Leakage self-rescue container for stocking danagerous chemicals

Abstract

A rescue device for treating leakage of dangerous chemical includes g a first container having a closed negative pressure chamber and an intake which allows outside dangerous chemicals to enter the first container, and a second container installed and fixed in the first container. The second container contains a substantially harmless liquefied gas and has an opening which controllably communicates with the external environment. When the dangerous chemicals are leaking, the rescue device can be used to reduce the loss of dangerous chemical, alleviate the harm to the environment and human, and avoid the possible disastrous consequences.

1 . A leakage self-rescue container for stocking dangerous chemicals comprising:
 a first container for stocking dangerous chemicals; and   a second container installed and fixed in the first container, the second container contains a substantially harmless liquefied gas and has an opening, which controllably communicates with the external environment.   
     
     
         2 . A leakage self-rescue container of  claim 1 , wherein the second container is a rigid and pressure-resistant container. 
     
     
         3 . A leakage self-rescue container of  claim 1 , wherein the second container is cylindrical, a spherical or snakelike. 
     
     
         4 . A leakage self-rescue container of  claim 1 , wherein 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 contact directly with the first container. 
     
     
         5 . A leakage self-rescue container of  claim 1 , wherein the substantially harmless liquefied gas is liquid carbon dioxide. 
     
     
         6 . A leakage self-rescue container of  claim 1 , wherein the opening is a manual vent valve. 
     
     
         7 . A leakage self-rescue container of  claim 1 , wherein the opening is an automatic vent valve. 
     
     
         8 . A leakage self-rescue container of  claim 7 , wherein the first container has a leak detection device, when the leak detection device detects the leakage of the dangerous chemicals, the automatic vent valve is controlled to open automatically. 
     
     
         9 . A leakage self-rescue container of  claim 7 , wherein the first container has a temperature sensor, when the temperature sensor detects that the ambient temperature is higher than the predetermined temperature, the automatic vent valve is controlled to open automatically. 
     
     
         10 . A leakage self-rescue container of  claim 2 , wherein the second container is one of a cylindrical, a spherical and a snakelike. 
     
     
         11 . A leakage self-rescue container of  claim 2 , wherein 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 contact directly with the first container. 
     
     
         12 . A leakage self-rescue container of  claim 10 , wherein 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 contact directly with the first container. 
     
     
         13 . A leakage self-rescue container of  claim 11 , wherein the opening is a manual vent valve. 
     
     
         14 . A leakage self-rescue container of  claim 12 , wherein the opening is a manual vent valve. 
     
     
         15 . A leakage self-rescue container of  claim 11 , wherein the opening is an automatic vent valve. 
     
     
         16 . A leakage self-rescue container of  claim 12 , wherein the opening is an automatic vent valve. 
     
     
         17 . A leakage self-rescue container of  claim 13 , wherein the first container has a leak detection device, when the leak detection device detects the leakage of the dangerous chemicals, the automatic vent valve is controlled to open automatically. 
     
     
         18 . A leakage self-rescue container of  claim 14 , wherein the first container has a leak detection device, when the leak detection device detects the leakage of the dangerous chemicals, the automatic vent valve is controlled to open automatically. 
     
     
         19 . A leakage self-rescue container of  claim 13 , wherein the first container has a temperature sensor, when the temperature sensor detects that the ambient temperature is higher than the predetermined temperature, the automatic vent valve is controlled to open automatically. 
     
     
         20 . A leakage self-rescue container of  claim 14 , wherein the first container has a temperature sensor, when the temperature sensor detects that the ambient temperature is higher than the predetermined temperature, the automatic vent valve is controlled to open automatically.
