Abstract

The utility model provides an RDF gasification combustion furnace for converting domestic and medical garbage into fuel, which belongs to the field of furnaces and relates to the combustion furnace using garbage as fuel. The combustion furnace comprises a horizontal furnace body, wherein the horizontal furnace body is provided with a feed hopper (1), a smoke exhausting and purifying device (9) and a fire grate (8). The RDF gasification combustion furnace for converting domestic and medical garbage into fuel is characterized in that the interior of the furnace body is sequentially divided into a vaporizing chamber (2), a gas buffering chamber (3), a high-temperature combustion chamber (4) and a burnout chamber (5); and the smoke exhausting and purifying device (9) is a desulphurization and dust removal sprinkler. The combustion furnace can use RDF formed by converting garbage as fuel, enough time can be ensured to dry the RDF in the vaporizing chamber (2) so that the RDF can be combusted insufficiently to generate flammable gas, and the flammable gas is treated by secondary combustion in the high-temperature combustion chamber (4) so as to generate heat to be outputted. The combustion furnace can use both domestic and medical garbage as fuel.

Description

Life, medical waste derivatived fuel RDF gasification combustion furnace
Technical field
The utility model belongs to the boiler plant field, and relating to a kind of is the combustion furnace of fuel with rubbish.
Background technology
At present, increasing rubbish constitutes a threat to earth environment and human lives, medical waste heavily contaminated, unmanageable rubbish especially especially, and the human especially extremely urgent significant problem of energy crisis.In fact, contain huge energy in the rubbish, handle if rubbish can be acted as a fuel, the result that can obtain killing two birds with one stone, not only rubbish obtains harmless treatment, has also obtained the energy.
Rubbish acts as a fuel and handles the pernicious gas that produces when key is sufficient combustion and filtering burning.Gasification combustion furnace can make fuel be burnt efficiently, and it makes initial fuel become gaseous fuel earlier, and gaseous fuel helps fully mixing with air, thereby can be fully burned, as the gasifying stalk combustion furnace.The body of heater of gasification combustion furnace comprises gasification combustion chamber and heat combustion chamber, and gasification combustion chamber makes initial fuel become fuel gas, burning again after fuel gas enters the heat combustion chamber and composition of air mixes.Gasification combustion furnace is at the difference of fuel and difference, and the gasifying stalk combustion furnace can not directly use rubbish to make fuel, because the complicated component of rubbish, humidity, purity instability.At present, rubbish can be converted into fuel, it is garbage derivatived fuel, represent that with RDF RDF can burn in general stove, but can not guarantee sufficient combustion, calorific value is lower, and inadequate burning also produces a large amount of pernicious gases, causes secondary pollution, so need a kind of combustion furnace of effectively making fuel with RDF.
Summary of the invention
In order to make rubbish as good fuel, the utility model provides a kind of suitable use rubbish to make the combustion furnace of fuel.
The utility model has adopted following scheme:
Design a kind of life, medical waste derivatived fuel RDF gasification combustion furnace, this combustion furnace is horizontal body of heater, and its above-head is provided with loading hopper, and afterbody is provided with smoke discharging and purifying device, and its inside is provided with the reinforced also fire grate of ash discharge that goes forward one by one to afterbody from the head.Described body of heater inside is cut apart successively to be had, be positioned at from the body of heater head to body of heater the middle part vaporizer, be positioned at the vaporizer back the combustion gas surge chamber, be positioned at combustion gas surge chamber back high temperature combustors, be positioned at the secondary furnace above the high temperature combustors, wherein, passage between vaporizer and the combustion gas surge chamber is positioned at both top, passage is positioned at both bottoms between combustion gas surge chamber and the high temperature combustors, passage between high temperature combustors and the secondary furnace is positioned at both middle parts, and is provided with the air flue that flows into air in the high temperature combustors; Described smoke discharging and purifying device is desulfurization, dedusting spray equipment.
Passage between described high temperature combustors and the secondary furnace is a porous plate.
The chamber of respectively cutting apart in described body of heater and the body of heater is made by concrete.
Described fire grate is a reciprocating fire grate, this fire grate by gearbox by driven by motor.
The major advantage of this device is: 1, the fire grate of overlength is arranged in the body of heater, can make garbage fuel fully dry.2, be provided with the combustion gas surge chamber, stable gas supply can be provided.3, high temperature combustors is provided with special air flue, can obtain more air, and combustion gas is fully burnt.4, be provided with desulfurization, dedusting spray equipment, can effectively remove remaining pernicious gas.5, because sufficient combustion not only can use house refuse to make fuel, can also use medical waste to make fuel.
Description of drawings
Fig. 1 is an example structure figure of the gasification combustion furnace in the utility model
Among the figure: the 1-loading hopper; The 2-vaporizer; 3-combustion gas surge chamber; The 4-high temperature combustors; The 5-secondary furnace; The 6-air flue; The 7-fire hole; The 8-fire grate; The 9-smoke discharging and purifying device.
The specific embodiment
Describe the utility model in detail below in conjunction with embodiment shown in Figure 1.
Combustion furnace in the present embodiment is made with concrete, is rectangular horizontal body of heater.The head of body of heater is a material charging region, and loading hopper 1 is positioned at the top of body of heater head.The bottom of body of heater inside is provided with fire grate 8, and fire grate 8 extends to the body of heater afterbody from the body of heater head, and fire grate 8 is a reciprocating fire grate, and by driven by motor, motor is connected by the motion bar of gearbox with fire grate 8.Motor and gearbox are positioned at the outside of body of heater head.
Be provided with in this body of heater from feeding intake to the space at body of heater middle part, as vaporizer 2, fuel carries out burn incompletely in vaporizer 2, produces a large amount of fuel gas.Vaporizer 2 back are provided with combustion gas surge chamber 3, and the fuel gas that vaporizer 2 produces enters combustion gas surge chamber 3 above the partition wall of vaporizer 2 and combustion gas surge chamber 3.Combustion gas surge chamber 3 back are provided with high temperature combustors 4, fuel gas enters high temperature combustors 4 below the partition wall of combustion gas surge chamber 3 and high temperature combustors 4, be provided with the air flue 6 that is connected with air blast in the high temperature combustors 4, also be provided with the fire hole 7 that is communicated with vaporizer 2, fuel gas fully mixes in high temperature combustors 4 with air and burns.Also be provided with secondary furnace 5 above the high temperature combustors 4, secondary furnace 5 guarantees fuel gas completing combustion.The heat that secondary furnace 5 produces is promptly exported as heating power.In order to guarantee do not have pernicious gas to discharge, contaminated air is connected to smoke discharging and purifying device 9 at secondary furnace 5, and this device adopts the spray means of desulfurization, dedusting, guarantees pollution is dropped to minimum.
The RDF that this combustion furnace can use rubbish to transform acts as a fuel, and RDF has adequate time to be dried in vaporizer 2, is burnt deficiently then, produces fuel gas, and fuel gas produces the heat that is used to export in high temperature combustors 4 second-time burnings.Combustion gas surge chamber 3 in this combustion furnace ensures to high temperature combustors 4 stable fuel gas is provided.
