Description
Technical field
The present invention relates to a kind of compression type automobile exhaust purifier.
Background technique
Automobile exhaust pollution has become the main source of pollution of atmosphere, and within a period of time from now on, fuel-engined vehicle will be the main product of automotive industry.Recent domestic pays much attention to the research work of purifying vehicle exhaust technology, and high strength of the prior art, high temperature oxidation resisting foamed conducting ceramic material have been applied in purification plant.But because its low temperature active is poor, 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 technological scheme is: comprise shell, also comprises heater, containing the purifying agent of nickel oxide and nickel sesquioxide and glass fibre; Heater adopts XIR Extreme Infrared quartz tube, and be contained in the central authorities of shell, glass fibre is contained in whole shell in space, and purifying agent powder filling is in the space of glass fibre.
In the technological scheme of above-mentioned patent document, heated by heater to purifying agent, make when cold-starting automobile, the molecule participating in reaction arrives activation energy threshold value, and tail gas can be purified.But, because needs arrange heating equipment, single unit system cost is raised.
Summary of the invention
The invention is intended to provide a kind of compression type automobile exhaust purifier, the feature of high speed and high pressure when discharging to utilize tail gas, make tail gas can carry out adiabatic compression in purifying chamber, improve the temperature of tail gas.
Compression type automobile exhaust purifier in this programme, base case is: comprise purifying chamber, the left end of described purifying chamber is communicated with suction tude, the right-hand member of described purifying chamber is provided with end socket, described end socket has exhaust port, the middle part of described end socket is provided with towards the projection of outside, purifying chamber, described projection is arranged with baffle plate, spring is connected with between described projection and baffle plate, ceramic honeycomb plate is provided with in described purifying chamber, described ceramic honeycomb plate is evenly arranged in purifying chamber, and the outer wall of described purifying chamber is provided with thermal-protective coating.
Working principle and beneficial effect: during cold-starting automobile, the exhaust temperature of generation is lower.At this moment, tail gas enters purifying chamber by suction tude, owing to being provided with baffle plate outside exhaust port, and purifying chamber's outer wall is provided with thermal-protective coating, follow-up tail gas carries out adiabatic compression to the tail gas of first discharging, the exhaust temperature of first discharging is raised, reaches the activation temperature of ceramic honeycomb plate, thus improve the effect of filtration.Generation due to tail gas is continuously, 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 ensure that the tail gas of automobile can filter through effective.Finally, when automobile tail gas after filtering reaches purifying chamber's right-hand member, along with the increase of the pressure of tail gas, promote baffle plate, open exhaust port and discharge.
Scheme 2, as the improvement to base case, described purifying chamber is cylindrical shell.Advantage is, is convenient to be placed on automobile domain.
Scheme 3, as the improvement to scheme 2, the sectional area of described purifying chamber is greater than the sectional area of suction tude.Advantage is, the sectional area of purifying 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 projection is provided with the boss of annular.Advantage is, avoids baffle plate to come off.
Scheme 5, as the improvement to base case, described exhaust port is provided with sealing gasket towards the wall outside purifying chamber.Advantage is, avoids baffle plate to the poorly sealed gas leakage caused of exhaust port.
Accompanying drawing explanation
Fig. 1 is the structural representation of compression type automobile exhaust purifier embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: purifying chamber 10, suction tude 20, ceramic honeycomb plate 30, thermal-protective coating 40, exhaust port 50, baffle plate 60, spring 70, projection 80, boss 81.
Embodiment
Compression type automobile exhaust purifier, scheme is: comprise purifying chamber 10, the left end of purifying chamber 10 is communicated with suction tude 20, and the right-hand member of purifying chamber 10 is provided with end socket, end socket has exhaust port 50, the middle part of end socket is provided with towards the projection 80 of outside, purifying chamber 10, projection 80 is arranged with baffle plate 60, between projection 80 and baffle plate 60, is connected with spring 70, in purifying chamber 10, be provided with ceramic honeycomb plate 30, ceramic honeycomb plate 30 is evenly arranged in purifying chamber 10, and the outer wall of purifying chamber 10 is provided with thermal-protective coating 40.
In addition, in the present embodiment, purifying chamber 10 is cylindrical shell.Advantage is, is convenient to be placed on automobile domain.The sectional area of purifying chamber 10 is greater than the sectional area of suction tude 20.Advantage is, the sectional area of purifying 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 projection 80 is provided with the boss 81 of annular.Advantage is, avoids baffle plate 60 to come off.Exhaust port 50 is provided with sealing gasket towards the wall outside purifying chamber 10.Advantage is, avoids the poorly sealed gas leakage caused of baffle plate 60 pairs of exhaust ports 50.
