Description
Technical field
The present invention relates to field of waste resource comprehensive utilization, and in particular to a kind of to utilize the industrial of danger wastes production
Coal and preparation method thereof.
Background technique
Industrial waste source is more, type is complicated, and the general processing system using Concentrate bid focuses on.Especially
It is to there is no clear purposes or the waste containing hazardous chemical ingredient that can not directly utilize at all is listed in hazardous waste and is subject to
Management.The mode that dangerous solid waste is disposed in centralized processing at present can be divided into four kinds of technologies: comprehensive utilization technique, incineration technology, landfill
Disposal technology stabilizes curing technology.Some of them are mostly with steady almost without the complicated inorganic hazardous waste of utility value
Fixedization solidification+landfill stabilization mode；And many complicated organic component class danger solid wastes for originating from the industries such as chemical industry, medicine, pesticide
What is mostly used is incineration disposal technology；And centralized collection burning disposal is limited by the investment and disposing capacity of disposal facility
Deng limitation, often long-term preservation waits burning, and production management and operation to dangerous waste disposal enterprise form serious shadow
It rings；Therefore exploitation targetedly special distributing treatment and use technology, and effective supplement skill as conventional incineration disposal technology
Art is very suitable for concentrating comprehensive utilization in medium-sized and small enterprises or industrial park.
Coal is applied not only to generate electricity in the northern area of China, develops large-scale Chemical Industry, and is also industrial enterprise master
The thermal energy wanted supplies raw material.A large amount of Industrial Boiler, smelting and mineral processing kiln provide coal using lump coal for boiler oil
Gas or power steam provide heat medium or heating for production.With environmental protection it is increasingly strict, it is clear that country has carried forward vigorously coal
Clean utilizing works, wherein industrial shaping coal, water coal slurry combusting technology etc. are the more advanced Coal Clean benefits for being suitble to China's situation
Use technology.
It is used dangerous solid waste as functional form coal briquette bond in the production and processing of industrial shaping coal, a kind of heat is provided
Value, fugitive constituent and the multiple environment-friendly function index such as solid sulphur, smoke abatement, waterproof, combustion-supporting meet the industrial shaping coal of requirement to mitigate
The demand pressure of coal in China, and the utilization report of dangerous solid waste in this regard is also fewer.
Summary of the invention
The object of the present invention is to provide a kind of danger wastes low using calorific value height, ash content to eliminate moulded coal adapted low-quality
The deficiency that ash content of coal is high, calorific value is low realizes that the appreciation to low-quality coal utilizes, that is, utilizes the industrial shaping coal of danger wastes production
And preparation method thereof.
A kind of industrial shaping coal produced using danger wastes, the raw material including following weight parts: danger wastes 1-5
Part, 5-50 parts of coal dust, 0.1-0.5 parts of semi-coke and 0.1-10 parts of water.
Further, the industrial shaping coal produced using danger wastes, the raw material including following weight parts: danger is useless
3 parts of gurry, 20 parts of coal dust, 0.2 part of semi-coke and 5 parts of water.
Danger wastes, according to statistics, the annual hazardous waste yield in the whole world are 3.3 hundred million tons, due to hazardous waste band
Come it is serious pollution and potentially seriously affect, be known as " political waste " public to danger in industrially developed country's hazardous waste
Waste problem is very sensitive, opposes that dangerous waste disposal field, and the disposition expense of hazardous waste are set up in the area lived at oneself
With high, the long-term accumulation of hazardous waste will necessarily generate harm to global environment.
Danger wastes can destroy ecological environment, influence the health of the mankind, and Long Term Contact may cause poisoning, carcinogenic, cause
Abnormal, mutagens etc.；Hazardous waste is not handled or non-standardized treatment dispose brought by the pollution of atmosphere, water source, soil etc. also will be at
For the bottleneck for restricting economic activity.
Coal dust refers to coal of the granularity less than 0.5 millimeter.Coal dust has biggish surface area, the adsorbable a large amount of sky in surface
Gas, to make it have mobility.
Semi-coke is made of the high-quality sieve's dwarf essence coal cinder abounded with using Shenfu coalfield is fired, as a kind of novel carbon
Material, the characteristic high with its fixed carbon, specific resistance is high, chemical activity is high, low containing ash content, aluminium is low, phosphorus is low, sulphur is low become one kind not
Alternative carbon material.Semi-coke can replace coke and be widely used in the industries such as chemical industry, smelting, gas making.And it is blue in the present invention
The addition of charcoal can adsorb peculiar smell, prevent the diffusion of pernicious gas and peculiar smell.
It further, further include 0.1-1 parts and composite Portland cement 0.02-0.08 parts of forming agent.
Further, the forming agent is one kind or mixture of bentonite, clay or white carbon black.
Bentonite have very strong hygroscopicity and dilatancy, the water of adsorbable 8-15 times of own vol, in an aqueous medium
It can be dispersed into as a form of gel and suspension, this medium solution has certain viscosity, thixotropy and lubricity, there is stronger sun
Ion-exchange capacity has certain adsorption capacity to various gases, liquid, organic substance.
Composite Portland cement is as Portland clinker, mixing material as defined in two or more, appropriate stone
Hydraulic cementing materials made of cream is levigate, referred to as composite Portland cement.The addition of composite Portland cement can in the present invention
To enhance the intensity of product, reduce calorific value, is formed and balanced with the danger wastes of high heating value.
It further, further include 0.1-0.5 parts and waste emulsified mixture 1-3 parts of oxidation accelerator.
Further, the oxidation accelerator are as follows: hydrogen peroxide or peracetic acid.
Volatile stink or peculiar smell small molecule can be oxidized to nothing by the addition of oxidation accelerator, oxidation accelerator of the present invention
It small molecule or eliminates to peculiar smell, to use.It is peroxide, such as hydrogen peroxide, and peracetic acid waited oxygen organic.
Waste emulsified mixture is the hydrous waste object for referring to the oil emulsion for losing effect, is mainly derived from field of machining and disappears
Grinding's cooling liquid, wherein the by-product etc. containing decomposed metamorphic in organic matter class surfactant and use, complicated component, are relatively more steady
Fixed opaque coloured viscous liquid.Mainly using organic matter therein there are the characteristics such as calorific value, emulsification to replace original work
Industry emulsifier raw material reduces cost, the treatment of wastes with processes of wastes against one another.
A kind of preparation method of the industrial shaping coal using danger wastes production, comprising the following steps:
(1) danger wastes, coal dust, semi-coke, forming agent and composite Portland cement are respectively crushed into powder；
(2) powder obtained by step (1) is mixed evenly with water, extrusion granulation obtains graininess industrial shaping coal.
Graininess industrial shaping coal produced by the present invention is mainly used as the kiln of boiler, smelting and mineral processing, is using institute
It can be made to complete burning as far as possible when the industrial shaping coal stated, the exhaust gas main component for generation of burning is carbon dioxide, and burns and generate
Exhaust gas be easier to handle, it is substantially pollution-free to environment.
Further, in step (1), the fineness of gained powder is 60-100 mesh.
A kind of preparation method of the industrial shaping coal using danger wastes production, comprising the following steps:
A, danger wastes, coal dust, semi-coke are respectively crushed into powder；
