Catalyst catalysis ware of silencer

The utility model provides a catalyst catalysis ware of silencer, the catalyst catalysis ware include a lesson outer tube, it restraints and to restraint with the second catalyst to be equipped with first catalyst in the outer tube, between restrainting and to restraint, first catalyst is equipped with a wadding class hybrid chamber with the second catalyst, third to the fifth that length that thewadding flows the hybrid chamber was restrainted at first catalyst. The utility model has the advantages of the single section catalyst adopts inside cavity, and waste gas is restrainted after through from first catalyst and is formed the turbulent flow at the cavity position, makes the abundant mixture of waste gas, restraints from the second catalyst and gets rid of, the further conversion efficiency that improves. Under the condition of a small amount of incremental cost, increaseed the surface area of catalyst, make conversion area grow, improve the conversion rate. 种消声器的触媒催化器，所述的触媒催化器包括节外管，所述外管内设有第触媒束和第二触媒束，所述第触
