[0019] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the utility model is further explained in detail below in combination with specific implementation manners and referring to the drawings. It should be explained that the embodiment of the utility model and the features in the embodiment can be combined mutually in the case of not conflicting.

[0020] Some embodiments of the utility model provided by the utility model are described below in combination with the drawings.

[0021] Embodiment:

[0022] In combination Figures 1-4The utility model provides a special pipeline fire arrester of catalytic combustion equipment, including main body mechanism and cleaning mechanism, main body mechanism includes installation cavity 110, sets up the import 160 and export 161 of installation cavity 110 both ends, and the port of import 160 and export 161 all are installed with flange 170, the top of installation cavity 110 is installed with the closing plate 120, and the inside of installation cavity 110 is seted up and installs the mouth 130, and the inner wall of installation cavity 110 is installed with U piece 150, and the top of closing plate 120 and installation cavity 110 passes through bolt fixing, and the inside of U piece 150 is clamped with metal fire -arresting net 140, and the bottom of closing plate 120 is also installed with U piece 150, and the periphery of metal fire -arresting net 140 is clamped with a U piece 150 respectively, and cleaning mechanism includes the brush plate 210 of sliding connection in the side wall of installation cavity 110, the connecting rod 220 of fixed in the middle part of brush plate 210, and the pull hand 240 of with the top end of connecting rod 220 clamping, and the top end of connecting rod 220 passes through the end of closing plate 120 and is provided with the bolt 230, the bolt 230 is inserted with the pull hand 240, and the position of 120 connecting connecting rod 220 is provided with shaft seal 250.

[0023] Specifically, four U-shaped pieces 150 are installed on three inner walls of the installation cavity 110 and the bottom of the closing plate 120, respectively, thereby forming four corners distributed on four sides of the metal fire-arresting net 140, and thereby firmly fixing the position of the metal fire-arresting net 140 inside the installation cavity 110, avoiding the metal fire-arresting net 140 from deviating and causing gaps, so that the flame can not enter the flammable and explosive equipment, and the safety of the device is improved.
