結構和原理
為了zui大限度地提高傳熱速度和攪拌及搖動的效果,將干燥機的圓盤設計成中空傾斜盤。
盤上裝有自清洗裝置,通過讓圓盤旋轉來刮下附著在圓盤旋轉軸和外殼上的污泥。
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:通過 蒸汽流量或擋板來調節(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
結構和原理
鋼板制成的圓筒外殼中使用了耐火材料,內部也貼有絕熱材料,形成耐火結構。流化床中插入分散管,通過分散管供應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:在高溫的流化層內進行干燥和焚燒,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.
