Abstract
The invention relates to a steel industry water-surface floating oil processing method comprising the sequential steps that: I, water-surface floating oil is fetched; II, the water-surface floating oil is added into a mixing tank; III, a demulsifier with a specification of Novo Force D1190 is added into the water-surface floating oil, wherein an addition amount is 0.5-1% of the volume of the waste oil; and nitric acid with a concentration of 50-70% is added into the floating oil, such that a pH value reaches 2; the mixing tank is heated to 100-110 DEG C, and the floating oil is stratified, wherein the upper layer is oil, the lower layer is sludge which is then delivered to a sludge field, and the middle layer is a mixture; and IV, upper-layer oil is extracted and is detected by using a moisture sensor; when the moisture content in oil is no lower than 1%, the oil is delivered back to the mixing tank; when the moisture content in oil is lower than 1%, the oil is considered as qualified, and is delivered to a first oil storage tank; the oil is processed by using a vacuum-spray dehydration machine, such that the moisture content in the oil is lower than 0.1%; the oil is delivered into a second oil storage tank, and is subjected to active carbon deodorizing, such that floating oil regenerated oil is obtained. The floating oil processed with the processing method provided by the invention can be applied as fly ash brick mold-release oil.
Description
Technical field
The present invention relates to a kind of steel industry floating oil treatment process waterborne, is specifically the method that the cold hot rolling cooling water of a kind of steel industry upper strata suspension waste oil is produced mold oil.
Background technology
In the production of iron and steel enterprise, all kinds of oil products are important source material of the normal operation of guarantee equipment, and the discarded oil product producing after therefore using is also the inevitable outcome of Iron and Steel Production.Accelerating The Construction resource-conserving and environment-friendly society wants Developing Circulation Economy, improves the level of resources utilization, finds new renewable resource, strengthens environment management, and the research of waste oils resource also receives publicity.
The production of steel industry can produce a kind of useless oily substance that is called oil slick waterborne, be because technique or equipment self run, emit, drain to trench in hot rolling, cold-rolling process, be discharged to water-supply plant horizontal flow basin with water of productive use, the suspension waste oil waterborne obtaining through the collection of oil slick machine.This kind oil product oil is poor, water content is high, complicated component, and containing impurity such as mud, lubricated lipid and moisture, most of smelter processing modes are landfills after outward transport, not only cannot directly utilize, and environmental pollution are very large.This processing mode is simply extensive, without economic benefit.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing steel industry floating oil treatment process waterborne, the invention provides the available steel industry of a kind of oil slick floating oil treatment process waterborne.
This steel industry floating oil treatment process waterborne comprises following step successively:
1, with Oil scraper waterborne or the upper oil slick of hydrophobic oleophylic conveying belt water intaking;
2, oil slick waterborne is added to blending bin;
3, emulsion splitter is added in oil slick, add-on is the 0.5-1% of waste oil volume, then to add concentration be that the nitric acid of 50-70% joins in oil slick, and uniform stirring waste oil (stirring velocity is 90-120r/min, and churning time is 15-20min), makes pH=2; Energising in blending bin is heated to 105 ± 5 DEG C; Oil slick layering in case, upper strata is oil, and lower floor is body refuse, and body refuse is transported outward landfill disposal after delivering to the airing mummification of slag field; Middle level is mixture;
4, extract upper strata oil and detect through moisture responsive device, W/O part content >=1% item is sent blending bin back to by pipeline; 1% of W/O part content < thinks qualified, is transported to after the first fuel reserve tank, then enters the processing of vacuum spraying formula water extracter by pipeline, make W/O part be less than 0.1%, enter the second fuel reserve tank, in the second fuel reserve tank, through active carbon deodorizing, obtain oil slick recovered oil.
Above-mentioned steel industry floating oil treatment process waterborne, is characterized in that: the model of described emulsion splitter is Novo Force D1190.
Above-mentioned steel industry floating oil treatment process waterborne, is characterized in that: the model of described emulsion splitter is Novo Force D1180 or Novo Force D3230.
This steel industry floating oil treatment process waterborne, the mold oil that oil slick after treatment can be used as brick making from fly-ash uses, and can realize the utilization of the oil slick waterborne producing in iron and steel enterprise's production; Realize the open pit mining of iron and steel enterprise's oil slick waterborne, not only reduce industrial waste oil generation, reduce refuse processing costs, and the oil slick recovered oil of producing can be used as mold oil.
Embodiment
Describe the embodiment of this steel industry floating oil treatment process waterborne in detail below in conjunction with embodiment, but the embodiment of this steel industry floating oil treatment process waterborne is not limited to following embodiment.
Embodiment
The present embodiment processing be the cold hot rolling cooling water of steel industry upper strata suspension waste oil, main component has lubricating oil, fiber-like solid waste and moisture.
The present embodiment is following step successively:
1, in pond, get 400L oil slick waterborne with hydrophobic oleophylic conveying belt;
2, oil slick waterborne is added to blending bin;
3, be that the emulsion splitter 4L of Novo Force D1190 adds in oil slick by model, then to add mass concentration be 60% nitric acid, uniform stirring (stirring velocity is 90-120r/min, and churning time is 18min), makes its pH=2; Energising heating blending bin to 105 DEG C; Oil slick layering in case, upper strata is oil, and lower floor is body refuse, and body refuse is delivered to Sewage treatment systems processing; Middle level is mixture;
4, extract upper strata oil and detect through moisture responsive device, W/O part content >=1% item is sent blending bin back to by pipeline; W/O part content < 1% sends into the first fuel reserve tank by pipeline, then enters the processing of vacuum spraying formula water extracter, makes W/O part content be less than 0.1%, send into the second fuel reserve tank, through active carbon deodorizing, obtain oil slick recovered oil again, volume is 120L.The detection contrast of the former use mold oil of this recovered oil and flyash factory is as follows:
The oil of the present embodiment processing can be used as the demoulding of coal ash for manufacturing brick field brickmaking process and uses, and when use, oil slick recovered oil is contained in open container, uses to cover with paint or varnish it is evenly spread upon to mould vehicle internal surface, and knockout course is smooth, respond well.
The emulsion splitter of the present embodiment is the emulsion splitter of available model Novo Force D1180 or Novo Force D3230 also.
