Abstract

The invention relates to a furnace liner for a vertical coal mine ventilation air methane oxidation device. The furnace liner is characterized by comprising a shell, a ceramic fiber blanket, an anchoring piece, and a wall body consisting of short ceramic fiber modules, long ceramic fiber modules and compensation blankets, wherein the upper and lower ends of the short ceramic fiber modules are provided with the compensation blankets; the upper and lower ends of the long ceramic fiber modules are provided with the short ceramic fiber modules with the compensation blankets; one side of the wall body is provided with the ceramic fiber blanket, while the other side is sprayed with a fireproof paint; and the shell is fixed on the side, which is not coated with the fireproof paint, of the wall body by the anchoring piece. The furnace liner has the advantages of good heat insulation effect, flat surface, light weight, low cost, convenient installation and the like.

Description

technical field [0001] The invention relates to a furnace lining of a vertical coal mine exhaust air gas oxidation device, belonging to the technical field of ultra-low concentration methane thermal countercurrent oxidation. Background technique [0002] The main component of gas is methane, which is the biggest safety hazard in coal mine production. In order to improve the safety of coal mine production, a large amount of ventilation is usually used to discharge coal mine gas (called coal mine exhaust), which not only causes a lot of energy waste, but also seriously pollutes the atmospheric environment. The concentration of methane in coal mine exhaust air is very low, generally less than 0.8%, and cannot be burned by traditional burners. The current effective utilization method is to use thermal countercurrent oxidation technology to oxidize methane in exhaust air into carbon dioxide and water. The heat released in the oxidation process is not only used to maintain the op...
