Fuel oil tank with external circulation filtering device and fuel oil engine

Abstract

The invention relates to a fuel oil tank with an external circulation filtering device and a fuel oil engine. The fuel oil tank with the external circulation filtering device comprises an oil tank body and a filtering device arranged outside the oil tank body, the filtering device comprises a hydraulic pump, a filter, an oil extraction pipe and an oil return pipe, and the oil extraction pipe and the oil return pipe are arranged on an oil tank shell; and fuel oil is sucked in from the oil tank body through the hydraulic pump and is filtered through the filter to be discharged to the oil tank body through the oil return pipe, and a filter element of the filter is a polyamide melt-blow filter element. When an oil product is polluted or every a certain time, the fuel oil in the oil tank body is circulated and filtered, so that pollutants, such as metallic oxide, separated-out colloid and asphaltene generated by long-time placement, in the oil product are eliminated; and meanwhile, when the oil tank is used for the engine, pollutant discharge of the engine can be reduced, fuel consumption is reduced, and faults of the engine are reduced. Meanwhile, when the engine does not work, the oil product is repeatedly purified, the quality of the oil product is guaranteed, the combustion efficiency of the engine is improved to the maximum degree, and pollutant discharge is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a fuel oil tank and a fuel engine with an external circulation filter device. Background technique [0002] Fuels include gasoline, diesel, ethanol gasoline, methanol gasoline, etc. During production, transportation and storage, a large amount of impurities will be produced and mixed, and clean fuels will also produce metal oxides, precipitated colloids, and asphaltenes after a period of storage. and other pollutants. Severely polluted fuel will cause wear and carbon deposits in the engine fuel injection system and combustion chamber, which will increase the fuel consumption of power equipment after a period of use, and the exhaust emissions will rise sharply, so cleaning treatment is required. [0003] The oil supply system on the existing engine is all equipped with a fuel filter, as disclosed in 2001, the Chinese patent "a new gasoline engine oil ...

AI Technical Summary

Problems solved by technology

These kinds of filter materials cannot meet the requirements of equipment for oil filtration in the industrial production process, resulting in problems such as high equipment failure rate, low operating efficiency, and shortened service life.
