Abstract
The invention discloses a kind of Sludge in Oilfields break process techniques, belong to Sludge in Oilfields environmental protection treatment technical field.The specific steps are that: contaminated soil is dug out using excavator and is stacked as the heap body of the long a height of 10*2*1m of * wide *, and is dried；Oily sludge moisture content after sunning is detected, adds sandy soil when moisture content is 50%；The oily sludge moisture content for adding sandy soil is detected, oily sludge is crushed using high speed disintegrator when moisture content is lower than 30%；Broken oily sludge is sieved using sieving machine, partial size is more than that the oily sludge of 5mm is crushed further, and oily sludge of the partial size less than or equal to 5mm carries out subsequent processing.This process flow is simple, homogenizes the oily sludge in soil by broken and screening, tinyization, reduces subsequent processing difficulty, can effectively reduce the reaction time, make treatment effect good.
Description
Technical field
The present invention relates to Sludge in Oilfields environmental protection treatment technical field, specially a kind of Sludge in Oilfields break process
Technique.
Background technique
The compound for a kind of complexity that oily sludge is made of water oil, water oil emulsion and suspended solid, comprising various
Alkane, aromatic hydrocarbon etc..China generates nearly million tons of oily sludge every year.How harmless treatment is carried out to it, had become
One technical problem urgently to be resolved.Sludge in Oilfields is because its viscosity is big, colloid is more, is being handled caused by poor fluidity
Shi Rongyi is cementing, increases processing difficulty.For the difficult point, the present invention proposes a kind of Sludge in Oilfields break process technique.
Summary of the invention
In order to achieve the above objectives, the present invention proposes a kind of Sludge in Oilfields break process technique.The following steps are included:
(A) oily sludge is excavated and stacks, dries；
(B) the oily sludge spike that will be stacked in step (A)；
(C) oily sludge of spike in step (B) is crushed；
(D) oily sludge crushed in step (C) is sieved.
Further, it tells to excavate oily sludge according to the sequence of from low to high in step (A) and stack, stack for long *
Wide * high is respectively the heap body of 10*2*1m, and site requirements meets national standard HJ 2035-2013, is needed in digging process pair
Boundary soil is constantly detected, until in soil without obvious hydrocarbon.
Further, the oily sludge moisture content of sunning is detected in the step (A).
Further, spike is mainly to add sandy soil in 50% oily sludge to moisture content in the step (B).
Further, the crushing in the step (C) will mainly mix oily sludge of the moisture content 30% after sandy soil
It is crushed.
Further, mainly high speed disintegrator is utilized to complete the crushing of oily sludge in the step (C).
Further, the screening of oily sludge is carried out using the sieving machine that aperture is 5mm in the step (D), will
Oily sludge particle of the partial size less than or equal to 5mm is further processed.
Further, after the screening of oily sludge screens out the oily sludge that partial size is more than 5mm in the step (D)
It is crushed once entering step (C).
The invention has the benefit that
This construction technology process is simple, homogenizes the oily sludge in soil by broken and screening, tinyization, reduces
Subsequent processing difficulty can effectively reduce the reaction time, make treatment effect good.
