Description
Technical field
The invention belongs to waste incineration and generating electricity technical field, specifically, particularly a kind of compound furnace grate 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, burning disposal has decrement successful, and innoxious thoroughly 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 is responsible for rubbish in stove and is 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, forms the supporter of incineration firing.The fire grate segment that can seesaw and fixed grate film interleaved, its relative motion causes that rubbish is to forward and backward motion.On reciprocating promotion fire grate, waste layer is by continuous consumingly upset and stirring, makes waste layer repeatedly loose and rearrange.
At present, it is low that Chinese rubbish has calorific value, and moisture high, for guaranteeing that incinerator outlet temperature is stabilized in more than 850 ℃, need to 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.Meanwhile, because life in China rubbish water content is high, complicated component, while causing drying garbage and burning, easily clump together, form piece.Therefore also require fire grate segment to reduce the possibility that rubbish is agglomerating, lump, the rubbish in diplomatic corps enough fully contacts, is dried abundant, completing combustion, to reduce hot burn decrement rate with a wind energy.
Development through 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 for being independently installed on the supporting traverse of fire grate system, structure is more independently disperseed, and driving mechanism connection moved cross beam is integral to drive how row's movable furnace grate plates are synchronized with the movement.Existing fire grate structure is fixed, and can not realize compound adjusting 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, important structure parameter that need to be definite 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, need to when design hydraulic system, pre-determine adjustable range.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of can provide for industrial applications the compound furnace grate device of theoretical foundation.
Technical scheme of the present invention is as follows: a kind of compound furnace grate device, fire grate support frame (4) has left and right two symmetrically arranged longerons (4a), on fire grate support frame (4), be provided with standard fire grate module, this standard fire grate module is comprised of the multistage standard fire grate module (5) of arranging successively from front to back, each standard fire grate module (5) is front high rear low dip setting all, and every primary standard fire grate module (5) forms by fixed grate and moving grate, the fixed grate front end of first order standard fire grate module (5) is fixed on first crossbeam (4b), rear end is fixed on second cross beam (4c), described first crossbeam (4b) and second cross beam (4c) are all across the top at two longerons (4a), each crossbeam (4b, end 4c) fixes with corresponding longeron (4a) by channel-section steel, the fixed grate front end of rear primary standard fire grate module (5) is overlapped on the back side of previous stage moving grate, except the first order, the fixed grate rear end of all the other grade standard fire grate modules (5) is fixed on corresponding the 3rd crossbeam (4d) arranging, the end of the 3rd crossbeam (4d) is set on column (4e), the lower end of column (4e) and longeron (4a) fix, the front end of every one-level moving grate is overlapped in the back side of fixed grate at the same level, and the rear end of every one-level moving grate is provided with drive unit (6).
The present invention is arranged on platform support frame, and under the suitable backstepping track guiding of platform support frame, can be around forwards dead axle point or the rotation of backstepping dead axle point, to simulate the true operating state of fire grate system.During the rotation of standard fire grate module backstepping, standard fire grate module together with fire grate support frame around backstepping dead axle point fixed-axis rotation, slide along backstepping gathering sill in the rear end of fire grate support frame, regulate backstepping grate surface inclination alpha, adjustable extent: α=18-45 °, material moving direction is contrary with the standard fire grate module direction of motion; During the rotation of standard fire grate module forwards, standard fire grate module together with fire grate support frame around forwards dead axle point fixed-axis rotation, the front end edge forwards gathering sill of fire grate support frame slides, regulate forwards grate surface inclination alpha, adjustable extent: α=0-18 °, material moving direction is identical with the standard fire grate module direction of motion.As can be seen here, the present invention can effectively stir, breaks up, loosening rubbish, realizes mean residence time, the volume flow rate test of material particles; The present invention can complete comprehensive and systematic along backstepping fire grate, test result under regulating according to various parameters, Comprehensive Correlation material particles mean residence time, volume flow rate parameter, the structural parameters that are optimized and kinematic parameter, for industrial applications provides theoretical foundation.
