrated purification investment of the out of stock demercuration of flue gas desulfurization is big, cost is high.
Summary of the invention
The application's goal of the invention is that the heat that solves the flue gas that from boiler, ejects is not effectively used, brown coal utilization ratio problem of lower, and a kind of gas cleaning and the compound system of brown coal upgrading are provided.
In order to realize the purpose of the utility model, the utility model adopts following technical scheme:
A kind of gas cleaning of the utility model and the compound system of brown coal upgrading; It comprises: brown coal device for improving quality, cyclone separator, desulfurizer, first air-introduced machine, deduster, chimney, denitrification apparatus, boiler, electric dust collector, second air-introduced machine, the 3rd air-introduced machine and the 4th air-introduced machine; Wherein: the exhanst gas outlet of boiler links to each other with denitrification apparatus, the 4th air-introduced machine, electric dust collector, the 3rd air-introduced machine and brown coal device for improving quality gas approach successively; The solid phase outlet of brown coal device for improving quality links to each other with the brown coal import of boiler; The gaseous phase outlet of brown coal device for improving quality links to each other with chimney with cyclone separator, first air-introduced machine, deduster, second air-introduced machine, desulfurizer successively; From cyclone separator and deduster separate less than the enrichment of 2mm the brown coal of sulphur and mercury be collected in together and pack, be used for water treatment or security landfill;
A kind of gas cleaning of the utility model and the compound system of brown coal upgrading, wherein: said brown coal device for improving quality is recirculating fluidized bed, fluid bed, multistage shaking table or boiling type device;
A kind of gas cleaning of the utility model and the compound system of brown coal upgrading, wherein: said deduster is sack cleaner, electric cleaner or electricity bag integration dust-removal device.
The gas cleaning of the utility model is compared with existing flue gas purification system with the compound system of brown coal upgrading; Its advantage is: the utility model unites two into one gas cleaning and brown coal upgrading, and the utility model comes dry brown coal in the waste heat amount of effectively utilizing boiler exhaust gas, when significantly improving its calorific value; Make full use of pore structure and abundant surface functional group adsorption cleaning flue gas that brown coal itself are had; Improve the efficiency of combustion of brown coal, reducing equipment investment, optimizing operational efficiency; In the time of energy savings, reduced disposal of pollutants.Can be reduced to 10-25% with the moisture of brown coal by original 30-40%, significantly improve the calorific value of brown coal, improve efficiency of combustion, reduce the investment of abrasive dust and boiler; Because brown coal itself possess characterization of adsorption, it has adsorbed the sulphur and the mercury of flue gas, and is enriched in the fine powder less than 2mm, is used for sewage disposal or security landfill.Make flue gas reach the effect of desulfurization and demercuration, thereby reduced investment of devices, optimized operational efficiency, practiced thrift the energy, reduced the heat discharging, reduced consumption, increased efficient through behind the brown coal.
