Described pre-decoloration device, wherein, also comprises the bleached oil temporary storage tank of a connection discoloring agent mixing tank, for the temporary bleached oil through filtering.
Beneficial effect: the present invention carries out desolventing technology after being mixed with oil product by discoloring agent in bleacher; Then the mixture of desolventing technology is driven into the first decolorizing filter and carries out filtration treatment, after filtration completes, do not carry out oil extraction blow cake program, but new oil product is directly driven into the first decolorizing filter carries out pre-desolventing technology; And then after being mixed with discoloring agent by the oil product after pre-desolventing technology, carry out desolventing technology, thus reach the object of useless discoloring agent being carried out to second stage employ, decrease the usage quantity of discoloring agent, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pre-decoloration device preferred embodiment of the present invention.
Embodiment
The invention provides a kind of pre-decoloring method and device, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
A kind of pre-decoloring method preferred embodiment of the present invention, it comprises step:
A, discoloring agent is mixed with oil product after in bleacher, carry out desolventing technology;
B, the mixture of desolventing technology is driven into the first decolorizing filter carries out filtration treatment;
C, new oil product is directly driven into the first decolorizing filter carries out pre-desolventing technology;
D, the oil product in step C after pre-desolventing technology is mixed with discoloring agent after, in bleacher, carry out desolventing technology;
E, the mixture through desolventing technology in step D is driven in the second decolorizing filter and carries out filtration treatment.
Technique scheme is relative to the improvements of prior art, first decolorizing filter is after normal filtration treatment, cake program is blown in the oil extraction not carrying out next step, but the oil product not adding discoloring agent is directly entered into this first decolorizing filter, the old discoloring agent in this first decolorizing filter is utilized to filter, simultaneously, oil product is through the pre-desolventing technology of the discoloring agent of this first decolorizing filter, oil product its color and luster after pre-decolouring has decline by a relatively large margin, then decolour carrying out mixing with discoloring agent, the amount of now required discoloring agent just significantly reduces, and decolorizing effect is better.
Further, described discoloring agent is carclazyte.
The change of above-mentioned steps, the change of equipment pipe trend must be embodied, in the present embodiment, the trend of transformation pipeline, and revise the schedule of operation of strainer, add pre-decolorization process, make the first strainer after covering filtration step, do not carry out oil extraction and blow cake program, but the pre-decolorization process that gets ahead, oil product is first decoloured through the first strainer spent bleaching clay, and then normally enters the decolouring of decolouring system, reach the object reducing carclazyte consumption.
Specifically, as shown in Figure 1, pre-decoloration device provided by the present invention, it comprises discoloring agent mixing tank 100, bleacher 200, first strainer 300, second strainer 400, described discoloring agent mixing tank 100 connects bleacher 200, described bleacher 200 connects the first strainer 300 and the second strainer 400 respectively, described discoloring agent mixing tank 100 is for mixing discoloring agent with oil product, described bleacher 200 is for carrying out desolventing technology by discoloring agent and the mixed mixture of oil product, described first strainer 300 and the second strainer 400 are for carrying out filtration treatment to the mixture through desolventing technology.Connected by pipeline between each tank, and driven by pump.
Described pre-decoloration device also comprises the drying chamber 500 of a connection discoloring agent mixing tank, for carrying out drying treatment to crude oil.
Described pre-decoloration device also comprises the discoloring agent temporary storage tank 600 of a connection discoloring agent mixing tank, for temporary carclazyte.
Described pre-decoloration device also comprises the bleached oil temporary storage tank 700 of a connection discoloring agent mixing tank, for the temporary bleached oil through filtering.
Traditional decoloration process, its trend is: bleacher 200 → the first strainer 300 → bleached oil temporary storage tank 700, and this mode is comparatively large to the consumption of discoloring agent, and the utilization ratio of discoloring agent is maximized.And trend of the present invention is: bleacher 200 → the first strainer 300 → discoloring agent mixing tank 100 → bleacher 200 → the second strainer 400 → bleached oil temporary storage tank 700, the useless discoloring agent in strainer so just can be made to be fully used, to improve discoloring agent utilization ratio.In addition, after oil product in the first strainer 300 decolours in advance, oil extraction can be carried out and blow cake program, the discoloring agent of being fully used is removed, and cake program is blown in the oil extraction that the second strainer 400 does not carry out next step after filtering, but pre-desolventing technology is carried out to next batch oil product, the useless discoloring agent in so each strainer can be utilized more fully, reaches the object of circular treatment.
In sum, the present invention carries out desolventing technology after being mixed with oil product by discoloring agent in bleacher; Then the mixture of desolventing technology is driven into the first decolorizing filter and carries out filtration treatment, after filtration completes, do not carry out oil extraction blow cake program, but new oil product is directly driven into the first decolorizing filter carries out pre-desolventing technology; And then after being mixed with discoloring agent by the oil product after pre-desolventing technology, carry out desolventing technology, thus reach the object of useless discoloring agent being carried out to second stage employ, decrease the usage quantity of discoloring agent, reduce production cost.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
