Abstract

The invention relates to a leakage self-saving container for storing a dangerous chemical, which comprises a first container used for storing the dangerous chemical; and a second container which is fixedly arranged in the first container, filled with a substantially harmless liquefied gas and provided with a controllable opening to the outside. When the dangerous chemical is leaked or threatened by a high temperature caused by an accident, the temperature in the first container can be reduced by releasing the liquefied gas in the second container, so that the pressure in the first container is reduced and leakage or explosion caused by over pressure is avoided; or the viscosity of the dangerous chemical is increased to slow the leaking speed of a leakage to win more precious time for effective rescue.

Description

A kind of leakage self-saving container that is used for storing dangerous chemical
Technical field
The present invention relates to a kind of container that is used for storing dangerous chemical, particularly a kind of leakage self-saving container that is used for storing dangerous chemical.
Background technology
Commercial production and people's lives be unable to do without chemical, are dangerous chemicals and quite most of chemical is arranged, and have again wherein very that major part is flowable, comprise gas and liquid, especially low-boiling point liquid.In dangerous chemical production, storage, transportation and use, that idol has is aging because of container, leakage problem takes place for high temperature and accident, brings harm to environment, even causes catastrophic effect.In time and actv. is saved oneself, will win the more quality time for rescue, thus for alleviate harm, averting a calamity property consequence provides bigger possibility.
Summary of the invention
When flowable dangerous chemical took place to leak, the pressure that how to reduce reservoir vessel was the reduction leakage rate with the viscosity that increases dangerous material, reduces the leakage pollution total amount, reduces the key of rescuing difficulty, winning more rescue times.
The present invention relates to a kind of leakage self-saving container that is used for storing dangerous chemical, it comprises:
First container is used for storing dangerous chemical;
Second container is installed and is fixed in described first internal tank, is loaded with harmless substantially liquefied gas in it, and has the opening that controllably opens at external environment.
When in case leakage takes place or is subjected to high temperature to threaten because of accident in the dangerous chemical in described first container, can reduce temperature in described first container by discharging liquefied gas in second container of the present invention, thereby reduce the pressure in first container, avoid leaking or blast because of superpressure causes, perhaps when leaking, pass through to increase the viscosity of dangerous chemical wherein, reach the purpose that reduces leakage rate, for valuable time is striven in more effective rescue.
That leakage self-saving container of the present invention can be used for storing is inflammable, explosive, poisonous, the dangerous chemical of burn into radiation, chemical pollution, and especially can be used for storing dangerous more dangerous chemicals such as gas and liquid, especially low-boiling point liquid.Described dangerous chemical includes but not limited to: POCl3, and gasoline, bromine, liquefied ammonia, liquid chlorine, liquid hydrogen sulfide, hydrocyanic acid, methyl isocyanate, epoxyethane, natural fuels, autogas, alcohol, chloroform, or the like.
Described first container that is used for storing dangerous chemical can be selected according to the character of stored chemical, and can use this area routine to be used for the various containers of storing dangerous chemical.Leakage self-saving container of the present invention can be an autonomous container, also can be the container of all vehicle loads.
In described first container, second container is installed.Be loaded with harmless substantially liquefied gas in described second container.At cause danger for some reason chemical leakage or when being subjected to high temperature and threatening of first container,, emit harmless substantially liquefied gas with gaseous form by opening the emptying valve on second container.The release of described liquefied gas can absorb the i.e. heat in first container of surrounding environment, reduce vessel temp, thereby reduce the pressure in first container, avoid leaking or blast because of superpressure causes, perhaps when leaking, pass through to improve the viscosity of dangerous chemical, and the leakage rate of reduction dangerous article, for rescue gains time.
Described second container can be fixed in described first container by well known to a person skilled in the art any way.The relative position of described second container and described first container is preferably the center that described first container is approached at the center of described second container, and described second container and described first container be direct contact not, make second container main with the first internal tank generation interchange of heat, and wall and the external environment generation interchange of heat by first container not.
Liquefied gas in second container can be selected from any critical temperature more than normal temperature, and to environment and the harmless substantially gas of the person.Described liquefied gas is a gas at normal temperatures and pressures, is liquid and add to depress at normal temperature.When leakage self-saving container of the present invention was idle, second container was in pressurized state, made described gas keep liquid; And in use, second container is in communication with the outside, described gasifying liquefied gas, absorbing environmental heat.Described liquefied gas is preferably and is easy to get, the liquid carbon dioxide of cheapness.
Described second container is the rigidity Pressure Container, preferred cylinder of steel or steel cylinder.But the shape of described second container can be any pressure-proof shape, as cylindric, spherical, coiled pipe shape etc.
Described second container of the present invention has the opening that controllably opens at external environment.Described opening can have one or more.In one embodiment, this opening is manual emptying valve.In another embodiment, this opening is automatic emptying valve.In another embodiment, described second container has manual emptying valve and automatic emptying valve simultaneously.
In one embodiment, also be provided with leakage detection apparatus on described first container, when described leakage detection apparatus detects described dangerous chemical leakage, then this leakage signal passed to control system, control described automatic emptying valve self-opening by control system, and send alarm signal.
In another embodiment, also be provided with temperature sensor on described first container, when described temperature sensor detects ambient temperature above predetermined temperature, then the signal with this temperature anomaly passes to control system, control described automatic emptying valve self-opening by control system, and send alarm signal.
When liquefied gas of the present invention was selected liquid carbon dioxide, those skilled in the art understood the described opening how described second container is set and stop up described opening to prevent the dry ice that forms in the liquid carbon dioxide gasification.
Container of the present invention can be used as all reservoir vessels of producing, store, transporting and use the dangerous chemical that can flow, the security risk that its gas and liquid, especially low-boiling point liquid dangerous chemical that can reduce the dangerous chemical that can flow, danger is especially more effectively produced, stored, transports and use.
