Abstract
The invention discloses a method for repairing dry quenching coke bypass flow medium plug leakage, which comprises the following steps: the department of leaking of bolt root is enclosed the fender with setting up one in bypass flow, enclose the fender around the well bolt sets up and is higher than the protective shroud of well bolt flange cover, then the protective shroud with enclose between the fender the pouring material, keep level with well bolt iron box roof at least to the pouring material, thereby treat that the pouring material solidifies back pouring material and well bolt iron box roof combine to carry out the shutoff with the pouring material with the leakage point. The invention aims to provide a method for repairing leakage of a bypass flow medium bolt of dry quenching coke, which is used for repairing a leakage point of the bypass flow medium bolt by adopting a special method aiming at the phenomena of untight sealing, burning out, leakage and the like of the bypass flow medium bolt of the dry quenching coke, and avoiding the influence on normal production of the dry quenching coke due to the fact that the production of the bypass flow medium bolt is stopped for replacement.
Description
Technical Field
The invention relates to the field of coke dry quenching in the coking industry, in particular to a method for repairing coke dry quenching bypass flow medium plug leakage.
Background
At present, steel-coated coal coking division companies have 5 sets of dry quenching devices, a new area has 2 sets of dry quenching devices, and the processing capacity is 200 t/h; 3 sets of dry quenching devices are arranged in the old area, the processing capacity is 125t/h, and each set of dry quenching devices in the new area is respectively provided with 16 bypass flow and air introduction medium plugs; each set of dry quenching coke in the old area is respectively provided with 24 bypass flow and air introduction.
And when the inlet valve is in an open state, the introduced air enters the dry quenching tank from two sides of the annular flue through the bypass flow and the air introduction middle bolt and is converged with the circulating gas. O introduced into the air2With H in the recycle gas2And CO and coke powder particles are subjected to combustion reaction, so that the aim of reducing the concentration of combustible components in the circulating gas can be fulfilled.
As the gas composition operation of leading-in air into the regulating circulation system is required every day in order to ensure the qualification of the circulating gas composition of the system in the normal production of dry quenching, the bypass flow middle bolt of the dry quenching is in a high-temperature state for a long time, the phenomena of untight sealing, burning out, leakage and the like of the bypass flow middle bolt can occur, the phenomena of the untight sealing, the burning out, the leakage and the like of the bypass flow middle bolt generally occur at the root part of the bypass flow middle bolt, the normal air leading-in operation is influenced, a large amount of air coke powder and circulating gas can be sprayed out due to the untight sealing, the burning out and the leakage, the surrounding2Toxic and harmful components such as CO, the pollution to the surrounding environment, the potential safety hazard and the like, and the device forms a part for operating and inspecting personnel in the areaAnd (4) harming. Meanwhile, the leakage of the middle plug can suck a large amount of air, and the burning loss of the coke dry quenching is increased. The coke dry quenching in the new area of our factory repairs 8 by-pass flow medium plugs on the site according to the method, and the using effect is very good at present.
Disclosure of Invention
The invention aims to provide a method for repairing leakage of a bypass flow medium bolt of dry quenching coke, which is used for repairing a leakage point of the bypass flow medium bolt by adopting a special method aiming at the phenomena of untight sealing, burning out, leakage and the like of the bypass flow medium bolt of the dry quenching coke, and avoiding the influence on normal production of the dry quenching coke due to the fact that the production of the bypass flow medium bolt is stopped for replacement.
In order to solve the technical problems, the invention adopts the following technical scheme:
the invention discloses a method for repairing coke dry quenching bypass flow medium plug leakage, which comprises the following steps:
the department of leaking of bolt root is enclosed the fender with setting up one in bypass flow, enclose the fender around the well bolt sets up and is higher than the protective shroud of well bolt flange cover, then the protective shroud with enclose between the fender the pouring material, keep level with well bolt iron box roof at least to the pouring material, thereby treat that the pouring material solidifies back pouring material and well bolt iron box roof combine to carry out the shutoff with the pouring material with the leakage point.
Further, the enclosure is an iron ring.
Further, the enclosure is an iron ring made of an iron pipe.
Further, the clearance between the enclosure and the retainer is not less than 3 cm.
Further, the clearance between the enclosure and the retainer is 5 cm.
Further, the castable covers the upper surface of the top plate of the middle bolt iron box.
Compared with the prior art, the invention has the beneficial technical effects that:
the method for repairing the plug leakage in the bypass flow of the dry quenching has the advantages of being simple in manufacturing operation, convenient to use, good in using effect and the like, and having unique innovativeness. The method solves the problems that the bypass flow middle bolt is not tightly sealed, burnt out and leaked and needs to be stopped for replacement, can be repaired during normal production of the dry quenching coke, does not influence normal production, does not influence adjustment after the repaired bypass flow middle bolt, and has very good use effect.
The invention adopts a special method to repair the bypass flow middle bolt leakage point, avoids the influence on the normal production of the coke dry quenching due to the fact that the bypass flow middle bolt leakage needs to be stopped for replacement, and simultaneously thoroughly eliminates the factors that the environment is polluted by the coke powder overflow caused by the on-site burning out leakage of the bypass flow middle bolt and the unsafe harm factors brought to the operators nearby the area by the toxic gas leakage.
The invention has convenient and rapid operation, solves the problem of plug leakage in bypass flow, and avoids the potential safety hazard of peripheral environmental pollution and gas leakage caused by leakage. The bypass flow middle bolt is protected from being burnt due to leakage; the coke dry quenching production stop is avoided, the normal coke dry quenching production is ensured, the coke dry quenching maintenance time is saved, and the effective coke dry quenching operation time is prolonged.
Detailed Description
A method for repairing leakage of a coke dry quenching bypass flow medium bolt is characterized in that an iron ring is manufactured at a leakage position of the root of the bypass flow medium bolt by using an iron pipe, the iron ring is required to be larger than the medium bolt by one circle (the gap is 3-5cm) and is higher than a guard ring of a flange cover of the medium bolt, then pouring materials are poured into the iron ring, after the pouring materials are solidified, the pouring materials are combined with a top plate of a medium bolt iron box, the leakage point is blocked by the pouring materials, a sealing effect is achieved, meanwhile, the adjustment of a switch of the medium bolt is not influenced, and the problem of root leakage of the medium bolt is effectively solved.
The invention has simple manufacture and operation, convenient use and good use effect. The method solves the problems that the bypass flow middle bolt is not tightly sealed, burnt out and leaked and needs to be stopped for replacement, can be repaired during normal production of the dry quenching coke, does not influence normal production, does not influence adjustment after the repaired bypass flow middle bolt, and has very good use effect.
