Abstract

The invention discloses mud-sand separation and oil sludge dehydration and drying treatment equipment and a treatment process, the treatment equipment comprises a submersible sand excavation pump, a sand washing tank, a submersible pump, a cyclone, a dehydrator and a drying machine, and the treatment process comprises the following steps: (1) pumping oil sludge from an oil sludge pool to the sand washing tank by using the submersible sand excavation pump; (2) starting a stirring paddle in the sand washing tank, adding hot water while stirring, and fully mixing the hot water with the oil sludge; (3) pumping the oil sludge water into a hydrocyclone by a submersible pump, discharging sand, and upwards discharging the oil sludge water from an overflow port to enter a dehydrator; (4) concentrating and dehydrating in a dehydrator to obtain wet mud; and (5) drying the wet sludge in a drying machine to obtain dried sludge. According to the mud-sand separation and oil sludge dewatering and drying treatment equipment and the treatment process, sand in the oil sludge is separated from sludge, on one hand, the sand can be recycled, and energy conservation and environmental protection are achieved; on the other hand, subsequent sludge treatment is facilitated, the treatment efficiency of the oil sludge is improved, and the finally obtained dried sludge is low in water content and oil content.

Description

technical field [0001] The invention belongs to the technical field of oil sludge treatment, and in particular relates to equipment and a treatment process for sludge separation and oil sludge dehydration and drying. Background technique [0002] Sludge is oily sludge produced in the process of oil exploitation, which contains not only petroleum components, but also water, sand and gravel. Therefore, it has the characteristics of high oil content, high viscosity, many harmful components and large volume. If left unattended, it will pollute the soil, groundwater and air. [0003] At present, the treatment of oily sludge at home and abroad usually adopts stacking, landfill, incineration, solidification and other treatment methods, but these methods have low processing capacity, high energy consumption, high cost, long cycle, poor effect, and will produce different degrees of secondary pollution. secondary pollution, and it is not conducive to resource reuse; pyrolysis method ...
