The present invention adopts following technical scheme to realize:
A preparation method for water purification granulated active carbon, comprises the steps:
(1), abrasive dust: bituminous coal is put into pulverizing mill and carry out abrasive dust, granularity requirements 325 order 80% passes through;
(2), mixing: the pulverized-coal distribution of milled oil, water are mixed with the part by weight of 80:12:8, mixing temperature is 35 DEG C ~ 60 DEG C;
(3), granulation: added by compound in tablets press and carry out granulation, tablets press operating frequency is 30Hz, and granulation material diameter is 9.0 ~ 10.0mm;
(4), dry: granulation material carries out drying in drying machine, and drying temperature is 90 DEG C ~ 110 DEG C;
(5), carbonize: dried feed is added converter and carbonizes, temperature is 600 DEG C ~ 650 DEG C, and discharging time is 30min;
(6), broken: particulate state carbonized material being crushed to 3-8mm.
(7), activate: the carbonized material broken is added Slapple activating furnace and activates, temperature is 880 DEG C ~ 960 DEG C, and discharging time is 60h;
(8), screening packaging: activated material is crushed to 8-30 object granular active carbon and packs.
Compared with prior art, the inventive method advantage specific as follows:
1, use bituminous coal to replace hard coal can save a large amount of expensive hard coal, reduce production cost.
2, gained gac intensity is good, has good adsorptive power.
3, the atmospheric pollution in worker-house is decreased.
4, gained gac may be used for the industries such as water treatment, decolouring, taste removal.
The inventive method is reasonable in design, produces the water purification charcoal product meeting market demands with less coal, granulating and forming.Under the prerequisite reducing production cost and environmental pollution, the granulated active carbon produced by this method is respond well in sewage disposal.
