The exhaust gas post-treatment device of state IV, state V mainly contains four classes: penetrating type granule capturing preprocessor (POC), the diesel oil oxidation catalysis preprocessor (DOC) of Selective catalytic reduction preprocessor (SCR), band catalyst coat, diesel particulate filtration post-processor (DPF).Meet the structural design of post-processor assembly of Abgasgesetz of state IV, state V, the carrier that need adapt to above four kinds of reprocessing routes is arranged, and consider arrangement space and noise reduction requirement, manufacturing process difficulty and assembly cost to be reduced simultaneously, increase the competitiveness of product in market.
Comparative maturity applied by external preprocessor, and domestic preprocessor industry is at the early-stage.The form of preprocessor is had nothing in common with each other, for adapting to different engine performance and arrangement needs, profile has box, drum type, have and be arranged in frame outside, also be arranged in vehicle frame inboard, its arrangement principle is the arrangement requirement that will meet metallic hose and urea injection system, ensures that metallic hose has enough straightways for vibration isolation, have sufficiently long urea mixing length after ensureing urea nozzle, this will meet as above requirement by the position and suction port regulating preprocessor.
Summary of the invention
The purpose of this utility model is to provide a kind of square post-processor assembly of upper air, and traditional silencing apparatus and preprocessor integrate by it, provides one can realize reducing discharge and engine noise simultaneously, and possesses the device of enough market competitiveness.
The technical solution of the utility model is achieved in that a kind of square post-processor assembly of upper air, it is characterized in that: rear end cover and outer casing back are tightly connected, front cover and case nose are tightly connected, rear bulkhead is arranged in fragment position behind case body inside, front baffle arrangement is at shell enclosure interior front-end position, post-processing unit is arranged in top between rear bulkhead and front dividing plate, noise reduction unit is arranged between rear bulkhead and front dividing plate, the lower position of post-processing unit, post-processing unit rear end is spacing by rear bulkhead, front end is spacing by front dividing plate, it is inner that suction tude inserts case body from cover top portion, suction tude particular location is between front dividing plate and front cover, it is mixed cell between front dividing plate and front cover, pore in suction tude is positioned at shell bottom partially, flange is fixedly connected with suction tude top, outlet pipe is successively through front cover, front dividing plate and rear bulkhead, outlet pipe is specifically positioned at case body inner bottom part, the noise reduction unit position of filter pore between front dividing plate and rear bulkhead of outlet pipe, tailpipe is fixedly connected with outlet pipe front end, nitrogen oxide sensor and block temperature sensor are fixedly connected on the top of shell.
Good effect of the present utility model is that it goes for four kinds of different reprocessing routes, part universality is good, process for machining and manufacturing is simple, arrangement is convenient, and assembly good reliability, possesses the feature that transformation efficiency is high, noise reduction capability is strong, back pressure is little, and add the intensity of processor assembly, also reduce the risk of end cap cracking simultaneously, improve the reliability of assembly, there is the very strong market competitiveness.
