Description
Technical field
The utility model relates to a kind of chain-grate boiler, especially a kind of single drum triple channel chain-grate boiler that is used for burning domestic garbage.
Background technology
The world today, a large amount of rubbish has become long-standing pollution sources in the city.Along with being on the increase and the raising day by day of living standards of the people of expanding economy, population, the generation of municipal refuse also day by day increases.The Application and Development of greatly developing city garbage burning Study on Technology and equipment is imperative.
The boiler of burning away the refuse at present mainly contains two kinds of CFBB and chain-grate boilers.Fluidized combustion mainly relies on the effect of the high heat capacity of high temperature fluidized bed material in the burner hearth, strong blending and heat transfer, the rubbish of sending into burner hearth is rapidly heated catches fire, and forms the even burning in the whole bed.This structural limitations the after-flame of fuel volatile matter gas, the control of pollutant is had certain effect.But its shortcoming is also very outstanding: structure and complicated operation, and the flying dust ratio is higher, and the ash amount is bigger.The adaptability that the rubbish composition is changed is not strong, to heating surface and water the corrosion of material feeding and serious wear etc.And great majority need be mixed when operation and burn a certain proportion of coal, increase operating cost.The chain garbage burning boiler mainly enters boiler with rubbish by charging gear, and in the preheating after-combustion.By the motion of fire grate segment, rubbish moves on fire grate continuously and equably, helps quickening the drying of rubbish and catching fire, and produces the good effect of burning.It is reliable, and disposal of refuse speed is fast, and treating capacity is big, effectively reduces advantages such as pollutant emission.But in the shortcoming aspect the burning be: when boiler operatiopn, owing to be furnished with more evaporating heating surface in the burner hearth, fractional cold is bigger, the incineration firing that causes entering burner hearth is not thorough, efficiency of combustion is not high, and the harmful substance that incineration firing is produced can not thoroughly be decomposed, and causes atmosphere pollution; Secondly, because burner hearth internal combustion operating mode is more violent, temperature is higher, causes heating surface and waters the high temperature corrosion and the serious wear of material feeding, influences the economy of boiler operatiopn.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of single drum triple channel of economy chain-grate boiler that improves the garbage fired boiler operation is provided.
The technical scheme that provides according to the utility model, a kind of single drum triple channel chain-grate boiler comprises boiler and is installed in rubbish fire grate, economizer, air preheater, the slag remover of boiler below, feature is: the furnace chamber of described boiler is separated into first passage, second channel and third channel by furnace wall, described refuse furnace ranking is in the below of first passage, the front end of described rubbish fire grate is provided with the garbage feeding mouth, and the rear end of rubbish fire grate is provided with the waste residue slag-drip opening; Above described third channel, be provided with exhaust pass, the convection heating surface that below exhaust pass, sets gradually air preheater, economizer and make by tube bank, bottom at described third channel is provided with slag remover, the top of described garbage feeding mouth is installed into funnel, and ash dropping hopper is installed under described convection heating surface.
On the both sides furnace wall of first passage above the described rubbish fire grate, face arch and rear arch are set respectively.
Furnace wall top between described first passage and the second channel is provided with the passage that flue gas passes through.
Furnace wall below between described second channel and the third channel is provided with the passage that flue gas passes through.
Drum is installed at described boiler top, utilizes fairlead and down-comer to be connected between described upper drum and the convection heating surface.
The utility model is simple in structure, reliable, garbage disposal speed is fast, and rubbish adaptability is strong, and floor space is little, easy for installation, three-channel structural design and heating surface is arranged in structure in the third channel (back-end ductwork) improves incineration firing efficient, reduces the generation and the discharging of harmful substance, while can be reduced boiler heating surface effectively and be watered the corrosion and the wearing and tearing of material feeding, improves the economy of garbage fired boiler operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in the figure: single drum triple channel chain-grate boiler comprises rubbish fire grate 1, first passage 2, garbage feeding mouth 3, waste residue slag-drip opening 4, second channel 5, ash dropping hopper 6, upper drum 7, convection heating surface 8, rear arch 9, fairlead 10, third channel 11, economizer 12, air preheater 13, exhaust pass 14, loading hopper 15, slag remover 16, face arch 17, down-comer 18 etc.
The utility model comprises boiler body and is installed in the rubbish fire grate 1 of boiler below, the body of described boiler is separated into first passage 2, second channel 5 and third channel 11 by furnace wall, described rubbish fire grate 1 is positioned at the below of first passage 2, the front end of described rubbish fire grate 1 is provided with garbage feeding mouth 3, and the rear end of rubbish fire grate 1 is provided with waste residue slag-drip opening 4; Above described third channel 11, be provided with exhaust pass 14, below exhaust pass 14, set gradually air preheater 13, economizer 12 and, ash dropping hopper 6 is installed under convection heating surface 8 by the convection heating surface 8 that tube bank is made; Above garbage feeding mouth 3, be installed into funnel 15; Be provided with slag remover 16 in the bottom of third channel 11.Face arch 17 and rear arch 9 are set respectively on the both sides furnace wall of first passage 2 above the rubbish fire grate 1; Above the furnace wall between first passage 2 and the second channel 5, be provided with the passage that can allow flue gas to pass through; Below the furnace wall between second channel 5 and the third channel 11, be provided with the passage that can allow flue gas to pass through; Install drum 7 at the boiler top, utilize fairlead 10 and down-comer 18 to be connected between described upper drum 7 and the convection heating surface 8.
