Abstract
The invention provides a novel exhaust ejection postprocessor. A barrel is divided into three chambers by virtue of a front end cover, a rear end cover, a partition plate I and a partition plate II; a carrier assembly is arranged between the partition plate I and the partition plate II; a plurality of small holes are evenly formed in the partition plate I; the novel exhaust injection postprocessor is characterized in that an air inlet pipe penetrates through the front end cover and the first chamber to the second chamber, and is in butted connection with the partition plate II; a plurality of small holes are evenly formed in the pipe wall, located in the second chamber, of the air inlet pipe; an air outlet pipe is arranged on the rear end cover; an ejector pipe is arranged in the air outlet pipe; the other end of the ejector pipe penetrates out from the partition plate II, the second chamber, the partition plate I and the front end cover in sequence. According to the novel exhaust ejection postprocessor, the air inlet pipe is arranged in the second chamber, so that a tail gas returns back to the first chamber from the second chamber; through treatment of the carrier assembly, the circulating path of the tail gas is lengthened; the relatively full and even mixing of the tail gas and atomized urea is facilitated, thus the conversion efficiency of the tail gas is improved; the novel exhaust ejection postprocessor is simple in structure, economic and applicable; the service life of the postprocessor is prolonged.
Description
Technical field
The present invention relates to automobile preprocessor, particularly a kind of new waste gas injection preprocessor.
Background technique
In use for some time, mesh sticks dust to automobile preprocessor carrier, and effective area of contact of coating and waste gas is reduced, and waste gas treatment ability reduces, and the working life of assembly shortens.
Reduce the dust sticked in carrier mesh, increase effective area of contact of mesh surface coating and waste gas, and then lifting carrier uses later stage dust to stick, effective area of contact of coating and waste gas reduces, the problem that waste gas treatment is less able.
The patent No. is: a kind of automobile preprocessor with dust suction of 201120251696.7; comprise front cover, rear end cover, two dividing plates, housing, hush tube assembly, catalyst converter sub-assembly, two temperature transducers, NOx sensor; the forward and backward end bracket enclosed in housing two ends; housing is divided into three chambeies by dividing plate and end cap, and each chamber seals; Hush tube assembly is positioned at the first chamber, and wherein the tail end of hush tube has blanking cover to seal; Catalyst converter sub-assembly two opening end lays respectively at the first, the 3rd chamber, and through the second chamber, wherein catalyst converter sub-assembly is built with the carrier assembly of band coating and liner; Two temperature transducers are contained in the first chamber and the 3rd chamber respectively, and NOx sensor joint is contained in the 3rd chamber; The ash sucking tube of waste gas ejecting device and suction port are on front cover.By installing waste gas ejecting device additional in silencing apparatus inside, maintaining the function of silencing apparatus, cleaning of filter element, ensure that motor air feed is abundant, extend the life-span of filter cleaner and keep the power character of motor.
Its suction tude forms circulation in the first chamber, this circulation directly can cross the second chamber to the 3rd chamber, the effect of such catalyst converter does not just reach requirement, moreover its steam outlet pipe extends in the second chamber, the tail gas also do not handled well can be taken out of in the lump, and overstocking of tail gas can be caused, the harmful substance in preprocessor is increased, affect treatment effect, tail gas indirect also certainly will be caused to discharge.
Summary of the invention
The present invention, in order to improve Processing capacity and the cleaning of off-gas more of the catalyst converter in preprocessor, specially proposes a kind of new waste gas injection preprocessor.
Technological scheme of the present invention is for this reason, a kind of new waste gas injection preprocessor, comprise cylindrical shell, cylindrical shell is divided into three chambers by front and rear cover and dividing plate one, dividing plate two, carrier assembly is provided with between its central diaphragm one and dividing plate two, dividing plate one is evenly provided with multiple aperture, it is characterized in that: suction tude through front cover and the first chamber to the second chamber and and dividing plate two dock, the tube wall of suction tude in the second chamber is evenly provided with multiple aperture; Steam outlet pipe is arranged on rear end cover, is provided with induction tunnel in steam outlet pipe, and the other end of this induction tunnel passes successively from dividing plate two, second chamber, dividing plate one, front cover.
Beneficial effect:
Suction tude in the present invention makes tail gas return the first chamber in the second chamber in the second chamber, again by the process of carrier assembly, extend the circulating path of tail gas, be conducive to tail gas and more fully, uniformly mix with atomize urea, and then improve the transformation efficiency of tail gas.
Air outlet is arranged on rear end cover can discharge the tail gas handled well smoothly, tail gas can not be overstock, and cleaner vent gas treatment, induction tunnel is connected with air-strainer, utilize induction tunnel injection air-flow to make tail gas produce negative pressure, flow through the dust on the negative pressure tail gas removing carrier assembly mesh of carrier assembly.
Structure of the present invention is simple, economic and practical, gives full play to the function of each parts, by the effective utilization of lifting carrier, improves preprocessor and uses later stage waste gas treatment ability, add the working life of preprocessor.
Accompanying drawing explanation
Fig. 1 is plan view of the present invention.
Fig. 2 is the B-B direction view of Fig. 1.
In figure, 1 is cylindrical shell, and 2 are dividing plates one, 3 are carrier assemblies, 4 is dividing plates two, and 5 is front covers, and 6 is rear end covers, and 7 is air inlet ports, and 8 is urea interfaces, and 9 is induction tunnels, 10 air outlet, and 11 is apertures.
Embodiment
The present invention as shown in Figure 1, 2.
A kind of new waste gas injection preprocessor, comprise cylindrical shell 1, cylindrical shell 1 is divided into three chambers by front and rear cover 5 and dividing plate 1, dividing plate 24, carrier assembly 3 is provided with between its central diaphragm 1 republicanism dividing plate 24, dividing plate 1 is evenly provided with multiple aperture 11, air inlet termination 7 through front cover 5 and the first chamber to the second chamber and and dividing plate 24 docking, the tube wall of suction tude 5 in the second chamber is evenly provided with multiple aperture 11; Termination 10 of giving vent to anger is arranged on rear end cover 6, and be provided with induction tunnel 9 in termination 10 of giving vent to anger, the other end of this induction tunnel 9 passes successively from dividing plate 24, second chamber, dividing plate 1, front cover 5.
