Abstract
The utility model discloses a tail gas decompression muffler which can decrease the tail gas pressure and meanwhile can reduce the noise. The muffler comprises a cylindraceous shell, an air inlet pipe, a filter plate. The inner of the cylindraceous shell is separated into two levels that an upper and a lower decompression anechoic chamber. The air inlet pipe is welded on the top of the cylindraceous shell. A cylindraceous filter cylinder and a cylinder filter casing on the periphery of a filter cylinder are welded on the inner side of the top of the cylindraceous shell. The air inlet pipe is communicated with the filter cylinder, and the bottom of the cylindraceous shell is welded with a tail pressure reducer. The device has simple structure, low cost, and can decrease the tail gas pressure and noise effectively, as well as has wide practicality and is suitable for mass production.
Description
The utility model relates to a kind of automobile exhaust and the device of eliminating the noise and combining, and is applicable to that various lorry uses.
Contain more objectionable constituent in the vehicle exhaust, air pressure is higher and to produce noise bigger when exhaust emissions, and environment and human health are worked the mischief.For addressing this problem, people adopted many methods.For example, the CN-2125707U patent that on December 23rd, 1992 was announced, it discloses a kind of vehicle exhaust ultimate filter, this device adopts porous connection pipe and filtering net combination, objectionable constituent to tail gas are filtered, but this device filter screen needs distribution in proportion, use chemical reagent to filter simultaneously, cost is higher, and can not be to the decompression of discharging tail gas, noise reduction.
The purpose of this utility model is to provide a kind of decompression noise silencer that filters tail gas when reducing tail gas air pressure and noise.
The purpose of this utility model is achieved in that it comprises cylindrical housing, air inlet pipe, filter plate, cylindrical housing inside is divided into by filter plate, following two-stage decompression anechoic chamber, air inlet pipe are welded on above the cylindrical housing top, and the peripheral filter bowl of filter cylinder and filter cylinder is welded on the cylindrical housing inside top, air inlet pipe communicates with filter cylinder, cylindrical housing bottom welding afterbody pressure reducer.
The filter cylinder of above-mentioned decompression noise silencer and filter bowl are cylindrical, and stack shell and bottom rectangular distribution aperture decompose through double medium filtration, and the pressure and the noise of air-flow effectively reduce, and the dust in the tail gas obtains filtering simultaneously.
The afterbody pressure reducer of above-mentioned decompression noise silencer is a cylindrical filtration cartridges, and the densely distributed aperture in stack shell and bottom disperses the tail gas after filtering layer by layer when discharging, discharge pressure is reduced to minimum.
Advantage of the present utility model is simple in structure, with low cost, and the noise when effectively reducing tail gas air pressure and discharging has extensive practicality, is suitable for producing in enormous quantities.
Fig. 1 is a constructional drawing of the present utility model
Fig. 2 is the A-A cutaway view of Fig. 1
As shown in the figure, cylindrical housing of the present utility model 1 inside is divided into by filter plate 3, following two-stage decompression anechoic chamber, dust and impurity in filter plate 3 filtering gas.Air inlet pipe 2 is welded on above the cylindrical housing top, the peripheral cylindrical filter bowl 5 of cylindrical filtration cartridges 4 and filter cylinder is welded on the cylindrical housing inside top, air inlet pipe 2 communicates with cylindrical filtration cartridges 4, filter cylinder 4 and filter bowl 5 stack shells and bottom rectangular distribution aperture, decompose through double-deck, reduce the noise and the pressure of air-flow, simultaneously the impurity in the filtering gas.Second depressurized noise elimination indoor set is the same, and after eliminating the noise by two-stage decompression, the pressure and the noise of air-flow effectively reduce, and the impurity in the gas obtains filtering simultaneously.Afterbody pressure reducer 6 is welded on the cylindrical housing bottom, and the stack shell of pressure reducer and bottom are provided with intensive aperture, and the tail gas behind the filtration noise reduction is disperseed to discharge, and the differential pressure that will discharge air-flow is to minimum.Above-mentioned decompression noise silencer can weld or be used clip and be fastenedly connected in the vehicle exhaust emissions tube terminal.
This device is installed in outside the former automotive muffler, be connected with freeing pipe, when auto emission tail gas, tail gas is entered in the cylindrical filtration cartridges 4 by air inlet pipe 2, during through filter cylinder stack shell and bottom, because the reason of resistance, pressure and noise in the air-flow are decomposed, impurity in the air-flow is filtered simultaneously, again by peripheral cylindrical filter bowl 5, the pressure and the noise of air-flow are decomposed once more, have at this moment reduced manyly when the pressure of one-level decompression noise elimination indoor air flow and noise enter than just, and contained dust also has been filtered a part in the gas.Gas is by filter plate 3; filter plate enters in the second depressurized anechoic chamber after the impurity in the air-flow is filtered once more; work above repeating is eliminated the noise through two-stage decompression, and pressure and noise in the tail gas are reduced; and the contaminant filter in the tail gas is more thorough; gas enters tail gas pressure reducer 6 at last, and pressure reducer stack shell and bottom many intensive apertures that distribute will be discharged the gas dispersion ejection; pressure when reducing the gas ejection, thereby protection environment and human body health.
