Abstract
The utility model relates to an automobile tail gas purification silencer. The automobile tail gas purification silencer comprises a gas inlet pipe, an exhaust pipe and a purification silencer, wherein, the gas inlet pipe is connected with a heat radiator formed by the series connection of a heat radiating sheet type pipe, a heat radiator assembly and a pipe separating type heat radiating pipe, a heat radiating sheet is arranged on an outer casing, a filter core with a sound insulating plate is arranged in the inner cavity of the purification silencer with a tapered structure on the top end, and filter paper is arranged on the filter core. Gas exhausted by an engine enters the heat radiating sheet type pipe, the heat radiator assembly and the pipe separating type heat radiating pipe to carry out heat radiation and temperature reduction step by step through a gas pipe. When the gas reach the safe temperature required by the filter paper in the purification silencer, the gas which enters the purification silencer again is filtered through the filter paper in the purification silencer and is exhausted from the exhaust pipe after silencing. The utility model has the advantage of simple structure, the temperature of automobile tail gas exhausted by the engine can be lowered, carbonization granules in tail gas can be filtered totally, and meanwhile, the effect of sound silencing can be reached. Thereby, air can be effectively purified, and environment pollution can be treated. The utility model can be widely used for gas automobiles and diesel oil automobiles.
Description
Technical field
The utility model relates to a kind of purifying vehicle exhaust silencer.
Background technique
The improvement of automobile exhaust pollution environment is the important content that city atmospheric environment is administered.At present, solve the purifying silencing device of automobile exhaust pollution problem, the split structural formula is arranged, be two separate devices promptly to the aseptic purification plant of vehicle exhaust with to the silencer that vehicle exhaust plays the noise elimination effect, though this device has solved the purifying silencing problem of vehicle exhaust, but it makes automobile noise reduction and purification function be separated from each other, and does not possess integrity.Existing can making in the device that purifying vehicle exhaust and noise elimination function be integrated; have plenty of the filter screen of in existing silencer, packing into and reach the purifying silencing purpose; have plenty of and in silencer, adopt water as medium to reach purification purpose water adsorption method; have plenty of the solid absorbent that adopts carbon granule or carbon granule and other material to form and make the solid absorbent adsorption method of medium in silencer, the employing catalyzer method that also has reaches the purification and the noise reduction purpose of vehicle exhaust.These administer the method for vehicle exhaust, and its shortcoming is that absorbing capacity is limited, can not effectively reduce the motor vehicle exhaust emission temperature, and the carbonized particle in the tail gas can not be filtered fully.
Summary of the invention
The utility model solves existing vehicle exhaust in by noise reduction, though can not be cleaned simultaneously and can reach the purification purpose simultaneously, but the technical problem that the granular charring thing can not be filtered fully, provide a kind of and can reduce the motor vehicle exhaust emission temperature, carbonized particle in the tail gas all is filtered, can also reaches the purifying vehicle exhaust silencer of erasure effect simultaneously.
The purpose of this utility model is achieved in that because purification silencer of the present utility model adopts filter paper to filter, higher by the gas that motor is discharged owing to temperature, the burning-point that is much higher than filter paper, the purification silencer that can not directly enter in this device filters, and just can filter after therefore need lowering the temperature.Therefore at first must be to the high-temperature tail gas that motor the is discharged processing of lowering the temperature.The utility model adopts the structure of cooling step by step, can make exhaust temperature drop to the safety requirement of filter paper, thereby realize the purification filtering purpose.
A kind of purifying vehicle exhaust silencer, include suction tude, outlet pipe, purification silencer, it is characterized in that being connected with on the suction tude sink that forms by heat radiation type heat dissipating pipe, heat radiator assembly and tube-separating type heat dissipating pipe serial connection, the inner chamber that has radiating fin, top on the shell and be the purification silencer of cone structure is equipped with the filter core of band insulation board, and filter paper is housed on the filter core.
The gas that motor is discharged enters heat radiation type heat dissipating pipe, heat radiator assembly and tube-separating type heat dissipating pipe through suction tude and carries out radiating and cooling step by step, after reaching the safety temperature of filter paper requirement in the purification silencer, enter purification silencer again, filter, discharge from outlet pipe after the noise reduction by the filter paper in the purification silencer.
Heat radiator assembly of the present utility model adopts the tube-separating type structure, in order to increase heat diffusion area.
Cone structure is adopted on the filter core top of purification silencer of the present utility model, can reduce the resistance of air.
The beneficial effects of the utility model are: simple in structure, and low cost of manufacture, the vehicle exhaust temperature that motor is discharged reduces, and the carbonized particle in the tail gas all is filtered, and can reach the noise elimination effect simultaneously, thereby effectively purify air, and curbs environmental pollution.Can be widely used in gasoline locomotive and diesel locomotive.

Embodiment
Annular fin formula heat dissipating pipe 3 of the present utility model, upright heat radiation type heat dissipating pipe 4, heat radiator assembly 5, tube-separating type heat dissipating pipe 7 are serially connected by bridge piece 2 and connecting plate 6 respectively, constitute sink of the present utility model.It is local preferably that wherein heat radiator assembly 5 is contained in ventilation, and fan 15 is equipped with at heat radiator assembly 5 rear portions, when Motor Vehicle upward slope or overburdening low speed driving, fan 15 opened, to increase the radiating effect of heat radiator assembly 5.The length of tube-separating type heat dissipating pipe can determine that long more radiating effect is good more according to the space situation.Suction tude 1 links to each other with sink by bridge piece 2, and outlet pipe 14 links to each other with purification silencer 12, and connecting tube 8 passes through connecting plate 6, pipe collar 9 is connected sink with purification silencer 12 and fix.Filter paper on the filter core 13 need regularly be changed.
The gas of discharging when motor is after suction tude 1 enters, lower the temperature step by step through the annular fin formula heat dissipating pipe 3 of sink, upright heat radiation type heat dissipating pipe 4, heat radiator assembly 5, tube-separating type heat dissipating pipe 7, and after reaching the safety temperature of filter paper requirement in the purification silencer 12, enter purification silencer 12 inner chambers through connecting tube 8, vent 11 from insulation board 10 passes through, and the inlet hole after filter core 13 filters from the outlet pipe 14 enters outlet pipe 14 and discharges.Because vent 11 disperses air-flow, filter paper had both had the filtration suction-operated, can reach the noise elimination soundproof effect again, and the exhaust temperature of final discharge is reduced greatly, and the charing particle all is filtered, thereby reaches the purifying silencing purpose.
