Description
Technical field
The invention belongs to mechanical equipment technical field, be specifically related to a kind of large-scale diesel engine energy-saving and noise-reducing safety
System.
Background technology
The diesel engine that industrial circle uses, especially power at the large-scale diesel engine of more than 600KW,
Three aspect problems below all existing during use:
1) heat utilization rate is low, and supply and demand are unbalanced: the 30%-35% that general diesel engine produces heat energy is
Drain as waste gas, cause this partial heat not make full use of and waste；On the other hand, enter
The cooling water temperature of diesel engine cylinder block is many to aspire for stability more than 60 DEG C, needs substantial amounts of energy heats water
Temperature.Cold day underload operation, especially diesel engine unshielded by wind time, body operating temperature can be relatively low,
Work at this temperature for a long time, do not do any protection and can damage the power-equipment of diesel engines.
2) operating noise is big: the deficiency that diesel engine designs due to smoke exhaust pipe, causes local location easy
Produce gas swirl, hinder the discharge of gas, air flowing and the friction of smoke exhaust pipe cavity wall and then produce the biggest
Noise, allow people be difficult to stand.
3) electrostatic problem ratio is more prominent: diesel engine pipeline operationally can be because of liquid flowing and pipe friction
Produce electrostatic, and then sparking may be produced in the place that resistance is minimum, cause certain potential safety hazard.

Detailed description of the invention
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
The structure of apparatus of the present invention is, including Thermoregulation part, noise reduction part and eliminostatic mechanism 4
Three parts,
With reference to Fig. 1, Thermoregulation part is, including the heat pipe 2 of Guan Bi, a part for heat pipe 2
It is looped around exhaust emission tube road 6 outer surface, a part of ring of heat pipe 2 connected with diesel engine cylinder block 7
It is wound on oil-water pipeline 8 and the outer surface of water tank 9；
Being provided with flow control valve in heat pipe 2, flow control valve is connected with controller, flow-control
Valve forms heat conduction balanced controls 3 together with controller；Diesel engine cylinder block 7 opening's edge is provided with temperature sensing
The probe of device 5, temperature sensor 5 outfan passes through holding wire with the controller in heat conduction balanced controls 3
Connect.
Heat conduction balanced controls 3(contains temperature sensor 5), mainly control heat pipe by flow control valve
The speed of the velocity of medium in 2, it is achieved the effect of regulation heating (cooling), is improving heat utilization rate
While also play thermoregulator effect.
With reference to Fig. 1, noise reduction part is, at exhaust emission tube road 6(near exit position) be communicated with recessed
Male deafener 1.Lenticular deafener 1 uses variable cross-section concave-convex type profile, air inlet one end and diesel oil
The air vent of machine cylinder body 7 connects, and one end, gas outlet is connected with exhaust emission tube road 6.Lenticular deafener
1 causes acoustic impedance to change according to pipeline section sudden change, makes partial noise reflect, and then sound wave interferes,
Thus reduce outside radiated noise.
With reference to Fig. 2, Fig. 3, eliminostatic mechanism 4 is, eliminostatic mechanism 4 will on single pipeline
Adpting flange joint (or joint of joint) both sides short circuit, and at termination ground connection (PE)；Meanwhile,
Eliminostatic mechanism 4 uses annular to connect in whole pipe-line system and radioactivity connects the side combined
Formula, is integrally formed isoelectric level, simultaneously by terminal ground connection (PE).
Connect between the abutted flange of 1, No. 2 ends of fuel pipe of diesel engine and have shorting stub 10,
Connect between the abutted flange of 1, No. 2 ends of crude oil pipe and have shorting stub 10, at liquefaction gas pipe 1,2
Connecting between the abutted flange of number end has shorting stub 10, all of shorting stub 10 to use annular successively
Connected mode or the final ground connection of radial pattern connected mode, constitute the eliminostatic mechanism 4 that the present invention is total.
The operation principle of apparatus of the present invention is:
1) utilization efficiency of heat energy is improved.Based on heat conduction balanced controls 3, one is by temperature sensor 5,
It is built into cylinder body water inlet detection water temperature, and result is fed back to device body；Two is heat conduction balancing machine
The controller of structure 3, it is according to the flow velocity of the feedback control internal liquid medium of temperature sensor；Three is to lead
Heat pipe 2, a part for heat pipe 2 is wrapped in exhaust emission tube road 6 outer surface, passes through heat exchange method
It is applied to the heat circulation in waste gas heat in (cooling) system (absorption heat), heat pipe 2 simultaneously
Another part be wrapped in oil-water pipeline 8 and water tank 9 outer surface, the heat energy that will be obtained by endless form
It is applied to interior media and (release heat) is heated or cooled, be used for heating (or cooling) its interior media,
Ensure the temperature needed for normal work.
Owing to heat exchange is that a relative dynamic process is (when in heat pipe, medium temperature is higher than heated object
Time, it is the process of heating；When in heat pipe, medium temperature is less than heated object, it is the process of cooling),
So improving the thermoregulator effect that also plays while heat utilization rate: when heat pipe cross-sectional area and
When the temperature in exhaust emission tube road is certain value (or amplitude of variation is little), flow media in heat pipe
Temperature height be dependent on the speed of flow velocity: when the temperature is too low, this device just reduces flow velocity and improves
The temperature of heating (water tank and pipeline)；When temperature is too high, it just improve flow velocity reduce (water tank and
Pipeline) temperature.
2) noise is substantially eliminated.It can be seen from figure 1 that lenticular deafener 1 is concavo-convex the most alternate
Shape, the artificial pipeline section mutation content that increases, the structure of employing " lenticular deafener ", utilize sound
Sound propagation characteristic, i.e. pipeline section sudden change causes acoustic impedance to change, makes partial noise reflect, and then sound wave
Interfere, thus reduce outside radiated noise.
3) electrostatic accumulation is prevented.Move towards feature according to pipeline and electrical grounding net is set.At single pipeline
Upper employing shorting stub 10 is by flange both sides short circuit, and termination ground connection (PE) (referring to Fig. 2)；At pipe
Road system carries out annular connect and radioactivity connects the mode that combines, isoelectric level is made one whole
Body, guarantees earthing effect by certain Safety Redundancy, simultaneously by terminal ground connection (PE), it is ensured that no
Have static focus (referring to Fig. 3).Guarantee because of liquid flowing and pipe friction produced by electrostatic by time
Lead away, reduce unsafe risk.
The work process of apparatus of the present invention is, before starting diesel engine, first at diesel engine cylinder block exhaust opening
And between exhaust emission tube road 6, lenticular deafener 1 is connected, by heat pipe 2 and heat conduction balancing machine
Structure 3 puts in place according to (Fig. 1) connection, simultaneously according to diesel engine different model, by heat conduction balanced controls 3
Running parameter be arranged in preset range；According to pipe-line system, eliminostatic mechanism 4 is moved towards feature enter
Row annular connects and radioactivity connects the mode combined, and isoelectric level is integrally formed, simultaneously will eventually
Point ground connection (PE), finally, then completes Insulation monitoring and the ground connection of heat conduction balanced controls 3 of heat pipe 2
Detection, it is possible to employ.
Apparatus of the present invention, effective to all diesel engines, equally applicable to the machine using liquefaction gas.
