Problems solved by technology

Rotary kiln incinerators have more rotating parts and slightly more maintenance. They have high mechanical technical requirements, low thermal efficiency, and higher technical conditions than pyrolysis incinerators. The dust concentration in the flue gas is high, accompanied by thermal NOx, especially Crude oil in oily sludge cannot be recycled and cannot meet the large-scale treatment capacity
The chain plate conveyor belt cracking furnace has sludge residues falling off when the chain plate goes down, and the lower cylinder wall is easy to coke, which will cause local overheating of the

Example Embodiment

[0036] The present invention will be further described below in conjunction with the accompanying drawings. Of course, the following embodiments should not be construed as limiting the present invention.

[0037] Such as figure 1 As shown, the present invention is a continuous pyrolysis treatment system and process for oily sludge, including 1-feed pre-sorting unit, 2-drying pyrolysis unit, 3-dust removal and condensation unit, and 4-discharge processing unit;

[0038] Such as figure 2 As shown, the feed pre-sorting unit 1 includes a feeding screw conveyor 11, a vibrating machine 12, a centrifuge 13, a mud pump 14, a heating boiler 15, an oil and water storage tank 16, a chemical dosing machine 17 and a mud collecting tank 18. First, the primary selection is carried out. The oily sludge is sent to the sludge mixing tank by the feeding screw conveyor for dilution and heating, and then pumped into the drum screening device for rough screening, and the solid sand and gravel larger tha...

Abstract

The invention belongs to the field of waste disposal in petroleum industry, and relates to an industrialization scale pyrolysis treatment system for oily sludge. The industrialization scale pyrolysis treatment system comprises a feeding pre-separation unit for performing secondary screening and solid-liquid separation on the oily sludge, a drying pyrolysis unit for performing drying and pyrolysis reaction on the oily sludge, a dust removal and condensation unit for performing dust removal and condensation on a pyrolysis gas mixture generated by the drying pyrolysis unit, and a discharge treatment unit which receives and treats separated substances of the other units respectively. Solid or solid-liquid mixed waste such as the oily sludge can be finally treated to achieve reduction, stabilization, harmlessness and recycling.

Description

technical field [0001] The invention belongs to the field of waste treatment in the petroleum industry, and relates to an oily sludge treatment system and method, in particular to a large-scale pyrolysis treatment system and method for oily sludge. Background technique [0002] Oily sludge is a kind of solid-liquid mixed waste rich in mineral oil (especially HW08 waste mineral oil) produced in the process of petroleum exploration, mining, storage, transportation and refining. Generally speaking, oily sludge Its appearance is black and viscous, and the oil-in-water, water-in-oil and suspended solid impurities are fully emulsified with each other to form a very stable suspension emulsion system. The longer the storage time, the more difficult it is to handle. Oily sludge is a highly dangerous pollutant, and many countries list it as a highly dangerous pollutant and give priority to controlling hazardous pollutants. [0003] At present, the treatment methods of oily sludge inc...
