Description
Technical field
The invention belongs in chemical products charcoal and its compound field, in particular to it is a kind of manufactured with anthracite it is nitrogenous
Active carbon and its manufacturing method.
Background technique
It is each that the active carbon adsorbent excellent as one kind is widely used in each row such as chemical industry, food, medicine, environmental protection
Industry.It is increasing to the demand of active carbon both at home and abroad with world industry development and the deep progress to enviromental protection and improvement.
The country manufactures nitrogenous active carbon with anthracite at present, the process generallyd use are as follows:
1. coal dust is made in anthracite；
2. by coal dust, coal tar (binder), the stirring of a small amount of water, mediating, glazing beads molding；
3. molding mass is carbonized；
4. Slapple activating furnace is added in carbonized material, activated using high-temperature water vapor activation method；
5. the active carbon after activation is crushed, it is sieved into nitrogenous active carbon.
" by the method for coal manufacture granular active carbon " (publication number GK87100558) as disclosed in Patent Office of the People's Republic of China 87 years,
The main points of this method are: taking 10 parts of weight coal dusts to add 4.5-8 parts of heat adhesives and appropriate hot water is added to mix and stir molding, mix and stir and contain in material
3.6-5.2 parts of asphalitine, material after molding bakes hard processing 1-4 hours at 200-440 DEG C, then carbonizes at 450-600 DEG C
Processing then carries out pickling processes to iron-content and is lower than 0.2%, is activated after washing, drying.
The above-mentioned method with anthracite production active carbon has the following problems:
1. production technology is complicated, manufacture product process spends the time long；
2. large scale equipment needed for producing is more, investment is big；
3. contamination phenomenon is serious in production process, coal dust process contamination production environment such as processed, and unfavorable to producer's health.
Coal tar, pitch etc. is added to pollute active carbon itself, applies activated carbon product by limitation (as eaten
Product, medical and health industry cannot use, and the processing of drinking water is restricted).
Summary of the invention
The purpose of the present invention is the shortcomings for existing product and production technology, provide a kind of manufactured with anthracite and contain
The active carbon and its manufacturing method of nitrogen.
The technical solution of the present invention is as follows: using anthracite for raw material, without powder processed, molding procedure, anthracite is broken into
Grain particles (particle size range 1-8mm) required by product pass through high-temperature water vapor (temperature 850-980 in activation furnace
DEG C) activated obtained activated carbon product.Activation section of the raw material in furnace is 50-80 hours by the time.It is obtained nitrogenous
Active carbon can reach following technical indicator: iodine sorption value 800-1100mg/g, Penetrating curve 50-80%, and serge blue takes off
Color power 120-220mg/g, intensity 90-100%, as water purification charcoal without floating.
The present invention has the advantage that
1. greatly shortening, simplifying process route, reduce investment of founding the factory, save the energy, low production cost.
2. avoiding the environmental pollution in production due to eliminating coal dust process processed；
3. avoiding product resulting from due to being added without the substances such as coal tar, pitch in production process of activated carbon
The pollution of itself expands the application range of active carbon.
