Abstract

The invention provides a mining hydrogen fuel cell automobile exhaust hydrogen removal device which comprises a catalysis pipeline, wherein automobile exhaust is introduced into the catalysis pipeline; an outer layer of the catalytic pipeline is of a net-shaped structure, an inner layer is provided with an ion transmission interface film, and the exterior of the catalytic pipeline is immersed in water, so that the water penetrates through the net-shaped structure to be connected with the ion transmission interface film; and the ion transmission interface film comprises an ion migration layer, a hydrogen molecule adsorption layer and a hydrolysis layer, the hydrogen molecule adsorption layer and the hydrolysis layer are compounded on the two opposite faces of the ion migration layer, and water dipping the catalysis pipeline penetrates through the net-shaped structure to be connected with the hydrolysis layer. On the basis of an ion transport interface membrane catalysis technology, a novel loop membrane interface catalytic oxidation device is designed, fuel cell stack waste heat is used as a catalytic heat source, and low-concentration hydrogen in tail gas is efficiently and thoroughly removed. A mining hydrogen fuel cell automobile exhaust hydrogen removal method provided by the invention has the advantages of simple structure, thorough hydrogen removal, wide application range and no extra energy consumption, and is suitable for popularization and application of hydrogen fuel cell automobiles in underground and above closed spaces.

Description

technical field [0001] The present application relates to the technical field of surface catalysis of electrochemical materials, in particular to a device and method for dehydrogenating hydrogen fuel cell vehicle tail gas used in mines. Background technique [0002] Underground trackless auxiliary transport vehicles in coal mines are the largest field of vehicle use in underground mines. At present, the commonly used trackless auxiliary transport vehicles are diesel vehicles and lithium iron phosphate electric vehicles. Both types of vehicles have serious shortcomings. Incomplete combustion of diesel vehicles produces a large amount of CO and SO 2 and NO x , The discharge of these gases in the underground confined space causes serious pollution, which limits the life safety of miners and normal safe production. Lithium iron phosphate electric vehicles take a long time to charge and cannot work continuously. In addition, lithium iron phosphate batteries are heavy and usuall...
