Abstract
The invention provides an intake device for a DEP (diesel exhaust particles) automobile exhaust purifying system. The intake device comprises a rough filter connected with an intake cylinder; an equalizing plate is connected to the rear end of the rough filter and comprises a central portion and a peripheral portion; both the central portion and the peripheral portion are both provided with through holes; the through holes of the central portion are larger than the those of the peripheral portion. The rough filter is used to filter larger dust particles and protect a DEP purifying processor. Air flow passing by the central portion of the equalizing plate experiences large resistance, the air flow passing by the peripheral portion of the equalizing plate experiences small resistance, air flow density is accordingly adjusted, automobile exhaust smoothly and evenly flows through the purifying system, and purifying efficiency is improved.
Description
Technical field
The invention belongs to purifying vehicle exhaust processing technology field, be specifically related to a kind of inlet device of DEP 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.
Summary of the invention
In order to overcome the defect existed in above-mentioned prior art, the object of this invention is to provide a kind of inlet device of DEP automobile tail gas purification system.
The invention provides a kind of inlet device of DEP 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 present invention adopts rough filtering device to filter larger dust granules, shields to DEP purifying processor.In addition, the present invention 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.
Present invention also offers a kind of inlet device of DEP automobile tail gas purification system, comprise the rough filtering device be connected with air induction mast, the rear end of described rough filtering device connects homogenizing plate, and described homogenizing plate is distributed with through hole, from the direction at sensing edge, homogenizing plate center, the diameter of described through hole becomes large gradually.
The present invention adopts rough filtering device to filter larger dust granules, shields to DEP purifying processor.In addition, the present invention is by adopting homogenizing plate, and the resistance be subject to by the air-flow of homogenizing plate middle body is maximum, move along with to edge, the resistance be subject to reduces gradually, thus adjusts current density, vehicle exhaust is made to flow evenly through cleaning system gently, to improve purification efficiency.
Preferably, described rough filtering device is filter cloth.With low cost, structure is simple.
Additional aspect of the present invention and advantage will part provide in the following description, and part will become obvious from the following description, or be recognized by practice of the present invention.
