Abstract
This invention relates to the field of safety engineering technology in the petrochemical industry, and discloses an intelligent anti-evaporation device and a method for handling LNG tank area leaks. The intelligent anti-evaporation device includes a support structure comprising a base structure and a support rod. The base structure is located at the bottom of the leak collection pool, and the support rod is detachably fixed to the base structure. A fixed structure is fixed to the support rod, and a self-deploying frame is mounted on the fixed structure. A shape memory alloy spring is mounted on the self-deploying frame to control its opening and closing. The anti-evaporation tarpaulin covers or opens the leak collection pool as the self-deploying frame opens or closes. An automatic switch structure is installed on the self-deploying structure and triggers a fire-fighting function module that closes when the self-deploying structure closes and opens when it opens. This intelligent anti-evaporation device can operate unmanned and intelligently, effectively slowing down and preventing the evaporation and vaporization of LNG in the leak collection pool, greatly reducing the risk of operational accidents and significantly improving the safety factor.
