Description

Motor Vehicle noise reduction purifying exhaust gas device

Technical field

The present invention relates to a kind of automobile-use venting gas appliance, be specifically related to a kind of Motor Vehicle noise reduction purifying exhaust gas device.

Background technique

In recent years, along with steady development of economy, people's living standard significantly improves, various motor vehicle also progressively enter the common people other, at present, China's vehicle possess amount has surpassed 1.6 hundred million, follow extremely then be atmospheric pollution and the noise pollution that motor vehicle produce, caused very big threat for people's living environment.Existing automobile exhausting device mostly passes through outlet pipe, expansion chamber and cotton material noise reduction, catalyzer emission abatement waste gas.Venting gas appliance pipeline structure complexity, catalyzer are easily aging, the manufacture cost height, thus also strengthened the Motor Vehicle cost, also can bring certain influence to the sales volume of motor vehicle.

Summary of the invention

The purpose of this utility model is to overcome existing in prior technology venting gas appliance complex structure, and the shortcoming and defect that cost of production is high provides a kind of Motor Vehicle noise reduction purifying exhaust gas device.Both can satisfy the requirement of noise reduction and cleaning of off-gas, reduce the device fabrication cost again largely.

Above-mentioned purpose of the present utility model is achieved in that

The technical solution adopted in the utility model comprises casing, suction tude and outlet pipe.It is characterized in that: casing is a seal container, and outlet pipe directly is communicated with the top of casing; Suction tude vertically is placed in the casing, and the end sealing of suction tude also is fixed on lower box, and the other end passes from casing top and is connected with box sealing, is communicated with the gas-distributing pipe that is distributed with more than 2 from bottom to top near closed end on the body; Each gas-distributing pipe on the suction tude all is connected with hush pipe, its afterbody sealing, and the body perisporium is evenly distributed with the plurality of rows pore, and each hush pipe level respectively closely coils curl, and mutual hierarchal arrangement is in casing.Casing top is provided with the acoustical panel more than 1, is evenly distributed with some apertures on the acoustical panel; Be injected with water in the casing, each hush pipe of water flooding and a little less than acoustical panel.

The beneficial effects of the utility model are: hush pipe can be eliminated exhaust noise; Water can adsorb, dissolve the harmful components in the combustion gas; Acoustical panel both can further have been eliminated time noise, can play again to suppress hush pipe and enter the surge that gas caused in the water.Simple and practical, low cost of manufacture, applied widely, effect is good, not only energy-conservation but also environmental protection.

Embodiment

As depicted in figs. 1 and 2, make diameter 200mm with sheet metal, high 300mm seal container is as casing 1, and cut-off is 30mm directly, and the metal tube of long 100mm is made outlet pipe 3, outlet pipe 3 is welded on the shell on casing 1 top, and directly is communicated with box house; Cut-off footpath 50mm, the metal tube of long 400mm is done suction tude 2, with the sealing of suction tude one end, and in closed end 1/2nd sections to the air inlet pipe range, 4 the external diameter 10mm of installation that evenly distribute from bottom to top, the gas-distributing pipe 4 of long 20mm, gas-distributing pipe and suction tude 2 internal communication; Suction tude 2 vertically is placed in the casing 1, and the suction tude closed end is weldingly fixed on lower box, the other end pass from casing 1 top and with the cabinet shell seal welding; Get internal diameter 10mm, long 1.5 meters plastic cement pipe is made hush pipe 5, even distribution of noise reduction body perisporium the exhaust port 6 of some diameter 1mm～3mm is set, 4 hush pipes 5 are installed in respectively on each gas-distributing pipe 4, the sealing of hush pipe afterbody, each hush pipe level respectively closely coils curl, and mutual layering fixed arrangement is in casing 1.Get the corrugated sheet that 2 diameters are slightly less than 200mm and make acoustical panel, the aperture 8 of some diameter 2mm is set on the plate face, the density that is provided with of aperture evenly distributes according to 1～6 every square centimeter.2 acoustical panels are installed in casing top, are injected with water in the casing, water line 9 is higher than each hush pipe 5 and a little less than two acoustical panels 7.

Working principle of the present utility model is as follows: motor car engine institute waste discharge gas enters from suction tude 2, from 4 fens inflow hush pipes 5 of gas-distributing pipe, waste gas is distributed to each exhaust port 6 and enters in the water in the casing 1, by the aperture 8 on the acoustical panel 7, enters atmosphere from outlet pipe 3 through the water purified gas.
