Abstract
The invention discloses a kind of using waste cooking oil as solid alcohol of raw material and preparation method thereof and equipment.The solid alcohol can quickly be prepared with one-step method：Using waste cooking oil as raw material, sodium hydroxide solution and absolute ethyl alcohol are added in, after reacting at a certain temperature, casting forms solid alcohol after cooling.Present invention process is simple, of low cost, and the obtained solid alcohol burn time is long, flame stabilization, can effective recycling waste cooking oil, prevent it from again flowing into and dining table and cause secondary pollution.
Description
Technical field
The present invention relates to a kind of recycling of waste cooking oil and the preparation method of solid alcohol and Preparation equipments, are related to providing
Source recycles and solid fuel field.
Background technology
Waste cooking oil refers to the animal and plant fat that can not be eaten again that restaurant unit etc. generates in production and operation, this kind of useless
Not only nutritive value is low for grease, also contains there are many harmful ingredient, such as phenols, ketone, free fatty, aliphatic acid
Polymer, aflatoxins, heavy metal etc..If waste cooking oil is not recycled, valuable natural resources is not only wasted, can also
Secondary pollution is caused to natural environments such as water bodys.More seriously, after a large amount of waste cooking oils process refinement by criminal
Dining table is back flowed back into, grave danger is caused to the health of the people.Therefore, the recycling of waste cooking oil can be become give up into
Treasured is turned harm into good, and ensures food safety conscientiously and the people is physically and mentally healthy, have important scientific research, economy and social effect.
Currently, mainly there is following approach in China to the recycling of waste cooking oil：（1）Gutter oil is pre-processed
Afterwards, by saponification, saltout, wash, the processes such as dryness finalization, produce soap and washing powder；（2）Waste cooking oil is suitably being catalyzed
Under the action of agent, biodiesel fuel is prepared with generation ester exchange reactions such as methanol；（3）After waste cooking oil is pre-processed,
It hydrolyzes under suitable condition, refine the chemical products such as acquisition stearic acid, oleic acid, glycerine or further produce fatty acid amide
Wait surfactants or intermediate, etc.（Liang Fanghui, Yin Pinghe, Zhao Ling, Wang Yao Production of Non-phosphate Laundry Powder Through Decolorated Waste Oil
Research [J] Guangdong chemical industry, 2005,9: 5-8；The technique of Wei Zhengyan, Shang Xue ridge waste cooking oils and orange peel soap system

Chen Ligong, Cao Shuhan waste cooking oils produce research [J] Chinese oils of fatty diglycollic amide, and 2013,38:
55-59）.Although these types of approach can recycle gutter oil, all there are certain deficiencies：Such as soap and washing powder production
Product added value is too low；For chemical products obtained by biodiesel and grease hydrolysis although profit is relatively high, production equipment is complicated,
Technological difficulty is higher etc..The heavy industrialization that these shortcomings all hinder gutter oil in various degree recycles.Therefore,
It is necessary to further explore the new way of gutter oil recycling.
Solid alcohol is a kind of novel solid fuel, long with burning time compared with liquid ethanol fuel, flame temperature
Degree is uniform, and calorific value deviation is smaller, facilitates beauty, safely the advantages such as portable, is widely used in catering trade, tourist industry and field and makees
Industry.The preparation method of current main-stream is solidification of the odium stearate that stearic acid is used to be generated after being reacted with sodium hydroxide as ethyl alcohol
Agent（Jia Changying, Tang Lihua, Zhang Xiaojuan, in David, Zhang Danyang, Fan You, the preparation process of Li Wei China solid alcohols with
Performance study [J] Shenyang University of Technology journal, 2007,29: 596-600）.The predecessor of waste cooking oil is natural oil,
Main component is triglycerides, and triglycerides saponification under the base catalysis such as sodium hydroxide can generate more comprising odium stearate etc.
The mixture of kind fatty acid sodium salt, therefore, waste cooking oil has the possibility as solid alcohol coagulator after alkali process.So
It is and currently very rare as the report of Material synthesis solid alcohol using waste cooking oil.We are given up in the research of early period with food and drink
Oil after pretreatment, saponification, saltouing, filtering, saponification resultant is dried, using saponification resultant as coagulator, one for raw material
Determine after ethyl alcohol dissolving is added at temperature, casting obtains the cheap solid alcohol prepared using gutter oil as raw material for the first time（It is old
Large flat, Deng Jing, Chen Xin, Fang Liang prepare the method [P] of solid alcohol, Chinese invention patent ZL using waste cooking oil as raw material
201310238829.4.）.Though the method can prepare solid alcohol by raw material of waste cooking oil, saponification is needed, saltouts, filter, doing
Multiple steps such as dry were taken more than 8 hours, and step is relatively complicated, does not meet the demand of large-scale industrial production, and therefore, having must
Explore the new method that solid alcohol is prepared with waste cooking oil.
Invention content
It is a kind of using waste cooking oil as solid alcohol of raw material and preparation method thereof and equipment present invention aims at providing.It can
With by simple one-step method, in synthesis in 30 minutes or so, acquisition can be stabilized at room temperature, and burning time is long, and flame is steady
Fixed solid alcohol, while effective recycling waste cooking oil.
It is a further object to provide Preparation equipments.
Realize the object of the invention the technical solution adopted is that：
By waste cooking oil, sodium hydroxide solution and absolute ethyl alcohol according to mass ratio (4 ~ 5): (4.5~5.5): (35~40)
Mixing, in 80 °C ~ 100 °C lower heating stirrings 30 minutes, injection mold molding, after cooling gelling it is figurate to form tool
Solid alcohol.
Above-mentioned sodium hydroxide solution is prepared according to laxative remedy：By sodium hydrate solid and deionized water according to mass ratio (2 ~
2.5) :(2.5 ~ 3) it is mixed, after forming homogeneous phase solution, is cooled to room temperature.
The waste cooking oil can be but be not limited to：Waste cooking oil restaurant unit is eliminated useless after multiple frying barbecue food materials
Oil, the post-job oily bottom of restaurant unit culinary art, the waste oil in resident's smoke exhaust ventilator oil catcher.
Solid alcohol prepared by the present invention is the translucent gelinite of yellow, and uniformity is good, stablizes at room temperature, conveniently takes
Band, it is cheap.The solid alcohol is easily lighted, and burning time is long, even flame, and no black smoke peculiar smell can be used for generally eating
Industry, tourist industry and field work occasion are drunk, and can effective recycling waste cooking oil.Compared to the patent preparation method of early period（It is old
Large flat, Deng Jing, Chen Xin, Fang Liang prepare the method [P] of solid alcohol, Chinese invention patent ZL using waste cooking oil as raw material
201310238829.4.）, one-step synthesis method is realized, step significantly simplifies, and preparation time greatly shortens, and is more suitable for work
Industry metaplasia is produced.
