Problems solved by technology

[0002] The decolorization of materials in the traditional oil industry is mostly based on activated carbon (powder carbon) and activated clay (CN105038982 A, CN 104987951 A, CN 105037093 A, etc.). There are many disadvantages such as solid waste, high labor intensity of workers, inability to automate operations, low work efficiency, loss of materials, etc.

Embodiment 1

[0056] A system for treating grease with granular carbon in a renewable manner, the system includes a crude oil tank 16, and the crude oil tank 16 is divided into two branch pipelines, which are respectively connected to the lower parts of the adsorption tower I5 and the adsorption tower II6;

[0057] The adsorption tower I5 and the adsorption tower II6 are connected by pipelines;

[0058] The outlets of adsorption tower Ⅰ5 and adsorption tower Ⅱ6 are respectively connected with washing tank Ⅰ8 and washing tank Ⅱ7, and the pipes at the outlets of washing tank Ⅰ8 and washing tank Ⅱ7 are connected to the carbon feeding tank 12, and there is a dehydration screw under the carbon feeding tank 12 Conveyor 20, the discharge part of dehydration screw conveyor 20 is facing the inlet of multi-stage regeneration furnace 13; Tank 1 is connected;

[0059] The lower part of the high-level carbon tank 1 is divided into two pipelines, which lead to the adsorption tower I5 and the adsorption ...

Embodiment 2

[0098] The structure is substantially the same as that of Example 1, the difference is that there is no connected pipeline between the adsorption tower I5 and the adsorption tower II6; that is, the oil to be decolorized can only be selected from the adsorption tower I5 or the adsorption tower II6, or the adsorption tower I5 and the adsorption tower II6. Tower Ⅱ6 decolorizes oil at the same time, and cannot be decolorized twice.

[0099] The oil to be decolorized in the crude oil tank 16 enters the adsorption tower I5 and the adsorption tower II6 respectively, and undergoes decolorization treatment; the rest of the process is the same as that of Example 1.

Embodiment 3

[0101] The structure is substantially the same as that of Example 1, the difference is that there is no connected pipeline between the crude oil tank 16 and the adsorption tower II6; that is, the oil to be decolorized can only be decolorized by the adsorption tower I5 first, and then passed through the adsorption tower II6. Secondary decolorization treatment of oil; or the case of decolorization treatment only by adsorption tower I5.

[0102] The above data prove that the system of the present invention is applied to the decolorization of oils and fats, and its decolorization effect is good, and because most of the granular carbon is recycled and reused in the decolorization process, the cost is saved, and it is a kind of decolorization in the whole decolorization field. Great progress.

Abstract

The invention belongs to the technical field of grease decoloring, and particularly relates to a method for treating grease through granular activated carbon in a reproducible mode and a system thereof. The method comprises the following steps that 1, grease is subjected to decoloring treatment through granular activated carbon in an adsorption tower; 2, saturated carbon formed after adsorption treatment enters a flushing tank to be flushed, then enters a carbon feeding tank, and then is conveyed into a reproduction multi-hearth furnace to be subjected to reproduction treatment; 3, carbon obtained after reproduction treatment is cooled through a quenching groove, received by a blowing groove and then conveyed into a header tank, some novel carbon supplemented to the header tank enters the adsorption tower, and the grease continues to be subjected to decoloring adsorption treatment. The problem that existing activated carbon / granular activated carbon cannot be recycled or reproduced after decoloring is solved, by arranging the reproducible system, carbon obtained after grease adsorption is stripped, burnt and reproduced, the reproduction loss ratio of the granular activated carbon is controlled within 5%, the consumption of the activated carbon is greatly lowered, and the running cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of oil decolorization, and in particular relates to a method for treating oil with granular carbon in a reproducible manner, and also relates to a system used in the method. Background technique [0002] The decolorization of materials in the traditional oil industry is mostly based on activated carbon (powder carbon) and activated clay (CN105038982 A, CN 104987951 A, CN 105037093 A, etc.). There are many disadvantages such as solid waste, high labor intensity of workers, inability to automate operations, low work efficiency, and loss of materials. With the continuous rise in the price of new activated carbon products in recent years, the new "green" technical solution of using regenerated carbon to replace new carbon for the above-mentioned decolorization process has attracted the attention of relevant industrial departments. Granular activated carbon, as the main variety of regenerated carbon, is also wid...
