The invention discloses a novel device for classified production of direct method zinc oxide through a tunnel type kiln. The novel device comprises a tunnel type kiln body, a fire grate, a heating device, an automatic coal adding device, an automatic charging device, an air blowing system, a primary zinc oxide cooling dust collecting system, a high-grade zinc oxide cooling dust collecting system,a zinc slag recycling and secondary zinc oxide dust collecting system and a slag outlet system. A semicircular arch crown structure is adopted in the tunnel type kiln body (1), wherein the tunnel typekiln body (1) is composed of four sections including a bottom coal heating section (3), a primary zinc oxide smelting section (4), a high-grade zinc oxide smelting section (5) and a residual zinc recycling and secondary zinc oxide section (6), and the sections are sealed through partitions (7); in addition, the automatic coal adding device (12) is arranged at the left end portion of the bottom coal heating section (3); the automatic charging device (13) is arranged at the upper end portion of the primary zinc oxide smelting section (4); the slag outlet system (14) is arranged at the tail portion of the residual zinc recycling and secondary zinc oxide section (6); and an integral production line is formed. The device has the beneficial effects of direct method zinc oxide produced through aWebster furnace and can also overcome the defect that due to intermittent production of the Webster furnace, efficiency is low, wherein the direct method zinc oxide produced through the Webster furnace has the beneficial effects of being high in grade and good in quality.
