The utility model discloses an ammonium oxidizing furnace, characterized by, including air inlet, oxidation furnace main part and gas outlet, the air inlet is located oxidation furnace main part top, and the gas outlet is located oxidation furnace main part below, and the oxidation furnace main part includes water -cooling wall pipe, heat exchange tube, baffle, packing silk screen and sealing drum, and the position of baffle is located the lower limb of bottom heat exchange tube, and the round is encircleed in the space between heat exchange tube and water -cooling wall, and the clearance between baffle and the heat exchange tube is no longer than 10mm, fill the silk screen and be cr20Ni80 alloy silk screen, fill the gap packing between space, heat exchange tube and the sealing drum of silk screen between to water -cooling wall pipe and heat exchange tube. Through fill the silk screen between the dilatation joint, effectively solve technology gas and passed through dilatation joint escape problem, improve the hot recovery efficiency of ammonium oxidizing furnace, reduce the technology temperature degree of oxidation furnace export, stable back process process consideration.
