Pottery wind-distributing pipe.Grafting installing type structure designs, and makes the replacing of gasification combustion-supporting wind-distributing pipe 55 become convenient, and working service more closes
Reason, described gasification combustion-supporting wind-distributing pipe 55 is refractory wind-distributing pipe, substantially increases the service life of gasification combustion-supporting wind-distributing pipe 55,
Solve the technical barrier of described gasification combustion-supporting wind-distributing pipe 55 easily ablation.The length of described gasification combustion-supporting wind-distributing pipe 55 is different,
Rotary wind can be formed, so that gasification spray combustion is the most abundant thoroughly in described arch body of heater 51.For making the shortest institute of length
State gasification combustion-supporting wind-distributing pipe 55 and play cloth wind effect, can be by gasification combustion-supporting described in the not grafting of described for part wind-distributing pipe plug socket 54
Wind-distributing pipe 55, this arrangement, make the top of described arch body of heater 51 also have the supply of gasification combustion-supporting wind, thoroughly eliminate gas
Change spray combustion dead angle.
Described sealed feeder unit include rely on rubbish gravity seal Multi-layer material-storing cabinet 3, the bottom of described Multi-layer material-storing cabinet 3 be provided with by
Rubbish advances the material-pulling device of described spray combustion passage 6.Described material-pulling device includes expeller 41, and the connection of described expeller 41 has past
Multiple pusher driving means 42.In the present embodiment, described reciprocal pusher driving means 42 is hydraulic cylinder, naturally it is also possible to use machinery
Or electronic reciprocating motion drive mechanism, these mechanisms are known, and at this, it is no longer repeated.Described expeller 41 constantly will
Part rubbish pushes in the charging aperture 12 of described spray combustion passage 6；Rubbish in described Multi-layer material-storing cabinet 3 is because of height and the effect of gravity
On the one hand the gasification required rubbish of spray combustion it is provided, on the other hand plays the effect of sealing, it is ensured that flue gas will not be excessive.
The bottom of described reciprocating fire grate 2 is provided with secondary wind distribution device 9.In the present embodiment, described secondary wind distribution device 9 is
It is arranged on the wind-distributing pipe of described reciprocating fire grate 2 bottom part down, from the bottom of described reciprocating fire grate 2 to rubbish air feed, it is ensured that
The most fully gasification spray combustion of rubbish, prevents ashes from falling in the gap of described reciprocating fire grate 2.In the present embodiment, remove
Outside the described arch body of heater 51 of reciprocating fire grate 2 correspondence described in latter end, the described arch stove of other described reciprocating fire grate 2 correspondence
Described gasification combustion-supporting device it is correspondingly arranged on body 51.
The step-like setting of reciprocating fire grate, makes rubbish roll through step, mix, loosen, subsequently into
Subordinate's reciprocating fire grate obtains more fully gasification spray combustion, along with rubbish moves to lower under the drive of reciprocating fire grate,
Rubbish sequentially enters drying, gasifying section, gasification spray combustion section, carbonization spray combustion section and slag after-flame section, rubbish in described spray combustion passage 6
The hot blast that rubbish gasification spray combustion produces improves constantly to lower temperature from eminence in described spray combustion passage 6, eventually arrives at bocca
The pollution toxicity gases such as the temperature of 11 can reach 1200 DEG C-1300 DEG C, two English are primarily generated at drying, gasifying section, and part produces
In gasification spray combustion section, carbonization spray combustion section and slag after-flame section no longer produce toxic and harmful, the poisonous and harmful gas of all generations
Body only could enter boiler hot inverting chamber 7 through high-temperature region, and in the process, all harmful gass such as two English is by completely
Decomposing, all unburnt macromole functional groups continue cracking after-flame, finally make rubbish be gasified totally and spray combustion and thoroughly disappear
Except the discharge of the toxic and harmfuls such as two English, it is that the breakthrough shape to prior art is improved, there is great economic benefit and society
Can benefit.
The foregoing is only the schematic detailed description of the invention of the present invention, be not limited to the scope of the present invention.Any
Those skilled in the art, equivalent variations done on the premise of without departing from the design of the present invention and principle and amendment, all
The scope of protection of the invention should be belonged to.
