The invention discloses an environment-friendly top cover structure for a rail car and the rail car, and relates to the field of rail car top covers. The structure comprises: a mounting groove which is formed in a top cover of the rail car, and is recessed towards a carriage of the rail car; a tail gas post-treatment device which is arranged on the side, close to the carriage, of the groove bottom of the mounting groove, wherein the output end of the tail gas post-treatment device penetrates through the top cover and extends to the side, away from the carriage, of the groove bottom of the mounting groove; and a silencer which is arranged in the mounting groove, wherein the input end of the silencer is opposite to the output end of the tail gas after-treatment device, and the silencer is used for silencing the tail gas after-treatment device. The tail gas post-treatment device is arranged on the top cover of the rail car, the tail gas of a diesel engine is treated and then exhausted, the silencer is arranged at the output end of the tail gas post-treatment device, and operation noise of the diesel engine and the tail gas post-treatment device is treated, so that emission meets the national environmental protection requirement, the influence on the surrounding environment of a rail line is reduced, the replacement time is shortened, and the replacement cost is reduced.
本发明公开了一种轨道车用环保顶盖结构及轨道车,涉及轨道车顶盖领域,包括:安装槽,开设于轨道车的顶盖上,安装槽向轨道车的车厢方向凹陷;尾气后处理装置,设置于安装槽的槽底靠近车厢方向的一侧,尾气后处理装置的输出端穿设于顶盖延伸至安装槽的槽底远离车厢方向的一侧;消音器,设置于安装槽内,消音器的输入端与尾气后处理装置的输出端相对设置,消音器用于对尾气后处理装置进行消音;轨道车顶盖设置尾气后处理装置,对柴油机的尾气进行处理再排放,并且尾气后处理装置的输出端设置消音器,对柴油机和尾气后处理装置的运行噪音进行处理,这样使排放符合国家环保要求,减少对线路周围环境的影响,缩短更换时间,降低更换成本。
