Abstract
A rescue device for treating leakage of dangerous chemical includes 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.
Claims20
A rescue device for treating leakage of dangerous chemicals comprising:
- 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.
A rescue method for treating leakage of dangerous chemicals comprising:
- (1) providing a rescue device, which comprises:
- 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;
- (2) connecting the intake which allows the outside dangerous chemicals to enter the first container with a container, in which the dangerous chemicals are leaking, so as to introduce the dangerous chemicals which are not leaking into the rescue device;
- and
- (3) opening the opening of the second container and releasing the substantially harmless liquefied gas in the second container so that the temperature and pressure in the first container reduce so as to introduce more dangerous chemicals which are not leaking into the rescue device.
