Method for emergency disposal of ammonia leakage of liquid ammonia tank through water spray adsorption

Abstract

The invention discloses a method for emergency disposal of ammonia leakage of a liquid ammonia tank through water spray adsorption. According to the method, an emergency system for treating ammonia leakage of the liquid ammonia tank through water spray adsorption is arranged at the periphery of the liquid ammonia tank; the emergency system for treating ammonia leakage of the liquid ammonia tank leakage ammonia through water spray adsorption comprises a water spray water supply pump, wherein a water inlet of the water spray water supply pump is communicated with a water source through a water convey pipeline, a water outlet of the water spray water supply pump is communicated with a water inlet of a water spray water convey pipe, a filter and a water convey electric valve are sequentially connected in series to the water spray water convey pipe from the water inlet end to the water outlet end, and a water draining opening is arranged on the water spray water convey pipe and located on apipe section from the water inlet end to the filter. The invention aims at providing the method for emergency disposal of ammonia leakage of the liquid ammonia tank through the water spray adsorption. The method has the advantages of high reliability, high response speed and high treating efficiency; the method can achieve quick linkage when ammonia leakage is detected; the method can achieve effective treatment and ensure personnel security.

Description

technical field [0001] The invention relates to a water spray adsorption method for emergency treatment of ammonia leakage from a liquid ammonia storage tank. Background technique [0002] As a refrigeration medium, ammonia has the advantages of easy availability, low price, large unit cooling capacity, high heat release coefficient, small flow resistance, and simple supporting pipelines. It has been widely popularized and applied in refrigeration processes in many industries. A storage tank is set up to store liquid ammonia, but ammonia is also highly toxic, flammable and explosive. The "8.31" major ammonia leakage accident of Shanghai Wengpai Refrigeration Industry Co., Ltd. occurred due to ammonia leakage. Yuanfeng Poultry Industry Co., Ltd. "6.3" particularly serious fire and explosion accidents, etc., caused serious casualties, huge property losses and bad social impact. The current emergency measures to deal with the ammonia leakage of the liquid ammonia storage tank ...

[0002] As a refrigeration medium, ammonia has the advantages of easy availability, low price, large unit cooling capacity, high heat release coefficient, small flow resistance, and simple supporting pipelines. It has been widely popularized and applied in refrigeration processes in many industries. A storage tank is set up to store liquid ammonia, but ammonia is also highly toxic, flammable and explosive. The "8.31" major ammonia leakage accident of Shanghai Wengpai Refrigeration Industry Co., Ltd. occurred due to ammonia leakage. Yuanfeng Poultry Industry Co., Ltd. "6.3" particularly serious fire and explosion accidents, etc., caused serious casualties, huge property losses and bad social impact

The current emergency measures to deal with the ammonia leakage of the liquid ammonia storage tank are to install spray water above the liquid ammonia storage tank, which cannot deal with the ammonia leakage comprehensively, quickly and efficiently, and there are great risks and hidden dangers
