Embodiment
Below in conjunction with accompanying drawing, describe preferred embodiment of the present invention in detail.
Fig. 2 is to the exemplary plot of silencer for automobile of the present invention shown in Figure 4.Present silencing apparatus shown in Figure 1, the exploded perspective view of silencer for automobile of the present invention shown in Figure 2, the sectional view of silencer for automobile user mode of the present invention shown in Figure 3, the rotary state of silencer for automobile swivel plate of the present invention shown in Figure 4.
Shown in above-mentioned figure, silencer for automobile 100 of the present invention comprises: casing 10, stationary axle 20, solid of rotation 30, aluminium net 60, copper mesh 70, static generation part 80, purifying part 90.
Solid of rotation 30 is columnar structured, the one end is open, solid of rotation 30 comprises: swivelling pipe 32, the other end is provided with stair-stepping joint 34, joint 34 is connected with the connecting tube cylindraceous 36 that diameter diminishes, the end of the outer wall of suction tude 12 inserts connecting tube 36, is connected by clutch shaft bearing 22 between the outer wall of suction tude 12 and cylindric connecting tube 36 inwalls; The tabular swivel plate 38 of a plurality of bendings is located at the inboard of joint 34 with the radiation shape; Backing plate 40 is circular, is connected in the end of a plurality of swivel plates 38, and the centre is provided with the hole, also is provided with taper shape on the backing plate 40 and dredges plate 42; Bearing housing 48 is connected in the centre of backing plate 40 inboards, and second bearing 44 and the 3rd bearing 45 dredged on plate 42 and the stationary axle 20 with taper shape combine, and bearing housing 48 is inserted in the hole of the centre of backing plate 40; Spirality is cut apart slide plate 50, is semicircle, is connected on the outer wall of bearing housing 48 with being radiation; Behind the tail gas process connecting tube 36 of suction tude 12 inflows, adjust direction with dredging plate 42 collisions, be able to and swivel plate 38 collisions, make swivel plate 38 rotations, cut apart slide plate 50 with swivel plate 38 collision back tail gas through above-mentioned a plurality of spiralitys, make and cut apart slide plate 50 rotations;
Purifying part 90 is cylindric, comprising: nickel screen supporting frame 92 is provided with compact arranged a plurality of perforation; A plurality of palladium catalysts 94 are ring-type dictyosomes, and around nickel screen supporting frame 92, the ring-type dictyosome contains the palladium particle; Stainless (steel) wire 96 is wrapped in nickel screen supporting frame 92 and platinum catalyst 94; Purifying part 90 be between solid of rotation 30 and aluminium net 60 along the inwall combination of casing 10, have a vent ability with netted, the tail gas of cutting apart slide plate 50 through spirality is passed through smoothly, tail gas by the time purifying harmful gas.
The working principle of silencer for automobile 100 with said structure is as follows:
At first, the tail gas in the 1 of automobile engine burning enters suction tude 12 through outlet pipe 3.
Tail gas by suction tude 12 flows into the connecting tube 36 that is connected with suction tude 12, contains harmful gas in the tail gas that flow into this moment, and is the state of high temperature, high pressure.
Tail gas by connecting tube 36 with dredge the collision of plate 42 rakes after abate the noise, adjust the direction of tail gas, bump with a plurality of swivel plates 38.At this moment, swivel plate 38 is a heeling condition, makes and the collision plane maximum of tail gas that swivel plate is rotated thus.
Therefore, rotate solid of rotation 38 with tail gas and swivel plate 38 collision backs that the high pressure and the condition of high temperature flow into, when swivel plate 38 rotates, the solid of rotation 30 that links together with swivel plate 38 and cut apart slide plate 50 and also rotate thereupon, thereby greatly reduce the pressure and temperature of tail gas, finally can obtain sufficient erasure effect.
Afterwards, with the tail gas that dies down after swivel plate 38 collision be almost stress-free state, tail gas is then along with the rotation that spirality is cut apart slide plate 50 keeps certain rotation status to be discharged.
The tail gas of cutting apart slide plate 50 through spirality is cut apart the direction rotation of slide plate 50 rotations along with spirality, the center is in pressure-less state, and and the static that produces at static generation part 80 combine, ion dissociation is included in the coal smoke of the corpuscular property object in the tail gas for the first time, flow in the lump in the purifying part 90.
The tail gas that flows into purifying part 90 is successively by platinum catalyst 94 and nickel screen supporting frame 92 time, and the influence that is subjected to two kinds of catalyzer will reduce harmful gas.
The static that produces with successively by aluminium net 60 and copper mesh 70 time through the tail gas of purifying part 90 combines, and ion dissociation for the second time takes place, resolving harmful gas, corpuscular property material process conversion process after outlet pipe 16 be discharged in the air.
The tail gas that is discharged into airborne conversion is can quantize discharge, other harmful gases in the air are produced activations, to help purifying air.
In order to confirm the performance of silencing apparatus of the present invention, following 2 tests have been carried out.
Test 1
Utilize the content of each coal smoke material in the exhaust measuring appliance measured automobiles tail gas, and contrast with the emission standard value of this material, its result is as shown in table 1 below.
Table 1
Car type: modern Sonata
Test 2
The corpuscular property coal smoke is measured test, corpuscular property amount of soot when measuring the silencing apparatus that uses on the current automobile respectively and the corpuscular property amount of soot when using silencing apparatus of the present invention, and each is measured 3 times, and its result is as shown in table 2 below.
Table 2
Car type: modern lorry light rail car (1.5t)
The present invention illustrates with reference to the embodiment shown in the accompanying drawing, but this is an example, and as can be known, from then on the personnel that have known technology in related domain can make various conversion and equal embodiment.Therefore, protection scope of the present invention should be as the criterion with the scope of claims.
