【摘要】：本課題的目標(biāo)是研發(fā)適用于氨氣泄漏的應(yīng)急處置裝置,重點解決當(dāng)前氨氣泄漏事故發(fā)生時,應(yīng)急處置技術(shù)水平低,災(zāi)害持續(xù)時間長,污染物直接排放大氣等問題。針對氨氣泄漏事故開展研究,選取涉氨場所進行實驗應(yīng)用,為事故的應(yīng)急處置裝置提供基礎(chǔ)與保障。 本文首先對示范應(yīng)用場所北京二商集團西郊冷凍廠進行調(diào)研,分析氨氣泄漏最易產(chǎn)生的位置并計算最大泄漏量。針對液氨泄漏事故的特點,設(shè)計應(yīng)急處置流程,包括快速收集單元、低溫等離子體凈化單元、吸附凈化單元,實現(xiàn)多級耦合凈化。本文主要對快速收集單元與吸附凈化單元進行研究,設(shè)計快速收集裝置與活性炭吸附裝置,并設(shè)計監(jiān)控系統(tǒng)實現(xiàn)對凈化過程的實時監(jiān)控。 為滿足低溫等離子體設(shè)備的反應(yīng)條件,本文設(shè)計了快速收集單元包括泡沫吸收塔、噴霧吸收塔與脫水除霧塔,實現(xiàn)對大量泄漏氨氣的快速收集與氣液分離,保障進入等離子體設(shè)備的氣體能被高效消納。對于吸附凈化單元,設(shè)計活性炭吸附裝置,實現(xiàn)尾氣的無害化排空。 本文還設(shè)計了監(jiān)控系統(tǒng),并對整個應(yīng)急處置裝置集成,實現(xiàn)對應(yīng)急處置過程的實時監(jiān)測與集中控制。在此基礎(chǔ)上,模擬氨氣泄漏過程,進行試驗,并對整個系統(tǒng)的凈化性能進行評價,為成果的推廣提供工程實踐支持。
[Abstract]:The goal of this project is to develop an emergency disposal device suitable for ammonia leakage, and to solve the problems of low technical level, long duration of disaster and direct discharge of pollutants when the current ammonia leakage accident occurs. In order to provide the foundation and guarantee for the emergency disposal device, the ammonia leakage accident was studied and the ammonia related sites were selected for experimental application. In this paper, the location of ammonia leakage is analyzed and the maximum leakage quantity is calculated by investigating the application site of Beijing Ershang Group's western suburb freezer plant. According to the characteristics of liquid ammonia leakage accident, the emergency disposal flow is designed, including rapid collection unit, low temperature plasma purification unit and adsorption purification unit to realize multi-stage coupling purification. In this paper, the rapid collection unit and the adsorption purification unit are studied, the fast collection unit and the activated carbon adsorption unit are designed, and the monitoring system is designed to monitor the purification process in real time. In order to meet the reaction conditions of low temperature plasma equipment, a rapid collection unit including foam absorber, spray absorber and dehydrated defog tower was designed to collect and separate a large amount of leaking ammonia gas quickly. Gas entering the plasma equipment is guaranteed to be efficiently absorbed. For the adsorption purification unit, the activated carbon adsorption unit is designed to realize the harmless discharge of tail gas. This paper also designs the monitoring system and integrates the whole emergency disposal device to realize the real-time monitoring and centralized control of the emergency disposal process. On this basis, the ammonia leakage process is simulated, the experiment is carried out, and the purification performance of the whole system is evaluated, which provides engineering practical support for the popularization of the results.
