Intelligent safety protection system for liquefied natural gas terminal tank zone

Abstract

The invention discloses an intelligent safety protection system for a liquefied natural gas terminal tank zone, and belongs to the technical field of tank zone safety systems. The liquefied natural gas terminal tank zone comprises a gas detection module, a leakage alarm module, a fire detection module, a fire alarm module, a TV monitoring module, a broadcasting system module and an access controlmodule, wherein the gas detection module is used for monitoring gas concentration in a tank zone; the leakage alarm module is used for making an alarm when the gas concentration value exceeds the limit; the fire detection module is used for detecting the temperature and smoke concentration in the tank zone; the fire alarm module is used for making an alarm when the temperature or smoke concentration exceeds the limit; the TV monitoring module is used for recording an accident site image and playing the accident site image on a large screen; the broadcasting system module is used for playing voice information; and the access control module is used for controlling a controlled gate at each entrance/exit in the tank zone. Through adoption of the intelligent safety protection system, in the case of an accident, accident information can be played through the large screen and a broadcasting device, and meanwhile all controlled gates are opened simultaneously to instruct people in the tank zone to handle with a dangerous source or get out of a dangerous zone.

Description

technical field [0001] The invention relates to the technical field of tank area safety systems, in particular to an intelligent safety protection system for a liquefaction wharf tank area. Background technique [0002] At present, there are usually a large amount of liquid chemical raw materials in the terminal tank area. Once these liquid chemical raw materials leak, they will release a large amount of toxic and flammable gases, which will cause harm to the personnel in the terminal. The raw materials and flammable gases leaked at the same time are extremely prone to explosion, causing serious economic losses. Therefore, safety protection systems are usually installed in the tank area of ​​the liquefaction terminal. These safety protection systems usually use a variety of sensors to monitor the tank area in real time, and activate an alarm when an accident occurs, so that the personnel in the tank area can quickly evacuate or monitor the accident area. Fast processing. ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when an accident occurs, even if the safety protection system activates the alarm, it is still difficult for the personnel in the tank farm to know the accident information, and it is not very helpful for the personnel in the tank farm to escape or deal with the danger source
