The invention discloses a rotary type rotary furnace. At least one movable partition plate assembly and / or at least one fixed partition plate is arranged in a roller, the fixed partition plate is fixed in the roller, and an opening is formed in the position, close to the inner wall of the roller, of the fixed partition plate; and the movable partition plate assembly comprises a partition plate and a movable baffle, wherein the partition plate is fixed in the roller, an opening is formed in the position, close to the inner wall of the roller, of the partition plate, and the movable baffle is movably connected with the partition plate through a baffle driving device, can move relative to the partition plate and is used for sealing the opening of the partition plate. According to the rotary type rotary furnace, the fixed partition plate and the movable partition plate assembly can enable solid-phase materials to move in the roller through the opening and limit convection between different process sections of the gas-phase materials in the roller, the temperature gradient between different process sections is improved, and the reaction requirements of different processes are met.
Description
technical field [0001] The invention relates to the technical fields of environmental protection, energy and chemical equipment, in particular to a rotary rotary kiln. Background technique [0002] In environmental protection, energy, and chemical production, the conversion process of some materials often needs to go through processes such as pyrolysis, gasification, carbonization, activation, reaction, and cooling, and these processes are generally carried out by different rotary rotary kilns, or in the same In the rotary rotary kiln, several processes are gradually completed during the process of material moving from the feed end to the discharge end. [0003] The existing rotary rotary kiln mainly includes a drum and a driving device. The feeding end of the drum is higher than the discharging end of the drum. The drum is driven by an external driving device to continuously rotate, and the material is turned from the feeding end to the drum while turning inside the drum. ...
