Abstract
The invention provides a double-divided sectional type heating odd horizontal flame path of a heat recovery coke oven, which belongs to the technical field of coke ovens and mainly solves problems of long smoke gas flowing path and large system resistance of the traditional heat recovery coke oven flame path as well as oven bottom temperature field distribution non-uniformity, coal cake heating non-uniformity and long coking time caused by incapability of adjusting combustion air in a sectional way and quantitively feeding the combustion air. The double-divided sectional type heating odd horizontal flame path is characterized by mainly comprising a falling vertical flame path, a central partition wall, an edge horizontal flame path, a middle horizontal flame path, converging horizontal flame paths, an air feeding pipe, an air adjusting device, a smoke gas outlet and so on, wherein an oven bottom horizontal flame path is partitioned into a machine side part and a coke side part by the central partition wall; the horizontal flame paths are communicated with each other in parallel, so as to respectively guide the smoke gas to the converging horizontal flame paths on the machine and coke sides; and air required to be combusted in each flame path is fed in a sectional way and can be singly adjusted. The double-divided sectional type heating odd horizontal flame path of the heat recovery coke oven, provided by the invention, has the advantages of short smoke gas flowing path, small system resistance, uniform oven bottom temperature field, reduction of coking time and so on.

Two fens horizontal quirks of zone heating odd number of heat recovery coke oven comprise the decline flue that is positioned at coking chamber wall, are positioned at air handling unit, the exhanst gas outlet at the gas inlet place, two fens horizontal quirks belows of cokery side; Also comprise center partition, the horizontal quirk in limit, by-level quirk, converge horizontal quirk, air infeeds pipe and air; Said decline flue is spaced apart along the coking chamber depth direction, and an end is communicated with coking chamber, and the other end is communicated with the side of the horizontal quirk in limit; Said center partition is positioned on the coke oven longitudinal cenlerline, is divided into the horizontal quirk of pusher side and the horizontal quirk of coke side two independent parts separately to horizontal quirk two, and every part has odd number Zhi Shuiping quirk; The horizontal quirk in said limit is arranged along the coking chamber depth direction, is positioned at the coking chamber below; Said by-level quirk is parallel with the horizontal quirk in limit, the horizontal quirk and converging between the horizontal quirk on the limit; Said converging on the coking chamber medullary ray that horizontal quirk is positioned at coking chamber below; Some Zhi Shuiping quirks are positioned at and converge horizontal quirk both sides, form the furnace hearth level quirk; The parallel also mutual side by side UNICOM of each horizontal quirk guides to horizontal quirk of converging of machine, coke side respectively with flue gas; Said exhanst gas outlet is arranged on and converges horizontal quirk machine, coke side end.
Said air arranges that along the segmentation of quirk length direction every quirk below is buried the some air that are parallel to quirk underground and infeeded pipe; Said air infeeds pipe one of which end and upwards feeds the quirk bottom, is air, and the other end is a gas inlet, is positioned at machine, the coke side end is connected with air handling unit, and every air infeeds pipe and can regulate the air amount of infeeding separately.
The present invention compared with prior art has following beneficial effect:
1, because the present invention adopts center partition that quirk is divided into machine, coke side two portions, adopt simultaneously and converge horizontal quirk the quirk of every side is divided into two portions once more, shortened flue gas flow;
2, because the present invention adopts the quirk segmentation air-supplied, the bottom temperature field distribution is even.
