Aluminum alloy honeycomb core flame arrester

Abstract

The invention provides an aluminum alloy honeycomb core flame arrester which comprises an exhaust entrance section, a flame arresting section and an exit section, wherein a rectangular flame arresting core is arranged inside the flame arresting section and adopts the structure that aluminum alloy corrugated plates are overlapped and spliced into a honeycomb airflow channel; the filling length of the rectangular flame arresting core in the airflow direction is 50-100 mm; the side length of the airflow channel of the rectangular flame arresting core is 0.5-1.5 mm; and the thickness of each aluminum alloy corrugated plate is 0.025-0.08 mm. The aluminum alloy honeycomb core flame arrester provided by the invention has the advantages that the airflow channel of the rectangular flame arresting core takes the shape of a honeycomb and the very thin aluminum alloy corrugated plates can be machined, so that the quantity of surfaces colliding with sparks in exhaust is increased, and then the flame arresting performance is better; and meanwhile, the wind resistance is low, the maintenance is easy and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of an explosion-proof diesel engine exhaust system for mines, and relates to a flame arrester, in particular to an aluminum alloy honeycomb core flame arrester with good flame arresting performance, small wind resistance and easy maintenance. Background technique [0002] The main means of transportation in coal mines are diesel engines. Due to the requirements of the underground environment, the explosion-proof performance of diesel engines has become very important, and the explosion-proof performance of diesel engines mainly depends on the performance of the flame arrester of the exhaust system. At present, the resistance of diesel engines used in mining Most of the firearms use flat and corrugated flame arresters, and most of the materials are made of ceramics or stainless steel. Although such materials have high rigidity and good quality, they also have problems. Not only the weight of the flame arrester...

Problems solved by technology

[0002] The main means of transportation in coal mines are diesel engines. Due to the requirements of the underground environment, the explosion-proof performance of diesel engines has become very important, and the explosion-proof performance of diesel engines mainly depends on the performance of the flame arrester of the exhaust system. At present, the resistance of diesel engines used in mining Most of the firearms use flat and corrugated flame arresters, and most of the materials are made of ceramics or stainless steel. Although such materials have high rigidity and good quality, they also have problems. Not only the weight of the flame arrester is heavy, but the flame arrester is very bulky ; Moreover, the wall of the fire-proof core is relatively thick, the air flow area is small, and the exhaust back pressure is large, resulting in a reduction in the power and economy of the explosion-proof diesel engine
