Abstract
The utility model relates to a secondary purification silencer for automobile tail gas. The utility model is composed of an outer casing, a heat and sound insulating cushion layer made of aluminum silicate fibers, an inner cylinder, an isolation pattern board, a fine hole sound insulating layer, a catalyst layer, a thick hole sound insulating layer, a first purification chamber, a second purification chamber and an air inlet valve, wherein, an outer wall structure is divided into three layers of the outer casing, the heat and sound insulating cushion layer and the inner cylinder, the casing inner structure is additionally provided with the fine hole sound insulating layer and the thick hole sound insulating layer in the fine hole sound insulating layer and is separated by the isolation pattern board, the isolation pattern board divides the whole silencer chamber into the first purification chamber and the second purification chamber, and a part communicated with outside between the first purification chamber and the second purification chamber is provided with the air inlet valve. The utility model uses a secondary purification structure, harmful gas in automobile tail gas are purified further, and discharged gas can come up to the standards. The sound insulating device with multiple layers effectively control noise.
Description
Technical field:
The utility model relates to a kind of purifying silencing device of vehicle exhaust, belongs to International Classification of Patents F01N3/10 and " has purification function, make to become nontoxic or other exhaust gas treatment device " field.
Background technique:
Automobile pollution every year of China is with about 10% speed increment.Expect 2010 and will reach 5,000 ten thousand.Show that according to the national departments concerned statistics one ton of gasoline of every combustion just produces harmful matter 40-70Kg, its pollution level really is startling.The exhaust emissions level that China's motor vehicle are described thus is in not controlled as yet situation substantially.Existing baffler is total two-layer, is not provided with the function of not saturating honeycomb absorption sound source; There is not fine and closely woven hole puigging; Do not adopt the damping bed course of specialty fibers.Therefore, eliminate and be harmful at noise and all do not reach requirement aspect the vent gas treatment.
Summary of the invention:
The purpose of this utility model is to overcome defective of the prior art, and a kind of harmful gas of eliminating vehicle exhaust that has is provided, and can better solve the vehicle exhaust double purification baffler of automobile noise.
The technical solution of the utility model is as follows.
A kind of vehicle exhaust double purification baffler, heat-insulating sound-insulating bed course (2), the inner core of making by shell (1), aluminum silicate fiber (3), isolate card (4,8,11), fine and closely woven hole puigging (5,9), catalyst layer (6,12), the gross porosity puigging (7,10) made by the stainless steel acoustic board, for the first time cleaning position (13), cleaning position (15), air inlet valve (14) are formed for the second time, its outer wall construction is divided into three layers, the inner core (3) that is followed successively by shell (1), heat-insulating sound-insulating bed course (2) from outside to inside and adopts not saturating honeycomb sound-absorbing steel plate to make; Shell inner structure: in inner core (3), be provided with the fine and closely woven hole puigging (5,9) that steel plate is made, fine and closely woven hole puigging (5) is positioned at the periphery of gross porosity puigging (7), gross porosity puigging (7) constitutes the outer wall of cleaning position (13) for the first time, separates with gas inlet by isolating card (4); Fine and closely woven hole puigging (9) is positioned at the periphery of gross porosity puigging (10), and gross porosity puigging (10) constitutes the outer wall of cleaning position (15) for the second time, and separates with previous stage purification import by isolating card (11); Whole baffler storehouse is by isolating card (8) separated into two parts: cleaning position (13) and cleaning position (15) for the first time for the second time, the part in the intermediate connection external world, two storehouses is provided with air inlet valve (14).
Inner core (3) adopts not saturating honeycomb sound-absorbing steel plate to make, and at last lingering sound is adsorbed in the honeycomb.Gross porosity puigging (7,10) adopts the stainless steel acoustic board to make.Fine and closely woven hole puigging (5,9) adopts steel plate.
Because the utility model has adopted the double purification structure, thereby the harmful gas in the vehicle exhaust further can be purified, and makes the gas that gives off up to standard.Adopt multi-level noise insulation equipment, make noise obtain good control.
Description of drawings:
Fig. 1 is an overall structure schematic representation of the present utility model.
Among the figure: 1, shell, 2, the heat-insulating sound-insulating bed course, 3, inner core, 4, isolate card, 5, fine and closely woven hole puigging, 6, catalyst layer, 7, gross porosity puigging, 8, isolate card, 9, fine and closely woven hole puigging 10, gross porosity puigging, 11, isolate card, 12, catalyst layer, 13, cleaning position for the first time, 14, the air inlet valve, 15, cleaning position for the second time.
Embodiment:
Adopt the anti-rotten perforated plate of metal stainless steel heat resistanceheat resistant to make in first cleaning position, and adorned firm cellular integral body, be coated with the platinum environmental protection, titanium dioxide semiconductor light anode catalyst.When vehicle exhaust entered first cleaning position, chemical reaction under the effect of catalyzer, took place in contained dusty gass such as CO/HC/NO2 in the tail gas.Vehicle exhaust is converted into innocuous gas and water by the reaction of catalyzer.Reaction velocity is fast, and the space is little.Adopt the heat resistanceheat resistant of metal stainless steel to resist rotten perforated plate in second cleaning position, and adorned the molecular sieve catalyst that nontoxic pollution-free can be regenerated, had special transformation function.Through double purification, reach the effect of thorough cleaning of off-gas.
