Specific embodiment
The present invention is described in detail for 1-2 and specific embodiment with reference to the accompanying drawing.
Please referring also to Fig. 1 and Fig. 2, embodiment of the present invention provide a kind of life refuse high temperature cracking gasification furnace body knot
Structure, the chimney 12 including furnace body 1 and set on 1 top of furnace body.Furnace body 1 is equipped with furnace chamber 2 and surrounds the furnace wall 3 of furnace chamber 2, furnace wall
3 inside is equipped with flame retardant coating 14, and the inside of flame retardant coating 14 is equipped at intervals with vertical groove 4, and it is vertical recessed that the outside of furnace wall 3 is equipped with connection
The ventilation opening 5 of slot 4.Chimney 12 is equipped with blower 12.
Life refuse high temperature cracking gasification furnace body structure of the invention when in use, house refuse pour into furnace chamber 2 into
Row burning, during rubbish is fallen from top to bottom, is divulged information into vertical groove 4 by ventilation opening 5, is generated after refuse pyrolysis
Gas is drawn outside furnace body 1 by air-introduced machine 13, and the speed air flow of vertical groove 4 is compared with the speed air flow among furnace chamber 2
It is small, to form pressure difference, make to form negative pressure state among furnace chamber 2, the air circulation among furnace chamber 2 increases, and improves rubbish
Pyrolysis efficiency, promote incineration firing it is complete.
Further, vertical groove 4 is 12.12 vertical grooves 4 are symmetrically located at the inside of flame retardant coating 14.
Ventilation opening 5 is six.Six ventilation openings 5 are symmetrically arranged on the furnace wall 3 connecting respectively with six of them vertical groove 4, each
Vertical groove 4 is correspondingly connected with a ventilation opening 5.
Further, the inside of furnace wall 3 is smooth, reduces rubbish adherency furnace wall 3, improves the pyrolysis efficiency of rubbish,
It avoids furnace wall 3 from corroding and prolongs the service life.
Further, flame retardant coating 14 includes upper section flame retardant coating 141 and lower section flame retardant coating 142.Upper section flame retardant coating 141 is by clay
It is built into refractory brick, withstands at least 1250 DEG C of high temperature.Lower section flame retardant coating 142 is built by high-alumina brick, withstands at least 1350
