Description
Technical field
What the present invention proposed is the method for the building materials raw material production of building materials field, specifically utilizes domestic refuse to produce the method for ceramic light aggregate.
Background technology
Before the present invention proposed, the ceramic light aggregate of using at building materials field mainly contained haydite, haydite usually with clay, shale powder, flyash etc. contain sial and calcareous raw material under hot conditions, fire form have a granular texture building materials raw produce.
Application of city life garbage mainly is by the daily domestic refuse that abandons of people, comprising foodstuff, clothing shoes cap, apparatus class, wrapping material class, sanitary product class, toys etc., can be divided into: animal-plant kind, glass-ceramic class, metal species, organic-inorganic fiber-like, high molecule plastic class, electric type, earth class, lime-ash class etc. from the material aspect.Domestic refuse is mainly handled by the mode of burying at present, but severe contamination water source and ambient air, and discharge poisonous and hazardous gas or material, contaminate environment, and take large-area soil.Handle by the incendiary mode in addition, be used for generating or heat supply though can obtain heat in the process of incineration firing, be easy to generate poisonous gas and dust, especially the generation of Dioxins more threatens human life security.Having by domestic refuse stacking fermentation, the generation methane gas acts as a fuel and utilizes.In domestic refuse, also can isolate useful material and carry out cycling and reutilization.Though above life refuse processing method can produce certain treatment effect, all exists the pollution problem once again that is difficult to overcome.
Exist useful material in domestic refuse, how reaching the best effect of utilizing of the acquisition of the property eliminated utilization up hill and dale is the problem that is worth infiltrating research and solution.Especially domestic refuse being transformed into ceramic light aggregate is used for the production of building materials and the light body of application build, high-strength energy saving building product it more can become rubbish and is important large available resource, not only solved the innocuity treatment problem of domestic refuse, and solved the acquisition problem of building materials raw materials, and can save a large amount of soils and energy consumption, make buildings reach energy-conservation and technique effect environmental protection simultaneously.
Summary of the invention
In order to utilize domestic refuse to produce the raw material of ceramic light aggregate as building materials, the present invention proposes a kind of method of utilizing domestic refuse to produce ceramic light aggregate.The slag charge sintering that this method is produced by domestic refuse spontaneous fermentation and degraded back changes the technical problem of ceramic light aggregate into.
The present invention solves the scheme that its technical problem takes:
1. raw material is handled: domestic refuse is carried out sorting, select article and the material being convenient to utilize, as granulating raw material;
2. granulation: become mud with adding the water stirring after the granulating raw material pulverizing, make blocky-shaped particle, as the prebake raw material;
3. oven dry: after the prebake raw material stoving, as the destructive distillation raw material;
4. destructive distillation: the destructive distillation raw material is heated under no air conditions, make organism wherein be decomposed into inflammable gas, from particle, deviate from, and in particle, form hole, as preheating material;
5. preheating: the raw material of preheating is carried out thermal pretreatment, as raw materials for sintering;
6. sintering: will carry out sintering through the raw material of preheating, and become the ceramic light aggregate piece;
7. cooling: will become the cooling ceramic light aggregate through the hot ceramic light aggregate piece cooling of agglomerating;
8. finished product: will pulverize and screening through overcooled ceramic light aggregate, classification becomes the ceramic light aggregate finished product of size fractionated;
The combustible gas that is produced in the retort process is as the sintering thermal source, and organism cut wherein is converted into carbonic acid gas and water after by the high-temp combustion layer, eliminates the pollution of Dioxins objectionable impurities.
The inventive method beneficial effect is: simultaneously domestic refuse is transformed into ceramic light aggregate and heat and is used for the production of building materials, realize complete harmless treatment.The gained ceramic light aggregate can be used as application such as light skeletal that building materials produce, sewage disposal, soil improvement, section bar weighting material, the environmental pollution of utilized waste, saving the soil, stopping rubbish.The harmless treatment of suitable domestic refuse and the production of producing the building materials raw material.
Description of drawings
Fig. 1 is a production scheme of the present invention
Among the figure, 1. raw material is handled, 2. granulation, 3. oven dry, 4. destructive distillation, 5. preheating, 6. sintering, 7. cooling, 8. finished product.
Embodiment
1, raw material is handled
Domestic refuse is carried out sorting, select article and the material being convenient to utilize, as granulating raw material;
2, granulation
Become mud with adding the water stirring after the granulating raw material pulverizing, make blocky-shaped particle, as the prebake raw material, water ratio reaches below 10%;
3, oven dry
After the prebake raw material stoving, as the destructive distillation raw material;
4, destructive distillation
The destructive distillation raw material is heated to 200 under no air conditions, makes organism wherein be decomposed into inflammable gas, from particle, deviate from, and in particle, form hole, as preheating material;
5, preheating
With raw material thermal pretreatment under 500 conditions of preheating, as raw materials for sintering;
6, sintering
To under 1050～1500 temperature condition, carry out sintering through the raw material of preheating, become the ceramic light aggregate piece;
7, cooling
To become the cooling ceramic light aggregate through the hot ceramic light aggregate piece cooling of agglomerating;
8, finished product
To pulverize and screening through overcooled ceramic light aggregate, classification becomes the ceramic light aggregate finished product of size fractionated.
The combustible gas that is produced in the retort process is as the sintering thermal source, and organism cut wherein is converted into carbonic acid gas and water after by the high-temp combustion layer, eliminates the atmospheric pollution of objectionable impuritiess such as Dioxins.
Preheating, destructive distillation and sintering also can use other thermal source, as coal, oil or gas.
The flue gas that the raw material sintering process is produced carries out the desulfurization and decarburization dust removal process by desulfation dust-extraction device, reaches the innoxious emission standard of flue gas.
