Technical field
The invention belongs to field of combustion equipment during accumulation of heat, and in particular to a kind of block-resistant type rotary wings heat accumulating burner.
Background technology
China is characterized the air combined pollution of pollutant with PM2.5 and O3, and the situation is tense, VOC
(VOCs, Volatile Organic Compounds) is the important as precursors thing for causing O3 to pollute, and also has weight to PM2.5 generations
Influence.When VOCs concentration exceedes finite concentration in atmosphere, human body has headache and weak neurotoxicity, the improvement to VOCs
Become country's great environmental problem urgently to be resolved hurrily, thus pernicious gas processing it is up to standard after could discharge, typically make
With regenerative burner device (RTO, regenerative thermaloxidizer system), it can enter to pernicious gas
The processing of row pyrolytic.Heat accumulating type oxidation furnaces develop into three Room from two Room, occur in that within this several years that one kind efficiently, is impacted smaller again
Rotary RTO, profile also develops into circle by box-type, more saves place.But there is changeover valve in this rotary RTO
Dynamic sealing problem, because changeover valve is using friction dish structure, stator and too big RTO points of the easily leakage influence in rotor seal gap
Solve efficiency, stator and the too small easy abrasion in rotor seal gap, and be difficult to repair and change, also deposit be difficult to processing high viscosity, it is easy
The pernicious gas of fouling；Surface is blocked or be deposited in the supply heat storage of regenerative apparatus by grease or dirt, it is impossible to effectively enters
Row heat exchange and cause temperature drop.The supply heat storage of regenerative apparatus is contaminated, and increases pressure, influences the gas of body interior
Stream, thus causing the operation cost of device increases even failure.
The content of the invention
It is anti-blocking it is an object of the invention to provide a kind of block-resistant type rotary wings regenerative oxidation device in order to solve the above problems
