Automatic absorption and reuse device for overpressure discharge of ammonia from ammonia tank

Abstract

The invention belongs to the technical field of environmental protection engineering, and in particular relates to an automatic absorption and reuse device for overpressure discharge of ammonia from an ammonia tank, and the automatic absorption and reuse device comprises an ammonia tank and a water seal tank arranged above the ammonia tank. The top plate of the ammonia tank is provided with an ammonia outlet and an ammonia inlet, the side wall of the water seal tank is provided with an ammonia inlet and an ammonia outlet, the ammonia outlet is communicated with the ammonia inlet through an airduct, the ammonia outlet is communicated with the ammonia inlet through an overflow pipe, the ammonia inlet is positioned below the liquid level of the water seal tank, and the ammonia outlet is positioned above the ammonia inlet. The automatic absorption and reuse device for ammonia gas discharged under overpressure of the ammonia tank provided by the invention can efficiently and automaticallyrecycle the ammonia gas discharged under overpressure from the ammonia tank, and the device is capable of not only saving the production and operation cost, but also reducing the harm to the environment and staff in the storage tank area, and being suitable for recycling the ammonia gas in the field of environmental protection or the chemical industry.

Description

technical field [0001] The invention belongs to the technical field of environmental protection engineering, and in particular relates to an automatic absorption and reuse device for ammonia gas discharged from an ammonia water tank under overpressure. Background technique [0002] Selective Catalytic Reduction (SCR) is currently the most widely used flue gas denitrification technology in the world, and is widely used in waste gas treatment in metallurgy, electric power and medical industries. Liquid ammonia and ammonia water are the primary reducing agents to be considered, but liquid ammonia requires strict safety control measures, which limits its application. During the storage of ammonia water, ammonia gas will inevitably be discharged due to overpressure to prevent damage to the storage tank. Ammonia gas is a gas with a pungent smell. If it is discharged directly, it will pollute the air environment and cause harm to the health of the workers in the storage tank farm....

AI Technical Summary

Problems solved by technology

At present, the vast majority of enterprises do not have recycling devices, or a small number of them are equipped with absorption tanks, but manual operation is required, which has certain limitations.
