結(jié)構(gòu)和原理
為了zui大限度地提高傳熱速度和攪拌及搖動的效果，將干燥機的圓盤設(shè)計成中空傾斜盤。
盤上裝有自清洗裝置，通過讓圓盤旋轉(zhuǎn)來刮下附著在圓盤旋轉(zhuǎn)軸和外殼上的污泥。
The disk of dryer is designed as hollow inclined tray for increasing heat transfer rate and effect of churn maximatily.
There are self-cleaning devices on the disk, scraping sludge attaching on rotating axis and casing through tray rotating.
特點
① 節(jié)能：采用間接加熱方式，熱效率高。
② 小型：間接加熱方式，每單位面積的傳熱面積比直接加熱干燥機大，所需占地面積較小。
③ 排氣量少：間接加熱方式，需要灌入的載氣量較少，排氣量也少。
④ 濾水含水量可調(diào)：通過 蒸汽流量或擋板來調(diào)節(jié)停留時間，控制含水率。
⑤ 高度干燥性能：由于投入的污泥在傾斜圓盤傳熱面上得到破碎和攪拌,在傳熱面上自行進(jìn)行清潔，以便維持較高的傳熱系數(shù)。（蒸發(fā)系數(shù)：約8-20kg蒸氣/m2hr）
① Energy saving: indirect heating, high thermal efficiency
② Minitype: indirect heating, large heat transfer area, small floor area
③ Less displacement: indirect heating with less injection supporting gas.
④ Adjustable filtered water containing moisture: adjust detention time through steam flow or damper, water ratio shall be controlled.
⑤ High dry performance : the mud on the heat transfer surface of slantwise dial can receive smash and stir, thus self-clean itself to maintain high heat transfer factor.(factor of evaporation: about 8-20kg/m2hr)
污泥焚燒裝置
結(jié)構(gòu)和原理
鋼板制成的圓筒外殼中使用了耐火材料，內(nèi)部也貼有絕熱材料，形成耐火結(jié)構(gòu)。流化床中插入分散管，通過分散管供應(yīng)燃燒用空氣形成流化層。
The steel cylindrical casings using fire proof material,also heat insulating material interiorly, which forms fire-proof structure. With the Scattered tube inserted in fluid bed , it can supply the air used for incineration to generate fluosolids.
特點
■ *燃燒：在高溫的流化層內(nèi)進(jìn)行干燥和焚燒，可實現(xiàn)*燃燒。
■ 理想形狀：流化層部分為圓形，可維持高效的流動狀態(tài)。
■ 可將殘渣和沉砂進(jìn)行混合燃燒：可將處理廠排出的殘渣、沉砂和脫水濾餅一起進(jìn)行混合燃燒。
Perfect combustion: drying and incineration in high temperature fluosolids.
Ideal form: part of fluosolids is in circular form, maintaining high efficient flow.
Mixed incineration of residue and grit:conduct the combined incineration for the effluent residue , grit and dehydrated filter mass.
