Process and system for treating oily sludge
The invention relates to the technical field of environmental protection, in particular to a process and a system for treating oily sludge. The invention provides a process for treating oily sludge, which is realized by the following steps of: a, drying and dehydrating the oily sludge, crushing to obtain dried oily sludge, and mixing the dried oily sludge with a desulfurization and denitrification additive to obtain a mixture; B, putting the mixture into a circulating fluidized bed incinerator to be incinerated, and obtaining ash residues; and c, introducing high-temperature flue gas generated by incineration into a preheating recovery boiler to recover heat, then conducting dust removal, and obtaining clean flue gas with nitrogen and sulfur removed. The oily sludge can be effectively treated, pollution to the atmosphere after incineration treatment of the oily sludge is reduced, and clean and efficient combustion of the oily sludge is achieved.
本发明涉及环保技术领域，更具体地说，涉及一种用于处理含油污泥的工艺及系统。本发明提供了一种用于处理含油污泥的工艺，该工艺通过以下步骤实现：a.将含油污泥干化脱水后进行破碎，得到干化含油污泥，然后与脱硫脱氮添加剂混合，得到混合料；b.将所述混合料置入循环流化床焚烧炉进行焚烧，得到灰渣；c.将焚烧产生的高温烟气引入预热回收锅炉回收热量，然后进行除尘，得到脱除了氮和硫的清洁烟气。本发明可有效对含油污泥进行处理，降低含油污泥焚烧处理后对大气造成的污染，以实现含油污泥清洁、高效燃烧。
