Abstract
The invention discloses a method for refining a biodiesel. Under a situation that no catalyst is available, a process for producing the biodiesel by using swill-cooked dirty oil as a raw material comprises four procedures of raw material pretreatment, esterification and alcoholysis, reduced pressure distillation as well as aftertreatment; obviously, the process is more complicated than a process for an edible oil and is high in cost but is cheaper than the edible oil. In order to eliminate the swill-cooked dirty oil, efforts in cracking down peddlers must be increased on the one hand and the cost of the biodiesel must be reduced on the other hand. According to the invention, through the adoption of oil permeable and water impermeable characteristics of a Fusheng sand product, a process for continuously producing the biodiesel by using the swill-cooked dirty oil or waste oil is improved. A bottom filter screen of a filtering quasi-column container is made by using Fusheng sand, and then primarily machined swill-cooked dirty oil with impurities removed are poured into the container, the oil is filtered and separated from water, and then the filtered oil is esterified and alcoholized, distilled in a pressure reduced state and after-treated.
Description
Technical field
The present invention relates to a kind of method of refining biofuel.
Background technology
Sewer oil generally comprises the waste grease of hogwash fat, frying waste oil, food and relevant enterprise generation etc.Along with the raising of day by day exhausted and rise and people's environmental consciousness of petroleum-based energy price, the exploitation paces of alternative fuel have been accelerated in countries in the world, and the sewer oil that is used for the earliest producing soap or soap lye has become the cheap raw material of biofuel.Generally there is ash on the surface of sewer oil from look greasy floating matter and swill, also has underground sanitary sewage, fruits and vegetables septic matter, domestic refuse etc., and oil is chocolate, and is opaque, and strong sour foul odour is arranged, and zero pour is high
The course of processing of sewer oil has three process: the processing of at first decolouring, after fully stirring in a large amount of carclazyte adding sewer oils, pour filter into, and oil becomes limpid and acid number reduces greatly; Second step is washing, the oil of decolouring is poured into do not stopped in the large pond to stir, and removes water-soluble impurity and throw out, more further decolouring; Final step is the vacuum deodorizing, the oil of processing is put into the vacuum tank heating vacuumize the removal peculiar smell.Sewer oil color clarification through this art breading without obvious peculiar smell, is easy to escape the inspection of hygiene department.Under the driving of sudden huge profits, add that the cost compare that utilizes the sewer oil processing biological diesel-oil is high, caused illegal retailer to advance wave upon wave, use in a large number sewer oil to produce edible oil, sell hotel and dining room, greatly endangered the healthy of people.
In the situation of catalyst-free, take the technique of sewer oil as the raw material production biofuel: comprise raw materials pretreatment, esterification alcoholysis, underpressure distillation and four operations of aftertreatment; Obviously its technique is than the complex process of edible oil, cost height and market value is lower than edible oil.Reason that sewer oil remains incessant after repeated prohibition that Here it is.So stop sewer oil, must work along both lines, strengthen on the one hand the hitting dynamics to illegal retailer, to suitably improve on the one hand the purchasing price of biofuel, reduce simultaneously its production cost.
" inspire confidence in and contain sand " that China inventor Qin Shengyi utilizes sand to produce has selective permeation, and its know-why is exactly with the film of grains of sand surface parcel one deck as eggshell, because this film can increase the interfacial tension of water, reduces the interfacial tension of oil; This oily sand is fully waterproof under the certain pressure condition, mainly oily, thereby bringing into play thoroughly oily fluid-tight effect, be mainly used at present in the exploitation in nonmarine deposit oil field, because profit symbiosis, propping agent with oily water stop function can make the oil infiltration pass through, and water can not pass through, and greatly reduces the water ratio of oil; Thereby oil production rate and quality have been improved.
Summary of the invention
The present invention utilizes thoroughly oily fluid-tight characteristic of " inspire confidence in and contain sand " product exactly, improves the technique of sewer oil or waste oil continuous production of biodiesel.The bottom screen of the plan column container that will filter is exactly made with " inspire confidence in and contain sand ", then process is picked deimpurity elementary finished sewer oil, pour in the container, utilize " inspire confidence in and contain sand " its saturating oily fluid-tight effect, oil filter out with moisture from, then the oil that filters is carried out esterification alcoholysis, underpressure distillation and four operations of aftertreatment.
The inventive method can decrease sewer oil pre-treatment cost, raises the efficiency; Can solve effectively that the biofuel cost is high, yield rate is low and the problem such as long reaction time, in the production process without three wastes problem, environmental protection, operation and energy consumption are low easily, are fit to large-scale industrial production.Although just improved step of simple raw materials pretreatment, this link is extremely important, because it has determined the production efficiency of biofuel and the height of cost.
Embodiment
Below in conjunction with embodiment, the present invention is described in further details.
Buy an amount of " inspire confidence in and contain sand " material from factory, it is processed into round, and be installed in the bottom of intending the cylinder filter plant.With the sewer oil of collecting, render in the pretreated large pond, remove the larger impurity such as floating matter.
Concrete technique is that 1. sewer oil is placed in the feed reservoir, the outlet of feed reservoir has airtight pipeline to be connected to the top of intending the cylinder filter plant, pass through sump pump, pretreated sewer oil is pumped into the plan cylinder continuously, the below of plan cylinder has been placed the top of clean container plan cylinder and has been offered an aperture, and moisture and the impurity sewer oil separated by tubule export to wastewater disposal basin, can be used as fertilizer processing.Then continue sewer oil is carried out oily water separation, for new sewer oil raw material soars, whole process can be finished in automatization.The sewer oil that is filtered out directly enters esterification alcoholysis, underpressure distillation and 3 operations of aftertreatment.
The present invention uses and has opened up more wide space for " inspire confidence in and contain sand ", because petroleum resources can be exhausted, but sewer oil is accompanied by the mankind possibly always, believe that technique of the present invention is bound to obtain good economic benefit and social benefit, reduce simultaneously the harm of sewer oil, significantly reduced the harm of Desertification.
Claims (2)
1. a method of refining biofuel is characterized in that the filter plant bottom of sewer oil adopts saturating oil fluid-tight " inspire confidence in and contain sand " material to make.
2. the method for refinement biofuel according to claim 1 is characterized in that by sump pump, pretreated sewer oil is pumped into filter plant intend cylinder; Intend the top of cylinder and offered an aperture, and by tubule the isolated water of sewer oil and impurity are exported to wastewater disposal basin, the sewer oil that is filtered directly enters esterification alcoholysis, underpressure distillation and 3 operations of aftertreatment.
