Cyclone 4 be placed in the front end in the hollow channel 21 (below will close to one end of Diesel Engine Exhaust Pipe be known as before,
Close on silencer one end be known as after or tail, in being known as between front and back；Axis side will be closed on along 21 radial direction of hollow channel
In referred to as, it is known as far from axis side outer), it is made of baffle 41 and swirl vane 42.
1) baffle 41
As shown in Figs 1-4, baffle 41 is mainly used for support swirl vane 42 and plays a supportive role to it, by stainless
Steel, titanium or other carbon steel materials are made.
The shape of baffle 41 is column axially extending along hollow channel 21 and with hollow cavity, during outer diameter is less than
The diameter in empty channel 21, difference depend on whether that Diesel Engine Exhaust Pipe smooth in exhaust can be made to determine, are vented when obstruction occurs
When the flowing of body, then the outer diameter for reducing baffle 41 is needed.
The air velocity of the exhaust gas 6 that the axial length of baffle 41 is discharged according to Diesel Engine Exhaust Pipe is determined, when exhaust gas 6
When air velocity is higher, the length of baffle 41 can be lengthened suitably, the purpose is to improve the stability of the cyclone 4, further
, it can also be by adding the locating rack 44 of long rod in 41 tail end of baffle to improve the stability of the cyclone 4 again.
When installation, the inner end of locating rack 44 is fixed on baffle 41, and outer end is fixed on the inner wall of hollow channel 21,
Locating rack 44 can be one and extend radially through supporting rod or two sections of difference on the baffle 41 along baffle 41
The supporting rod being fixed between 21 inner wall of baffle 41 and hollow channel.
Locating rack 44 is made of stainless steel, titanium or other carbon steel materials, is solid cylinder, and diameter preferably exists
5mm-20mm。
The shape of the preferred baffle of the present invention 41 is cylinder, and outer diameter is in 50-200mm, and axial length is in 300-
The thickness of 2000mm, shell 2 are 1-10mm.
In order to reduce 6 gas-flow resistance of exhaust gas, kuppe 45, the water conservancy diversion is arranged in the present invention in the front end surface of baffle 41
The shape of cover 45 is spherical crown shape, hollow cone shape or hollow pyramid-shaped, can smoothly guide the exhaust gas 6 along 41 outer wall of baffle
Flow and also can avoid the noise that the exhaust gas 6 is generated when impacting baffle 41.
Bottom surface outer diameter, 2 thickness of shell of kuppe 45 are identical as the outer diameter of baffle 41,2 thickness of shell respectively.
In order to reduce the resistance of exhaust gas 6, the tail bone of a hollow cylindrical or hollow taper is added in the tail portion of baffle 41
46, which can be the separating component to fix as one with baffle 41, or the portion being one of the forming with baffle 41
Point, set that there are one the exhaust hole that is communicated with the hollow cavity of baffle 41, the effects of the aperture on the rear end face of tail bone 46
It is to be discharged the expanding gas in the hollow cavity of baffle 41, to avoid baffle after baffle 41 heats up suddenly
41 dilatancies.
The shape of tail bone 46 can determine according to the requirement of aerodynamic quality (such as air velocity), aerodynamic quality requirement
The higher tail bone 46 (as shown in Figure 3) that bullet may be selected (i.e. when 6 air velocity of exhaust gas of diesel engine discharge is higher).
When needing that the tail bone 46 is arranged on baffle 41, also the locating rack 44 can be mounted on the tail bone 46
Between the inner wall of hollow channel 21.
2) swirl vane 42
Be made of stainless steel, titanium or other carbon steel materials, the quantity of swirl vane 42 can according to the size of silencer come
It determines, generally 3-12 pieces (as shown in Figure 5), blade shape have several forms and its size value (as shown in Figure 6).
Swirl vane 42 is fixed in the leading portion of the baffle 41 and is arranged along 41 periphery wall uniform intervals of baffle.
In the case where being provided with kuppe 45, the bottom surface setting of kuppe 45 is close in the front end of swirl vane 42.
The shape of every swirl vane 42 is blade-shaped, including four sides, respectively inner side edge 421, outer side edges 422, outer
Side trailing edge 423 and backside 424.
The inner side edge 421 and outer side edges 422 of swirl vane 42 can be arcuate or linear.Swirl vane 42 is radially-wide
Degree gradually increases from front to back, and inner side edge 421 is fixed on baffle 41, and outer side edges 422 are windward side, outside trailing edge
423 (the also referred to as tail ends of outer side edges 422) are affixed with the inner wall of hollow channel 21.It sees from front to back, all swirl vanes 42 enclose
The contours profiles of composition are taper type, and the taper of the taper type is in 18-25 degree, and cone height is in 50mm-200mm.
Formation airslide 43 between adjacent two panels swirl vane 42, i.e. diesel engine institute waste air 6 are along the airslide 43 by preceding
To rear flowing.Airslide 43 has following two structures：
1) linear type
42 axial length of swirl vane is shorter, is formed by airslide 43 to tilt the angles 15-30 with the axis of baffle 41
Gradient setting.
2) spiral line type
The axial length of swirl vane 42 is longer, is formed by airslide 43 to tilt 15-30 with the axis of baffle 41
Spend the gradient helix setting at angle.
The effect of swirl vane 42 is to form the airslide 43 of setting shape, when the high-speed flow of diesel engine institute waste air 6
After entering the airslide 43 in a manner of streamlined flow, by the air-flow of streamlined flow, gradually guiding is high speed rotation to the airslide 43
Air-flow, when high-speed rotating air-flow row to diversion column posterior segment, the flue dust in the high-speed flow is under the influence of centrifugal force
Detached and got rid of to the inner wall of hollow channel 21, when flue dust place of arrival just be ash-hole 31, then the part flue dust i.e. by
Ash-hole 31 enters in ash-collecting tube 3.
