The utility model discloses a distributions of staggering of recess between the fire grate segment of the fire grate segment group of novel chain grate furnace through will be two rows adjacent, realize coal -fired in operation in -process tightness coal, the stifled eye of wind, air supply evenly to make the coal burning abundant, the cinder phosphorus content reduces, not only environmental protection and energy saving but also the cost is reduced spending. The utility model discloses a novel chain grate furnace simple structure, the practicality is strong, has very strong popularization prospect.
Description
Technical field
The utility model relates to field of combustion equipment, particularly relates to a kind of novel chain grate furnace.
Background technology
Chain grate furnace is a kind of horizontal three backhaul water-fire pipe composite boilers, arranges a branch of threaded flue in drum.About burner hearth, light pipe water cooled wall is equipped with in two sides.Adopt Lightweight chain furnace grate to realize stoker feed, be furnished with air blast, air-introduced machine carries out force ventilation, and scraper type slag extractor is housed realizes automatic ash ejector.Fuel is fallen on fire grate from coal bunker, after entering hearth combustion, flame is upwards folded to by body both sides burning chamber forwards front smoke box to through rear arch refraction, then is turned back in pot by front smoke box and restrain, enter economizer by rear smoke box, then taken out by air-introduced machine and to draw by flue to chimney discharged to air.
As shown in Figure 1, in existing chain grate furnace, fire grate comprises several rows of fire grate segment group 1, because of the needs ventilated, ventilation seam 2 is had between fire grate segment group 1, because each fire grate segment has one fixed width, in ventilation seam 2, so just only there is wind up, and the wind that fire grate segment width does not blow from the bottom up.In adjacent fire grate segment group 1, the groove on each fire grate segment surface is alignment, and the wind of blowout directly clashes into coal sideling, and due to the stop of coal, it is not smooth that the transmission of wind on fire grate segment width is just compared, and is obstructed even completely.If directly cracked between fire grate segment, then easily cause leaking coal, fire grate design is reasonable not, the distribution wind unfair that result in fire grate is even, fuel gas in burner hearth and solid particle mix good not with air, thus it is bad to cause burner hearth combustion situation, and flame temperature is low, causing can not after-flame completely, causes serious environmental pollution and the wasting of resources.
Utility model content
In order to overcome the shortcoming and defect existed in prior art, the utility model provides a kind of novel chain grate furnace.
The utility model is achieved through the following technical solutions: a kind of novel chain grate furnace, comprise sprocket wheel, chain and be erected at many grate furnaces screening group that chain is parallel to each other, separated by ventilation seam between the fire grate segment group of described adjacent two rows, described every grate furnace sheet group includes multiple fire grate segment, be provided with groove between the fire grate segment of described every grate furnace screening group, the groove between the fire grate segment of the fire grate segment group of described adjacent two rows is in staggered distribution.
Further, the groove between described fire grate segment stitches vertical with ventilation.
Further, the described seam that ventilates be by the adjacent two grate furnace screening groups of arranging between the gap tilted upward that formed of inclined plane.
Further, the described width ventilating seam is 5mm.
Relative to prior art, novel chain grate furnace of the present utility model by by adjacent two row fire grate segment group fire grate segment between groove be in staggered distribution, realize fire coal and in running, do not leak coal, the stifled eye of wind, air-supply evenly, thus make coal burning abundant, cinder phosphorus content reduces, and both environmental protection and energy saving again reduced cost.Novel chain grate furnace structure of the present utility model is simple, practical, has very strong promotion prospect.
In order to understand better and implement, describe the utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the structural representation of common chain grate furnace fire grate.
Fig. 2 is the structural representation of novel chain grate furnace of the present utility model.
Fig. 3 is the cloth wind schematic diagram of novel chain grate furnace of the present utility model.
Detailed description of the invention
Refer to Fig. 1-Fig. 3, Fig. 1 is the structural representation of common chain grate furnace fire grate.Fig. 2 is the structural representation of novel chain grate furnace of the present utility model.Fig. 3 is the cloth wind schematic diagram of novel chain grate furnace of the present utility model.Novel chain grate furnace of the present utility model, comprise sprocket wheel, chain and be erected at many grate furnaces screening group 10 that chain is parallel to each other, separated by ventilation seam 11 between the fire grate segment group 10 of adjacent two rows, every grate furnace sheet group 10 includes multiple fire grate segment 12, be provided with groove 13 between the fire grate segment 12 of every grate furnace screening group 10, the groove 13 between the fire grate segment 12 of the fire grate segment group 10 of adjacent two rows is in staggered distribution.
Particularly, the groove 13 between fire grate segment 12 is vertical with ventilation seam 11.Ventilation seam 11 be by the adjacent two grate furnace screening groups 10 of arranging between the gap tilted upward that formed of inclined plane 14.The width of ventilation seam 11 is 5mm.Wind comes to blowing up sideling from the ventilation seam 11 between adjacent fire grate segment group 10, due to adjacent two row fire grate segment groups 10 fire grate segment 12 between groove 13 be in staggered distribution, this makes it possible to there is a good cloth wind action again to the wind that ventilation seam 11 blows up.
Common chain grate furnace fire grate shown in Fig. 1, to the good drainage of wind neither one, causes the uneven of cloth wind like this.And after novel chain grate furnace of the present utility model staggered by the groove 13 between the fire grate segment 12 of the fire grate segment group 10 by adjacent two rows, each groove 13 and adjacent fire grate segment 12 pairs of wind to have the shunting action along groove direction, make cloth wind more even.When be covered with coal in fire grate segment group 10 time, a part of wind directly and coal clash into, a part of wind can flow again in groove, which adds the probability that coal contacts with air, makes coal combustion more abundant.
Relative to prior art, novel chain grate furnace of the present utility model by by adjacent two row fire grate segment group fire grate segment between groove be in staggered distribution, realize fire coal and in running, do not leak coal, the stifled eye of wind, air-supply evenly, thus make coal burning abundant, cinder phosphorus content reduces, and both environmental protection and energy saving again reduced cost.Novel chain grate furnace structure of the present utility model is simple, practical, has very strong promotion prospect.
The utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
