Detailed description of the invention
Below, sulfur removal technology and the device of setting up stable circulation fluid bed fast of the present invention is described in detail with reference to accompanying drawing.
In circulating fluidized bed desulfurization technique, three subject matters the most easily occurred comprise collapse bed, spray gun blocking and reaction tower of fluid bed and glue the even stifled tower of wall, cause the reason of above-mentioned phenomenon as follows:
A, fluid bed collapse bed: cause because the gas-particle two-phase in reaction tower is seriously out of control, and in tower, air flow method is uneven, and in tower, solid matter is too many, cannot circulate and destroy cyclic balance.
B, reaction tower glue the even stifled tower of wall: because the slurries in reaction tower seriously cause in tower wall bonding, the liquid phase substance in tower is too many, enters the air-flow shortage of heat in tower or can not evaporate the moisture entered completely.
C, spray gun block: cause because the slurries sprayed in reaction tower comprise the grit that cannot digest.
By analysis, think that the generation of above-mentioned phenomenon is mainly because reaction tower glues wall, has a strong impact on air flow method in tower, make solid matter in tower cannot circulate and destroy cyclic balance, thus cause fluid bed to collapse bed or the fluid bed of stable operation can not be set up for a long time.Therefore, the wall sticking phenomenon solving reaction tower is crucial, and stifled tower is the serious performance of sticky wall.Inventor is by analyzing the tower wall hydrodynamics of micro, if find that liquid-solid two-phase particle all likely causes wall sticking phenomenon in the contact of tower wall, and sticky wall degree is directly proportional to liquid phase, is inversely proportional to solid phase.Given this, need between tower wall and liquid-solid two-phase particle, add a protective layer, to avoid or to stop liquid-solid two-phase particle in the contact of tower wall, thus prevent collapse bed, spray gun blocking and reaction tower of fluid bed from gluing the generation of the phenomenons such as the even stifled tower of wall.
Set up the sulfur removal technology of stable circulation fluid bed according to an exemplary embodiment of the present invention fast, the solid particle in the flue gas after desulfurization of discharging from fluid bed reacting tower outlet is separated, and the solid particle after being separated is returned the bottom being sprayed onto fluid bed reacting tower.Again the solid particle sprayed into can stick to Ta Bishang, forms a protective layer, thus stops liquid-solid two-phase particle in the raw material newly added to stick to Ta Bishang.Further, the solid particle again sprayed into can increase calcium reaction of Salmon-Saxl chance, reduces calcium sulfur ratio, regulates the moisture of recirculating fluidized bed, reaches to solve collapse bed, spray gun blocking, reaction tower of fluid bed and glue the object of the problems such as wall.
