A modular skid-mounted system and method for treating oily sludge with low-temperature ion method

Abstract

The invention discloses a modularized skid-mounted system for low temperature ion process treatment of oil-containing sludge, and a method thereof. The system comprises a particle size sorting module, a solid-liquid individual conveying module, a liquid phase mixed material cleaning module, a primary crude oil separation module, a secondary crude oil separation module, a primary solid-liquid separation module, a secondary solid-liquid separation module, a crude oil storage module, a circulating water storage module, a circulating water heating module, a flue gas reuse module and a medicament application module, and every above module has a skid-mounted structure. The oil-containing treatment method comprises the following steps: oil-containing sludge sequentially goes through the particle size sorting module, the solid-liquid individual conveying module, the liquid phase mixed material cleaning module, the primary crude oil separation module, the secondary crude oil separation module, the primary solid-liquid separation module and the secondary solid-liquid separation module; the crude oil storage module receives crude oil output by the primary crude oil separation module and the secondary crude oil separation module; the circulating water storage module stores and outputs circulating water; the circulating water heating module heats the circulating water; the flue gas reuse module receives flue gas output by the circulating water heating module; and the medicament application module outputs a medicament.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a modularized skid-mounted system and method for treating oily sludge with a low-temperature ion method. Background technique [0002] Oily sludge is a mixture of various forms of crude oil or refined oil mixed with soil or other media. The oil in it cannot be directly recovered and may cause pollution. It is one of the main pollutants in the petrochemical industry. The sources of oily sludge mainly include the following ways: oily sludge produced in crude oil extraction, oily sludge produced in the process of oilfield gathering and transportation, and oily sludge produced in refinery sewage treatment, especially in crude oil production. The oily sludge is also mixed with a large amount of inclusions such as plastic cloth, stones, ironware and wood. At present, sludge storage pits are often used to store a large amount of oily sludge. Accord...

Problems solved by technology

[0015] Using thermochemical method to treat oily sludge, thermochemical agents are the key, but the current types of thermochemical agents are still relatively single, and their compatibility is poor, and thermochemical methods have strict requirements on temperature, due to the oil in oily sludge The nature of the species is quite different, and the applicable thermochemical treatment temperature is also different, so the standard after treatment is low, and it cannot meet the requirements of industrial treatment.
