Description
Technical field
The utility model relates to Vehicular exhaust post-processing technology field, relates in particular to a kind of selective catalytic reduction system operating.
Background technique
Along with the develop rapidly of national economy, people's living standard improves constantly, and is more and more higher to the pursuit of quality of life.Motor vehicle exhaust emission more and more receives common people's concern.Countries in the world are constantly strict to the emission request of diesel oil fuel-engined vehicle, promoting the development of engine technology, and improvement and the development of production firm to diesel engine particularly more and more paid attention to for the technical development of energy-saving and emission-reduction.At present, China realizes that the above exhaust treatment system major part of Euro IV Emission Standards is all take selective catalytic reduction (SCR) system as main flow.
The selective catalytic reduction system operating of prior art is modular structure, namely comprise independently urea box, independently electronic controller, independently urea pump, independently heat circulating system, these 5 assemblies of ejecting system independently, complete respectively after assembly again with its assembly unit, so workload is large, the space that most importantly takies is large, the installation of wire harness and pipeline is very difficult, completes this engineering very difficult in the very narrow and small automobile confined space.And manufacture cost is also relatively high.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of easy for installation, little and lower-cost selective catalytic reduction system operating takes up room.
The technological scheme that the utility model adopts is: a kind of selective catalytic reduction system operating, comprise urea box, urea pump, electronic controller, heat circulating system and ejecting system, described urea pump, electronic controller and heat circulating system be integrated being arranged on urea box all.
Adopt above structure compared with prior art, the utlity model has following advantage: with equal integrated being set on urea box of urea pump, electronic controller and heat circulating system, whole like this selective catalytic reduction system operating takes up room and greatly reduces, and do not need to carry out again assembly unit, so install also more conveniently, and cost is lower.
as preferably, described urea pump, electronic controller and heat circulating system all integrated being arranged on urea box refer to, described urea pump comprises the urea pump body, liquid level detected electrons pipe and urea supply pipe, described electronic controller comprises Electronic Control Box, described heat circulating system comprises one-way valve, heating pipe, the heating pipe base, water supply hose, electronic water valve and air filter, described urea box top is provided with the cavity of an accommodating urea pump body, described urea pump body is arranged in cavity, described liquid level detected electrons pipe, urea supply Guan Junyu urea pump body connects and is arranged in urea box, described heating pipe base is arranged on urea box top and described heating pipe is arranged in urea box, described one-way valve is arranged on urea box top, described urea box one side also is provided with one bent mouthful, described Electronic Control Box, electronic water valve and air filter are arranged in bent mouthful, described heating pipe is connected with water supply hose one end, the described flexible pipe the other end that enters is connected with electronic water valve, described electronic water valve, the urea pump body, liquid level detected electrons Guan Junyu Electronic Control Box is electrically connected to.Be arranged so that like this system height that original volumes is expanded is concentrated on urea box, pipeline connects convenient compactness, greatly reduced and taken volume, the urea pump body is directly embedded in urea box, make pipe-line system very simple, improved the working efficiency of system, Electronic Control Box is arranged on urea box one side, urea pump body, liquid level detected electrons pipe, electronic water valve are connected with Electronic Control Box and control all more convenient like this, air filter and one-way valve are arranged on urea box, so also can give easily system's air feed.
