Embodiment
Below in conjunction with specific embodiment the present invention is carried out detailed explaining.With reference to Fig. 1, shown large supercharged two-stroke explosive motor is generally by reference character 1 expression.Motor 1 has a pressurized air receiver 2 and a waste gas receiver 3, belongs to the firing chamber by the outlet valve of reference character 4 indications.Motor can for example can be used as be on the ship master motor or as being the stationary engine that starts generator in power station.Total output work of motor for example, is a scope from 5,000 to 70,000KW, but the present invention can be used in output work, for example, is 1, in the four stroke engine of 000KW.
Pressurized air fills into the air purification part of independent cylinder from pressurized air receiver 2.When outlet valve 4 was opened, exhaust flow passed waste gas duct and arrives waste gas receiver 3 and pass the turbine 6 that a traditional waste gas duct 5 arrives a turbosupercharger inwards, discharged by exhaust manifolds 7 from exhaust flow here.By an axle 8, turbine 6 drives a compressor 9, and compressor 9 is supplied air by an air inlet 10.The air that enters can enter air heater 33 by one and heat, and preferably uses a kind of waste heat source, and for example, cooling liquid comes the air that enters is heated.Compressor 9 is sent to a pressurized air conduit 11 with the pressurized air of atomizing, and pressurized air conduit 11 is passed into pressurized air receiver 2.
Suction air in the conduit 11 passes a humidifying unit 12, and humidifying unit 12 has three sprayer section 13-15 in illustrated embodiment.In first section 13, heat the water of available run-of-the-mill, as seawater, pass a plurality of roses that a pipe 17 arrives humidification and purified gases.For suitable excessive water is arranged, there is not particulate like this: from gas, be settled out as the salt in the water or other impurity.In second section 14, the water of supplying with by a pipe 18 is atomized in pressurized air.Same, in the 3rd section 15, the fresh water of supplying with by a pipe 19 is atomized in pressurized air.The temperature of the water of supplying with in each section is controlled according to the required temperature and humidity of pressurized air.The end of each section 13,14,15 comprises a drip collector, and described drip collector separation is suspended in the drop in the gas and contains from the pollutant in the pressurized air.Can be in cooler use section still less.The quantity of section in other thing, adapts with the output of motor.
Supply with the seawater and the fresh water of rose, utilize the thermal source of a kind of " discarding " to cool off or heat by a thermoconverter 34.The thermal source of " discarding " can, for example, be engine cooling water 35.In addition, the water of supplying with humidifying unit 12 can utilize waste gas to come preheating by a thermoconverter 38, as shown in Figure 2.The feature of heat exchanger can be selected, thereby makes the water vapour in the waste gas concentrate, and therefore can be recovered.
Leaving the absolute humidity and the temperature of the pressurized air of humidifying unit can pass through to control the temperature of the water in each section 13,14,15 of supplying with in the humidifying unit 12 respectively and/or control the temperature that enters air by a heater 33 and control.
In the outlet of flusher 12, the temperature of air is measured by battery 39, and sends a signal to the control unit (not shown).Control unit compares the temperature that records and the temperature of required (presetting).Do not conform to the value of being scheduled to if leave the temperature of the air of flusher 12, in order to eliminate the temperature difference, control unit is regulated the temperature of the water of the different sections that are supplied to flusher 12.
The temperature of the water of supply nozzle is controlled, works as pressurized air like this and leaves the absolute humidity that humidifying unit just can obtain the humidity of required air.In order to realize required engine operating status, select required value according to environment, it can, for example, be the absolute humidity of the maximum of pressurized air, or be added in the minimum thermal load on the motor, or be positioned between the two.
The air of humidification passes an auxiliary gas fan 16 that is driven by a motor 20, and with the charge air flow supercharging, and the cylinder that passes motor transmits waste gas duct 5 under local load's state, and waste gas duct 5 leads to the turbine 6 of turbosupercharger.A conduit 24 comes out from waste gas duct 5 top sets of the upstream of turbine 6.Described conduit 24 links to each other with the auxiliary turbine 26 of a driving generator 27.Therefore the energy of supplying with exhaust flow is transformed into electric energy, for example, has the energy of high radiation instinct.The amount of the waste gas that comes out from the shunting of auxiliary turbine 26 may be regulated by a changeable flow regulator 25 that is positioned at conduit 24.
Another kind of form, auxiliary turbine 26 (not shown) that can link to each other with a hydraulic pamp.(not shown) in other form, the gas fan 30 that auxiliary turbine 26 drives in the exhaust gas recirculation conduit 28.
Auxiliary turbine can replace with the energy consumption body of the gas-powered of other form, for example, and any positive displacement or on-positive displacement machine or motor.
According to another preferred embodiment shown in Figure 3, motor uses EGR gas.A recycling pipe 28 comes out from waste gas duct 5 top sets, and link to each other with pressurized air conduit 11, therefore, recycling pipe forms a recirculation line with the part of intake system, and intake system is the downstream of the attachment portion of the conduit 28 that links to each other with conduit 11.
A flusher 29 is inserted in the recycling pipe 28, comes water humidification and purifying waste gas.Warm water is supplied with flusher 29 from heat exchanger 34.The gas that comes out from flusher 29 leads to a gas fan 30 that is driven by a motor 31.Even waste gas turns in the high pressure side of turbine 6, gas fan 30 is necessary for these waste gas superchargings, reaches the high stress level of pressure than the pressurized air in the conduit 11.Although have pressure ratio between the suction side of motor and the discharge side, gas fan 30 makes recirculation become possibility, this means that recirculation all may be carried out under any required engine load.The waste gas of recirculation can, as shown in the figure, be directed into humidifying unit 12 the upstream conduit 11 or may be directed to the conduit 11 in the downstream of humidifying unit 12 (not shown)s.
If the waste gas of recirculation is directed into the upstream of humidifying unit 12,, just may uses and coming to partially absorb at least EGR gas at a high speed from the pressurized air of compressor by use spraying and the Venturi tube effect.In this case, there is not or have only a little waste gas gas fan just may realize the recirculation of waste gas.
Replace atomizing humidifying performance unit 12,29, can use a humidifying unit that comprises at least one tank 40,41 (as shown in Figure 5), waste gas becomes bubble by it.It also has an advantage, and the water in tank also can play the effect of noise barrier.In the required warm relatively temperature range of relative cold-peace that is positioned at, heat exchanger 34 is that such tank 40,41 supplies water.Humidifying unit 12,29 can have one or more sections, and this depends on the purifying and the humidification degree of waste gas, and humidifying unit 12,29 can combine with a plurality of atomizing humidifying performances unit.
Example 1

Motor turns round under 100% load, and the temperature of surrounding atmosphere is 25 ℃, and relative moisture is 30%, this means that sucking air will comprise about 6g water/kg air.The air consumption of motor is approximately 55kg/s.Through behind the compressor 9, the temperature of air is T1=190 ℃, and relative moisture is 0.25%.
In first humidifying segment 13, be approximately the water of supplying with the flow of rose 13l/s under 70 ℃ the temperature.Preferably the energy (promptly radiating the low energy of instinct) by using " discarding " is as engine coolant, and the energy of engine exhaust or other " discarding " obtains the temperature of desired water.Air wetting is 90% when above to relative moisture, is 85 ℃ in dry temperature, waits until that like this air absolute humidity is 110g/kg.When the air of emitting from first section of washing away, airborne salinity major part is purified.
In second humidification and the section of washing away 14, the fresh water by rose ejection 50l/s in temperature is 100 to 150 ℃ scope (preferably by in the use waste gas " discard " and energy obtain).The temperature of air remains on about 85 ℃, and therefore 100% humidity-full absolute humidity that closes air is about 120g water/kg air.
If in conduit 28, use an independent flusher 29 to come the waste gas of purifying recirculation proper, in purifying, the waste gas humidification is arrived about 100% relative moisture, temperature is approximately 110 ℃.
The temperature of leaving the air of flusher is approximately 85 ℃, and absolute humidity is 120g/kg.With traditional temperature be 37 ℃, absolute humidity is that the pressurized air of 6g/kg is compared, this can cause that the energy that is included in the exhaust flow increases by 30%, this correspondingly increases 16500KW for motor of selecting.This traditional 16500KW makes 16% exhaust flow to shunt from waste gas duct 5, and is sent to auxiliary turbine 26.Other all condition is identical, will use the energy of same amount with the form of fuel in traditional motor.Therefore, when the extra power of the energy input 1675KW that assists turbine to be increased slightly, can cause that oil consumption rate (SFOC) increases by 4%.
Example 2
This example has shown selects the possibility of the operating condition of motor under the situation of the low thermal force of motor.With the condition of as above identical ambient condition and engine load under, it is 30 ℃ that rose in first section of washing away 12 is supplied with temperature, flow is at least the seawater of 20l/s, therefore, change the temperature of pressurized air to being approximately T1=75 ℃ by evaporation, humidification is approximately 90% to relative temperature, and absolute humidity reaches the level of about 65g/kg.
In second section of washing away 13, supplying with has temperature to be approximately 30 ℃, and flow is the water of 60l/s.This is cooled to temperature with pressurized air and is approximately 37 ℃, is approximately 11g/kg at the 100% full absolute humidity that closes the air under the gas.
Therefore, can realize that the low thermal force of motor is set, for example, be used in when the heat overload signal of motor occurring.
Example 3
This example has shown that at motor be the possibility that middle heat is selected the operating condition of motor when carrying.With the condition of as above identical ambient condition and engine load under, it is 50 ℃ that the rose in the first flusher section 12 is supplied with temperature, flow is approximately the seawater of 13l/s.This temperature change with pressurized air is arrived about 75 ℃, and pressurized air is arrived about 80% relative moisture by humidification simultaneously.Therefore kelvin temperature reach the level of about 59g/kg.
In the second flusher section 13, supplying with has temperature to be approximately 76 ℃, and flow is the water of 50l/s.This to being approximately 75 ℃, is approximately 76g/kg at the 100% full absolute humidity that closes the air under the gas with the temperature change of pressurized air.
Therefore, can realize that the middle thermal force of motor is set, motor is reducing that NOx distributes and the amount of the energy that shunting is come out from exhaust flow is less than under the situation of the amount in the example 1 and can turns round.
