Description
Technical field
The utility model relates to soot blower technical field, especially relates to a kind of shock-wave ash-clearing rifle.
Background technology
During boiler operatiopn, water or steam constantly and flue gas carry out heat exchange.After flue-gas temperature reduces, when temperature will cause the deposition of ash lower than during fusion point of ash, dust stratification can be divided into high-temperature deposition and low temperature dust stratification two class.High-temperature deposition mainly produces adhesiveness dust stratification and caking property dust stratification.Wherein adhesiveness dust stratification is mainly because the low-melting-point metal element contained in high-temperature flue gas produces coagulation when cigarette temperature drop is low, forms closure ash ring.Caking property dust stratification is when changing to transition temperature district in high-temperature region, because flue gas carries out transversal flow to pipe, forms molten dust stratification cause smoke pipeline blocked in pipe front.Low temperature dust stratification mainly occurs in the afterbody of boiler and the temperature tube wall lower than acid dew point.Ash content that is large due to afterbody low-temperature space area, burning increases, and adds that the temperature of the air inlet reason such as incomplete combustion, boiler heating surface layout imbalance, slag-blowing equipmemt imperfection caused on the low side causes the formation of dust stratification; The mainly loose type dust stratification that low temperature dust stratification is formed.
In addition, in some industrial furnace, flue, conveyance conduit, various cooling tower, reactor inside, after long-play, because of dust accumulation, material sedimentation, its inner formation dust layer or material dirt layer.Affect the normal operation of equipment, time serious, equipment need shut down cleaning.To this kind equipment, there is no special ash removing equipment at present, main by artificial deashing.Labour intensity is large, work under bad environment.And during deashing, equipment need shut down operation.
