The purpose of this utility model is to provide a kind of firing efficiency height, the burning amount is big, adaptability is strong, operating cost is low, have rotary furnace, the rotary furnace grate furnace of grate furnace and fluid bed three advantage.
For realizing this purpose, the technical measures that the utility model adopts are as follows:
The rotary furnace grate furnace of burning away the refuse, it comprises drying device, stove overcoat tube, stove inner sleeve, ventilating grate, air-blast device, shoot door, burner cover; It is characterized in that establishing at stove inner sleeve middle part ventilating grate, ventilating grate is by radially having a plurality of vent aperture and form in the position at the stove inner sleeve; The stove inner sleeve constitutes the air jacket that communicates with the stove overcoat tube, is connected and fixed by strengthening gusset between stove inner sleeve and the stove overcoat tube, and medium position is established air-blast device in the stove overcoat tube outside, has the air vent that communicates with air-blast device on the stove overcoat tube.
The above-mentioned rotary furnace grate furnace of burning away the refuse, can also on the stove inner sleeve, be provided with raising material unit, raising material unit radially stretches in the stove, raising material unit makes castor row by the heating resisting metal tubing that has air vent and is fixed on the stove inner sleeve, has the hole that air vent with raising material unit is relative and communicate in the stove inner sleeve and the junction of raising material unit.
The above-mentioned rotary furnace grate furnace of burning away the refuse can also be provided with the Coal powder spray device vertically at the middle part of burner cover.
The above-mentioned rotary furnace grate furnace of burning away the refuse, drying device can be shaft furnace formula drying garbage device, grate preheating machine formula drying garbage device, fluidized bed type drying garbage device.
The utility model rotary furnace grate furnace makes rubbish have from inside to outside, reach from outside to inside multiple burning forms such as layer combustion because of add ventilating grate in rotary furnace, and combustion intensity is increased; Raising material unit not only can stir rubbish, makes rubbish be the burning of fluidisation attitude when kicking up being stirred, and improves burning velocity, and has combustion-supporting effect; Drying device can be removed the most of moisture content in the rubbish, improves refuse thermal value, makes the easier burning of rubbish; The Coal powder spray device can be crossed when low at refuse thermal value and regulate the temperature fluctuation that causes because of the rubbish fluctuation by Coal powder spray, because of adopting than the cheap coal dust of diesel oil as auxiliary fuel, has reduced operating cost greatly simultaneously.Advantages such as the rotary furnace grate furnace has the firing efficiency height, combustion intensity is big, adaptability is strong, no easily worn part, burning disposal ability big, low price, operating cost are low.
Fig. 1 is the structure chart of rotary furnace grate furnace;
Fig. 2 is a rotary furnace grate furnace sectional drawing;
Fig. 3 is the raising material unit schematic diagram.
Introduce the structure and the detailed content of the utility model rotary furnace grate furnace below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2, shown in Figure 3, rotary furnace grate furnace of the present utility model mainly comprises drying device 1, stove overcoat tube 2, stove inner sleeve 3, ventilating grate 4, air-blast device 5, raising material unit 6, shoot door 7, burner cover 8.Advance the stove end at stove tail rubbish and be provided with drying device 1, it adopts slipper seal to be connected with stove overcoat tube 2 tail ends, drying garbage device 1 adopts vertical dryer, also can adopt grate preheating machine formula drier, fluidized bed type drier and rotation drum type drier,, discharge the most of moisture in the rubbish by drying device, refuse thermal value improves, make the easier burning of rubbish, drying device 1 is provided with smoke exhaust pipe 12, and flue gas is discharged from smoke exhaust pipe.Establish ventilating grate 4 at stove inner sleeve 3 middle parts, ventilating grate 4 is by radially having a plurality of vent aperture and form in the position at stove inner sleeve 3: stove overcoat tube 2 constitutes air jackets with stove inner sleeve 3, is connected and fixed by reinforcement gusset 10 between stove inner sleeve 3 and the stove overcoat tube 2; Establish air-blast device 5 at stove overcoat tube 2 outside medium positions, have the air vent that communicates with air-blast device 5 on the stove overcoat tube 2, this air vent is covered by air-blast device 5 and communicates with air jacket, air-blast device 5 maintains static, its with stove overcoat tube 2 for slipper seal is connected, establish blast pipe 9 on the air-blast device 5; Ventilating grate 4 is made by high temperature resistant, wear-resisting and acidproof material, combustion air blasts in the stove from ventilating grate 4 through air-blast device 5, make rubbish have from inside to outside, reach from outside to inside multiple burning forms such as layer combustion, combustion intensity increases, and ventilating grate 4 can bear for a long time and surpass 1200 ℃ high temperature; On stove inner sleeve 3, be provided with a plurality of raising material units 6, raising material unit 6 radially stretches in the stove, raising material unit 6 makes castor row by the heating resisting metal tubing that has air vent and is fixed on the stove inner sleeve 3, have the hole that air vent with raising material unit 6 is relative and communicate in the stove inner sleeve 3 and the junction of raising material unit 6, raising material unit 6 can adopt heat resisting steel or steel alloy to make, the tympanites of constantly having time in the raising material unit 6 is gone into and is cooled, making it the life-span improves greatly, raising material unit 6 ceaselessly stirs rubbish, make rubbish be the burning of fluidisation attitude when kicking up being stirred, thereby improved burning velocity; Shoot door 7 is located at burner and goes out the lime-ash end, for preventing that dust stratification is too much in 3 air jackets of stove overcoat tube 2 and stove inner sleeve, needs periodic cleaning; Burner goes out the lime-ash end and is provided with burner cover 8, burner cover 8 adopts slipper seal to be connected with stove overcoat tube 2 head ends, middle part at burner cover 8 is provided with Coal powder spray device 11 vertically, when refuse thermal value is crossed when low, can be by spraying into the temperature fluctuation that coal dust comes stable regulation to cause because of the rubbish fluctuation, keep rotary furnace grate furnace thermal regulation stable, cheap because of coal simultaneously than diesel oil, can reduce operating cost greatly.Be provided with slewing gear 13 in stove overcoat tube 2 outsides, discharge smoothly in the stove for making rubbish smooth combustion and lime-ash, the rotary furnace grate furnace keeps the inclination angle 5～20%.
