Problems solved by technology

Since the application of ultrasonic waves in the treatment of petroleum pollutants, a large number of related treatment technologies have been developed. However, although most of the related technologies have better treatment effects, the oil removal rate can only be reduced to a certain extent and cannot be completely removed. Once removed, it cannot be used again

Abstract

The invention provides an oil removal system which comprises a primary ultrasonic treatment system, an ultrafiltration membrane device, a secondary thermal distillation treatment system and a water circulation system, the primary ultrasonic treatment system comprises an ultrasonic reaction chamber and a standing tank, the secondary thermal distillation treatment system comprises a reaction kettle, a condenser and an oil storage tank, and the water circulation system comprises a reservoir; a second inlet of the ultrasonic reaction chamber is connected with the reservoir, an outlet of the ultrasonic reaction chamber is connected to an inlet of the standing tank, floating oil collectors are arranged in the ultrasonic reaction chamber and the standing tank respectively, and an outlet of the standing tank is connected to the ultrafiltration membrane device; a first outlet of the ultrafiltration membrane device is connected to the reservoir, and a second outlet of the ultrafiltration membrane device is connected to an inlet of the reaction kettle; a first outlet of the reaction kettle is connected to an inlet of the condenser, and a first outlet of the condenser is connected to an inlet of the oil storage tank. The oil removal effect of the oil-containing silt is improved, the working efficiency is improved, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of deoiling treatment and recovery of oily wastewater and oily solid waste, in particular to an oil removal system. Background technique [0002] With the gradual intensification of the pollution impact of petroleum pollutants, the pollution has become a serious ecological and environmental problem worldwide. Oil and its products are prone to overflow and leakage due to various reasons during exploration, transportation and use, causing them to enter the soil or sand and cause serious oil pollution. Drainage or sanitary landfill may cause petroleum hydrocarbon pollutants to enter the atmosphere, water and soil environment. Many toxic components in petroleum hydrocarbon pollutants have direct or potential threats to human health and the environment, and must be effectively removed. [0003] At present, there are many degreasing technologies. Among them, ultrasonic technology has the characteristics of simpl...
