The invention discloses a marine diesel engine waste gas desulfurization and denitrification treatment device which comprises a mixing pipe assembly, a catalytic device, a soot blowing pipe assembly, a bypass pipeline, an electromagnetic valve and a thermometer. The fixed adjusting device and the manhole sealing device are mounted on the catalytic device, so that a catalyst can effectively and completely react and filter waste gas from a mixing pipe. And the manhole sealing device effectively prevents air leakage of equipment. A part of diesel engine waste gas enters the mixing pipe through the gas inlet, urea is jetted into the flue gas, and the fan blades mix and reflect airflow and urea. And entering a catalytic device, and effectively carrying out desulfurization and denitrification treatment through a catalyst. And a soot blowing pipeline is arranged on the catalytic device and is used for blowing away dust concentrated in a catalyst in the catalytic device at regular time, so that the cleanliness of the catalyst filtering device is ensured. And the other part of gas enters from the tail side of the catalytic device through the bypass pipeline for cyclic catalysis, so that the problems of complete reaction of the catalyst and gas sealing of the device are solved, and the use efficiency of the catalyst and the quality of discharged gas are improved.
本发明公开了一种船用柴油机废气脱硫脱硝处理装置,包括混合管总成、催化装置、吹灰管总成、旁通管路、电磁阀、温度计。本发明在催化装置安装固定调节装置及人孔密封装置,保证催化剂能将混合管进来的废气有效完全反应过滤。人孔密封装置有效的防止设备漏气。柴油机废气通过进气口一部分气体进入混合管,尿素喷射进烟气,扇叶将气流与尿素混合反映。进入催化装置通过催化剂有效的进行脱硫脱硝处理。催化装置上面装有吹灰管路,定时将催化装置里面的催化剂集中的灰尘吹散,保证催化剂过滤装置的洁净。另一部分气体通过旁通管路从催化装置尾侧进入进行循环催化,解决了催化剂完全反应及气体密封装置问题,提高催化剂使用效率和排放气体质量。
