Concentrated sulfuric acid feeding and storing system

The utility model relates to the technical field of chemical production, in particular to a concentrated sulfuric acid feeding and storing system which comprises a temporary storage tank, a supply mechanism, a transfer tank and a storage tank. The input end of the supply mechanism is communicated with the temporary storage tank; the transfer tank is used for receiving concentrated sulfuric acid discharged by the supply mechanism, and the transfer tank is connected with the temporary storage tank through an overflow pipeline; the storage tank is connected with the output end of the transfer tank through a feeding pipe, and a control valve is arranged on the feeding pipe; the top of the storage tank and the top of the temporary storage tank are both connected with exhaust pipes, and pressure release valves are arranged on the exhaust pipes. The concentrated sulfuric acid feeding and storing system can achieve safe unloading, and the unloading risk of workers is reduced. 本实用新型涉及化工生产技术领域，具体涉及一种浓硫酸上料存储系统，包括暂存罐、供给机
