The invention discloses waste gas treatment equipment. The equipment comprises a steam type dust removal tower, a gas heat exchanger and a combustion chamber, wherein a waste gas inlet is formed in one side of the upper part of the steam type dust removal tower, a waste gas outlet is formed in the other side of the upper part of the steam type dust removal tower, the waste gas outlet communicateswith a waste gas pipe, and the waste gas pipe communicates with a preheating cavity at the lower end of the combustion chamber through the gas heat exchanger; and a combustor and a gas pipe matched with the combustor are arranged in the preheating cavity, a combustion cavity communicating with the preheating cavity is formed in the upper end of the preheating cavity, and a purified gas outlet communicating with the combustion cavity is formed in the upper end of the combustion chamber. The invention further discloses a treatment method on waste gas of the equipment. The waste gas is heated forfour times in the whole process, the temperature is gradually increased, so that the waste gas has a high temperature in the combustion cavity and the combustion chamber, so that the waste gas can befully decomposed or combusted within a short time, the treatment effect of the waste gas is improved, meanwhile, waste heat is fully utilized, the energy is saved, and the environment is protected.
Description
technical field [0001] The invention relates to the field of waste gas treatment, in particular to waste gas treatment equipment and a treatment method thereof. Background technique [0002] The nitriding process has become a common process in metallurgical processing and other fields. However, some waste gas remains after the use of commonly used nitriding furnace equipment. For example, the common waste gas is ammonia gas, which requires waste gas treatment. [0003] In the existing nitriding furnace waste gas treatment process, the waste gas is usually discharged after being treated by gas combustion. However, due to the high decomposition temperature of ammonia gas, in the actual treatment process, the waste gas takes a short time to heat up in the combustion furnace, and usually cannot be completely decomposed or burned, and residual ammonia gas is easily discharged into the surrounding environment; in addition, the existing The exhaust gas is directly discharged after...
