Abstract
The invention relates to a novel heat recovery coke oven riser bridge pipe lining and a local repairing method thereof, belonging to the field of a heat recovery coke oven and solving the problems that an iron plate at the damaged part is cut off, and directly repaired by a castable, thus the structural strength is low and the lasting time is short. The novel heat recovery coke oven riser bridge pipe lining is characterized in that a steel reinforcement network is arranged in the castable. The local repairing method for burnt castable comprises the steps of: completely closing suction regulating bricks at the damaged side through a fire regulation worker, cutting off the burnt part on the side wall of the riser bridge pipe through gas cutting equipment, cleaning the residual burnt castable, additionally installing the reinforcement network in the castable-poured lining, placing the reinforcement network at the position which is used for constructing the castable, constructing the damaged part with the castable so that the reinforcement network is positioned in the middle of the castable, and leaving a 25mm gap between the outer side of the castable and the inner side of the side wall; constructing the castable into a wall along with the reinforcement network, leveling a wall surface, paving a heat-insulation plate at the gap, welding the cut iron plate back to the original position, and coating asphalt paint. According to the novel heat recovery coke oven riser bridge pipe lining and the local repairing method thereof, the strength of the castable is greatly enhanced, and the service life of the repaired riser bridge pipe is prolonged.
Description
Technical field
The invention belongs to heat recovery coke oven technical field, be specifically related to New Type Coke Oven with Heat Recovery rising bridge tube liner and sectional repair method thereof.
Background technology
Heat recovery coke oven is negative-pressure operation in process of production, high-temp waste gas after coke oven internal combustion imports rising bridge tube by the rising quirk on main wall, after be aggregated into effuser and enter waste heat boiler and transform generating, because rising bridge tube is inner, build by laying bricks or stones for mould material, through long actual motion, there is in varying degrees the phenomenons such as mould material comes off, appearance scaling loss in rising bridge tube both sides, cause rising bridge tube localized hyperthermia, the obstruction of rising quirk, coke oven machine, coke side temperature and suction uneven, the validity of UTILIZATION OF VESIDUAL HEAT IN is had a negative impact simultaneously; Prior art, takes in the situation that coke oven does not stop production, and damaged location appearance iron plate is sliced off, and directly uses mould material reparation, and structural strength is lower, and the time length is shorter.
Summary of the invention
The present invention solves the problem that prior art exists, and New Type Coke Oven with Heat Recovery rising bridge tube liner and sectional repair method thereof are provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be:
New Type Coke Oven with Heat Recovery rising bridge tube liner, comprises mould material, is characterized in: in described mould material, be provided with reinforcing mat.
Heat recovery coke oven rising bridge tube method for repairing inner lining, is characterized in: its concrete steps comprise:
The first step will be damaged the suction adjusting brick Close All of side;
Second step slices off iron plate corresponding to rising bridge tube sidewall mould material scaling loss position with gas cutting equipment;
The 3rd step is removed the residual bad mould material of watering;
In the liner that the 4th step is built by laying bricks or stones in mould material, install reinforcing mat additional: reinforcing mat is placed in to the position of preparing to build by laying bricks or stones mould material, makes reinforcing bar wire side and rising bridge tube parallel sidewalls and apart from rising bridge tube sidewall certain distance;
The 5th step is built damaged location by laying bricks or stones by mould material, makes reinforcing mat be positioned at mould material middle part, the gap of reserved 25mm between mould material outside and inside sidewalls; Along reinforcing mat, build into mould material by laying bricks or stones wall, floating metope;
The 6th step is put after 60 minutes until the floating metope of the 5th step is cool, and with mixing with high temperature resistant cement containing the mould material of 12% moisture content, the inner grouting of backward mould material wall cracking is also floating;
The 7th step is at the gap location paving thermal baffle of the reserved 25mm of the 5th step;
The 8th step welds go back to by the iron plate of cutting off the position that second step gas cutting equipment slices off iron plate;
The 9th step pitching paint on the iron plate welding.
The present invention compared with prior art, has following beneficial effect:
The present invention adopts the method that installs reinforcing mat in mould material additional, and the intensity of mould material is significantly improved, and makes the rising bridge tube life after maintenance.
