Description
Technical field
The utility model relates to the assembly in a kind of charring furnace and the pit kiln, relates in particular to a kind ofly to be used for the sealing of the body of wall face of coke oven regenerator heat insulationly, reduces a kind of insulated wall assembly of the loss of its coke oven heat.
Background technology
Each tame iron and steel metallurgy enterprise is extensive use of in its production process and has arrived charring furnace or pit kiln at present; wherein have a kind of regenerator type coke oven; and this regenerator body of wall face has all adopted corresponding heat insulation mode; to protect inner masonry not to be subjected to ectocine; at utmost blocks the coke oven heat and scatter and disappear, and the provision for thermal insulation under the prior art there are following three kinds of forms:
1. the envelope wall that adopts insulating brick to build by laying bricks or stones carries out heat insulation mode, though this kind mode cost is lower, and brick-building art requires lower, and be widely used, but in the process of real world applications, there is variety of problems: because be to build by laying bricks or stones by insulating brick to form entirely, cause between brick and the brick mortar joint many, and bad adhesion between clay chamotte and the insulating brick; And the heat insulation brick wall of this kind at high temperature uses for a long time, and the envelope wall easily produces the crack, thereby causes the outer freezing air of stove to bleed in a large number easily, has influenced the tight performance and the hot working efficiency of coking furnace shaft.And for the repairing that produces fissured envelope wall, generally adopt jointing and smear the mode place under repair of benefit.This repairing method, not only workload is big, and poor effect.
2. adopt the insulation plate mode, the insulation plate sealing means is a kind of improved form of insulating brick masonry sealing means wall, for avoiding fissured generation that insulating brick is built in advance in the cast iron case, carry out complete installation then, be fixed on the positive position of regenerator with jackscrew.General one stride regenerator sealing wall be equipped with two insulation plates (between large furnace stay and the port jamb envelope wall be called stride the envelope wall).Though the type regenerator front sealing means avoided the mortar joint of insulating brick masonry sealing means many, easily produce deficiencies such as crack, it also has the following disadvantages:
(1) during insulation plate seam crossing generation blowby, blowby place is difficult for finding, and is difficult to judge wherein concrete blowby position, brought very big difficulty to maintenance;
(2) the general employing of maintenance is smeared slurry at seam crossing, jointing reaches modes such as breaking asbestos twine, so maintenance capacity is big, and effect is bad;
(3) installation of insulating brick belongs to complete installation, because an insulation plate weighs 30 kilograms, so working strength is bigger when installing;
(4) in use there is expansion in coking furnace shaft, causes fixedly that the jackscrew pressure of insulation plate changes, thereby daily need are followed the tracks of adjusting to it, and it is big therefore to regulate maintenance.
3. adopt the heat insulation mode of laminated pouring.Be specially and adopt fixedly thermal insulation coatings of expanded metal lath,, prolong its bridging time to improve the bridging performance of thermal insulation coatings.Though the heat insulation mode of the positive face seal of the type regenerator avoided equally the mortar joint of insulating brick masonry sealing means many, easily produce deficiencies such as crack, also there is following problems in it:
(1) thermal insulation coatings is a kind of slurry with moisture, smears on the regenerator sealing wall by after the oven dry, and the slurry shrinking percentage is big, and crackle is many, has influenced sealing effectiveness;
(2) relative other lagging material of the thermal conductivity of thermal insulation coatings slurry still is higher, and effect of heat insulation is not desirable;
(3) density of lagging material and clay chamotte and refractory brick is inequality, and thermal expansivity is also different, and throwing off easily under body of heater after-expansion and hot environment becomes two portions, greatly reduces the heat-insulating and sealing effect.
Application number: 200520042020.1, the applying date: on 05 31st, 2005 Chinese patent, a kind of coke oven regenerator sealing heat-proof device, it is installed on the outside surface of refractory brick in coke oven regenerator front, and the sealing heat-proof device comprises from inside to outside clay chamotte, internal layer thermal insulation coatings, expanded metal lath, the outer thermal insulation coatings of cast successively; This expanded metal lath comprises by spot welding mode fixedly connected waffle slab and angle iron frame, also is provided with several standing bolts on angle iron frame.
This patent is by improving the sealing property and the effect of heat insulation at the positive position of coke oven regenerator, can improve the coke oven end temperature, reduce the coking thermal losses, improve the coke quality at burner position, but it has adopted " waffle slab that the spot welding mode is fixedly connected and angle iron frame ", and the mode of connection that increases temperature glue with the warming plate of employing dislocation type of the present utility model has significantly different.
In sum, now need a kind of can avoid mortar joint many, easily produce the crack, the problem of heat insulation effect difference, and need to improve the tightness of coke oven regenerator position body of heater reduces the coke oven thermosteresis, and easily construction, easy-maintaining.
