Specific embodiment
Hereinafter, referring to the drawings embodiments of the present invention are illustrated.
Fig. 1 is the manufacture method and the flow process and composition of manufacture system of the regeneration heavy oil for schematically illustrating the present invention Figure.
First, various waste oil are reclaimed and is stored in tank T1.Can advise for JIS as the waste oil of the process object of the present invention Regeneration heavy oil suitable with the heavy oil from A heavy oil to heavy oil B in lattice.As such waste oil, except engine oil, gear oil, ATF Beyond the lubricating oil such as (Automatic Transmission Fluid), bobbin oil, working oil and cutting oil, also clean Oil, the processing oil from mineral oil, the heavy oil kind for going out of use etc..Usually contain in these waste oil considerable amount of moisture (average 6~ 16 weight % or so).In addition, the also foreign body of the solid constituent containing all size.
In existing regeneration Heavy oil treatment method, heating evaporation, centrifugation are carried out to remove moisture, but in order to Make moisture amount less than 1 weight %, need large-scale distillation equipment etc., so as to cost uprises.The present invention is provided and can be use up Amount simply manufactures method and device of the moisture less than the regeneration heavy oil of 1 weight %.
(floating separation procedure)
The waste oil for being stored in tank T1 is sent to the 1st heater H1 using pump P1.1st heater H1 possesses following knot Structure:Heat-exchange pump is equipped with can container, heat-exchange pump is connected with the steam generator outside can container.It is filled into and carries Waste oil in the tank of the heat exchanger is heated to the appropriate temperature of 40~60 DEG C of scopes, preferably from about 50 DEG C.After the heating Under state, the time of regulation is waited until waste oil is separated into two-layer.After waste oil is separated into two-layer, the top section that will only float Liquid takes out and is sent to subsequent processing.The underclad portion being removed in the floating separation procedure is almost moisture.
(the 1st solid-liquid separation process)
Make the drainage screen by the segregation apparatuss as the 1st solid-liquid separation process by the liquid of floating separation procedure acquisition S1.In the 1st solid-liquid separation process, the foreign body of the solid constituent more than about 0.8mm is removed.Liquid after drainage screen S1 Body is recycled to tank T2.
(the 2nd solid-liquid separation process)
Make to be recovered to the centrifugation of the liquid by the segregation apparatuss as the 2nd solid-liquid separation process of tank T2 by the use of pump P2 Machine S2.The tiny segregator CF150 that centrifugal separator S2 is made for such as Dongdu separator industry (strain).In the 2nd solid-liquid separation work In sequence, the foreign body of the solid constituent more than about 5 μm is removed.Liquid after tiny segregator S2 is recycled to tank T3.
(heating and three phase centrifugation separation circuit)
The liquid for being recovered to tank T3 is sent to the 2nd of the leading portion as heating and three phase centrifugation separation circuit by the use of pump P3 Heater H2.2nd heater H2 is identical with the 1st heater H1 by for the can container structure of heat exchange is carried out with vapor Into.The liquid being filled in the tank with heat exchanger is heated to the appropriate temperature of 80 DEG C~100 DEG C of scopes, preferably from about 90℃.Liquid after heating is imported into the three phase centrifugation seperator S3 of back segment.
Autojector (セ Le Off ジ エs of the three phase centrifugation seperator S3 of back segment for such as mitsubishi chemical industry machine (strain) society Network タ mono-) SJ150J.The liquid of waste oil is separated into light liquid, heavy-fluid and greasy filth by three phase centrifugation seperator S3.Thus, oily conduct Light liquid is separated, and water is separated as heavy-fluid, and the solid constituent of 0.1~5 μ m is separated as greasy filth (also containing moisture). Light liquid is recycled to tank T4, and heavy-fluid is recycled to tank T5, and greasy filth is recycled to tank T6.Additionally, heavy-fluid is sent to tank using pump P5 T8 is simultaneously processed in incinerator.Greasy filth is sent to tank T9 using pump P6 and is processed in incinerator.
(moisture evaporation operation)
The light liquid for being obtained and be recovered to by heating and three phase centrifugation separation circuit tank T4 is sent to the 3rd heating using pump P4 Device H3.3rd heater H3 is identical with l and the 2nd heater H1, H2 by for the tank of heat exchange is carried out with vapor Container is constituted.The light liquid being filled in the can container with heat exchanger is heated to the temperature of 100 DEG C~110 DEG C of scopes, It is preferred that the temperature of 103 DEG C~105 DEG C of scopes.Circumferentially it is stirred using blender in can container, also, under can container Portion is provided with mixing pump, carries out the stirring of above-below direction.Thereby, it is possible to the light liquid being uniformly heated up in can container, water can be made Divide from light liquid and evaporate with integrally not staying omission.And, it is preferable that by the pressure in can container is adjusted to malleation, suitably press down The intrusion of air processed.Thus, even if the evaporation of low volatile oil can also suppress to ignite and on fire.
In the case where the treating capacity of light liquid is more, the temperature of the 3rd heater H3 is set to higher.In addition, for oil Water separates the situation of waste oil being difficult to, can by be combined as reducing 1 treating capacity, by temperature be set as it is higher, Extend process time and reinforcing mixing power in 1 or it is multiple, improve moisture evaporation ability.
Moisture evaporation is made by the process of the operation is carried out to light liquid, and the moisture amount of remaining liquid can be made Less than 1 weight %.Tank T7 is sent to using pump P7 through the liquid of moisture evaporation operation, is stored as regeneration heavy oil.
In the regeneration heavy oil manufacture method and manufacture system of the above-mentioned present invention, the 1st~the 3rd heater is respective Steam generator can have a steam generator without the need for separately arranging.General vapor is produced Device can produce 0.1~5MPa, 110~250 DEG C of vapor.As steam generator (or vapor heat exchange Device) can be using the oily-water seperating equipment of such as (strain) group paulownia industry.
The regeneration heavy oil manufacture method and manufacture system of the present invention is by steaming by general equipment for separating liquid from solid, based on water The heater and three phase centrifugation seperator of gas is most combined as and obtains, can with low cost manufacture moisture amount less than The regeneration heavy oil of 1 weight %.
The result after above-mentioned embodiments of the present invention are repeatedly implemented is summarized, it is as follows.
Waste oil:55~70kL
Regeneration heavy oil:45~60kL
The water quantities of the waste oil of before processing:6~12 weight %
The water quantities of the regeneration heavy oil after process:0.6~0.8 weight %
