Description
Technical field
This utility model relates to a kind of self-heating automobile exhaust purifier.
Background technology
Automobile exhaust pollution has become the main source of atmospheric pollution, and within a period of time from now on, fuel-engined vehicle will be the main product of auto industry.Recent domestic pays much attention to the research work of purifying vehicle exhaust technology, and high intensity of the prior art, high temperature oxidation resisting foamed conducting ceramic material have been applied in purifier.But owing to its low temperature active is poor, initiation temperature is higher, and when thus resulting in cold-starting automobile, tail gas clean-up effect is poor.
For the problems referred to above, the patent document of Publication No. CN201461044U discloses a kind of tail gas cleaner for motor-driven vehicle, and its technical scheme is: comprise shell, also comprises heater, containing nickel oxide and the cleanser of nickel sesquioxide and glass fibre；Heater uses far infrared quartz ampoule, is contained in the central authorities of shell, and glass fibre is contained in whole shell in space, and cleanser powder filling is in the space of glass fibre.
In the technical scheme of above-mentioned patent document, being heated cleanser by heater so that when cold-starting automobile, the molecule participating in reaction arrives activation energy threshold value, makes tail gas to be purified.But, owing to needs arrange heater so that single unit system cost raises.
Utility model content
This utility model is intended to provide a kind of self-heating automobile exhaust purifier, the feature of high speed and high pressure during to utilize tail gas to discharge, and makes tail gas can carry out adiabatic compression in clean room, improves the temperature of tail gas.
Self-heating automobile exhaust purifier in this programme, base case is: include clean room, the left end connection air inlet pipe of described clean room, the right-hand member of described clean room is closed, being provided with ceramic honeycomb plate in described clean room, described ceramic honeycomb plate is uniformly arranged in clean room, and the outer wall of described clean room is provided with thermal insulation layer, described clean room has steam vent on the outer wall of right-hand member, is provided with valve at described steam vent.
Operation principle and beneficial effect: during cold-starting automobile, the exhaust temperature of generation is relatively low.At this moment, tail gas is entered clean room by air inlet pipe, owing to being provided with valve, and clean room's outer wall is provided with thermal insulation layer, the follow-up tail gas tail gas to first discharging carries out adiabatic compression so that the exhaust temperature first discharged raises, reach the activation temperature of ceramic honeycomb plate, thus improve the effect of filtration.Owing to the generation of tail gas is continuously, and when automobile normal running, the temperature of tail gas is sufficiently high, so, the tail gas of automobile follow also can reach the activation temperature of ceramic honeycomb plate, thus ensure that the tail gas of automobile can filter through effective.Finally, when automobile tail gas after filtering reaches clean room's right-hand member, along with the increase of the pressure of tail gas, reaching the threshold value of valve setpoint, valve opening discharges.
Scheme 2, as the improvement to base case, described clean room is cylinder.Advantage is, it is simple to be placed on automobile domain.
Scheme 3, as the improvement to scheme 2, the sectional area of described air inlet pipe is less than the sectional area of clean room.Advantage is, the sectional area of clean room 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, described steam vent is arranged on the wall on top, clean room.Advantage is, valve can be made to arrange the wall on top, clean room, it is simple to checks and changes.
Scheme 5, as the improvement to base case, is provided with rupture disk at the end socket of described clean room right-hand member.Advantage is, rupture disk and valve in parallel, it is to avoid valve invalidation.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model self-heating automobile exhaust purifier embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: clean room 10, air inlet pipe 20, ceramic honeycomb plate 30, thermal insulation layer 40, steam vent 50, valve 60.
Embodiment
Self-heating automobile exhaust purifier, scheme is: include clean room 10, the left end connection air inlet pipe 20 of clean room 10, the right-hand member of clean room 10 is closed, being provided with ceramic honeycomb plate 30 in clean room 10, ceramic honeycomb plate 30 is uniformly arranged in clean room 10, and the outer wall of clean room 10 is provided with thermal insulation layer 40, clean room 10 has steam vent 50 on the outer wall of right-hand member, is provided with valve 60 at steam vent 50.
It addition, in the present embodiment, clean room 10 is cylinder.Advantage is, it is simple to be placed on automobile domain.The sectional area of air inlet pipe 20 is less than the sectional area of clean room 10.Advantage is, the sectional area of clean room 10 can make greatly exhaust flow one timing reduce the flow velocity of tail gas, increases the time that oxidation is filtered.Steam vent 50 is arranged on the wall on top, clean room 10.Advantage is, valve 60 can be made to arrange the wall on top, clean room 10, it is simple to checks and changes.It is provided with rupture disk at the end socket of clean room 10 right-hand member.Advantage is, rupture disk is in parallel with valve 60, it is to avoid valve 60 lost efficacy.
During cold-starting automobile, the exhaust temperature of generation is relatively low.At this moment, tail gas is entered clean room 10 by air inlet pipe 20, owing to being provided with valve 60, and clean room 10 outer wall is provided with thermal insulation layer 40, the follow-up tail gas tail gas to first discharging carries out adiabatic compression, 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 continuously, and when automobile normal running, the temperature of tail gas is sufficiently high, so, the tail gas of automobile follow also can reach the activation temperature of ceramic honeycomb plate 30, thus ensure that the tail gas of automobile can filter through effective.Finally, when automobile tail gas after filtering reaches clean room's 10 right-hand member, along with the increase of the pressure of tail gas, reaching the threshold value that valve 60 sets, valve 60 is opened and is discharged.
