Description
Technical field
The utility model relates to the service technique of coke oven horizontal flue, more particularly, relates to a kind of coke oven horizontal flue apparatus for examination and repair, and this apparatus for examination and repair can help the inspection and the repairing work of coke oven horizontal flue.
Background technology
The coke oven horizontal flue is the horizontal gas flow passage that is in the coking furnace shaft foot, a part that belongs to coke oven regenerator, horizontal flue connects the coke oven regenerator bottom on all, be provided with exhaust gas disc between adjacent two horizontal flues, the horizontal flue of every exhaust gas disc both sides (coal gas side and air side) is connected, and as one group, when upstream, coal gas sidles mixed gas, and air sidles air, all walks combustion exhaust when downdraft.Several horizontal flues are separated by with master, single partition wall respectively all along the coke oven arranged transversely, and the part coke oven also has center partition, and single partition wall two sidles air-flow in the same way, and main partition wall two sidles incorgruous air-flow.But along with the coke oven continuous increase in furnace life, each position of body of heater can inevitably produce damage phenomenons such as crack, and horizontal flue is no exception.In a single day the horizontal flue main wall produces the crack, and its both sides certainly lead to the blowby phenomenon because of the existence of incorgruous air-flow differential, and promptly gas is scurried into the horizontal flue of downdraft from the horizontal flue of upstream.Because the air side of horizontal flue and coal gas side are alternately, main partition wall blowby causes the bleed air side of downdraft of mixed gas easily, the air coal gas side of downdraft of then bleeding, thus cause spent air temperture to reduce, chimney suction reduces, and has caused the meaningless increase of gas consumption.Therefore, must be to checking in the horizontal flue and repairing.See also shown in Figure 1, coke oven horizontal flue 10 has four with the extraneous opening that communicates, its split shed 1 is positioned at two forks, bore is 160 * 190mm, opening 2 is positioned at exhaust gas disc 11 loam cake places, bore is 200 * 200mm, opening 3 is positioned at exhaust gas disc 11 side cover places, owing in the middle of the exhaust gas disc 11 the top bar is arranged, cause its effective aperture to have only 190 * 400mm, opening 4 is the downward modulation mouth, internal diameter is 15mm, because these four opening bores are too less, and the interior dimensions of horizontal flue 10 is very big, is 8000 * 248 * 700mm, big size disparity like this, making does not also have more suitable service kit at present, can either enter horizontal flue 10 by opening, can overhaul comprehensively and effectively in horizontal flue 10 again.
At present, can only be by the exhaust gas constituents at exhaust gas disc 11 places be analyzed, and by the partition wall situation that analytical results comes indirect determined level flue 10, if carbon monoxide content is higher in the waste gas, then is judged to be partition wall and has blowby.But there is not suitable checking tool, thereby can't judge the concrete position of blowby, can only adopt the whitewashing bar to extend in the horizontal flue 10 from the downward modulation mouth, by metope is whitewashed comprehensively, spray stifled contingent local cracks, so repairing work very blindly, workload is big, but repair efficiency is very poor, and a horizontal flue 10 is implemented repeatedly whitewashing sometimes, also is difficult to solve the problem of partition wall local cracks.
The utility model content
Above-mentionedly do not have suitable service kit effectively overhauled and can't check out blowby to horizontal flue concrete position, blindly repair and cause that workload is big, the shortcoming of weak effect at what exist in the prior art, the purpose of this utility model provides a kind of coke oven horizontal flue apparatus for examination and repair, and this apparatus for examination and repair can enter in the coke oven horizontal flue and to horizontal flue and carry out accurately, effectively checks and repair.
