Movable slide bed tunnel type coke oven and use method thereof

Abstract

The invention relates to a movable slide bed tunnel type coke oven and a use method thereof, and belongs to the field of coal processing and conversion and coking equipment. The coke oven comprises an oven body (48), a front sealing door (7) of the coke oven body, a back sealing door (25) of the coke oven body, a sub-flue (10), a bottom flue (12) and a main flue (6), and is characterized by comprising a coaling preparation chamber (3), a preheating section (50), a carbonization section (51), coke dry quenching section (52) and a coke outlet preparation chamber (23), each part has different structures, and the five parts are connected in series and communicated with each other; and a movable slide bed (37) of loading briquettes or tamping coal materials (44) sequentially pass through the five parts of the coke oven by intermittently moving on a slideway (35) of the slide bed, so that the coal materials are carbonized into coke. The produced coke has uniform specification, large lumpiness, good strength, high heat energy utilization rate, high degree of mechanization, and clean emission of flue gas, and the invention effectively protects atmosphere and water sources and realizes clean production.

Description

technical field [0001] The invention belongs to the field of coal processing and conversion and coking equipment, and specifically relates to a coking that adopts a movable slide bed, can be continuously mechanized, can produce molded coke and stamped coke, and can recover chemical products and use waste heat to generate electricity Furnaces and methods of use. Background technique [0002] The existing coking technology in my country mainly adopts conventional mechanical coke ovens with chemical product recovery, top loading or tamping side loading. Its defects are strong dependence on coking coal, high cost of raw materials, uneven coke specifications and small lumps, The unorganized escape of raw gas exists in the operation. There are also some heat recovery coke ovens that do not recover chemical products, but the heat recovery coke ovens have the problem of long coking time, the inability to precisely control the production temperature and speed, and it is difficult to ...

Problems solved by technology

Although this kind of furnace body is said to divide the entire furnace body into a drying section, a dry distillation section and an air cooling section, in fact, the furnace body is simply divided according to the temperature and the state of the coal material, and the temperature of the drying section is only determined by the temperature difference between the dry distillation section. Natural conduction, slow drying speed affects output; air cooling section relies on red coke gas exhaustion, natural cooling, and there is no accurate distinction on the furnace body

In this patent, due to the inability to completely seal between kiln cars, the bottom of the kiln car and its surroundings, gas and chemical products cannot be recovered, and there are also disadvantages of unreasonable utilization of heat energy, slow coking speed, and low output.
