Abstract

A method and apparatus for obtaining the leakage damage radius of a liquid ammonia storage tank is provided by the embodiments of the invention. The method includes judging whether a cloud formed by leakage of the liquid ammonia storage tank is a heavy gas cloud or not based on the leakage flash amount of the liquid ammonia storage tank, and determining whether the leakage damage radius of the liquid ammonia storage tank is a heavy gas cloud; the corresponding damage radius being obtained based on the judgment result of whether the cloud formed by the leakage of the liquid ammonia storage tankis a heavy gas cloud. According to the method and apparatus for obtaining a leakage damage radius of a liquid ammonia storage tank provided by an embodiment of that present invention, by setting to determine whether the cloud formed by the leakage of the liquid ammonia storage tank is a heavy gas cloud, and based on the judgment results, the corresponding damage radius can be obtained, which cancombine the diffusion of heavy gas cloud and non-heavy gas cloud organically, so that the diffusion process of dangerous substances becomes a continuous change process, and the damage radius of leakage concentration diffusion of liquid ammonia storage tank can be accurately obtained.

Description

technical field [0001] The embodiments of the present invention relate to the field of liquid nitrogen storage tank leakage accident handling, and more specifically, relate to a method and equipment for obtaining the damage radius of a liquid ammonia storage tank leakage. Background technique [0002] Nowadays, many industrial enterprises use liquid ammonia for refrigeration in the production process, and liquid nitrogen storage tanks are widely used. However, in the event of a leakage accident, the leaked ammonia gas may cause serious harm to the surrounding environment and residents. When an accident occurs, evacuation of personnel is one of the effective solutions to deal with such emergencies. When selecting a personnel evacuation scheme, how to establish a scientific and effective leakage concentration diffusion analysis method, that is, how to obtain the damage radius of the liquid ammonia storage tank leakage Accident emergency response and auxiliary decision-making a...
