Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Figure 1 to Figure 3 Schematically shows an exhaust catalytic flame arrester according to an embodiment of the present invention.

[0015] Such as image 3 As shown, the exhaust catalytic flame arrester provided by the present invention includes a flame arrester body 1, and the flame arrester body 1 includes a filter element 2 and flanges (3, 4) arranged on both sides of the filter element 2, and the four corners of the flange plate (3, 4) The two flanges (3, 4) are connected by bolts 5 and nuts 6, and there are multiple guide rods 7 between the two flanges (3, 4). The guide rods 7 are provided with compression springs 8, and the two ends of the compression springs 8 are set against the two flanges. (3,4) inside. The filter element 2 is sandwiched between the flanges (3, 4), and the filter element is arranged between the co...

Abstract

The invention discloses an exhaust catalyzed fire barrier which comprises a fire barrier body. A filter element is arranged inside the fiber barrier and is formed by coiling stainless steel bars and in a disc shape. Each stainless steel bar comprises dentiform steel bars and plate-shaped steel bars, and the dentiform steel bars and the plate-shaped steel bars are arranged alternately after been coiled into the disc shape. Catalyst cladding layers are arranged outside the dentiform steel bars and outside the plate-shaped steel bars in a plating mode. According to the exhaust catalyzed fire barrier, a precious metal catalyst layer is arranged on the filter element in a plating mode, HC and CO are made to be oxidized and generate water steam and CO2, NOx is reduced into nitrogen and oxygen, tail gas is purified, and environment pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment of coal mine transport vehicles, in particular to an exhaust catalytic flame arrester which has the function of purifying exhaust gas and can be quickly replaced. Background technique [0002] Explosion-proof rubber-tyred transport vehicles are the main auxiliary transport vehicles in coal mines. Due to the requirements of the underground environment, explosion-proof rubber-tyred transport vehicles need to have a fire-stopping function. At present, the exhaust catalytic flame arresters used on explosion-proof rubber-tyred transport vehicles only have Fire-stop function. However, the tail gas emitted by vehicles contains a large amount of pollutants, including three main pollutants HC (hydrocarbons), CO (carbon monoxide) and NOx (oxygen compounds). The underground space is small, and the exhaust gas cannot be diffused. The damage is greater. Contents of the invention [0003] In v...
