Method for constructing sludge treatment system based on sludge component

Abstract

The invention relates to the field of oily sludge treatment and specifically relates to a method for constructing a sludge treatment system based on a sludge component. The method is suitable for the treatment of the sludge with the oil content from 5% to 50% and the water content from 0% to 85%. The method comprises the following steps: 1) dividing modules: dividing 9 modules according to a treatment process required by the sludge treatment under the above conditions, namely, a sorting impurity removing module, a materialization tempering module, a dewatering module, a drying / desiccation module, a pyrolysis desorption module, a pyrolysis carbonizing module, a flue gas treatment module, a wastewater treatment module and an auxiliary module; 2) sludge variety determining: determining the sludge variety according to the oil content or resource of the sludge; 3) selecting the modules: selecting the modules required by the treatment process according to the sludge variety; and 4) constructing a system: constructing and assembling a device according to the selected modules.

Description

technical field

[0001] The invention relates to the field of oily sludge treatment, in particular to a method for building a sludge treatment system based on sludge components. Background technique

[0002] According to the different sources of oily sludge, its water content, oil content and solid content are very different, so the treatment of oily sludge is a huge systematic project. The construction method of traditional sludge treatment projects mixes various treatment equipment together, and does not systematically design various treatment processes in modules, resulting in the need for separate design and construction of each treatment project in various sludge treatment projects Handling equipment requires a lot of effort. Contents of the invention

[0003] The purpose of the present invention is to solve the problems in the background technology and provide a method for building a sludge treatment system based on sludge components, which simplifies the process of ...

[0062] Landed sludge treatment, landed sludge is the oily sludge produced by well site operations and pipeline equipment leakage in the process of oilfield exploitation, including crude oil transportation, equipment maintenance and oil well breaking process, crude oil leakage to the ground, blowout and blowout accidents, etc. The crude oil caused by the leakage of crude oil on the ground and other reasons flows to the ground, thereby forming a landing sludge on the ground. Landed sludge contains a mixture of crude oil, sand and gravel, and weeds. The light components are volatilized, and the heavy oil is mainly black, viscous, coarse, and contains a lot of weeds, woven bags, large pieces of gravel, etc. Foreign matter, containing water (5-10%), oil (5-10%), and solid (80-90%).
