要根據(jù)具體工藝目的結(jié)合兩種活性炭的各自優(yōu)點而選用。
粉狀活性炭通常在液相應(yīng)用,加入液體后經(jīng)攪拌混合、過濾或沉降,而得所要的液體。以粉狀活性炭處理的優(yōu)點是:適用于間歇工藝;易控制加入量;可利用現(xiàn)成過濾設(shè)備;價格較低。
粒狀活性炭可用于液相,也可用于氣相。一般將要處理的液體或氣體連續(xù)通過活性炭柱。以粒狀活性炭處理的特點是:適用于連續(xù)工藝與自動控制;較少活性炭耗量,使用的炭/液比高;較易清潔操作;因價較高大量使用時應(yīng)予再生,且較易再生。



活性炭是一種經(jīng)特殊處理的炭,將有機原料(果殼、煤、木材等)在隔絕空氣的條件下加熱,以減少非碳成分(此過程稱為炭化),然后與氣體反應(yīng),表面被侵蝕,產(chǎn)生孔發(fā)達的結(jié)構(gòu) (此過程稱為活化)。由于活化的過程是一個觀過程,即大量的分子碳化物表面侵蝕是點狀侵蝕 ,所以造成了活性炭表面具有無數(shù)細小孔隙?;钚蕴勘砻娴目字睆酱蠖嘣?~50nm之間,即使是少量的活性炭,也有巨大的表面積,每克活性炭的表面積為500~1500m2,活性炭的一切應(yīng)用,幾乎都基于活性炭的這一特點。


普邦環(huán)保材料(保定市分公司)坐落于我省經(jīng)濟實力和發(fā)展活力的腹地—河北保定,得天獨厚的地理優(yōu)勢,市場優(yōu)勢的地位,促使河北保定工業(yè)強勢發(fā)展;應(yīng) 碳酸氫鈉發(fā)展趨勢,我公司本著“用戶至上,勇于創(chuàng)新”的企業(yè)方針,發(fā)揚求真務(wù)實的開拓精神,不斷引進國內(nèi)外先進的 碳酸氫鈉技術(shù), 碳酸氫鈉產(chǎn)品性能已逐步同國際市場接軌,成功案例遍布全國20個省份。




The two is to look at the honeycomb activated carbon products produced by the bubble, if the bubble is more the better the quality of the product. We can do a little experiment, a handful of honeycomb activated carbon products into the water, because the water penetration effect, water will be immersed in the pores of activated carbon, so the pore in the air, resulting in a series of very small bubbles, pulled out a tiny bubbles lines in the water, at the same time also issued Zizi bubble sound, looked very interesting. If this phenomenon is very serious, and the longer the duration, then it is proved that the honeycomb activated carbon product pore structure is very developed, that is, the better adsorption performance of honeycomb activated carbon.
