Description

The invention relates to mechanical engineering, in particular, engine-building, namely to spark control and an internal combustion engine.

The purpose of the invention is to increase the effectiveness of the spark arrester.

FIG. 1 and the proposed spark arrester, cut; in fig. 2 — node I in FIG. one; in fig. 3 - the node P in FIG. one; in fig. 4 is a section A-A in FIG. one; in fig. 5 - option spark arrestor as a waste heat boiler.

The I-scavenger includes a housing 1 equipped with a bottom 2, an inlet 3 with tangential and exhaust 4 axial nozzles and made in the form of a scroll, a coolant reservoir 5 with inlet 6 and a discharge nozzle 7 and a spindle-shaped sleeve 8 with a stem 9 installed in the outlet pipe 4 with the possibility of axial movement. In the housing 1 coaxially through the bottom 2 is installed ejecting pipe 10, forming an annular cavity with the housing 1 and a convex pipe 4 and equipped with baffles And, (one baffle) placed in the annular cavity of the housing 1, and a swirl 12 placed in the annular cavity of the exhaust pipe 4 The housing 1 is made of corrugated metal in the form of two truncated cones, conjugated with each other by large bases, provided with internal fins 13 placed between the AND baffle plates and the cleaning hole 14 in the bottom 2. ulka 8 and rod 9 is provided with a swirler 15 and placed in the ejecting nozzle 10, the coolant tank 5 is annular covering the lower cone of the body 1, and its conductive supply 6 and 7, the discharging nozzles mounted tangentially. The corrugation of the housing 1 is made in a bilateral rhombic or lentil form. The rod 9 of the sleeve 8 is installed in the uprights 16 and provided with a handle 17. When the sleeve 8 is installed in the ejecting nozzle 10, an adjustable annular channel a is formed. In the variant of the spark arrestor as a waste heat boiler (Fig. 5), the ejecting port 10 is made blind with its placement inside the housing 1.

Spark arrestor works as follows. in a way. X

Exhaust gases containing products of underheating come through inlet 3 to the inside of housing 1, where, swirling, they are somewhat inhibited by ribs 13, and the products of underheating go to the lower part of housing 1. Due to the presence of corrugations on the surface of housing 1, an additional " a wall vortex that does not immediately blow to the center of the stream, but remains pressed against the wall of the housing 1, which increases the heat transfer near the walls of the housing 1, while the exhaust gases are intensively cooled by a vortex fluid flow from the side of the tank 5 The bump stops 11 limit the release of under-gas products (sparks) into the outlet 4. Exhaust gases entering the housing 1 are partially supplied to the swirl 12, where they additionally swirl, then to the swirler 15 of the Viv exhaust sleeve 4. An adjustable annular channel a, formed in the ejecting pipe 10 by means of the sleeve 8, provides suction of atmospheric air, which

0 allows additional cooling of gases and the afterburning of sparks. In the event of air leaks from the cleaning room, additional ventilation is provided.

In the embodiment where the spark arrestor is used as a heat recovery boiler, intensive heat exchange in the housing 1 provides heating of the water or vaporization in the tank 5 of the cooling liquid.
