Abstract
The invention belongs to Motor Vehicle noise elimination cleaning equipment field.Mainly solve organic harmful components transformed technology problem in Motor Vehicle noise and the tail gas.The present invention has suction tude by a front, and the back has the silencing and purifying device of automotive vehicle that the cylindrical metal shell of outlet pipe is made, and the noise elimination purifying agent is equipped with in the inside.This device is installed on the outlet pipe of Motor Vehicle, can makes Motor Vehicle under the constant situation of power, oil consumption and exhaust resistance, reduce by 9 decibels of noises, the conversion ratio of harmful components in the former motor-vehicle tail-gas is respectively: total hydrocarbon 50%, carbon monoxide 17.6%, nitrogen oxide 48.5%, formaldehyde 67%, methyl alcohol have significantly reduced environmental pollution more than 90%.
Description
The invention belongs to Motor Vehicle noise elimination cleaning equipment field.
Because Motor Vehicle noise and exhaust emissions had caused serious harm to cities and towns already along with vehicle guaranteeding organic quantity grows with each passing day, its pollution level accounts for 1/3rd of entire environment pollution, has become the problem of domestic and international close attention.
At present, being used for Motor Vehicle both at home and abroad has independent silencing apparatus, and independent purifier is also arranged, but motor vehicle muffler purifier is not arranged as yet.As external purifier (patent No. is J4804298863) is to carry out catalytic combustion and cleaning of off-gas with platinum palladium precious metal.Its shortcoming is to cost an arm and a leg, lead poisoning easily, and can not eliminate the noise.Active carbon also of no use carries out the silencing and purifying device of automotive vehicle of absorption noise and waste gas.
Purpose of the present invention is exactly that with active carbon, hopcalite agent is a Main Ingredients and Appearance in order to overcome above-mentioned shortcoming, utilizes organic harmful gas and other oxious components in active carbon porous and microcellular structure absorption Motor Vehicle noise and the tail gas.Utilize the active comprehensive regulation noise of active carbon and other aids and the oxious component in the tail gas and study successful.
The present invention studies successful silencing and purifying device of automotive vehicle (shown in the accompanying drawing), by a cylinder blanket made from the 1-1.5mm sheet metal (shown among the figure 1), the inside is a hollow, the radiation hole of even 16 7mm that distribute on the circumferential surface of cylinder blanket, a suction tude of welding (shown among the figure 2) connection motor-vehicle tail-gas exhaust pipe is used on the disc of the anterior top of cylinder blanket.Be used for discharging eliminating the noise at outlet pipe of the rear portion of cylinder blanket welding (see among the figure shown in 3) and purify back gas and use.Cylinder blanket the inside hollow space first three/position makes a cylindrical dictyosome of concavity with wire armature support metal net, it is long 1/3rd the hollow space for cylindrical dictyosome of garden column diameter 1/2nd that a diameter is arranged in this columniform centre, the noise elimination purifying agent for preparing is housed, (shown among the figure 4) in the cylindrical metal dictyosome.Having one at cylinder blanket the inside hollow space, to account for cylinder blanket the inside hollow space sixth long, the spacer ring made from sheet metal (shown among the figure 5).Contacting with spacer ring, a length is arranged is the cylinder blanket sixth to part, and the cylinder dictyosome (shown among the figure 6) with wire armature and wire netting are made is equipped with the noise elimination purifying agent for preparing in the wire netting.Place a cirque body (shown among the figure 7) of making by wire armature support metal net in last 1/3rd of the cylinder blanket hollow space long positions, toric core is that the diameter of hollow is 1/2nd of a cirque body diameter, and the noise elimination purifying agent for preparing is housed in the wire netting.Wire netting recited above is a 10-20 purpose mesh.The noise elimination purifying agent of dress in the wire netting.Be mixed with by active carbon and hopcalite agent.The weight percentage of active carbon and hopcalite is respectively: active carbon 85-95%, hopcalite agent are 15-5%, and its best proportioning is that active carbon accounts for 91%, and hopcalite agent accounts for 9%.
The noise elimination purifying agent is packed into by above-mentioned best proportioning in the silencing and purifying device of automotive vehicle, be used for Motor Vehicle, its power, exhaust resistance, oil consumption is constant, and noise can reduce by 9 decibels, can make in the tail gas total hydrocarbon conversion rate is 50%, the carbon monoxide conversion ratio is 17.6%, and transformation efficiency of the oxides of nitrogen is 48.5%, and the formaldehyde conversion ratio is 67%, methanol conversion is more than 90%, to have significantly reduced environmental pollution.
