Method for preparing automobile power fuel from domestic garbage

Abstract

The invention discloses a method for preparing vehicle power fuel by using domestic waste, including an anaerobic fermentation process, a methane purification process, and a methane compression, storage and transportation process. The anaerobic fermentation process comprises: the domestic waste is filled to a wastebin and then injected with domestic sewage and sealed, and later the anaerobic fermentation is carried out for generating methane which is stored for preparation; the methane purification process comprises: the methane goes through a biological desulfurizing tower, a low-pressure carbon dioxide separator and a gas-water separator in sequence and then is treated by purification, and later is stored for preparation; and the methane compression, storage and transportation process comprises: multi-level compression is carried out on the purified methane, and later deep dehydrating and drying are carried out on the methane, and then the methane is transported to a gasholder for storage by a transportation pipeline and finally is added to an automobile for use by a pressurized gas station. The invention has simple process and easy operation, and takes domestic sewage as a fermentation catalyst for the realization of pollution control so as to provide novel green energy for the automobile, simultaneously and effectively avoid the pollution of the domestic waste to the environment and achieve pollution-free emission.

Description

technical field [0001] The invention relates to a method for preparing fuel, in particular to a method for preparing motor fuel for vehicles by using household garbage. Background technique [0002] With the development of the economy and the acceleration of urbanization, the amount of urban domestic waste in my country has increased rapidly, and there are a large amount of biomass waste in urban domestic waste, which is easy to biodegrade and high in water. The stench formed is solid waste pollution. The main source of pollution of the environment, due to the increasing amount of domestic garbage, the negative effects of garbage are becoming more and more obvious, and the disposal of garbage has become an urgent problem to be solved. [0003] Under the circumstances that the existing energy sources are becoming more and more tense and the call for reducing carbon dioxide emissions is getting louder and louder, as a vehicle that consumes a lot of energy and emits a lot of exh...

As a low-cost, non-polluting alternative energy source, biogas has attracted more and more attention. Most of the current biogas is self-produced and used by rural households, and it adopts the form of fluid fermentation, that is, human, poultry and livestock manure is used as fermentation raw material to produce biogas. , often referred to as artificial biogas, is used as a domestic fuel with a small range of use, and there has been no report on using biogas as a vehicle power fuel
