Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a coal-fired boiler flue gas denitrification catalyst separation device. Background technique [0002] In a chemical reaction, the catalyst must keep in good contact with the reaction medium, so mechanical stirring or air blowing stirring is generally used in the reactor to promote the continuous renewal of the surface of the catalyst particles and the surface of the reactants, and the catalyst particles are in a suspended flow state in the reactor . The whole process is continuous production. After the reactants are converted into products, they are discharged from the reactor, and then the catalyst particles are also taken out of the reactor along with the products. In order to recycle the catalyst, solid-liquid separation must be carried out. Filtration and pressure filtration are generally used. During filtration, with the formation of filter cake, the resistance...
