Description
Technical field
The utility model relates to energy recovery and utilizes technical field, especially relates to a kind of boats and ships used heat and utilizes Π type stirling generator system.
Background technique
The heat that marine main engine fuel combustion produces only has small part acting, and all the other heat part systems of being cooled are taken away, and another major part is discharged into the atmosphere with exhaust mode, and exhaust loss accounts for total energy 40% left and right.Boats and ships install UTILIZATION OF VESIDUAL HEAT IN exhaust boiler additional; exhaust boiler is discharged fume 100-300 DEG C of left and right; boats and ships around ocean temperature are no more than 35 DEG C; this just forms a huge thermal gradient energy system; Stirling-electric hybrid (Stirling Engine) is the closed piston heat engine of a kind of external-burning (heating); have that fuel source is wide, efficiency is high, it is little to pollute, noise is low and the advantage such as easy to maintenance; as the power engine of clean and effective, significant to energy-saving and emission-reduction, protection of the environment in can applying in a lot of fields.
Stirling Engine is very strong to the adaptability of fuel, and the available energy, except coal, oil, rock gas, can also utilize the agriculture and forestry organic waste materials such as solar energy, atomic power, chemical energy and timber, the stalk heat energy of releasing that burns.The Stirling Engine thermal efficiency is high, and Stirling Engine cycle efficiency equals the Carnot efficiency under equal state in theory, and experiment shows that the actual effective efficiency of Stirling Engine can reach 32%～40%, reaches as high as 47%.Stirling Engine when operation pollutant emission is few, as external combustion engine fuel can be under enough air continuous burning, combustion ratio is more abundant, compared with internal-combustion engine, the harmful gas such as carbon monoxide and hydrocarbon of discharge greatly reduces.Stirling Engine does not have valve train, and the pressure of working medium in cylinder changes and approaches sinusoidal waveform, and burning can not produce pinking and exhaust ripple, thereby running is more steady, and noise is smaller.Stirling Engine running is more steady, and torque ratio is more even, and overload capacity is strong, and internal-combustion engine overload capacity only has 5%～15% by contrast.
Stirling Engine is simple in structure, and than the component of internal-combustion engine few 40%, only Packed cylinder and two pistons, do not have troublesome valve train, high pressure fuel injector system and need lubricated piston ring, keep in repair more convenient yet.

The measure that current ship energy saving reduces discharging is mainly that power and used heat utilization fall in boats and ships reduction of speed, main frame, used heat utilization comprises exhaust gas turbocharge, exhaust boiler, utilizes the desalination of sea water of main engine jacket cooling water, and the steam electric power producing about exhaust gas turbine generating, exhaust boiler is still in the feasibility study stage, on ship, also there is no practicality.Smoke evacuation after exhaust boiler will further utilize, and Stirling engine has advantage.Because ocean going vessel temperature of exhaust fume is at 100-300 DEG C, ocean going vessel exhaust smoke level is large, and ocean temperature generally can not exceed 35 DEG C, and therefore, between ship exhaust fume and seawater, thermal gradient energy density is large, meets Stirling engine job requirement.
In sum, for large-scale ocean going vessel, utilize the temperature difference system of himself, build used heat and utilize Stirling power generation system to become one of effective way of ship energy saving reduction of discharging.But, in prior art, lack the system that can realize above-mentioned purpose.

Working principle:
The helium of preliminary filling in heat absorber absorbs the used heat in ship exhaust fume, and after helium heat absorption, the acting of expanding in hot cylinder, promotes hot piston movement.In helium pressure compression process, the helium heat of compression is passed to seawater by cooler and is lost to marinely greatly, and its working principle can be described in detail by following 4 processes:
(1), isothermal compression process: the cold piston in compression chamber is in the time of lower dead center, and the hot piston in expansion chamber is at top dead center.Cold piston is moved to top dead center by lower dead center, and the hot piston in hot air cavity keeps motionless at top dead center.Helium is compressed in cold cylinder, and pressure and temperature increases.By the cooled with seawater effect of cooler, cold air cylinder temperature remains unchanged.When this process finishes, cold piston arrives half stroke, hot piston is in top dead center, and now, helium volume becomes minimum from maximum.
, (2) the appearance heating process such as: cold piston is continued to move toward top dead center from midstroke, hot piston is started to move to lower dead center by top dead center simultaneously, keep helium constancy of volume, helium is transferred to used heat adsorber (heater) by regenerator, absorb the heat of ship exhaust fume, temperature raises, and flows into hot cylinder.Because raising, realizes waiting under appearance condition helium temperature, so helium pressure increases.When this process finishes, hot piston arrives half stroke, cold piston arrives top dead center, now, helium pressure and temperature have all reached maximum value.
(3), isothermal expansion process: hot piston is continued to move to lower dead center by midstroke, and cold piston keeps motionless at top dead center.It is large that helium volume becomes, and pressure decreased absorbs the heat that used heat adsorber transmits simultaneously, and helium temperature remains unchanged.When this process finishes, hot piston arrives lower dead center, cold piston is in top dead center.The external outputting power of this process.
, (4) the appearance cooling procedure such as: hot piston is moved to top dead center by lower dead center, and meanwhile, cold piston is moved to lower dead center by top dead center.Because two pistons move simultaneously, keep helium constancy of volume.Helium returns to cold cylinder by regenerator.When helium passes through regenerator, heat passes to regenerator from helium, and helium temperature reduces inflow cold cylinder.When this process finishes, hot piston arrives top dead center, cold piston arrives lower dead center.Now, Temperature of Working pressure reaches minimum.
90 ° of the first Stirling engine and the second Stirling engine phase differences.
Operating process:
(1), system is while starting working, by the start button of control box, actuating motor obtains electric automatic starting, drives Stirling-electric hybrid crankshaft rotating, reach 30% rated speed after actuating motor auto-breaking deactivate.
(2), Π type Stirling engine makes helium expansion working by absorbing ship exhaust fume heat, compressed by cooled with seawater helium, realize isothermal compression → wait and hold the cooling closed cycle of appearance such as heating → isothermal expansion → wait, under flywheel moment of inertia promotes, ensure Π type Stirling engine continuous operation.
(3), after Π type Stirling engine starts successfully, the speed increaser that its output shaft connects closes row, drives permanent magnet generator running.
(4), S7-200PLC and the work of DEIF GPU monitoring whole system.
