The traditional view is that the conversion process of pyrite acid production only needs to maintain the heat balance of the converter itself. Therefore, many pyrite acid production enterprises have not recycled the surplus heat of the conversion process for many years. , but SO 3 The dew point of

Abstract

The invention provides a device for recycling waste heat generated in a procedure of acid making and conversion of sulphide ore, belonging to the field of recycling residual heat resources. The device for recycling the waste heat generated in the procedure of acid making and conversion of sulphide ore comprises a heat exchanger and an absorption tower, and is characterized in that a connecting heat pipe evaporator is arranged between the heat exchanger and the absorption tower, and the heat pipe evaporator is merged into a low-pressure steam through a steam manifold. The heat pipe evaporator comprises a flue gas channel (1), a heat pipe (2), water sleeves (3), an ascending pipe (4), a steam manifold (5) and a descending pipe (6), wherein the heat pipe (2) is arranged in the flue gas channel (1), the water sleeves (3) are respectively arranged on the upper end of the heat pipe (2), the water sleeve (3) is connected with the steam manifold (5) through the ascending pipe (4), the steam manifold (5) is connected with another water sleeve (3) through the descending pipe (6). The device has the advantages of small flow resistance, high heat transfer efficiency, compact device structure, light weight, and convenience for maintenance, and effectively prevents the boiler feed water from leaking in the fuel gas channel.
