Abstract
The utility model discloses an oi contg sewage treatment system, include: coke drum, cold jiao ta, sump oil jar, demulsifier storage tank, blending tank, jiaochi, fractionating tower, wherein, the coke drum exports and links to each other with cold jiaota, and cold jiaota is provided with circulation pipeline and the top links to each other with the sump oil jar, and circulation pipeline is continuous with the entry and the first export of coke drum, fractionating tower, blending tank respectively, and the first export of blending tank links to each other with demulsifier storage tank and sump oil jar respectively, and the second export of blending tank links to each other with jiaochi. The utility model discloses an useful part is: make the oily sewage can abundant with the demulsifier, complete reaction through backward flow stirred tubular line, make the profit fully separate, increase the output of by -product when further purifying waste water, avoided bringing the potential safety hazard because the separation incompletely makes the sump oil of after -separating get into the coke drum, improved oily sewage's degree of finishing dealing with greatly, have very big progressive nature.
Description
Technical field
The treatment system that the utility model discloses a kind of oil-polluted water, belongs to sewage treatment area.
Background technology
Oil plant, in crude Treatment process, can produce a large amount of oil-polluted waters. Generally there are two kinds for the processing of sewage:First method is to use centrifuge separating and dehydrating after adding flocculant to make sump oil form flocculation scum silica frost in sewage, and scum silica frost becomes solidAfter body, pulverize again, mix oil or coal burns, but because its cost is too high, this kind of processing method application fewer and feweri; The secondMethod is to utilize delayed coking reaction to carry out freshening to oil-polluted water, and oil-polluted water is directly sent in Refinery Coking deviceCoke drum, mainly relies on the waste heat after coke drum green coke, and the moisture in scum silica frost, light oil constituents gasification are steamed, and part heavy oil fallsSeparate, oil gas enters fractionating column and reclaims, and heavy oil component and solid impurity in scum silica frost are adsorbed on coke. Second method was both savedScum silica frost disposal cost, increased again the output of oil gas and coke, thereby this processing method is adopted by most refinery.
But above-mentioned second method exists following not enough, after the coking plant of current each refinery and cold Jiao Ta processThe ratio that each component of the oil-polluted water producing is not fixed, can not carry out water-oil separating with appropriate demulsifier complete reaction.Therefore, still there is a certain amount of water in the sump oil of separating, and makes the sump oil reclaiming in this way as quench oil use meetingCause huge potential safety hazard, owing to there is equally sump oil in the sewage of separating, the sewage of this part oil-containing sump oil entersAfter Jiao Chi, can pollute fresh water, can affect petroleum coke product quality, cause production loss, and cannot eradicate the dirt of sewageMetachromia, still can cause environmental pollution after discharge.
Utility model content
For above-mentioned deficiency, the utility model is to provide a kind of oil-containing sewage treatment system.
The utility model is achieved through the following technical solutions:
A kind of oil-containing sewage treatment system, comprising: coke drum, cold Jiao Ta, slop tank, demulsifier storage tank, blending tank, JiaoPond, fractionating column, wherein, described coke drum outlet is connected with cold Jiao Ta, and cold Jiao Ta is provided with circulation line and top and slop tankBe connected, described circulation line is connected with the first outlet with the entrance of coke drum, fractionating column, blending tank respectively, first of blending tankOutlet is connected with slop tank with demulsifier storage tank respectively, and the second outlet of blending tank is connected with Jiao Chi.
As preferred technical scheme, between described circulation line, described cold Jiao Ta and described slop tank, described blending tankFirst outlet with circulation line between pipeline on be provided with the pump housing.
As preferred technical scheme, between described circulation line, cold Jiao Ta and slop tank, be provided with pressure gauge.
Use the concrete operations of carrying out sewage disposal of the present utility model to be: the oil gas after coke drum is steamed out greatly passes into coldJiao Ta, the oil gas of cold Jiao Tanei is carried out cooling, form oil-polluted water, this oil-polluted water is delivered in slop tank, work as sump oilWhen liquid level in tank reaches 60%, to slop tank bottom water injection, make oil-polluted water enter blending tank and mix with demulsifier, pass throughReturn stirring pipeline is uniformly mixed fully, ensures that profit separates completely, then sump oil is entered to fractionating column through circulation lineOr coke drum, residue water injects Jiao Chi.
By adopting above-mentioned technological means, usefulness of the present utility model is:
By return stirring pipeline make oil-polluted water can with demulsifier fully, react completely, profit is fully dividedFrom, when further purifying waste water, increase the output of byproduct, avoid due to the sump oil separating after not exclusively making to separateEnter coke drum and bring potential safety hazard, greatly improved the degree of finishing dealing with of oil-polluted water, there is very much progress.
