1. equipment that is used to reclaim waste lubricating oil, said equipment comprises:

  • First vaporizer, said first vaporizer can heat said waste lubricating oil to scope be 70 to 240 ℃

    temperature from said waste lubricating oil, forming the steam of hydrocarbon, water and terepthaloyl moietie,Wherein said first evaporation apparatus is useful on first condensing surface of reception and the said steam of condensation;

    First separator of the liquid of separating and condensing from the uncooled steam of said first condensing surface;

    And be used for from said first separator compression said uncooled steam to environment or be higher than first compressor of environmental stress;

    Be used for first end pump that is connected to said first vaporizer of the said waste lubricating oil of pumping thus,Wherein the said waste lubricating oil of the part through said first end pump pumping is via the said first vaporizer recycling;

    Second vaporizer with heat-transfer pipe of vertical layout;

    Said second vaporizer is that 6 to 30mbar pressure is operated down in the scope of measuring like said heat-transfer surface place;

    Through distributing said second vaporizer of said oil can be with being that the said waste lubricating oil from said first end pump under 70 ℃

    to 240 ℃

    the temperature is heated to 200 ℃

    to 290 ℃

    temperature in scope;

    To form through the stream film on the tube surface;

    Said heat-transfer pipe has the heating medium under 230 ℃

    to 380 ℃

    temperature on its other surface, thereby mainly forms from the diesel oil of said waste lubricating oil and the steam of light vacuum cut diesel oil in the surface of heat-transfer pipe;

    Wherein said second evaporation apparatus is useful on second condensing surface of reception and the said steam of condensation;

    Second separator that from the uncooled steam of said second condensing surface, separates the liquid of said condensation;

    And be used for from said second separator compression said uncooled steam to environment or be higher than second compressor of environmental stress;

    Be used for second end pump that is connected to said second vaporizer of the said waste lubricating oil of pumping thus,Wherein the said waste lubricating oil of the part through said second end pump pumping is via the said second vaporizer recycling;

    The 3rd vaporizer with heat-transfer pipe of vertical layout;

    Said the 3rd vaporizer is operation and can the said waste lubricating oil from said second end pump under 200 to 290 ℃

    temperature be heated to 250 ℃

    to 320 ℃

    through distributing in each of said oil to a plurality of heat-transfer pipes under the pressure of 0.5-15mbar in scope;

    To be formed on the lip-deep stream film of each said heat exchanger tube;

    It is 300 to 380 ℃

    heating medium that said heat exchanger tube has temperature in other surperficial cocycle of said heat-transfer pipe, thereby mainly forms the heavy gas oil steam from said waste lubricating oil in the surface of the pipe of said vaporizer;

    Wherein said the 3rd evaporation apparatus is useful on the 3rd condensing surface of reception and the said steam of condensation;

    The 3rd separator that from the uncooled steam of said the 3rd condensing surface, separates the liquid of said condensation;

    And be used for from said the 3rd separator compression said uncooled steam to environment or be higher than the 3rd compressor of environmental stress;

    AndBe used for the 3rd end pump that is connected to said the 3rd vaporizer of the said waste lubricating oil of pumping thus,Wherein the said waste lubricating oil of the part through said the 3rd end pump pumping is the waste lubricating oil that reclaims via said the 3rd vaporizer recycling and said remainder.
