Description

The invention is a vortex spark arrestor for extinguishing solid particles from the combustion products of internal combustion engines.

Existing vortex spark arrestors, fiberguns with nets, labirites, and the use of cameras with irradiation cameras, have the following essence and residues; dust together with a stream of fresh air, falling into the exhaust pipe, creates additional sparking; And the dust burnt in the exhaust pipe contributes to more inteisigzioma soot complication in the labyrinths and spark arresting chambers. The transition from manual operation to the cleaning of the air purifier play ик stage of the air cleaner from the engine and the device, which became 11rim. To take place later, is complicated by the fact that instead of the buiker it is much more likely to clean the spark arrester from both the soot and the soot, and resulting from burnt and coked dust.

In the spark arrestor according to the invention, these disadvantages are eliminated by that. that the internal and surface sparks do not have labyrinths or chambers where fats could accumulate; a; in this spark arrest, by combining the loiast direction I, its apparatus (impellers) of the tangential inlet for exhaust gases with the cone (after the exhaust gases exit the impeller) creates a continuous increase in the exhaust flow of centrifugal force, providing crushed particles of sparks.

The drawing shows the device spark arrester.

At the end of the engine exhaust pipe, in the combustion (1) are installed: impeller (2) (with several loiatkamn, equidistant from the circumference), a hollow cone-shaped body (3) and a protective cap (4). These parts are tightened, sealed and fixed with the help of the rod (5) and gaskets (6) (for example, from an asbestos cord).

Pskra saturated exhaust gases. entering the impeller through the exhaust pipe, change the direction of the noto1; a l. acquiring a rotational D 1n: ken1k in it is directed to the ground cone-shaped body (3). Subsequently, the BL emitting the rotational motion of the current of a cone, the speed and, consequently, the centrifuge, and the force of the solid particles of the exhaust gas flow continuously increases as it reaches the outlet to the atmosphere. Two particles of exhaust gases occur on the helix (pe wall cone forming), which significantly increases the path of movement of the spark and its core with its inner surface. During the time of the rotor in the cone, they are triturated on its inner surface, crushed, giving off heat, and extinguished.

Power absorbed by the conical nskrogasitedem and exhaust pipe, such

the same as for the other nasvrogasgel; i is 0.4: 0.6 l. with.

A double cone can be used instead of the impeller, providing a tangential intake of exhaust gases into the spark arrester's corius.

The proposed vortex spark arrester can be installed on the engines of self-propelled machines, as. an anti-fire agent and, as an ashtarate, allowing / using an auxiliary device i ITC;) air purifier level.

Subject invention

Vortex spark arrestor for extinguishing solid particles of combustion products of internal combustion engines, which is necessary in order to effectively extinguish and comminate unburned particles, to the products of combustion of itx from the exhaust pipe from the pilot-blade pilot air or tangential entry is imparted by a vortex spiral motion along the walls of the cone.
