Embodiment Construction

[0019] The present invention provides a pre-decolorization method and device. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] A kind of pre-decolorization method preferred embodiment of the present invention, it comprises steps:

[0021] A. After mixing the decolorizing agent and the oil, decolorize in the decolorizing tank;

[0022] B, the mixture of the decolorization treatment is squeezed into the first decolorization filter for filtration;

[0023] C. Put the new oil directly into the first decolorization filter for pre-decolorization treatment;

[0024] D, after the oil product after the pre-decolorization treatment in step C is mixed with the decolorizer, carry out decolorization treatment...

Abstract

The invention discloses a pre-decolorizing method and device. The method comprises: S1, mixing a decolorizing agent with oil and then carrying out decolorizing treatment in a decolorizing tank so as to obtain a decolorized mixture; S2, infiltrating the decolorized mixture into a first decolorizing filter and carrying out filtering treatment; S3, directly infiltrating new oil into the first decolorizing filter and carrying out pre-decolorizing treatment; S4 mixing the oil which is subjected to pre-decolorizing treatment in the step S3 with the decolorizing agent, and then carrying out the decolorizing treatment in the decolorizing tank so as to obtain a mixture; and S5, directly infiltrating the mixture which is subjected to the decolorizing treatment in the step S4 into a second decolorizing filter and carrying out filtering treatment. According to the pre-decolorizing method and device, the target of secondary utilization on a waste decolorizing agent is achieved; the use amount of the decolorizing agent is lowered; and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of refining decolorization, in particular to a pre-decolorization method and device. Background technique [0002] In the decolorization section of the refining process, the pigment in the oil is absorbed and filtered by the decolorizer to realize the decolorization of the oil. In the decolorization process in the prior art, the oil is generally heated, then the decolorizer is added, stirred and mixed, and then Decolorization is carried out in the decolorization tank, and finally the waste decolorizer is discharged through the filter to complete the decolorization. The disadvantages of the prior art are: the decolorizing efficiency of the decolorizing agent is not maximized, the amount of the decolorizing agent added in the decolorizing process of the oil is relatively large, and the used decolorizing agent cannot be reused. [0003] Therefore, the prior art still needs to be improved and developed. Conte...
