Abstract

The invention discloses oily sludge dehydration processing equipment and a method thereof, and relates to the processing technology of oily sludge processing. The oily sludge dehydration processing equipment comprises a prying base, a conveying pump, a Venturi device, a feed screw, a first conditioning reaction tank, a circulation pump, an ozone ejector, a static state mixing device, an ozone strength control tank, a second conditioning reaction tank, a blower, a screw pump, a screw pressure dehydrator, an ozone device, a 2# flocculant adjusting tank and a NaOH adjusting tank. The oily sludge dehydration processing equipment is simple in technology and capable of well solving the dehydration problem of the oily sludge of an oil field, and innovatively adopts the ozone dehydration stabilization technology, medicament is not needed and no secondary pollution exists; the device adopted by the oily sludge dehydration processing equipment is a fully integrated automatic prying device, and the oily sludge dehydration processing equipment is small in ground-drilling area and high in automation degree, and the investment cost and operation cost of the oily sludge dehydration processing equipment are both lower than those of traditional processing equipment.

Description

technical field [0001] The invention relates to oily sludge treatment technology, in particular to oily sludge dehydration treatment equipment and a method thereof. Background technique [0002] During the treatment of oilfield sewage, a large amount of oily sludge is associated with it, which is in the form of black viscous slurry. Stacking in the open air or burying in pits not only pollutes soil, air and groundwater sources, endangers the environment and the health of residents, but also poses safety hazards such as inducing combustion and explosion. The pollution-free treatment of oily sludge has become the focus of research in recent years. If it is not handled properly, it will cause serious environmental pollution problems, and organic pollutants have a high toxic effect on the human body and the environment, and it has gradually attracted people's attention. Oily sludge has been listed as waste mineral oil in the National Catalog of Hazardous Wastes, and oily sludge...
