污泥干化焚烧装置

结构和原理

   为了zui大限度地提高传热速度和搅拌及摇动的效果，将干燥机的圆盘设计成中空倾斜盘。

   盘上装有自清洗装置，通过让圆盘旋转来刮下附着在圆盘旋转轴和外壳上的污泥。

   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.

特点

① 节能：采用间接加热方式，热效率高。

② 小型：间接加热方式，每单位面积的传热面积比直接加热干燥机大，所需占地面积较小。

③ 排气量少：间接加热方式，需要灌入的载气量较少，排气量也少。

④ 滤水含水量可调：通过 蒸汽流量或挡板来调节停留时间，控制含水率。

⑤ 高度干燥性能：由于投入的污泥在倾斜圆盘传热面上得到破碎和搅拌,在传热面上自行进行清洁，以便维持较高的传热系数。（蒸发系数：约8-20kg蒸气/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)  

污泥焚烧装置

结构和原理

  钢板制成的圆筒外壳中使用了耐火材料，内部也贴有绝热材料，形成耐火结构。流化床中插入分散管，通过分散管供应燃烧用空气形成流化层。

    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.       

特点

■ 完全燃烧：在高温的流化层内进行干燥和焚烧，可实现完全燃烧。

■ 理想形状：流化层部分为圆形，可维持高效的流动状态。

■ 可将残渣和沉砂进行混合燃烧：可将处理厂排出的残渣、沉砂和脱水滤饼一起进行混合燃烧。

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.
