A method for making chafing dish fuel by using gutter oil as raw material

Abstract

The invention relates to the technical field of recycling of gutter oil, particularly to a method for producing hot pot fuel from the gutter oil used as a raw material. The gutter oil and sodium hydroxide have a reaction and are subjected to salting-out treatment, solids obtained through salting-out treatment are dissolved and react with sodium citrate, the hot pot fuel is produced, so that the gutter oil is recycled, and the environmental pollution is reduced; besides, raw materials in the treatment process are easy to obtain, the treatment technology is simple, and the producing cost is low; particularly, in the preparation process, distilled water replaces traditional tap water, accordingly, the yield of the fuel is increased, the quality of the fuel is improved, and the burning firepower of the fuel is guaranteed; particularly in combination with control on technological parameters in the preparation process, the gutter oil is optimized during production of the hot pot fuel, the yield of the hot pot fuel is increased, the quality of the hot pot fuel is improved, and the burning firepower of the hot pot fuel is improved.

Description

technical field [0001] The invention relates to the technical field of waste oil recovery and utilization, in particular to a method for making chafing dish fuel by using waste oil as a raw material. Background technique [0002] With the rapid development of my country's economy, the demand for energy is growing rapidly, but my country is a country with energy shortages. It needs to import a large amount of crude oil from abroad as energy every year, which makes the development of new energy become the current economic transformation. One of the main means of changing economic growth. [0003] Due to the special processing methods of Chinese dishes, the waste oil products in my country's kitchen waste are as high as 10 million tons or more every year. However, the huge waste oil resources have not been well developed and utilized. Instead, the waste oil is processed every year. A large number of them are returned to the dining table, which has aroused the attention of all wa...

However, these measures only prevent the waste oil from returning to the dining table, but cannot eliminate the waste oil, which leads to the discharge of a large amount of waste oil and causes environmental pollution. wasted

[0004] Based on this, some researchers have also begun to study the new uses of waste oil. For example, an environmental protection company in Shanghai invented a kind of ion active oxygen source to eliminate oil and deodorize oil-water separator, which uses high pressure to inject plasma active oxygen into the waste oil. The oil undergoes fission to form hydrophilic degradation products such as tartaric acid and methanol, which are lost with water. Although this method solves the environmental pollution caused by waste oil, it causes waste oil, a rich resource, to be wasted; Some researchers have begun to convert waste oil into biodiesel, but the process is relatively complicated and the processing cost is high; in the Netherlands, waste oil is processed into aviation fuel, but the cost of the obtained aviation fuel is relatively high, which is lower than that of general aviation kerosene. As much as 3 times, and then caused the higher cost, which is not conducive to popularization and application; and based on this, my country has also used waste oil in the field of aviation oil production in recent years, and has successfully tested it on aircraft

However, the recycling of these waste oils is based on research in high-quality, high-energy-consuming fields, but not based on the environment of household fuel demand, which is not conducive to the large-area and large-scale recycling of waste oil, resulting in the accumulation of waste oil The amount of waste oil still cannot be solved, and it is difficult to alleviate the harm caused by waste oil to the environment; in essence, the demand for energy consumption in my country is not only the demand in aerospace, industrial enterprises, etc., but also the demand in every family and farmer. larger

[0005] For this reason, the researcher saponified the gutter oil, and then further processed it into fuel, so that the production cost of the fuel is low, the production process is simple, and the produced fuel can meet the needs of domestic fuel. It reduces the energy consumption in people's living process, and promotes the recycling of waste oil to every household. A large amount of waste oil is recovered, which reduces the pollution rate of waste oil to the environment, and has not been reported yet. The use of waste oil in the production of hot pot fuel provides a new way for the recycling of waste oil
