Description
Technical field
The present invention relates to the maintenance technology of a kind of large capacity coke oven, specifically, relate to a kind of large capacity coke oven
Key equipment integral replacing method derived by raw coke oven gas.
Background technology
The key equipment order from bottom to top that derives of raw coke oven gas is: tedge base, tedge, bridge tube
And water seal seat, the raw coke oven gas in coke oven sequentially passes through tedge base, tedge, bridge tube and water seal seat,
Water seal seat is connected with coke-stove gas conveyance conduit.After coke oven is gone into operation, production has continuous, continual
Feature.Along with the coke oven life-span steps into middle and late stage, because of design or original construction quality problem, tedge or on
Phenomenon is snapped owing to serious scaling loss there will be in the local of riser base, in causing tedge and tedge base
The raw coke oven gas leakage of conveying, causes environmental pollution；Or cause bridge tube and water seal seat entirety imbalance to be inclined
Tiltedly, so cause tedge water seal segregation, water seal height not, water seal weak effect, cause raw coke oven gas from
Water seal seat is excessive.It addition, often occur that water seal water tilts to burner position, cause jamb brick well damage,
Tie rod corrodes and then makes burner position tie rod hook that string leakage occur.
Comprehensive factors above analysis, coke oven produces the regular period and is accomplished by tedge or tedge base
It is replaced.It is individually replaced any equipment and is required for first taking away the equipment on its top, operation is complicated,
Replacing requires time for longer, at least needs 4-5 hour, has typically been difficult within the coke oven normal service phase
Replacing task.
Summary of the invention
It is whole that technical problem solved by the invention is to provide a kind of large capacity coke oven raw coke oven gas derivation key equipment
Body replacing options so that replacing more saves time, operability is higher.
Technical scheme is as follows:

Molectron is installed to derive the position of key equipment, is mounted and connected the auxiliary device of molectron.
Further, the step that derivation key equipment is combined into molectron includes:
Make upper semisection and the lower semisection of tedge to be replaced, at the two ends welded flange of upper semisection,
The two ends welded flange of lower semisection；
Resistance to by carrying out as requested inside tedge base to be replaced, upper semisection, lower semisection, bridge tube building
Firebrick；
After building refractory brick, upper semisection and lower semisection are passed through flange and bolt assembly and connection, and in method
Blue junction flange packing seal, forms tedge to be replaced；
With bolt, tedge base to be replaced, tedge, bridge tube are connected, the flange outside tedge
Connect flange and the flange of bridge tube of tedge base respectively, water seal seat is arranged on bridge tube, and uses stone
Cotton cord seals, and is combined into molectron.
Further, the step utilizing molectron replacing to take off derivation key equipment includes:
Calculate the coke pushing time, clear up to be changed bell and spigot, push the refractory material of tedge base position aside, and
Disconnect water in be changed ammonia and water seal；
Sling and derive key equipment and remove；
Cleaning tedge base position refractory material, is newly built tedge base brick, and it is tight to be in the milk by code；
Sling molectron, and have bad luck to be changed position, install as requested and put in place；
Confirm that installation site and relative dimensions are errorless, tight tedge base and bell and spigot, connect bridge tube ammonia
Water sprays and water in water seal.
Further, also include: after all installing tightly, site clearing rubbish, make that newly changes to lead
Go out key equipment to recover to production status.
Compared with prior art, the technology of the present invention effect includes:
1, utilizing the present invention, large capacity coke oven carries out integral replacing raw coke oven gas under production status derives key
Equipment, i.e. changes water seal seat, bridge tube, tedge and tedge base so that replacing more saves time, can grasp
The property made is higher.
2, the present invention uses integral replacing method to change in large capacity coke oven by tedge, tedge base, bridge
Pipe and the molectron of water seal seat composition, have the features such as the used time is short, intensity is low, by major part furnace roof high temperature
The regional work time is transferred in preliminary preparation, it is ensured that more changing jobs can be in the shorter maintenance of coke oven
Complete in time, general at most need 2.5 hours, thus neither affect coke oven and normally produce and turn avoid
In furnace roof high-temperature area long working.
3, remarkable in economical benefits of the present invention, and the potential safety hazard in production process can be eliminated.
The equipment loss that smoldering by every coal oven dithio-gas equipment leading out catches fire causes is with gas leak benefit about
350000 yuan/year, the environmental pollution caused of catching fire but effective solution coal oven dithio-gas equipment leading out is smoldered, carry
Rising coking technique management level, the social benefit highlighted is bigger, also eliminates raw coke oven gas equipment leading out simultaneously
The potential safety hazard that breakage brings.
Detailed description of the invention
Below with reference to preferred embodiment, contrast technical solution of the present invention elaborates.
Do not affect coke oven production to save the operating time, substantial amounts of work is all placed on early-stage preparations as far as possible
In work, carry out raw coke oven gas derivation key equipment integral replacing and large capacity coke oven hot repair is safeguarded have extremely
Important meaning.
Operation in order to overcome coke oven coke oven uprising tube or tedge base to change is complicated, affect the tired of coke oven production
Difficult.The present invention replaces with the method for riser or tedge base and is made that new elaboration large capacity coke oven,
Propose integral replacing tedge base, tedge, bridge tube and water seal seat, using above-mentioned parts as combination
Part carrys out integral replacing, and early-stage preparations and operating procedure have been carried out system specifications and optimization.Integral replacing is
Tedge, tedge base, bridge tube and water seal seat are measured in advance and be assembled into molectron, when changing

Check the auxiliary device of molectron, including: to be changed valve body turnover panel, low pressure ammonia cock, high pressure
Ball valve and water seal water supply valve, airduct, coal car ceiling mounted arm or crane tool put in place.Coordinate coke oven scheduled overhaul
Time, make to be changed number after 2/3 coking time, and replacing construction to be ensured is at more than 2h.Coordinate to make
Industry personnel, mainly have frame work, plumber, pneumoelectric welder, bricklayer and coal tar car driver etc..
Step 1 and step 2 are the preliminary preparations of replacement operation.
Step 3: operation suspender entirety takes off derivation key equipment, utilizes molectron to change and takes off derivation pass
Button apparatus, is installed to molectron derive the position of key equipment, is mounted and connected the attached of molectron and sets
Standby.
Step 31: calculate the coke pushing time；
Preferably within first about 4 hours, start to change molectron in be changed coke pushing.
Step 32: clear up to be changed bell and spigot, pushs the refractory material of tedge base position aside, and disconnection is treated
Water on the number of changing ammonia and water seal；
Step 32: derivation key equipment of slinging (tedge base, tedge, bridge tube and water seal seat combination
Part), and remove；
Paying special attention to, when hoisting facilities is installed, coal car is crossed in sling height to be considered molectron to be met bottom
Track, in order to have bad luck molectron time-consuming；
Step 33: cleaning tedge base position refractory material, is newly built tedge base brick by code, and
Grouting is tight；
Step 33: molectron of slinging, and have bad luck to be changed position, install as requested and put in place；
Step 34: confirm that installation site and relative dimensions are errorless, tight tedge base and bell and spigot, even
