Micro-emission energy-saving engine master device recycling heat of tail gas by regenerative porous medium

Abstract

The invention discloses a micro-emission energy-saving engine master device recycling heat of tail gas by regenerative porous medium. The micro-emission energy-saving engine master device comprises an air cylinder, a piston, a tail gas inlet pipe, a tail gas discharge pipe, an air inlet pipe, an air filter, an engine gas inlet pipe and a silencer. A same elongated pipe in separated porous medium heat accumulators at a cold end and a hot end are in quick low-temperature and high-temperature heat exchange. An inner pipe porous medium waste heat recycling accumulator pipe and an inner-layer porous medium accumulator are arranged in the middle of a section from a high-temperature tail gas input pipe and a low-temperature waste gas discharge pipe. An outer pipe porous medium waste heat recycling heat accumulator pipe and an outer-layer porous medium accumulator are arranged in the middle of a section from a fresh low-temperature air input pipe to a high-temperature air introducing engine gas input pipe, a high-temperature burning and ash removing electric heating rod is arranged in the middle of the inner pipe porous medium waste heat recycling accumulator pipe, and a standby auxiliary gas compressor is arranged at an output end of the fresh low-temperature air input pipe. The micro-emission energy-saving engine master device recycling heat of tail gas by regenerative porous medium is applicable to an energy-saving engine.

Description

Technical field [0001] The invention relates to an uninterrupted heat-storage porous medium regenerator that uses high-temperature air to generate energy from the exhaust gas into the high-temperature air combustion technology of the engine to recover the heat energy of the engine exhaust gas, and can greatly reduce pollutants such as carbon dioxide and nitrogen oxides in the exhaust gas. The invention relates to a novel engine combination energy-saving device capable of greatly increasing output power through high-temperature and low-oxygen combustion, in particular to a regenerative porous medium tail gas heat energy recovery micro-emission energy-saving engine main component device. Background technique [0002] In the internal combustion engine, about 20% to 45% of the fuel heat taken away by the exhaust gas is completely wasted in vain and seriously pollutes the atmospheric environment. At present, the engine technologies of existing exhaust heat energy recovery devices...
