The invention provides a device technology configuration method for treating house refuses by using a rotary cement kiln, comprising a pre-treatment device technology configuration method and an incineration device technology configuration method, wherein the whole process of the crushing treatment of the house refuses is implemented by using the pre-treatment device technology configuration method, and a whole incineration process is carried out on the crushed house refuses by using the incineration device technology configuration method; the incineration device technology configuration comprises a double-layer power-driven flap valve, an L-shaped incinerator, a double-layer heavy punch flap valve, a vibrating conveyor and a bucket elevator; and partial tertiary air captured from a tertiary air tube of a rotary kiln enters into the L-shaped incinerator through an air intake tube and high temperature incineration is carried out on the house refuses in the incinerator, smoke generated when incineration passes through an air discharging tube and then is converged with the tertiary air tube, a loop formed by the air intake tube and the air discharging tube of the L-shaped incinerator is provided with a second high-temperature electric butterfly valve and a third high-temperature electric butterfly valve, and a first high-temperature electric butterfly valve is arranged on the tertiary air tube. Harmful gases such as dioxin can be inhibited by high-temperature environment which is generated by using the rotary cement kiln.

A comprehensive garbage sorting technology includes the steps of garbage grinding, bag breaking, magnetic separation, primary winnowing, two-grade sorting in a rotary screen and secondary winnowing. A comprehensive garbage sorting machine comprises a plate-type feeder, a garbage grinding and bag breaking machine and a magnetic separator are mounted in a feeding section and a discharging section of the plate-type feeder respectively, a first winnower and a first U-shaped belt conveyer are sequentially arranged below the discharging end of the plate-type feeder, the rotary screen comprising a first screening section and a second screening section is arranged at the rear end of the plate-type feeder, a first discharging hopper and a second discharging hopper are arranged below the first screening section and the second screening section of the rotary screen respectively, a second U-shaped belt conveyer and a third U-shaped belt conveyer are arranged below the two discharging hoppers respectively, a fourth U-shaped belt conveyer is arranged at the rear end of the rotary screen, and a second winnower is mounted below the discharging end of the rotary screen. The comprehensive garbage sorting technology and the comprehensive garbage sorting machine have the advantages that magnetic metal, building garbage, organic matters and the like in garbage can be sorted out step by step, thorough separation of various materials in household garbage is achieved, and recovery and utilization of useful materials are facilitated.

The invention discloses a renewable energy source system for environmental-friendly treatment of domestic garbage and a technology. The renewable energy source system comprises a vibrating feeder, a shredder, a screening machine, a first shearer, a second shearer, a baking oven, a baking main drum airflow pipeline, a draught fan, a cyclone dust collector, a pelleting machine, a material bin and awater curtain dust collector, wherein the vibrating feeder is arranged on one side of the shredder, and a discharge opening of the vibrating feeder is arranged above a feed hopper of the shredder; thescreening machine is arranged on one side, away from the vibrating feeder, of the shredder; the shredder and the screening machine are connected through a first belt conveyor; the screening machine and the first shearer are connected through a second belt conveyor; and the first shearer and the second shearer are connected through a third belt conveyor. Through the adoption of the renewable energy source system disclosed by the invention, the domestic garbage is made into flammable renewable energy sources through technologies of shredding, screening, shearing, crushing, baking, pelleting andthe like, and waste is turned into wealth, so that the problem of massive accumulation of the domestic garbage is solved to a great extent, and environment pollution caused by the domestic garbage isreduced.

The invention discloses a household garbage incineration fly ash source reduction treatment system and method, and the treatment system comprises a deacidification reaction tower, a classifier and a chelating agent atomization reactor which are sequentially communicated, the bottom of the deacidification reaction tower is connected with a circulating fan, and household garbage incineration flue gas enters the deacidification reaction tower for deacidification treatment; the bottom ash of the deacidification reaction tower enters the deacidification reaction tower again under the action of thecirculating fan to be circulated, the flue gas subjected to deacidification treatment is classified into fine-particle fly ash and coarse-particle fly ash through the classifier, and the fine-particlefly ash enters the chelating agent atomization reactor to be subjected to chelating stabilization treatment for the first time; and the treated fine-particle fly ash and the treated coarse-particle fly ash are converged and subjected to dust removal treatment and secondary chelating stabilization treatment in sequence. According to the method, the consumption of consumables in the flue gas purification process is reduced, the action efficiency of desulfurization and heavy metal fixing agents is improved, the fly ash yield and harmless treatment cost are reduced, and fly ash reduction and efficient stabilization treatment of heavy metals are realized.

The invention discloses a municipal household garbage treatment system which is provided with a bag breaker (1), a belt conveyor (2), a four-axis crusher (4), a vertical type spiral gas floater (5), a dissolved air floater (6), a solid-liquid separator (7), sewage purifying equipment (8) and a garbage treatment station house (10). According to the technical scheme adopted by the invention, municipal household garbage treatment system can be used for deeply treating the municipal household garbage, so that harmful gas in the garbage can be decomposed, harmful substances in the garbage also can be diluted, and part of the substances are floated and circulated, and therefore, labor intensity in a treatment process is greatly reduced, and man power and material resources are greatly saved; the garbage is used as a production raw material, organic substances and inorganic substances in the garbage are separated and are reasonably utilized to produce organic fertilizers and building block materials; and the white pollutants are used for building thermal-insulation materials, so that harmless and recycling treatment of the garbage is realized.
