Abstract
The invention discloses a process for manually mending the furnace wall of a carbonization chamber. The process comprises the following: (1) a step of fixing a heat isolation rack: according to a mending part, the heat isolation rack is manufactured; the surface of the heat isolation rack is coated by a heat isolation blanket; the heat isolation rack is pushed to the part of the furnace wall needing mending in the carbonization chamber; and the top of the heat isolation rack is fixed on a furnace frame; (2) a step of paving the heat isolation blanket; graphite and impurities on the bottom of the furnace are cleaned up; the heat isolation blanket and a passage plate are paved; and the heat isolation blanket is stuck on the furnace wall to be treated mended and the furnace wall on the periphery of the heat isolation rack; (3) a step of constructing the inside of the furnace of the carbonization chamber: after the furnace walls at two sides are stuck with the heat isolation blanket, no naked fire is determined to eject; and the mending construction is carried out; and (4) a step of detaching and mending a melting loss part. The mending process can carry out mending in the carbonization chamber under the environment of high temperature of 1,000 DEG C around, reduce cost, improve the service life of the coke furnace, does not influence production and is a feasible and effective method.
Description
Technical field
The invention belongs to the coking technology field, relate in particular to a kind of manual repair technique of coking chamber wall that is used for coke furnace carbonization chamber.
Background technology
Coke oven construction partly is made up of furnace roof, combustion chamber, coking chamber and flue etc.Temperature is about 1300 degrees centigrade, based on coking in the coking chamber stove.Coking chamber mainly is to deposit coal, in process of coking, tar that produces and graphite are attached on the charing locular wall, accumulation will be touched with the discrepancy of coke pusher for a long time, and the unavoidable error that in the temperature adjustment process, occurs of the quality problems of charing locular wall silica brick own and operative employee, cause the serious melting loss of charing locular wall silica brick.Because the characteristic of silica brick material must be repaired under the environment of about 1000 degrees centigrade of high temperature.The main in the past method that adopts is to the mould material spray repair of the position of silica brick melting loss, and after use for some time, coming off of mould material will similar disrepair phenomenon can occur again, and spray repair is more frequent.If the blowing out overhaul is very expensive not only, also influence is produced.
Summary of the invention
Technical problem to be solved by this invention provides carries out the manual repair technique of coking chamber wall that repair artificial furnace wall under a kind of hot environment, to improve the work-ing life of coking chamber, satisfy the needs of ordinary production.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of manual repair technique of coking chamber wall is characterized in that, comprises the steps:
(1), fixing heat insulation: make heat insulation according to repairing the position, wrap up with heat-insulation blanket on heat insulation surface, pushes eligible for repair position in the coking chamber with heat insulation, and heat insulation top of the trellis is fixed on the stove frame;
(2), shop heat-insulation blanket: clear up furnace bottom graphite, foreign material, spread heat-insulation blanket and walk guidance tape, heat-insulation blanket is attached to waits to repair on furnace wall and the heat insulation frame peripheral furnace wall then;
(3), construction in the stove: wait post heat-insulation blanket on the furnace wall of both sides after, confirm not have the naked light ejection, carry out reparation construction then;
(4), remove the melting loss position, repair.
Beneficial effect of the present invention is as follows: adopt repair technology of the present invention can carry out coking chamber under the environment of about 1000 degrees centigrade of high temperature and repair, not only reduced cost, and the work-ing life of having improved coke oven, do not influence production, be a kind of desirable and effective means.And repair technology of the present invention is practical, according to the situation that occurred coking chamber wall silica brick melting loss in the past, if what occur is slight melting loss, repair with regard to adopting common gunning technology, if bigger serious melting loss occurs, just take the method for landfill, stop the use of this part, so not only influence is produced, and has also wasted the utilization of resource.And adopt this scheme, and neither wasting resource, can reduce cost again, according to statistics, after the repairing, can more than the method that occurred this situation employing landfill in the past and produce 2000 stove left and right sides coke (under normal circumstances, annual coking chamber can be produced about 360 stoves).Be worth considerable, and easy to use.

Embodiment
Further specify the present invention below in conjunction with accompanying drawing and specific embodiment.
Coking chamber wall 1 for melting loss position 2 shown in Figure 1 can adopt following steps to repair:
At first, as shown in Figure 1, the repairing personnel have dressed proximity suit, proximity gloves and face shield, with pushing machine the coking chamber door is removed then, make the bottom according to the size of repairing the position and be heat insulation 4 of inverted " L " type, heat insulation 4 one-tenth vertical shapes are pushed the position that the coking chamber domestic demand is repaired, heat insulation top of the trellis is fixed on the stove frame 5, position to be repaired is enclosed in 90 inverted "L" shaped heat insulation of spending;
Secondly, as shown in Figure 2, cleaning furnace bottom graphite, foreign material are spread heat-insulation blanket 3 and are walked guidance tape, heat-insulation blanket is attached to successively waits to repair on furnace wall and the heat insulation frame peripheral furnace wall 1 then, note preventing the high temperature scald; After posting heat-insulation blanket on the furnace wall of both sides, confirm not have the naked light ejection, construct then.
Remove the melting loss position, repair: at first will repair the position and sever with pneumatic special-purpose brick cutting machine, as shown in Figure 4, the anti-material of melting loss is removed cleaning totally successively along slot, successively repair then, attention can not be fallen into rubbish in the combustion chamber, and the furnace wall that repairing is finished as shown in Figure 5.
Adopt above-mentioned repair technology, improved the work-ing life of coking chamber greatly, reduced production cost, guaranteed the stable smooth operation of producing.
