The invention relates to a following type tail gas purification device suitable for a high-power vehicle. The following type tail gas purification device comprises a movable frame, an oxidation catalyst, a particulate filter, a reduction catalyst, a heater, a pressure regulating system, a control system, an energy system and a connection system. Wheels are arranged at the bottom of the movable frame, and the interior of the movable frame is divided into an upper layer and a lower layer. The oxidation catalyst, the particulate filter, the reduction catalyst and the heater are all arranged on the upper layer, and the pressure regulating system is arranged on the lower layer. According to the following type tail gas purification device, by the adoption of a guide rail and sliding block mechanism connection structure and the mode that the heater and the pressure regulating system are combined to work, low exhaust back pressure, dynamic process purification and an automatic regeneration function of the tail gas purification device are achieved; and a good tail gas purification effect can be guaranteed, the device does not occupy too much space and is easy and convenient to use, and the service life of internal related components is prolonged.
Description
technical field [0001] The invention relates to the technical field of exhaust gas purification, in particular to an accompanying exhaust gas purification device suitable for high-power vehicles. Background technique [0002] High-power vehicles with an engine displacement greater than 20L produce serious exhaust pollution during work. In relatively closed places such as factories, tunnels, and workshops, it often causes tears in the eyes, sore throats, and poor breathing of the staff on site, and even causes Brief confusion. Exhaust gas purification devices currently used for high-power vehicles can be divided into two categories: on-board installation and fixed use in workshops. Most of the exhaust purifiers installed on the vehicle use a relatively single purification module, mainly including DOC (oxidation catalyst), DPF (particulate filter), SCR (reduction catalyst) and so on. This technical solution is limited by the installation space of the vehicle, and a single pu...
