Liquid ammonia storage tank remote control monitoring and automatic sprinkling system realization method

Abstract

This invention discloses a method of ammonia liquid storage tank remote monitoring and automatic spraying system. This system can real -time on-line monitor operational conditions of storage tank and provide rapid remote processing if ammonia liquid accidentally leak. The remote photographical monitoring system can monitor the device operating state directly. When ammonia liquid leaking, the remote pneumatic cut-off valve intercepts the storage tank out of the flow quickly. At the same time, the ammonia on-line monitor and automatic spraying system can dilute the ammonia liquid and ammonia into waste liquid, which is then transferred to other working procedure by waste liquid pump. Thus, it effectively decreases ammonia leaking pollution. This invention is safe, simple and low cost.

Description

technical field [0001] The invention relates to the remote monitoring of the operating status of toxic, harmful, volatile and dangerous chemical storage equipment, and the remote processing of sudden leakage accidents of storage equipment, and is suitable for effective monitoring and emergency treatment of liquid ammonia storage equipment, which may occur Environmental pollution accidents are minimized. Background technique [0002] The storage of toxic and harmful materials as raw materials and intermediate products in the chemical industry is difficult to operate in terms of safety and emergency rescue measures, which is a problem faced by almost all chemical production units. Taking the common liquid ammonia storage as an example, liquid ammonia leakage accidents are sudden and difficult to comprehensively monitor through patrol inspections and other measures. Once a leakage occurs, it will immediately spread into gaseous ammonia. The scene is full of smoke and pungent sm...

AI Technical Summary

Problems solved by technology

However, most of the on-site valves are manually operated, which is difficult to close, and liquid ammonia is highly corrosive, so it is difficult to ensure that the on-site valves are completely cut off, and the leakage is difficult to completely solve

The tank area has high pressure, large leakage, and fast diffusion, which can easily cause large-scale air pollution

The mixture of ammonia and air reaches the explosion limit, which will easily cause combustion and explosion. If there is oil or other flammable substances, the danger will be higher
