摘要
活性炭是一種無毒無味,具有發(fā)達(dá)細(xì)孔結(jié)構(gòu)和巨大比表面積的優(yōu)良吸附劑。因此,活性炭可以重新恢復(fù)吸附活性,重復(fù)使用,具有重要的意義。活性炭再生爐的功能是除去吸附的雜質(zhì),使活性炭重新恢復(fù)吸附活性。
國內(nèi)活性炭再生設(shè)備隨著市場的需求向能耗低、效率高、活性炭損失少、再生效果好、性能參數(shù)可調(diào)、自動化程度高、規(guī)格種類較齊全的方向發(fā)展。直熱式活性炭再生爐的主要組成有再生爐體、進(jìn)料裝置、出料裝置、支架和輔助機(jī)構(gòu)等。進(jìn)料裝置和出料裝置的核心機(jī)構(gòu)都是螺旋輸送機(jī)。它控制著進(jìn)料和出料的速度。由于本設(shè)計(jì)的難題之一是協(xié)調(diào)進(jìn)料的速度和出料的速度兩者之間的關(guān)系,而由兩個(gè)同種型號的螺旋輸送機(jī)控制速度就為解決這個(gè)問題提供了很大的方便?;钚蕴扛邷?zé)嵩偕椒ㄊ峭ㄟ^加熱對活性炭進(jìn)行熱處理,使活性炭吸附的有機(jī)物在高溫下活性炭化分解,最終成為氣體逸出,從而使活性炭得到再生。高溫加熱再生在除去活性炭吸附有機(jī)物的同時(shí),還可以除去沉積在活性炭表面的無機(jī)鹽,而且使活性炭的新微孔生成,使活性炭的活性得到根本的恢復(fù)。直熱式是利用活性炭的導(dǎo)電性和電阻性直接對活性炭進(jìn)行加熱升溫,使雜質(zhì)進(jìn)行脫附。
本次設(shè)計(jì)主要是使活化前的活性炭能通過螺旋輸送裝置和料槽按既定的速度進(jìn)入爐體,爐體通過支架能夠固定和易于拆裝和活化后的活性炭通過葉片均勻的進(jìn)入冷卻裝置。

ABSTRACT
Activated carbon is a kind of non-toxic tasteless which has developed pore structure and huge specific surface area of the adsorbent. Therefore,It has the vital significance that makes the charcoal adsorption activity again. The function of activated carbon regeneration furnace is removal of adsorbed impurities that restores charcoal to adsorption activity.
Domestic activated carbon regeneration equipments along with the market demand to low energy consumption, high efficiency, less loss of activated carbon, regeneration effect is good, the performance parameters are adjustable, high degree of automation, specifications varieties complete.
Direct heat activated carbon regeneration furnace is made of regenerative furnace, feeding device, discharge device, support and auxiliary mechanism, etc. It is the core of the Feeding device and discharging device that is a screw conveyor. It controls the speed of the feeding and discharging. Because this design is one of the problems of coordination of feed speed and discharge rate, the relationship between the two by two of the same type of screw conveyor speed control provides a great convenience to solve the problem. High-temperature heat activated carbon regeneration method is by heating to heat treatment of activated carbon, activated carbon adsorption of organic compounds in high temperature carbonization decomposition, finally become gas escape, so that the regeneration of activated carbon. High temperature heating regeneration in the removal of carbon adsorption of organic compounds at the same time, also can remove deposition on the surface of the carbon, inorganic salt, and makes new microporous carbon generation, on the activity of carbon is fundamental recovery. Direct heat is to use activated carbon conductive and resistive to heat activated carbon directly to heat up, make the impurities for stripping.
This design mainly is to make before activation of activated carbon can through the screw conveyer and the discharge chute according to set speed into the furnace, the furnace can be fixed by stent and easy to tear open outfit and activation of activated carbon by blade evenly into the cooling unit.
KEY WORDS: activated carbon regeneration regeneration furnace directly-heated type
