Engine vapor recycle and photolysis duplex combustion energy conservation and emission reduction method and device

Abstract

The invention relates to an engine vapor recycle and photolysis duplex combustion energy conservation and emission reduction method and device, and belongs to the field of engine energy conservation and environment protection. An existing engine exhaust system has the defects that energy consumption and emission are high, pollution to the environment is serious, and engine noise is large. According to the engine vapor recycle and photolysis duplex combustion energy conservation and emission reduction method and device, a heat absorber is arranged in an exhaust branch pipe, a Y-pipe is arranged on an air inlet pipe of an engine, and one port of the Y-pipe is connected with the heat absorber. When the engine exhausts air, vapor in tail gas is heated again by using the heat absorbing function of the heat absorber, the exhaust gas is driven to pass through the engine, enter a combustion chamber and be combusted again in a photolysis mode together, the vapor and the heat energy can be utilized in a duplex mode, and thus energy consumption of the engine is reduced effectively. Meanwhile, tail gas emission is reduced greatly, the emission of the engine can reach the national standard VI and the national standard VII, emission reduction reaches more than 80% when the engine is in an idle mode, and the effects of energy conservation, consumption reduction and emission reduction are truly achieved.

Description

technical field [0001] The invention belongs to the field of engine energy saving and emission reduction, and in particular relates to a method and device for energy saving and emission reduction of engine water vapor photolysis complex combustion. Background technique [0002] Water energy is an inexhaustible resource in nature that can be continuously regenerated, continuously utilized, and inexhaustible. In 2008, scientists around the world successfully researched in Iceland and found that water can be decomposed by light to produce hydrogen, and oxygen can be burned to generate water. It is a harmless and very clean energy source. With the continuous advancement of science and technology, the mystery of photolysis of water has been continuously uncovered. [0003] At present, the energy utilization rate of the engine (internal combustion engine) is only 20%. [0004] The principle of the existing engine (internal combustion engine) exhaust system is: install an exhau...

AI Technical Summary

Problems solved by technology

[0004] The principle of the existing engine (internal combustion engine) exhaust system is: install an exhaust pipe on the engine, connect it with the exhaust branch pipe, and install a muffler at the end of the exhaust branch pipe; when the engine is working, gas or fuel oil enters the engine combustion chamber to explode The exhaust gas generated in the end is dissipated through the exhaust pipe, the exhaust branch pipe and the muffler's own heat absorption function, and the waste heat and exhaust gas are discharged from the outlet of the muffler, causing relatively loud noise, and the incompletely burned exhaust gas contains a large amount of toxic and harmful substances. Substances can seriously pollute the air, especially when the car is parked and idling, the fuel or gas is severely incompletely burned, resulting in more serious energy waste and environmental pollution

[0005] At present, gas or fuel oil enters the combustion chamber of the engine for explosive combustion, during which a light source will be generated, which can photolyze part of the water vapor, and the photolysis of water vapor will produce combustible gas, which will directly enter the exhaust gas discharge system and be discharged into the atmosphere, which will cause energy waste of
