Storage tank anti-explosion exhaust device

A storage tank anti-explosion exhaust device comprises a barrel body and an exhaust cap arranged at the top end of the barrel body; a conical waterproof layer is arranged at the bottom end in the barrel body; an insulation layer is arranged at the connection position between the barrel body and the exhaust cap; the diameter of the exhaust cap is larger than that of the barrel body; an insulation guide device is arranged below the protruded position of the exhaust cap. The storage tank anti-explosion exhaust device is reasonable in structural design, and smart and novel in concept, is mounted at the top ends of storage tanks for materials such as petroleum and chemical materials, and is convenient to use and easy for large-scale promotion and application, the accident that the storage tank is damaged due to the rapid overpressure in the tank caused by accidental reasons is avoided, and the safe fire retardance action is achieved. The storage tank anti-explosion exhaust device is convenient to use, and is easy
