Description
Technical field
The present invention relates to a kind of rubbish furnace structure, present invention relates especially to a kind of saturated fluidized bed rubbish with afterburning chamber
Furnace structure.
Background technology
With Environmental Protection in China requirement increasingly raising, for avoid environmental pollution and consider resource regeneration the problems such as, rubbish
No longer arbitrarily filled, but reused by some means, one of which is that rubbish is entered using boiler
Row is burned and produces heat energy.
As a rule, it is divided into two kinds as the boiler of fuel using rubbish：Fire grate garbage incinerator and recirculating fluidized bed rubbish
Rubbish incinerator.But without punishing using which kind of type of furnace, there are several hang-ups in garbage burning boiler all the time：How secondary pollution is solved
Problem and how to solve High Temperature Corrosion of boiler heating surface etc..
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided one kind can simultaneously solve fluid bed rubbish
Boiler secondary pollution and the saturated fluidized bed rubbish furnace structure with afterburning chamber of the hang-up of high temperature corrosion two.
According to the technical scheme that the present invention is provided, the saturated fluidized bed rubbish furnace structure with afterburning chamber, including sinciput
Plate and rear top board, are hung with burner hearth on front top plate, and afterburning chamber is hung with rear top board, and afterburning chamber is by afterburning chamber epimere and benefit
Combustion room hypomere is constituted, and afterburning chamber epimere is membrane wall structure with the wall body of afterburning chamber hypomere, and medium is carbonated drink in membrane wall pipe
Mixture, is provided with afterburning burner at the top of afterburning chamber epimere, garbage feeding mouthful is provided with burner hearth, in the bottom of burner hearth
Water cooled wind chamber and igniter are installed, cyclone separator, the outlet of burner hearth and entering for cyclone separator are provided with the rear of burner hearth
Mouthful connect, refeed line be installed in the bottom of cyclone separator, bed addition mouth is installed on refeed line, refeed line it is another
Terminate at behind the bottom of burner hearth on wall, afterbody passage is provided with the rear of cyclone separator, province's coal is installed in afterbody passage
Device and evaporation convection tube bank, economizer are located at the top of evaporation convection tube bank, afterbody passage and benefit below evaporation convection tube bank
It is connected by connecting smoke pipe between combustion room hypomere.
SNCR spouts are installed in the outlet of the burner hearth.
Sealing device is installed on the afterburning burner.
The setting that the present invention passes through the reasonable Arrangement to saturated fluidized bed heating surface, especially afterburning chamber, both effectively suppressed
The generation of incineration firing product Zhong bioxin, reduces the flue-gas temperature into evaporation convection tube bank again, protects evaporation convection
Tube bank pipe is not corroded by high-temperature flue gas, while solving the secondary pollution of fluid bed garbage fired boiler and the hang-up of high temperature corrosion two.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is the structural representation of afterburning chamber epimere in the present invention.
Specific embodiment
With reference to specific embodiment, the invention will be further described.
The saturated fluidized bed rubbish furnace structure with afterburning chamber, including front top plate 6 and rear top board 7, hang on front top plate 6
There is burner hearth 1, afterburning chamber is hung with rear top board 7, afterburning chamber is made up of afterburning chamber epimere 11 with afterburning chamber hypomere 12, afterburning chamber
Epimere 11 is membrane wall structure with the wall body of afterburning chamber hypomere 12, and medium is steam water interface in membrane wall pipe, in afterburning chamber
The top of epimere 11 is provided with afterburning burner 17, and garbage feeding mouthful 4 is provided with burner hearth 1, and water is provided with the bottom of burner hearth 1
Cold air chamber 2 and igniter 3, cyclone separator 9, the outlet of burner hearth 1 and the import of cyclone separator 9 are provided with the rear of burner hearth 1
Connect, refeed line 10 is installed in the bottom of cyclone separator 9, bed addition mouth 15, refeed line are installed on refeed line 10
Behind 10 another bottom for terminating at burner hearth 1 on wall, afterbody passage 16 is provided with the rear of cyclone separator 9, in afterbody passage
Economizer 14 and evaporation convection tube bank 13 are installed, economizer 14 is located at the top of evaporation convection tube bank 13, evaporation convection in 16
It is connected by connecting smoke pipe 20 between the afterbody passage 16 and afterburning chamber hypomere 12 of the lower section of tube bank 13.
SNCR spouts 8 are installed in the outlet of the burner hearth 1.
Sealing device 18 is installed on the afterburning burner 17.
Afterburning burner 17 is using calorific value clean fuels higher, the steaming in afterbody passage 16 such as natural gas, 0# light diesel fuels
Hair convection bank 13 and economizer 14 are in the form of coarse pitch, in-line arrangement.
During concrete application, flue gas from after the outlet out of burner hearth 1, by after the separation of cyclone separator 9 enter afterburning chamber
The top of epimere 11, the flue gas after the afterburning burner 17 pairs at the top of afterburning chamber epimere 11 is separated carries out afterburning, has reached
Effect is pyrolyzed the temperature of bioxin, and then afterburning chamber hypomere 12 is lowered the temperature to the high-temperature flue gas after afterburning again, is so made full use of
Afterburning chamber, had both effectively inhibited the generation of bioxin in incineration firing product, reduced again into evaporation convection tube bank 13
Flue-gas temperature, protects evaporation convection to restrain pipe 13 and is not corroded by high-temperature flue gas, while solving the secondary dirt of fluid bed garbage fired boiler
Dye and the hang-up of high temperature corrosion two.
