Abstract

A semi-coke CDQ and waste heat utilization device for dry distillation powder in a rotary kiln belongs to the field of semi-coke processing equipment. A high-temperature discharge valve (10) is provided at the lower end of each discharge pipe (11) of a rotary kiln (12) , a high-temperature-resistant scraper conveyor (9) is provided at the lower end of each high-temperature discharge valve (10), and multiple outlets (902) are arranged at the bottom of the high-temperature-resistant scraper conveyor (9), and each outlet ( 902) the lower ends are respectively fastened in turn to connect a screw gate (8), a distributor (7), a heat exchanger (6), a water cooling jacket (5) and a discharge valve (3), in a row A conveyor (1) is provided below the discharge valve (3), and a material level detector (13) is provided on the distributor (7) or heat exchanger (6) at the end. The invention can CDQ dry-distilled semi-coke in a rotary kiln, and utilize sensible heat of the semi-coke to produce steam, and has the advantages of large processing capacity, low manufacturing cost, reliable operation, convenient maintenance 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 ...
