Description

Self-burning type refuse incinerator

The utility model belongs to combustion apparatus.

Generally all there is the inadequate problem of incineration firing in the conventional garbage incinerator, fully burns for making rubbish, often increases combustion-supporting fuel again, at this moment makes power consumption bigger again, and the also unfavorable shortcoming of effect.

The purpose of this utility model is a kind of self-burning type refuse incinerator of development, and this stove need not add combustion-supporting fuel to general rubbish just can make incineration firing abundant.After meeting rubbish difficult combustion or that need specially treated and adding combustion-supporting, can make it reach the purpose of abundant burning and discharge standard.

The utility model stove is realized its purpose by following measure.The first is provided with double-layer grate up and down in flue, and then two combustion chambers about forming, inflammable rubbish elder generation is put in the lower floor combustion chamber, and the incineration firing in the lower floor combustion chamber is at first dried the rubbish of the difficult combustion in upper strata and is heated, and makes the also easy sufficient combustion of upper strata rubbish.It two is that the liner of flue is made the wave structure, can not be fully when making the rubbish filling and inboard wall of furnace be adjacent to, reserve the flowing space of air when burning, be beneficial to rubbish and fully burn.It three is bigger for the space that makes rubbish and inboard wall of furnace, is provided with the rubbish cage in the centre of flue, and rubbish is contained in (below inflammable, difficult combustion in the above) in the cage by different level.It four is when meeting the rubbish of more difficult combustion or requiring the heart just to allow the rubbish (rubbish of hospital) of discharging after must completing combustion, increase liquefied gas combustion-supporting.It is five for keeping the temperature in the flue not scatter and disappear, favourable burning, and the not high favourable safe handling of stove hull-skin temperature has been dosed heat preservation rock between stove outer covering and furnace internal-lining.

The utlity model has floor space little (be similar stove 1/3rd), cost is low, simple to operate, operating cost is low advantage.It also has furnace temperature height (900～1100 ℃), firing rate is fast, treating capacity is big advantage.It has the characteristics of sufficient combustion, pollution-free, emission matching standard again.Its soot emissions blackness is less than 1 grade of Lin Geman, and the concentration of emission of nuisance is less than 90mg/Nm in the flue dust ³, the CO discharge capacity is 2kg/h, SO ₂Discharge capacity is zero, all meets CJ3036-95 incinerator for medical garbage environmental health standards, GB13271-91 boiler air pollution emission standard, GB16297-96 atmosphere pollution comprehensive discharge standard, GB3995-96 ambient air quality, GB14554-93 odorant pollutant discharge standard.This stove applicability is extensive, and it can be used for the garbage disposal in places such as office, school, station, harbour, airport, passenger boat, resident.This stove also has characteristics safe in utilization, and the furnace shell hull-skin temperature is lower than 40 ℃.

Fig. 1 is an overall structure cutaway view of the present utility model, and Fig. 2 is the structural representation of embodiment two, three, and Fig. 3 is the section plan of wave refractory cement lining 5, the structural representation of Fig. 4 shutoff 17.

Embodiment one: present embodiment is made up of furnace shell 1, flue 2, lower floor's fire grate 3, upper grate 4, shoot door 6, lighting door 7, filler door 8, end socket 9.Flue 2 is fixed on the inside of furnace shell 1, is fixed with the furnace lining 5 of one deck wave refractory cement in the inside of flue 2.Shoot door 6 is arranged on the bottom of furnace shell 1, is fixed with lower floor's fire grate 3 in the furnace lining 5 on shoot door, is provided with lighting door 7 on the furnace shell 1 on lower floor's fire grate 3, and lighting door 7 also can be used for filler.Be fixed with upper grate 4 in the furnace lining 5 on lighting door 7, form first combustion chamber 10 between upper grate 4 and lower floor's fire grate 3, end socket 9 is fixed on the top of furnace shell 1, on upper grate 4 below end socket 9 between formation second combustion chamber 11.Filler door 8 is arranged on the top of furnace shell 1.

Embodiment two: the difference of present embodiment and embodiment one is, centre in furnace lining 5 is provided with the cage 12 of a load garbage, cage 12 is fixed on the top of lower floor's fire grate 3, and upper grate 4 is fixed in the middle of the bottom of cage 12, and the overall diameter of upper grate 4 is less than the internal diameter of cage 12.Other composition is identical with embodiment one with annexation.

Embodiment three: be slipped to smoothly in first combustion chamber 10 for making rubbish, present embodiment is designed to decurved arc 13 with the upper grate 4 of embodiment two, for making the steadiness of cage 12 in furnace lining 5, be provided with crossbeam 14 in the upper end of cage 12, crossbeam 14 links to each other solid with flue 2, other composition is identical with embodiment two with annexation.

Embodiment four: for reaching discharge standard behind the incineration firing that makes difficult rubbish that fires or hospital, present embodiment has a tapped port 15 on the furnace shell 1 of first combustion chamber, 10 correspondences, liquefied gas combustion-supporting 16 is screwed on the furnace shell 1 by port 15, carry out combustion-supporting to rubbish in the stove, in the time need not using combustion-supporting, port 15 is sealed by a shutoff 17.Other composition is identical with embodiment three with annexation.

Embodiment five: do not scatter and disappear outside furnace shell for keeping the temperature in the furnace lining, be filled with heat preservation rock 18 between flue 2 and furnace shell 1.Other composition is identical with embodiment four with annexation.
