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, 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 compound furnace grate device of theoretical foundation for industrial applications.
Technical scheme of the present invention is as follows: a kind of compound furnace grate device, fire grate support frame (4) has the two symmetrically arranged longerons (4a) in left and right, fire grate support frame (4) is provided with standard fire grate module, this standard fire grate module is made up of the multistage standard fire grate module (5) of arranging successively from front to back, the all front high rear low dip of each standard fire grate module (5) is arranged, and every primary standard fire grate module (5) is formed 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 two longerons (4a), each crossbeam (4b, end 4c) is fixed with corresponding longeron (4a) by channel-section steel, the fixed grate front end of rear stage 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) arranged, the end sleeve of the 3rd crossbeam (4d) is loaded on column (4e), lower end and the longeron (4a) of column (4e) 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 framework, and under the suitable backstepping track of platform framework guides, can rotate, to simulate the true operating state of fire grate system around forwards dead axle point or backstepping dead axle point.When standard fire grate module backstepping rotates, 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; When standard fire grate module forwards rotates, 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, break up, loosening rubbish, realizes the mean residence time of material particles, volume flow rate test; The present invention can complete comprehensive and systematic along backstepping fire grate, test result under regulating according to various parameter, Comprehensive Correlation material particles mean residence time, volume flow rate parameter, the structural parameters be optimized and kinematic parameter, for industrial applications provides theoretical foundation.
Described standard fire grate module adopts above structure, not only simplify assembly technology, reduces the difficulty of assembling, and effectively reduce the labour intensity of workman, substantially increase efficiency of assembling; The modular structure that multistage standard fire grate module is formed is simple, compact, easy accessibility, quick.Drive unit provides power in moving grate rear end, makes moving grate reciprocating on the backboard of fixed grate, effectively can stir, break up, loosening rubbish, thus the effect that ensure that.
In the end the moving grate rear of primary standard fire grate module (5) is provided with splicing plate (3), and this splicing plate (3) is fixed by bolt and fire grate support frame (4), and the upper hole supplying bolt to pass of splicing plate (3) is the strip hole moved towards up and down.Above structure is conducive to splicing, and the height and position adjusting splicing plate is very convenient.
