Description
Technical field
The present invention relates to a kind of bio-fuel-oil, the discarded sewer oil of particularly a kind of utilization is used biological alcohol oil for the feedstock production kitchen range.
Background technology
Sewer oil is a foreign material blended refiltered oil, claims hogwash fat again, number of chemical elements such as interior carbon containing, hydrogen, oxygen, sodium, calcium, potassium, manganese, iron, phosphorus, and staple is stearin and tripalmitin and multiple eating remaining mixture.Sewer oil comprises three types: the one, with the greasy swimmer in the water drain or with leftovers, the oil of leftovers (common name swill) of hotel, restaurant through simply processing, extracting; The 2nd, pork inferior, haslet, pigskin processing and the oil that refines the back output; The 3rd, after the oily access times that are used for fried food product surpass regulation, the abendoned oil that objectionable impuritiess such as peroxide value, acid value exceed standard.Because the sewer oil complicated component, harmful, therefore legal, effectively utilize sewer oil, threaten, avoid environmental pollution all significant reducing food safety.
Existing kitchen range fuel mainly is diesel oil, liquefied gas, piped gas and Sweet natural gas, and biogas is used in the minority rural area.Wherein, The fire temperature of coal gas and liquefied gas is at 400～900 ℃; Can satisfy popular family and medium and small food and drink and use, but can not satisfy 900-1200 ℃ of requirement of big-and-middle food and drink high temperature, and liquefied gas, piped gas exist carbon monoxide to be prone to the potential safety hazard of poisoning; Liquefied gas also has the danger of blast, and often there is generation its accident all parts of the country; And coal gas can not be benefited the common people of urban and urual areas of whole country because of the problem of pipe-line equipment, facility again comprehensively.Sweet natural gas more can not be popularized and promoted in the whole nation by resource limit.Diesel oil has higher combustion heat value, but the burning back produces volume of smoke, has a strong impact on environment.Biological alcohol oil is to be main raw material and a kind of environment friendly biological fuel newly developed with methyl alcohol; Can store at normal temperatures and pressures, transport, use, plain metal or plastic containers can be stored; Detect through national quality testing department, and use through pilot conversion, its technical feature and safety index meet the requirement of country to domestic fuel, are a kind of ideal green environment-friendly fuels.If utilize sewer oil to prepare biological alcohol oil, not only make legal, the utilization more effectively of sewer oil ability, and sewer oil still prepares the high quality raw material of biological alcohol oil.
Summary of the invention
In order to make legal, the utilization more effectively of sewer oil, the present invention proposes a kind of technology of utilizing the sewer oil resultant to prepare the preferable biological alcohol oil of combustionproperty.
A kind of biological alcohol oil by the preparation of sewer oil resultant; It is characterized in that this biological alcohol oil is by weight than by the sewer oil resultant; Be that 3 ~ 35 parts of emulsifying agents and water fully stir the formation emulsions for 2 ~ 25 parts, leave standstill after 10 ~ 24 hours to mix for 40 ~ 95 parts with methyl alcohol again, leave standstill formation in 4 ~ 8 hours; Wherein, the sewer oil resultant is a kind of sewer oil to be removed the emulsifying agent that the stearin that obtains behind moisture and the impurity and tripalmitin obtain through saponification.
Described stearin and tripalmitin are to obtain through following method:
It is an amount of to get sewer oil, boils after-filtration, and the liquid after the filtration distributes fluid with shunting after cooling; In the container of then fluid being added a cover; 400 ~ 700 ℃ of following carbonizing treatment, cooled and filtered, gained filtrating is stearin and palmitate glyceride mixture.
Described sewer oil can filter out bigger solid impurity earlier in the process of heating, remain less impurity and filtered liq, also contains less impurity and moisture in this filtered liq; Therefore need to extract fluid after the shunting; Moisture is abandoned it, and also containing less impurity in the fluid of this moment can't separate, and therefore need further carry out carbonizing treatment; Form throw out and it is removed, can guarantee that like this content of stearin and palmitate glyceride mixture reaches 95% in this filtrating through filtering.
The saponification process of said stearin and tripalmitin is:
Boiled 30 ~ 60 minutes for 4～14 parts than getting 70～90 parts of stearin and palmitate glyceride mixtures, sodium hydroxide or 6 ~ 16 parts in yellow soda ash and water by weight, in boiling part, slowly stir.
Through saponification reaction, stearin and palmitate glyceryl ester generate StNa, sodium palmitate and glycerine under the highly basic effect of sodium hydroxide or yellow soda ash, and it is yellow powder that its saponification forms thing.
Described sewer oil resultant emulsifying agent and water can dissolve the formation emulsified soln, and this emulsified soln and methyl alcohol all belong to polar material, are the mixing liquids that can dissolve each other.
Biological alcohol oil of the present invention is made up of sewer oil resultant, first alcohol and water, and wherein the sewer oil resultant is not only outstanding emulsifying agent, and itself still is high performance fuel.China's application number is that the patent of CN201110274634.2 discloses a kind of environment-friendly energy-saving biological alcohol oil patent, the minimum combustion heat value that needs methyl alcohol just can reach 8600 kilocalories/kg more than 75% in this patent; And the biological alcohol oil of this patent; Only need methyl alcohol 40% under the minimum situation; Saved the consumption of methyl alcohol greatly; Because the fuel value of the 35% sewer oil resultant that is used can be up to 9000 kilocalories/kg, greater than the fuel value of methyl alcohol, therefore methanol fuel of the present invention is higher than the disclosed methanol fuel efficient of this patent in addition.
Biological alcohol oil stable performance of the present invention, not volatile, condensation point for-90 ℃, not spontaneous combustion, ignition temperature greater than 200 ℃, no pressure, do not explode, accidental ignition water waters promptly and goes out.The burning of this product is nontoxic, it is harmless to use, free from extraneous odour, no flue dust, is reproducible biomass new forms of energy, and monitoring meets national regulation through relevant departments.
Because this biological alcohol oil fuel value can reach 5100 ~ 9000 kilocalories/kg; Therefore of many uses, can directly substitute family, shop, chafing dish restaurant, hotel, hotel, unit dining room, steam boiler and medium and small industrial combustion, Baoshang, cooking that diesel oil, liquefied gas, piped gas, Sweet natural gas is widely used in city and rural area, cook.
It is raw material that this biological alcohol oil adopts sewer oil resultant, not only has good burning performance and cheap, and food safety threatens, avoids the sewer oil environmental pollution, to reduce aspects such as consumption of fossil fuels all significant reducing.
