Description
Technical field
The invention belongs to waste incineration and generating electricity technical field, specifically, particularly a kind of composite grate mate of structural parameters adjusting device.
Background technology
Existing technology of garbage disposal mainly contains burning, sanitary landfills, compost, waste recovery etc.The advantages such as in garbage disposal routine techniques, it is obvious that burning disposal has reduced training, and thoroughly innoxious, occupation of land amount is little, and waste heat energy is utilized, and secondary pollution is few, meet the strategic requirement of China's sustainable development.
The most important parts of incinerator are incineration furnace grate systems.Incineration furnace grate system to be responsible in stove rubbish and to be transported, and improves mixing and disturbance degree of rubbish and air, raising efficiency of combustion simultaneously.
Existing polytype transmit bed comes out now, especially so-called reciprocating transmit bed.The fire grate segment of reciprocal grate form overlaps regularly as roof sheet tile, the supporter of composition incineration firing.The fire grate segment that can seesaw and fixed grate film interleaved, its relative motion causes rubbish to forward and backward motion.On reciprocating promotion fire grate, waste layer is by the upset of continuous print consumingly and stir, and makes waste layer repeatedly loose and rearrange.
At present, it is low that Chinese rubbish has calorific value, moisture high, for ensureing that incinerator outlet temperature is stabilized in more than 850 DEG C, needs on fire grate, pile up sufficiently high rubbish.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.Meanwhile, because life in China rubbish water content is high, complicated component, easily clump together when causing drying garbage and burn, form block.Therefore rubbish is agglomerating, the possibility of caking also to require fire grate segment to reduce, and the rubbish in diplomatic corps can fully contact with First air, drying fully, is completely burnt, to reduce clinker ignition loss.
Through the development of last 100 years, though there is various structures form in fire grate, but in existing multiple fire-grating chip architecture, movable furnace grate plate and fixed grate film are independently be installed on the supporting traverse of fire grate system, structure comparison independent dispersion, and driving mechanism connects moved cross beam integral driving arranges movable furnace grate plate more and be synchronized with the movement.Existing fire grate structure is fixed, and can not realize compound and regulate fire-grating chip architecture.
The fire grate system of industrial applications: grate surface inclination alpha, fire grate effective thickness h and fire grate segment installation site structural parameters are all definite values, needs the important feature parameter determined during design; Fire grate stroke s can only carry out adjustment among a small circle, journey error scope δ=± 10mm; Fire grate speed v can regulate when garbage burning factory is tried out, needs to pre-determine adjustable range when designing hydraulic system.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of can provide the composite grate mate of structural parameters adjusting device of theoretical foundation for industrial applications.
