Embodiment Construction
[0023] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.
[0024] A method for removing plasticizer in prickly ash oil, it may further comprise the steps:
[0025] (1) Pretreatment: preheating the crude oil of Zanthoxylum bungeanum;
[0026] (2) Distillation: apply external force to Zanthoxylum bungeanum crude oil to increase the activity of its components, and distill Zanthoxylum bungeanum crude oil at the same time to make the light components without phthalate plasticizers and the components rich in phthalates plasticizers Heavy fractions were separated.
[0027] In step (1), the temperature of the Zanthoxylum bungeanum oil crude oil is controlled at 50° C. to 65° C. through the preheating device, and then sent to the dis...

The invention discloses a method and equipment for removing a plasticizer in zanthoxylum oil. The method comprises the following steps: firstly, preheating zanthoxylum oil; and secondly, arranging a centrifugal rotor body and a heating ring plate mechanism surrounding the periphery of the centrifugal rotor body in a distillation cylinder. When preheated zanthoxylum oil enters the distillation cylinder, the zanthoxylum oil impacts on the heating ring plate mechanism under the action of the centrifugal rotor body, under the action of impact force, the activity of molecular components in fluid can be improved, the zanthoxylum oil impacts on the heating ring plate mechanism and can gather to form a film, finally light distillation components and heavy distillation components are efficiently distilled out, and the plasticizer in the zanthoxylum oil can be efficiently removed. The method is simple to operate, low in input cost, energy-saving and environment-friendly, and can be used for efficiently removing phthalic acid ester substances in the zanthoxylum oil, improving the quality of the zanthoxylum oil and ensuring the safety of a product.
Description
technical field [0001] The invention relates to a method and equipment for removing plasticizers in prickly ash oil, and belongs to the technical field of plasticizer removal. Background technique [0002] The "plasticizer exceeding the standard incident" that occurred in recent years has aroused people's further attention and thinking on plasticizers. Phthalate esters are the most common plasticizers, which have a certain effect on plastic molding. As they are used and time goes by, they are continuously released into the atmosphere, soil and waters, causing pollution to the environment, thus affecting potential impact on human health. Due to the low acute toxicity of phthalates, no disasters have been found due to exposure of the human body or the environment to these compounds, but low acute toxicity does not mean that they are safe. In recent years, studies have focused on the risk of vegetable oil plasticizer pollution and related risk prevention and control measures....
