Description
Technical field
The invention belongs to the critical piece pyrogenation incinerator fire bars of solid waste pyrolytic incineration processing, specifically, especially
It is related to a kind of offal treatment tube furnace based on gear rolling fire bars group.
Background technology
Existing Disposal of Municipal Refuse mainly has burning, landfill, compost, waste separation recycling etc..In rubbish
It handling in routine techniques, burning disposal has reduced training apparent, and innoxious thoroughly floor space is small, and waste heat energy is utilized,
The advantages that secondary pollution is few, meets the strategic requirement of China's sustainable development.
The most important component of wastes thermal decomposition incineration furnace is pyrogenation incinerator fire bars system.Pyrogenation incinerator fire bars system
It is mainly responsible for rubbish in thermal response pipe to transport, while improving mixing and the disturbance degree of rubbish and air, and pass through height fall reality
It now breaks up, improves efficiency of combustion.
There are many burning fire grate of type, especially reciprocating burning fire grates now.The fire grate of reciprocal grate form
Piece is orderly as tile to overlap, and forms the supporter of refuse pyrolysis burning.The movable furnace grate plate that can be moved forward and backward
With fixed grate film interleaved, generates mutually movement and cause moving forward and backward for rubbish.In reciprocating grate on piece waste layer
By strong continuous overturning and agitation, keeps waste layer repeatedly loose and reconfigure arrangement.
Currently, the features such as Chinese rubbish has calorific value low, and moisture is high, stablizes to ensure to burn heater outlet temperature
It 850 DEG C or more, needs to accumulate sufficiently high rubbish on fire grate.It is therefore desirable to fire grate segment can it is comprehensive, it is sufficient overturning,
Agitation and the loose entire rubbish bed of material, to shorten drying time, improve efficiency of combustion.Simultaneously as life in China rubbish is aqueous
Amount height, complicated component cause easily clump together when drying garbage and burning, form block.Therefore also require fire grate segment reduce rubbish at
Group, caking possibility, the rubbish in diplomatic corps can come into full contact with First air, dry fully, completely burned, burnt with improving heat
Lapse rate.
By the development of last 100 years, though a variety of traditional structure forms occurs in fire grate, fire grate is neat in horizontal direction
Arrangement, and be also neatly to move in parallel during exercise, occur problems in use：
1. the head of single fire grate is neat plane, while the boss of single fire grate or top surface are also neat plane.
In its natural state, rubbish increases rubbish in fire grate system horizontal direction motion state having the same, no relative motion trend
The possibility that rubbish is agglomerating, lumps.
2. fire grate moves, rubbish is pushed with the neat plane that the head of single fire grate forms so that horizontal direction
Rubbish makees moving synchronously for longitudinal direction.Therefore, fire grate segment is only in longitudinal direction agitation and loosening rubbish, to the rubbish of horizontal direction
Rubbish influences unobvious, the agitation to the entire rubbish bed of material and loose effect unobvious.
3. in addition, since single fire grate boss or top surface are plane, when fire grate moves, rubbish is in horizontal direction without further
Fall, while fire grate to the rubbish of horizontal direction without squeeze, the effect of breaing up.Therefore fire grate segment sprays conglomeration, blocking rubbish
Dissipate effect unobvious.
4. the air holes that the two adjacent fire grate segment back sides open up in same grate furnace plate-laying is circle, neat along its width direction
Arrangement, and air-out direction is neat Parallel airflow, this allows for First air and reduces with rubbish contact area, increases drying time, from
And slow down incineration treatment of garbage process；And First air is smaller to flue gas flow field disturbance in burner hearth.
5. the traditional fire grate that there is now, the part due to its structure, therefore when installation is more and connection type is numerous
It is trivial, it is difficult to that fire grate segment is installed in the smaller experimental provision in space, therefore is relatively suitble to and large scale industry treatment of urban garbage.
For example following patent of invention of existing waste incinerator：Sawtoothed reciprocating grate bar (CN201120509663.8),
An open question in the fire grate segment (CN200720124765.1) of energy self loosening rubbish：Fire bars form is more traditional and broken
Broken, cutting power effect unobvious；Parts are more, and worker is not easy to install.
