Description
Technical field
The utility model relates to energy environment protection technical field, refers to a kind of granule activated coke multistage suspension formula flue gas desulfur device especially.
Background technology
Activated coke desulfurization technology is the flue gases purification that a kind of physical absorption-chemisorbed combines.Activated coke after absorption, through regeneration, can obtain sulfuric acid, liquid SO
2or the byproduct such as elemental sulfur, realize the recovery of Sulphur ressource.
Activated coke desulfurization technology because of efficient, water saving, can the advantages such as Sulphur ressource be reclaimed, become a kind of flue gas pollutant control technology being particularly suitable for the few water area of the rich coal of China.Activated coke desulfurization system mainly comprises flue gas desulfur device, regenerating unit, device for transporting objects and by-product production device.Flue gas desulfur device is the important component part of activated coke desulfurization system, determines desulfuration efficiency and the availability of desulphurization system.
At present, the principal mode that activated coke desulfurization device adopts has fixed bed, moving bed and fluid bed three kinds of forms, wherein, applies most often moving bed desulfurizer at present.
In fixed bed desulfurizer, active carbon is fixed in device, and the flue gas entered adsorbs in fixed bed, and after charcoal absorption is saturated, beginning switching device carries out the regeneration of adsorbent; Moving bed desulfurizer can realize continuous operation, and active carbon generally moves from top to bottom by gravity, and flue gas is horizontal or flow from bottom to top, with active carbon cross-flow or counter current contacting; Adsorption zone in fluidized bed desulfurizing device, flue gas and active carbon layer counter current contacting, reach the upper end storage tank that the saturated active carbon of absorption delivers to fluid bed, and be conveyed to renewing zone, the active carbon after regeneration enters adsorption zone downwards again.Fixed bed desulfurizer can run into the large and regeneration of air flow method inequality, pressure drop and switch the problems such as frequent when the exhaust gas volumn processed is large, and usually can only accomplish semicontinuous operation; Moving bed desulfurizer continuously-running, but there is the problems such as activated coke loss is larger; Then there is bad adaptability in fluidized bed desulfurizing device, to problems such as operation control overflow are high.
The activated coke that usual active coke desulphurizing device adopts is that Constitutive active is burnt, and conventional diameter is about 5 ~ 9mm, and length is about 10 ~ 20mm.Constitutive active Jiao obtains by being carried out by feed coal bonding, after shaping, carbonization and activation process, and price is relatively high.Meanwhile, Constitutive active is burnt also exists the larger problem of wearing and tearing in running.Therefore, this inevitably causes the problems such as the operating cost of desulfurizer is higher.Granule activated coke, can by the feed coal direct carbonization of certain particle size activation preparation activated coke in the fabrication process without the need to adopting bonding, moulding process, and manufacturing cost is compared can reduce by more than 80% with Constitutive active Jiao.Therefore, if active coke desulphurizing device adopts granule activated coke to substitute shaping activated coke as absorbent, greatly operating cost can be reduced.
At present, although granule activated coke has larger price advantage, when active coke desulphurizing adopts moving-burden bed reactor, reactor resistance will greatly increase for activated coke, and also may cause moving-burden bed reactor cannot continuous and steady operation.
Adopt moving-burden bed reactor to adopt granule activated coke resistance large and may continuous and steady operation to solve, and adopt the problem that the burnt price of Constitutive active is higher, need to research and develop novel granule activated coke desulfurization device.
