TECHNICAL FIELD

[0001] The present application relates to the technical field of civilian fuel, in particular to a civilian ether-based fuel. BACKGROUND

[0002] At present, civilian fuel mainly includes liquefied petroleum gas, natural gas and the like. Among them, the liquefied petroleum gas usually adopts high-pressure storage mode, and there are safety hazards such as high-pressure container leakage and explosion; during the combustion process of part of the civilian fuel, the problem of incomplete combustion is prone to occur, which leads to low thermal efficiency, and the components that are not fully combusted may cause energy waste; in addition, some fuels contain elements such as sulfur, nitrogen and phosphorus, and pollutants are prone to be generated after combustion, which does not meet the environmental protection requirements.

[0003] In order to solve the problems of insufficient safety, low combustion efficiency and poor environmental protection of the existing civilian fuel, the present application provides a new type of civilian ether-based fuel to improve the safety, combustion completeness and thermal efficiency of the civilian fuel. SUMMARY

[0004] In view of the problems existing in the prior art, the present application discloses a civilian ether-based fuel, which is mixed by carbon five and dimethyl ether; according to the weight percentage, the content of the carbon five is 10-30%, and the content of the dimethyl ether is 70-90%.

[0005] As a preferred technical scheme of the present application, the carbon five is a low-pressure flammable liquid and does not contain sulfur, nitrogen and phosphorus elements.

[0006] As a preferred technical scheme of the present application, the civilian ether-based fuel can be stored in a low-pressure steel barrel.

[0007] As a preferred technical scheme of the present application, the civilian ether-based fuel can generate "mixed empty light hydrocarbon gas" after being treated by a special gas generator, and the "mixed empty light hydrocarbon gas" is a saturated gas.

[0008] The present application also discloses a preparation method of the civilian ether-based fuel, which is characterized by comprising the following steps: carbon five and dimethyl ether are put into a mixing device in a proportion of 10-30% and 70-90% by weight percentage, and stirred and mixed at normal temperature and pressure until uniform, so as to obtain the civilian ether-based fuel.

[0009] The present application has the following beneficial effects: 1. The carbon five used in the present application is a low-pressure flammable liquid, and after being mixed with dimethyl ether, it can still be stored in a general low-pressure steel barrel, without the need for a high-pressure container, thereby reducing the risk of leakage and explosion; and the "mixed empty light hydrocarbon gas" generated by the special gas generator during combustion is a saturated gas, which is easy to mix with air and not easy to gather, thereby reducing the occurrence of critical accidents such as explosion or poisoning.

[0010] 2, "mixed air light hydrocarbon gas" is easy to mix with air, combustion is more complete, thermal efficiency is higher than natural gas and civilian liquefied gas, and energy utilization rate is improved.

[0011] 3, carbon five does not contain sulfur, nitrogen, phosphorus and other elements, and the combustion product of dimethyl ether is mainly carbon dioxide and water, so that the fuel of the application has low pollutant emission after combustion and is more environmentally friendly.

[0012] 4, the same as liquefied petroleum gas and natural gas, can be replaced with each other, without large-scale modification to existing civilian stoves, wide application range. DETAILED DESCRIPTION
