Problems solved by technology

[0004] The flame directly contacts the DOC carrier and the DPF carrier, and the flame is concentrated, which makes the local temperature of the DPF carrier rise, which not only increases the risk of damage to the DPF carrier, but also has the problem of uneven temperature rise of the DPF carrier and low DPF regeneration efficiency.

Abstract

The invention discloses a combustor turbulent flow assembly and a DPF active regeneration mechanism. The turbulent flow assembly comprises a bearing cylinder and a plurality of turbulent flow blades, the multiple turbulent flow blades are connected with the bearing cylinder and distributed at intervals, and each turbulent flow blade has an included angle relative to the axis of the bearing cylinder; and included angles between at least two turbulent flow blades which are arranged at intervals in the axial direction of the bearing cylinder in the multiple turbulent flow blades and the axis of the bearing cylinder are different. The multiple turbulent flow blades can disturb air flow in multiple directions, so that the turbulent flow and diversion effects are enhanced, flame concentration is avoided, flames are dispersed on a DOC carrier and a DPF carrier, the situation that the temperature of the DPF carrier is too high is not likely to happen, the temperature of the DPF carrier is increased evenly, and the purification effect is good.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a combustor spoiler assembly and a DPF active regeneration mechanism. Background technique [0002] At present, during the operation of the burner, after the oil-gas mixture in the combustion chamber is ignited, the flame is mixed with the exhaust gas and burned in the combustion chamber. At the same time, the flame moves towards the DOC (diesel oxidation catalyst) carrier and the DPF (Diesel Particulate Filter) carrier, and at the same time, the unburned substances in the exhaust gas move to the DOC carrier and the DPF carrier together with the flame . Due to the limited high temperature resistance of the DPF carrier, the DPF carrier is easily damaged when subjected to high temperature. [0003] The inventors found that the existing DPF active regeneration structure has the following disadvantages: [0004] The flame directly contacts the DOC carrier and the ...
