Heterotopic flameless burning treatment apparatus and method for oily sludge

Abstract

The invention relates to a heterotopic flameless burning treatment apparatus and method for oily sludge. The apparatus herein comprises a reaction system, an air injection system communicated with thereaction system, a tail gas treatment system fitting the top of the reaction system, and a monitoring adjusting system electrically connected with the reaction system, the air injection system and the tail gas treatment system. In treatment, oily sludge is placed in a reaction zone; the air injection system introduces air into an ignition startup zone; an ignitor is used to ignite the oily sludge; the monitoring adjusting system adjusts air introduction into the ignition startup zone through the air injection system according to temperature data measured by a temperature monitoring mechanism;post-reaction tail gas is collected by the tail gas treatment system and discharged. Compared with the prior art, the apparatus and method have high ignition efficiency and oily sludge treating capacity, low energy consumption, good control convenience and good flexibility.

Description

technical field [0001] The invention belongs to the technical field of oil sludge treatment, and relates to a flameless and smoldering treatment device and a treatment method for heterogeneous oil sludge. Background technique [0002] Oil sludge refers to the sludge generated during the production process of oil fields due to crude oil extraction, storage, gathering, processing, and crude oil production fluid treatment. Oil sludge contains crude oil or certain components of crude oil. As the output of oil sludge continues to increase, if it is not treated and discharged directly, it will not only occupy a large amount of cultivated land, but also pollute the surrounding soil, water, and air; the oil sludge also contains a large number of pathogenic bacteria, parasites (eggs), and heavy metals. , polychlorinated biphenyls, dioxins, radionuclides and other refractory toxic and harmful substances will cause great pollution to the environment and surrounding organisms.

AI Technical Summary

Problems solved by technology

The smoldering method usually uses a resistance rod to directly ignite the sludge, the ignition efficiency is low, and the ignition time is as long as nearly 6 hours, which seriously affects the treatment efficiency, and the viscosity of the directly ignited sludge pollutants needs to meet certain requirements. The oil sludge effect is not good; in the combustion process, the repair medium spreads with the air diffusion, and the propagation rate is restricted by the air transmission efficiency, which is difficult to control

Therefore, problems such as long ignition time and low air transfer efficiency greatly limit the treatment efficiency of smoldering technology
