Abstract
The invention provides an upper furnace door of a clean heat recovery coke oven. The upper furnace door comprises a furnace door body (1) and three detachable zigzag-form cast iron lower edges (2), wherein an arc segment is arranged on the body (1) and is provided with a semicircular groove (3), an asbestine circular rope is arranged in the semicircular groove (3), and the detachable zigzag-form cast iron lower edges (2) are connected with the furnace door body (1) through heatproof bolts. According to the invention, through improvement of the structure of the furnace door and the material of a fireproof casting layer, the sealing mode of the furnace door is changed into flexible sealing, so the problems of poor sealing, severe leakage, unorganized air supply for the coke oven and great amount of heat dissipation of current rigid surface contact are overcome, the rate of non-fully coked char is reduced, waste heat utilization and total char yield are improved, and less resources are wasted; meanwhile, frequency of replacing of the whole upper furnace door due to burnt lower edges of the upper furnace door is reduced, and it only needs to replace a burnt lower edge with the detachable zigzag-form cast iron lower edge, so economic benefits and social benefits of an enterprise can be improved.
Description
Technical field
The invention belongs to a kind of coke oven upper furnace door, be 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, oven door sealing requires tight, this technology is not overripened simultaneously, oven door sealing adopts rigidity firmly to seal always, sealing effectiveness is poor, has occurred since dropping into operation from fire door unorganized air supply amount greatly, and the fire door surface temperature is high, on the fire door, the easy scaling loss in lower edge comes off, the frequent 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 present invention 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 large, under the upper furnace door along easily scaling loss, frequent upper furnace door, change burnt serious problem.
The present invention is achieved through the following technical solutions: a kind of clean type heat reclamation coke furnace upper furnace door, fire door is by forming along 2 under oven door body 1 and 3 blocks of detachable folding shape cast irons, 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; Connect with fire door main body 1 by heat-resisting bolt along 2 under the detachable folding shape cast iron.
The present invention compared with prior art has following beneficial effect: by 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 large, the burnt rate of reductionization, improve UTILIZATION OF VESIDUAL HEAT IN and full coke yield, the less wasting of resources; Reduce simultaneously because of under the upper furnace door along scaling loss, and change the number of times of whole upper furnace door, only the changing under the detachable folding shape cast iron along getting final product of edge under the scaling loss improved Business Economic Benefit and social benefit on the whole.

Fig. 2 is backsight structural representation of the present invention,
Fig. 3 is side-looking structural representation of the present invention,
Fig. 4 is I section enlarged view among Fig. 3.
Embodiment:
A kind of clean type heat reclamation coke furnace upper furnace door, fire door is by forming along 2 under the detachable folding of oven door body 1 and the 3 shape cast iron, and 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; Connect with fire door main body 1 by heat-resisting bolt along 2 under the detachable folding shape cast iron.A kind of clean type heat reclamation coke furnace upper furnace door, with upper furnace door from originally exceeding protecting sheet and being wider than the lower edge of width of charring chamber, change the equally long lower edge of width the same as coking chamber into, and lower edge highly dropped to be parallel to protecting sheet, for oven door sealing lays the foundation, segmental arc and upper protecting sheet contact site mill out half-arc groove on the fire door, cling braided asbestos round packing with binding agent inside, half asbestos twine that protrudes and upper protecting sheet plane contact, firmly contact from original plane, change flexible contact into, utilize the cart pressure of installing fire door, make braided asbestos round packing flatten into the plane and fully contact with the version backplate; Secondly the primary structure design being changed under main body and the 3 detachable cast irons folding shapes along combining, is that better air-proof condition is created in upper and lower fire door contact surface sealing, also is convenient to simultaneously change, keep in repair; Improve simultaneously door lining thermal insulation layer and pouring layer material, reach better heat insulation effect.
Claims (1)
1. clean type heat reclamation coke furnace upper furnace door, comprise that fire door is by oven door body (1) and 3 detachable foldings under the shape cast iron along (2), it is characterized in that: oven door body (1) is provided with segmental arc, segmental arc is provided with half-arc groove (3), half-arc groove is provided with braided asbestos round packing in (3), detachably rolls under the shape cast iron to connect with fire door main body (1) by heat-resisting bolt along (2).
