Abstract
A diesel engine air inletting and humidifying experiment device is composed of three chambers, that is to say, a float chamber, a water vapor generating chamber and a buffer chamber. The bottoms of the float chamber and the water vapor generating chamber are communicated through holes, a float-controlled valve, which can be freely adjusted up and down, is arranged inside the float chamber, a guide plate is arranged on the upper part of the float chamber, the air enters from slits of a glass cover plate above the float chamber and a box body, and slowly flows into the upper part of the water vapor generating chamber through the guide plate on the upper part of the float chamber, splash-blocking plates are arranged on the upper side of the water vapor generating chamber, and the air-inletting tube of a generator is directly arranged on one side of the buffer chamber. The effect of supersonic wave atomized water is far better than the working medium humidification quality controlled by the method of combining a water pump with a flow meter, and the accurate metering of the atomized water quantity can be effectively realized through controlling an atomization head independent switch.
Description
Technical field
The utility model relates to a kind of experimental provision of air inlet humidification reduction of discharging of internal combustion engine, specifically, is the experimental provision that reduces discharging NOx about the ultrasonic atomization air inlet humidification of diesel engine.
Background technology
The common method that the fuel of internal combustion engine water mixing reduces discharging has directly to spray water in fuel emulsification, firing chamber, three kinds of inlet air humidifications.
Fuel emulsification belongs to the static emulsion technology, though the fuel oil fuel economy after the emulsification is fine, its preparation process often cost is very high; Employing usually will be to the big change of making comparisons of the structure of internal combustion engine to the direct water spray in firing chamber, and the atomizing effect of injection flow rate, water is all not ideal enough; The inlet air humidification is promptly air to be carried out humidification before air enters draft tube, and the structure of internal combustion engine does not need to change like this, simultaneously, can realize the control of different amount of water at different operating modes outside machine, realizes good NOx emission reduction effect.
Existing air inlet damping device adopts water pump to control the amount and the working medium quality of humidification in conjunction with flowmeter more, and the water yield control of these class methods and the atomizing effect of working medium are all undesirable.
Summary of the invention
The purpose of this utility model is water yield control and the unfavorable shortcoming of working medium atomizing effect that overcomes existing air inlet air-humidification method, and a kind of device that uses bull ultrasonic atomization air inlet humidification is provided.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: diesel engine intake humidification experimental provision is made up of three chambers, be respectively float chamber, steam generation chamber and surge chamber, wherein float chamber links to each other with aperture with steam generation chamber bottom.But the float-actuated valve that easy on and off is regulated is installed in the float chamber, and fair water fin is set at an upper portion thereof; The steam that the steam generation chamber is consumed comes supply by the aperture of steam generation chamber and float chamber bottom, and the water of float chamber is replenished by float-actuated valve by the peripheral hardware water replanishing device, to keep liquid level that atomising head is required in the steam generation chamber; The draft tube of engine is directly installed on surge chamber one side.
Laying several ultrasonic atomization heads in the steam generation chamber, each atomising head is respectively equipped with independent switch, by external direct supply control.In diesel engine when work,, the specification that enters quantity that the steam vapour amount of diesel engine can be by adjusting ultrasonic atomization head in the steam generation chamber and atomising head is controlled the humidification degree of working medium.Also be provided with resistance on the top of steam generation chamber and spatter plate, take away the liquid water droplets that the atomizing water column splashes to prevent that air-intake negative-pressure from taking out.Air enters from the glass cover-plate of float chamber top and the slit of casing, fair water fin through float chamber top relaxes and flow to steam generation chamber top, rely on air-intake negative-pressure to take away the water vapor that the steam generation chamber produces, after the surge chamber buffering, enter the diesel engine intake pipe by pipeline.Diesel engine intake humidification experimental provision integral arrangement is convenient to observe at any time working condition in transparent casing.
In addition, this device can also be adjusted the humidification degree of air inlet at the different capacity engine by the method for changing atomising head.
The beneficial effects of the utility model are: the effect of ultrasonic atomization water is much better than the working medium humidification quality of water pump in conjunction with the control of the method for flowmeter, simultaneously, sees through control to the atomising head independent switch can realize effectively the atomizing accurate measurement of the water yield.

Embodiment
Determine the quantity and the specification of atomising head according to the maximum amount of water of engine test plan adding.During concrete the experiment, adjust the working quantity of atomising head as required.The duty of atomising head is controlled by the single channel power switch.In conjunction with Fig. 1 and Fig. 2 specific embodiments is done the utility model and to be described in further detail:
Air inlet fair water fin 1 is fixed on casing 5, glass cover-plate 3 covers casing 5 tops, plate 2 is spattered in resistance and float-actuated valve 11 mistake supports are fixed on the casing side, atomising head 9 is fixed in steam generation chamber bottom by atomising head support 7, atomising head 9 each power lead 16 are connected on the 24V direct supply 14 by branch switch 15, and branch switch 15 can be controlled the duty of each atomising head separately.
Produce air-intake negative-pressure during diesel motor work, with the space suction casing 5 of extraneous air by glass cover-plate 3 and casing 5, through flowing to steam generation chamber 8 tops gently behind air inlet fair water fin 1 water conservancy diversion, take away the steam that ultrasonic atomization head 9 produces, after surge chamber 6 bufferings, directly entered diesel engine by pipeline by working medium even, fully humidification.
