Abstract

The invention relates to the technical field of waste gas purification, in particular to an ammonia decomposition furnace for exhaust of a heat treatment nitriding furnace. The bottom of the furnace body is fixedly connected with an air inlet pipe, and the top is fixedly connected with an exhaust pipe; the gas purification device is arranged in the furnace body; the ammonia gas purification device comprises an ammonia gas decomposition mechanism which is fixedly connected to the center of the furnace body and makes contact with waste gas and a temperature control mechanism which is fixedly connected to the inner wall of the furnace body and used for controlling the temperature in the furnace body. After waste gas containing ammonia gas is fed into the furnace body through the gas inlet pipe, the waste gas passes through the ammonia gas decomposition mechanism, the ammonia gas decomposition mechanism decomposes the ammonia gas in the waste gas to enable the ammonia gas to be decomposed into nitrogen and hydrogen, the waste gas purified by the ammonia gas decomposition mechanism is exhausted out of the furnace body through the gas exhaust pipe, and the effect of purifying the ammonia gas in the tail gas is achieved.

Description

technical field [0001] The invention relates to the technical field of exhaust gas purification, in particular to an ammonia decomposition furnace for heat treatment of nitriding furnace exhaust gas. Background technique [0002] Nitriding treatment refers to a chemical heat treatment process in which nitrogen atoms penetrate into the surface of the workpiece in a certain medium at a certain temperature. Nitrided products have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. Nitriding furnace is equipment with nitriding treatment, which has the characteristics of low treatment temperature, short time, small deformation of workpiece, high fatigue limit and good wear resistance. The nitriding furnace will discharge waste gas during use. When the waste gas is not fully burned, residual ammonia gas will be discharged into the atmosphere, which will affect the environment of the workshop and factory area, and have certain harm ...
