Abstract
The present invention relates to a compound combustion-incineration furnace for garbage coal powder, which is characterized in that a garbage grate combustion mode is combined with a coal powder combustion mode; a space above a garbage grate incinerating layer is used as a coal powder combustion space, and a furnace wall at the side surface of the coal powder combustion space is provided with one or a plurality of coal powder combustor with a low NOx rotational flow. The incinerating furnace has the advantages of stable heat source, high combustion efficiency, no need of adding oil to support combustion, and little pollutant discharge.
Description
Technical field
The present invention relates to the compound incinerator of a kind of rubbish coal dust, belong to environmental protection equipment.
Background of invention
Garbage disposal at present has three kinds of modes: sanitary landfills, compost treatment and burning disposal.Wherein burning disposal is the widely used efficient ways of industrially developed country, and it can realize the minimizing of treatment of urban garbage, innoxious and resource to greatest extent.Incinerator is commonly used mechanical grate incinerator, fluidized bed incinerator, rotary kiln incinerator and heat decomposition incinerator etc., the development of stoker fired grate incinerator early, form is more, and its common characteristic is to adopt the grate firing mode, organizes burning with the force ventilation form on stoker fired grate.Because the municipal refuse calorific value is lower, combustible content is few, add all multifactor influences such as season, rubbish is instability when burning, and it is combustion-supporting often to add auxiliary fuel, has influenced the economic benefit and the availability of incinerator, again because the restriction of the fire grate thermic load of incinerator, the temperature of incinerator is limited in 800-900 ℃, and it is not thorough to cause in the waste incineration process harmful components such as dioxin to be decomposed, and influences rubbish after-flame effect simultaneously yet.
Summary of the invention
Purpose of the present invention is the shortcoming and deficiency in order to overcome above-mentioned prior art just, and the rubbish coal dust compound combustion incinerator that provides a kind of rubbish fire grate combustion system to combine with the coal dust firing mode, thereby can make rubbish smooth combustion, drying garbage, burning, burn-up efficiency have been improved, reduced the discharging of dioxin, made garbage disposal more economical effectively.
The objective of the invention is to realize by following technical proposal:
Rubbish coal dust compound combustion incinerator, it comprises by feed hopper 1, dispenser 11, fire grate 2, deslagging 5, burner 3, reaches the waste-heat oven of being made up of drum 6, superheater 9, air preheater 7, economizer 84, it is characterized in that the waste incineration layer superjacent air space that dryer section 2-1, burning zone 2-2 at fire grate and after-flame section 2-3 form is coal dust firing space 12, one or more low NO are installed on the furnace body wall of side, coal dust firing space
xVortex burner 3, described low NO
xVortex burner 3 is made up of airduct 3-2 and secondary air channel 3-1.
Owing to take technique scheme to make the technology of the present invention compared with the prior art have following advantage and effect:
(a) adopt low NO
xVortex burner combines with rubbish fire grate combustion system and has very strong steady burning ability, ejection produces stable thermal-flame to coal air mixture through burner, help rubbish drying, catch fire, thermal-flame also helps the dioxin decomposition simultaneously, reduced dioxin emission, rubbish and coal dust be in the incinerator internal combustion, and can support mutually, need not refuel combustion-supporting;
(b) simple in structure, easy to operate, easy to utilize.
Description of drawings
Fig. 1 is an incinerator structural representation of the present invention
The specific embodiment
Rubbish coal dust compound combustion incinerator, by shown in Figure 1, it comprises by feed hopper 1, dispenser 11, fire grate 2, slag-drip opening 5, burner 3, reaches the waste-heat oven of being made up of drum 6, air preheater 7, economizer 84, the waste incineration layer superjacent air space of forming at dryer section 2-1, burning zone 2-2 and the after-flame section 2-3 of fire grate is coal dust firing space 12, and one or more low NO are installed on the furnace body wall of side, coal dust firing space
xVortex burner 3, it is made up of airduct 3-2, a secondary air channel 3-1, and coal dust sprays into the stove internal combustion by an airduct, secondary air channel aftercombustion required air.
During work, rubbish is delivered to fire grate 2 by feed hopper 1 through dispenser 11, and after drying section 2-1, burning zone 2-2, after-flame section 2-3 burned, lime-ash was discharged through slag-drip opening 5.Coal dust is delivered to burner through an airduct 3-2, by low NO
xThe deep or light separation of shade burner is at burner outlet 3-3 and the reflux heat flue gas fire burns that meeting, owing to adopt the pulverized coal bias combustion mode to reach low NO
xThe purpose of burning, secondary wind enters burner by secondary air channel 3-1, because this burner stable burning ability is strong, can be incineration firing stable thermal source is provided, and helps the rubbish efficient burning, when refuse thermal value reduces, does not need fuel oil combustion-supporting.Hot flue gas process waste heat boiler 4 that produces after burning and superheater 9 thereof, economizer 8, air preheater 7 are discharged from flue 10, and the steam that UTILIZATION OF VESIDUAL HEAT IN produces is used for generating from drum 6 discharges.
