Description
Technical field
The present invention relates to sewer oil recovery and utilization technology field, especially a kind of method taking sewer oil as raw material and make fuel for chafing dish.
Background technology
Along with China's rapid development of economy, the demand of the energy is increased rapidly, and China is the country of an energy scarcity, annual needs as the energy, and then make being developed in order to one of current economic transition, the Main Means changing economic growth for new forms of energy from a large amount of crude oil of external import.
Due to processing mode special of Chinese food, cause sewer oil product in the annual changing food waste of China up to more than 1,000 ten thousand tons, but this huge sewer oil resource is failed well to be developed, that annual being carried out by sewer oil a large amount of returns on dining table on the contrary, and then cause the concern of all circles, cause government and put into effect a large amount of behaves, and this usage behavior of sewer oil is forbidden and contained, and then also result in the cost up of social management; Meanwhile, this behavior returning dining table is returned the healthy of eater and is brought threat.For this reason, a large amount of measures preventing sewer oil from returning to dining table starts to occur.But these measures are only prevent sewer oil from returning dining table, but sewer oil can not be carried out Processing for removing, and then cause the discharge of a large amount of sewer oil to cause the pollution of environment, also make this rich in natural resources of sewer oil be not used and be wasted.
Based on this, also investigator is had to start the novelty teabag of sewer oil to study, invent a kind of ionic activity oxygen source head as one, Shanghai enviromental protection enterprise to go out oily deodorizing water-and-oil separator, high pressure is utilized to inject plasma activated oxygen in sewer oil, sewer oil is fissioned, forms the wetting ability such as tartrate, methyl alcohol degradation product, outflow with water, and then although the method solves the pollution that sewer oil brings to environment, causes this rich in natural resources of sewer oil and is wasted; So have again investigator to start sewer oil to be converted into biofuel, but its technique is comparatively complicated, tooling cost is higher; In Holland, sewer oil is processed into aviation fuels, but the cost of its obtained aviation fuels is higher, be 3 times more than of general aviation kerosene, and then it is higher to cause cost, is unfavorable for applying; And based on this, China is also used for the making field of aero oil in recent years to sewer oil, and successfully test successfully on board the aircraft.But, these sewer oil regenerations are all based on high-quality, the research in high energy consumption field, but study under the environment not based on family's demand for fuel, be unfavorable for the big area of sewer oil, recycle on a large scale, the accumulating amount causing sewer oil still cannot solve, and then is difficult to alleviate the harm that brings to environment of sewer oil; In fact, the demand of China's energy consumption is not only in space flight and aviation, and the demand of the inside such as industrial enterprise is also that demand is larger inside each family, peasant household.
For this reason, after sewer oil is carried out saponification process by this investigator, again it is further processed and be made into fuel, and then make the cost of manufacture of this fuel lower, manufacture craft is simple, the fuel made can be suitable for the demand of life fuel, reduce the energy consumption in people's life process, and sewer oil is recycled and is generalized to every family, a large amount of has reclaimed sewer oil, reduce the pollution rate that sewer oil brings to environment, and also have not been reported at present, sewer oil is used for the making field of fuel for chafing dish, and then provide a kind of new way for the regeneration of sewer oil.
