Abstract

The invention relates to a selenium oxidation production device. The selenium oxidation production device comprises a forehearth generator, an oxidation furnace and a collecting box. The forehearth generator comprises a reaction cavity A, a feeding device is connected to the reaction cavity, and a heating assembly A for heating raw materials is arranged in the forehearth generator; the reaction cavity is communicated with the oxidation furnace through a connecting pipe A, a reaction cavity B is formed in the oxidation furnace, and a heating assembly B is arranged in the reaction cavity B; the collecting box is connected with the oxidation furnace through a connecting pipe B and comprises a collecting cavity, a cooling assembly is arranged on the outer wall of the collecting cavity, the collecting box further comprises a collecting assembly, a discharging device is connected to the bottom of the collecting box and comprises a discharging pipe, and a grinding device is arranged in the middle of the discharging pipe; a settling box used for settling dust is further connected to the collecting box, a settling discharging opening is formed in the bottom of the settling box, and a valve is arranged on the settling discharging opening.

Description

technical field [0001] The invention relates to a selenium oxidation production device, which belongs to a reaction furnace device. Background technique [0002] Domestic manufacturers of selenium dioxide basically use two kinds of production equipment: [0003] One is to weld the furnace body with stainless steel, feed the feed port and the furnace at the same time, oxidize twice, discharge once every two hours, low pass rate, low output, serious pollution, and the operator is easy to inhale selenium dioxide when discharging Dust, and the coarse selenium raw materials produce chloride ions and selenous acid to corrode the furnace body when heated at high temperature, and the furnace body needs to be repaired in at most two months. Superficial skin damage. [0004] The other is to weld the stainless steel cylinder outside and add refractory bricks to keep it warm. Once the material is fed for four days, it will be discharged. Once the temperature is out of control, most of...
