Description

Waste incineration furnace body with secondary air inlet
Technical field
The utility model relates to a kind of incinerator.Specifically, be the bulky refuse incinerator body of heater that burns municipal refuse, be particularly useful on the bulky refuse incinerator of day output more than 100 tons per.
Background technology
In the garbage disposal industry, the incinerator of use all is traditional incinerator at present.This traditional incinerator only is provided with wind inlet one time at the furnace bottom of body of heater.Owing to only be provided with air inlet at the furnace bottom of body of heater, so that the carbon monoxide in the burner hearth is more, oxygen is not enough, only can carry out the rubbish near fire grate combustion-supportingly, can't carry out combustion-supporting to the flame in the burner hearth.Because the oxygen in the burner hearth is not enough, so that the efficiency of combustion of this incinerator is lower.Owing to only be provided with air inlet at the furnace bottom of body of heater, can only play combustion-supporting effect again, the slag on the fire grate is not had cooling effect, so that slag is emitting flare just to be discharged from outside the stove, cause a large amount of wastes of heat energy.
The utility model content
Problem to be solved in the utility model provides a kind of waste incineration furnace body with secondary air inlet.Adopt this body of heater, not only can improve firing efficiency, and can avoid the waste of heat energy.
For addressing the above problem, take following technical scheme:
Waste incineration furnace body with secondary air inlet of the present utility model comprises furnace body, this furnace body contains top body of heater and bottom body of heater, described top body of heater protects lining by the refractory brick of metal shell and inside of metal outershell and forms, described bottom body of heater contains metal outer wall and metal inner surface, leaves the spacing as air compartment between metal outer wall and metal inner surface.The bottom bottom of furnace body is wind inlet once.Its design feature is on the metal outer wall of bottom body of heater the secondary air inlet that links to each other with the overfire air fan air outlet to be arranged, the bottom inboard wall of furnace body circumferentially be evenly equipped with radial hole.
The further improvement of the utility model scheme is, the refractory brick of the top body of heater of burning zone top protects the Tangential Wind hole that is evenly equipped with to become at freeze profile whirlwind on the lining circumferencial direction, and this Tangential Wind hole is communicated with described air compartment by pipeline.
The further improvement of the utility model scheme is, described radial hole has two circles at least, and every circle radial hole all is evenly arranged around the metal inner surface of bottom body of heater.
Further improvement project of the present utility model is, is evenly equipped with stay pipe between the metal outer wall of bottom body of heater and metal inner surface, and the two ends of stay pipe are connected mutually with metal outer wall and metal inner surface respectively.
Take such scheme, have the following advantages:
Can be found out by such scheme, because the metal outer wall at the bottom body of heater is provided with the secondary air inlet that links to each other with the overfire air fan air outlet, the bottom inboard wall of furnace body circumferentially be evenly equipped with radial hole, around the body of heater of bottom, provide radially beam wind for burner hearth, not only the slag before coming out of the stove has been played cooling effect, also replenish oxygen in the burner hearth, helped the burning of flame in the burner hearth.Therefore, adopt this body of heater, efficiency of combustion is high.Again because efficiency of combustion is high, when the slag before coming out of the stove is carried out multi-faceted cooling, makes on the heat of slag and move, thereby improved the temperature of hearth combustion section.Owing to can carry out multi-faceted cooling to the slag before coming out of the stove by the radial hole on the secondary air inlet on the furnace body outer wall of bottom and the bottom inboard wall of furnace body, so that the slag temperature of getting rid of is lower, avoid the waste of heat energy.
Again because the refractory brick of the top body of heater above burning zone protects the Tangential Wind hole that the lining circumferencial direction is evenly equipped with to become at freeze profile whirlwind, and this Tangential Wind hole is communicated with described air compartment by pipeline, so that garbage energy accesses further fully burning.

Fig. 2 is the A-A cross-sectional schematic of Fig. 1;
Fig. 3 is the B-B cross-sectional schematic of Fig. 1.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, the waste incineration furnace body with secondary air inlet of the present utility model comprises furnace body, and described furnace body is cylindrical shape, and it is vertical layout.Described furnace body contains top body of heater 1 and bottom body of heater 4, described top body of heater 1 protects lining 102 by the refractory brick of metal shell 101 and metal shell 101 inboards and forms, described bottom body of heater 4 contains metal outer wall 5 and metal inner surface 12,12 spacings that leave as air compartment 11 of metal outer wall 5 and metal inner surface.Body of heater 4 bottoms in bottom are processed with two wind inlets 10, under the installment state, under the furnace body corresponding with this two wind inlets 10 two the first blower fans 8 are installed, the air outlet of two the first blower fans 8 links together by pipeline 9 and two wind inlets 10 respectively, for burner hearth provides wind one time, the burning of rubbish in the burner hearth.
Metal outer wall 5 at bottom body of heater 4 is processed with two secondary air inlets 6, under the installment state, with these body of heater 4 both sides, two secondary air inlets, 6 corresponding bottom second blower fan 7 is set respectively, the air outlet of these two second blower fans 7 is connected with two secondary air inlets 6 by pipeline 9 respectively.Bottom body of heater 4 inwalls circumferentially be evenly equipped with radial hole 3.Described radial hole 3 has two circles at least, and concrete quantity depends on the needs, and in the present embodiment, described radial hole 3 is five circles, and every circle radial hole 3 all is evenly arranged around bottom body of heater 4 inwalls.Blow by secondary air inlet 6, air compartment 11 and 3 pairs of burner hearths of five circle radial holes, when the slag before discharging is carried out multi-faceted cooling, also improved the air themperature that enters in the burning zone.Avoided slag emitting flare just to be discharged from the situation generation that stove is outer, cause a large amount of wastes of heat energy.
For further improving the efficiency of combustion of rubbish, the refractory brick of the top body of heater 1 above burning zone protects the Tangential Wind hole 2 that lining 102 circumferencial directions are evenly equipped with to become at freeze profile whirlwind, and this Tangential Wind hole is connected with described air compartment 11 by pipeline respectively.By secondary air inlet 6, air compartment 11 and Tangential Wind hole 2, make the wind that enters in the burner hearth form whirlwind, so that garbage energy accesses further fully burning.
For blast metal outer wall 5 and the metal inner surface 12 excessive, that make bottom body of heater 4 of avoiding entering in the air compartment 11 is out of shape, metal outer wall 5 and 12 of metal inner surfaces at bottom body of heater 4 are evenly equipped with stay pipe 13, and the two ends of stay pipe 13 are connected mutually by screw bolt and nut and metal outer wall 5 and metal inner surface 12 respectively.
