Detailed description of the invention
The zero-emission no chimney coal-burning boiler system that the utility model proposes, its structure as shown in Figure 1, comprises boiler 4, deduster 5, high temperature draught fan 6, waste-heat recovery device 7, desulfurization fills and 8 to put, catch CO
2device 9, denitrification apparatus 10, oxygenerator 11, air blast 12 and slurry pump 13.The import of deduster 5 is connected with the exhaust opening of boiler 4, and the gas vent of deduster 5 is connected with the air inlet of boiler 4 with described air blast 12 by described high temperature draught fan 6.The ashes outlet of boiler 4 and the solid outlet of deduster 5 are discharged by described slurry pump 13.Waste-heat recovery device 7, desulfurizer 8, seizure CO
2device 9, denitrification apparatus 10 and oxygenerator 11 are connected with the ring-shaped flue between the gas vent of deduster 5 and the air inlet of boiler 4 respectively.
Coal dust supply system and slag is also provided with, thin grey exhaust system, raw coal funnel 1 as shown in Figure 1, coal pulverizer 2 and coal dust 3 in the Inner eycle steam generator system that the utility model proposes.
The zero-emission no chimney coal-burning boiler system that the utility model proposes, by original from smoke stack emission to air in flue gas, introducing is placed in the flue on ground, the diameter of flue and length look flue gas number and process requirement determine, flue gas carries out dedusting in flue, waste heat recovery, desulfurization, denitration, carbon dioxide removal.Then, supplemental oxygen in treated high-temperature flue gas, burning consumes how many how much supplementing.The power that flue gas runs in flue, is provided by the high temperature draught fan matched with boiler and air blast.
The operation principle of the zero-emission no chimney coal-burning boiler system that the utility model proposes is as follows:
As shown in Figure 1, raw coal forms coal dust 3 by coal bunker 1 through coal pulverizer 2 and sends boiler 4 to and burn, the lime-ash after burning directly or mix by slurry pump 13 with ash flushing water through deduster 5) deliver to the further processing and utilization of grey factory.The flue gas produced in combustion process carries out waste heat recovery 6 after deduster 5 dedusting, and the waste heat of recovery can also be able to be used for freezing as the thermal source of city central heating.Afterwards, under the effect of high temperature draught fan 7, the boiler smoke through dust removal process and cooling process needs through desulfurizer 8 desulfurization; Catch CO
2device 9 reclaims carbon dioxide, denitrification apparatus 10 denitration, and the boiler smoke crossed through above-mentioned 8,9 and 10 3 step process substantially purifies, and the processing procedure of these three steps can produce many byproducts, as carbon dioxide, and utilization of all can rising in value.The high-temperature oxygen-enriched gas supplementing oxygen through oxygenerator 11 supplemental oxygen, then is sent into inlet air of boiler mouth by air blast and the passage arranged specially by boiler smoke that purified treatment is crossed again, so completes the circulation of combustion air in combustion process.In above process, except the oxygen consumed by oxygenerator 11 aftercombustion in right amount, do not have outside air to participate in boiler combustion process directly, also not to any flue gas of airborne release, achieve the zero-emission of coal-fired boiler combustion process.
The zero-emission no chimney coal-burning boiler system that the utility model proposes, again sends into inlet air of boiler mouth by air blast after supplementing pure oxygen, eliminate the chimney of conventional boiler to the flue gas produced in combustion process.Combustion process is participated in, also not to airborne release flue gas without outside air in boiler running process.Achieve the zero-emission of coal-burning boiler.
