Abstract

The invention relates to a pulverizer for desulfurization catalyst production. The pulverizer comprises a crushing barrel, a shaking device, a discharging barrel, an extruding device and a support, wherein the crushing barrel is transversely arranged, a feeding port is formed in the side wall of the crushing barrel and faces upwards, a screening plate is arranged on the side wall of the bottom of the crushing barrel, the bottom of the crushing barrel is arranged on the discharging barrel, one end of the crushing barrel is provided with the shaking device connected with the discharging barrel, the other end of the crushing barrel is provided with the extruding device connected with the discharging barrel, one end of the shaking device is provided with a motor, the motor is connected with a rotating shaft, the rotating shaft is arranged in the crushing barrel, and the rotating shaft is provided with a crushing arm. According to the pulverizer, the screening plate is directly arranged at the bottom of the crushing barrel for discharging, crushed materials are directly discharged, meanwhile, smooth discharging of the materials is achieved under rotation of the crushing arm, the problem that discharging of an existing transverse crushing barrel is difficult and not thorough is solved, and the discharging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a pulverizer for the production of desulfurization catalysts. Background technique [0002] With the continuous deepening of industrialization in various countries in the world, SO pollution has surpassed smoke pollution to become the largest pollutant in the atmospheric environment. Flue gas desulfurization (FGD) is different from other desulfurization methods. It is the only large-scale commercial application of desulfurization method in the world, and it is the most effective and main technical means to control acid rain and SO pollution. [0003] The surface of the desulfurization catalyst is active, can catalyze oxidation, can promote the direct reaction of SO2, accelerate the dissolution of CaCO, promote the rapid oxidation of CaSO to CaSO, strengthen the precipitation of CaSO, reduce the liquid-gas ratio, reduce the calcium-sulfur ratio, and reduce the evaporati...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims at the above-mentioned deficiencies in the prior art, and provides a pulverizer for the production of desulfurization catalysts. The bottom of the crushing barrel is directly provided with a sieve plate for discharging, and the crushed materials are directly discharged. The material can be discharged smoothly under the rotation of the arm, which solves the problem of difficult and incomplete discharge of the horizontal crushing barrel at present, and improves the discharge efficiency
