Technical field
The invention belongs to the critical piece incineration furnace grate that solid waste incineration is handled, specifically, relate to the Lateral alternate arranged grate of incinerator and compensation device of domestic waste.
Background technology
The most important parts of incinerator are the incineration furnace grate systems.The incineration furnace grate system is responsible for the interior rubbish of stove and transports, and improves rubbish and Air mixing and disturbance degree simultaneously, improves efficiency of combustion.
Existing polytype now burning fire grate comes out especially so-called reciprocating type burning fire grate.The fire grate segment of reciprocal grate form overlaps regularly as roof sheet tile, forms the supporter of incineration firing.Fire grate segment that can seesaw and fixed grate film interleaved, its relative motion cause that rubbish is to forward and backward motion.On reciprocating type promotion fire grate, waste layer is by continuous upset and stirring consumingly, makes waste layer loose repeatedly and rearrange.
At present, it is low that Chinese rubbish has a calorific value, and characteristics such as moisture height are stabilized in more than 850 ℃ for guaranteeing the incinerator outlet temperature, need pile up sufficiently high rubbish on fire grate.Therefore, require fire grate segment can comprehensive, sufficient upset, stirring and the loose whole rubbish bed of material, to shorten drying time, to improve efficiency of combustion.Simultaneously, owing to Chinese house refuse water content height, complicated component, easily clump together, form piece when causing drying garbage and burning.Therefore also require fire grate segment to reduce that rubbish is agglomerating, the possibility of caking, the rubbish diplomatic corps in enough fully contacts with wind energy, drying is abundant, completing combustion, to reduce hot burn decrement rate.
Through the development of last 100 years, though multiple version has appearred in fire grate, fire grate is neat the layout at horizontal direction, following problem in use occurs:
1. the head of single fire grate is neat plane, and the boss or the end face of single fire grate also are neat plane simultaneously.Under nature, rubbish has identical motion state at the fire grate system horizontal direction, and no relative motion trend has increased the possibility that rubbish is agglomerating, lump.
2. when fire grate moved, the neat plane of forming with the head of single fire grate promoted rubbish, makes the rubbish of horizontal direction do being synchronized with the movement of longitudinal direction.Therefore, fire grate segment only stirs and the rubbish that loosens at longitudinal direction, and is not obvious to the rubbish influence of horizontal direction, to the stirring and the loose DeGrain of the whole rubbish bed of material.
3. in addition, because single fire grate boss or end face are the plane, during the fire grate motion, rubbish does not have further at horizontal direction and falls, and fire grate does not have extruding, breaks up effect the rubbish of horizontal direction simultaneously.Therefore fire grate segment is broken up DeGrain to the rubbish of conglomeration, one-tenth piece.
The version that the single fire grate segment crosswise fixed of tradition usually adopts is, all is processed with bolt hole in the fire grate segment both sides, and the fire grate segment that a slice is another connects into integral body by bolt.In use, following problem often appears:
1, because the installation and removal of bolt can only be carried out at the air compartment of fire grate bottom, cause installation, the replacing and difficult in maintenance of fire grate segment, the time of cost is many, and the working environment of workers is abominable.
2, transversely all adopt bolt to connect between the two adjacent fire grate segments, cause bolt quantity too many, the efficient of installing, dismantling is low, labor strength is big.
3, fire grate segment is heated when inhomogeneous, and deflection is unequal, can bigger gap occur between fire grate segment, causes leakage slag, and lime-ash enters in the air compartment by the gap, makes the wind supply quantity instability.
4, after the gap occurring between the fire grate segment, extremely inconvenient with the adjustment in the gap between the grate furnace screening, especially the fire grate plate that is connected to form side by side one by one by a plurality of fire grate segments can't integrally-regulated gap.
