Description
Technical field
The utility model relates to a kind of compression formula automobile exhaust purifier.
Background technology
Automobile exhaust pollution has become the main source of topsoil, and within for some time from now on, fuel-engined vehicle will be the main product of automotive industry. Paying much attention to the research work of purifying vehicle exhaust technology in recent years both at home and abroad, high strength of the prior art, high temperature oxidation resisting foamed conducting ceramic material have been applied in refining plant. But owing to its low temperature active is poor, combustion initiation temperature is higher, when thus causing cold-starting automobile, tail gas clean-up effect is poor.
For the problems referred to above, publication number is that the patent document of CN201461044U discloses a kind of tail gas cleaner for motor-driven vehicle, and its technical scheme is: comprise shell, also comprises well heater, containing the scavenging agent of nickel oxide and nickel sesquioxide and glass fibre; Well heater adopts far infrared rays silica tube, is contained in the central authorities of shell, and glass fibre is contained in whole shell in space, and scavenging agent powder filling is in the space of glass fibre.
In the technical scheme of above-mentioned patent document, being heated by scavenging agent by well heater so that when cold-starting automobile, the molecule participating in reaction arrives activation energy threshold value, and tail gas can be purified. But, owing to needs arrange heating unit so that overall installation cost raises.
Practical novel content
The utility model is intended to provide a kind of compression formula automobile exhaust purifier, and the feature of high speed and high pressure during to utilize tail gas to discharge, makes tail gas can carry out adiabatic compression in decontamination chamber, it is to increase the temperature of tail gas.
Compression formula automobile exhaust purifier in this scheme, base case is: comprise decontamination chamber, the left end of described decontamination chamber is connected inlet pipe, the right-hand member of described decontamination chamber is provided with end socket, described end socket has venting hole, the middle part of described end socket is provided with the convex post towards outside, decontamination chamber, described convex post is arranged with baffle plate, it is connected with spring between described convex post and baffle plate, it is provided with ceramic honeycomb plate in described decontamination chamber, described ceramic honeycomb plate is evenly arranged in decontamination chamber, and the outer wall of described decontamination chamber is provided with thermofin.
Principle of work and useful effect: during cold-starting automobile, the exhaust temperature of generation is lower. At this moment, tail gas enters decontamination chamber by inlet pipe, owing to being provided with baffle plate outside venting hole, and decontamination chamber's outer wall is provided with thermofin, the tail gas first discharged is carried out adiabatic compression by follow-up tail gas, the exhaust temperature first discharged is raised, reaches the activation temperature of ceramic honeycomb plate, thus improve the effect of filtration. Owing to the generation of tail gas is successive, and when automobile normal running, the temperature of tail gas is enough high, so, the tail gas of automobile follow also can reach the activation temperature of ceramic honeycomb plate, thus the tail gas that ensure that automobile can filter through effective. Finally, when automobile tail gas after filtering reaches decontamination chamber's right-hand member, along with the increase of the pressure of tail gas, promote baffle plate, open venting hole and discharge.
Scheme 2, as the improvement to base case, described decontamination chamber is cylinder. Advantage is, is convenient to be placed on automobile domain.
Scheme 3, as the improvement to scheme 2, the sectional area of described decontamination chamber is greater than the sectional area of inlet pipe. Advantage is, the sectional area of decontamination chamber can make greatly exhaust flow one timing reduce the flow velocity of tail gas, increases the time that oxidation is filtered.
Scheme 4, as the improvement to base case, one end of described convex post is provided with the boss of annular. Advantage is, avoids baffle plate to come off.
Scheme 5, as the improvement to base case, described venting hole is provided with gasket towards the wall face outside decontamination chamber. Advantage is, avoids baffle plate to the poorly sealed gas leakage caused of venting hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model compression formula automobile exhaust purifier embodiment.
Embodiment
Below by embodiment, the utility model is described in further detail:
Reference numeral in Figure of description comprises: decontamination chamber 10, inlet pipe 20, ceramic honeycomb plate 30, thermofin 40, venting hole 50, baffle plate 60, spring 70, convex post 80, boss 81.
Embodiment
Compression formula automobile exhaust purifier, scheme is: comprise decontamination chamber 10, the left end of decontamination chamber 10 is connected inlet pipe 20, and the right-hand member of decontamination chamber 10 is provided with end socket, and end socket has venting hole 50, the middle part of end socket is provided with the convex post 80 towards outside, decontamination chamber 10, convex post 80 is arranged with baffle plate 60, is connected with spring 70 between convex post 80 and baffle plate 60, in decontamination chamber 10, is provided with ceramic honeycomb plate 30, ceramic honeycomb plate 30 is evenly arranged in decontamination chamber 10, and the outer wall of decontamination chamber 10 is provided with thermofin 40.
In addition, in the present embodiment, decontamination chamber 10 is cylinder. Advantage is, is convenient to be placed on automobile domain. The sectional area of decontamination chamber 10 is greater than the sectional area of inlet pipe 20. Advantage is, the sectional area of decontamination chamber 10 can make greatly exhaust flow one timing reduce the flow velocity of tail gas, increases the time that oxidation is filtered. One end of convex post 80 is provided with the boss 81 of annular. Advantage is, avoids baffle plate 60 to come off. Venting hole 50 is provided with gasket towards the wall face outside decontamination chamber 10. Advantage is, avoids baffle plate 60 to the poorly sealed gas leakage caused of venting hole 50.
During cold-starting automobile, the exhaust temperature of generation is lower. At this moment, tail gas enters decontamination chamber 10 by inlet pipe 20, owing to being provided with baffle plate 60 outside venting hole 50, and decontamination chamber 10 outer wall is provided with thermofin 40, the tail gas first discharged is carried out adiabatic compression by follow-up tail gas, the exhaust temperature first discharged is raised, reaches the activation temperature of ceramic honeycomb plate 30, thus improve the effect of filtration. Owing to the generation of tail gas is successive, and when automobile normal running, the temperature of tail gas is enough high, so, the tail gas of automobile follow also can reach the activation temperature of ceramic honeycomb plate 30, thus the tail gas that ensure that automobile can filter through effective.
