Abstract
The utility model discloses a selective catalytic reduction converter. The utility model aims to design a selective catalytic reduction converter that has a good filtering effect for automobile exhaust. The technical scheme provided by the utility model is that the selective catalytic reduction converter comprises a urea generating tank and a silencer, wherein the urea generating tank is arranged on a pipeline, the pipeline enters into a reaction chamber, the reaction chamber is connected with a reduction converter through the pipeline, the reduction converter is connected with the silencer through the pipeline and the silencer is connected with an exhaust pipe. The selective catalytic reduction converter provided by the utility model has a reasonable structure, can be used to treat the automobile exhaust environment-friendlily and efficiently, and meets the emission requirement of the automobile exhaust.
Description
Technical field:
The utility model relates to the vehicle exhaust filtering technique, particularly a kind of selective catalytic reduction converter.
Background technique:
Present progress and development along with society; The owning amount of automobile is more and more; And the emission of automobile wastes amount is also very big, and the harmful matter in the motor exhaust is a lot, can have a strong impact on environment; Therefore, the exhaust emissions that how to reduce motor car engine is present development, research direction to the harmful matter in the atmosphere.
Summary of the invention:
The purpose of the utility model is a kind of selective catalytic reduction converter to the vehicle exhaust good filtration effect of design.
The technological scheme of the utility model is, a kind of selective catalytic reduction converter, and it comprises the urea generation tank; Silencing apparatus; It is characterized in that: on pipeline, be provided with the urea generation tank, pipeline feeds reaction chamber then, and reaction chamber is connected through pipeline with the reduction converter; The reduction converter is connected through pipeline with silencing apparatus, and silencing apparatus is connected with outlet pipe.
The utility model is rational in infrastructure, can carry out environmental protection, handle efficiently vehicle exhaust, satisfies the emission of automobile wastes requirement.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Describe embodiment in detail in conjunction with accompanying drawing, the concrete structure of the utility model is a kind of selective catalytic reduction converter; It comprises urea generation tank 1, and silencing apparatus 4 is provided with the urea generation tank on pipeline; Pipeline feeds reaction chamber 2 then; Reaction chamber is connected through pipeline with reduction converter 3, and the converter that reduces is connected through pipeline with silencing apparatus, and silencing apparatus is connected with outlet pipe 5.The utility model is used the urea generation tank, and aqueous solution of urea is sprayed in the pipeline, and the urea posthydrolysis of being heated becomes ammonia, and ammonia reacts in the reduction converter for the nitrogen oxide type compound in the tail gas, generates nontoxic nitrogen G&W, again through the outlet pipe discharge; And the utility model is provided with silencing apparatus, has reduced exhaust sound.The utility model is handled the vehicle exhaust environmental protection, and is efficient, guaranteed that vehicle exhaust reaches emission standard.
