Definitions

  • the present invention relates to a container for stocking dangerous chemicals, in particular, to a leakage self-rescue container for stocking dangerous chemicals.
  • Chemicals are indispensable to the industrial production and the people's living. Moreover, most of the chemicals are dangerous chemicals, in which most of them are fluids including gasses and liquids, especially liquids with low boiling points. During the production, storage, transportation and use of dangerous chemicals, leakage problems sometimes occur due to the aging of a container, high temperature and accidents, which will lead to the harm to the environment and even result in disastrous consequences. Prompt and effective self-rescue will gain more valuable time for rescue and therefore it will be more possible to reduce the harm and avoid the disastrous consequences.
  • JP 2005-297994 relates to a liquefied natural gas tank, which is carried on a traveling car body.
  • a low boiling point liquid tank which is filled with a low boiling point liquid having a boiling point lower than that of the liquefied natural gas, is arranged in the center of the interior of the gas tank.
  • JP 10318497 discloses a leakage self-rescue container having cooling means circulating in a pipe system.
  • the present invention relates to a leakage self-rescue container for stocking dangerous chemicals having the features of claim 1. It comprises:
  • the temperature in the first container decreases and thereby the pressure in the first container reduces by releasing the liquefied gas in the second container so as to avoid the leakage or explosion of the first container caused by overpressure, or to increase the viscosity of the dangerous chemicals to reduce the leakage rate when the leakage occurs so that it can obtain valuable time for more effective rescue.
  • the leakage self-rescue container of the present invention can be used for stocking flammable, explosive, toxic, corrosive, radioactive or chemical polluted dangerous chemicals, in particular for stocking more dangerous gasses or fluids, especially dangerous chemicals such as fluids with low boiling points and the like.
  • the dangerous chemicals include but are not limited to phosphorus oxychloride, gasoline, bromine, liquid ammonia, liquid chlorine, liquid hydrogen sulfide, hydrocyanic acid, methyl isocyanate, ethylene oxide, natural gas, liquefied petroleum gas, alcohol, chloroform, and the like.
  • the first container for stocking dangerous chemicals can be selected based on the properties of chemical products stocked in the container.
  • Various conventional containers in the art for stocking dangerous chemicals can be used.
  • the leakage self-rescue container of the present invention can be a separate container, and can be a container loaded by any vehicle.
  • a second container is installed in the first container.
  • the second container contains a harmless liquefied gas.
  • the liquefied gas can be released in the form of gas from the second container by opening a vent valve on the second container.
  • the release of the liquefied gas absorbs the heat of the surrounding environment (i.e. the first container) so that the temperature of the container decreases and thereby the pressure in the first container reduces so as to avoid the leakage or explosion caused by overpressure, or to increase the viscosity of the dangerous chemicals to reduce the leakage rate when the leakage occurs and to obtain valuable time for more effective rescue.
  • the second container can be fixed in the first container with a method well-known to one skilled in the art.
  • the relative position of the second container to the first container is that the center of the second container is closed to the center of the first container while the second container does not directly contact with the first container so that the second container mainly exchanges the heat with the interior of the first container but does not exchanges the heat with the external environment through the walls of the first container.
  • the liquefied gas in the second container can be selected from a gas, of which the critical temperature is above the ambient temperature and which is harmless to environment and human.
  • the liquefied gas is a gas under the air pressure at the ambient temperature, but it is a liquid under pressure at the ambient temperature.
  • the second container is under pressure and the gas is maintained as a liquid.
  • the second container communicates with the outside and the liquefied gas is gasified and absorbs the environmental heat.
  • the liquefied gas is liquid carbon dioxide, which is readily available and inexpensive.
  • the second container is a rigid and pressure-resistant container, preferably a steel tank or cylinder.
  • the second container can be pressure-resistant in any shape such as cylindrical, spherical, snakelike tube and the like.
  • the second container of the present invention has an opening, which controllably communicates with the external environment.
  • the second container has one or more openings.
  • the opening is a manual vent valve.
  • the opening is an automatic vent valve.
  • the second container has not only a manual vent valve but an automatic vent valve.
  • the first container also has a leak detection device.
  • the leak detection device detects the leakage of the dangerous chemicals
  • the leakage signal is delivered to a control system.
  • the control system controls to open the automatic vent valve automatically and sends out an alarm signal.
  • the first container also has a temperature sensor. Where the temperature sensor detects that the ambient temperature is higher than a predetermined temperature, the abnormal temperature signal is delivered to a control system. The control system controls to open the automatic vent valve automatically and sends out an alarm signal.
  • the liquefied gas of the present invention is selected to be liquid carbon dioxide
  • a person skilled in the art knows how to arrange the openings of the second container so as to prevent dry ice formed during the gasification of liquid carbon dioxide from blocking the openings.
  • the container of the present invention can be used as a storage container for producing, stocking, transporting and using liquid dangerous chemicals. It can reduce the security risks for producing, stocking, transporting and using liquid dangerous chemicals including more dangerous gasses and fluids, especially dangerous chemical fluids with low boiling points.
  • the same component has the same number.
  • the number of the first container is 101 in Figure 1
  • the number of the first container is 201 in Figure 2
  • so on the same component has the same number.
  • Figure 1 is a schematic diagram of an embodiment of the present invention.
  • a second container 103 is fixed in a first container 101 for stocking dangerous chemicals 102 via supports 104.
  • the second container 103 is cylindrical.
  • the second container 103 contains a liquefied gas 105.
  • a liquid-level sensor (not shown) can be installed in the second container 103 to detect the amount of the liquefied gas 105 in the second container 103 at any time and to complement the liquefied gas 105 where needed.
  • the second container 103 has a vent valve 106, which controllably communicates with the external environment.
  • the second container 103 may have one or more vent valves 106.
  • the liquefied gas 105 can be injected or complemented into the second container 103 through the vent valve 106 or other feed inlets (not shown).
  • the vent valve 106 When the first container 101 leaks due to an accident or is threatened by high temperature, the vent valve 106 is opened to release the liquefied gas 105 in the second container 103. During the release, the liquefied gas 105 absorbs the heat of the surrounding environment (i.e. the first container 101) so that the temperature of the first container 101 decreases and thereby the pressure in the first container 101 reduces so as to avoid the leakage or explosion of the first container 101 caused by overpressure, or to increase the viscosity of the dangerous chemicals 102 to reduce the leakage rate when the leakage occurs.
  • the liquefied gas 105 absorbs the heat of the surrounding environment (i.e. the first container 101) so that the temperature of the first container 101 decreases and thereby the pressure in the first container 101 reduces so as to avoid the leakage or explosion of the first container 101 caused by overpressure, or to increase the viscosity of the dangerous chemicals 102 to reduce the leakage rate when the leakage occurs.
  • FIG. 2 is a schematic diagram of another embodiment of the present invention.
  • a snakelike tubular second container 203 is fixed in a first container 201 for stocking dangerous chemicals 202.
  • the second container 203 contains a liquefied gas 205.
  • the second container 203 has a vent valve 206, which controllably communicates with the external environment, and a feed inlet 207, through which the liquefied gas 205 are injected.
  • the second container 203 may have one or more vent valves 206 and one or more feed inlets 207.
  • the first container 201 has a leak detection device or a temperature sensor 208.
  • the leak detection device or the temperature sensor 208 detects that the first container 201 leaks or is threatened by high temperature
  • the detecting signal is delivered to a control system 209.
  • the control system 209 controls to open or partly open the vent valve 206 to release the liquefied gas 205 in the second container 203. During the release, the liquefied gas 205 absorbs the heat of the surrounding environment ( i.e .
  • the first container 201) so that the temperature of the first container 201 decreases and thereby the pressure in the first container 201 reduces so as to avoid the leakage or explosion of the first container 201 caused by overpressure, or to increase the viscosity of the dangerous chemicals 202 to reduce the leakage rate when the leakage occurs.
