Abstract
The utility model provides an upper furnace door for a clear type heat recovery coke furnace. The upper furnace door comprises a furnace door body (1) and three detachable accordion cast iron lower edges (2), wherein the furnace door body (1) is provided with an arc section, the arch section is provided with a semicircular groove (3) in which a braided asbestos round packing is arranged, and the detachable accordion cast iron lower edges (2) are connected with the furnace door body (1) through heat-resistance bolts. According to the utility model, based on the improvement in the furnace door structure and fire-retarding pouring layer material, the sealing form of the upper furnace door is changed to a flexible sealing form, and therefore the current situations of poor sealing effect, serious leakage, unorganized air supply of the coke furnace and large cooling quantity caused by hard face contact, coke rate is reduced, waste heat utilization and full coke yield are improved and resource waste is hardly caused; the frequency of replacement of the whole upper furnace door, caused when the lower edge of the upper furnace door is burnt out, can be reduced, only the detachable cast iron lower edges need to be replaced if the lower edge is burnt out, and therefore the economic and social benefits of enterprises can be improved.
Description
Technical field
The utility model belongs to a kind of coke oven upper furnace door, is specifically related to a kind of clean type heat reclamation coke furnace upper furnace door.
Background technology:
By Shanxi Province in 2000 chemical design institute's independent research environment protecting QRD-2000 clean type heat recovery tamping type coke oven preferably, this type of furnace belongs to negative-pressure operation, the body of heater coking chamber is wide, high; The furnace insulation effect requirements is high, and oven door sealing requires tight, and is simultaneously should technology not overripened; Oven door sealing adopts rigidity to seal firmly always, and sealing effectiveness is poor, since dropping into operation, has occurred from fire door unorganized air supply amount big; The fire door surface temperature is high, and the upper and lower edge of fire door is prone to scaling loss and comes off the frequent change fire door; Vicious cycle aggravates air output and changes burnt serious problem, has caused the wasting of resources and business economic benefit to reduce.
Summary of the invention:
The utility model be exactly to solve existing clean type heat recovery tamping type coke oven upper furnace door sealing effectiveness poor, reveal serious, heat dissipation capacity is big, the upper furnace door lower edge is prone to scaling loss, the frequent change upper furnace door, change burnt serious problem.
The utility model is realized through following technical scheme: a kind of clean type heat reclamation coke furnace upper furnace door; Fire door is made up of oven door body 1 and 3 detachable folding shape cast iron lower edges 2; Oven door body 1 is provided with segmental arc, and segmental arc is provided with half-arc groove 3, is provided with braided asbestos round packing in the half-arc groove 3; Detachable folding shape cast iron lower edge 2 connects with fire door main body 1 through heat-resisting bolt.
The utility model compared with prior art has following beneficial effect: through the improvement of door structure and refractory casting layer material; Make the oven door sealing form change flexible sealing into; Thereby change rigid contact seal tight, reveal serious, coke oven unorganized air supply, present situation that heat dissipation capacity is big; The burnt rate of reductionization improves UTILIZATION OF VESIDUAL HEAT IN and full coke yield, the less wasting of resources; Reduce simultaneously because of upper furnace door lower edge scaling loss, and change the number of times of whole upper furnace door, the detachable folding shape cast iron lower edge of only changing of scaling loss lower edge gets final product, and has improved business economic benefit and social benefit on the whole.
