Abstract
The invention belongs to the field of gas pipeline safety protection and particularly provides an on-line plugging method for a gas pipeline through rubber and a steel wire. According to the on-line plugging method for the gas pipeline through the rubber and the steel wire, a leak portion of the gas pipeline is found through an ultrasonic detector, the rubber with the size slightly larger than the leak portion of the gas pipeline is taken and tightly attached to the leak portion of the gas pipeline, and then the rubber is bound to the pipeline through the steel wire. The on-line plugging method for the gas pipeline through the rubber and the steel wire is applied to the running process of a blast furnace system and is simple, easy to implement and capable of preventing leakage of a large amount of gas; when the blast furnace system blows out for overhaul, the leak portion of the pipeline can be cut off, and then the pipeline can be repaired again.
Description
Technical field
The invention belongs to gas pipe line safety protection field, specifically the online blocking method of a kind of gas pipe line rubber steel wire.
Background technique
Coal gas spot blast furnace, converter, coke oven have larger distance apart from coal-gas recovering ground, blast furnace gas excess pressure power generating machine and gas fired boiler, and gas pipeline is arranged in the both sides of blast furnace region, coke oven region, company's visit passage and major roads substantially.In long-time running, gas pipe line is because of the wearing and tearing of weld defect, dust-laden coal gas, and since particularly blast furnace dry method dust puts into operation, pipeline occurs gas leakage phenomenon because of acid etching.This not only threaten pedestrians personal safety, pollute surrounding environment, affect gas to generate electricity amount, especially in the winter time, also may affect surrounding area resident heat.
Summary of the invention
Technical problem to be solved by this invention is: how to solve gas pipe line because of reasons such as wearing and tearing, corrosion, make gas pipe line part occur the defects such as cavity, and cavity around in larger area gas pipe line tube wall effective thickness too little, make to weld the defects such as easy generation is burnt, distortion and cannot use the problem of welding method leak stopping.
The technical solution adopted in the present invention is: the online blocking method of gas pipe line rubber steel wire, search out gas pipeline leakage position by ultrasonic detector, get the rubber that is slightly larger than gas pipeline leakage position and be close to gas pipeline leakage position, rubber is bundled on pipeline with wire rope.
The invention has the beneficial effects as follows: the present invention is the online blocking method of a kind of gas pipe line rubber steel wire in blast furnace system running, and the method is simple, easily operation, can prevent a large amount of leakages of coal gas, in the time of blast furnace system shutdown maintenance, this segment pipe can be cut off, re-start reparation.
Brief description of the drawings
Fig. 1 is structural representation plan view of the present invention and left view;
Wherein, 1, gas pipeline leakage position, 2, rubber, 3, steel wire.
Embodiment
The problem of, power consumption consuming time for stop system gas treatment pipe leakage, complicated operation, threat life safety and coal gas diffusion befouling environment, to because of reasons such as wearing and tearing, corrosion, make gas pipe line part occur that tube wall effective thickness is too little or occurred the situation in larger area cavity, adopting the preventative online leak stopping of rubber steel wire or online leak stopping.
Seam leakage blinding utilizes the weldability of metal, aspect the leak stopping of the many gas pipe lines of our factory, obtaining good effect, but for gas pipe line because of reasons such as wearing and tearing, corrosion, make gas pipe line part occur the defects such as cavity, and gas pipe line tube wall effective thickness is too little within the scope of empty larger area around, make to weld the defects such as easy generation is burnt, distortion and cannot use welding method leak stopping, for this defect, can adopt the fastening method of pad rubber steel wire to solve temporarily.
As shown in Figure 1, this method is utilized the soft character of rubber, makes it be close to gas pipeline leakage position, then with wire rope, rubber is bundled on pipeline.The size dimension of rubber, the quantity of wire rope can determine according to leakage position area.This method is simple, and easily operation, can prevent a large amount of leakages of coal gas, in the time of blast furnace system shutdown maintenance, this segment pipe can be cut off, and re-starts reparation.
Implement before leak stopping, safety climbing ladder must be set up in leak stopping scene.In the time possessing following condition, can carry out leak stopping: scene must have 2 people to guard; Welding personnel must wear respirator; Protection station professional workforce must await orders at the scene.
Since Stainless-steel Jiont Stock Company of Taiyuan Iron&Steel Complex adopts the leak stopping of rubber steel wire to gas pipe line, avoid blast furnace fault damping down repeatedly, reducing main production unit fault stops transport repeatedly, reducing supplement production factory and our factory's gas fittings fault stops transport more than ten times, produce to carry producing to create imitating for corporate security and brought into play great role, produced larger economic benefit, environmental benefit, social benefit.
