Rapid combustion, purification and regeneration device for black smoke and exhaust gas discharged by vehicles

Abstract

The invention discloses a rapid combustion, purification and regeneration device for black smoke and exhaust gas discharged by vehicles. A gas inlet unit, a combustion unit, a buffer propagating combustion unit, a filter unit, a discharge unit and an automatic control unit are arranged in sequence; the exhaust gas is fed in a combustion cavity in the combustion unit via the gas inlet unit; after fuel is ejected and atomized by a fuel atomizing nozzle not blown by an exhaust gas current, an igniter is immediately fitted for igniting and combusting, and air is input in the combustion cavity for supporting the combustion by using an air pressure pump; the high-temperature exhaust gas is passed through a filter buffer chamber and a propagating combustion chamber of the buffer propagating combustion unit in sequence; the filter buffer chamber is used for primarily filtering the exhaust gas and slowing down the flowing speed of the exhaust gas so as to prevent the backflow of the exhaust gas to blow out the ignited flame; the exhaust gas is fed in the propagating combustion chamber to reduce the backtracking pressure of the exhaust gas, and then is passed through the filter unit and an exhaust tail pipe; and the high temperature of the exhaust gas is used for removing carbon deposition of the filter unit so as to maintain the discharge smoothness of the exhaust gas of a diesel engine.

Description

technical field [0001] The invention relates to a device capable of quickly burning and removing carbon deposits in a filter device installed at the rear end of an exhaust pipe of a diesel engine, purifying and regenerating them, so as to maintain the diesel engine's smooth discharge of exhaust gas. Background technique [0002] After the exhaust gas emitted by the diesel vehicle engine passes through the filter system, carbon deposits will be generated in the filter element of the filter system. When the carbon deposit reaches a certain thickness, it will cause blockage, resulting in an increase in the pressure (back pressure) in the exhaust pipe. Therefore At present, the automobile industry installs the back pressure sensor in the exhaust pipe of the diesel vehicle engine to detect the pressure value at the filter element of the filter system, and then can detect the blocking state of carbon deposits. Once the exhaust gas emitted by the diesel vehicle engine passes through...

[0007] Another purpose of the present invention is to improve the exhaust gas in the Chinese Utility Model No. ZL201220188915.6 patent case. The exhaust gas will be blocked by structures such as fuel atomization nozzles, resulting in unsmooth air conduction and incomplete combustion, easy flameout, and combustion. The speed of removing carbon deposits and removing heat from exhaust gas is not fast enough
