Description
Technical field
The invention belongs to advanced environmental protection industry, it is related to water pollution caused by the product pipeline leakage by damage from third-party
The technical field with reparation is administered in prevention and treatment, soil and place etc., and in particular, to a kind of product pipeline by damage from third-party
Leak the drainage device of emergency disposal.
Background technique
In recent years, with rapid economic development, energy demand is continuously increased.In oil extraction, transport and refining process,
With being continuously increased for product pipeline Construction and operation mileage, exposed product pipeline increases by the probability of damage from third-party, overflows
The probability that oily pollution event occurs increased.Oil spilling cannot get quick recycling disposal, will seriously endanger for the survival of mankind
Ecological environment, the improvement such as water prevention and cure of pollution, soil and place and reparation can be brought it is a series of seriously affect, can also be to being speedily carried out rescue work
Personnel, which march into the arena, brings security risk.
But if leakage occurs suddenly and destroys for the product pipeline runed, and it is difficult the decompression of horse back stopping transportation, Wu Fa
It takes urgent measure in short time and implements permanently to repair, this is resulted in since exposed product pipeline leakage to the oil product
The gap that pipe leakage point is permanently repaired, the oil product near exposed product pipeline leakage point endanger possibility sharply on
It rises.During long-term pipeline contingency management, more careful disposition experience and method are lacked to leakage Oil Recovery.
In addition, processed oil pipeline is different from crude oil pipeline, not only its operating pressure is big, and due to the flowing of product oil
Property, volatility, inflammability and explosion hazard be above crude oil, so once pipeline leakage accident occurs, harmfulness and risk
Greatly, leakage accident occur short time in if without effectively control with leak stopping means, product oil a lot of leakage and make
A possibility that occurring at secondary disasters such as on fire, explosion and environmental pollutions is very big.But because of the particularity of product oil, after leakage
Control and leakage stopping technology and the damage repair technology of Technique of Crude Oil Transport Pipeline Leak are very different, and cannot directly carry out drainage closure, must at
The leakage of product oil first controls to be blocked again, and effectively and safely can control leakage is the primary and crucial of repairing, wherein needing certainly
Reliable drainage device.
Summary of the invention
To solve the above problems, the present invention provides a kind of product pipeline leakage emergency disposals by damage from third-party
Drainage device.The drainage device integral strength height, stable structure, sealing and drainage effect are good, can safely and effectively to by
The product pipeline leakage of damage from third-party carries out emergency disposal, guarantees ambient enviroment and disposal personnel safety.The invention belongs to elder generations
Into environmental protection industry, can be realized to by damage from third-party product pipeline leakage caused by water pollution prevented and treated, soil and
Place etc. is administered and is repaired, oil spill is eliminated and the technical effect of prevention and control, in time, effectively, reliably, safely guarantees ecological ring
