Description
Technical field
The present invention relates to the preparation field of absorbent charcoal material, a kind of Ginkgo Leaf prepares the method for medical activated carbon fast specifically.
Background technology
The active carbon from coal annual production of current China only has about 300,000 t, is far not enough to demand and the demand for exports of satisfied following domestic gac, estimates that the gac annual production of the year two thousand twenty China needs to reach the demand that about 500,000 t could meet global gac market.Active carbon from coal is still the main source in China's gac market, but he be subject to coal, production technique restriction added value lower.The biological raw materials such as nutshell were utilized to prepare the existing a lot of research of method of gac in recent years.But the ownership system is for the technological method of gac at present, all be unable to do without protection of inert gas high temperature (600 ~ 700 DEG C) and carbonizes this link, have larger power consumption, the deficiencies such as complex manufacturing, cycle length.In addition along with the carrying out of city, township's greening work, ginkgo cultivated area expanding day, a large amount of Ginkgo Leaves has become new town and country rubbish, for the utilization of waste material of Ginkgo Leaf, requires study.
Summary of the invention
For solving the technical problem of above-mentioned existence, the invention provides a kind of method that Ginkgo Leaf prepares medical activated carbon fast, utilize the method for low temperature flash carbonization, do not need high temperature just can realize carbonization, reduce energy consumption, improve the security in production process, reduce production cost, constant product quality, has wide application prospect.
For achieving the above object, the technical solution adopted in the present invention is:
Utilize Ginkgo Leaf to prepare a method for medical activated carbon fast, realize as follows:
(1) choose Ginkgo Leaf removal of impurities, at 100-120 DEG C of dry 30-50min, be crushed to 50-80 mesh sieve;
(2) be put in furnace pot by Ginkgo Leaf fine powder, feeding intake in the ratio of Ginkgo Leaf fine powder and vitriol oil mass ratio 1:0.8-1.2 fully mixes;
(3) by step 2) batch mixing in furnace pot is put in direct heating in control-temperature electric heating cover and tentatively carbonizes, and then controls at 260-320 DEG C by temperature, through 30-90min time carbonization;
(4) after being prepared by step 3) material cooling, with tap water to neutral suction filtration, dry gac is obtained at the dry 40-80min of 110-150 DEG C of temperature;
(5) by the gac micronizing of drying, in 240-280 DEG C of temperature-activated 60-120min, point grade packaged both product;
(6) waste gas, waste liquid are directly imported in saturated limewater pond reach purification.
The present invention has broken traditional preparation mode, take the method for Ginkgo Leaf being carried out direct low temperature flash carbonization, technique is simple, temperature is low, and security is good, only relates to a kind of reagent of the vitriol oil, waste gas, waste liquid are directly passed in saturated limewater and just can be purified, cost is low pollution-free, and the gac purity of preparation is high, good dispersity, high adsorption capacity in water, iodine Xi Fu Zhi≤800mg/g.
