Black smoke burning and purifying apparatus for vehicle exhaust

Abstract

The present invention provides an improved black smoke burning and purifying apparatus for a vehicle exhaust comprising a burning system connected to intake of the exhaust and also to an emission smoke buffered filtering system. The emission smoke is guided into the burning chamber of the burning system and the fuel is atomized by a fuel atomized nozzle without being affected by the emission smoke. A pneumatic pump delivers air into the burning chamber to enhance burning and the emission smoke sequentially passes through buffering and filtering units of said buffered filtering system. Said buffering unit reduces flow rate of the emission smoke to prevent backflow from blowing off the spark. The emission smoke drives a turbine blade to force it pass through the filtering unit to burn off the carbon residuals thereof with the high temperature emission smoke to maintain proper emission of the exhaust of a diesel engine.

What is claimed is: 
     
         1 . An improved black smoke burning and purifying apparatus for a vehicle exhaust, comprising:
 a burning system comprising an external pipe with a burning chamber in an internal thereof; said internal of said external pipe comprising a cavity; a compartment of said cavity comprising an oil atomized nozzle and at least one igniter; wherein said oil atomized nozzle is fluidly connected to a fuel pump tank via a conduit, said compartment of said cavity is fluidly connected to a pneumatic pump via another conduit and said burning chamber of said external pipe is fluidly connected to an intake end of said vehicle exhaust;   an emission smoke buffered filtering system fluidly connected to said burning chamber of said external pipe and comprising an emission smoke buffering unit and a filtering unit arranged in sequence; wherein said emission smoke buffering unit comprises an emission smoke buffering shield and a turbine blade rotatably installed therein such that an emission smoke passing through said burning system sequentially enters into said emission smoke buffering shield to drive said turbine blade in rotation in order to force said emission smoke to pass through said filtering unit uniformly and to exit from an exhaust end of said vehicle exhaust.   
     
     
         2 . The improved black smoke burning and purifying apparatus for a vehicle exhaust according to  claim 1 , wherein said emission smoke buffering shield is a conical shield, and said conical shield comprises a conical wall with a plurality of through-holes formed thereon.
