Abstract

The invention relates to a raw material premixing device for manufacturing denitrification catalysts. The raw material premixing device comprises a cone, wherein a motor is arranged in the middle of the upper part of the cone and is provided with a motor shaft, the motor shaft is connected with a metal rod, a long threaded rod and a short threaded rod are welded at the two ends of the metal rod, the upper part of the cone is further provided with a feeding port, the bottom of the cone is provided with a discharge port, a metal sleeve is arranged under the discharge port, and the cone is connected with a mixing mill by the metal sleeve. The raw material premixing device can uniformly mix raw materials, efficiently improve a mixing effect, and enhance production efficiency.

Description

technical field [0001] The invention relates to a raw material premixing device, in particular to a raw material premixing device used for the manufacture of denitration catalysts. Background technique [0002] The flue gas emitted by power plants contains a large amount of nitrogen oxides, which is one of the main sources of acid rain. The Ministry of Environmental Protection promulgated the "Emission Standards of Air Pollutants for Thermal Power Plants" in 2012, which set stricter requirements on the emission of nitrogen oxides. Among the many flue gas denitrification methods, selective catalytic reduction (SCR) is the most widely used and most effective flue gas denitrification technology. The catalyst is a vanadium-based catalytic system with nano-scale titanium dioxide as the substrate and vanadium pentoxide and tungsten trioxide as the active components. [0003] The general production process of denitrification catalyst monomer is raw material mixing, aging, filteri...
