Abstract
The invention relates to grease-containing waste clay ceramsite and a preparing method thereof. According to material proportion, the grease-containing waste clay ceramsite comprises 60%-80% of grease-containing waste clay powder and 20%-40% of pulverized fuel ash. The process flow is that stoving, levigating, sieving and metering the grease-containing waste clay powder, conveying the grease-containing waste clay powder and the pulverized fuel ash to a stirrer for dry stirring for about 1.5 minutes, adding 1/2 water for wet mixing for about 2.5 minutes, stirred wet powder materials are sent into a balling disc for balling by adding water again, placing waste clay ceramsite raw materials into a double-layer continuous pulverized fuel ash ceramsite sintering furnace for sintering, and finally cooling, crushing and selecting the waste clay ceramsite raw materials after drawing. The grease-containing waste clay ceramsite and the preparing method thereof are characterized in that combination of the grease-containing waste clay and the pulverized fuel ash solves problems of pollution to the environment caused by grease-containing waste clay solid waste and pulverized fuel ash solid waste, and ceramsite sintering needs no coal or soil, thereby saving energy and land. Ceramsite products prepared with the method meet national standard requirements, so that the grease-containing waste clay ceramsite and the preparing method thereof really achieve environmental improvement and development and utilization simultaneously, and meet development requirements for circular economy of our country.
Description
Technical field
The present invention relates to building materials manufacturing technology field, is a kind ofly to utilize the useless carclazyte of grease that contains in the grease processing industry to be main raw material(s) specifically, and flyash is less important starting material, makes to contain useless carclazyte haydite of grease and method of manufacture thereof.
Background technology
Since nineteen fifties, Britain utilizes industrial residue--flyash the earliest in the world, produces lytag.China in 1964 in Tianjin silicate product factory and Lanzhou built up two production lines of sintering flyash ceramic grain, started the climax of total utilization of PCA again up to the nineties, China is a big coal country; It is again coal fired power generation big country; Comprehensive utilization flyash has caused the great attention of country, proposed the STRATEGIES OF SUSTAINABLE DEVELOPMENT policy, so the mode of total utilization of PCA is a lot; Technology is comparative maturity also, such as flyash ceramisite sintered be exactly one of the mode of mainly utilizing.
Since the reform and opening-up, the grease processing industry of China has had development at full speed, in greasy refining process, usually adds oil and weighs 2%～5% atlapulgite and carry out adsorption bleaching, the staple in the useless carclazyte after the decolouring; SiO

2O, neutral grease, natural pigment, fatty acid etc.Useless carclazyte after the decolouring is the grease of absorption 20%～50% usually.In order to reduce greasy adsorptive capacity in the atlapulgite, grease processing enterprise relies on technical progress, and the one, adopt the novel process that reduces the atlapulgite consumption, the 2nd, adopt milling process, solvent method and aqua method that the grease in the useless carclazyte that decolours is extracted recovery repeatedly.Final contain fat content in the useless carclazyte of grease less than 10%; These are contained the useless common treating method of carclazyte of grease; Be to bury, contain the useless carclazyte of grease and not only pollute the environment, jeopardize groundwater quality as waste; And contained grease is when being high unsaturated oil, and useless carclazyte contact also easy generation spontaneous combustion and causes fire with air.In order to develop a circular economy; Realize the STRATEGIES OF SUSTAINABLE DEVELOPMENT policy; Must carry out the development and use of resource utilization to the useless carclazyte of grease that contains of grease processing enterprise discharging, reduce contaminate environment, the generation of stopping Serious Accident; Causing heavy losses with the exempt from customs examination the people's lives and property, is a new problem of demanding urgently researching and solving.
It is main that the present invention attempts to contain the useless carclazyte of grease, mixes a certain amount of flyash, need not any sticker; Without extra fuel, produce a kind of useless carclazyte haydite of grease that contains, this kind waste is fully utilized; Reach the purpose of recycling economy, sharp useless, environmental protection, energy-conservation.Contain the filtration medium that the useless carclazyte haydite of grease can be used for material of construction, municipal sewage treatment, tap water filter and chemical industry.
Summary of the invention
The objective of the invention is to: fill up the blank that contains the useless carclazyte recycling of grease, a kind of science of selecting materials, reasonable ratio are provided, need not be native, without coal, single with a kind of useless carclazyte haydite of grease and method of manufacture thereof of containing of these two kinds of solid waste sintering.
Technical scheme of the present invention is achieved in that a kind of useless carclazyte haydite of grease and method of manufacture thereof of containing: first material and proportioning, it two is technological process of productions.
A kind of useless carclazyte haydite of grease and method of manufacture thereof of containing of the present invention includes and contains the useless carclazyte of grease, flyash; Have the chemical ingredients and the physicals of independent formation haydite though contain the useless carclazyte of grease, owing to itself contain the grease height, the internal combustion heat is too high when sintering ceramsite; The haydite intensity of not only producing is low, and also coking easily of haydite, needs the lower flyash of a certain amount of loss on ignition of admixture; Make that the heat of these two kinds of waste internal combustions is complementary; Reach a mean state, can not only reach the required enough internal combustion heats of sintering ceramsite, haydite is noncoking also; Can also improve the strength grade of haydite, enlarge sharp useless effect.
Weight proportion:
Contain the useless carclazyte powder 60～80% of grease;
Flyash 20～40%;
Manufacturing process flow:
1. will contain the useless carclazyte oven dry of grease, levigate after, sieve with the square hole sieve of 0.3mm, its 0.3mm tails over part and returns levigately again, the 0.3mm square hole sieve sieve end, contain the useless carclazyte powder of grease, as the main raw material(s) of production haydite;
2. contain the useless carclazyte powder of grease after will sieving, flyash measures respectively;
3. two kinds of materials that will measure are rendered in the stirrer, and earlier dried stir about is 1.5 minutes, after add 1/2 water, rewetting stir about 2.5 minutes;
4. the wet powder after will stirring is sent in the pan-pelletizer, adds 1/2 water again, the rotating centrifugal balling-up;
5. will contain the useless carclazyte haydite raw material ball of grease; Insert roasting in the flyash ceramisite sintered kiln of a kind of static double layer continuous formula; 1220 ℃～1350 ℃ of sintering temperatures, sintering time 2.0～2.5 hours contains the useless carclazyte haydite raw material ball of grease in sintering oven; Pass through preheating, sintering, three operation stages of cooling successively, below kiln internal cooling to 300 ℃;
