Description
Technical field
Utility model belongs to Industrial Boiler Technology field, and the recirculating fluidized bed of deposition is difficult more particularly, to a kind of heating surface
Boiler.
Background technology
Existing sludge, generally burns to be handled using boiler.But, find after long-term use, due to sludge
Interior containing substantial amounts of chlorine element, when burn reaction, chlorine element can react with lime stone, produce fusing point and be less than furnace chamber
The calcium chloride of temperature, so as to cause serious deposition in furnace chamber inwall, causes boiler infrequently blowing out must not be cleared up, greatly
The influence operating efficiency of degree；And then, deposition problems are had become using urgent during fluidized bed incinerator method disposing sludge
Need the bottleneck problem solved.
Utility model content
The utility model in order to overcome the deficiencies in the prior art there is provided it is a kind of long-term using being also not susceptible to precipitation, need not
The heating surface frequently cleared up is difficult the CFBB of deposition.
To achieve these goals, the utility model uses following technical scheme：A kind of heating surface is difficult the circulation of deposition
Fluidized-bed combustion boiler, including sludge-tank, dechlorination unit and the boiler being sequentially connected, the sludge-tank are located at the top of the dechlorination unit
Position；The dechlorination unit includes dechlorination chamber, the agitator located at dechlorination chamber bottom, antichlor tank, connection dechlorination chamber and dechlorination
The feed tube of agent tank, it is communicated in the cloth water cavity of water inlet pipe and some water-distribution nozzles on the cloth water cavity.The utility model exists
Dechlorination apparatus is set between boiler and sludge-tank, and sludge first passes through dechlorination chamber and carry out dechlorination processing, make between boiler is entered to
Obtain sludge to react with the antichlor in dechlorination chamber, form sodium chloride；And then when entering progress burning reaction in boiler, chlorine
Change sodium will not be reacted with lime stone, the relatively low calcium chloride of fusing point just can not be formed in boiler, enter without boiler by
Deposition is produced on hot face；Water distribution is carried out by shower nozzle, water distribution effect is good, while coordinating agitator so that sludge and antichlor
Mixing is more abundant, and dechlorination effect is more preferable.
It is preferred that, a sludge dewatering room is provided between the dechlorination chamber and boiler；Due to the penetrating of antichlor so that sludge
Interior water content is higher, after dewatering station carries out dewater treatment, effectively reduces the water content of sludge, is burned entering boiler
When, the duration of burning can be shortened, the use of fuel, more energy-conserving and environment-protective is saved.
Further, there is a sewage sludge feed device between the sludge dewatering room and boiler.
Further, gap distribution has multiple stomatas on the blade of the agitator, and the stomata is used to open provided with one
The upset blade of the stomata is closed, the agitator one end connects an air intake；Stomata can be sprayed during agitator is stirred
Gas, and then sludge is broken up so that sludge mixes more abundant with antichlor, and dechlorination effect is preferable；Blade is overturn in gas
Hole is not ventilated, and stomata can be closed, and effectively prevents that sludge from entering blowhole.
Preferably, the upset blade is provided with a stopper protrusion, the blade is provided with to match with the stopper protrusion
The recess of conjunction；When upset blade is closed to stomata, convex portion can be caught in recess, and then blade can be achieved for stomata
Complete closure, can prevent that blade from falling into stomata again, closure effect is good, and sludge will not be entered in stomata.
Or preferably, the closing direction of the upset blade is opposite with the direction of rotation of the agitator；And then in stirring
In the rotary course of device, upset blade all the time can by sludge active force, keep the state closed to stomata；Work as stomata
In use, gas can wash blade open naturally, sludge is broken up.
It is preferred that, the sewage sludge feed device includes being located at the charging aperture of the position of boiler 3/4ths, is connected to this
The feed pipe of charging aperture and the screw(-type) feeder in feed pipe；The other end of the feed pipe connects the sludge dewatering room；
The position of charging aperture is higher, and sludge is when falling with longer stroke, and then moisture in sludge can carry out natural drying, just
In burning, the use of incendiary material, more energy-conserving and environment-protective can be reduced.
In summary, the utility model sets dechlorination apparatus between boiler and sludge-tank so that sludge is before burning
Chlorine element in leading dechlorination processing, sludge can not be reacted with lime stone, and deposition is not likely to produce in boiler furnace chamber.
