Background technique
Increasingly serious along with energy worsening shortages and environmental problem, the energy-saving and emission-reduction of internal-combustion engine are subject to common people and pay close attention to.Utilize organic Rankine bottoming cycle (ORC) technology reclaim diesel residual heat be current study hotspot, ORC thermal efficiency of cycle and Security higher, structure is simple.But the decomposition temperature of its working medium used requires lower than 350 DEG C, and I. C. engine exhaust temperature is generally up to 500 ~ 600 DEG C.Higher temperature likely can cause organic working medium to decompose, and this is the key point one of of restriction ORC in high-temperature exhaust air heat recovery.The waste heat supply temperature of cooling water of internal combustion engine is lower, but the quality of its heat utilization and efficiency are lower again, so recovery difficult is larger.
Turbocharging technology is the important technical improving engine performance, increasing combustion engine specific power, is utilized widely.But the installation that the problem brought is turbine will make the exhaust back pressure of internal-combustion engine raise, thus cause exhaust loss to become large, the output work of internal-combustion engine is declined to some extent.
For above-mentioned situation, if can propose one to utilize exhaust heat stage by stage, and drive the system of the gas compressor of internal-combustion engine with the energy reclaimed, then the raising of combustion motor energy-conserving and emission-cutting technology is significant.
Summary of the invention
The object of the invention is, propose a kind of system of internal-combustion engine steam supercharging heat recovery, organic Rankine bottoming cycle combines with thermo-electric generation and air intake pressurized technology by this system, reaches the object improving afterheat of IC engine reuse efficiency.
Below in conjunction with accompanying drawing principle of the present invention and system formed and be described.Internal-combustion engine steam supercharging residual neat recovering system, includes the gas compressors such as thermoelectric generator, circulating water pump, preheater, vaporizer, radiator, gas compressor, generator, decompressor, working medium pump and internal-combustion engine and turbine shaft connects and composes turbosupercharger.The technological scheme adopted is: internal combustion (IC) engine cylinder jacket water is by the high-temperature water side of the cold junction of pipeline and thermoelectric generator, decompressor, preheater and circulating water pump, and series winding forms cooling water heat and utilizes the circulatory system successively.Gas compressor in turbosupercharger sends into air-intake of combustion engine end to after air inlet compression, I. C. engine exhaust end and thermoelectric generator hot junction, vaporizer gas side, and serial connection forms and is vented heat utilization system successively.Turbo machine in the cryogenic fluid side of preheater, the working medium side of vaporizer, turbosupercharger, the working medium side of condenser and working medium pump, series winding forms organic rankine cycle system successively.Decompressor is connected with generator shaft.
The working principle of internal-combustion engine steam supercharging residual neat recovering system is: the exhaust of internal-combustion engine is introduced into thermoelectric generator, and utilize the temperature difference to produce electric energy, the exhaust after cooling is again as the driven by energy decompressor of organic rankine cycle system.The utilization of internal combustion engine cylinder jacket cooling water heat, mainly carries out preheating to (in organic Rankine bottoming cycle preheater) working medium.
Feature of the present invention and beneficial effect are that can break through the restriction of organic Rankine bottoming cycle for the temperature in the source of recovery, sublevel reclaims the waste heat energy of waste gas and cooling water, realizes the efficiency utilization of waste heat.When can also avoid low-load, exhaust energy is not enough to drive the situation of pressurization system to occur simultaneously, adds the scope that pressurization system effectively works.
