Description

A kind of folding intelligence deashing device

Technical field

Technical field of dust removal equipment is the utility model is related to, especially a kind of folding intelligence deashing device.

Background technology

In combustion furnace, kiln among present enterprise generally set a flue, by caused flue gas in burning with it is small Particle dust is transported among cleaner.But in use, there is part flue dust to be constantly adhered to the interior of flue On wall, after long-time use, if smoke moisture is big and ash can the fouling on wall panel when cigarette temperature is less than acid dew point.These foulings If accumulation will cause flue blockage throughout the year, the discharge of flue gas and the use of combustion furnace are influenceed, to prevent dust in flue gas Deposited in flue, the flue gas flow rate for typically requiring pipeline is 10~15 meter per seconds, because cause specific must reduce flue gas flow rate extremely 7 meter per seconds or so, inevitably dust stratification is caused in flue, and if smoke moisture is big and cigarette temperature is less than grey meeting during acid dew point The fouling on wall panel.Its flue gas operating mode is as follows：Flue-gas temperature：125℃；Dust content：30g/Nm3.Dust main component It is as follows：Total moisture：21%；As-received ash content：14.37%；As-received oxygen：9.4%, full sulphur：0.8%；Silica： 44.67%；Calcium oxide：11.36%；Alundum (Al2O3)：19.27%；Di-iron trioxide：7.23%.
