| titleOfInvention | Rotary kiln device for sodium dichromate production by calcium-free calcination |
| abstract | The invention discloses a rotary kiln device for sodium dichromate production by calcium-free calcination, and belongs to the technical field of a rotary kiln. The length-diameter ratio of the kiln body is 3-6, wherein the feed end is provided with a feed port, a feed end burner and a smoke outlet, and the discharge end is provided with a siphon high-level outlet, a slag tap and a discharge end burner; a bottom blow-off nozzle device is arranged at the bottom of the kiln body, lateral blow-off nozzle devices are symmetrically arranged at two sides of the kiln body, a top blow-off nozzle device is arranged on the top of the kiln body, and the lengths of the arranged top blow-off nozzle device, the lateral blow-off nozzle devices and the bottom blow-off nozzle device are respectively 30 to 70 percent of the length of the kiln body; the top blow-off nozzle device, the lateral blow-off nozzle devices and the bottom blow-off nozzle device are horizontally arranged and respectively connected with a spray gun; and a power mechanism is arranged on the kiln body, and comprises a transmission device and a gear ring. According to the rotary kiln device, the oxidation reaction time is remarkably shortened, the production capacity is remarkably improved, the production cost is greatly reduced, and the chromite oxidation rate is high, so that an industrial scale can be easily formed. |
