Abstract
The utility model relates to a wave-form top of a life-garbage incinerating furnace, wich is composed of the connection of two same arches; the connecting position of the two adjacent arches is provided with a hanging beam; the lower end of the hanging beam and the connecting position of both sides arches form bevel outwards; the top surface of the hanging beam is connected with a draw rod; the arches are fixed on a framework of the furnace body through the draw rod; two end heads of the wave-form top are respectively fixed on the framework of the furnace body. The utility model has the advantages that the mixing of furnace gas is promoted, the stay time of the furnace gas in the furnace is lengthened, and the utility model is good for the sufficient combination of garbage and the uniformity of the combination.
Description
The utility model relates to the wave furnace roof of a kind of furnace roof of incinerator, particularly domestic waste incineration.
The vertically single flat-top furnace roof of living that pushes up of the most employings of the domestic waste incineration of China's production at present, the furnace roof of this structure makes flue gas at the residing time in furnace weak point, and radiating surface is little, and the flue gas of horizontal arch is unfavorable for even burning only in the cross section cocycle.
The purpose of this utility model is to provide a kind of new-type wave formula top construction, promotes the mixing of furnace gas, and prolongs the time of staying of furnace gas in stove, is beneficial to the burning of rubbish.
This wave furnace roof is the broad formula furnace roof that is formed by connecting by two arches.Its design philosophy derives from " hanging the dam by the feet " theory about the mobile aspect of furnace gas that Ye Siman (Yesmann) is founded, and this theory is inferred out from the hydraulic similarity principle.This theory is thought: the furnace roof of curtain wall in the stove or stove joint (reducing) all is equivalent to the dam of hanging by the feet, the streamflow regime that the situation that gas flows below it is equivalent on the dam reverses, the end opening air communication of furnace roof is crossed viscous force and is close, the air-flow of furnace bottom mixes mutually and flows simultaneously, can make the air-flow near furnace bottom produce recirculation.
The corresponding respectively top that is installed on body of heater dry section and primary zone of two arches of wave furnace roof (1), arch horizontal setting corresponding to the dry section top, arch and horizontal plane corresponding to the top, primary zone form an angle, make the rubbish of this arch and body of heater below transmit the fire grate almost parallel.Two arch junctions are connected with a hanging beam (2) of being made by heat-resisting steels, the both sides, lower end of this hanging beam have the inclined-plane, are convenient to accept with the arch abutment head of both sides, and locate by fairlead the front and back end of hanging beam, its end face is connected with pull bar (3), by pull bar (3) hanging beam is fixed on the body of heater skeleton.
Advantage applies of the present utility model is in the following areas:
1, this furnace roof can cause many turbulent flows, makes coefficient of friction become very big, because the increase of frictional force makes air flow slows, promotes the mixing of furnace gas, prolongs the time of staying of furnace gas in stove, and high-temperature flue gas is reflexed to the material end.
2, in the junction of two arches, furnace roof stopping of being caused that have a down dip makes part of smoke skim over from the bed of material, more helps burning.
3, waste incineration has regionality in the burner hearth, and is inconsistent along its length, and the furnace temperature height is uneven, and the flow of flue gas of wave furnace roof can be beneficial to the uniformity of burning.
4, the interaction energy of hanging beam with the heat radiation of furnace roof to the bed of material, but since incinerator in temperature low, radiation is very weak, this effect and not obvious, on the contrary, the smoke convection effect of wave furnace roof just becomes main.
Also in conjunction with the accompanying drawings structure of the present utility model is described further below by an embodiment.

See also Fig. 1, Fig. 2 and shown in Figure 3, the wave furnace roof 1 of the utility model incinerator is formed by connecting by two arches, the thickness of arch is 430mm, the corresponding respectively top that is installed on body of heater dry section 4 and primary zone 7 of two arches, the rear and front end is fixed on the body of heater skeleton, corresponding to the arch horizontal setting of dry section 4 tops, the arch and the horizontal plane of 7 tops, primary zone form an angle, make the rubbish of this arch and body of heater below transmit the fire grate almost parallel.A hanging beam 2 of being made by heat-resisting steels is equipped with in two arch junctions, the both sides, lower end of this hanging beam 2 have the inclined-plane, be convenient to accept with the arch abutment head of both sides, the high 800mm of hanging beam, the equal in length of its length and arch, locate by fairlead two terminations of hanging beam 2, and its end face is connected with pull bar 3, and the other end of pull bar 3 is fixed on the body of heater skeleton.
See also Fig. 4 again, the wave furnace roof is installed and used view in domestic waste incineration, rubbish from hopper 3 accesss to plant, transmit 4 preheatings of fire grate epimere dry section through rubbish after, enter primary zone 7 again and fully burn, the lime-ash of after-flame is discharged by dirt-excluding groove 15.Be positioned at dry section 4 and primary zone 7 that rubbish transmits fire grate 9 tops, be connected with wave furnace roof 1 on the body of heater skeleton, when rubbish burns on fire grate, flue gas can form many turbulent flows 1 time at furnace roof, makes coefficient of friction become very big, because the increase of frictional force, make air flow slows, promote the mixing of furnace gas, prolong the time of staying of furnace gas in stove, and high-temperature flue gas is reflexed to the material end.And in the junction of two arches, furnace roof stopping of being caused that have a down dip makes part of smoke skim over from the bed of material, more helps burning.Waste incineration has regionality in the burner hearth in addition, and is inconsistent along its length, and the furnace temperature height is uneven, and the flow of flue gas of wave furnace roof can be beneficial to the uniformity of burning.
