The present invention relates to a kind of purifying silencing combination unit.
Background technique
The outlet pipe of Motor Vehicle can be provided with usually baffler to carry out noise reduction; the kind of baffler has resistant noise-reducing device, resistive muffler, active baffler usually; simultaneously because the pollution of motor-vehicle tail-gas all the more seriously makes the requirement of the purification to tail gas more and more stronger this year for environment; the current purification to tail gas and noise reduction are normally separately carried out; usage space is comparatively large, and assembly process is many.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of purifying silencing combination unit, this purifying silencing combination unit reaches the combined effect of noise reduction and purification by the purifying tablets of installation ingenious in rotating wheel type resistant noise-reducing structure, rotating wheel type resistant noise-reducing device itself has excellent tandem type erasure effect, and the mounting structure convenient disassembly of purifying tablets, be convenient to change, make the good stability of the Long-Time Service purifying property of whole device, long service life.
The present invention's adopted technological scheme that solves the problem is:
Comprise baffler cylindrical shell, suction tude, outlet pipe, also comprise central cylinder and at least 4 pieces of interlayer dividing plates, Figure 2 shows that the situation of 8 pieces of interlayer dividing plates, but be easy to expect that actual employing at least 4 pieces of dividing plates are divided into 4 chambers and can realize simple structure, described interlayer dividing plate is separated out a layer slot by two pieces of single layer separator and forms, described layer slot is purifying tablets installation cavity, filter screen purifying tablets is provided with in described purifying tablets installation cavity, interlayer dividing plate connects central cylinder outer wall and baffler cylinder inboard wall, installation direction is that septum plane is parallel with baffler cylindrical shell axial direction, space between noise reduction cylinder inboard wall and central cylinder outer wall is separated into suction tude chamber by interlayer dividing plate, outlet pipe chamber, first chamber group, second chamber group, described suction tude chamber is in the below of baffler, described outlet pipe chamber is in above baffler, described first chamber group is in the right side of suction tude chamber, outlet pipe chamber, comprises at least 1 chamber, described second chamber group is in the left side of suction tude chamber, outlet pipe chamber, comprises at least 1 chamber, described first chamber group is consistent with the chamber quantity of the second chamber group and the quantity of interlayer dividing plate, this determines by structure itself is implicit, the relative position relation of above-mentioned chamber and baffler obtains by the B-B place sectional drawing of baffler in such as Fig. 1, actual first chamber group and the title of the second chamber group can be exchanged technological scheme and still to be set up and essential scope is identical, here be only sake of clarity and distinguish left and right, baffler cylindrical shell integral sealing
Described suction tude stretches into suction tude chamber by the inlet end of baffler cylindrical shell, described outlet pipe stretches into outlet pipe chamber by the exhaust end of baffler cylindrical shell, described suction tude, the outlet pipe portion stretched in baffler has multiple staggered suction tude exhaust port, outlet pipe inlet hole
Each single layer separator of described interlayer dividing plate all has the chamber through hole be interspersed, baffler cylindrical shell inlet end, exhaust end are respectively arranged with the suction tude end cap discrete with baffler cylindrical shell, outlet pipe end cap, suction tude end cap, outlet pipe end cap arrange end cap flange plate, baffler cylindrical shell and end cap joint seal of flanges cylindrical shell.
This purifying silencing combination unit working principle is specially, 1, wherein rotating wheel type resistant noise-reducing structure is by suction tude chamber, outlet pipe chamber, first chamber group, the setting that second chamber group is along the circumferential direction arranged changes the noise reduction chamber arrangement of the axial cascade of baffler, air-flow is by along the circumferential direction circulating, circulating direction is: suction tude-> suction tude chamber-> first chamber group or the second chamber group-> outlet pipe chamber-> outlet pipe, make to make use of interlayer dividing plate that chamber group distributes the vertically resonance side as chamber, improve the area ratio of resonance side and air-flow path entrance, improve chamber resistance noise reduction efficacy, in the design in resistant noise-reducing chamber, the area ratio of resonance side and air-flow path entrance is improve the important indicator of sound absorption cavity efficiency, here the increase of area ratio can play beneficial effect to the erasure effect of silencing cavity, simultaneous wheels turns cavity configuration airflow and constitutes two air-flow path along two paths of the first chamber group or the second chamber group, thus two-way noise reduction, and the filtering net plate cleverly by arranging in interlayer dividing plate on air flow path purifies tail gas, improve with this utilization ratio that wheel turns muffler cavity, in addition, when the baffler cylindrical shell of equal length, because wheel turns cascade, the length that suction port stretches into cavity is longer, air-flow buffer better effects if, the situation that overall erasure effect cylindrical shell volume is identical contrasts the baffler of axial cascade, and its noise reduction can improve 2-3dB, 2, take turns the airflow connection turning chamber to be realized by the chamber through hole on interlayer dividing plate, staggered suction tude exhaust port and outlet pipe inlet hole, concrete purification process realizes in purifying tablets chamber, in using process, the purification efficiency of filter screen purifying tablets declines needs cleaning or changes to be undertaken by the dismounting of flange plate, suitable convenience.
This purifying silencing combination unit adopts the purifying tablets of ingenious installation in rotating wheel type resistant noise-reducing structure to reach the combined effect of noise reduction and purification, rotating wheel type resistant noise-reducing device itself has excellent tandem type erasure effect, and the mounting structure convenient disassembly of purifying tablets, be convenient to change, make the good stability of the Long-Time Service purifying property of whole device, long service life.
Further, between described end cap flange and the Flange joint of baffler cylindrical shell, rubber flange gasket circle is set.Rubber flange gasket circle is the preferred mode ensureing sealing.
Further, the quantity of described interlayer dividing plate is 8 pieces, and the chamber quantity that the first corresponding chamber group, the second chamber group comprise is 3.That takes turns turn eight chambers is designed to preferred chamber quantity, and guarantee chamber length is balanced with cascading effect, and noise reduction is also in close to best noise reduction.
