Method for treating ammonia leakage of freezing device by synchronous spraying isolation and spraying absorption

Abstract

The invention discloses a method for treating ammonia leakage of a freezing device by synchronous spraying isolation and spraying absorption. An emergency system for treating ammonia leakage of the freezing device by synchronous spraying isolation and spraying absorption is arranged at the peripheral edge of the freezing device with ammonia as a refrigerating medium, and includes a water curtain water supply pipe; the water curtain water supply pipe is encircled above the outer side of the peripheral edge of the freezing device with ammonia as the refrigerating medium in the horizontal direction by 0.3-0.8 m, and is provided with multiple water curtain nozzles; and the multiple water curtain nozzles can downwards spray water in the vertical direction to form a continuous water curtain for surrounding the whole side surface of the peripheral edge of the freezing device. The invention aims to provide the method for treating ammonia leakage of the freezing device by synchronous spraying isolation and spraying absorption, which is reasonable in layout design, high in stability, flexible in operation and sensitive in response, can precisely detect the ammonia leakage and provides the safety guarantee for emergency disposal and person evacuation.

Description

technical field [0001] The invention relates to a method for synchronous spray isolation and spray adsorption treatment of ammonia leakage from a freezing device. Background technique [0002] Ammonia has the advantages of small specific gravity and viscosity, high heat release coefficient, cheap price, easy to obtain, and does not destroy the ozone layer. Therefore, it is widely used in modern industrial refrigeration processes, especially ammonia is commonly used as a refrigeration medium in freezing devices. However, ammonia also has Strong toxicity, flammability and explosiveness. Once leaked, serious accidents are likely to occur. The current emergency treatment methods for leaked ammonia are generally interlocking exhaust or spray isolation, but neither can achieve comprehensive and efficient emergency treatment. Greater risk of accident. Considering the fact that ammonia is very soluble in water, only by using spray adsorption to treat leaked ammonia while spraying a...
