【概要描述】对于炼化三泥处理,开发了污油泥处理技术设备,其工艺流程主要如下:
冲砂废水通过进料管进入高效节能固液分离一体机,进料管由自动沉降装置和离心分离装置组成。通过自然沉降,上清液流入回收罐,沉降后的泥浆进入离心分离装置进行进一步的固液分离。该污油泥处理技术设备可连续运行24小时,不仅提高了分离效率,而且节约了能源消耗,使处理后的洗沙废水清水可以回用。



For the treatment of three sludges in refining and chemical process, the technical equipment of sludge treatment has been developed, and the process flow is mainly as follows:
Sand washing wastewater enters the high efficiency and energy saving solid-liquid separation machine through the feed pipe, which is composed of automatic settling device and centrifugal separation device.
Through natural settlement, the supernatant flows into the recovery tank, and the settled mud enters the centrifugal separation unit for further solid-liquid separation.
The sewage sludge treatment technology equipment can run continuously for 24 hours, which not only improves the separation efficiency, but also saves energy consumption, so that the treated sand washing wastewater and water can be reused.

对于炼化三泥处理,开发了污油泥处理技术设备,其工艺流程主要如下:

For the treatment of the three sludges in refining and chemical process, the technical equipment of sludge treatment has been developed, and the process flow is mainly as follows:

 


冲砂废水通过进料管进入高效节能固液分离一体机,进料管由自动沉降装置和离心分离装置组成。通过自然沉降,上清液流入回收罐,沉降后的泥浆进入离心分离装置进行进一步的固液分离。该污油泥处理技术设备可连续运行24小时,不仅提高了分离效率,而且节约了能源消耗,使处理后的洗沙废水清水可以回用。

Sand washing wastewater enters the high efficiency and energy saving solid-liquid separation machine through the feed pipe, which is composed of automatic settling device and centrifugal separation device. Through natural settlement, the supernatant flows into the recovery tank, and the settled mud enters the centrifugal separation unit for further solid-liquid separation. The sewage sludge treatment technology equipment can run continuously for 24 hours, which not only improves the separation efficiency, but also saves energy consumption, so that the treated sand washing wastewater and water can be reused.

 


自动进料:采用专门设计的斗式污泥提升功能,输送液体、固体和半固体含油污泥,直接将含油污泥从污泥池送至移动式预处理装置,满足连续进料。此外,斗式提升机进料口设有一级除杂网槽,可防止丝带、木棒等大杂质进入加工系统。

Automatic feeding: the specially designed bucket sludge lifting function is adopted to transport liquid, solid and semi-solid oily sludge and directly send oily sludge from sludge tank to mobile pretreatment device to meet continuous feeding. In addition, the bucket elevator feed port is provided with a level of miscellaneous net slot,  it can prevent large impurities such as ribbon, wood rod into the processing system.

 


炼化三泥处理处理:预处理装置入口处的含油污泥由污泥分选轮和筛板驱动,聚集在一起的污泥通过污泥分选轮的旋转而分散。污泥中大于20毫米的颗粒被分选轮推入预处理装置一侧的大料收集箱,小于20毫米的污泥通过污泥分选筛板的筛孔进入污泥预处理池。通过含油污泥分离轮和筛板的共同作用,实现含油污泥的除杂、纤维粉碎、均匀分散、油浆储存和输送。

Refining and three sludge treatment: the oil-bearing sludge at the inlet of the pretreatment device is driven by the sludge sorting wheel and the sieve plate, and the aggregated sludge is dispersed by the rotation of the sludge sorting wheel. Particles larger than 20 mm in the sludge are pushed into the aniseed collection box at one side of the pretreatment device by the sorting wheel, while the sludge less than 20 mm enters the sludge pretreatment tank through the sieve holes of the sludge separation screen plate. Through the joint action of oil-bearing sludge separation wheel and sieve plate, the oil-bearing sludge can be removed impurity, fiber crushing, evenly dispersed, oil slurry storage and transportation.

 


清洗:在含油污泥一级、二级、三级清洗装置中完成。通过化学药剂、超声波、气浮和搅拌的作用,实现了油泥的流化、清洗和游离原油的脱除。

Cleaning: it is completed in the first, second and third cleaning equipment of oily sludge. Fluidization, cleaning and free crude oil removal are realized by chemical agents, ultrasonic wave, air flotation and stirring.

 


污油泥处理技术设备固液分离:利用高效节能的固液分离器实现固体污泥与液体的分离。

Solid - liquid separation: the solid - liquid separator with high efficiency and energy saving is used to realize the separation of solid sludge and liquid.

 


油水处理:三级清洗装置收集的浮油输送到油箱,从油箱沉淀出来的水输送到水箱。高效节能固液分离器分离出的液体进入水箱,水箱中的浮油可以收集并输入油箱,热水可以作为循环水重复使用。

Oil and water treatment: the oil slick collected by the three-stage cleaning device is transported to the tank, and the water deposited from the tank is transported to the tank. The liquid separated by the efficient and energy-saving solid-liquid separator enters the tank, where the oil slick can be collected and fed into the tank, and the hot water can be reused as circulating water.
