Vehicle-mounted oily sludge pyrolysis system

Abstract

A vehicle-mounted oily sludge pyrolysis system comprises a pyrolysis device, a combustor and a diesel oil tank, and is characterized in that the combustor and a pyrolysis flue gas outlet are arranged on the pyrolysis device, the pyrolysis flue gas outlet is connected with an inlet of a flue gas purification device through a pyrolysis flue gas pipeline, an outlet of the flue gas purification device is connected with an exhaust funnel through a gas purification pipeline, the discharging end of the pyrolysis device is provided with a pyrolysis oil gas outlet and a pyrolysis slag outlet, and the pyrolysis oil gas outlet is connected with an inlet of the combustor through a pyrolysis oil gas pipeline; the pyrolysis device is provided with a feeding system, and the feeding system comprises a bucket elevator, an oily sludge hopper, a double-flap valve, a cylinder, a first rotary seal and a rotary roller; and a discharging port of the bucket elevator is connected with a feeding port of the oily sludge hopper, and the lower portion of the oily sludge hopper is connected with the double-flap valve. The vehicle-mounted oily sludge pyrolysis system has the advantages of self power generation, no need of water, suitability for various types of oil sludge, high cost performance, flexibility, thorough treatment and the like.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a vehicle-mounted oily sludge pyrolysis system. Background technique [0002] Oily sludge originates from the exploitation process of oil and gas fields. It mainly includes waste liquid sludge, landed sludge, gathering system sludge, and sewage treatment system sludge. It is a mixture of oil, water, and mud. Wide, outstanding historical issues and other characteristics. The particularity of oily sludge is that it is flammable and explosive, contains water and oil, and has been included in the national list of hazardous waste. Generally speaking, oil and gas fields are located in remote locations, the working environment is difficult, crude oil pollution is mostly sporadic, the cleaning and collection of sludge is extremely inconvenient, and the general lack of water and electricity is not conducive to the construction of large-scale centralized sludge treatment ...

AI Technical Summary

Problems solved by technology

Due to the water-containing and oil-containing characteristics of the oily sludge mentioned above, as well as the complex changes in material properties under various working conditions, such as the water content can change from a very easy flow as high as 85% to a relatively dry state below 50%, which has great impact on The feeding, transportation, and heating desorption of materials have all caused serious difficulties, and the broad-spectrum adaptability of materials needs to be considered

In addition, the oil content of sludge is not constant. When the oil content is low, it becomes uneconomical for the pyrolysis method of recovering oil by condensation, and the condensation method requires a large amount of cooling water and sewage treatment equipment
