Technical field
The utility model relates to a kind of incinerator, particularly relates to a kind of New-type refuse vehicle and biomass fuel incinerator.
Background technology
Being applied to rubbish and biomass fuel at present burns and to mainly contain fire grate fixed bed, circular flow flower beds and three kinds of combustion furnaces of brickkiln and burn, the burning of fire grate fixed bed is because of the fire grate structure complexity, the manufacturing cost and use cost height, the fire grate heating surface is big, burn out and need blowing out to change fire grate easily, because fire grate need dispel the heat and make, the excessive waste heat boiler thermal efficiency of air distribution is low, often need additional fuel oil combustion-supporting because furnace temperature is low, not environmental protection is also uneconomical.The flame-out easily and coking of circular flow flower beds burning, thereby the siege temperature must be controlled at 800 ℃-900 ℃, the interval generation that is difficult to control dioxin nuisance of this furnace temperature, effectively the furnace temperature of control dioxin nuisance generation is because of being higher than 1000 ℃, flue gas should stop more than 2 seconds, had limited the application of circular flow flower beds burning bed mode owing to this reason.There is the body of heater place of being rotationally connected sealing difficulty in the rotary kiln burning, and the waste heat boiler thermal efficiency is very low, the perishable maintenance trouble of rotary kiln liner, and it is insufficient to burn, and problems such as transmission complexity are so rotary kiln is in fact seldom used.
Summary of the invention
The purpose of this utility model just provides a kind of New-type refuse vehicle and biomass fuel incinerator, the furnace temperature height, can effectively control the generation of dioxin nuisance, can reduce the dust stratification of incinerator and waste heat boiler, improve the thermal efficiency of furnace temperature and waste heat boiler, structure is simpler, and durable reliable, few fault, easy to maintenance.
For achieving the above object, the utility model adopts following technical scheme:
A kind of New-type refuse vehicle and biomass fuel incinerator, comprise: body of heater, the combustion chamber, dog-house, slag bucket, slag-drip opening, be provided with the primary zone in the described body of heater, secondary combustion chamber, waste heat boiler, dog-house to inclined-plane downward between the slag bucket is a burning bed, be provided with the primary zone in the cavity on burning bed top, and be communicated with dog-house, secondary combustion chamber is arranged on the middle part of the body of heater inner chamber on top, primary zone, primary zone's arch is set between primary zone and the secondary combustion chamber, the anterior face sealing in its arch front end and furnace wall, the rear end is communicated with secondary combustion chamber, and cover the top and the two sides of primary zone, the secondary combustion chamber arch is set between the waste heat boiler of secondary combustion chamber and upper of furnace body, its arch rear end and the sealing of furnace wall, body of heater rear portion face, the waste heat channel connection of front end and waste heat boiler, it is the primary zone, secondary combustion chamber and waste heat boiler form " Z " or fall " Z " shape passage, inclined-plane burning bed bottom surfaces is provided with the jet pin-lift arrangement of many groups, dog-house connects automatic feeder, and the slag-drip opening place of slag bucket is provided with the screw rod slag extractor.
Described primary zone is provided with the secondary hot-air nozzle that is communicated with inner chamber with the interchannel body of heater of secondary combustion chamber.
The described body of heater port of export is provided with air preheater, and air preheater is communicated with air inlet pipe under secondary hot-air nozzle and the inclined-plane burning bed by air blast and control valve with pipeline.
Described jet pin-lift arrangement is communicated with the inclined-plane burning bed by straight tube, one side on pipe top connects air inlet pipe respectively, one end of push rod penetrates in the straight tube, the other end connects cylinder piston rod, can move up and down and indoor comburant and the slag of jack-up primary combustion along pore at the effect lower push rod of cylinder.
The utility model is owing to adopt secondary combustion chamber to cover the design of top, primary zone and side, make the incinerator structure firmer rationally, burning gallery employing " Z " or " Z " shape structure of falling not only help effective utilization of heat energy, burning gallery has simultaneously also extended, make flue gas in the combustion chamber, stop more than 3 seconds, secondary combustion chamber continues to heat to the primary zone by primary zone's arch wall and can obviously improve the kiln temperature, quicken the burning of combustible, decompose and gasification, owing in body of heater, be provided with the secondary hot-air nozzle that is communicated with inner chamber, make combustion-supporting hot-air carry out combustion with meagre oxygen, can make chamber temperature reach 1000 ℃-1200 ℃, can effectively control the generation of dioxin nuisance; Because burning bed is arranged with the jet pin-lift arrangement of many groups, spray combustion air at a high speed by air jet pipe, can make combustible become semi-fluid combustion decomposition and gasification to burnout up to combustible, push rod ejects according to the order of sequence, can move down combustible and the loose past inclined-plane of lime-ash or coking material top, becoming lime-ash up to after-flame drops in the slag bucket, jet pin-lift arrangement is very little in the contact area of combustion chamber, air jet pipe is jet not only can to cool off push rod and nozzle, can also reduce under the burning bed and blow into quantity of hot air, effectively reduce the flue gas flying dust, reduce the dust stratification of incinerator and waste heat boiler, thereby improved the thermal efficiency of furnace temperature and waste heat boiler; Its structure is simpler more and more durable reliable than fire grate fixed bed combustion system structure, and few fault is easy to maintenance.
