Described novel refining deodour method, wherein, oil product overflows to after at the bottom of the tower of deodorization filling material tower, also comprises step:
Carry out heat exchange process through vacuum interchanger and bleached oil, complete deodorising process.
Described novel refining deodour method, wherein, be provided with tubulation skin and tubulation internal layer in described vacuum interchanger, refining oil walks tubulation skin, and bleached oil walks tubulation internal layer simultaneously, and vacuum interchanger inside is in vacuum condition, realizes heat exchange object.
Described novel refining deodour method, wherein, before being driven into the tower top of deodorization filling material tower, also comprises at oil product:
By secondary heater, heat treated is carried out to oil product, make oil product temperature be increased to 250 DEG C.
Beneficial effect: the present invention is by after being heated to 240 ~ 250 DEG C by oil product by primary heater, enter into deodorization plate column overhead and carry out deodorization process, oil product in deodorization plate tower flows at the bottom of the tower of deodorization plate tower through overflow or draining valve, then oil product is driven in the tower top of deodorization filling material tower, the packing material for removing oil product free fatty acid is provided with in deodorization filling material tower, oil product is after the process of packing material, overflow at the bottom of the tower of deodorization filling material tower and obtain last refining oil, the present invention removes oil product free fatty acid fast by setting up a deodorization filling material tower, thus realize preparing low-antiform acid, the refining oil product of low free fatty acids, improve product quality.
Accompanying drawing explanation
Fig. 1 is the equipment structure chart of novel refining deodour method of the present invention.
Embodiment
The invention provides a kind of novel refining deodour method, 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.
The preferred embodiment of one provided by the present invention novel refining deodour method, it comprises step:
As shown in Figure 1, after oil product is heated to 240 ~ 250 DEG C by primary heater 100, concrete Heating temperature can be 240 DEG C, 245 DEG C or 250 DEG C, to improve deodorising effect, enter into deodorization plate tower 110 tower top and carry out deodorization process, draining valve is provided with in deodorization plate tower 110, oil product in deodorization plate tower 110 flows at the bottom of the tower of deodorization plate tower 110 through overflow or draining valve, then oil product is driven in the tower top of deodorization filling material tower 130, the packing material for removing oil product free fatty acid is provided with in deodorization filling material tower 130, oil product is after the process of packing material, overflow at the bottom of the tower of deodorization filling material tower 130 and obtain last refining oil, then fuel-displaced.
Concrete, the present invention arranges described deodorization filling material tower 130 after deodorization plate tower 110, by arranging packing material in this deodorization filling material tower 130, thus realize the content removing oil product free fatty acid fast, because the deodorization temperature in deodorization plate tower 110 before controls at a lower level, so the requirement of low-antiform acid can be met, the object reducing free fatty acid content can be met again.
In addition, in order to ensure that temperature in deodorization filling material tower 130 is in higher level, so also carried out heat treated before oil product enters into deodorization filling material tower 130, a secondary heater 120 pairs of oil products specifically can be set before deodorization filling material tower 130 and carry out heat treated, make oil product temperature be increased to 250 DEG C, thus make free fatty acids removal effect better.This secondary heater 120 and aforesaid primary heater 100 are and are heated by steam, namely pass into steam to improve grease temperature.
In the present embodiment, in deodorization plate tower 110, being also provided with draining valve, by regulating the switch of draining valve can control the residence time of oil product in deodorization plate tower 110 flexibly, thus meeting the requirement to trans acids and free fatty acids.
Overflow at oil product after at the bottom of the tower of deodorization filling material tower 130, also comprise step:
Carry out heat exchange process through vacuum interchanger 140 and bleached oil, complete deodorising process.This vacuum interchanger 140 inside is vacuum state, bleached oil is through carrying out heat exchange with the oil product of deodorization before, thus make use of heat energy, realize rapid heating bleached oil, further, in described vacuum interchanger 140, be provided with tubulation skin and tubulation internal layer, refining oil walks tubulation skin, bleached oil walks tubulation internal layer simultaneously, and vacuum interchanger inside is in vacuum condition, realizes heat exchange object.
Bleached oil heats through primary heater 100 after vacuum interchanger 140 again, through deodorization plate tower 110, through deodorization filling material tower 130, through vacuum interchanger 140, so repeatedly completes deodorising process; Another program is: bleached oil heats through secondary heater 120 after vacuum interchanger 140 again, through deodorization filling material tower 130, complete deodorization through vacuum interchanger 140, namely not through primary heater 100 and deodorization plate tower 110, shorten deodorization time, to reduce trans acids as far as possible.
In sum, the present invention is by after being heated to 240 ~ 250 DEG C by oil product by primary heater, enter into deodorization plate column overhead and carry out deodorization process, oil product in deodorization plate tower flows at the bottom of the tower of deodorization plate tower through overflow or draining valve, then oil product is driven in the tower top of deodorization filling material tower, the packing material for removing oil product free fatty acid is provided with in deodorization filling material tower, oil product is after the process of packing material, overflow at the bottom of the tower of deodorization filling material tower and obtain last refining oil, the present invention removes oil product free fatty acid fast by setting up a deodorization filling material tower, thus realize preparing low-antiform acid, the refining oil product of low free fatty acids, improve product quality.
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.
