Non-stored-pressure suspension type superfine dry powder fire extinguishing device

According to the non-stored-pressure suspension type superfine dry powder fire extinguishing device, the flow guide plate with a certain radian is arranged on the outer surface of the gas production agent barrel, the flow guide plate can incline by a certain angle, the gas spraying holes formed in the gas production agent barrel incline by a corresponding angle, the filling coefficient of a superfine dry powder fire extinguishing agent and the bursting pressure range of a bursting disc are reasonably selected, and the gas production efficiency is improved. After the gas generating agent is erupted and before the bursting pressure is reached, the superfine dry powder is blown by high-speed airflow, rotates and is sprayed to the fire extinguishing agent storage tank to generate diffuse reflection, and the superfine dry powder is uniformly distributed in the storage space. The device has the beneficial effects that the spraying distance of the superfine dry powder extinguishing agent is large, the superfine dry
