Abstract
The utility model proposes a kind of inlet device of automobile tail gas purification system, it comprises the rough filtering device be connected with air induction mast, the rear end of rough filtering device connects homogenizing plate, homogenizing plate comprises middle body and periphery, middle body and periphery are distributed with through hole, and the clear size of opening of middle body is less than the size of periphery through hole.The utility model adopts rough filtering device to filter larger dust granules, shields to DEP purifying processor.The utility model is by adopting homogenizing plate, the resistance be subject to by the air-flow of homogenizing plate middle body is large, and the resistance be subject to by the air-flow of homogenizing plate periphery is little, thus adjusts current density, vehicle exhaust is made to flow evenly through cleaning system gently, to improve purification efficiency.
Description
Technical field
The utility model belongs to purifying vehicle exhaust processing technology field, is specifically related to a kind of inlet device of automobile tail gas purification system, before being arranged on DEP purifying processor.
Background technique
Along with socioeconomic development, consumption and the pollutant discharge amount thereof of one side fossil energy constantly raise, and on the other hand, in order to more live, people require more and more higher to clean environment degree healthiness.In order to tackle the environmental problem that high pollution brings, country proposes more and more stricter requirement to the discharge of vehicle exhaust.In order to realize the exhaust emissions of lower concentration, current Purification approach is divided into emission controls by improving combustion and external purification two kinds, emission controls by improving combustion is the growing amount in order to reduce harmful gas, before vehicle exhaust enters air, utilizes catalytic convention design to be translated into innocuous gas; External purification purifies through row relax after discharging waste gas, as adopted the methods such as air injection, oxidized form reactor and three-effect catalysis reactor.But these methods are all the purified treatment done for NOx, HC, CO, at present also not to the gathering-device of PM in vehicle exhaust (particulate matter).
In addition, the flow velocity of vehicle exhaust is generally at 0.15-1.5m/s, and the graphic memory in vertical flow velocity direction is in the phenomenon of mass flow discrepancy, therefore, need to design the entrance of cleaning system, make vehicle exhaust flow evenly through cleaning system gently, to improve purification efficiency.
Model utility content
In order to overcome the defect existed in above-mentioned prior art, the purpose of this utility model is to provide a kind of inlet device of automobile tail gas purification system.
The utility model provides a kind of inlet device of automobile tail gas purification system, comprise the rough filtering device be connected with air induction mast, the rear end of rough filtering device connects homogenizing plate, described homogenizing plate comprises middle body and periphery, described middle body and periphery are distributed with through hole, and the clear size of opening of described middle body is less than the size of described periphery through hole.
The utility model adopts rough filtering device to filter larger dust granules, shields to DEP purifying processor.In addition, the utility model adopts homogenizing plate, and the resistance be subject to by the air-flow of homogenizing plate middle body is large, the resistance be subject to by the air-flow of homogenizing plate periphery is little, thus current density is adjusted, make vehicle exhaust flow evenly through cleaning system gently, to improve purification efficiency.
Preferably, described rough filtering device is filter cloth.With low cost, structure is simple.
Preferably, the clear size of opening of described homogenizing plate middle body is equal, and the clear size of opening of described homogenizing plate periphery is equal.Preparation process is simple.
