Abstract

The invention relates to an ammonia gas leakage protecting device which comprises a first ammonia gas detecting unit, a second ammonia gas detecting unit, a data collection control unit, a refrigeration action unit, a single freeze action unit, a communication unit and an emergency illuminance unit. The first ammonia gas detecting unit is arranged in a refrigerating station, the second ammonia gas detecting unit is arranged in a single freezing area, and ammonia gas detectors are arranged in the two ammonia gas detecting units. The data collection control unit comprises a data collection module, a comparison module, a storage module and a logic control module. The refrigeration action unit comprises a first exhaust fan controller, a first spray controller and a first valve controller. The ammonia gas leakage protecting device can detect the ammonia concentration in the refrigerating station and in the single freezing area of a manufacturing shop. In addition, after data collection, all controllers are started, and loss caused by ammonia gas leakage can be prevented.

Description

technical field [0001] The invention relates to a gas leakage protection device, in particular to an ammonia gas leakage protection device which performs redundant judgment on collected data. Background technique [0002] With the rapid development of industry, there are more and more places where human beings are exposed to harmful gases, which causes more and more harm to human beings. The repeated poisoning accidents make people clearly realize that while developing industry The importance of protecting human security. Therefore, the ammonia leak detector has gradually become an indispensable protective equipment in industrial safety production. [0003] Devices and methods for detecting harmful gases in the prior art already exist and have even been applied to actual production, such as the Chinese patent "Automatic Gas Leakage Detection Method", patent publication number CN100480662C, which discloses an automatic detection method for gas leakage, including the followin...
