The invention discloses a method for preparing building ceramisites by means of household garbage incineration bottom ash, and relates to a preparation method for the building ceramisites. The method comprises the steps that 1, the household garbage incineration bottom ash and waste glass powder are mixed to obtain mixed powder; 2, the mixed powder is ground to obtain mixed fine powder; 3, industrial oil sludge and water are mixed to obtain mixed liquid; 4, the mixed liquid is sprayed on the mixed fine powder to obtain small balls, and then the small balls are calcined and cooled to obtain the building ceramisites. According to the method for preparing the building ceramisites by means of the household garbage incineration bottom ash, 100% of solid waste is adopted as the raw materials, and the production energy consumption is greatly reduced by adding the industrial oil sludge; the prepared building ceramisites have the advantages of being high in solid waste utilization ratio, low in water absorption, small in bulk density and high in cylinder compressive strength; the industrial oil sludge is added in the granulation process, therefore, the energy consumption in the ceramisite calcining process can be greatly reduced, and meanwhile the pollution problem of the industrial oil sludge itself can be solved.
Description
Technical field
The present invention relates to the preparation method of building porcelain granule, especially relate to consumer waste incineration bottom ash for main raw material, there is in conjunction with cullet and industrial greasy filth preparation the method for low water absorption, low density and high cylindrical compress strength building porcelain granule.
Background technology
Garbage-surrounded city has become one of main Environmental Problems hindering urban development.One of domestic garbage burning electricity generation most feasible pattern being considered to current refuse treatment, but the recycling of a large amount of consumer waste incineration bottom ash thereupon produced also causes extensive concern and research.At present, the whole world produces the consumer waste incineration bottom ash of several ten million tons every year, and main processing mode is landfill, paves the way and alternative aggregate.Landfill disposal mode not only takies a large amount of land resources, and causes the wasting of resources.And owing to containing a small amount of heavy metal element and Wei Liang dioxin in consumer waste incineration bottom ash.Waste incineration bottom ash simple application may be caused the heavy metal element in consumer waste incineration bottom ash in paving the way Ji dioxin enters underground water along with rainwater, thus polluted water resources, affect human body healthy.
A lot of scientists is had to be devoted to process and the recycling of domestic garbage incineration flyash in the world.But up to now, the utilization of consumer waste incineration bottom ash still rests on simple alternative aggregate or roadbed filling, the high value recycling of consumer waste incineration bottom ash also fails to obtain deep research, also fail really to realize extensive process (Zhang Lixin, the comprehensive utilization of municipal solid waste incineration bottom ashes, the building materials world, 2009,30th volume, the 3rd phase, 136 pages).Reclaiming consumer waste incineration bottom ash, to prepare building porcelain granule be also a new research direction.Building porcelain granule a kind ofly has the environment-friendly building materials that density is little, heat insulating, water-intake rate are low, frost resistance is good, is generally used for replacing the rubble in concrete or the figuline building blocks for the preparation of lightweight.Building porcelain granule is a kind of material of construction with higher-value.But, still rarely have in the world up to now and see with consumer waste incineration bottom ash as main raw material prepares relevant report or the patent of building porcelain granule.2014, the money general of Tongji University reports with domestic refuse incineration ash and cullet for multicellular glass prepared by raw material, but this technique employs the composition that a large amount of silicon-dioxide, sodium carbonate and boric acid regulate cinder from refuse incineration, cause the usage ratio of solid waste to reduce and raw materials cost higher (money is handsome, woods subtracts, Tang Baoshan, solidifies domestic refuse incineration ash with scorification and prepares multicellular glass, silicate journal, 2014,42nd volume, the 1st phase, 108 pages).Therefore, there is provided a kind of with consumer waste incineration bottom ash for main raw material and the low method preparing architecture of high quality haydite of raw materials cost, consumer waste incineration bottom ash utilization ratio and utility value can not only be improved, the consumption of natural resources (clay, shale) can also be reduced, there is higher society, benefits of environment and economy.In addition, improve the quality of product and reduce products production cost, being conducive to promoting applying of environmental protection and energy saving building materials, and reducing building heavy burden and building energy consumption, there are larger market outlook and meet national policy.
Summary of the invention
The object of the invention is to for current consumer waste incineration bottom ash utilising efficiency and be worth low problem, providing one way of life waste incineration bottom ash to prepare the method for building porcelain granule.
The present invention includes following steps:
1) by consumer waste incineration bottom ash and waste glass powder mixing, mixed powder is obtained;
2) mixed powder is ground, obtain mixing fine powders end;
3) industrial greasy filth is mixed with water, obtain mixing liquid;
4) be sprayed on mixing fine powders end by mixing liquid, obtain bead, calcining, namely obtains building porcelain granule after cooling.
In step 1) in, in mixed powder, shared by consumer waste incineration bottom ash, mass ratio is 50% ~ 80%, and mass ratio shared by waste glass powder is 20% ~ 50%.
In step 2) in, described grinding can adopt ball mill by mixed powder grinding 10 ~ 20min, and the rotating speed of ball mill can be 200 ~ 350rpm; The fineness at described mixing fine powders end can be 50 ~ 100 orders.
In step 3) in, the volume ratio of industrial greasy filth and water can be 1: (0.5 ~ 10).
In step 4) in, describedly mixing liquid to be sprayed on mixing fine powders end, mixing fine powders end can be placed on granulating disc by the concrete grammar obtaining bead, is then sprayed onto in the mixing fine powders end on granulating disc equably by mixing liquid spray bottle, forms bead by the rotation of disk; The mass ratio at described mixing liquid and mixing fine powders end can be (4 ~ 9): 20; The diameter of described bead can be 3 ~ 10mm; Bead can be calcined 2min by retort furnace or rotary kiln by described calcining at 1000 ~ 1100 DEG C, and the heat-up rate of described calcining can be 5 ~ 20 DEG C/min; The temperature of described cooling can be 25 ~ 40 DEG C.
The building porcelain granule product that current market is not also prepared for main raw material with consumer waste incineration bottom ash, with be compared with the building porcelain granule prepared of main raw material on the market with solid waste, the building porcelain granule prepared by the present invention has the advantage that utilization rate of solid waste is high, water-intake rate is low, bulk density is little, cylindrical compress strength is high.Add industrial greasy filth in granulation process and greatly can reduce energy consumption in haydite calcination process, the pollution problem of industrial greasy filth itself can be solved again simultaneously.
The solid waste that production technique of the present invention have employed 100% is raw material, and greatly reduces production energy consumption by adding industrial greasy filth.Obtained building porcelain granule has lower water-intake rate, lower density and higher cylindrical compress strength than the similar building porcelain granule of commercial type.
Embodiment
The present invention will be described in more detail for following examples.
The consumer waste incineration bottom ash adopted in the present invention is provided by Chuan Guan environmental protection company limited of Jinjiang City, metal, plastics are separated by the method for mechanical sub-sieve by consumer waste incineration bottom ash, remaining waste incineration bottom ash can directly as main raw material of the present invention, for the production of building porcelain granule.The main component of waste incineration bottom ash is calcium oxide and silicon-dioxide, and its principal element content is as shown in table 1.
