Abstract

The invention discloses a rotary kiln dry distillation powder semi coke dry quenching and afterheat utilizing device and belongs to the field of semi coke processing devices. A high-temperature discharging valve (10) is arranged on the lower end of each discharge tube (11) of the rotary kiln (12), a high temperature resistant scraper conveyer (9) is arranged on the lower end of each high-temperature discharging valve (10), and a plurality of discharge holes (902) are formed at the bottom of the high temperature resistant scraper conveyer (9); the lower end of each discharge hole (902) is respectively and tightly connected with a spiral gate (8), a distributing device (7), a heat exchanger (6), a water cooling jacket (5) and a discharge valve (3); a conveyor (1) is arranged on the lower part of one row of discharge valves (3), and a material level detector (13) is arranged on the distributing device (7) or the heat exchanger (6) on the tail end. By adopting the device, the dry distilled semi coke in the rotary kiln can be dry-quenched and steam can be produced through semi coke sensible heat; the device has the advantages of large processing volume, low manufacture cost, reliability in operation, convenience in overhaul, and the like.

Description

technical field [0001] The utility model relates to a semi-coke CDQ and waste heat utilization device for dry distillation powder in a rotary kiln, which belongs to the field of semi-coke processing equipment. Background technique [0002] At present, my country's semi-coke production basically adopts internal heating vertical furnaces, and the annual output of a single furnace is mostly below 100,000 tons. After combining multiple furnaces side by side, it will reach the national access scale with an annual output of more than 600,000 tons. Due to the characteristics of this furnace type, pulverized coal and flour coal cannot be used to produce semi-coke, and the raw material must be lump coal of 20~80mm. With the mechanized mining of coal mines, the yield of lump coal is less than 30%, resulting in insufficient supply of lump coal raw materials, and a large amount of pulverized coal and flour coal cannot be used. The price of lump coal is at least 10% higher than that of ...
