Description
Technical field
The present invention relates to a kind of can in advance brush the material for being mixed with polymeric absorbent to store or transport organic liquid
The normal pressure metal device surface of harmful influence, and when harmful influence leaks, can automatic plugging organic liquid harmful influence leakage
Technical solution.
Background technique
Due to the swift and violent growth of China's economy, chemical industry is fast-developing, and type, the quantity of hazardous chemical constantly increase
Add.Hazardous chemical is in production, transport and uses link, because a variety of causes is likely to result in the accident of harmful influence leakage.By
High in leakage accident disposition difficulty, accident may develop the disaster big for harmfulness such as fire, explosions, and certain dangerization at any time
The leakage of product can cause ecological environment greatly to destroy.In recent years, the harmful influence leakage that frequently occurs, fire, explosion accident, make
At heavy casualties, huge economic loss and serious ecological environment destruction.
In dangerous chemical leakage accident rapid rescue and emergency disposal field, leak stopping is a very the key link.
Leak for harmful influence, common leakage stopping technology has: plug wedge leakage stopping technology, ties up leakage stopping technology, coheres fastening-type leakage stopping technology
It is leakage stopping technology, freezing leakage stopping technology, magnetic pressure leak blockage technology, agent injecting type Live leaking-stopping technology, button-type leakage stopping technology in expansion, negative
Press absorption type leakage stopping technology etc..
In recent years, harmful influence leaks novel quick blocking technology fast development, such as " instant quick blocking technology with pressure ", adopts
With new type explosion proof sealing device and unique injection process, can it is not parking, do not influence production in the case where, drawn without scene
Figure is not necessarily to fixture, and the achievable emergency plugging operations to general leakage point in the 30min after leakage occurs solve tradition
The problem that the insoluble privileged sites of blocking technology block.However, increasing at any time since the security risk of leakage accident has
The characteristics of growing and increasing, such as with the growth of leak time, leakage hole is possible to increasing, and the harmful influence of leakage is increasingly
It is more, and the risk that the second accidents such as fire, explosion occur is increasing.Therefore, there is no need to human intervention can be in a short time
The technology of automatic plugging harmful influence leakage, which becomes, to be badly in need of.Hazardous chemical once leaks and will be possible to cause biggish disaster thing
Therefore therefore, for different medium different application place research and development do not have to human intervention can automatic plugging leakage Self-plugging skill
Art can greatly reduce the generation of disaster accident, and the harm of accident is preferably minimized.
Harmful influence is mostly the fluid of gas, liquid in chemical industry, when leak occur when, it will it is caused pressure, dense
The mutation of the parameters such as degree, flow, if in addition, fire incident occurs for harmful influence device or pipeline, temperature can also become
Change.By investigation, has the self-styled plugging technique of some harmful influences, these technologies are usually to utilize pressure, concentration, flow, temperature etc.
The variation of parameter plays the role of Self-plugging by way of mechanical or solenoid valve.
These plugging devices mostly use active design, such as solenoid valve, cause reliability in plugging device use process not high,
Also, this kind of automatic plugging apparatus is arranged on pipeline more, is not easy to be arranged in the surface similar to storage tank or harmful influence tank car, no
The crack on energy automatic plugging harmful influence storage and transportation apparatus surface or small hole.Currently, being capable of automatic plugging organic liquid harmful influence
The technology of storage and transportation apparatus surface crack or small hole, disposition organic liquid harmful influence leakage is rarely reported.
Summary of the invention
In view of the situation of the prior art, in order to make up existing automatic plugging apparatus in terms of power supply design and use scope
Deficiency, and the situation that leaks for some reason of disposition organic liquid harmful influence normal pressure storage and transportation apparatus surface automatically, this hair
In bright, propose a kind of can in advance brush the material for being mixed with polymeric absorbent and storing or transporting organic liquid harmful influence
Normal pressure metal device surface, and organic liquid harmful influence storage and transportation apparatus is blocked by self inflation when harmful influence leaks and is split
The technology of seam or small hole, i.e., it is a kind of can automatic plugging organic liquid harmful influence leakage technical solution, this programme is a kind of
The material for being mixed with polymeric absorbent is brushed in advance or roller coating is in the constant pressure tank body, pipeline, appearance for filling organic liquid harmful influence
The metal surfaces such as device, when harmful influence metal device is because of collision, reasons cause metal the is presented crack such as burn into is poorly sealed or micro-
When small holes (D≤3mm) liquid chemicals leak, crack or micro- can be then blocked by absorption organic liquid self inflation
Small holes, to dispose harmful influence leakage.
