概述
廢熱空氣或換熱空氣進(jìn)入轉(zhuǎn)筒干燥器內(nèi),在通道中直接與濕固廢傳熱傳質(zhì),配套專用破碎裝置(特殊結(jié)構(gòu)設(shè)計(jì)),使固廢中的水分快速蒸發(fā),固廢顆粒較小的隨氣體一起由外通道排出干燥器收集,而較大的固廢顆粒在干燥器中停留的時間較長,直至干化完成。部分廢氣抽出,經(jīng)除臭器處理達(dá)到大氣排放標(biāo)準(zhǔn)后(或經(jīng)水沫除塵降溫后)排入大氣中。
Waste hot air or heat exchange air enters the rotary drum dryer,and directly transfers heat and mass with wet solid waste in the channelA special crushing device (special structure design)is equipped to make the moisture in solid waste evaporate quickly.Smaller solid waste particles are discharged from the dryer with the gas and collected while larger solid waste particles stay in the dryer for a long time until drying is completed. Part of the waste gas is extracted treated by deodorizer and discharged into the atmosphere (or cooled by water foam dust removal).
特點(diǎn)
(1)根據(jù)固廢干化過程中的特性及狀態(tài),分段采用不同的分散破
碎裝置,大大提高干化效能。
(2)采用特殊密封材料,保證密封效果,且壽命大大提高。
(3)軸承采用冷卻裝置,降低軸承使用溫度,延長使用壽命;
(4)可采用間接加熱方式,減少排風(fēng)量及提高熱利用率:
(5)根據(jù)不同狀態(tài)的固廢采用不同抄板形式,降低粘結(jié)程度:
(6)根據(jù)固廢特性采用不同的進(jìn)料方式,以防止進(jìn)料堵塞。
(1) According to the characteristics and state of solid waste drying process,different dispersing and crushing devices are adopted in stages.
which greatly improves the drying efficiency.
(2) Special sealing materials are adopted to ensure the sealing effect and greatly improve the service life
(3) the bearing adopts a cooling device, which reduces the service temperature of the bearing and prolongs the service life
(4)indirect heating can be used to reduce the exhaust air volume and improve the heat utiization rate
(5) According to the different state of solid waste,different forms of paper making are adopted to reduce the bonding degree:
(6) According to the characteristics of solid wastedifferent feeding methods are adopted to prevent feeding blockage.
