Description

Net formula purifying vehicle exhaust silencing apparatus

The utility model relates to purification plant, specifically net formula purifying vehicle exhaust silencing apparatus.

The harm that vehicle exhaust brings to people is a global difficult problem.The method of external solution vehicle exhaust problem is to add catalyzer or utilize the electronic technology at their tip to control fuel oil accurately before burning in the fuel oil of motor, to reach combustion efficiency absolutely.Both made like this, with high costs because the technology tip, it is all multifactor that condition limits or the like, also have only on the automobile of minute quantity and could use, and discharge capacity is big, and most of automobiles that black smoke is dense are inapplicable.And there are a lot of defectives in the automotive muffler that China uses at present, and function singleness can only be eliminated the noise, and exhaust is not smooth, resistance is big, and the temperature height is dangerous, can not the contaminated solution problem.Can solve the problem of the exhaust emissions noise elimination purification of most of automobiles effectively at the slurry formula automotive silencing purifier of first to file to this inventor, its deficiency one is in actual motion, because the temperature height that vehicle exhaust is discharged, slurry is not durable, and causes dry pulp will influence its purifying effect; The 2nd, because steam flow is too fast, the impeller in the purifier is again a high speed rotating, so poor durability; The 3rd, slurries are difficult to control, and purifying effect is poor at least, can be blown out by steam flow at most.

The purpose of this utility model is the deficiency that overcomes above-mentioned slurry formula automotive silencing purifier, and a kind of good purification is provided, and durable is easy to operate, the net formula purifying vehicle exhaust silencing apparatus that cost is low.

The utility model is achieved in that the formation of net formula purifying vehicle exhaust silencing apparatus is in the enclosure the movement gauze element to be housed, and the combustion-supporting layer of vacuum is arranged between movement and shell.

The movement two ends are the movable guide plates that have some apertures, and filter core two ends to import and export is provided with the multi-stage diffluence plate or is provided with the shunting inner cover.Reticulate filter core with groups of metal filaments.The shell profile is oval, and fluted.

Its working principle is: inertia absorption, filter hold back, secondary combustion, deposition are cleaned, soft netted shunting is eliminated the noise.The height of the size of exhaust airstream, temperature when it utilizes engine operation, filter core will shrink automatically, expand, and reaches with this to purify the black soot and guarantee the unimpeded purpose of exhaust.Because the gauze element that adopted material high temperature resistant, that the acid resistant alkali sound-absorbing effect is fabulous to make, the sound of the band High Temperature High Pressure drying that motor is discharged has carried out netted shunting to be handled, and the noise elimination effect obviously improves.

Net formula purifying vehicle exhaust silencing apparatus of the present utility model is because rational in infrastructure, the gauze element that is adopted, make its form the absorption of collection inertia, filter hold back, secondary combustion, deposition clean and be the multi-functional processing mode of one, and the effect of eliminating the noise is preferably arranged.Through repeatedly detecting repeatedly of environmental monitoring center, Yunnan Province, the result is that purifying effect is good.The utility model be collection except that black smoke, eliminated noise, hold back burning black carbon granules and be environmental protection new product the machine all over the body.Have simple in structurely, multiple functional, handsome in appearance, keep in repair easy to usely, cost is low, and adaptability is strong, characteristics such as long service life.

Among the figure, the 1-shell, the 2-movement, the 3-groove, the combustion-supporting layer of 4-vacuum, the movable guide plate of 5-, the 6-flow distribution plate, the 7-flow distribution plate, 8-shunts inner cover, 9-filter core.

Be depicted as embodiment's 1 of the present utility model structure as Fig. 1-5.Promptly in the movement 2 in the enclosure gauze element is housed, the movement two ends are movable guide plates 5, and filter core two ends to import and export is provided with two-stage shunting plate 6,7, and some apertures are arranged on the flow distribution plate.The combustion-supporting layer 4 of vacuum is arranged between movement and shell.Reticulate filter core with groups of metal filaments.The shell profile is oval, and fluted 3.

As Fig. 6-8 is embodiment's 2 of the present utility model structure.Profile and embodiment 1 slightly have any different, and the part flow arrangement in the shell is shunting inner cover 8, and covering in the shunting on the circumferential surface of the end in the shell has some apertures, and it is identical for all the other structures and embodiment 1.
