The utility model provides a pressure relief device used for a centrifugal blast pressure fan. The pressure relief device comprises a tee coupling, an oil-mist separator arranged on the tee coupling and an exhaust pipe arranged at the left end of the tee coupling, wherein the lower end of the tee coupling is connected to an oil tank, and a dust screen is arranged on one end, which is far away from the tee coupling, of the exhaust pipe. The pressure relief device has the following advantages that after the structure is adopted, an oil-steam mixture enters the tee coupling through the top of the oil tank, the upper end of the tee coupling is connected to the oil-mist separator, so that the oil and the steam are separated, and owing to pressure difference, the gas enters a copper pipe from the left side of the tee coupling and is finally discharged into the atmosphere. Meanwhile, the dust screen is arranged at the port of the exhaust pipe so as to prevent gas particles from blocking the exhaust pipe.
