Oil sludge cleaning and processing system for oil tank

Abstract

The invention discloses an oil sludge cleaning and processing system for an oil tank. The oil sludge cleaning and processing system comprises a cleaning system, an oil sludge processing system and an integrated control system, wherein the cleaning system comprises a cleaning robot, an electric hydraulic pump, a water pump, an inert gas storage tank and a screw pump; the cleaning robot comprises a machine body, a traveling unit, a cleaning unit, a robot cleaning control unit, a sensing and communication unit and a robot power supply unit; the oil sludge processing system comprises an oil sludge processing device, an oil sludge processing control system and an oil sludge processing power supply device; the oil sludge processing device comprises a stirring machine, an ultrasonic emulsion breaking device, a centrifuge and an ultrafiltration system, as well as an oil sludge storage pool, a sludge pool, a centrifugal liquid storage tank, a concentration tank and a filtrate pool; a funnel is arranged on the stirring machine; and the integrated control system comprises an integrated control computer and a communication circuit module. The oil sludge cleaning and processing system disclosed by the invention has the advantages of reasonable design and high degree of intelligentization, and can realize comprehensive cleaning of the oil tank, good safety, fast oil sludge processing speed and resource utilization of oil sludge, and further reduce environmental pollution and waste of resources.

Description

technical field [0001] The invention relates to the technical field of oil sludge cleaning and treatment, in particular to an oil tank oil sludge cleaning and treatment system. Background technique [0002] In my country's petrochemical industry, for crude oil storage equipment such as oil storage tanks and oil trucks, due to the difficulty in guaranteeing the quality of oil products, an average of 800,000 tons of tank bottom sludge and pool bottom sludge are produced every year. Oily sludge is a large and wide-ranging pollution source, containing pathogenic bacteria, parasites (eggs), heavy metals, salts, polychlorinated biphenyls, dioxins, radionuclides and other refractory toxic and harmful substances. A large amount of oily sludge is produced, and the potential impact on the environment is increasing. The sludge produced has been included in the "National Hazardous Waste Catalog" as oily waste. Since oily sludge is a hazardous waste, random discharge or simple stacking ...

AI Technical Summary

Problems solved by technology

Commonly used equipment for oil sludge treatment includes dehydration devices, filtration devices, pressurization devices, incineration devices, etc., most of which have certain problems. Some equipment has relatively low production efficiency, and some equipment produces dross that is difficult to handle. Relatively big difficulty

For example, Daqing Oilfield imported a set of oily sludge treatment equipment from the UK, but the utilization rate has been very low since the purchase for 6 years; in addition, the whole set of equipment is expensive (only one 15m 3 The price of a centrifuge with a processing capacity per hour is as high as 150,000 euros), and this equipment has not been promoted and used in China
