Abstract
The utility model relates to a flue shutter of a cleaning type heat recovery coke furnace; the flue shutter comprises a flue shutter framework (1), a flue shutter framework (2), a flue shutter framework (3), a flue shutter framework (4), a flue shutter framework (5), a flue shutter framework (6), a flue shutter framework (7) and a flue shutter framework (8); the structure of a main body is made of a novel heat resistant steel body; the eight flue shutter frameworks made of the same material are connected through coupling bolts; and braided asbestos round packing is arranged in connecting gaps of the flue shutter frameworks. The coupling bolts are made of heat resistant cast steel; and a pouring layer is made of a novel refractory castable. Due to the improvement of the structure material of the flue shutter and the refractory castable material, the flue shutter has the quenching and quick heating resistance performance and long term high-temperature resistance performance and does not deform and fracture in high temperature, the probability that wastes are discharged at random as the flute shutter suddenly fractures and falls into a flue is reduced, the frequency of replacing and overhauling the flue shutter is reduced, and the economic benefit and social benefits of enterprises are increased.
Description
Technical field
The utility model belongs to a kind of coke oven flue flashboard, is specifically related to a kind of clean type heat reclamation coke furnace main flue channel flashboard.
Background technique:
At present, environmental requirement both at home and abroad improves constantly, vigorously advocate and make " low-carbon (LC) " industrial and mining enterprise, Shanxi Province in 2000 chemical design institute's independent research environment protection effect QRD-2000 clean type heat recovery tamping type coke oven preferably.The clean type heat recovery tamping type coke oven of building that started both at home and abroad till now from 2000 has family more than 100, but this type of furnace belongs to negative-pressure operation, and flue suction force is regulated frequent; The flashboard structure material of control flue suction force size requires high, and this technology belongs to a kind of new things, new technique simultaneously, and is not overripened; The flue shutter structure adopts plain cast iron and common pouring material be combined into always; Anti-rapid heat cycle property is low, and flue is fallen in the fracture of flashboard partial structurtes appearance often in the production operation process, and influence is produced; Cause the Litter uncontrollable discharge, pollute environment, increase the maintenance amount of labour, strengthen the business economic input cost.
Summary of the invention:
The utility model is exactly will solve that the existing anti-rapid heat cycle property of clean type heat recovery tamping type coke oven flue shutter structure material is low, easy-rupturing, change the problem of flue shutter, uncontrollable discharge Litter often.
The utility model is realized through following technological scheme: a kind of clean type heat reclamation coke furnace flue shutter; Form by the first flashboard framework 1, the second flashboard framework 2, the 3rd flashboard framework 3, the 4th flashboard framework 4, the 5th flashboard framework 5, the 6th flashboard framework 6, the 7th flashboard framework 7, the 8th flashboard framework 8; The agent structure material is the New Heat-Resistant Steel body; 8 flashboard frameworks with material connect through attachment bolt, and the connection gap of flashboard framework is provided with braided asbestos round packing.The attachment bolt material is a heat resisting cast steel; Pouring layer adopts novel castable refractory.
The utility model compared with prior art has following beneficial effect: through the improvement of flashboard structure material and castable refractory material; Make flashboard increase anti-rapid heat cycle performance; Increase long-term resistance to high temperature, high temperature is indeformable, do not rupture, and reduces the probability that stack gases thing uncontrollable discharge is fallen in flashboard burst fracture; Reduce and change flashboard, maintenance number of times, improve the performance of enterprises and social benefit.
