The utility model relates to a unload acid-base technique, specifically a unload acid-base pipeline superpressure alarm device.
Background
In the production process of a power plant, in order to ensure the normal operation of an acid-base system, concentrated acid and concentrated alkali need to be purchased regularly. After the purchased concentrated acid and concentrated alkali are transported to a power plant by an acid-alkali tank wagon, the concentrated acid and the concentrated alkali need to be discharged into an acid-alkali tank through an acid-alkali discharging hose. In the acid and alkali discharging process, if the acid and alkali discharging hose is unsmooth or blocked, the acid and alkali discharging hose is very easy to generate overpressure, so that acid and alkali are leaked, and environmental pollution and personnel injury are caused. Therefore, the acid and alkali discharge pipeline overpressure alarm device is needed to be invented to solve the problem of acid and alkali leakage caused by overpressure of the acid and alkali discharge hose.
