Main part device of heat storage type porous medium tail gas heat energy recovery micro-emission energy-saving engine

Abstract

The invention discloses a main part device of a heat storage type porous medium tail gas heat energy recovery micro-emission energy-saving engine, which comprises a cylinder, a piston, a tail gas inlet pipe, a tail gas exhaust pipe, an air inlet pipe, an air filter, an engine gas inlet pipe and a silencer, wherein low-temperature and high-temperature exchange is carried out in the same long pipe in a porous medium heat retainer separated at a cold end and a heat end. An inner pipe porous medium residual heat recovery heat retainer pipe and an inner layer porous medium heat retainer are arranged on an intermediate channel from a high-temperature tail gas input pipe to a low-temperature residual gas exhaust pipe; an outer pipe porous medium residual heat recovery heat retainer pipe and an outer layer porous medium heat retainer are arranged on an intermediate channel from a fresh low-temperature air input pipe to a high-temperature air guide engine gas inlet input pipe; a high-temperature combustion ash clearing electric heating rod is arranged in an intermediate channel of the inner pipe porous medium residual heat recovery heat retainer pipe; and a standby auxiliary compressor is arranged at the output end of the fresh low-temperature air input pipe. The invention is suitable for being used on 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...
