Wherein, household garbage particles is selected from through pulverizing, sorting and dehydration pretreatment combustiblematerials particle.
The present invention also provides a kind of preparation method who is mixed with the architecture sediment sludge baked brick of household garbage particles, may further comprise the steps:
(1) architecture sediment and mud collection: the exploitation architecture sediment, subsequent use after storing ageing, municipal sludge is stacked evenly subsequent use;
(2) batching: the architecture sediment and the municipal sludge of said weight percent are mixed, stir moisturizing the time then, even until moisture, denseness is moderate;
(3) domestic refuse collection: household garbage particles is selected from through pulverizing, sorting and the pretreated combustiblematerials particle of dehydrating step;
(4) fuel screening: get said fuel by said mass percent, the screening of broken back, the preparation particle diameter is subsequent use less than the particle of 3mm;
(5) fuel is mixed and is joined: above-mentioned fuel particle is spiked in the mixture of above-mentioned architecture sediment and municipal sludge, utilizes stirrer to stir;
(6) extrusion molding: utilize mud extruder that above-mentioned mixed raw material is pushed, on brick cutting machine, cut base then and form adobe;
(7) drying: adobe piled up in the base field carry out natural drying, be aided with the kiln drying means then and carry out artificial seasoning;
(8) roasting, finished product: in annular kiln, carry out sintering to above-mentioned through dried adobe, the agglomerating temperature is 945～1000 ℃, and kiln discharge promptly makes this product then.
The present invention compares prior art and has the following advantages: the present invention has made full use of urban architecture dregs, municipal sludge the like waste, and the vitrified brick physical and mechanical property of processing is superior, and production cost is low, and energy-conserving and environment-protective.Adopt the flammable organism that sub-elects in the domestic refuse to substitute wood chip, stalk etc., raw material sources extensively, be easy to get, production cost is low.But the flammable organism spontaneous combustion in roasting process in the domestic refuse, conserve energy forms vesicular structure after the roasting simultaneously in vitrified brick, improved heat-insulating property, again domestic refuse has been carried out recycling, environmental protection and energy saving.
