SU428102A1 - DEVICE FOR EXHAUST SYSTEM INTERNAL COMBUSTION ENGINE - Google Patents

Description

one

The invention relates to the field of mechanical engineering and is intended for exhaust systems of internal combustion engines and mostly diesel engines.

Devices for the exhaust system of an internal combustion engine are known, comprising a swirler arranged in a housing with a screen forming a confuser channel with sepa lattices and a drainage line.

The known devices have either large dimensions to increase the flow path of the Exhaust gas, or are ineffective in separating the liquid, solid and gaseous phases, "which are present in the exhaust gases of the engines.

In order to improve the effectiveness in the proposed device, the swirler and the screen form a cavity divided by the perforated wall and communicated with the drainage line.

In addition, in the proposed device, the cavity can be made in the form of a cylinder or in the form of a cone.

The drawing shows the proposed device for the exhaust system of the internal combustion engine.

It contains. Case 1 with inlet 2 and outlet 3 nozzles.

In the housing 1 there is a swirler 4 with a screen 5, which forms with the separation grids 6 ″ an infuser channel 7 and is connected to the drainage line 8 a separation chamber 9.

The swirler 4 and the screen 5 form a cavity 10, divided by a partition 11 and communicated with the drainage line 8 by the pipeline 12.

In the output latrubka 3, additional air grids 13 and a separator chamber 14 connected by channels 15 with a cavity 10 can be placed.

During operation, exhaust gases from the inlet nozzle 2 enter the body / on the swirler 4, where they acquire a rotational movement, which facilitates the separation of the flow into the liquid, solid and gaseous phases.

The solids are abraded in the spark trap, and the liquid phase through the separation slats} 6 and separation chambers 9 is discharged into the drainage line 5.

Partially cleaned gases enter the cavity 10, where the d-additional purification of them from the solid phase occurs by abrasion on the inside of the screen 5. The liquid phase is drained along the inside of the screen under the perforated partition 11 and discharged through the pipe 12 into the drainage pipe 8.

Gases from the casing / are directed to the outlet 3, where they can be subjected to additional cleaning on separated grates 13.

Separated; the phase from separation chamber 14 passes through channels 15 into cavity 10 and then pipe 12 into drainage line 8. Purified exhaust gases are discharged from the housing / through pipe 3.
